My friend Alf, LA2NTA, has sent med these screenshots from when he has been operating FT8. The first image is when operating 10 meters and took place early in November.

Two of LA2NTA CQs being received by himself on 10 meter (in red)

It shows how his own CQ comes back to him at 10.54.00 and at 11.00.00 and is decoded in his own receiver.

The second example is from 20 meters and took place just a few days ago.

For my day job in the test and measurement industry, I get involved in measurement solutions for wireless communications. Right now, the big technology wave that is about to hit is known as 5G (fifth generation wireless). Your mobile smartphone probably does 4G or LTE as well as the older 3G digital mobile standards. For more detail on LTE, see ExtremeTech explains: What is LTE?

5G will be the next cool thing with early rollouts planned for 2018. The design goals of 5G are very aggressive, with maximum download speeds of up to 20Gb/s. (See what I did there: I used the words “up to”, so don’t expect this performance under all conditions.) The actual user experience has yet to play out but we can assume that 5G is going to be blazing fast. For more details see: Everything You Need to Know About 5G. To achieve these high bandwidths, 5G will use spectrum at higher frequencies. Move up in frequency and you inherently get more bandwidth. The FCC recently allocated 11 GHz of new spectrum for 5G, including allocations at 28 GHz, 37 GHz, 39 GHz and 64-71 GHz: FCC 5G spectrum allocation demands 3 breakthrough innovations . Yes, those frequencies are GHz with a G…that’s a lot of cycles per second.

Amateur Radio

So my day job is focused on wider bandwidths and higher frequencies. Then I go home and play amateur radio which is a narrowband, low frequency activity. The heart of ham radio operation is on the HF bands, 3 to 30 MHz, almost DC by 5G standards. Many of us enjoy VHF and UHF but even then most of the activity is centered on 50 MHz, 144 MHz, maybe 432 MHz. I recently started using 1.2 GHz for Summits On The Air, so that at least gets me into the GHz-with-a-G category.

Not only does ham radio stay on the low end of the frequency range, we also use low bandwidth. The typical phone emission on the HF bands is a 3-kHz wide SSB signal. That’s kHz with a k. As we go higher in frequency, some of our signals are “wideband” such as a 16-kHz wide FM signal on the 2m band. In terms of digital modes, AX.25 packet radio and APRS typically use 1200 baud data rates but sometimes we go with a “super-fast” 9600 transmission mode. CW is still a very popular narrowband mode with bandwidths around 200 Hz, depending on Morse code operating speed. Lately, the trend has been to go even narrower in bandwidth to keep the noise out and operate at amazingly low signal-to-noise ratios. Some of the WSJT modes use bandwidths in the range of 4 to 50 Hz.

There are some good reasons that amateur radio remains narrowband. The two most important are:

1. We love the ionosphere and what it does for radio propagation. The HF bands are great for making radio signals go around the world but they are narrow spectrum. For example, the 20m band is 350 kHz wide, going from 14.000 to 14.350 MHz. Operation is restricted to narrowband modes, else we’d use up the entire band with just a few signals.
2. We just want to make the contact (and maybe talk a bit). For the most part, radio hams are just trying to make the contact. This is most pronounced during a DX pileup or during a contest when you’ll hear short exchanges that provide just the minimal amount of information. Some of us like to talk…rag chew…but that can be accomplished with narrowband (SSB) modulation with no problem. I suppose it would be handy from time to time to be able to send a 3 MB jpg file to someone I am working on 20m but that’s not the main focus of a radio contact.

Of course, not all amateur radio operation is below 1 GHz. There’s always someone messing around at microwave and millimeter wave frequencies. I’ve done some mountaintop operating at 10 GHz and achieved VUCC on that band. Recently, the ARRL announced a new distance record of 215 km on the 47 GHz band.

ICOM produced a D-STAR system at 1.2 GHz with a data rate of 128kbps, quite the improvement over AX.25 packet. However, adoption of this technology has been very limited and it remains a single-vendor solution.

