Re: Using secondary port of Commander for CW SKIMMER ?

Andrew OBrien

Bingo ! Got it now , thanks Dave . Knowing that I should stick to the K3 settings was the part that helped .

For anyone following this thread . The 705 can be used for Skimmer functions by setting the 705’s “USB AF/IF Output” to IF. I’m seeing skims for about a 24 khz range . Having a little CW Skimmer action works very well with Spotcollector and DXKeeeper.

I had to resort to reading the instructions about using CW Skimmer with Commander's secondary port.

I see I'm even quoted in that section ! Now , however , I am trying to configure the an Icom.

Back in the day I think I was using Kenwood products . The instructions reference an Elecraft

I have Commander connected to port 3 that is installed by Icom drivers . That is working fine . I have virtual ports 5 and 6 created and paired . I have the Commander secondary port configured for port 5 with 'enabled' checked . I have Omnirig configured for port 6, however CWSkimmer and Commander's secondary port do not see each other (I do have 'follow and lead' checked ) . In Commander's secondary port config area should I choose Icom as the radio (with A4 as C-IV address ) or is this a case where I should be using a generic Kenwood as the radio setting ? I tried making sure the baud rate in Commander equalled that of Omnirig and tried various combinations for DTR and RTS . So far , no success . I did succeed in getting the frequency display in CW Skimmer to light up, but frequency equalled 0.0
