Title: Icom 756 PRO3 on AM Post by: k6hsg on January 30, 2012, 04:45:04 PM Anyone used the 756 PRO3 on AM?
Is it good, bad or indifferent? Thanks John Title: Re: Icom 756 PRO3 on AM Post by: ke7trp on January 30, 2012, 06:05:07 PM In stock form they are horrible. You can build the ALC box that is outline here on this forum as a start. This is a box that plugs into the back of the ALC jack on the icom and will allow you to achieve 100% modulation without the radio pulling back. Once that is done, They start work decent on AM. You can then add in a good mic with a small outboard preamp and get the sound even better. In the end, You will be stuck at 5 to 6 KC wide on AM so they will never be HIFI unless that is dealt with. However, I know of several with outboard audio and the ALC box that sound damn fine. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
I use mine on AM only when something is else is broken and I have the ALC box. C |
