APRS Tx mode is now set in Options->APRS options

Details of APRS modes from Daniel F1RMB
• Mode "Manual"
o it send a beacon each time you press SK1 + 2
• Mode "PTT"
o it send a beacon each time you release the PTT, but if "Interval" (Initial interval) has timed-out:
if "Interval" is set to 1 min, if you release the PTT and the latest beacon was sent happened less than a minute ago, it won't beacon.
Decay On/Off as no impact
• Mode "Auto"
o Send a beacon at "Interval" minute
if Decay is ON, each "Interval" beaconing, the "Interval" is doubled, until *32 (Decay is mostly designed for fixed position)

e.g. "Interval" is set to 1 min, beaconing interval will be: 1min, 2min, 4min, 8min, 16min, 32min, 32min, 32min.

If position of the radio moves then the Decay is reset.
• Mode "Smart"
o "Interval" and "Decay" are not used.
Only the settings "Slow Rate, Fast Rate, Low Speed, Hi Speed, T. Angle, T. Slope, T. Time" are used (as it's designed to use speed/course in the beaconing process).

There are ‘presets’ for the Smart setting values., buy pressing number buttons 0, 1, 2 , 3 ,4 , 5 or 6.

0 = default, 1 = Car, 2 = e-Bike 3= Bike (bicycle), 4 = Walking, 5 = Sailing (boat), 6 = Settings used by APRSDroid App

Also. Options -> General options ->GPS now has an additional value of "Log" (after NMEA in the list of values)

Selecting Log, causes the GPS position data to be logged into the Flash memory of the radio.

Each time the Log is turned on it creates a new entry, and when log is turned off it closes that entry
The CPS has a new feature to read the NMEA data from the radio and save the data has been recorded in the radio.

To visualise the GPS data use

Also, SK1 + 1 enables or disables aprs beaconing, temporary.

Note that satellite APRS isn't impacted by all.of this, it means that each time you press the PTT, a beacon is sent, regardless of any timer (only APRS Options -> Location has impact).


Cheers.

Installed, beaconing appears to work as described (both smart and auto), intervals work perfectly and messages decode correctly. I've set it on VFO mode at the moment and it transmits on the TX channel set. Usefully you can still TX manually when auto mode is on, and this seems to reset the decay timer, so if you know you're going to start moving and you want to send a packet before you set off then you can. Am only picking up the response locally at the moment (on Pi with NinoTNC connected to a Yaesu 8900 to listen), not feeding to aprs.fi, but will test it going around Harrow and Watford tomorrow where it should be picked up.

One thought for the future -- it may be useful to send the APRS "in the background", that is you can keep the radio listening to whatever channel you want to monitor and when it's time to auto-TX the APRS packet the radio could auto-switch to a dedicated APRS channel (where the frequency is set), send the packet, and then switch back. Probably already in plans, but I thought I'd suggest it. (This is how auto-aprs tx works on my Retevis RT73).

Great work guys :-)

One cool thing I've noticed is that it "saves up" the APRS timer, so if I'm on a memory channel (monitoring or having a QSO or whatever) and then I switch to VFO mode, the APRS packet is sent immediately upon change.
