Re: Turn Off Transmit Message on Radio
|
For N3TSZ, many thanks Pat.? I had to search how to change the COM port from 11 to 3 but was able to do so.? And I found a setting for the ID-31A under Function that is called Data Speed.? The manual says for low-speed data transmission it should be 4800 but for connected external devices (e.g. GPS), it should be 9600.? The default is 9600!? So after setting 4800 and COM 3, we were successfully able to transmit low-speed data emails 100% through two different repeaters (W5SF and W5MPZ).?
? Do you know if we can also use a linked reflector? ? And thanks again, you helped us make another step forward in using D-RATS together with D-STAR as a valuable EMCOMM tool.

Try setting warmup timeout to zero and warmup blocks to 16. This prefixes empty data blocks to the D-RATS data, thus giving the repeater/gateway time to open a path before the real data starts.
Also consider that the low speed data portion of the D-STAR stream does not have forward error correction as the voice segment does. If you are hearing R2D2, (it sounds like Cousin Itt to me) you may not have a good enough signal into the repeater for a reliable connection.
If your radio transmits when you press send, you have it set right.
If you are using a USB data cable, try going to the device manager and changing the port number to 4 or lower if possible. I have also heard that manually entering the com port number rather than selecting it from the list will cure the issue.
Hope this helps,
Patrick
