hi Ron - ol' #525 has been getting pretty scratchy lately, and it has the AF Pot Mod. I guess they just get old and scratchy like the rest of us...;-)
I found my misplaced XG1 the other day and went around measuring rigs. #1250 was singing along at MDS=-136dBm, but #525 wasn't close (haven't used it since Field Day, I'm afraid). After a bit of poking around, I found a marginal solder joint had finally gone bad in the T-R switch (RFC2). Some new solder and good as #1250! cheers! - jeff wk6i At 07:54 PM 1/3/2006, Ron D'Eau Claire wrote: >>From the serial number you might consider making the audio gain pot mod >while you're in there if it hasn't been done yet.
