Greetings To All From Somewhere High In The Appalachian Mountains !
For anyone seeking an excellent quality, rock solid 5 watt FM Stereo Broadcast Transmitter you simply cannot beat this unit for a mere $35.49 plus $5.00 shipping from Hong Kong ! It delivers a rock solid 5 watts output and is VERY well built and uses an aluminum case enclosure, very robust for an excellent price ! This is great to have, even as a backup transmitter for the sake of a small investment, probably the cheapest FM Stereo broadcast transmitter you are ever likely to find !!

First forum post and glad to find the resource. Quick question for anyone... I notice the product link, as many made in china product, is a 50us pre-emphasis xmtr. Do you find this to be a concern with the North America 75us standard for de-emphasis? No biggie? Addressed with EQ?
I ask as for the last 4 years I've been using an EDM-CS xmtr which came preset for the North America standard, and I'm considering a bit more powerful unit. Thanks, anyone, for the knowledgeable reply.

Good Morning Dave !
I have found through trial and error that in fact, from my observations, that the 50 us pre-emphasis of this small transmitter and other Chinese made transmitters isn't really all that important. I use a a Xenyx Model 1002FX Mixer/Effects Processor and use it to tailor the sound of my audio before sending it out to my compressor/limiter. I also have a HPA (80 Watts) being driven by another Chinese made transmitter Model ST-15B, 5/15 Watts. Realistically, I have two of this model and neither one produces 15 watts, I get a maximum of 10 watts using a Bird Model 43 Wattmeter and 50 watt slug into a 50 Ohm dummy load. The station sounds at least as good as most of the commercial broadcasters and even better than some ! What make and model of transmitter were you thinking of purchasing ?

Hi Dave !
Read here regarding Pre-emphasis 50 us vs, 75 us... It isn't all that important really unless you are a 'type A purist'.. LOL !! Hope this puts the issue to rest for you.. Take care brother ! Let me know what transmitter you happen to purchase or are thinking of purchasing.

Thanks for posting the link. Yeah, maybe I am that 'type A purist'. 30 years of commercial FM broadcasting filled with dissatisfaction of signal quality ... for the 4 years or so I've used the EDM-CS I've been using SAM Broadcaster software and over the years have modified my compression/EQ processing to work in concert together and I'm quite pleased with the quality of sound; I wouldn't want to start messing with what took me a long time to develop.
I began using the EDM with a home-brew dipole enclosed in pvc and mounted outside to my chimney. It's worked well. Just bought a 1/4 wave ground plane and it works a bit better. Nice hole at 92.3 in my area and I'd like to bump up my reach a bit. The xmtr link you posted shows a mini plug to get audio in... the EDM uses L/R rca connectors and I'd like to stick with that although honestly don't know if that's a concern or not. Not sure yet of the new xmtr direction to take.
