[Elecraft] K3 NB Success in NB !

[Mike Smith VE9AA]

YAY!  With a little coaxing from the guys on this list and others, I felt
very brave and partially disassembled the radio and reseated the KNB3 board
and reinstalled.

No luck. Same symptoms.

Phooey !

 

So I decided to go for broke and swap the KNB3's between the main and sub
receivers.  Looking at the manuals, it didn't look to be too bad (I did it
twice actually)

and found that now both the main and the sub receivers work with the
IF-NB's.

 

I do note something a little odd, in that when I turn up the IF-NB settings
on the sub-rx (which now has the questionable board) that sometimes I get a
frying sound.

It's repeatable.  I also saw that once and only once on the main RX with IF
NB engaged.  Maybe that's what it's supposed to do if it's maxxed out.

 

I haven't had a real solid test, but just ran it through a few bands and a
few different settings,(just a few minutes) so by all means I don't have it
dialed in, but when an electric fence pop goes from a solid s5 to perhaps an
s0-s1 I can tell it's working. (before, almost nothing was happening)

 

Also, no more flashing NB on either the main or sub receiver. (so far,
anyways)

 

Thanks everyone - couldn't have done it w/o you.

 

I hope that's it for now.  The SUB-RX is not exactly "easy" to come out.
(especially since I wasn't the one to put it in, nor had I ever had a K3
apart.

 

What a great group here.
