Hi all,
I'm sorry for the many emails today. But i have another idea for
Domenico:
You could run a 3rd 'channel', e.g. 137.485 kHz (still oriented on the
current frequency section) and indicate/define this channel (3) as a
'local' channel, whereas the other channels are indicated as 'medium'
(2) and 'DX' (1).
The difference in the settings in these channels (apart from the
frequency of course) is the list size!
Local stations or strong stations like me will decode almost every time
at rank 0, so you can use a very small list length for that channel,
e.g. 50.
A weak/distant station or in times of high QRN one (e.g. VO1NA) would
prefer to use one of the other channels, just in case that the rank
will be much worse.
You can see that most of the 'false' decodes happen at list lengths of
> 5000. So with the use of different list lengths you can avoid
several false decodes, CPU usage and false entries in the log file.
For the 'medium' channel you could use a list length of 1000 and for DX
maybe 20000.
Just an idea :-)
Using two frequencies has already improved the situation:

In a few minutes i will try to run less antenna current to come closer
to the limit :-)
Thanks for the great service :-)
