Hay all.

Do You have same issue ??
There is delay between what i hear in headphones and what i'm keying.
When I work locally all is ok (kay and phones connected to main unit).
But i bought this radio with intention of remote work and because of delay this is useless especially when there is keying over 20WPM.

Have You any solution for that ?

Hi,
It's mentioned in the User Manual:
Signal output delay via the sound card can reach 250-500 ms. It can be adjusted with buffer size (smaller values equal lower delay) or selecting different Audio driver (MME – the biggest latency / WDMKS – moderate latency / ASIO – minimal latency).

Thanks for info.

Anyway any kind of delay makes keying through RS232 useless because sound doesn't follow hand :-) and situation goes worse and worse with speed.
Sidetone should be generated locally from ExperstSDR2 instead of radio when key is connected to RS232.

I will try to connect external keyer and se that all be ok.
