Walt/W0CP had recommended this Summits On The Air (SOTA) summit (W0C/SP-076) to me a while ago. Somehow it had escaped my attention, probably because it’s an unnamed peak and not that well known. Joyce/K0JJW and I decided to give it a try today and it turned out great.

We followed Walt’s directions on the SOTA website, using the southern route. We were pleasantly surprised to find a pretty good trail most of the way to the summit. There were a few spots with downed timber, where people have diverted around the logs, but generally the trail was easy to follow. The trail is not shown on many maps, including the USFS San Isabel Forest map. Thus, I was expecting considerable bushwacking to get to the summit.

The route to the trailhead is via FS Road 273, easily accessible from Highway 285 south of Buena Vista and north of Salida. See the San Isabel National Forest map for orientation. The road is narrow in spots. Our Jeep Wrangler fit OK but a wider vehicle would get to deal with the brush on both sides of the road.  The road is easy 4WD and should be passable with a high-clearance 2WD vehicle. The road had some snow on it (Nov 25, 2017) and with a few more snowstorms may not be passable.

The road continues a little further than indicated on our topo map but it is obvious when it ends. After that, the road turns into a nice trail (our route shown on the map above). The trail has a few broad switchbacks that made for easy hiking. When we got near the summit, the trail was covered by many small snow drifts, so we opted to go off trail and just head for the summit. So our last quarter mile or so is probably not optimal for summer hiking. There are several mines at or near the top of the mountain.

We had quite a variety of radios with us, for 2m, 1.25m, 70 cm and 23 cm, FM only. We started on the workhorse band (2m FM) with the 25W Tytera radio and a vertical half-wave antenna. It seems that someone (me) left the 3-element 2m yagi antenna at home. We quickly made contacts with KD0MRC, W0BV, KD0VHD, KE0DMT and KL7GLK on 2m and/or 70 cm. I used my Alinco 222 MHz handheld to work KD0MRC on 223.5 MHz, which is apparently the first 222 MHz SOTA contact in Colorado. (Yeah, not a popular band.)

For the most part, it was pleasant on the summit, about 40 degrees F, but it got cold whenever the wind picked up. Without the wind, it was great. With the wind, kind of cold.

This is a great hike and a great summit. Only a few people have activated it for SOTA, so I wanted to write it up for others to consider. We will definitely return to this one due to it’s excellent combination of easy accessibility, good trail and wonderful views.

The post Hidden Gem: W0C/SP-076 Unnamed SOTA Summit appeared first on The KØNR Radio Site.

For those of you who have dived into the crowded but fun pool of FT8 operation or one of the other Joe Taylor modes (such as JT65 or JT9) and are excited now about digital modes, here’s something you might enjoy, too.  Unlike those modes that allow you to make quick work of getting DX stations into your logbook, simply by exchanging callsigns, a signal report, and a grid square, there are other modes that offer keyboard-to-keyboard conversational QSO opportunities.

One such mode is known as Olivia and this mode offers keyboard-to-keyboard chatting for when you want to relax, and maybe make a friend.  Ham radio is the oldest electronic social networking infrastructure.

In 2005, SP9VRC, Pawel Jalocha, released to the world a mode that he developed starting in 2003 to overcome difficult radio signal propagation conditions on the shortwave (high-frequency, or HF) bands. By difficult, we are talking significant phase distortions and low signal-to-noise ratios (SNR) plus multipath propagation effects. The Olivia-modulated radio signals are decoded even when it is ten to fourteen dB below the noise floor.  That means that Olivia is decoded when the amplitude of the noise is slightly over three times that of the digital signal!

Olivia decodes well under other conditions that are a complex mix of atmospheric noise, signal fading (QSB), interference (QRM), polar flutter caused by a radio signal traversing a polar path. Olivia is even capable when the signal is affected by auroral conditions (including the Sporadic-E Auroral Mode, where signals are refracted off of the highly-energized E-region in which the Aurora is active).

