Notes

Information by member Valery Gromov: "This PR-4P post-war model is existant since 1948, made by Radio Works No. 197 of Gorky-city (nowadays Nizhny Novgorod). The civil name of the factory was "Lenin Radio Works of Gorky-city" (Gorkovsky Radiozavod named after Lenin).

There is the two quite different models Air Force model US-4, using metal tubes with 6.3V filaments, and the US-4S infantry model, using glass tubes with 2V filaments. Both US-4 and US-4S were manufactured at Novosibirk Radio Works No. 590 (civil name "Novosibirsky Electrosignal") starting from 1943. It is unclear why there was already an US-4 designation for the HRO copycat in 1940 that was manufactured in Riga for the Red Army but was soon taken over by the Germans - and can now be found with the Wehrmacht Reichsadler."

Old information: AM/CW-receiver for millitary/airborne use, coverage from 0.17 to 12 MHz in five ranges. Needs Hi-Z headset. At first time radio set named US (universal superheterodyne),US-3 (in 1942), after WW2 named US-P, only last models named as PR-4 (P, R, V). Till 1941 produced in one of Moscow factories. After 1941 manufactured in Nizhegorodsk. Used as receiver-block in radio-stations RAF, RSB etc. Used motor type voltage conversion unit(Dynamotor/umformer) type RUK-300V (see foto). It works at 25,5V and supply radio tubes 6,3V (heating) and 200-220V (anode).

Net weight (2.2 lb = 1 kg) 6 kg / 13 lb 3.5 oz (13.216 lb)

Meine Damen und Herren, der Historie zur Gerechtigkeit hieß diese Stadt in der Russischen Föderativen Sowjetrepublik (RFSR) ab 1932  "Gorki", nunmehr wieder nach Entscheidung ihrer Einwohner wieder "Nishni Nowgorod". Nishegorodskij ist ein russischer Idiom  für für das adjektivierte "Nishni Nowgorod",

Mfg Hans-Jürgen Heider
