    I thought I put a message on this thread yesterday, but if so, it has disappeared.
    So here goes--this information is from "Wireless For The Warrior", Volume 4.
    This book has about 6 pages on the "Pipsztok" radios used by the Polish Armia Krajowa (Home Army), and a number of central European resistance groups, and about a page and a half on the AP 5.
    the Pipsztok radios date from the late 1930s, when the Polish Second Bureau ordered HF radio sets from a small company named AVA in Warsaw. As you know,
    AVA was also involved in making the Polish copies of the German Enigma machines.
    In September 1939, AVA was evacuated, first to Romania, then to France. The chief designer for AVA, Tadeusz Heftman, took the drawings, specifications and a Pipsztok prototype with him, and got safely to England in 1940. He went to work there at the Polish Radio Centre. At the Centre, they built A 1, A 2, A 3 and AP 4 sets, mostly for the British SOE.
    The AP 5 appears to have been manufactured in 1944; it differed from the earlier sets in that it covered the spectrum from 2MHz to 16MHz in three tuning ranges (most of the earlier models only operated up to 8MHz). The transmitter uses a 6L6 tube; there is a built in Morse key. The radio could be powered from mains or a vibrator power pack or a hand generator. I collect WW2 spy radios and I don't have one--I'd like to buy this one!

    Is that the infamous Polish radio set that sent large chunks of information in compacted packets/bursts ?

    Rag,
    There had been rumours of a new secret radio set used by the Poles to send info in packets at high speed.

    It would be interesting to see if anybody doe's have any solid information about it.

    Cheers
