[Elecraft] Problem with 15 Meters

[Don Wilhelm]

Cory,

Your problem is with the 2 band board only - the K1 works on 80 meters, 
so the base K1 is working OK.

Yes, it would seem that you have a problem with the bandpass filter - it 
should not attenuate the signal as much as you reported.  Check all the 
components, and especially check the soldering - in fact, check the 
soldering at least 3 times with a break between each check.  If you can 
have another pair of eyes look it over, that may reveal something that 
you missed.  If you are not certain what a good solder joint looks like, 
I refer you to the soldering tutorial on the Elecraft website Builder's 
Resource page (or is it application notes, my memory fades...).

73,
Don W3FPR

Coils L3 L4 L7 and L8 tuned fine. From the RF bandpass filters the RF coming out is half of what is going in. Has anybody had this problem before??
