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.
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.
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
Reverse Connector Adapter
Quick Start Guide
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.
Too many toys, too little time.

Some exciting news wandered into my inbox this past week concerning a handheld radio driven by the Android operating system. The RFinder H1 is an FM plus DMR radio to be released at the end of this month. Click to enlarge the photo to the left to get a better view. I had proposed a similar concept back in 2012: The Android HT, so this radio immediately grabbed my attention.
Details are still a bit thin on the RFinder H1 (pronounced “Ar Finder H 1”) but this video gives you a glimpse of its operation. The 70cm band radio apparently also supports GSM and 4G/LTE mobile phone formats.
There are a few other YouTube videos available, one of which emphasizes the easy programming of the radio using the RFinder online repeater directory. This makes perfect sense and is a great example of the power of a connected device. This feature would be very handy for programming up FM repeaters on the fly and outstanding for dealing with the complexity of DMR settings.
The RFinder H1 includes DMR capability, something I wasn’t thinking of back in 2012. That also makes perfect sense…embracing the growing amateur radio format that is based on industry standards.
Very cool development. What do you think?
