Bands pretty lousy today, but heard a weak YR10RRO on 17M. Noise level
about an S5 to 7. I was using DM780 and the WinKeyer option for sending
as my fist is not good due to arthritis. When I looked up at the decode
screen on DM780 it was doing a very good job. So I began to play with
the settings for bandwidth and squelch and it was doing a really good job.
After reading some of the comments lately on the K3 CW decoder, I
decided I would do some playing with it as well. YR10RRO was gone but
ZF35LC was there and I am pleased to say, the K3 was doing a good job as
well. So again I began to play with the available settings and by
adjusting the threshold and bandwith, I found it to do a really good job.
All of the above was done with slow AGC. I suspect further improvement
would be possible by running with AGC off and reducing the RF gain to
improve the S/N ratio. Like virtually all of the decoders I have tried
from CWGET on to the present, it takes a character or two for the
software to "lock on". After that, the results were very good.
I probably would give the edge to HRD with DM780, but the K3 was hanging
in there, perfectly acceptable as far as I am concerned were I an CW OP
looking for a bit of help.
The lineup here is a K-Line with a Navigator interface and I will have
to give credit to the Navigator as well for its very low noise CODEC.
Just thought some might be interested so thought I would pass it on.
73s Jim, W4ATK
