2020-03-31 Collecting Novelty Transistor Radios

Also FB group Vintage Transistor Radios Collecting novelty transistor radios has a few drawbacks, the most obvious is that they are much rarer than regular transistor radios. Generally the new novelty transistor radios are much more expensive then a regular radio due to their limited production. The customer who just wants a radio is going

2020-03-29 AM Osc + Modulation + Buffer

This is from Electronics Illustrated Projects 1968. It shows crystal sockets, but instead a RF coil may be used and its value will be about 220 microhenrys. And C1 and C2 will have to be changed to bring the frequency down to the AM band. The germanium transistors are no longer available so silicon transistors

2020-03-10 Simple AM Band Antenna Tuning Coil 240 Microhenrys

The standard ferrite antenna loopstick for a 365 pF tuning capacitor has an inductance of about 230 microhenrys. This in combination with the tuning capacitor tunes across the full AM broadcast band. It’s useful to be able to wind your own inductor so it can be used for an antenna coil, a trap to attenuate
