[TenTec] LW receiver

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

Martin,
I suspected this was the case.  Thanks for your response.  73 and Happy New
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
