Yes, that's it, the one for sale in the second link is what I have, I don't remember paying that much, but maybe I did. It works just like advertised, that is, very well.

RE: [AMRadio] NPR, one solution for lousy radio
The ramsey stuff don't work worth a crap. I got a real nice 1 watt synthesized transmitter with a digital frequency readout, nice stereo separation and good fidelity. With an outside antenna, it goes blocks, never tried to figure out just how far. 1 watt with a good antenna should go miles. I tried cordless headphones, the ramsey stuff, and other FM transmitter kits, and the range was lousy. I like to wander around while listening, go out back of the house and smoke, make some tea, etc (plenty of old buzzards on the air!). The transmitter was about $100.00 but its very well made, and very clean. Its not a kit, and has a very large heat sink. It has no case, just the display mounted on a circuit board, you push buttons to change frequency and other options, the back of the board holds the heat sink.

Re: [AMRadio] NPR, one solution for lousy radio
The best Part 15 FM transmitter kits are the ones I've purchased from DC ELectronics http://www.dckits.com/stcast.htm I've used their mono unit (PLL-MONO $59.95) in situations where I need maximum range, and the stereo unit (PLL-SFM $79.95). when two channel audio is important. Both are PLL synthesized with on-board keyboard frequency entry. Nice kits... Steve WD8DAS [EMAIL PROTECTED] http://www.qsl.net/wd8das --- Radio is your best entertainment value. ---

A number of years ago, Don, my dad bought a small phono-oscillator type thing, where you could specify the frequency of the crystal controlled oscillator. He chose 145.00Mc, because back -then-, that was considered a simplex frequency (sometime in the early 80's). It was built in the covered part of a standard PL-55 jack, with a 'larger-than-normal' covering where the terminals normally connected. The PL-55 was plugged into a headphone jack, and the audio was re-transmitted on the specified frequency. Dad used it to monitor his 40m frequency via his Heahtkit 2m HT. A crystal controlled phono oscillator shouldn't be all that hard to construct. 73 = Best Regards, -Geoff/W5OMR
