AM bandwidth is directly proportional to the audio roll off settings of the audio process. Standard Asymod on board filter roll off ~10 kHz, expandable to 20 kHz.
Hi does anyone know if you can plug the PTT line on an AL 811H into the relay socket on an Icom IC 7300, to start with i didn't think you could, but i have just measured the voltage at the socket on the radio, the one marked relay next to the ALC socket and it reads 00 on tx and rx, so i think it grounds out as you would expect it to, but there is a lot of hoo hah about 16v at 0.5 amps etc, in my opinion as the amp uses 100 mA at 12 volts at the PTT i think you can plug it straight in the socket, but i'm not brave enough to try it lol from Fred g4vvq in Uk.
What is the bandwidth of the modified AM modulation?
AM bandwidth is directly proportional to the audio roll off settings of the audio process. Standard Asymod on board filter roll off ~10 kHz, expandable to 20 kHz.
User adjustable from 3kHz to 20 kHz.
Asymod rolls off at 10 kHz, expandable to 24 kHz and beyond. Roll off points have to be set via audio processing gear as narrow as needed .

Nice
Does this open ssb from 10hz-beyond 3k?
TX Max BW = ~4.2kHz
How much would that be if I sent you my 7300

Thank you.
Yeah! Did you get this done??? I have mine in the box unopened ready to ship out.
