[Elecraft] Receive Problems

[Gregg Lengling]

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.

Thanks in advance.
