LS-3 - Loudspeaker, part of SCR-399 and SCR-499 mobile
radio sets. Made by Hallicrafters. There were two LS-3 loudspeakers used in every mobile radio
set.
We also have in our possession, bulky and heavy BC-610-E
transmitter which was part of SCR-399 and SCR-499. This BC-610
used to belong to late Ernest Krenkel (RAEM), famous polar
radioman. Currently our BC-610 is on display at the RAEM
Memorial Museum.
