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!

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. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
