Compatible with Kenwood K1 Accessory Slot Radios (such as BaoFeng, BTECH, Kenwood, Wouxun, TYT)Compatible with all phones, tablets, and computers with 3.5MM Audio In/Out Ports Includes: APRS-K1 CableReverse Connector AdaptorQuick Start Guide Review: Great product - Works well thanks Review: Good cable hamstung by radio - 1. The cable is made well and no issues with the cable itself. 2. The cable's use is very limited by the radio if you want to do APRS doing both transmission and reception. If you want to do one or the other the cable works great. If you just want to be a beacon it works fine, if you want to just see what assets are around again the cable works fine. You just can do both. Here is the reason why The cable is audio only so you have to use VOX if you want to transmit. If you want to transmit put VOX on 2 and the radio will transmit fine. Warning be careful sending email or text via APRS. The receiving station will send back a confirmation but the Baofeng will not properly hear the confirmation and depending on your software it may try to send the message again. To get a Baofeng to receive APRS consistently you need to turn off power savings and turn off squelch. If you turn off squelch VOX does not work, so no transmission. You need to turn off squelch because most Baofengs are not quick enough with the squelch on to get the first part of the packet and APRS is all or nothing when it comes to a packet. So because of the radio you can receive or transmit not both using this cable. ## Features - One Cable, Infinite Possibilities: The BTECH APRS-K1 Cable is your passport to the expansive world of over-the-air communication.

Perhaps your iPhone needs this adapter? It should have come in your package.As for the radio getting hot, is it transmitting continuously without a break? **Q: I bought this the aprs-k2 cable and am connecting an iphone 5s and a uv-5r. why does it always activate vox and intermittently transmit?** A: I use an iPhone 5 (not 5s, though) and a UV-5R, and I've found that I need to find just the right volume settings on both the phone and the rig. On the phone I have the volume set at about 2/3 and on the rig it's set at about 1/3. I also set the vox to 4. This cable actually solved the vox tripping problem I had when trying to do APRS with my iPad instead of my iPhone, so I know the circuit can do the job with the right settings.
