As to CW & the K3...

I use iambic paddles. I Always used keyers based on the Curtis 8044
like the Ham Keyer HK5A. I still do. I remember the TenTec internal
keyer was a different kind of logic and I had a terrible time with
it. If I remember correctly, it had an issue with extra dits getting
inserted at the end of certain characters. I went back to the "Ham
Keyer".

Anyone know if the keying logic that's internal to the K3 is the same
logic as the Ham Keyer HK5A? It would be wonderful to be able to plug
the iambic paddles into the K3, shelve the HK5A and have one less
item on my desk.

Hi Gary,

The keyer state machine in the K3 firmware emulates the Curtis keyer chip if you set IAMBIC = A in the CONFIG menu (default). It emulates the "Super CMOS" keyer's mode B if you set IAMBIC = B. Based on your description, I think you'd like mode A.

Some K3 owners have asked for emulations closer to other keyers. Firmware can be changed ("small matter of programming"). Enough said ;)
