I did a little testing on this tonight to see if I could document any clues.? Here’s my configuration, test, and conclusion.

?

Configuration:

Station #1:?? D-RATS – 2820 Radio – Local Icom Dstar Repeater – REF030D

Station #2:?? D-RATS – ircDDBGateway on a Raspberry Pi – REF030D

In this configuration I’m not running any of Jonathan’s repeater apps – only ircDDBGateway.

?

The ircDDBGateway/Pi configuration is how I run my DVAP and a NWDigital board, So, I’m confident it works.

?

Test:

If I transmit from D-RATS on Station 1 I’m not heard on Station 2.? But, I was able to chat with Patrick (N3TSZ) from Station 1. ?Patrick was seeing me because of another ratflector that is linked to REF030D.? If I transmit from D-RATS on Station 2 I see the message on Station 1, and Patrick confirmed that he saw the message.?

?

While doing this test I ran Wireshark to capture packets between Station 2 and the Pi.? I see two way communication when I transmit from Station 2.? I was able to dig through the packets enough to see the text of the message I transmitted, and I see a single ACK packet back from the Pi to the DRATS station.?? But, nothing else.

?

I also did the capture from my router so I could see what was happening between the Pi and REF030D.?? I see two way traffic there for every packet that is sent from either Station 1 (I believe this is correct, may need to confirm it again) ?or Station 2 (I’m positive on this one).

?

Conclusion:??

I am able to send successfully from D-RATS connected to ircDDBGateway to REF030D, but I never receive any response other than an ACK packet from the Pi.?? I appear to have traffic between ircDDBGateway and REF030D for all traffic on ?REF030D.? ircDDBGateway does not appear to be sending anything back to D-RATS from REF030D even though ircDDBGateway is receiving packets.? ?

?

If Jonathon is interested in exploring this further I will be happy to provide my packet capture and do any further testing that I can.?? If anyone has an idea of something else to test here I will be glad to give it a try.
