Has anyone added a crystal heater to their K2? If I would add a heater
to my K2, what oscillator would be the best one to do it to or should I
heat both the 4mc the 12.xx mc crystals? The radio is decent as is but

I'm a general dummy, but I dont think that simply adding a heater will
do what you want, but then again when i think of stability my brain
usually thinks of 0.5ppb over a 20year life of a radio.

Mike,
I don't know what kind of stability you are trying to achieve, but the
PLL crystal would be the only one to consider. The 4 MHz crystal is not
used dynamically for any frequency determination - it must be set
accurately and used for the short term running of CAL PLL and CAL FIL,
but
Hello All,
Anyone know if the RX antenna input is shorted to ground when the K3 is
put into TX mode ? I have been getting some funny stuff going on when I

Jerry,
If the funny stuff is hearing a clicking sound, that is the sound of
the COR relay kicking in to protect the receiver.
The only cure is better isolation for your receive antenna from the
transmit antenna.

Older firmware showed the IF bandwidth when you rotated the WIDTH
control. Beginning with
Jerry,
The WIDTH control sets the final audio bandwidth, which is limited to 5
kHz in AM mode. But in AM mode, the crystal filter bandwidth needed is
2x the audio bandwidth, or 10 kHz in this case, because it has to pass
both sidebands. To obtain this full bandwidth, you'd have to have the

The simplest way I know is to have a remote PC connected to the K3 running

put ethernet in the rigs and we will have native

Hi Bud:
If you make sure that the MMTTY Mark freq is set to the same pitch as

It seems odd to have to purchase an expensive filter to obtain a wider

I still would appreciate more bandwidth for CW. 2.7khz is far too narrow for
comfortable monitoring while working around the shack.

Hi Steve,
We convert directly from our 1st I.F. of 8215 down to a 15 kHz 2nd I.F.
(DSP). Without a narrow filter at the first I.F., you'd have an image
response at 8215 + 15*2 = 8245 kHz that would pass through unimpeded.

Hello Jerry,
I'm already doing this with my K3. It's easy to setup if you use e.g. HamRadio

You might try clicking the fine/course button to the right of VFO A. See

The smaller VFO B knob is because there is no subrx in this rig. There is more
finger room around it.
The large knob is set to low friction, requires only a light touch