There is significant work going on with High-Speed Multimedia (HSMM) Radio which repurposes commercially-available 802.11 (“WiFi”) access equipment.  Broadband-Hamnet is focused primarily on using 2.4 GHz band to create mesh wireless mesh networks. Amateur Radio Emergency Data Network (AREDN) is doing some interesting work, mostly on the 2.4 GHz and 5.8 GHz bands. The HamWAN site has lots of information about a 5.8 GHz network in the Puget Sound area. The basic theme here is use commercial gear on adjacent ham bands…a common strategy for many VHF and higher ham radio systems.

Also worth mentioning is the FaradayRF work, currently aimed at creating a basic digital radio for the 33cm (902 MHz) amateur band. The raw data transfer rate is around 500 kbaud.

There are probably some other high-speed digital systems out there that I’ve missed but these are representative.

Infrastructure Rules

A critical factor in making LTE (and 5G) work is the huge investment in infrastructure by Verizon, AT&T and others. With cellular networks, the range of the radio transmission is limited to a few miles. One of the trends in the industry is toward smaller cells, so that more users can be supported at the highest bandwidths. With 5G moving up in frequency, small cells will become that much more important.

On the other hand, most amateur radio activity is “my radio talking to your radio” without any infrastructure in between. Most of us like the purity and simplicity of my station putting out electromagnetic waves to talk directly to fellow hams. In many cases, this simplicity and robustness has played well under emergency and disaster conditions.

FM (and digital voice) repeaters are a notable exception with the Big Box on the Hill retransmitting our radio signal. For decades now, FM repeaters have represented an infrastructure that individual hams and (more often) radio clubs put in place for use by the local ham community. There is a trend towards more infrastructure dependency in ham radio as repeaters are linked via the internet via IRLP, EchoLink and other systems.  (Some hams completely reject any kind of radio activity that relies on established infrastructure, often claiming that it is irrational, unethical or just plain wrong.)

One interesting area that is growing in popularity is the use of hotspots (low power access points) for the digital voice modes (D-STAR, DMR, Fusion, etc.) In this use model, the ham connects a hotspot to their internet connection and talks to anyone on the relevant ham network while walking around the house with a handheld transceiver. See the Brandmeister web site to see the extend of this activity. It strikes me that this is the same “small cell” trend that the mobile wireless providers are following. You want good handheld coverage? Stick a hotspot in your house.

Looking at ham radio and broadband communications, I summarize it like this:

• The vast majority of ham radio activity is narrowband oriented, for reasons described above.
• There is some interesting ham radio work being done with broadband systems, mostly on 2.4 GHz and 5.8 GHz.
• Commercially available broadband technology (LTE, 5G, and beyond) will continue to increase total network bandwidth and performance increasing the difference between commercial broadband and narrowband ham radio.

Implications

The reason for writing this article is that the amateur radio community needs to recognize and understand this increasing bandwidth gap. We like to talk about the cool and exciting stuff we do with wireless communications but we need to also appreciate how this is perceived by someone with an LTE phone in their pocket.  Just communicating with someone at a distance is no longer novel. After all, Amateur Radio is Not for Talking.

What do I conclude about this? Here’s a few options:

1. Don’t worry. We are all about narrowband and that’s good enough. This attitude might be sufficient as there are tons of fun stuff to do in this narrowband world. In terms of ham radio’s future, this implies that we need to expose newcomers to narrowband radio fun. We’ll need to get better at talking about how amateur radio makes sense in this broadband world.

2. Embrace commercially available broadband. Use it where it makes sense. This approach means that Part 97 remains mostly narrowband but we can make use of the ever-improving wired and wireless network infrastructure that is available to us.

3. Develop Part 97 ham radio broadband. I am initially a bit skeptical of this idea. How the heck does ham radio compete with the billions of dollars Verizon, AT&T and others poor into broadband wireless? But that may not be the point.  Once again, I fall back to the universal purpose of amateur radio: To Have Fun Messing Around with Radios.  Can we have fun building out a broadband network? Heck yeah, that sounds like an interesting challenge. Would it be useful? Maybe. Emergency communications might be an appropriate focus and some hams are already working on that. Create a network that operates independent from the commercial internet and make it as resilient as possible.

