Has anyone married the three of these so that the KDVR3 is used for voice

For your button problems, I would look on the front panel. Check RP1 to
be certain it is installed the right-way-'round (this particular RPak
cannot be swapped end for end like many others can). Also check the
soldering at the switches as well as U2 and U3.

To use the base K2 BNC antenna jack, you must remove the KPA100 - if you
attempt to use that jack, the load impedance between the base K2 and the

Jim,
You say that foam dielectric is more costly and provides no benefit at h-f. If
you are only considering dielectric loss this is true, but the lower effective
dielectric constant allows (requires) a larger center conductor (for the same
overall diameter) which fulfills your big copper

I have a fairly new K3 for sale. I purchased it new from Elecraft in
June of 2009. It is Serial # 3159. I have been very happy with

popularity among DXers and Contesters world wide.
The trouble is, I am not a serious

While on the subject of the KDVR3, I wonder if the next beta firmware
release will include a feature that automatically turns MON on at a
predetermined level when a recording is being transmitted, and off again
when transmission is finished? It has reputedly been on the list for a
year or so.
I was running my K2/100 at 40W during PSK and the heat sink was too hot to
touch (ooops!). Now it has the following symptoms of sickness:
- in CW mode key down it generates either 100W or 10W when in high or low
power mode respectively. In other words, always outputs maximum power.
- in SSB mode
Hi Guys,
The K3 is sold.

Since it always transmits at maximum power, that alone may be your only
problem. Look at it this way - if you had 40 watts requested and it was
putting out maximum power no matter what the power setting, it would be
operating at 100 watts or more and yes, on PSK, the heat sink would

If so, try adding a .01 uF capacitor between the base and emitter of
