Weekend plans go semi awry.
September 18th, 2016 | 
Author: I had planned on two Amateur Radio activities this weekend. I almost ended up going 0 for 2, but ended up batting .500 instead.
My first planned activity was to participate in the NJ QSO Party on Saturday. The work party that I attended at the Middlesex County Office of Emergency Management went longer than I anticipated. I'm glad we got the work done that we did, though, as it was important that it got done before the Simulated Emergency test in October. When I got home, there was still plenty of time to participate in the contest - no doubt. Other chores had to be taken care of first, though; and I made sure I got those done. End result? One very tired W2LJ and no NJQP on Saturday.
After dinner, I sat down with the tablet and saw on the ARRL NPOTA Facebook page that Peter K0BAK was doing a sweep of NJ activations this weekend, including AA17, the New Jersey Coastal Heritage Trail. My heart sank a bit because he's such a superb operator and activator - does AA17 really need to be activated twice the same day? And if you had the chance to work either me or Peter .... heck, even I'd rather work Peter than me !!!

And if you had the chance to work either me or Peter .... heck, even I'd rather work Peter than me !!!
When I went to bed last night, I was really iffy about making the effort. The weather was supposed to be suspect but I decided to sleep on it, thinking perhaps that maybe it might be better to wait for another weekend.
Sunday morning dawned muggy and overcast. Not exactly the greatest of weather conditions. But then the thought occurred to me that K0BAK normally does most of his operating on SSB, and mine was to be CW; so I decided to throw caution to the wind and decided to go to Cheesequake State Park, anyway.
I left the house a little after 9:00 AM and got to the park just around 9:30 AM. I found the Spring Hill Picnic Grounds to be deserted, save for a few parked cars. The occupants of those cars were all going off on hikes as the lot also served as the starting point for one of the park's many trailheads. With the picnic tables all to myself, I set up the PAR ENDFEDZ 40/20/10. The line went up over a 60 foot tree with ease thanks to my trusty Joplin MO ARC Antenna Launcher. I literally had the antenna up within minutes. I've had enough practice with the launcher to now get a good shot on the first try, at least 90% of the time.
The setup was the usual, KX3 to antenna, the Power Werk deep cycle battery, the Palm Micro paddles and a set of ear buds. The ear buds turned to be a life saver, as the picnic area turned out to be pretty gosh darn close to the Garden State Parkway, and there was lots of highway noise. In some cases, there were also some ignition noise moments. I thought I was far enough away where that wouldn't be a concern; but there must be a few vehicles out there that are close to being spark gap transmitters!
I got on the air at 1400 UTC, calling "CQ NPOTA" on 40 Meters at 7.034 MHz, and had my first QSO with W3JRR at 1415 UTC. I stayed on 40 Meters for about 45 minutes before taking a break to stretch my legs and to use the rest facilities. Thank the Lord they were open! I came back to the ear buds, and I could have sworn that I heard "BBO". I thought that was my good friend W3BBO looking for me; as I spotted myself on the Cluster. I called him a few times and heard no come back; so I decided to move on up to 20 Meters.
20 Meters turned out to be the better band. My farthest DX QSOs happened there with S58AL in Slovenia and ON4RO in Belgium. I also ended up working Arizona and Washington state on 20 Meters. So even though I made it to Europe, this is where the Reverse Beacon Network picked me up:
Just before 1600 UTC, I was visited by a Park Ranger who came to put up a sign showing that the picnic grounds had been reserved by a Baptist Church group for a BBQ. It was booked for 1:00 PM local or 1700 UTC. I decided to pack it in, anyway. My original plan was to put in about two hours, so that I wouldn't be away from the family for the entire day; and I put in my two hours, so I was happy.
The highlights of the day were working Kay Craigie N3KN, Dave Benson K1SWL of Small Wonder Labs and Rockmite fame, as well as Paul Signorelli W0RW, of QRP and Paraset Pedestrian Mobile fame. It's always cool when you go on an outing like this and hear the call signs of people you regard as friends. Not to say that ALL of you aren't friends ........ but you know what I mean!
37 QSOs later, my activation of AA17 was in the books for the day. I still hope to join up with Dave Hackett KD2FSI to activate the Pine Barrens and the Delaware Water Gap and the Appalachian Trail before NPOTA comes to a close - so stay tuned!

