Information and modifications for the AMT3000 and AMT5000, SSTRAN TX's!
« on: October 14, 2025, 1619 UTC »
https://internetwork.com/radio/sstran.htm  I don't have an SSTRAN AM Part 15 transmitter, yet, but for those of you that do, here's a link, that was FWR'ed to me, of a lot of great INFO here. And, bonus INFO on AM modulation and testing as well.

The best two statements of advice that I've ever gotten are from my brother-in-law in the early 1990's. 1st one, when I bought a used '89 Olds Cutless, my bro-in-law said, "Congratulations!!! You've just bought a deficit!". The other, was on a work environment, " No matter where you go, it's going to be f***'ed -up!". No truer words have been spoken.

There's an SSStran AMT3000 on eBay for $399 OBO https://www.ebay.com/itm/389044025538

I'd probably snag it but I already have one and 2 Rangemasters to boot. I don't need another.

That AMT3000 and AMT5000 page was written by broadcast engineer Clark Burgard N1BCG and, as you say ThaDood, is full of great information. I think that the majority of folk who own SSTRAN transmitters bought them to broadcast to radios around the house, and are not inclined to go to a lot of time and effort to maximize the effectiveness of their installations. If it helps just one or two people though, it's worth it.

.. I think that the majority of folk who own SSTRAN transmitters bought them to broadcast to radios around the house, and are not inclined to go to a lot of time and effort to maximize the effectiveness of their installations. ...

I noticed the one on eBay is set for broadcast on 700, at first I thought that odd (I didn't even realize the AMT3000 could transmit that low of a frequency), but as you point out; antique radio collectors primary concern is not range.. so maybe that explains why such a low frequency was chosen by the previous owner of the xmtr on eBay. Maybe that was the actual intention, to limit the range and keep it in the room.
