Hi glad to join the fourum had my DX394 for several years with no problems only usual querks but suddenly it has gone deaf the low-Z jack fails to absorb any...
Suspect the 20 Db Attenuator switch, slide switches of this type are notorious for going High Resistance, squirt some switch cleaner in to it! This switch only...
I shall give it a go when next in the shack.Hope it's not a smc component though a bit fiddly. Thanks John Earnshaw M0JFE Ride The Waves And Make New Friends ...
Without taking the covers off I can't give you a definite answer, but on the PCB layout it looks like a bog standard PCB mounted switch on the top of the main...
Hello John and greetings from the White Mtns of New Hampshire! Your 20db attenuator switch is either very dirty and needs some cleaning spray or it may be...
Many thanks for the information I have sprayed it with no luck I shall be next looking at either removal chack and fit new or by -pass it .Funny how it's only...

Looking at the Schematic the Low Z input is transformer fed to the input, The Hi Z is fed into the input on the secondary side of the input transformers. So a...
Many thanks for the reply .I tried it using a full size G5RV and a FC-107 ATU with NO signal input hence why I think a component might be down.I will look at...
If you have bypassed a potentially faulty pad switch without success, then it does sound like a failed component on the primary side of the transformers. Maybe...
LW, 150 to 509.9 kHz, MW, 510 to 1729.9 kHz, SW1, 1.73 to 4.4779 MHz, SW2, 4.478 to 11.5899 MHz, SW3, 11.59 to 29.9999 MHz. LW and MW use the Ferrite rod...
Hi John, Before suspecting the attenuator switch, which could very well be the problem, try disconnecting the shield of you Lo-Z antenna with the radio on and...
My DX 394 worked perfectly in my former house but in my new location the ultra-violet lamp in the water filter system causes much interference. I have covered...
George, try running the 394 on battery power if you can, as a test to see if the qrm is conducted (line) or radiated (RF) from the UV light. I'm guessing the...
I suspect it is a hum/buzz sound just like low energy light bulbs give off here in the UK.Like some one else suggested to check if it comes down the antenna...
George, Could shielding the inside of the 394 help? The casing is plastic and there is a modification in the files to help reduce outside interference. Good...
I to saw the article on that mod and seem to remember copper gause that we used to line the rear of the TV with.Can you still buy this product anymore in the...
Forgot to mention that my 394 is lined with metallic shielding and is not susceptable to interference from my cablebox received on my 160. mary and joseph...
Just to let you know I have the service manual but I shall have to email it direct as the server won't accept a file this size. I have done some tests and the...
... John, the service manual is already freely available from two other sites, linked from the group website's Links section. How big is you file? I would be...
John, I don't think I'm telling you anything you don't know but here goes: 1. I think you said that you get strong signals from the Hi-Z input but have...
Go here... Its the best site around for info on the 394. Course I MAY be SLIGHTLY prejudiced cuz....... Its my site!LOL! Even has a colored schematic. ... ...
Go WHERE? You missed to give the link:-)) ... ____________________________________________________________________________________ Boardwalk for $500? In 2007?...
Ok, gang... This is gonna be a bit weird... Anyone not interested in AM DXing should probably delete and move on now... First, I'm not crazy. I've been...
Hi Bill, It is not just your town as I hear it here in Fall River, MA on a daily and nightly basis. And, it is not just on the AM broadcast band. I have...
Bill: It was here in Shelton, very severe Thursday night. I wrote it off to the approaching storm front, but it returned Friday night, also heard down at the...
