Nice AM Station  Time owned: 0 to 3 months
The Cheyenne & Commanche are mobile sets manufactured by Heathkit in the late 50s. These small units measure 12.25"W x 6.25"H x 10"D (less knobs & rear connectors). What makes these radios a pleasure is being self-contained & compact with a seperate power supply using either a 12 volt DC version or the Heathkit Utility power supply called the HP-20. Later power supply models with the 250vdc or 300vdc low B+ selector switch can be used in the 300 vdc output position. The construction is solid with ceramic switches & point to point wiring that does not include the unreliable, subject to heat cycling printed circuit boards used in later Heathkit models. The transmitter has a built-in VFO & a 'spot' switch for aligning the frequencies on both radios. The transmitter is a low level, screen modulated type that produces surprisingly great sounding audio- no modulation transformer & associated push-pull tubes required. The output is 8 watts carrier.

The receiver is surprising frequency stabile like the transmitter after the warm-up period. Just enough front panel controls are provided for complete flexibility. Antenna Tuning, RF & Audio gain plus a variable BFO are included. The radio also has a Product Detector and a 3Khz bandwidth crystal lattice filter for good selectivity. The crystal filter is excellent for crowded band conditions, superior to many more complex radios from the same era. The receiver is reasonably sensitive, however I would recommend changing the 6BZ6 tubes with 6JH6 type for better sensitivity.

The radio set has received good audio reports on 10 meters & can 'hear' about any signal without a reading on the 'S' meter- a good indicator of a sensitive receiver. The Comanche & Cheyenne are highly recommended. I would rate the set about a 4.5 if the site had such an option. The 'fun-factor' is a 5.0!
