Mind you, I have a couple new radios: An Eton E1XM and a Degen DE1123, plus

beats them all...

Since I'm not privy to the population of your antenna farm, I can only
speculate as to why an old Halliscratcher would beat the newer solid
state rigs. Maybe something to do with impedance and/or coupling?
In my case either of the HAM rigs generally out perform the other
receivers, especially in the presence of QRN. On a quiet occasion it
could very well be different, but those times are frustratingly rare.
Do you use a marker generator to calibrate to the approximate target
freq, or just tune for whatever shows up wherever? Back in my hollow
state days I thought the little XTAL marker box was the neatest thing on
the table, don't know what I would have thought to have seen a digital
display.

I made charts for each band. Bandspread at 100. Main tuning on known
station. Note bandspread setting vs. known station as BS is tuned
toward 0. Extrapolate on graph paper.
