Hi AllI have a DX 440 with a broken display. The display has a discolered screen but if you look real hard you can still see the numbers indicating the...
Hello Rick and other users. I have a now classic ATS-803 with the Emerson label when you use the AM Button the radio tunes it's full coverage from 153 Khz to...
Hey Folks, I picked a really nice DX-440 on Ebay and just got it. My other, which I bought new back in the 90's was getting tired...I bought the one for 45...
Yes trash the wall wart get a really clean low amp power supply. One with good filtering. If it's a 12V supply build a 9V regulator circuit and install it in...
John, If you use a "linear" power supply, it will be a lot quieter than a switching supply. I am on the road, so I don't have access to my 440. What is the...
Bernie/Jerry Thanks for your suggestions...I plan to shop around and get a good lenear/regulated supply. Next I need to build a decent multi long wires...
Yes John, More wires are better than fewer. I have uploaded a pdf to the files section (The Radio Amateur's Handbook) which is an extract from a 1922 book...
John, I'll take a slightly different view. Sensitivity is seldom the limiting factor on modern receivers. There is plenty of signal to be had. The far...
I personally agree with Bernie here. For me the limiting factor on the DX-440 was 'band selectivity'. Once I put the simple MFJ-956 preselector between wire...

Good day. With permission from the moderators. I Radios receiver for sale, see pictures of it on: http://qsldobrasil.blogspot.com.br/p/radios-vendas.html ...
Hi John, In my view, you only need more than one wire if you're really emphasising one SW or ham band over the others, or you're transmitting, where SWR can be...
Hi Lawrence, Thanks for your info and the upload...great and interesting information. I will review this over the weekend and work on my antenna. I also want...
Saturday I made/put up a 100' dipole arial...and picking up good signals.LW SW SSB, etc. Now I playing around with some WeatherFax software. See photos in HF...
I inherited an ATS-803A from my dad in '97; only now really trying to get it to do something. I have the AC adapt; all batteries are installed. The wire...
. . . just added a short item from K.E. Edwards: "Radios that Work for Free", Hope and Allen, Grants Pass, Oregon, 1977. This shows how to make an easy...
In AM, turn the BFO switch Off. IN SWin the evening, Do expect to pick up Radio Havana for example, at 6000 khz and 6060 and others. You should indeed expect...
HI, My 803a performs exceptionally well but the upper range MW performance is lacking. For example 1650am is lousy reception. I understand the radio does...
Hello, I thought the loopstick did work on the 1600's. (I could be wrong). If so then possibly the coil on the rod could be readjusted to give less inductance,...
Hi Larry ... It's been a while since I last tuned in LW on my 803. I know we're a bit out of season now here in the US, but if you remember, please post here...
Hello again Matt, I too am out of the season for longwave. Unfortunately. Its just too futile for me right now. The main reason is because of a rooftop...
I have the same "problem" on my DX-440. To avoid overloading on 160M the bandpass/highpass filter kicks in above 1620 KHz. They were built before the MW...
Hi Rick, The main problem I have seen with my set, is the non-soldered connectors used in the radio. One typical problem is the power connection which is done...
Anybody know where I can get a suitable replacement strap for my radio? Also, still having issues with reception, based partly on the performance of an old...
Hi Folks, I have a question not related to this group but need some advice. I have a SSB transciever that requires according to the spec 12 vdc 30 amps. I want...
I thinks it's time to bite the bullet and buy another on Ebay...that's what I did after realizing my orginal DX-440 was just not getting it. Or send your radio...
I would go with a good Samlex 1235M I use them on all my HF Gear. I believe the price is in the $35 range. A good shortwave receiver like the 803A can many...
