K3 Twin 1258 Strapping PCB

[G4ABX]

Good morning.

Still trying to debug my 'No PTT on SSB' issue:

Can someone tell me if the RRC supplied 'Strapping' PCB's for the Elecraft K3 twin setup are identical?
In other words, are there unique 'Control' and 'Radio' strapping PCB's?

If they are not identical, what are the differences?

they are identical

What does the the status page in the radio RRC says about PTT status  if you press PTT and update the page ? Are you using our cables ? Check that the cable work by shortcut pin 3 and 5 in the RJ45 plug. We do not test the mic cables when receiveing them from the producer but I have never heard about any problem with them.

Good afternoon Mike

Thanks for confirming the Strapping PCB's as identical.

When I push the PTT button and refresh the status at the control end, PTT status indicates 'ON'

The headphones (plugged into the RRC) mute, and the Mic is enabled but the K3s doesn't switch to TX. The only way I can do that is with the front panel XMIT button.

If I use the K3s in 'Normal' mode, Mic/Footswitch work fine.

I'm wondering if this is a K3 issue and nothing to do with your kit -- which I must say is now working superbly well in terms of quality both ways if I use the XMIT button on the K3s -- even on a terrible Internet connection!
