Just gathering information. Other than the C. Crane FM Transmitter 2 and the Whole House 3.0, what are current, commonly available, actually certified FM transmitters out there these days?
Don't give me legacy transmitters, or old favorites, or things that are not presently available as current stock.
Further testing to satisfy my own curiosity coming up this spring.

It might be interesting to test some of these iPod type transmitters powered by a battery
i did test ONE of those little battery transmitters last fall. It was a 2xAAA battery powered unit with the GE brand name on it. At 3 meters, 61 u/Vm. Extremely legal. LOL

Waio which is what i have is apparently no longer in production and you are directed to broadcast vision from the Waio.com website.
Tim, as we wait for people to suggest certified FM transmitters, I'll ask about your Ramsey plans, if you still have any.
Back during your test cycle you indicated that you might build and test a Ramsey FM kit.
The one I strongly recommend, if you pursue it, is the FM30B, an amazing kit.
Ramsey has dropped their kit line, but the transmitters are being sold at Amazon(dot)com right now for $150 (down from 199.0).
I have mine set at its lowest power level, which on a spectrum analyzer matches both of my C.Cranes, a Scosche FM4T and a Wholehouse 2.0. The Ramsey puts out signal for 200-feet at the lowest setting, and 1,000-feet at the highest setting.
Unikit has some Industry Canada RSS210 transmitters (which are identical to FCC Part 15) and I believe they are FCC certified as well.
Decade of course....There really aren't many certified other than the ones mentioned...CCrane, Wholehhouse, Decade, Broadcastvision....then those little bad little battery ones or the ones that are powered from your car(similar) which were just designed to get your music from your MP3 to your car radio...five feet away.

There's the ACC-100 by Progressive Concepts.....A forgotten one.

Mark, I scrolled around the website for the Cellcom Transmitter and can't find any mention of certification.
With a range of 300 to 3,000 feet it couldn't be 15.239 compliant.
that cellcom is not FCC certified for one very simple reason. i spotted it in the picture of the rear of unit, can anyone else spot the reason?
Looked closer and saw "meets part 15 rules" for the cellcom transmitter but that doesn't mean certified. But the wording when looking quick makes you think certified, I stand corrected.
Mark
There is a BNC connector for a remote antenna and that would make it non compliant in Canada and I'm not sure about the USA....also it says meets part 15 rules, not certified with a number.
I stand corrected on this one.
Also has no serial #?

Looked on Canakit site and no unikit transmitter mentions anything about being certified. Long time ago called them and asked about this and was told no and it would be to much trouble. Also a kit you build yourself can't be certified.
Mark
That's probaly true, I guess, that kits cannot be certified... I wonder why not?
Just from memory, I'm thinking that selling of pre-built transmitters is only legal if and when they are certified.
My own opinion is that kits are the so-called "home-made" transmitters, which is expressly allowed, but only five can be built.
I was sort of thinking as I wrote this, so I hope it ended up making sense.
The rules are right down there on the shelf but I don't have time to look things up right now.
