I logged in shortly after I had a QSO on the repeater and the load average was 0.00, 0.01, 0.00. I also noticed while having another conversation on the repeater this morning, the problem started after 5-10 minutes or so, up to almost 7 syllables. Then the other user went clear for 5 mins, then came back and we continued the conversation with no delay for a further 10 minutes.
I've disabled the voter record function in the channel driver for now, just in case that is the issue.
I guess I could try another RTCM/Voter unit sitting at the Master site with no radio attached at all purely for timing.
Sam - what did you change your buflen too?
My current config -
buflen = 140 in voter.conf
Tx Buffer Length in RTCM's = 1120
