IHM-171. 1938 5 inch tabletop prototype. The I could mean
"initial". It is basically a HM-171 but it has an
audio channel with speaker and 7 pre-set stations. GE changed
its plans when it learned that RCA was coming out with the TT-5
television attachment. The speaker was removed, the tuner
was simplified, and the HM-171 was made. Many radios made in 1939 and
40 were advertised as "Ready for Television", meaning they
could be connected to sets like the HM-171 and the TT-5 to receive
the audio portion of TV. (Information courtesy
