[Boatanchors] AM mod monitor FS

[Gary Peterson]

For Sale:  A Belar, solid state, model AMM-2A modulation monitor in working condition.

It was replaced by a more sophisticated and smaller Inovonics monitor with Internet connectivity.

I checked this monitor with a General Radio signal generator and oscilloscope and found it to be accurate, reading both positive and negative peaks.  This would make a nice companion for your boatanchor AM transmitter.

This Belar monitor requires an RF sample from an AM transmitter.  An outboard inductive sampler may easily be built in a Bud minibox.

A reproduction manual is included.

I’m asking $250 plus ground shipping from zip 57701.

I thought I would list it here before placing an ad in Electric Radio.
