I left the original rear power plug in place and found out that miniature banana plugs fit perfectly into the WW2 socketed pins. Miraculously it came to life when powered. Not intended to be used on the move. Eric Steven Raymond Ideally, capacitors should present no resistance whatsoever, but practical capacitors do present some low resistance and bad capacitors present a lot more than some resistance. %PDF-1.5 I found that all but three of the metal-can-sealed wax and paper caps (special to ARC-5 and other WW2 radio equipment, otherwise known as flower pot capacitors due to the shape of their metal cans) and the electrolytic caps needed to be replaced. Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. I wonder if the Nazi's used Hertz? What an incredible receiver, it was wide awake and operating to its original specifications once more! Excellent project. Im totally on your side generally; but its really not a crime to play around with gear like that and drill some holes. However, the Naval fleet expansion into the Pacific created communication needs that were not yet being met. I even used the receiver as a tunable IF in a science fair project experimenting with mixers/converter for 10mhz WWV. 65 0 obj My unconventional restoration of this radio followed strict rules so as to minimize the evidence of repair both inside and out yet make this radio perform again as though it came fresh off the assembly line. Oh BTW I think reforming is only a thing since ITT came out with the first thin foil caps, such that the conductive layer was thin enough to burn out around a short. I was a bit surprised at how the caps actually tested. The b version was used by the infantry until they changed to the 'c' model radio in another band. I tend to have such a bad opinion of caps made since the mid 90s though, that I figure if I leave something in that seems marginal it still might last 5 years whereas a replacement might last 3. Sound torture is nothing new. John in Texas. Mine came out of a old sheriffs car. In the hearings of 1939 were stated several points that convinced skeptics of the decision to use this system of CPNAB. It was used with the same antenna as the Fug 8. During the war this was extended to cover the majority of the occupied areas or Europe and North Africa. In the World War II context, HF/DF applied to direction-finding of radio communications transmitters, typically operating at high frequency (HF).
