Not olny trying, but using it, I've recorded about a month of weekly half hour shows with it already.
That's right, I didn't think about it for portable operations, you could bring just a microphone and a laptop and it could be the complete driver to the transmitter!
You could have file player, VU meter, compressor, audio filter all on the laptop, good idea. Pot your microphone up, talk over the music, do production, it's all there.
It could be good for a low volt transmitter at a car show, to play oldies and have an announce system without extra wires.
