Yes, practical lesson learned
However, there is something else going on. If I wait for the screen to turn off (15s) and then another about a minute then the receiver stops receiving messages. If I wake it up with a short PTT push from the sender (just to open the squelch) then it starts receiving again. The power saving ratio is 1:1 - I may experiment with that and also look for some sleeping settings in the software.
I am glad that I got at least a few of them through - now the troubleshooting starts ....
I came across this post while searching for some info. I don't know if you resolved it but will post the solution in case anyone else has the issue. Turn off the power save option.
From the Alinco DJ-MD5 users manual -
20. Power Save
Turn on to active the power save function, to prolong the battery life.
Save 1:1, work 30ms, dormant 30ms.
Save 2:1, work 60ms, dormant 30ms
When turn on the power save, it may not receive the message in time
