FOUND ON EBAY

New Product, reconditioned, input and output connector "N", power required for working at 98 mhz 4w; In the PRAIS aluminum container it has been put a hybrid with a transistors mos fet SD2932 and a switching 12.5 power supply working from 80 to 260V 50/60 Hz; the procedure used for supply will let you to save more than the half compared to the old transistors and valves. Moreover the mos fet transistor generates a lot of harmonics bands extremely lower than the old systems and his life is much longer than normal components; The Case and the protections are PRAIS and intervene if there are anomalies plants (ross), short circuits or overload; This machine is controlled by a logical circuit which provides the perfect functioning of all its parts; Attention please! The SD2932 It's a power fet to work from 70 to 190 Mhz; it's 300w broad band; so to central band the gain is very good and the sd2932 work to 500w. The machine is testet on 500W but now is set on 450W and was tested for a long time. Its commercial value approximately corresponds to 3000 €. Good auction to everybody!

Gotta love flea-bay....... ;D
 
Wow, a 450 watt transmitter on eBay! Pretty serious power for a pirate. I'm sure someone can get an RF burn from touching the antenna with 450 watts. If it's designed as poorly as the seller's English, it'll spew spurs all over 70-190 mHz.

Heck, you can buy commercial transmitters from e-bay. Nowhere does anything say you need a license. FCC may have a differing view however........

I'd love to see a spectrum analyzer pic of that thing.
 
Ive seen a bunch of FM transmitters usually being sold from China that are likely outside part 15 requirements. Many of these cover international FM bands so they can broadcast anywhere from 76 to 108 mhz. Makes you wonder if pirates are using these below 88 mhz where they wouldn't get noticed since VHF-L is mostly empty after analog shut down.
 
If this rig were AM, it would make an HD AM signal look clean. On FM, count the harmonics and the spread spectrum. Gentlemen, Start Your Spectrum Analyzer. Time to hunt the Fox.

There was a powerful pirate station with 5000 watts on 87.7 in Boston.

I seriously doubt it, as there probably aren't more than 5 listeners with a receiver to tune that band. At least not around North America anyway.