I think Option #3 is definitely worth considering. What do you think?

The next CLE event will be the special Christmas holiday event and includes two challenges! CLE 226 covers any NDB north of the Arctic Circle, while CLE 227 is a 'bearing' event, with each listener chosing a particular bearing from their receiving location and seeing how many beacons can be heard from states, provinces or countries through which that bearing slices! You will have plenty of time to listen as well, since the event runs from Monday 25th December to Tuesday 2nd January.

 


For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time (usually) on one small slice of the NDB spectrum.
 
Normally, December provides some excellent propagation but the planet continues to be bombarded with seemingly non-stop coronal hole streaming that can cause geomagnetic disturbances disruptive to MF propagation. However, often these 'disruptions' are not as dire as they first appear and MF propagation can remain robust or even be enhanced.

Listeners in Canada and the northern states as well as those in northern Europe will have a much better chance of logging the Arctic beacons. Most of these are large 'enroute' navigation markers with big antennas and plenty of erp ... they are heard very well.

A pdf list of all NDBs within the Arctic Circle can be downloaded from here.

If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.

For example, 'AA' in Fargo transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have a USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

From CLE organizer Brian Keyte, G3SIA, comes the usual 'heads-up':

Hello all

Time to tell you about our Holiday CLEs.
Yes – we have two of them, running at the same time, something we have often done in the Christmas – New Year period.

The Early Advice for both CLEs is described here, but we shall treat them quite separately after this.

==================================
CLE226 - SANTA’S BEACONS

We'll be sharing Santa's attempts to use the NDBs north of the Arctic Circle (Latitude N67 degrees) as he navigates his weary reindeer on the last stages of their long flights back home.

Please tell us of any normal NDBs north of the Arctic Circle that you manage to log.

Days: Monday 25th December – Tuesday 2nd January
Times: Midday on 25th Dec to Midday on 2nd Jan, your local time
QRG: Normal LF/MF frequencies
Target: NDBs within the Arctic Circle, north of Latitude 67 degrees

That is similar to what we did way back in Holiday CLE059 (Christmas 2004).

There are about 130 qualifying ‘active’ NDBs currently recorded in RWW.

(You can see the old results from CLE059 in the CLE Archives Section,
http://www.ndblist.info/cledata/CLE59santa.pdf  It only ran for 24 hours after midday on Christmas Day).

We do apologise to the listeners who are too far south to hear anything. (The further north listeners often miss out in normal CLEs, especially in the summertime when there is very little sky wave propagation for them).

The Final Details for the Santa CLE, CLE226, will follow in a few days.

===================================
CLE227 - BEARINGS CLE

Like CLE226, this is also a re-run, something that was very much enjoyed over 10 years ago - as CLE092 during a weekend in early June 2007.

Days: Monday 25th December – Tuesday 2nd January
Times: Midday on 25th Dec to Midday on 2nd Jan, your local time
QRG: Normal LF/MF frequencies
Target: Up to 10 NDBs in each Radio Country in your chosen direction

You choose a line in any one direction from you. Then try to log 'normal' NDBs in each of the radio countries crossed by that line - not more than 10 NDBs from each country.
Your line can be at any bearing of your choice - e.g. 123 degrees but NOT including the opposite direction (303 degrees).

Preferably use a Great Circle map to choose your line and to see which radio countries it cuts (a country is included if any part of it is crossed).

Remember that each USA and Australian State and each Canadian Province is a separate Radio Country. See http://www.ndblist.info/ndbinfo/countrylist.pdf

(If your line crosses the sea, any platforms roughly in that direction would also qualify as a radio country for the CLE).

The event will give you an opportunity to plan your own tactics. You could:

Try out a directional aerial
Include a favourite country or countries
Listen for NDBs which mostly have your favourite offset
Concentrate either on DX or more local reception
Exclude signals from the direction of your worst QRN
- any or all of those things, and more.

