******UPDATE****** Got the squeal down to a bare minimum but was still experiencing a very slight squeal internally with carrier and audio all the way down. I could just barely hear it and could see it on my scope. After struggling to eliminate it I almost gave up. Then I decided to move things arou...

Thanks Dave457. Going thru the ACC2 port now and get very good audio reports although I haven't tried the c135 mod yet.

I think I'll look into an SDR solution for sampling audio. Probably the best and most non invasive way to go. If it's sampling my signal, or actually receiving it, isn't there a chance of front end overload due to close proximity of my antenna, or does it have built in attenuation? We'll either way ...

Thanks for all the info Bill.... You ROCK. I don't care what your wife says..... I think you're all right....lol. With the research I've done on the iF Filters, it looks like the only down side of changing them is a much wider receive than you may actually want or like. I think for the time being I ...

Hi Bill, I see what you mean about the different potentials. I have no AC hum at all right now. I found out the RFI leak I had was coming from a watt meter I had in line that was too close to the 440. I eliminated that meter (it was very old), and I completely lost the squeal I was hearing when tran...

Hi Carlos, A great place to start would be to read NU9N's site on essb and hifi radio. If you google his call sign his site should show up on your search. Read the page in its entirety and it will give you some great direction and give you an idea of the order you should have your components in. Goo...

*******UPDATE******** Yesterday I wired the ACC2 connector and tried that out. No more problem with the internal squeal. I believe the problem was a "gain" problem going thru the front mic jack. Since the front mic uses a built in preamp stage I think there was too much gain no matter what I tried. ...

Hi Bill, I am currently connecting the outboard audio input to the front panel mic. I plan to use the ACC2 connector in the near future. Everything is grounded to the radio and the radio is grounded to a grounding rod outside. I am currently using an Astron 20 amp power supply. All the rack equipmen...

Major RFI/Grounding Problem

Hi. I seem to be having a problem with either RFI or grounding with my TS 440. For matters of simplicity I'm only using my Ultragain Pro 2200. I will eventually be hooking complete rack to ACC2. I thought I'd start with the front mic to get an idea of how it sounds in general. When I turn up the mic...

Thanks for all the great input Bill, it's greatly appreciated. I really love this rig and would like to give it that deep "Kenwood" sound . Il take a look at the circuit and see what I can find there.

Take care,

ACC2 on my TS440

I just recently picked up a mint TS 440. I would like to run my rack gear through the ACC2 rear jack. I know the 440 is probably not the best rig to do this on but I'm wondering if it will still give improved audio quality. I realize that I'm limited to the IF Filter as far as bandwidth along with s...
