[Elecraft] K2 S/N 4226 60m VCO value

2004-11-03 Thread Kenyon Cox
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,

[Elecraft] K2 S/N 4226 Hi Cur message

2004-08-29 Thread Kenyon Cox
Greetings All,

I'm down to Alignment and Test, Part III.  Finished the 40-meter
Transmitter Alignment and the Receiver Pre-Alignment with no problems.

The Transmitter Alignment (p.77, right column) failed on 20-meters with
a Hi Cur message. 

Bumped the Cur Lim to 2.75A, and still got the "Hi Cur" message (power
output still set for about 2.0 watts).

Went ahead and broke down the radio to look closely at the RF board. 
Haven't found anything, yet.

Wanted to see if anyone had helpful hints as I look over the board(s),
and scratch my head.

P.S. Yeah, I have a Flying Pig number, but I haven't let the smoke out
of my K2, yet.
