Dave K1SWL and I spent a couple of hours at Winslow State Park at the base of Mt. Kearsarge this afternoon. It was 57F and really beautiful.

A nearby parking area serves as the trail-head for several hiking paths up the mountain. There are a few picnic tables in a small field nearby and we set up there.

Dave wanted to try out a new half wave wire and matching circuit he’d built. So he tossed a wire into a maple tree and pulled up the antenna. He used his KX3. He was already making a QSO on 20 meters as I was setting up.

A few feet away, I pulled up the 3-band LNR end fed wire. I supported it in the middle and used it as an inverted Vee. I had the 3-band MTR by KD1JV powered by 8 AA cells. The output is close to 3 watts. I made a quick contact with Ron K4UY in Alabama and received a 569 report.

As I finished I heard Dave working another station… VO1DD in Hearts Delight, Newfoundland. I called over and Dave gave me the frequency. When Dave signed, I gave the Newfoundland station a call. Doug gave me a 599 and we chatted for a minute. That was super.

In the meantime Dave was working a station in California. I never got the call, but had time to snap a quick photo of Dave before they signed.

I switched to 40 meters and happened to hear Joe N2CX calling CQ from an NPOTA site… the Clara Barton National Historic Site in Maryland. Fantastic! I gave Joe a call and received a 559. Joe left 40 meters before Dave could finish his California QSO, so Dave didn’t catch Joe this time around.

Now the sun started dipping below the trees and our picnic tables were in shade. Right away we began to feel the chill and packed up. It’s unlikely we’ll get another day this warm before the snow falls. Thank goodness we were able to take advantage of the opportunity.

For the past few months I have been having a love hate relationship with a Raspberry Pi Model B and Direwolf. The software runs perfectly well on my Pi3 but makes my other Pi fall over relatively easily. When this is at home it is no problem at all. I just reset and it will restart the software but the trouble is it has been at the clubs QTH. Ok I can log in remotely and deal with it but when it refuses to connect to the internet it becomes a pain. So I was looking for alternative solutions.

I came across the Dorji DRA818v module a little while ago and though that would work. It is a simple module that just needs a PCB and some connections to the Pi. But hang on, there are PCB’s you can already buy. But they don’t have filtering. Now hang on again there are those with filtering too. Now that looks good. Then hanging on for a third time the Sainsonic AVRT7 does it all simply!

So, now there are a bunch of choices for the same module. I’ve ordered a AVRT7 and around 30+ working days later I should receive the new toy.

There are a few warnings about counterfeit Prolific chips and trouble programming. I can see some frustrating times ahead but I’ve never been one to shy away from a challenge. I just hope it’ll be one that can be beaten. I will also get myself a SV1AFN pcb when I get around to it for home / experimental use. Just don’t tell Mrs g7kse!

Whilst we are on the subject I am really impressed with Direwolf. WB2OSZ has produced a really great bit f software that is easy to install on that Raspberry Pi and RTL Dongle you bought that you’re not using. The world can only get better with loads of iGates

APRS-K2
It’s long overdue, but there’s finally a TRRS/APRS cable available for radios using a standard Kenwood style K2 connector.

I’ve been wanting to get involved with APRS for a while now, and this made it extremely easy.

APRS-K2 interface cable
The APRS-K2 cable allows you to interface your handheld transceiver with your existing mobile device, including. iPhone, iPad, and Android.

One end of the cable uses the Kenwood style K2 connector, while the opposite end is terminated with a TRRS connector. Also included with the APRS-K2 is a Reverse Adapter to insure compatibility with all devices. This adapter allows cable to connect to earlier 3.5MM TRRS standards, such as Nokia.

App Driven
The APRS-K2 cable uses a virtual TNC found in several apps, such as APRSDroid, APRS.fi, and Pocket Packet. Plug in the cable, turn on the VOX, and you’re pretty much set to go.

Product Description
BTECH APRS-K2 TRRS / APRS Cable A simple way to start using APRS by using devices you already own. The BTECH APRS-K2 Cable will quickly connect your radio to APRS by using virtual TNC (app driven) on your tablet or device. The APRS-K2 cable is built with a custom circuit board that will automatically adjust the audio for clear packet transmissions with minimal adjustment; along with protecting your devices from strong over modulated signals.

Along with allowing APRS functionality the APRS-K2 cable can provide a simple interface gateway to allow several features to your radio!

Easily record radio conversations:
By connecting the APRS-K2 cable between your radio and any recording (line-in) device.

Use the APRS-K2 cable as a Mic In Connector:
Set up VOX on your radio to accept any form of incoming audio – such as a Push-to-talk application on a Phone – or a Line-out application from your computer.

Use the APRS-K2 cable to push transmissions over a speaker system:
Easily play audio over a intercom or speaker system from your handheld.

With a backup radio and your own ingenuity, the APRS-K2 cable can serve as an interface for a variety of applications for any amateur. Compatible with Kenwood K2 Accessory Slot Radios (such as BaoFeng, BTECH, Wouxun, TYT) Compatible with all phones, tablets, and computers with 3.5MM Audio In/Out Ports

Includes:
APRS-K2 Cable
Reverse Connector Adapter
Quick Start Guide

Conclusion:
The cable comes with a simple one page instruction sheet which should have you up and running in about 10 minutes after the appropriate app is loaded.
–  Plug in the cable
–  Set your handhelds volume control
–  Turn on the VOX
–  Set your handheld to 144.390 (US)
–  Activate the app

That’s all it takes. If you’ve been considering building an APRS cable, you might find this an easy Plus and Play alternative.

The APRS-K2 can be ordered from   Amazon, or if outside the US, you can go to their website and contact them directly.   Baofeng Tech

Too many toys, too little time.

Good afternoon from VE3WDM, it's a Sunday afternoon and the weather is sunny with a high of +10C. It was a nice day for a walk which my wife and I did mid afternoon. Once home it was time to setup for the software for the up coming CQ WW CW contest. There were some bugs I had to workout with the software and I did without issue. Then there were some minor issues that I am just going to forget about for now. For example I have no idea why my Winkeyer USB when N1MM+ is running will allow me to only control the CW speed but for some reason I just can't seem to communicate with the Winkeyer to setup and execute macros?? I'm not going to sweat it as in the past I have found that once you start monkeying around with the different pieces of software things that did not work now work...........BUT things that did work DONT!
While setting things up I did have the K3 on and the P3 waterfall viewing the 20m band. I did notice TL8AO and the HUGE pileup that was "UP" 2 KHz on the band. Funny thing as I was listening I did find an op more often than not calling on TL8AO's calling freq and not splitting "UP" On the waterfall of the P3 I did notice a new strong CW signal appear so I pointed and clicked over to it. It was HI3Y in the Dominican calling CQ and "UP". I listened as I setup the split and he seemed to be calling without a pileup. I threw my call out there and he came back to me with a report. He was in the books just that easy...now only if my 5 watts could break the pileup with TL8AO that fast! Time to start dinner now.......Tenderloin steak on the BBQ, mini potatoes on the BBQ with butter and rosemary and finally butternut squash........yum!
