It is a transistorized radio but is about the same width as the NCX-3 that I have it sitting on.
I liked the radio because of the very professional looking main tuning dial and the band spread tuning dial.
The receiver was also made as an HE-30, but the KT-320 was a kit that the buyer had to assemble. These radios were made by Trio Radio of Japan. The HE-30 was introduced in 1961 and this KT-320 came out shortly afterwards.
This is a really nice radio that was built from a kit.
It looks like the person who built it did an excellent job. The radio plays and sounds great on all bands.
The radio was made from 1963 to 1972 and this one looks like it is brand new!
It is a 5 band radio with bandspread control on all bands. Band 1 covers 200 to 400 KC. Band 2 covers 550 to 1800KC. Band 3 covers 1.8 to 4.8 MC, Band 4 covers 4.8 to 12 MC and Band 5 covers 12 to 30 MC.
