K2 S/N 4226 60m VCO value

[Kenyon Cox-2]

Greetings All,

Finished up the 60meter module, and ran into a "hitch" during the 40/60
meter alignment (p. 13).

VCO voltage at R30 was only 0.87 volts at 5300.  At 5450, VCO was > 1.0
volts.

Re-checked the VCO numbers for other bands, and at 4.0 MHz, the Voltage
was at 6.0 volts.

After checking components (OK), and solder joints (OK), and perusing the
archives, arrived at the decision to adjust L30 to get the 1.0 volt
(minimum) at 5300.  I then checked other VCO values for the band(s)
edges, and the max VCO was 7.0 volts at 4.0 MHz.  

L30 was adjusted about 1/4 turn clockwise (about where the factory had
it, originally).

It _appears_ that this set up is OK based upon what I read in the
archives, although no one has commented on this problem with addition of
the K60XV.

Comments?  Questions?  Is My K2 Ruined (IMK2R) ?

Thanks,

Kenyon Cox

Kenyon,

You did it just the way it is supposed to be done - congratulations.
Adjusting L30 is mentioned in the 3rd step of the 40/60 meter alignment on
page 13 of the K60XV manual.

73,
Don W3FPR
