[Elecraft] K3 and Microham keyer II

[Joe Subich, W4TV]

Please read and study the microKEYER II Users Manual!

All PTT inputs (PTT port, 2nd PTT Port, WinKey PTT, Foot switch, mic
PTT, etc.) are in parallel (just like the K3).  The PTT Outputs are
selected on the PTT Tab in microHAM Router - with PTT1 being the PTT
connector on the mic cable and PTT2 being the PTT connected to the
back of the rig (ACC jack for the K3).

If you have a PTT1 LED on MK II, you must connect the mic plug
to the rig in order for it to actually key the rig.

If you want to use PTT2, you need to select PTT2 for FSK/DIGITAL
on the PTT tab in microHAM Router, the K3 must be in FSK, AFSK A
or DATA A mode, and microHAM Router must be able to "read" CAT
data (frequency and mode) from the rig.

BTW, I see that Airlink Express has made substantial changes since
the set-up example was written.  It looks like FSK works properly
now (even though there are still significant user interface issues)
- but I will need to update the example(s) to cover FSK at some point.

73,
