[MRCA] Modern AM

[Lou Ribble]

Rob,
	My PRC 174 had excellent AM capability. Unfortunately I no longer
have it. I used to check into the OMRN on 3885 AM & it always worded FB.

I want to do a demo of a WWII radio with some current US military.  What
manpack radios in current use could I tell them to bring, that would do an
AM equivalent on 3.9Mc?

Line of sight(hollering distance) is all we need to do.

PRC-138 comes to mind.  It transmits AME, upper sideband with full 
carrier.  I'm not sure how it's receiver behaves.  Your off-freq. 
transmitter may result in an objectionable heterodyne if the thing 
receives in SSB mode.

Hi,
Does anyone know what the orc-138 does in receive in AME mode?  Does it
turn off the BFO?
I am interested to know if it will satisfactorily receive AM that is not
exactly on frequency, but in the passband.
Thanks, Rob

Thought just about anything in the Harris Falcon line including the RF-5000
family of radios has an AM capability usually with a wide filter for the AM
mode and full DSB with carrier in the AM transmit mode although its AM
that's still developed at low level. Not much experience with the new stuff
but know from experience that the Harris stuff built back in the seventies
and eighties suffer from stupid wide IF filters in AM receive that are an
issue.
