So I’ve been searching for a plug-and-play FM transmitter for awhile now…
AHHH!!!!
I haven’t found anything good.
Does anybody know of a good FM trans. that goes about 700-800ft?

Planning to hook it up to my mixer.
Any help is greatly appreciated 😀

Only Transmitter I can think of that usually
goes that far is a Ramsey.A C Crane will do that with a modified antenna and that power adjust. But that would probably go out of FCC Specs for Part 15.
Total posts : 45366Yes you can. I believe the limit is 900ft.
Total posts : 45366There is a lot of info and discussion about range here.
Range is not the limiting criteria in this case. Under Part 15 license free operation in the FM bcb, the limitation is signal strength, which is 250uv/m at 3 meters from the antenna. For an average stereo receiver that translates to about 200 ft. clear. An FM signal drops off quickly, i.e., it’s either there or not.
If you use, say, a Decade MS-100 transmitter in mono mode (stereo pilot signal creates a power overhead that reduces range significantly) and receive with a very good late model auto radio, you might get as much as 700 feet according to some recent tests discussed here.
The best bcb operations for range come under Part 15 rules for AM radio. While AM is more vulnerable to interference, the range is much better, need not be line-of-site, and fades out over longer distances. In fact, good signal propagation in the AM band during daylight hours is dependent on having great ground conductivity, such as the tried-and-true buried ground radials, or in my case, the sea (my TX is on a cabin cruiser). Again, there is plenty of discussion here … just do a search on ground conductivity.
HTH …
Total posts : 45366That 200 foot thing is pretty darned close. In Total Range For my FM i get 1,000 Feet in some directions. However out of those 1,000 feet probably only 200 of them are crystal clear. If my station was in Mono and not Stereo I’m sure that range would be much better.
Total posts : 45366I’ve found that range in either AM or FM depends a lot on the receiver. Car radios do very well these days because the better ones have good dedicated digital filtering circuitry which seems to be missing in almost all home entertainment radio receivers.
Total posts : 45366If you can find a Panaxis ACC100 (mono version), that would do the trick. I just sold one one on e-bay. They’re FCC certified and sound pretty good (not nearly as good as the Decade, but then they’re a lot less expensive). A bit prone to hum, but I just replaced the stock wall wart and eliminated most of it.
