Bob,
This is the same problem I have had ever since I tried to take band data
from the Icom CI-V Buss. It just does not work! I think there are just too
many collisions on the half duplex buss.
Writelog itself has difficulty getting a frequency reading in a timely
fashion. Notice that your Band Map sometimes re-draws with Zero frequency.
When you put the W5XD keyer also on that rig control channel as I did,
things get really bad. I have moved the keyer back to the other radio to
get it off that circuit. Then I have taken the band data from the voltage
signal on the din plug on the back of the IC-756 to a band decoder and use
that to drive my antenna switching, band filters and linear (but this has
the ambiguity on 17 and 12m which really screws things up) Then Writelog
can take it's time trying to get a clear message from the CI-V buss and if
it fails (takes too long) at least the only damage is the Band Map flickers.
It is my understanding that Transceive On generates a lot more traffic on
the buss, ie more collisions. And that the SteppIR reads the buss directly
- this stopped me from buying one for the new station. Why Icom sticks with
these old architectural mistakes is beyond me.
There is no solution, that I know of, other than getting off Icom
equipment. The CI-V buss just doesn't work very well even with one radio. I
can't imagine the babel with 4 radios. Nobody would ever get a clean packet.
