On around 1/1/04 I began work on the construction of a
1924 superhet using the QST articles from June, July and August as a
guide for my radio. On 1/8 I got a receiver working using a total
of 5 #201A's. It receives from 3 - 6 Mc as it sits, but only
hears AM being I dont have the separate BFO built for it at this time.
The radio is currently sitting on 2 breadboards where I'm testing some
of the circuits.
The superhet as of 2/4/04 Front panel view
The mixer & oscillator. The oscillator is on the left.
Next tube is the mixer, followed by 2 IF amps
The IF and gridleak detector. This is a 2 stage IF, the white
disks are the IF
transformers, hand made. Last tube on right is an audio amplifier.
