Ron,
Have you tried different antennae? I have been told that if there is
oxidation where the feed line meets the antenna, it can act as a diode and
create images if the broadcast station is strong. Just a shot in the dark.
I always make sure I solder my connection and only use stainless steel
hardware.
73,
John

Year.

That would be the image of the 2nd IF = 450 kHz. TT's clever phrase
is "specifications apply > 1.8 MHz". I.e., all bets are off below
1.8. The Rx is insensitive, and as you see, image rejection is poor
-- maybe other problems, too.
I use the SubRx to listen to AM broadcast at times. Longwave is kinda
useless. Why did they enable it at all, you ask? Good question.
Competitive pressure, I suppose.
73 & Happy New Year, Martin