New Jersey QSO Party this weekend!
Not one of the biggies, by any means, but the Burlington County Amateur Radio Club has been working their tails off to get the NJ QSO Party back in the mainstream. For years, there was a lack of participation; but due to their diligence, it seems to be making a comeback.
For all the details, please visit: http://www.k2td-bcrc.org/k2td_index.html
I have a Middlesex County OEM work detail to attend in the morning. I hope to get some operating time in sometime during the afternoon. Maybe out on the patio table with the mag loop?

Haven’t said this in a while
but "Thank You" to all of you who read this blog. It would be foolish and time wasting for me to do this if you weren't out there. From the e-mails, photos and comments I receive, I know that you all are, indeed, out there. Again, thank you so very much.
On the QRP side of things, I see from an e-mail by Doug KI6DS to the QRP-L list that the QRPGuys have a new kit offering out. The following is their description:
The QRPGuys Multi-Tuner is a Z-match design that will match a wide range of coax fed, long wire, and balanced line antennas, like high-impedance, low-loss UHF twinlead or ladder line for 40m-10m.
It uses the N7VE integral led swr indicator with an absorptive bridge to protect your final transistors from a poor match. In the TUNE position, you cannot damage your transmitter caused by a high SWR. It is looking at a 50 ohm load and the LED is indicating only the reflected power. At full brilliance your SWR is 4:1 or greater, at half brilliance your SWR is approximately 2:1, and the LED will completely extinguish at 1:1.
Rated for 5 watts continuous, 10 watts intermittant, weighs (4.3 oz.) and comes with female BNC connectors for the input/output, with S.S. hardware for the long wire and balanced line connections. There is no point to point wiring. All connections are accomplished by mounting the components on the PCB. This kit can be built in a couple of hours. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 3.
For more information, and ordering, you can go to http://www.qrpguys.com/
I don't have to tell you (but will, anyway) how important it is for us to patronize concerns like QRPGuys, QRPMe, QRP Kits, SOTA Beams, and the numerous other QRP vendors around the world that are out there. Blogging is my way to give a bit back to the hobby. Offering kits is the way these guys give back to the hobby. Yeah, they are there to make a buck or two; but they're definitely not in this with visions of becoming the next Elecraft. You keep me "in business' by reading; and we keep them in business (and as a result, keep the QRP hobby alive) by purchasing their wares.

Review – BTech UV-5X3 TriBand Handheld
by John ‘Miklor‘
.
.
UV-5X3Although the case design is familiar, the radio inside is not. BTech has recently introduced the new UV-5X3 to the US Ham Radio market. This radio is a true triband transceiver with internal filters specifically configured for triband operation.The firmware in this radio has been reworked to include several new features not found in similar appearing radios.
.
In the Box
Included with the radio are the:
– 1500mAh Li-Ion Battery **
– 85 page User Guide – English
– Charger base & AC adapter
– Hand strap
– Belt clip
– PTT Earpiece / Microphone
– Antenna (1) – VHF / UHF 6 3/4″ (17cm) A-V85
– Antenna (2) – 220 MHz 6 1/4″ (15.5cm)
.
** This is the identical battery that is commonly mislabeled as 1800mAh on some handhelds.
.
Tri-Band – VHF 220 UHF
The UV-5X3 was specifically designed as a Tri-Band transceiver. The internal filtering allows not only the traditional VHF and UHF frequencies, but also includes the 222-225 MHz Ham band for the US.

. 
Case Design
The UV-5X3 has the traditional case design, which allows me to use my high capacity BL-5L 3800mAh battery with no alteration to the base. Accessories such as my mobile battery eliminator, Spkr/Micr, etc. are fully compatible.
.
Transmitter
The frequency range is VHF 130-176 / 222-225 / UHF 400-480 MHz, supporting both Wide and Narrowband with 2.5kHz steps.The radio’s filtering scheme allows for full power on all bands. My OTA audio reports have been clean with clear with mellow audio. Power levels are respectable using a Bird VHF/UHF Termaline.

