Today I received my BTech APRS-K2 cable to connect my computer/mobile device to the AnyTone D-878UV so I can use the APRS mode on 2m.

First I labelled two channels (see EI7IG’s APRS Page):

1. “APRS” on 144.800MHz
2. “APRS Voice Alert” on the same frequency, but with a Squelch setting that is opened by a tone of 136.5Hz and it transmits that tone as well.

The first one I don’t make part of a scan list, the other I have. Here you see the detailed settings for it:

And here the settings for the second one:

Great! Now that the radio was happy, I decided to enable the Vox setting and connect the radio to my iPhone where I run aprs.fi for iOS. Receiving worked great but transmitting seemed to fail? Following the instructions to the letter, I had enabled the VOX feature. After a lot of fiddling, I was going back to the AnyTone CPS’ Optional Settings and I noticed (by accident) that the VOX was only enabled for the internal microphone. You need to enable it for the external microphone only. That way you can still use it for handheld use:

Now, using my Baofeng UV-9R I could hear the transmission. Not sure if it went anywhere, at this time there is not a lot of activity happening. To be continued…