The aim is not to try and include as many countries or as many NDBs as possible, though you could do that if you wanted to!

TO CHOOSE YOUR BEARING, for non-dx loggings you could use an ordinary map (Mercator projection), especially if your location is near to its middle.

Better would be a Great Circle map centred on your location - you should find that https://ns6t.net/azimuth/azimuth.html is good and very easy to download and use. Just put in your location (e.g. Locator), choose a distance and click on ‘Create Map’. It misses out smaller countries, but reference also to a ‘normal’ map should cater for that.

Perhaps ideal would be Google Earth if you can download that (it is a powerful program for lots of purposes). Click on its Ruler icon and draw a line with the mouse. It tells you distance and Bearing ('Heading'). (Feel free to tell us about any other suitable Great Circle programs)

I can highly recommend the ns6t map generator as it produces a very nice great circle map, shown below for my location on Mayne Island.

courtesy: https://ns6t.net/azimuth/azimuth.html

I have yet to decide which bearing I will choose but 81 degrees looks promising from here as it cuts across BC, Alberta, Saskatchewan, Manitoba and Ontario while catching the northern edges of Minnesota and North Dakota.

(If you wish you could use any one remote receiver for your loggings,
stating the location and owner – and with their permission if required.
A remote listener may NOT also use another receiver, local or remote,
to make further loggings for the same CLE.

These listening events serve several purposes. They:

• determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date

• determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range

• will indicate the state of propagation conditions at the various participant locations

• will give you an indication of how well your LF/MF receiving system is working

• give participants a fun yet challenging activity to keep their listening skills honed

Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event. If you are a member of the ndblist Group, results will also be e-mailed and posted there.

The very active Yahoo ndblist Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

You need not be an ndblist member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

'First-time' logs are always VERY welcome!

Reports may be sent to the ndblist or e-mailed to either myself or CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above.

Please ... give the Holiday CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

Have fun and Happy Holidays to everyone.

Our Amateur Radio and the Maker Community post defined our stance that the future of ham radio is in experimentation and learning. This post builds upon that cornerstone article by outlining why you should even bother getting an amateur radio license. I won’t make points around the ability to talk around the world or independence from infrastructure that are often touted as benefits of ham radio. Instead, I will highlight why as a hardware designer and a software developer having your amateur radio license is a ticket to designing more interesting, useful, and complex projects.

The Federal Communications Commission provided US citizens with an amazing opportunity to experiment with and develop innovative technology when creating Part 97. You should take advantage of this opportunity. Let’s take a closer look at it!

Part 97, Part 15, and Part 18 (ISM)

We’ve seen these terms thrown around with little explanation. Often, they are taken at face value when you come across a transceiver on Adafruit or Sparkfun. In-reality there are very specific reasons a radio may be one or the other and in most-cases not requiring a license is preferred by manufacturers. That’s why Adafruit and Sparkfun do not focus on selling ham radio transceivers. We on the other-hand tailor to radio amateurs. FaradayRF specifies right on our Starter Pack that you must be a licensed radio amateur to use Faraday.

Licensed Versus Unlicensed Spectrum Use

Before we dive into the regulations lets take a moment to talk about the use-cases of each type of radio. We should be careful to directly compare radios such as Faraday which require an individual license against radios such as the Sparkfun RFM69 Breakout as they are aimed at very different use-cases.

Unlicensed radios operating under Part 15 let you do essentially whatever you want as long as you don’t change the manufactured device. There is no requirement to identify who you are and you can encrypt all your communications. Broadcasting is even allowed. Projects looking to connect to WiFi or Cellular networks will absolutely want to be encrypted so they should use these radios. However, as a hardware designer and software developer you’re not allowed to modify the radio or run higher power. Additionally, you’re at the whim of politics and interpretation as seen in the FCC firmware lock-down saga which is still a problem but has been alleviated because some manufacturers are taking a small stand.

