There's more than one version of this kit . One is for transmitting inside your home and another that has a few different internal parts for longer distance transmitting .
I watched this cause it was interesting, but I am absolutely clueless what any of this means , what is this thing ? Do you run it between the radio and antenna ? Or is this what you hook to a mobile antenna and do 88 mph , push a button and time warp ? You could tell me it goes on the ISS for GPS and I'd believe it . So I'm curious , what is it/what does it do ?
Glad you found it interesting. It's an AM radio transmitter. I did a technical evaluation of it since many radio enthusiasts have this kind of transmitter. There is an interest in very low power AM broadcast radio stations that are unlicensed hobby broadcasters and are regulated under the guidelines of the Part 15 FCC rules.
With the way the output circuit is designed in this transmitter, there's really not any good way to increase the output power. However, connecting an RF linear amplifier will increase the power to whatever power you want. I am working on such an amplifier which I will post when I get it done. As for the antenna on 1700 khz, an "inverted L" long wire antenna is good, if you have the space for it. How much power do you want ?
@@alexalex-qi2ho You will be surprised at the coverage you get with just .1 watt. If you follow SSTRAN instructions for a base loaded antenna you could get a little over 2 miles. If you're gonna push WATTS into the antenna; then you might get a nasty visit from your Radio regulator.

Correct. This does have plans for operating it on an outdoor antenna as well, but the later version is more advanced circuit which is more efficient.
The AMT5000 has some upgrades to the audio. No power increase...it has to be PART 15. 100 mw.

Hello bob,i just wonder if we can increase the watts in this transmitter,how can i build an am exterior antenna for 1700 khz? Thanks from Nicaragua

@@bob4analog first i would like to know about costs, first for sstran and for the amplifier the power could be 50 to 100 watts..thanks and good day
