K3 Ham Radio Deluxe - Tuner Macro

[rkayakr]

Great news about HRD support for the K3

My first macro is a "tuner" command to replace the unfortunate "tune" behavior of the K3. Unlike the K2, which drops power to about 20 watts, the K3 will use whatever power you are set to. This isn't good for the tuner or the K3.  I have already caused my K3 to instantly thermal trip by forgetting to turn power down to tune and then back up.

here is a short CAT command that I attached to a button I labeled "tuner"
PC020;
SWH16;
@ 1000;
SWH16;

You still need to remember to turn the power back up, but it will be gentle to your gear.

If anyone knows a more elegant solution I would like to hear it.

FB, Bob.  That's plenty good enough to keep from arcing the relay
contacts on my SGC antenna coupler, not to mention reducing the QRM a
bit.  One thing I could say for the Icoms I have had is that they had
the ten watt tune function that they used with their external tuners.
That always worked fine for me.  Thanks.

For clarification, the K3's internal tuner *does* reduce the power when
activated by the ATU button, (I think to 5 w). Bob is apparently talking
about using an external tuner with the TUNE button, which does put out
whatever power the radio is set to.

I hope that this can/will be fixed in a future firmware version for
those of us using external tuners. I don't think it would be a good idea
to send 100w to my LDG while it is tuning. In my opinion the K3 should
follow the same behavior that the K2 does in that it should output at a
selectable lower power when the tune button is selected even without the
internal tuner.

Right Vic

As stated in my original message I am referring to the action you get
when you hit "tune" not "ATU tune". I do not have the internal tuner. I
have an amp I occasionally use, so my autotuner is external.

When I hit "ATU tune" the K3 politely informs me that I do not have an
ATU installed and does nothing.

Again, the K3 behavior is different than the K2 and every other
transceiver I have seen. I hope that this will one day be changed, but I
think Elecraft has bigger fish to fry today. So - meanwhile Simon's
excellent software provides an easy way to shape actions to suit my needs.

I like external tuners because I can use one tuner on a several
different radios. I can use one external tuner with my K2, SDR-1000 and
soon my K3, instead of having to purchase a separate internal tuner for
each radio. I am sure that the K3 internal tuner is a better tuner, but
it is a setup that works well for me, the LDG tunes the antennas that I
have with no problem, and it saves me money that I can spend on other
things.
