With the generous help of Gary and Wayne I have fixed a problem that has been
bugging my KSB2 since I built it.
I had been getting a variation in the amount of mic audio needed to trigger the
VOX. Also very intermittently (with VOX selected) my K2 would go on to
transmit
and stay on until I
Mint condition KX1 with 30 meter module and antenna tuner, also comes with a
MFJ 4110 external ac supply.
All documentation including a Nifty Manuals laminated cheat sheet, shipped

Think of the antenna and everything connected to the ground terminal of
the KAT100 -- including the counterpoise -- as an off-center fed antenna.
When you removed the counterpoise, you moved the feedpoint. This changed
the impedance seen by the KAT100 ... 73, Vic, K2VCO
Thanks Vic, I get it
Thanks to those who responded to my question when I
got carrier on keyup in SSB mode. I had neglected to
remove C-167! I removed it, set the carrier balance,
and immediately made my first contact on 14.300,
the Maritime Mobile Service Net at 5 watts.
One problem remains, and that is the dial

Take a look at the K2 dial calibration article on my website

When I calibrate my kx1 I get different values for the
dds cal depending on the band:
40m -28
30m -23
20m -17
BFO cal is fine at -.10 I used USB and a spectro type
program to cal on the 1000hz top of the minute tone
from wwv (5.0 and 10.0 15.0) also checked against CHU
and it is similiar.

The long-route airline aircraft of the era often had a radio operator on
board. He had to be licensed the same as a merchant marine radio officer,

Thanks Vic, I get it now: the method that I am using is valid only when the
antenna is 1/4 wl or less. Since my EFW is 86 feet, it would only
be useful trying this comparison on topband where a 1/4 wl is roughly 125

I used to copy press off the air in the 50's. As the lone Flight Test ground
controller for Lockheed Aircraft Service, it helped fill in the time between
condition checks with planes aloft and preparing meteorological reports. We
used both HF AM and CW in those days. The press was sent from

Hi Ron,

broadcast in the 1970s at somewhere around 30 wpm. It was great practice,
and interesting too.

Ron and all,
Are you aware that reducing the RF gain will reduce the AGC action as well.
Folks who want to try it may be surprised how well copy can be made under
QRM conditions with the AF gain at full and the overall gain controlled by
the RF gain.
With this technique, the residual AGC

Well, YMMV ... but I'm sort of with Ron. I like to know what's going on
around me, and if I want to really dig in and pull someone out of the
noise, I know I can do it (well, sometimes!). I retired from
communications engineering, and I accept all the theory for channels

Earlier in this thread I mentioned that the old RCA coastal marine station

The newly formed North American QRP CW Club is sponsoring a new award
for the coming year. Since 2005 is a mere three weeks away; now is a
good time for all you folks begin thinking about it.
The award is The QSO a Day Award; and it's purpose is to increase QRP
CW activity on the air waves.

I am a bit tired from hiking out a Noble Fir this morning. I must have
