[NJARC] FM Station Progress

[Matt Reynolds]

It's still amazing to me that an entire electronic device like an FM transmitter can be made so cheaply.  I can't imagine what those of you who have been in the hobby for years think either, when individual components like transistors cost a ton of cash.


It's getting close to looking a lot like black magic.

FM Followers,

I hot-glued the transmitter to a piece of perf board:

Mounted it in a Pomona box that surely cost 3 or 4 times as much as the TX:

Power and audio via USB from my office PC.

Hooked it to my homebrew disk-cone antenna in the attic.  (aprox. 100 feet of coax.)  Quick survey showed it covers the neighborhood for about 100 yards before co-channel interference from WRHU, in Hempstead, 25 miles, 500 watts, takes over.

I'm declaring this a success.
