Where can I get a good, unbiased review of FCC certified AM transmitters (not kits)? I know of four of them:
RangeMaster 1000 www.am1000rangemaster.com

Ultra Sensors Inc (FCC ID: DPD624TA100)
I’m not sure if the Ultra Sensors transmitter is still available, but I read a very good review of it several years ago. For the others, most of what is available is from the manufacturers’ websites. I would consider comparative user reviews a much better guage.
Do a search on Part 15.us

Part 15 transmitter reviews

The GI-100/1000 has terrible audio response, as listed in there specifications pdf. 300 – 3000 Hz
GI-100 audio response
Is that the actual response based on your tests, or is it the minimum guaranteed specifications from the manufacturer?
GI-100 audio response
As I stated above “as listed in there specifications pdf” so it’s the manufacturers specifications. http://www.google.com/url?sa=t&source=web&ct=res&cd=1&url=http%3A%2F%2Fwww.waynemillerassociates.com%2FGI%2FAM_transmitter_manual.pdf&ei=mU4hSqUdkbozyumpoQk&usg=AFQjCNFoIdbxo1DFP25ZiN-bqLpJURGGYA&sig2=-kzr1aS3z3HpTyRi40Qk1A
Part 15 transmitter reviews
I tried to give more information yesterday and today, but someone set the spam filter too high on submissions and every time I go into detail and provide links, the system blocks my post. After researching and reading all the reviews I could find for the procaster and the rangeline, I decided to go with the procaster. As for the GI-100/1000, if you look at the Operators Manual at the domain name you provided, you’ll see that the audio response makes it unusable.

Send me an email about that and I look into it. I haven’t encountered that before. [email protected]
GI-100 audio information
According to the FAQ page on the GI-100 website, data taken on the unit indicates that the audio bandwidth is much wider than the specification would indicate. The data is presented on http://www.waynemillerassociates.com/GI/faq%20operation.pdf
