Gregg, I would suggest looking carefully in the IF filter area. You found one bad solder joint, so another one is quite likely. The last one I worked on with similar problems had a bad solder joint on the SSB board at one of the 3 pin headers - which reduced the signal getting to the IF amplifier a LOT. Remove the SSB board and put jumpers into the 3 pin headers (jumper from pins 1 to 3) and see if it comes to life again - if so, the problem is on the SSB board.
73, Don W3FPR ----- Original Message ----- I've got a Rev A K2 (#529) that a friend brought to me to upgrade to all the Rev B mods ect. Before I did the mods I fixed some problems....low audio out (bad solder joint) and other minor probs. So before I started the upgrades it was working. Here's the problem now. The radio works great except for the following on receive: Very low recovered audio and low S meter reading................ I'm looking in the preamp/mixer and receive VFO area....I found on the VFO (Q18) the original owner put another 1N4148 on the bottom of the board across D13 in the opposite polarity....was this something I didn't hear about (with or without I still have the problem). I've checked the voltages on the VFO and Buffer and the preamp and everything looks good. So does anyone have some ideas. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
