I just joined the group and am hoping to help. I was reading the mods list. What caught my eye was the DSP to do list. I am no electronics wiz but it gave me a...

Hi all, I have had my dx394 for about 4 years now and have been quite happy with it, but with just 1 or 2 little niggles (like the chuff chuff sound), then...

I have been using my 394 /model A, unmodified, to listen to cw on 40 meters. I have a 50' wire antenna wrapped around the house, not a significant signal...
John Your symptoms are typical of the IF bandwidth being too wide for the mode you're trying to listen to. What happens is the radio's automatic gain control...
... Another classical technique that I learned with my first SW/Ham radio (a Heathkit AR-3 43 years ago) is to reduce the RF gain and increase the Volume in...

Yeah, I know Tom....you and I have spoken about this before. I'll check that link. I'm in Cincinnati,Ohio. My 398 gets sent back to me tomorrow from Cal....
Chuck, Trust me when I tell you that you *can not go wrong* with the antenna you just stated (A/D Sloper) that is what I have used (along with three others)...
Tom, I just checked that 'link' and 'tried' to figure it out...lol. I didn't see anything or anyone that is modding those. I thought with this being *The...

Thank you both, Al and Tom. I would not have guessed the bandpass could be as broad as 10 Kc or more. I appreciate your directions. As it is, turning down the...

I have a plug connected to an antenna outside but I'm not sure the radio is taking the signal from this or the telescopic antenna. I don't have a manual or...
