Whoda thunk???
The C21 was a superheterodyne with a 5.0 to 5.5 MHz wide IF stage, fed by the RF input and the crystal oscillator for each band, and a product detector on the AF board that uses the VFO as the “BFO” to carry out product detection. It is NOT direct conversion.
I had always assumed that the C22 was a repackaged C21 with digital display. WRONG!
It is indeed a direct conversion radio. It premixes the PTO with the crystal oscillator for each band and shoots the result (which is right on the revive and transmit frequency) right into a mixer which direct detects signals, then on to the AF stage! What a downgrade compared with the C21!
WHAT A DOWNGRADE TT made to produce the C22!
If you have a choice, get a C21!