Licensed radios operating under Part 97 on the contrary allow you to modify the hardware, firmware, and software to your hearts content. Most operating modes on most bands even allow you to push out 1500W to the antenna (not including antenna gain!) which is honestly just crazy amounts of power. Since most amateur bands give radio amateurs primary or at least privileged use of RF spectrum other users have to accept if you interfere and radio amateurs can also legally challenge interference against unlicensed users if necessary. There are many cases where this power has been helpful and one of the most notable cases is the ARRL and Broadband over Power Lines clash.

While you cannot encrypt your communications the debate is out whether authentication is legal. Exploring authentication will prove to be a fun endeavor in the near future for ham radio. With the lack of encryption the amateur radio community has a completely different feel to it since they want to communicate with each other. Generally, you don’t want your neighbors on your WiFi router but with ham radio we actually want them to join in most of the time. This helps create a community of experimenters that I’m proud to have been a part of since 2004!

Being able to hack at your hardware, firmware, and software just because you passed the easiest amateur radio test to get your technician class ticket makes the effort worth it. Projects like Faraday encourage open communication, open experimentation, and active collaboration on projects that are higher power and longer range than most unlicensed offerings. Next we will explore the differences between the radio services but remember that your amateur radio license doesn’t stop you from using unlicensed radios. It gives you all the privileges aimed at experimentation which I’ve outlined and lasts a lifetime with simple renewals once every 10 years. It’s worth it.

ISM and Part 15 is the Same Thing Right?

No! This is a really easy mistake to make. The Part 18 Industrial, Scientific, and Medical (ISM) band radios are not allowed to be used for telecommunications. See §18.107(c) which defines ISM equipment as “Equipment or appliances designed to generate and use locally RF energy for industrial, scientific, medical, domestic or similar purposes, excluding applications in the field of telecommunication“. The ISM bands provide areas of RF spectrum where unlicensed transmissions can occur that are often dirty, broadband, and sporadic. If you’re going to have these types of transmitters emit RF and they generally only need to transmit then grouping them together makes sense.

FCC Part 15 addresses the telecommunications gap for unlicensed use. Part §15.1(a) classifies what types of devices fall under it “This part sets out the regulations under which an intentional, unintentional, or incidental radiator may be operated without an individual license“. The last part about operating without an individual license is the most important statement. If you do not assume the operator is technically skilled enough to understand proper operation then it’s up to the manufacture to make sure the electronics are compliant as marketed and shipped to the consumer. This makes sense due to the FCC having no ability to determine whether you’re skilled enough to operate legally as a general consumer.

Part 15 Radios Using the ISM Bands

Many wireless solutions for makers and experimenters often operate in the ISM bands. This falls under Part §15.247which defines operation on 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz. These bands are three really popular ISM bands with the latter two best known for IEEE 802.11 WiFi use. Even the CC430F6137 used in Faraday is aimed directly at operating under Part 15 on the 902-928 MHz ISM band, that’s why we chose it! There is also a very good reason for manufacturers using ISM bands for unlicensed communications under §15.247. Most Part 18 users who can file complaints against part §15.247 devices do not even attempt to receive in the ISM band. In other words, the lights are on but no one is home.

ISM use is generally used for one-way transmissions such as microwave ovens, medical heating therapy, and IC wafer manufacturing (creating plasma with RF). Most CFL lightbulbs are Part 18 due to the RF energy needed to excite the mercury vapor inside them! Therefore any Part §15.247 radio transmitting on these bands is extremely unlikely to cause any noticeable interference to an ISM device. Secondly, when you as an experimenter use these radios and modify them (however legal that actually is) it will be much more likely that any interference which results will go unnoticed.

So What About Amateur Radio?

The FCC Part 97 rules define what Amateur Radio is. Amateur radio is justified in §97.1 using five points, of which the fourth is our favorite “Expansion of the existing reservoir within the amateur radio service of trained operators, technicians, and electronics experts“. This right here is why we love amateur radio! One of the founding principles of the hobby was to spur innovation.

