Part 15 FM Transmitters

A certain indonesian seller on *bay sells an exact copy of the 1w exciter you are talking about.

Wonder if that's the exact same transmitter? The Broadcast Warehouse model is flat down to 1hz and is about the best exciter around as far as not adding overshoot to heavily processed audio. It's the model that the Breakaway Broadcast Processor folks suggest. Looking closer, I see that it say "BW" on it....it's very likely the real McCoy!
 
I contacted the seller and he told me it is exactly the same !
I wonder if the seller obtains them from the same source as BW ?

Over the years the pll+ has changed, the aussie seller has the early 4 bcd dialup version, then they did the 3 bcd switch version, then the newer looking version.
I still have several of these versions from over the years, they are an excellent exciter.

I remember the "flat to 1hz" quote, i have not seen that quote in recent years, iirc they are now saying flat to under 10hz ?

What is very important is to mount and enclose it properly, and supply a clean 15v supply to get the snr specs from it.
 
I took the covers off my TX4, I was wrong, the board seems a bit different than the 1w PLL+. Disconnected the fans, but the buzz is still there. The power supply looks like a fairly common oem type. At some point, I'll have to try a different one. The construction of the exciter and PA boards look top tier.

RadioEngnr... What frequencies does that transmitter offer?

Speaking of synched light displays, I saw a killer one in Manitowoc, WI over Christmas. First class job.

40 Channels make sure you look for that and not the 8 channel the 40 chanl covers 88 to 92
If your interested in a FM Transmitter that goes from 0.001watts to 5watts

I've seen his light show on-line, he's like me when it comes to synchronizing lights we like to make sure every element of the music gets triggered

Here's a video from mine, and if you watch the video the audio you are listening to is recorded right off my FM Radio app on my Android Phone with the headphone jack connected to my camcorder

Cannot make a comparison as the pll+ has changed look over the years, smd being an obvious one.
On the earlier versions you could buy the build it yourself kit version, the later smd versions you could not.

The old Broadcast Warehouse pirate transmitters are awesome. I have one from years ago. The one I have isn't the one with the processing and XLR connectors. I bet that one is even neater. Ahhh the good 'ol days of Broadcast Warehouse (BW Broadcast)! On the PC board silk screen, in the corner, there's a little picture of a hand with the middle finger extended. LOL! I guess they've come a long ways into the "legit" world from back then...

I miss those days. I also miss NRG Kits (nee Veronica), with which even BW couldn't compete in the price/performance category.
 
This thread made me remember in Jr High buying a Radio Shack FM transmitter kit that I had to build. The hardest part was doing the windings. I spend a few hours on that green wire to make sure none of them crossed another (you know, I had to follow the instructions). The thing ran off of a 9 volt battery which I wired in a 9 volt transformer. I took the short wire antennae and wired it into an old set of rabbit ears and put the rabbit ears on top of the chimney. With that little homemade Radio Shack kit I was able to have my little station heard eight houses down the street.

I am 50, so this was before computers. So, all of my broadcasting was live from my record player, 8-track player, portable cassette player, and cheap Radio Shack microphone. Ever tried to cue up an 8-track tape? :)
 
Re: Barry I dont remebeirng you as i was at WGHR a year

when I came on there the four bay ring and stud made by Celwave were going in four direction I set them to the south in a 5/8 wave spaced and did it get out went stright into Atl downtown well and it was going well till the presnt of Souther Tech got the roof of the admin build done and it all came down tower and all and they never appl for a chang of feq so they could saty on after 102.5 out of mabelton came on
 
I was the GM at WGHR when we signed the station on in 1980 until 1983. The antenna array was installed correctly in 1980 by the folks that erected the tower. Around 1982 or so, some of the electrical engineering folks (who were part of what was then a large engineering department) started messing with the array. They had done it before I could stop them. At that point the adviser was an EE professor and took the stance that it was good for them to experiment. My hands were tied.

Definitely hats off for the 8-track cueage. Cueing is an art.
 
well a small fm transmiter unit meant for automotive use would do well. you could use a longer three pin mini stereo cord and it uses that as a antenna so the better antenna the more of the home cover you could get.
