Don, Great reminder. I follow your suggestions, to a fault. In the long past
not so much but the quality of the Elecraft equipment changed my practices
going back to the K2.

Many hams equate no signal band noise to receiver sensitivity. Nothing
could be further from the truth. Bob has pointed out some very good
guidelines.
For those who do not want to play with the RF Gain to simplify things,
the attenuation and preamp settings will still do a great deal to

Another complicating factor is whether you are listening in CW or CW
reverse.
I would think that the DPDT switch would be the best solution.

Chris,
The CAL S LO and CAL S HI values are as you observed.
Turn the RF Gain to full clockwise, and remove the antenna. Turn the
preamp on. Adjust CAL S LO first so there are no bargraph LEDs illuminated.

Thanks to Martin and Don.
Yep, the age setting had mysteriously advanced while in storage.
I had forgotten about the CAL submenu. Messing with the settings got me
some more reasonable S-meter action. Apparently the S LO should be greater
than S HI in normal operation.
Best wishes,
Chris
A simple DPDT switch should take care of that easily. Unless I don't
understand the tech here (hear?).

I have decided to get away from the Behringer amplified speakers and
build a box with a Lanzar subwoofer (6.5 inch - 105 to 12k - 94 db
sensitivity - 8 Ohm) for HF and several 3" speakers for the assorted
VHF/scanners etc.. The box will be sealed and I may partition the
smaller speakers into

On older K2s, there is no adjustment for AGC Threshold kike is found
with the newer ones which have a pot to set the AGC Threshold. R1 on the
control board - which is normally adjusted to produce 3.8 volts at CB U2
pin 5.
You can always set the CAL S LO menu parameter and CAL S HI to
I agree with Peter in that many hams use too much RX RF Gain and too
little attenuation. Per one authority on receiver performance, the
optimum receiver performance occurs when the no signal band noise is
about 10 dB above the receiver noise floor. Since we can't adjust the
receiver noise
I am looking for a QRP cover for K2. If you have one available, please
respond off list with price shipped to me in Franklin MA 02038. No options
needed.
Thanks.

It could also be the age setting has moved a bit, I find mine is quite

Just took out the old K2 from storage and it works great, perhaps better than
my memory of how to us it!
Seems like the S-meter is insensitive. With the Preamp on the meter works
as expected, but otherwise no indication at all, even for signals with very
good S/N.
Is there an adjustment or
Wayne,
It would really be nice to be able to reverse the sense.
That way, as one tunes 'up the band', new signals appearing 'on the
right' (higher in frequency, but not necessarily in audio pitch,
depending on sideband setting) would appear in the right ear, and would
slide to the left based on
I find the best thing for phone contesting is a ton of attenuation and
judicious use of RF Gain, combined with narrow bandwidth. No way to get rid of
the low-frequency rumble from within the passband, but the combination of the

10pf cap seem to have fixed the problem.

I am sorry you are having problems with the PLL Reference Oscillator.
Yes, there have been several reports of this same failure.
First try a small value capacitor (10 to 15pF) from the source of Q19 to
ground.
If that does not correct it, can you obtain a J310 FET locally? If so,
