hello all,
I have a 22b here that i was having an audio issue with, after transmitting for a short time, the audio would get really trashy, like off freq trashy.
so, i went over the whole board and touched up every solder joint on the board. i did fine 3 cracked solder joints that was the cause of my audio problem.
however after i got done with that, i plugged it up and NO AM RX!
ssb,fm all rx fine, just AM i have no RX and no white noise in the speaker.
I thought that i had some solder touching that shouldn't be somewhere in the radio, so i took out another 22b i have here and compared the 2.
I can see nothing touching (i may be overlooking) but i have looked it over several times.
My question is, where in the radio do i need to look, or what part/parts do i need to replace to fix the NO RX on AM only?
its apparent that I'm in the wrong part of the radio, because i ha ve already replaced,
c102,c103,c58,ic11,q29,vc1,c21,r22-23, you get my point..
does anybody know what causes the RX on AM to not work at all? while letting ssb and fm work fine? this is a really great radio and would really like to get this fixed, but I'm out of ideas and places to look, so I'm hoping that somebody here can point me in the right direction. |
