This converter allows reception of six metre signals on a two metre receiver. It should therefore be useful for those with single or dual band sets that do not cover 50 MHz.

The FM broadcast band was moved immediately after World War II from its original spot just below 50 Mc to the present 88-108 Mc band. Hallicrafters was one company to offer receiving converters for those who had the old FM radio sets. The offerings included a one-tube converter that fits inside a console and draws power from the audio output tube socket (using an adapter).

I designed this circuit. It can be connected to an FM tuner to play FM stations on an AM radio.

Applications ranging from frequency counting and synthesis to sensor signal conditioning require conversion of RF signals to digital-logic levels. In such situations, designers typically use a high-speed voltage comparator to perform the RF-to-digital conversion. Due to their high gain, voltage comparators typically exhibit good sensitivity but also present some drawbacks. High-speed comparators are expensive, difficult to find off the shelf, and prone to rapid obsolescence.

This little circuit is a transmitting and receiving converter (transverter) that converts a FT290 or similar multimode handheld transciever to the 14MHz amateur band. The project is a single board module that needs an external local oscillator, for example, the VHF harmonic oscillator LO for transverter project.
