[MRCA] Prc74 backpack

[walter.skavinsky]

Thank for the research guys.   I am glad that I had some people who actually  carried the radio because pictures containing the 74 are scarce and the manual is strangely silent on alot of the accessories.   I used the prc74 dipole long befor i had a 74  it works well on my kx3   i have two made up one cut for 40 meters and the other for 60.   They work well.   I purchased the whip antenba designed for the 74.  I haven't used it for the net yet.  I cannot find the length for the counterpoise.   Well time to find a lightweight rucksack .

ThanksWalt

    I got a reply from Joe Munson - WA4VAG.  Joe used these radios in
    Laos back in the day.

    

    "AFAIK, there never was a dedicated
      carrier for the PRC 74.  All we had was the light weight rucksack
      frames and rucksacks.    One guy carried the radio, another
      carried the battery, handset, antenna wire and string.  Another
      carried the keyer, and 2 spare batteries,  We just split up the
      load between some of the guys on Patrol "

      

      (Light-Weight Rucksack is a specific piece of equipment.  Google
      same.)

      

      I asked a few additional questions:

    

    They were using " the plastic box with
      the  two PRC 25/ 77  magnesium batteries.  and Yes, the GRA 71
      Keyer."

      

      Joe continued:

    
    

        "As we demostrated at GIlbert a few years ago, you may remember
        when we hauled the 74 over a couple of riidges away from
        Gilbert, Had two guys run out the dipole holding over there
        heads on 60 meters.  We talked back to Gilbert over the ridges,
        and a guy some 250 miles aqway came back to us. I think we made
        many believers obout low antenas and low power.   Basically my
        set up back some 50  years ago this October.  Usual freq was
        arond 60 meters..   Info was burst back to 7th RRFS at UDORN
        Thailand using a Wullenweber Antenna. farm.  THe RRFS, Radio
        Research Facility System was actuall a cover name one of 5 or 6
        SIGNET stations located arouind the globe using Wullenweber
        antennas.  Banks of R390A
        receiver and barracks full of listners.  
     
    You can go on web and find pictures
        of the facility in Udorn.  Google earth still shows the cleared
          off area the Antenna once occupied.  Thai military base now. 
        That  are was so soaked with Agent Orange will be years before
        anything grows back there.  
     
    We also had PRC 64s deployed out to
        operatives to send back info on CT activity."
     
    Looking forward to Gilbert again. "
