Wait, scratch that... it will pass because the total number of letters/number in the Callsign is under 6... 

however, something like WB5ABCD will NOT...

Yeah, a 4 long suffix fails AX.25 protocol for a callsign.
It should be fine as an object/item name tho.

Hi James,

 

I had not thought of that but I am almost positive it worked sometime in the past. I tinker with direwolf.conf and the Python script every now and then, so, it is very possible something was broken. However, in theory, the only thing I changed recently was the offset. I found I was generating a negative value occasionally.

 

Best regards,

Fred,

 

You have a 4 letter suffix on those two stations. 

 

The program might be barking at that. 

 

Have you tried it with a three letter suffix?

Greetings Lynn,

 

I have a bit of a telemetry mystery. The station is N7FMH-2 and telemetry packets are for N7FMHL-1 and N7FMHL-2. There is no record of telemetry in my APRSIS32.xml. However, It does show up on APRS.FI (copies below). That is the mystery.

 

N7FMH-2 is a battery box with a Raspberry Pi Zero running Direwolf Version 1.7A. It is only over RF.

 

Direwolf 1.7A has a feature which allows N7FMH-2  to send multiple telemetry packet by changing the “source”. It is sending from two sources, N7FMHL-1 and N7FMHL-2. There are 10 fields in use.

 

Thank you!

 

Best regards,

Fred N7FMH
