 GE Transmitter | 49.4 KB |
Suddenly it dawned on me last night that I had another Part 15 FM transmitter. About 10 years ago we bought one of those little transmitters for the sole purpose of plugging it into the stereo in my home office, where I could play Christmas records on the turntable and transmit them to the radio in the kitchen while we were making cookies! And sure enough, the little transmitter was in the drawer where I left it back then.
It's a General Electric EWT-950 FCC ID NZTSF-140. I'll attach a photo if I can figure out how to do it again.
I thought, what the heck, I'll take this out to the test field and set up all my gear again and see what kind of poop this little bugger puts out. BEsides, I wanted to do tests again on the Whole House 3.0 simply because I have a hard time believing it's THAT far over the limits.
Anyway, got everything set up "by the book" as before in a wide open field. This little GE unit runs on two "AAA" batteries. Has no jacks, connectors, or any sockets in it, just a 15 inch built in audio cable with a 1/8" stereo plug on the end. It's got the power button and a frequency select switch with thess "zones" 88-92, 92098, and 98-108. AFter you set the range switch there's a tiny tuning dial on the side. I used the Tecsun to lock it on on frequency.
So, what's the field strength you say? At the standard 3 meter test range output was 61 uV/m. As you know the limit is 250 uV/m at three meters. This is so legal it's ridiculous! This does explain why it had a hard time getting clear music to the kitchen from my office, through one wooden wall, and a distance of maybe 20 feet. LOL.
As long as I had the gear out I thought I'd double check the results for the Whole House 3.0. Yup. It's just as illegal as it was a couple weeks ago. More so, actually. I tested at 99.5 (I used 92.7 last time) another very dead spot on the dial. Readings were consistantly higher. I'm not figuring and typing them all out, but they were all higher. Which I guess makes sense as with the little antenna on this transmitter, the higher you go in frequency the closer the match for the small antenna.
I was still going over in my head how the two certified transmitters I tested were so far over the limit, and trying to figure out if there was some anomoly that would have made my tests inaccurate so I was itching to do it again. Same results.
So, FWIW, TYG.
