[Elecraft] KSB2

[Ron D'Eau Claire]

Fred, take care not to put too much solder on the pins of the crystals when
you install them in your new KSB2. One of the most common reasons for low
gain is a bit of solder that puddled around the pin under the crystal can
where you can't see it and shorting the signal path to the can. Remember,
those are plated through holes, so when solder melts and flows on the bottom
side, it's melted and flowing on the top side under the crystal too!

Although I operate almost no SSB, I built the KSB2 for my K2 (#4398) 
late last year so I could use the K2 for RTTY contests.  It seems to do 
everything a well conditioned KSB2 should do except it exhibits about 30 
dB loss through the on-board filter.  Thus, the SSB output from the K2 
is in the milliwatt range and the RX level drops very noticably with the 
OP1 filter selected.  I haven't had the time to figure it all out, and 
it's a bit tough since my test equipment is limited to a DMM, old Tek 
scope, and a very old service monitor.
