Being new to this medium, I am enjoying everything but one part, where do we find an antenna tuner unit for low power AM broadcasting ? Most call these auto antenna tuners but so far I've not found one. Can anyone give links to who sells them ? The main reason I want one is to help send a better enhanced sound (the manufacturer said I should use one) on my transmitter. It's suppose to mount between your antenna and transmitter, then you dial the clarified signal. I'm using a fiberglass antenna so I know the range isn't going to be much better but if the sound comes thru better it's worth it to me.
Is that exciter made by Ramsey Electronics. Hard to tell from the picture. I don't find it on their website.
The Fox Exciter is 0-20 W with 80 W P.E.P found on ebay
I wonder if you can make that transmitter comply with Part 15 rules, i.e., 100 mw input to the final stage? Although I have no idea where this transmitter is (will be) being used.
I would imagine that if you could, you could use the IAM Talking House ATU.
The one on Ebay, though very similar, is slightly different.
What I saw in the pix on the Part15 post that looked like a Ramsey logo between the buttons in the middle must just be designating the function when the button is depressed.
The frequency controls in the middle are different.
Also, on the left side one shows "RF & Electronics" and the other "Digital Exciter".
Why is this being rehashed again?
No, that is NOT a Part 15 AM transmitter, and NO it cannot be modified to be compliant with Part 15 unless you yank out the entire IPA and PA sections, and even then there is no guarantee the front end would hit 100mW to it's final without modifying that.
So..what is the point in spending several hundred bucks on that to end up chopping it to bits when you can find Part 15 compliant AND Part 15 certified transmitters on the market???
That unit could be used for a CC setup, but then again the OP is asking about the use of an ATU..which ATU's are not applicable or usable for a CC system..none have ever been made.
A CC system doesn't need it..not when the correct coupler is used like a TCU or CP.
And don't dare fire that TX up into a TH ATU..will most likely go into saturation at 1 watt, and most likely arc and fry beyond that power level.
