Re: radio to radio operation


 

Hello Mike and Group:


Thanks for the follow-up:


1. Do the radios transmit when D-RATS sends data?

*** Yes - tx and observed reception by the target radio.

2. Does the receiving radio display the call sign and message from the transmitting radio?

*** Yes, I do see the transmitting radio's call at the receive radio, but in the DRATS chat and log screen, I just see CQCQCQ. I have turned TX Messaging off on these radios as I saw a note saying TX messaging may interfere with DRATS chat message bandwidth - so no TX Messaging on receive radio as expected.

3. Is either radio in "power saver" mode? Power saver mode sometimes causes the radio to miss parts of the D-STAR header message as it "wakes up".

*** Nope, power save and auto off features disabled.

4. Is the rf path between the radios good? D-STAR does not provide error correction for the low speed data channel, so if the path is bad you will not get data transfer.

*** I believe rf path is good. DSTAR audio between radios is fine (only 5 feet between radios, but both on low power mode).

You might consider posting your debug.log file so we can see any messages

*** On the logs, rookie response: I don't see any log files in the DRATS directory. I do see the Event Log. How/where might log files be (or be generated)?

Thanks,

Hi Jeff,?

Some questions that may help us understand what is happening:
1. Do the radios transmit when D-RATS sends data?
2. Does the receiving radio display the call sign and message from the transmitting radio?
3. Is either radio in "power saver" mode? Power saver mode sometimes causes the radio to miss parts of the D-STAR header message as it "wakes up".

Hello All:


I am trying to run DRATS radio -to- radio, with Internet and Ratflectord disabled. Radio setup for com port and baud, and port <=> radio tested via programming as OK.

Raw and Sniffer says transmission is received, but no text in Chat or seen in log.

TX Message off, no GPS TX on both radios.

Any thoughts from the group?

Thanks,
