Re: [Elecraft] K1 construction manual for Rev D and earlier

[Sam Morgan]

try here:
http://www.elecraft.com/K2_Manual_Download_Page.htm#K1
look for:
K1 Manual (.pdf)(5.1MB) K1 Owner's Manual, Rev I, April 15, 2011

then look on page 48 of the pdf (page 47 in the manual)
where it says:
quote
Transmit Offset Adjustment
Locate the offset test switch (S2) on the bottom of the RF
board. Place it in the TEST position. You should hear a tone in the
headphones; its pitch is equal to the transmit offset. If you don’t
hear a tone, try rotating C13 (back left corner, near the key jack).

Using the menu, locate S T P (sidetone pitch), and go into edit
mode to turn on the sidetone. You should now hear two tones: the
sidetone and the transmit offset tone. If the sidetone is very weak
or very strong compared to the transmit offset tone, use the S T L
menu entry to adjust the sidetone volume. Note: The receiver is
muted in S T L edit mode, so you'll have to return to S T P after
making any change to the sidetone setting.

Adjust C13 so that the transmit offset pitch is as close as
possible to your selected sidetone pitch. The two will seem to
merge when the pitches are matched.

Exit the menu, and set S2 back to the OPER position.

If necessary, use the C A L menu entry to calibrate the
operating frequency on transmit (see page 41).

Ken,

Sorry, I do not have an older K1 manual.  If anyone has a pdf copy, I 
would like to have it too.


I can tell you how I set the TS offset on these older K1s, but it does 
take a few extra pieces of gear.
I use a signal generator (another transmitter working into a dummy load 
will do) to produce a signal and receive it (zero beat) at the K1 
sidetone pitch on both the K1 and a monitor receiver.
Then without touching the K1 VFO or the monitor receiver, I transmit 
(into a dummy load) and set the TX offset so the pitch is the same on 
the monitor receiver.
I do play the monitor receiver into the soundcard and view the audio 
pitch using Spectrogram to make certain the pitch is the same, but you 
can do the same by just zero-beating the signal in the monitor receiver 
- tune the TX offset capacitor until it is zero best.
