K2: Alignment and Test Part II

[Linden, Mike (BRC-Hes)]

  After setting L30 for 6v at R30 at 4 MHz, I am reading 1.53V at 3.5 MHz.
While this is above the 1.5V limit, is it a little bit too close for comfort
or is it OK? The voltages for the other band edges are all well within the
specified range.

  Also, when adjusting the filter BFO values I found that the BFO frequency
being displayed would sometimes slowly alternate back-and-fourth between two
close frequencies. I believe this is because the frequency counter is being
used to display the frequency and that this is normal. Is this the case?

  Thanks, Michael N9BDF

[G3VVT]

The VCO voltage reading is within the tolerances quoted by Elecraft so is  
normal.
 
However this is not the whole story as you have to look at the results for  
all bands rather than just this one and ensure that they also fall within the  
stated limits. On my K2 on 40m with 80m set as advised in VCO alignment (P61)
in  Alignment and Test, Part II, 7000kHz was below the quoted figure of
greater than  1.5V. This meant a juggling act to balance up the readings.
 
What I ended up with was:
 
3500kHz = 2.40V
4000kHz = 6.85V
7000kHz = 1.50V
7300kHz = 2.95V.
 
On all other bands the VCO voltage readings were well within the tolerances  
of greater than 1.5V and less than 7.5V.

Bob,
 
  I agree... In my case, the voltage at 3.5 MHz was the ONLY voltage that
was anywhere near a limit.