I will highlight why as a hardware designer and software developer having your amateur radio license is a ticket to design more interesting, useful, and complex projects

You need not look much further before finding §97.103 which clearly states “The station licensee is responsible for the proper operation of the station in accordance with the FCC Rules“. Unlike general consumers the FCC trusts you, a licensed radio amateur, as being capable of properly operating your station. In the more than 100 years of ham radio this expectation of trust and self-regulation has worked out far better than one would initially assume.

So far we’ve only showed you why earning the FCC’s trust is beneficial. Now we will show you what that trust gets you! That’s where §97.303 comes in. Faraday operates on the 33 cm ham band (902-928MHz) as a Part 97 device. More importantly §97.303(b) and §97.303(e) define how we as radio amateurs can use the 33 cm band.

(b) Amateur stations transmitting in the 70 cm band, the 33 cm band, the 23 cm band, the 9 cm band, the 5 cm band, the 3 cm band, or the 24.05-24.25 GHz segment must not cause harmful interference to, and must accept interference from, stations authorized by the United States Government in the radiolocation service.

(e) Amateur stations receiving in the 33 cm band, the 2400-2450 MHz segment, the 5.725-5.875 GHz segment, the 1.2 cm band, the 2.5 mm band, or the 244-246 GHz segment must accept interference from industrial, scientific, and medical (ISM) equipment.

As a maker interested in amateur radio these are profound opportunities. You are allowed to transmit unless you cause interference to the “United States Government in the radiolocation service” and you must receive interference from ISM band devices since we are secondary users of this band. As I stated earlier you are not allowed to interfere with ISM devices but since almost no ISM devices have receivers, interfering would prove very difficult to do in practice.

The requirement not to interfere with the United States Government sounds scary but KB9MWR has a great web-page talking about just what these uses are. In summary, you have little chance of actually being required to stop transmitting due to interfering with government radiolocation services. This leaves the requirement of accepting ISM interference as the only real downside to using the ISM band for ham applications. As long as you are OK with some extra RF noise the 33cm band is wide open for ham radio.

The ISM Bands are Junk!

So, ISM bands are largely relegated to “junk” use and radio amateurs must accept interference from ISM devices when using them. This doesn’t mean you have to stop using them when interfered with, it means you have no legal ability to complain about an ISM device bugging you. This is true for Part 15 devices as well and yet we use ISM bands for communications all the time with WiFi on 2.4 GHz and 5 GHz. Most garage door openers, wireless headphones, and baby monitors use ISM bands as well. For example, sometimes our microwaves cause WiFi to slow down but most of the time we never notice.

Amateurs have often denounced the 33 cm band (902-928MHz) as junk due to the noise heard on it. This however is antiquated advice. Digital transmissions are much less susceptible to observation of noise than analog transmissions. Using 33 cm for FM voice maybe be irritating but digital users may never notice the noise.

This is why Faraday is pushing the use of 33 cm for hams. Combined with the incredible privileges of a ham radio license, Faraday is set to be revolutionary for the 33 cm ham band. We want you to start experimenting, start learning, and start using amateur privileges on the 33 cm ham band.

Go Earn Your Amateur Radio License… Now!

We’ve convinced you that being a radio amateur is pretty badass. We know it is, too. As a designer or programmer you will find it easy to “earn your ticket” with a little study. The opportunities to work on interesting projects with increased functionality, range, and reliability are a few of many reasons an amateur radio license kicks-ass. Using your Part 97 license gives you the right to build more powerful, more complex, and more useful projects than possible using unlicensed radios.

To use Faraday or any other amateur radio transceiver on the 33 cm band you only need a Technician class license in the United States. This is the easiest license to get and requires no Morse Code skills. The AmateurRadio subreddit has an awesome wiki page on what you need to do to become licensed. Check it out, get your license, and push the boundaries of RF experimentation with us.

We are excited to see you get licensed! If we’ve convinced you to get your license please let us know. We’d also love to hear your thoughts on the benefits and drawbacks to using ISM, Part 15, and Part 97 devices here in the United States. Leave us your thoughts in a comment below!

We are simply conversing about published documentation regarding ISM, Part 15, and Part 97 regulations and are not lawyers! Do not take this article as legal advice.
