I guess I didn't see the part where he asked about FM signals. My bad. I thought the question was ... How far into space can Earth's radio signal be detected? Has any one checked from the Moon?
I guess I was paying too much attention back in basic electronics when the defined the Radio Spectrum. I always thought AM, FM, UHF, VHF, TV, Microwave were "bands" in the spectrum. From now on I'll have to assume "FM" when anyone asks a question about "Radio"?
Perhaps the question should have been ....Could I listen to 101.3FM next time I visit the Lunar Hilton?
If he had then I wouldn't have bothered to answer because frankly I wouldn't have known for sure. But of course that wasn't the question. And gee if I'd known that website sent him here then I wouldn't have bothered to answer since I'm not an "expert". See ... I thought the question was ...How far into space can Earth's radio signals be detected? Has any one checked from the Moon?
and not ...Hey ... Circuits Age dot com sent me here to find an expert on radio transmission and I just would like to know if Jethro Tull was playing on 650AM (assuming they're transmitting at 100,000 Watts) if I'd be able to get that on my transistor radio if I were standing on top of a mountain on the moon?
Getting the difference now between a specific question directed at experts and a generally poorly formed question that had no forethought? That's why I answered and why I answered the way I did. But thanks for coming in and figuring out that it really was a question about FM Radio.
I can certainly understand your point of view. I perceived the question as yourself has. If i had to dissect his question then, it would pretty much come to fruition of Woulf's logic. Either way, your answers and Woulf's are worthy.

I did a search of uaabloog, looks more like b.s. bloog. Also, looked at Jane's Space Technology but couldn't find Phased Locked Loop. Seems that info is either too shallow or too technical.