Currently, the only other digital modes that match or exceed Olivia in their sensitivity are some of the modes designed by Joe Taylor as implemented in the WSJT programs, including FT8, JT65A, and JT65-HF–each of which are certainly limited in usage and definitely not able to provide true conversation capabilities.  Olivia is useful for emergency communications, unlike JT65A or the newly popular FT8.

Here is a demonstration of a two-way transmission using the Olivia digital mode on shortwave. I am in QSO (conversation) with KA5TPJ. There are two other Olivia QSOs just below our frequency. Just above us is a lot of FT8 activity. Below the two other Olivia QSOs are PSK31 QSOs. The band is active. Olivia is not dead!

The standard Olivia formats (shown as the number of tones/bandwidth in Hz) are 8/250, 8/500, 16/500, 8/1000, 16/1000, and 32/1000. Some even use 16/2000 for series emergency communication. The most commonly-used formats are 16/500, 8/500, and 8/250.  However, the  32/1000 and 16/1000 are popular in some areas of the world and on certain bands.

This can cause some confusion and problems with so many formats and so many other digital modes. After getting used to the sound and look of Olivia in the waterfall, though, it becomes easier to identify the format when you encounter it.  To aid in your detection of what mode is being used, there is a feature of many digital-mode software implementation suites: the RSID. The video, below, is a demonstration on how to set the Reed-Solomon Identification (RSID) feature in Ham Radio Deluxe’s Digital Master 780 module (HRD DM780).

I encourage ALL operators in any digital mode such as Olivia, set the RSID feature on as shown in this example.  In Fldigi, the RSID is the TXID and RXID (I believe).

Please make sure you are using the RSID (Reed Solomon Identification – RSID or TXID, RXID) option in your software.  RSID transmits a short burst at the start of your transmission which identifies the mode you are using.  When it does that, those amateur radio operators also using RSID while listening will be alerted by their software that you are transmitting in the specific mode (Olivia, hopefully), the settings (like 8/250), and where on the waterfall your transmission is located.  This might be a popup window and/or text on the receive text panel. When the operator clicks on that, the software moves the waterfall cursor right on top of the signal and changes the mode in the software. This will help you make more contacts!

+ NOTE 1:  MixW doesn’t have RSID features. Request it!

+ NOTE 2: A problem exists in the current paid version of HRD’s DM780: the DM780 RSID popup box to click does not work. HRD support is aware of the problem. You can still use the textual version that you can select in the settings so that it appears in the receive text areas. If you click the RSID link that comes across the text area, DM780 will tune to the reported signal, and change to the correct settings.

+ NOTE 3: some websites publish frequencies that are right on top of weak-signal FT8, JT65 and JT9 segments. Even if that is a matter of contention, follow the regulations and be kind: DO NOT QRM weak-signal QSOs! AGAIN: make sure that your signal does not cross into other sub-bands where weak-signal modes are active. For instance, do not have any part of your signal at x.074 or higher, as this is the sub-band for FT8, JT65A, and JT9.

Quick Reference: we in the active Olivia group suggest 8/250 as the starting settings when calling CQ on the USB dial frequency of 14.072 MHz with an offset of 700 Hz, on 20m–that translates to a CENTER frequency of 14.0729 MHz. On 40m, 7.072 MHz on the dial with an offset of 700 Hz (and again 8/250) which translates to a center frequency of 7.0729 MHz.

An example of the calling frequency on 20 meters with a center frequency of 14.0729 MHz, 8 tones, and a bandwidth of 250 Hz.

Also, do not quickly switch to other modes without calling CQ for at least a five-minute window. It is really horrid when people call CQ and change settings, modes, bandwidths, tones, every time they call CQ during the same session!

