Tom,
Please explain the "could not get a reading" - does that mean your DMM
reads zero ohms or infinity? Infinity is the same as you see when the
probes are connected to nothing.

Hello Don, on power up I am still getting Info 080 message and garbled
frequency display (and no relays are clicking), alot of the menu functions
show up correctly though, I checked the following as you indicated: RF Board
U1 is oriented correctly and no pins are bent, jumper is set for INT on
P7,pin 1 is soldered correctly on Front Panel U1, and my soldering is done
correctly so far everywhere after re-checking all of it, I did some
resistance checks on the control board, could not get a reading on the
following: p2 pin 1, u3 pins: 8,13,14, u8 pins: 2,15,16 (got readings on the
rest of the control panel test point checks)...for resistance checks on the
front panel board I could not get a reading on the following: u1 pins 4,
13-40, j1 pins: 1-7, 9-11, 13-14 (got readings on the rest of front panel
test points); for RF board resistance checks I could not get readings on the
following: u1 pins: 4,9,10,28, R1 and R2, (got readings from rest of rf
board test points)
thanks for your suggestions, anything else I should try at this time?
thanks and 73,
