[Elecraft] K3 3.30 FW 80M split-strange behavior

[Mark C. Killmon]

Hello,

 

Can anyone reproduce this one, or is it just me?

 

80M, A VFO on 3.515, no sub receiver (I don't have one), B VFO on 3.518.5.
Key the transmitter (PTT via a footswitch or front panel XMIT) and the
receiver comes back with vy. low sensitivity. Key it again, receiver is
fine. This effect is totally repeatable, toggling back and forth. No split,
no problem, so it's not the RF path and/or antenna.  If I use the XIT to
accomplish the split, I have the same problem.

 

Here's the real kicker. When the split is less than 3 kHz or greater than 5
kHz, the K3 doesn't  behave this way.

 

If I use VOX, no problem. The same configuration on 40M doesn't produce this
problem.

 

This might be a "If it hurts when you move your arm like this, don't move
your arm like this" situation, but I generally use PTT via a footswitch and
this split is not unusual. I'll run VOX to get around it for now.

 

V. 3.30 FW, 2.26 DSP
