[Elecraft] K2 s/n 3602 had it's first completed qso ...

[Jan Reidar Oeverland]

...   on 40m  the 6  Oct 2003.   It was  my first  completed  qso too,
ever. G3CSY,  Ken, answered  my cq. He  showed a tremendous  amount of
patience with my untrained fist!

I've done the �final� C22 alignment  against RWM in Moscow, as I don't
hear  the WWV.   One  question: Adjusting  the  capacitor yields  only
negible  changes  in  frequency,   untill  a  large  (~2kHz)  step  is
encountered.  The CAL FCTR reads  a frequency far from the target.  To
temporarily fix  this, I soldered  a 15pF cap  across C22.  It  gave a
+320Hz  offset against  RWM ---  which is  the closest  I get  with my
junkbox  parts.  C22  now shows  the  same erratic  behaviour, but  in
another frequency range.   In the parts list, the  trimmer is supposed
to be unmarked, or green/red  dotted.  Mine is red dotted, but without
any traces  of green.  Should  I consider C22 �dead�,  out-of-range or
are there any other possibilities?

The manual states that the RF-probe  should give a DC reading equal to
Vrms.   The probe  comes with  a 4.7M  series resistor,  that  gives a
reading  equal  of Vrms  only  if the  DVM  has  11M input  impedance.
However, my  DVM has 1M  input impedance.  The ratio  is (4.7+1)/1=5.7
which  is approximately four  times 1.414  and not  close to  Vrms.  I
haven't seen anything in the manual explaining this.  Unless I applied
the wrong math, a note about  scaling the series resistor to match the
input impedance of the DVM might be a good idea.

The RSGB sells  a book on propagation, �Your  Guide to Propagation� by
Ian Poole.  Does anybody know if it is �good� and �useful�?
