Heathkit Model GC-1A Mohican
This radio is a 1960's Heathkit Model GC-1A Mohican portable receiver. It is powered by
8 flashlight batteries or by an ac power supply. It is one of the first transistorized
general coverage receivers. The radio tunes from 550 kHz to 32 MHz in 5 bands. The circuitry
has 10 germanium PNP tranisitors and 6 diodes.
I did not build this radio. When I purchased this radio, it was quite dirty, but it worked.
However, I had to replace the AGC filter capacitor because it was open and caused the
radio to oscillate when receiving strong signals. Also despite the "calibration" sticker
on the rear, the radio did not read on frequency. I have calibrated the radio on all 5 bands
and all are reasonablly calibrated to read the correct frequency according to the dial settings. The radio uses high side local oscillator injection on the 4 lower bands. Band E uses low side local oscillator injection. The local oscillator must be adjusted for this
condition in order for the dial to be accurately calibrated. The radio is quite sensitive and
receives well. The radio has a variable beat frequency oscillator (BFO) for reception of
CW and SSB signals.
As you can see by the above picture, the radio cleaned up nicely and looks great. I used
car polish to make the metal case shine and look almost new. There are a few scratches on the
top, however. I also had to replace the feet on the back of the radio. Two of the original
feet were broken off, one was broken and attached, and one was in reasonable shape. I replaced
all feet with white round circular feet pirchased from a home improvement store and attached them
using the original screws.
Below is a picture of the top side of the chassis.
Below is a picture of the bottom of the chassis. There is a sticker inside where someone,
presumably the builder, wrote a date of 3/1/63 that is probably the date it was built.
The workmanship was good.
Below is a picture of the front of the radio. The signal strength meter is on the top left.
The meter pointer is at the top (maximum) signal strength when the power is off. Weak signals
will cause the pointer to be near the bottom of the meter. The radio has all original knobs
and the chrome on all the knobs is in good shape. The radio has a bandspread calibrated
for the 75/80, 40, 20, 15, 11 (CB) and 10 meter radio amateur bands.
Below is a picture of the rear of the radio. The ac power supply accessory is behind the panel
on the top center. When using batteries, the ac power supply is removed and a similar
panel with a battery holder is installed. I do not have the battery holder.