DTMF / IRLP Access
Something new also appearing on this model is a DTMF gain adjustment, allowing me to adjust the DTMF audio to the transmitter to a comfortable level for both repeater control and IRLP access.
.
Tone Burst
If you are in a area that requires tone burst for repeater or network access, the 1000Hz, 1450Hz, 1750Hz, and 2000Hz burst are accessible by pressing the PTT along with one of the four pre-assigned keypad keys.

.
Receiver
The receiver sensitivity is excellent, and the audio quality is clear, loud, and undistorted. Along with the 3 TX/RX bands, the receiver also includes the traditional commercial FM radio band. (65MHz-108MHz)
.
Tone Scanning – The receiver also has the ability to identify the tone of a repeater being transmitted by a received signal.

.
Scan Add / Delete
This feature gives me the ability to add / delete channels from the scanning list using the keypad. No longer a software only function. The more I can do from the keypad, the better I like it.

Scanning
A Long Press of the [*SCN] button will start the scanning process.Channel Mode – When scanning with the Display Sync set to ON, the upper and lower display will scan together. This is explained below under Display Synchronization.Frequency Mode – When entering Scan, the image below will appear on the screen. Enter the first 3 digits set the range start, the second 3 digits sets the stop.
Example: Entering 146 : 146
Start the scan range at 146.000
Ends the scan range at 146.999

Ends the scan range at 146.999
.
AntennaI found two antennas included with the radio. One was the standard upgraded A-V85 antenna, and a slightly shorter one for the 220MHz band.
Antenna (1) – VHF / UHF 6 3/4″ (17cm) A-V85
Antenna (2) – 220 MHz 6 1/4″ (15.5cm)
The separate antenna specifically tuned for 220 MHz is a great addition. The SWR shows 1.3 which is excellent. No compromise. I labeled my 220 antenna, as they are very close in appearance.
.Display
The radio has a tri-color display, allowing the color options of the blue, orange and purple. The LCD can be formatted in either of three formats. Choices are Frequency, Channel number, or up to 6 Alpha Characters.Display Synchronization
The UV-5X3 supports display syncing, which gives ability to track both the upper and lower LCD. I keep mine set to display the channel name in display A, and the frequency in display B. When you change the channel, both the upper and lower displays move together.
.Programming
Manual programming is pretty straight forward once you enter a few channels. A programming guide can be found at Manual Programming with a Menu Definition summary available at Menu Definitions.
.
Software
The software support for the UV-5X3 can be found in the Latest Daily Build of CHIRP. There are a few new options that will be added to the 5X3 in the near future. One is the ability to Stun, Kill, Revive. This gives you the ability to disable your radio remotely.

.
3rd Generation Chipset
The new chipset (RDA1846S and RDA5802N) provides reduced AGC switching noise and a low-IF digital audio processor for improved sound quality.

.
Programming Cable
The programming cable requires a traditional two pin Baofeng / Kenwood style. There are several cable available. The generic cables may require special drivers, due to the use of cloned chips. For Plug and Play, a cable using an FTDI chip is recommended.
Conclusion
The UV-5X3 firmware has obviously been reworked to include:
– Tri-Band Support: VHF/1.25M/UHF
– D-ANI (Display incoming DTMF Tones)
– Synchronized Displays
– DTMF audio gain level adjustment
– Add / Remove Channels from Scanning list via keypad (LCD Dot Indication)
– On the Fly scanning by Frequency Range
– 4 Tone Burst options
– Remote Stun, Kill, Revive

.
It appears that BTech has once again managed to stay one step ahead of the curve. With the 220 MHz ham band operation back on the rise in the US, this radio hit the market at the right time. Even if 220 isn’t popular in your area, the additional new features still give it an edge over the traditional dual band series.
