I remember the 49 Mza intercoms. They did use the power lines and they were really good at transmitting an entire neighorhood or school campus especially wnen they had their own power transmirmer usually at the beginning of the campus. I was able to transmit from North Wing 3 all the way to the AB cottage at Michigan School For The Blind. Pretty nifty I thougnt. We would talk after school up till bedtime at times. If I wanted to get ahold of my friend Wally I’d call him. We tried to get 49 Mhz Realistic intercoms on the same frequency so we could talk back and forth. It was awesome.
Playing around with FM Transmitters as a kid I never tried the power line trick but I do remember connecting one to a police scanner and getting out 2-3 miles. And I got a hold of a FM Stereo antenna (beam) and I even got out to the Grand Ledge High School wich was west of me. Being 3 miles from the airport I didn’t want to transmit east of my house. This was backi on 79.
Yes I think more work needs to be done experimenting with carrier current FM. Someone who knows how to wire up that kind of stuff but I really don’t see why it would not work if tuned right. Especially around 88.1 to 96 Mhz as its closer to 49 Mhz where it worked for the intercoms.
Now they sold for a short time AM Wireless Intercoms that transmitter just around 1700 Mhz. The first cordless phones (Before the 46-49 Mhz pair was there. I didn’t play around with those too much but I do also remember the wireless phone hacks that used the 46-49 Mhz and there were a few that used the old 1700 Mhz band and they even had a high quality audio where you could use them for dial up computer connections (remember those)?
I know the FCC reads these forums you can bet that and I’m also sure we could get a lot done. Doesn’t matter how much the corporations want to bribe officials their is starting to be public support for personal micro broadcast stations. So they can only fight so long and I do know from what I’ve learned in Radio there is a PICN rule. I don’t know if the FCC has enforced it in years, but nevertheless its there and one who has the right lawyer could argue that if Johnny Smith’s one mile or 1/4 mile station is hurting you than your not following the PICN and YOU the licensed broadcaster need to either follow it or take a hike.
