K3 Amp Key configuration request

[Phil Salas]

I use my K3 with an Ameritron ALS-600 amplifier and MFJ-998 autotuner (hey,
the KPA-500 and KAT-500 aren't available yet).  Anyway, I tune the MFJ-998
by leaving it in the full auto position and then just press TUNE on the K3.
I set my K3 TUNE power for 15 watts which is a perfect level for the
MFJ-998.  However, the amp enable line on the K3 goes low even when using
TUNE, and so I must remember to place the amp in standby before checking and
tuning SWR.  Otherwise the amp will put out power momentarily (60-100 watts)
until the MFJ-998 interrupts the amp-key line if it needs to tune.  It would
be nice if the amp-enable output of the K3 would not go low when using TUNE
on the K3.  Maybe a menu set-up option?

On the other hand, I have the TUNE power level set at 7 watts, and use it to tune my Alpha 89. So the amp-enable line is needed in my case! I imagine user defined menu selection would allow for either situation......

Same situation here. I'd like to see this too.

In addition to this, I have following issue: if I touch my paddles while
receiving, my ALS-600 is keyed. The K3 stays on receive (as I set it up),
nothing is transmitted, but the relay in the amplifier goes crazy trying to
keep up with Morse. Is there way to set K3 to key amplifier only when I
actually transmit?

 

Thanks,

 

Igor, N1YX

Please add my name to this request.  I have the same setup as Phil and
Roger.  It would sure be handy if the amp enable line setting could be
custom configured to adapt to this specific environment.

Why not set the tune to 1-2W? K3 allows for this as opposed to nearly all other radios.
The number of software options in K3 is reaching the sky and many problems of current operators stem from not remembering options that were turned on by mistake.

I think you would find that, with a remote coupler and a low drive linear,
2 watts would not be enough for the coupler to tune properly and if the
linear was in line, the output might be too much for the couplers relays
to handle safely.
