Steve,
SW>MOULD
SW>Someone asked me what the letters MOULD stood for, I've lost the
SW>original message but here's the info hoping it get's to the right
SW>person.
SW>Ministry of Defence National Home Defence Repeater Network
        It was me.  I have a listing of a few users of the VHF-Lo/Mid
        band (30 - 88 MHz) for the UK in an old issue of Popular
        Communications.  There is a lot of MOULD stations in the 60 - 80
        MHz area and I wonder what they were for although I did know
        they were some sort of military communications network.
SW>Appears a bit of an anomolly if this is from the cold war era
SW>from what I can gather the electromagnetic pulse from a nuclear
SW>explosion would but all but the most hardened semi-conductor
SW>devices out of action, still knowing our military maybe they were
SW>still using valves, before any one says it i know some of the most
SW>hardened devices still use valves
        Over here, there is a radio network called GWEN for Ground Wave
        Emergency Newtork that uses longwave frequencies in the 150 -
        180 kHz area.  I do pick them up a night every so often on my
        longwave band.  They sound like a hush noise which changes pitch
        on the radio.  I seem to receive most of them in the 160 - 175
        kHz area.  LF doesn't seem to be affected too much by nuclear
        blasts.
        As to VHF, there are some problems in communications after a
        nuclear strike, but things settle down relatively quick.  As to
        EMP affecting equipment, tubes are the best bet but some do say
        that solid state VHF/UHF equipment fares pretty well too
        although I would take steps to put my radios and scanners in a
        grounded metal box.  B-)
Chuck, thanx for your answer....
