Hi
I have the following issue with my remote TS-480:
when TXing in CW the first 1 or 2 characters are corrupted but then it works fine for the rest of the passage. Next passage, again: first 1 or 2 characters corrupted, then fine.
I am able to test the behaviour only in 80m, where I can RX my own signal on the control site but other OMs on the radio site have confirmed the issue on other bands too.
I would almost certainly exclude an RFI issue and I would rather say it has to do with some buffer but I have already set buffer size, jitter and delays to the max value almost
I have the following settings:
Control Site (cable connection):
Rx jitter buffer size 16
Rx jitter delay 15
Audio packet size (ms) 40
RTP tx mode 1
....
UDP cmd min-data-size 10
....
Lf delay ms [0-500] 400
Key delay ms [0-250] 200
Radio Site (WiFi connection to fiber router):
Rx jitter buffer size 16
Rx jitter delay 15
Audio packet size (ms) 40
RTP tx mode 1
Disable audio tones 0
The typical ping time is 50ms
Even if annoying, I can still live with this issue in normal QSOs but it is almost impossible to work DX stations or contests.
I haven't been able to find any similar 3D in the forum. Any suggestion?

does anyone have a clue?
I have tried to increase "UDP cmd min-data-size" to 99 but no improvement

Hi
packet sizes and jitter bufers are not involved at all in CW-keying
you can try to set PTT activated by keyer =yes in the Radio-RRC
also set Key-delay to minium 50 ms in control-RRC maybe higher
if you have a mobile internet connection they sometimes are slow to setup the data stream then it can work by setting RTP tx mode = continuously in control-RRC but be aware that data is sent all the time in both direction so the data cost will be x2 if it's not free
