E 53b
(Ulm) - Luftwaffe VHF communications receiver (Ln 21001-1).
23.7…70.0 MHz, A1 / A3 / F3.
Using the same type of tubes all over -
RV 12 P 2000 pentodes. Some E 53 models
were capable of television signals reception. Manufactured

E 53
was designed by Telefunken as part of Luftwaffe contract for
four receivers (E 51, E 52,
E 53, E 54) all
similar in appearance, to cover all the usable frequency
spectrum up to 120 MHz. E 51
"Leipzig" was a double-conversion superhet
covering Long and Middle waves. But Wehrmacht already had
enough receivers for frequencies below 1.5 MHz. This is
why only E 52 "Köln" and E 53
"Ulm" were approved for service. E 54
"Kulm" has never seen production because
WW II was over.
