manj@brand.usc.edu [B.S. Manjunath] asks:
I have an interesting and perhaps a strange question.
Is it possible to receive AM on SW ????
Well, the reason I am asking this is: I have a small sw receiver.
While playing around with it, I noticed an interesting thing. There
is one station which appeared on ALL SW bands at the same physical
location on the dial (the radio has analog tuning).
After some investigation :-) I discovered that the station
indeed is a MW station broadcasting at 790 Khz.
(etc.)

I don't know if this is the same phenomenon, but I have a cheap DAK
radio (really an Emerson) that has such poor image rejection that you
can receive local *loud* AM stations at many points on the SW bands.
I don't have it nearby to check whether it's at the same dial setting
in each band, but it's loud, it's distorted, and it's lots of places.
In a way, it's a nice additional feature of this radio that although
it only goes up to something like 22 MHz, I can get the local NOAA weather
broadcasts. These are transmitted on 162.40 MHz, I get them around 17.5
MHz! I can also pick up some of the local 2m amateur repeaters and such.
Truly a many-band radio.
If you have a good quality receiver, then I don't know what the answer
is but if, like me, you paid $50, then you have to expect these things :-)
[otherwise it's not really a bad radio]
