D-Rats Packet Mode Questions


 

Hi All:
Just found this resource dated 2018.? Apparently the test was successful.??



Anyone able to replicate this?? AGWPE requires a Windows machine for server side or could be supported from regular d-rats repeater (raspberry pi)? I saw it uses soundmodem which I have tested before for WinLink packet.?

Think this could be really, really positive.?

Hi again:
Particular interest is IF D-Rats packet mode (AGWPE - soundmodem) could connect with a BPQ Packet Network. The Philadelphia Digital Radio Association have a D-Rats packet functionality but not sure if BPQ.?

? ?Yes, we have done this many times many tests. Several things to remember

1) Tell all users DO NOT USE THE PING FEATURE...This Will cause massive collisions on the freq.
2) Set your TX DELAY as fast as your radio can handle...( Not all are the same)
3) Let Hang Time be default ( Ussally )

Other setting tweak until it works for you. Sometimes a user can/will miss a?
A message depending on traffic and how good a signal you have from the D-Rats server.

Hope this?helps.

Lee:
Have a doubt when you refer to:
"A message depending on traffic and how good a signal you have from the D-Rats server."

My conceptualization was something like:

D-rats client --> Packer soundmodem --> IC9700 (RF) --> RF Network (BPQ)

Not sure where the d-rats server fits or is required. Sorry for my ignorance.? I run a d-rats repeater (raspberry pi4) inside an AREDN? Mesh (internet based PVN) but still waiting for users within the mesh to install D-Rats and test. Mesh users are few at moment.

That's what I meant Repeater.

Sorry

Hi Again:

I am getting connected but getting scrambled characters at D-Rats screen. Any suggestion about sound modem settings?

Thanks again!

Hi:

This is what I am getting:
[15:32:01] [callsign-Packet] CQCQCQ: h@@th@
?
[15:32:09] [callsign-Packet] CQCQCQ: h@@th@
?
[15:32:18] [callsign-Packet] CQCQCQ: h@@th@

I can see packet exhanges at soundmodem but at D-Rats, scramble.?

Btw.. there are several offerings for a AGW compatible packet program:

?? - Direwolf which runs on Linux, Windows, and Mac
?? - UZ7HO Soundmodem runs on Windows and with Wine, it runs on Linux
?? - Qtsoundmodem - a Linux port of the UZ7HO software TNC
