[Milsurplus] [Boatanchors] KWM-2A Problems

[Al Parker]

Hi Jeff,
	I'm far from an expert on the KWM-2A, but having owned 2 plus a 32S-1, 
have had a little experience (often greatly enhanced by the experiences 
of others).  I'm fussing along with a 32S-1 right now, helped out by others.
	It appears to me that the alignment of yours was carried out with the 
kc tuning knob set at zero, as on all the lower bands your output is 
best at the low ends of the ranges.  IIRC, you should set the kc dial to 
100.  Your 3.4-3.6 output is low, but I've seen that on mine, too.  I 
think it's a Q problem of the ckts on the lowest freq., not much can be 
done.  20m looks pretty good.  Low on 15 & 10m could be due to weak 
finals or driver tube, but might come up a bit doing a full alignment as 
detailed in the manual.  Be sure to read and follow all the manual 
steps, IIRC, the higher freq. bands, above 20m, depend upon the 20m 
tuning, so it must er done first.  There's a caveat in there to not 
touch one slug adjustment until "later".   That tripped me up once.
	I've seen ~120w out on some bands, but basically feel that 95-100 is 
acceptable.
