Re: Another "Pantry" Rig for the IC-allergic
I'm thinking of an experimental pantry-transmitter using one of the crystal-oscillator modules driving a VMOS FET, with something like a "LT700" transformer in the drain-lead to supply modulation.
Turn the modulation off and you've then got a nice 1MHz frequency-marker too!
One thing that's often puzzled me is why nobody seems to use a ferrite rod as the antenna on a pantry-transmitter. If the receiver you'll be using the TX with has a ferrite-rod I'd think that a similar rod in the TX would give better (magnetic) coupling than the traditional bit-of-dangly-wire.
