Yes, Sandy. The Army BC-745 "pogo-stick" is part of the SCR-511. The famous Army BC-611 "handy-talky" you mention is part of the SCR-536. The Navy also had low power battery-powered portable MF/HF sets in the form of the MAB and DAV chest-pack sets. All of these operate at about one-third watt output into a short whip antenna. They are crystal-controlled (receiver and transmitter), operating from about 2 or 3 MHz to 6 MHz. They had 5 to 7 vacuum tubes, and utilized superheterodyne receivers and plate-moodulated transmitters. The Army sets had a receiver RF amp, but short antennas. The Navy sets had no RF amp, but longer antennas. I doubt there was ever much DX with these sets. I recently fired up my BC-611-F on 3885 kHz and heard a surprising number of AM stations at night. What would the ERP be for .35 watts on 3885 kHz going into a 48-inch whip, handheld? :-) Mike / KK5F ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
