I'm very happy with my West Mountain Radio COMspkrs.
Have had no problems with RFI at high power levels (1KW).
Regardless of what speaker/s you use, remember not to
insert a mono plug into the rear speaker jack. (;-)

The one thing I miss is the APF in my FT-990 and FT-1000D. (:-)

Help:
I bought the West Mountain COMspkr for my wife's computer to
eliminate RFI when I ran HF. They are advertised as RFI-proof and
worked for us. I have not tried it as a radio speaker.
If you can find an old ham receiver speaker from the 1950's they have
a wonderful sound that is hard to match
This is a really good thread and I'm enjoying reading the theory!
I'm always being called off frequency during contests so SHIFT would be the
obvious choice!
Being an ex FT2000 owner I used the contour settings and it was bril.

I am not sure about the hang of this forum thing. It is just public
email where we try to help each other with Elecraft products.
You may have a problem with that wattmeter rather than the K2. Analog
metered wattmeters are notoriously inaccurate, especially at low power
readings.
Hy to all. Just performed the test as indicated on page 22 of the manual i have
2 values different from ranges indicated.
U6 pin 29 indicated 70-90 k i have 96,5 k
U6 pin 30 indicated 70-90 k i have 96,7 k
Is there anyone (i know he is out there ;D) who can tell me if they
are unacceptable
Stan, I dunno if it may be related, but I recently had a dead spot in the RF
gain
encoder. It was recommended that I do a recal (using 20M) with the XG2 and

of the utility. An earlier version had a bug where the settings were not saved.
Cured
my problem.

I would be very happy to just have a live PITCH control, as has been

received signals as you vary their pitch, without changing their
location in the passband. That would be much better than having to

The pitch function that you say you want - change the pitch of a
received signal - already exists, just turn the VFO knob, it will change
the pitch of the signals which are being received. Normally one would

Check to be certain Control Board RP4 is well soldered. If so, I would
believe all is well. Your readings vary by less than 10% from typical,

Not true. A speaker with lousy response can create distortion and
emphasize QRN, making CW harder to copy.

Wow Don, you really really missed his point. He's trying to say that the Pitch

when you push the button that sets the pitch freq. that the tone isn't

Contrary to my earlier statement my K3's main RX does show an RF gain

by the CAT protocol):
