By way of refresh....
Got the old R-195 working, hooked up a random wire and pulled in some stations but there are "issues..."
Frequency seems to be a bit off on the 2 and 5Mhz bands although close on the AM broadcast band. I can't seem to find any of the WWV broadcasts I used to get. I got some ham operators in the 40m band, AM, SSB and CW (too fast!)
But the bad thing is there seems to be something badly unstable, like the LO is cutting in and out. It doesn't drift much but if I poke at the PCBs or the shielded cables going to the tuning caps, it jumps frequency or stops oscillating(?). After numerous pokes it will eventually come back.
I'm thinking cracked PC trace, bad solder joint, deteriorated shielded cable... sure could use a schematic. Anybody?
