Even the second receiver has a big influence on how your signal sounds.
At present I am building my version of a wideband monitor receiver designed by
Ian G4COL, and featured in the RSGB Rad Com of November 1990.
As this has no pass band filtering to colour the received signal, combined with

Oops, I said KDSP2, when I meant to say KPSK2, my name for that tight little

use for sideband ever since. But I did struggle with my KSB2 recently

Hello group,
I'm not sure where else to ask this question. I can't seem to get anything
but an answering machine at the Kenwood Amateur Radio Tech support Center.
While waiting for a new K2, I would like to get on the air (after a
considerable absence) with an old (but very good) TS-820S. The

My best guess is that you have reversed the wires in SPK-J1 - The connector
on the cover. OR you have reversed the ground (earth) on SPK-J2 - The
speaker jack on the rear of the cover.
Remove the cover and set it away from the base, Disconnect the internal
battery if you have it, just

Hello all (again). I'm attempting to align the VCO and am having
trouble making it lock on all bands or get to the right voltage range.
I've verified all components on the board and touched up the solder

paths/continuity), but nothing
Tom,
I don't know about the TS-820S, but if the finals are run in linear mode for
both CW and SSB, you can safely reduce the drive without hurting anything.
If your TS-820 has a drive control, I would think it would be safe to use it
to reduce the drive.
OTOH, (just as a cautionary note) a few
Tim,
Check and re-check the capacitor values. From the bands that seem to me to
have strange voltage readings, C73 (should be 47pf) and C74 (should be 20
pf) are the most likely culprits.
Other things to check: be certain the menu parameter for D19 is OFF - check
the relays K13, K14 and K15, set
I'm trying to get TRX Manager to talk to my K2 over a

Thanks Fraser, Don Rick,
I was hoping this would be the case.
As I mentioned to Fraser, thanks to the Elecraft crew and all the users.

me out!

I bet a cup of coffee it is a K2 like rig. It will cover 160-6M standard.
They want to compete with the Argo, so I think the new offering will have

Am I even close?

Ken,
Since you can see the display - and it seems to be proper, many of the front
panel signals must be correct.
I would look closely at the SR CK signal on the control board and on the
front panel board since this signal is common to the circuits that you
report as failing. Check the

I recently purchased the K2 PLL Temp Comp mod kit, and it came with Rev
D (3 Feb 04) instructions. A couple places in the instructions mention
replacing L31 (originally 10uH, which my rig has) with a 12 uH inductor.
Yet the parts list states it should be a 10 uH, and I was shipped a 10 uH.
Mike,
Yes, ignore that inductor change. The inductor necessary depends a lot on
the crystal that shipped with your kit, and the proper value has changed
from 10 uH to 12 uH and back a few times over the life of the K2. Put in
the 10 uH (or re-use the one that is currently installed) and wait

Roland,
That sounds like the behavior one would see if the control board is not
properly plugged in.
Since you received the kit partially built, you should first gain confidence
in what the previous builder has done. I suggest that you go through the

The two blue pots on the audio filter seem to offer a great range of audio

However with the pots and software, I cannot get on effect I want.
