131 owns an HF transmitter that dave built and I do not. It is a wideband linear modulated transmitter that does not have a receiver. It does not require a PC or CB radio to function. That's about all the info you will find on this product unless 131 will give some specifics to you after you said you didn't care.
Yeah I know 131 has one and was waiting for him to chime in. As for my comment about not caring to know anything about it I meant as a personal interest. It does not interest me in the slightest to own one however from a technical standpoint I have some interest in what it is in general as opposed to how it functions specifically. Some folks call motor mouth maul's modulator or the hifi stuff ghetto way driver stuff transmitters while others call a big amplifier a transmitter neither of which is accurate hence my quest to find out a bit more about this Dave Made contraption. In short it appeals to my tech interest but not my ownership interest.
