<div dir="ltr"><div class="gmail_extra">Steve,</div><div class="gmail_extra"> </div><div class="gmail_extra">I can confirm from use that APRSDroid will decode packets appropriately through the audio input on Android devices as I've done it with a HTC Evo and Samsung Galaxy S3. I've used both extensively over the last two years for RF work. </div><div class="gmail_extra"> </div><div class="gmail_extra">Given the fact that you're having the same problem on more than one device, the problem may be with your cable or your radio. I know you said your audio levels are good based on the in app sound level meter, but have you listened to what the phone is receiving to make sure the quality of the sound is good (it may be loud enough but completely distorted or broken beyond the software's ability to decode)? If you're using a HT indoors or inside a car, that scenario is very likely.</div><div class="gmail_extra"> </div><div class="gmail_extra">Two options to test this. One, get an audio connector with two female ends and plug some headphones to the audio cable that you're using for this setup and just listen to the frequency for a while. Two, use an audio recording app on your phone/tablet to capture some samples of what your radio and cable are passing along. If the quality of the audio is bad, you know you're on the right track and you can perform further testing to isolate the problem to your radio or your audio cable. </div><div class="gmail_extra"> </div><div class="gmail_extra">Let me know how that goes and I'll help you troubleshoot further.</div><div class="gmail_extra"> </div><div class="gmail_extra">As a side note, if anyone is interested in doing something like what Steve has done, I've put together some instructions for using APRSDroid as a virtual TNC and APRS display/interface as well as a video for tying APRSDroid to an external Bluetooth TNC like the one from Mobilinkd. Steve, if you ultimately hit a wall on this audio cable project, you might want to give the Mobilinkd a look.</div><div class="gmail_extra"> </div><div class="gmail_extra">Hardwired Cell article - <a href="http://www.wcares.org/?page_id=2677">http://www.wcares.org/?page_id=2677</a> </div><div class="gmail_extra">APRSDroid and Mobilinkd TNC video - <a href="https://youtu.be/eMMe63si2aY">https://youtu.be/eMMe63si2aY</a></div><div class="gmail_extra"> </div><div class="gmail_extra">Dallas</div><div class="gmail_extra">K7DCC<br></div><div class="gmail_quote">On Tue, Aug 4, 2015 at 12:00 PM, <span dir="ltr"><<a href="mailto:aprssig-request@tapr.org" target="_blank">aprssig-request@tapr.org</a>></span> wrote:<br><br>

<br>
There are several different implementations available for building a<br>
receive-only APRS Internet Gateway (IGate) with only a Raspberry Pi and a<br>
software<br>
defined radio (SDR) dongle. Here's one of them ...<br>
