Another Legal Question

[W5JLF]

The problem I have is a desire to hear my new Pro-2096 at several different locations around my house and yard. Now for the question. What kind of legal issues will I generate if I feed my 2096 into a low power AM transmitter like the one sold by Antique Electronic Supply (http://www.tubesandmore.com/) item K-488. This would allow me to hear the 2096 at any location in the house, yard, garage or backyard workshop. All I would need is a standard AM radio. I will limit the output to a level that won’t go past my property line. A friend of mine restores antique radios and is using one of these connected to a multi disk CD changer, playing old 30’s & 40’s music, to transmit to his old radio collection around his house. Thanks.

Why not just use a LEGAL FM transmitter like the iRock???
They sell them at Rat(cell)Shack for $20 & they work great.
Much less spurious noise also from the wireing ect around your house.

Resale shops often have baby monitors for $5 or less. Might be just the ticket.

I've used the baby monitors, but the audio leaves alot to be desired. The Part 15 FM transmitters work much better.

What kind of range are you getting out of those cheapy Part 15 FM transmitters? One every one I've ever had or played with (both dial tuned and PLL), 30 feet would be exceptional.

Unless you're talking about something like one of these:

but then, you're walking the fine legality line.

The couple of times I've used them at home, I was only trying to send the audio 15-25 feet. Basically, from the scanners in the front room that are connected to the outside antennas to my garage or back bedroom, where the scanners are on indoor or rubber duck antennas. For what it's worth, using the Part 15 FM transmitter gave me much superior audio compared to the baby monitor method.

Some years back I picked up a device intended to transmit the audio from a Playstation so the players could use headphones and not disturb their parents. I used it at work to retransmit the audio from a scanner to the receiver on my belt when I was driving a forklift. That way I didn't have to plug and unplug my headphones everytime I got off and on the truck. It gave me a 40-60 feet range. I no longer drive a forklift, and don't know where I put the transmitter/receiver units, so I can't check the brand.

You can use one of the wireless stereo speaker units from RS or Circuit City, etc. Just get a mono to stereo adapter plug and you can have two speakers - one at the radio and one in another location. Get a second set and you can have four speaker locations and a spare transmitter. Speakers require AC power.

Ok here is a question. Since it seems these little fm transmitters cant transmit very far is there a way to up the ouput power on them? I mean they have all the electronics needed to tun now how can we pump up the power so to speak to get the most out of them. We would obvioulsy have to tread lightly on the FCC rules for that but as long as we dont go over the limit what can we do with these little guys.

And yes I have heard of the PCI max. I am a DJ using SAM3 so I have definatly heard of Pci Max.