There are several key resources that we in the Olivia community are developing, to make it easier for you to enter into the great world of Olivia.  One is an active support e-mail group to which you can subscribe at https://groups.io/g/Olivia — a group containing topical areas of interest which can be filtered so that you are not flooded by email containing topics of which you are not interested.  It has a files section, as well, in which we will add helpful how-to instructions and so on.

Another resource is our Facebook group, at https://www.Facebook.com/groups/olivia.hf — also with a files area containing help files.  This group is a great resource for getting help from like-minded Olivia digital mode enthusiasts.

Some more eavesdropping on an Olivia QSO:

And, two more:

One last note: Olivia is NOT a weak-signal mode. There are no points won by barely making a contact. In the USA FCC regulations, you are directed to use only the power necessary to make the QSO.  Typically, with poor propagation, using Olivia with an output power of 100w is the minimum to establish a reliable circuit. You just cannot go beyond your rig’s duty cycle (don’t burn out the finals in your radio!). You also must be sure that you do not overdrive the audio chain into your radio. Be sure that you do not have RF coming back into your audio chain. Yes, 100 watts is acceptable. Don’t let anyone convince you otherwise. After all, think about RTTY.

Welcome to Olivia!  See you on the waterfall.

TSM Reviews: Yaesu FT-891 All-Mode HF+6 100-Watt Transceiver
By Mark Haverstock K8MSH

This month Mark takes a look at the Yaesu FT-891, one of the least expensive 100-watt, all-mode HF+6-meter radios on the market today. Mark finds that, “Its small size and remote head make it perfect for mobile/portable use, and its small footprint fits even on crowded desktops. The larger display is a welcome change, considerably more readable than the tiny ones on the FT-857D and FT-897D.” Mark also notes, “Those who own or have owned Yaesu radios will be used to the menu system, and will appreciate the attempts to provide easier access to some functions.” But that’s not all the 891 has going for it, as you’ll learn when Mark puts his 891on the air.

TSM Reviews: SpyVerter V2
By Bob Grove W8JHD

The earlier version of SpyVerter got a nod of approval from Bob Grove two years ago. But what would he say about this latest version? Spoiler alert! Bob says, “I’ve never changed my mind about the superiority of the Airspy spectrum-displaying receiver to its competitors. Now, with the addition of the previously-missing lower spectrum—virtually down to zero—this is a current leader in computer accessories for radio hobbyists.” In this month’s review he even tells how to use this device to monitor birds, animals and insects in the audio spectrum as well as the sounds of fish in the sea!

TSM’s Annual Scanner Buyer’s Guide
By Larry Van Horn N5FPW

The radio scanner world has been in flux since it began decades ago. And, while the number of manufacturers has shrunk over the years, the capabilities of these electronic marvels have kept pace with the changes. In this survey of all available scanners, Larry writes that, “bare bones, conventional analog-only scanners will run from just under $100. A good analog-only trunk-tracking scanner can be purchased for less than $200 (street price); however, if you need to monitor an APCO P25 Phase I digital trunked radio system, that price quickly jumps to around $400. Add in additional digital modes such as DMR and/or NXDN and APCO P25 Phase II systems and now you are looking at a sticker price north of $500 in most cases.” But, you may not need the latest technology where you live. Find out which scanner is best for your particular location.

Entry Level HF Transceiver Comparison
By Cory GB Sickles WA3UVV

Are you a Technician class amateur radio licensee, looking to explore what is available in HF transceivers in a price range that won’t break the bank? HF operation requires a little more commitment than VHF/UHF FM gear and, while you can easily pick up a high-quality monoband mobile for under $200 or a dual-band portable in the same price range, HF gear is going to run you a bit more. Considering all that you get in the deal though, it’s still reasonably priced. Cory takes a comparative look at what Alinco, Icom, Kenwood, and Yaesu have in the way of 100-watt, entry-level offerings, with a street price of less than $800. With the need for a 20A power supply and simple antenna, a “Kilobuck” budget should certainly get you on the air or perhaps even less.
