Hi all,
New to AM fone, so this is my first post. I'd like to improve the TX audio bandwidth on my 940. I'm getting reports of great modulation, but vastly reduced treble response - perhaps this is characteristic of the xtal filter on AM mode. One recommendation was to process my microphonium audio outboard with, say, a dBx 286 or a multi-band EQ, and try to "push through" the tight bandwidth of the filter. I reviewed Don KE1IZ's audio modifcation page here -
http://www.amwindow.org/tech/htm/ts940s.htm - and got to thinking. If I were to install a switching TS jack and 1:1 audio transformer at the point he recommends, I could use external processing with a connected mic, and be able to use the rig in its stock configuration with the jack disconnected. I've also heard audio can be injected at the back into one of the phone patch RCA connectors - which means I wouldn't have to drill any holes. Thoughts of how I should go about this? Open to suggestions. I have a few pieces of AF processing gear in the arsenal.
Thanks!
