The Landmark transmitter I have has both an FCC Part 15 certification number and an Industry Canada RSS210 certification number. I had looked it up in the Canadian database, and it was certified in Canada with U.S. field strength numbers (which makes sense, given the relatively small market up here). It does have the F connector with the dipole antenna, just as the certified Talking House has an F connector allowing you to connect to an ATU. Obviously, including a standard antenna connector on a certified piece of equipment isn’t always forbidden.
Landmark made a number of transmitters in the day. And a lot of them had nearly identical product numbers, causing a lot of confusion. I can’t speak to anything Rich or anyone else said in that link, but the one I have is definitely Part 15/RSS210 certified (with the official stickers on the case) and therefore legal.
The Landmark doesn’t have the greater field strength of the Canadian-tuned Decade MS-100, but the configuration allows me to install that (unmodified, factory supplied) wire dipole antenna outside at the top of my house a lot easier than the Decade (which was meant to be installed indoors) – and it gets almost equal range compared to the Decade sitting on my desk (which has to penetrate walls and other obstructions closer to the ground). I certainly don’t get the maximum 1 km range from the Decade here in Pitt Meadows that I got on Bowen Island, but then, I’m in a relatively flat residential area, as opposed to being high on a hillside overlooking my desired coverage area, with almost nothing between the transmitter antenna and the receiving antennas of the cars in the ferry lineup.
As to why they stopped making it, who knows? I don’t think there’s a huge market for legal Part 15/RSS210 FM transmitters, due to the very limited range. A lot of manufacturers have come and gone in that arena. While Part 15 AM is challenging, at least you can get out a little further.
