This is experimental release featuring potential messenger support for repeaters. This is based on the interest expressed by couple of Patreons.

More context is available here: https://github.com/kamilsss655/uv-k5-firmware-custom/issues/213

There should be 2 seconds delay between PTT and message being sent hopefully giving time for the message to be relayed by the repeater.

PS: Please let me know if it works with your repeater as I have no way of testing this.

Enjoy!

Spent more time on this using two different repeaters, one 45w 3 miles away on a big tower (wideband) and one 5w (narrowband) temporary repeater at my house....sadly I cannot get a decode to happen regardless of which repeater I use. I tried watching the signals on the SDR to see if I could pick out any kind of issue but I don't see it. So then I spent some time testing tones on simplex to see if I could find an issue and I found that when there is tones on both TX and RX (TSQL) , the messenger does consistently fail to decode . I tested this only with my repeater tones, 141.3 and 103.5. So I tried setting the home repeater to just carrier sql on transmit but messenger still does not decode...however I am thinking the tone for transmitting on the repeater (repeater receive tone) is possibly being carried through the repeater and out the transmit side and causing the issue. I can hear the AFSK burst come through the repeater but I am thinking the tone is bleeding through and distorting the AFSK so much that it cannot decode. You would certainly know more about that aspect and how the tones could affect the AFSK .

Merry Christmas by the way :)

Yup I suppose in most of the cases there is distortion added by the repeater. I guess this experimental feature is not going to make it to main release. It was a good experiment though.
