Hi Folks !!!! :-)
This is about the above "Part 15" FM car/truck hands free Calling... whatever... Model SBT1100 by "Sylvania' (really Osram of China)
Got this from Wally-world at around $ 15 bucks so don't expect much :-)
Well... it is FM and it is stereo and it does what it says but...
First off <heh> I looked for the FCC logo... not there... No mention to Part 15 in the 'instruction book' such as it is... The only mention to Part 15 is in micro-print on the bottom of the box... hmmmm... no FCC logo tho... but who cares right ?
It states it will broadcast 'up to 5 meters'... ok, it does that with a very strong signal... hmmm... no antenna... how be thou ? 5 meters is equal to, kinda sorta, 16.4042 feet... hmmm... this gadget must be coupling to the house wiring... It's more than that from the corner of the kitchen to this room... but never mind. It has a very strong signal so it must be coupling to the house wiring... right

?
Anyway <heh>, It's made for car/truck use and not in-house use so that might be my problem. It is being powered by the 'boost battery' that I use for the truck to get that beast working. But remember my battery charger makes a ton of noise and I have placed a bunch of ferrite 'beads' in/out everything to keep the noise down to the SDR and the Yaesu rig... the noise is suppressed quite a bit now for the SDR & Yaesu... but maybe the beads don't stop the out going stuff... What do I know... right

To be honest it's too damned cold for this old buzzard to go outside to check the field strength of this little beastie so I will take the 'Sylvania' aka Osram of China, at their word that this ((POS)) is within the legal parts of Part 15... And understand, I use this only to make my Honey Angel happy so she can hear Xmas music free and clear of the Ads and other BS that commercial radio seem to find the need to dump on us during this wonderful time of PEACE and whatever...
Yes I could run speaker wires and such all over the place in the apartment but messy is not my thing out-side of the 'radio room' and she might look at me 'funny' if I were to do so... but she is very understanding... if it doesn't involve wires hanging here or there !!!!...
Oh yeah!!! This Part 15 thingie, if Bluetooth'ed to your 'smart' (read that as 'stupid') phone will broadcast your phone conversations on the standard FM radio band... Not something I would want and if I know you folks... not your place to be in reality... Some of us are paranoid enough without broadcasting our caca doodee poo poo on the 'public' airways... Think about it !!!
And if people crab about the signal being weak... hell, I'll power up the CZE-07 (China POS) so the whole damned County can hear it !!!! I would if I had one that is... because I don't... never did... thought about it tho... not for Xmas music... I wanted to turn the area on-to DEVO... But that is another situation :-)
Have a happy to all you folks on this... whatever it is... And great DX to all !!!!!
73 to all from somebody else not me :-)
