Of the Top Two Certified AM Transmitters There is a Lesser Known 3rd ChoiceThey all talk about the Procaster and the Rangemaster but there is also the Grain Industries Certified AM Transmitter. No one has one no one has reviewed one so maybe this is the best of the bunch, we won't know until we find out. Visit Wayne Miller and AssociatesPlease indicate within 5-workless days whether you intend to review one of these. If not I will order one and give it the one two.

I looked at the FCC Data and some things jumped out at me: Audio Response 300-3000 Hz Power: Manual says 100 mW. Test data says 91 mW Modulation: 95% Lot of money when for a few bucks more go Procaster or Rangemaster Test Report: fccid.io/WLX-GI100A1000/Test-Report/Test-Report-1047231 |

Ew!
DHR scouts the idea: "Looked at the FCC Data and some things jumped out."
Oooo. Those things jump way out.
Maybe my big offer is with-held.
No reason to say any more about it.
Yet I wonder if there's something else. But what else would it be?
I hate to throw transmitters under buses.

That's unusually narrow frequency response for any Part-15 transmitter, more like something a CB or ham transceiver would have, and my guess is the designer intends the transmitter for the "voice" radio market only? It doesn't specify how strong the rolloff is though, so maybe an equalizer could help.
It's interesting, small and using surface mount, so the design is reasonably new.

Hobbybroadcaster kept threatening to review this transmitter. I can't seem to find one. Does anyone know if they ever did?

I Looked
Earlier this evening I stopped by HB and saw no review of this "Grain" Transmitter.
Looks like we've taken the lead for the moment.

Maybe the ALPB could get a review unit to use for a couple of weeks of evaluation, then put the review linked on the ALPB tech website.
In addition to how it works, I also wonder what's behind the name Grain Industries, and what purpose the transmitter might be targeted for. How is it used by its audience? I haven't seen it promoted much around Part-15 areas.

Carl, many months ago in a private email you turned me on to this one. I looked over their site but not seeing any mention anywhere else I went with the Procaster. I would love to see someone review this. |

I wonder if Grain Industries has a different market than we're aware of? They went to the trouble to have a unit designed and pro circuit boards made, along with written documentation on the unit, so they're into the whole idea of Part-15 AM for some reason. A larger granule of truthI went looking at the site again, and found this FAQ that talks more about the audio response. 300-3000 hz is verified minimum response, but actual response is much wider. waynemillerassociates.com/GI/faq%20operation.pdfBoomer |

The voice range is minimum response, but overall response is a respectable 40 hz to 12 khz at the 3 db down points. The bass region has slightly higher distortion due to the action of the automatic modulation control, that's the way I read it.
It would be better to have a one page spec sheet with numbers for comparison with other transmitters, but points to the company for keeping the descriptions plain and simple, no marketing language or hype, that's refreshing.

I have to wonder how many of these things have been sold.
You can find both Rangemasters and Procasters on the used market. The former a bit more frequently. But I've yet to see a Grain.
Personally, I don't see a compelling reason to purchase one. It's expensive, and doesn't appear to have any features over and above the other two.
If it was 1/2 the price, with maybe 3/4 of the features, then maybe.
