Guenter, The suggested operation would be that you hear both your transmitted signal and the band between dots properly aligned, only delayed by the latency interval. In practice the 5K doesn't do this. You might hear the band during the start of the first keying element. Then only pops and crackles.
Assuming this could be fixed, then there is still the problem of hearing your own keying delayed. There is a threshold where the delay impairs keying. For me that threshold is below current latencies. PwrSDR does not appear to delay the monitor sidetone by the receive latency period, which makes keying easier but blocks hearing the band. 73 Ed W2RF On 25 Apr 2008 at 10:13, guenter wrote: > Am Freitag, 25.
