Anyone heard of, or tried out one of these yet?

I think Larry W8ER had one of these a few years ago.

They are popular with real estate agents for drive-by narratives of houses for sale.

Well, if you read down the page... he claims to be able to put these on ham frequencies...
Mentions 160, 80, 40, and 10 meters (maybe 20 m too.)
But says "maybe not all at once..."

So, not sure whether they've actually done it yet...
I may email for more info out of curiosity.

Also claims 10 watts carrier.....

And for "export only, unless you sign an export agreement"

Under current Part 97 rules for hams, they're probably not legal for ham band use either.

I'm confused: I thought transmitter compliance was each ham's responsibility. What would make them illegal?

I think it's the fact they're being manufactured for sale to others.  If you yourself were making it, then yes, it would only be your responsibility for conformance to FCC regs with regards to spectral purity.  When somebody else makes it for sale to others, then they also have a responsisbility to ensure that it meets spectral purity regs under normal operating conditions.  They also have to provide proof (which costs money) that it does meet the regs for spectral purity.

I still have it Paul. Nice unit! Actually, I am thinking about putting it back on the air. The one I have is an 80/40 meter unit and it does put out 10 watts of carrier but that's about it. The audio is excellent. I used it to drive an AL-80B and got about 85 watts of carrier with it. Right now I am very busy playing with the K7DYY Senior and there's not a lot of incentive to dig the old AMMaxII off of it's shelf.

Marko, of PCS electronics is working on an AMMaxIII now but it is not available yet and I think he has depleted his stock of AMMaxII's.

That's it, you can build it yourself as a ham and no type acceptance is required but a manufacturer is still required to submit to type acceptance for sales.

So... Is  the K7DYY Sr.  "type accepted"??

Quite pricey at 1/2 large for 10 watts, maybe 5 watts in your car.
