It is only to be used along with the service manual not as a replacement for it as it applies to the appliance type, not the specific model and will go into more details on repairing the appliance.

Then the bandspread is calibrated for just that one particular scale on the bandspread dial. I wanted an outside, random-wire antenna to compare with the loops so I threw some gage insulated wire over some tree branches and brought the end in through a window. But then I couldn't close the window. I also drove a ground rod right outside the window and used the same type of plastic-insulated wire to connect it.

Now that it's getting cold out, I wanted to be able to close and latch the window. Luckily I had picked up some scrap copper foil or sheet that looks like a ribbon about one inch wide and three feet long.

There were two pieces in the dumpster at the electrical contractor's building where I work. I didn't have a plan for it at the time, but it looked useful. Anyway, I cut two pieces of it about four inches long and soldered a short piece of wire to each end.

Then I laid the two strips across half of a piece of clear poly package sealing tape two inches wide and maybe a foot long. Folding the tape over in half on top of itself and the copper strips hold the strips together, parallel and about an inch apart.

It's a little like railroad track and ties, but only one wide plastic track and two copper ties. I can put this thin sandwich in the window and close it completely. I suppose now I'll have to find out what the copper came from so that I can tell other people what to look for or ask for. At this point, I have no idea.

But I do expect that it was part of packaging some large electrical device and might be commonly found in nearly any electrical contractor's scrap pile. I've also used my shielded loop antenna with the DX and it worked really well. Two recent magazine articles inspired me to improve my random long wire antenna that hangs in the trees outside the house. It's about the "EZ Hang" which is basically a Wrist Rocket slingshot with a fishing reel mounted on it. You shoot a weight with fishline tied onto it over the tree branch where you want your antenna to go and then use the fishline to pull up the antenna support rope.

In this one the author mounted a fishing reel on a home-made wooden slingshot. I combined the two and put a cheap Zebco reel from a garage sale onto my old Wrist Rocket slingshot and doubled the height of the wire thru the trees. Next I'm going to add another wire oriented 90 degrees from the original one, and much longer.

The mains hum can also be heard through the speaker at low volume. The unit can be modified to reduce the hum by adding additional filter capacitors across the supply rails. Adding uF will greatly reduce the background mains hum eminating from the AF amplifier output.

As soon as you hit 3 or 4 on the gain setting, the AGC kicks in. Slowly turning the gain up further causes no noticeable effect apart from the S-meter increasing, because the AGC is attenuating the increased RF. In this day and age s , the DX ghastly underperforms and is plagued by usability, stability and selectivity issues. The only reasons one should consider purchasing a DX would be:. The other option, if you are into the restoration hobby, is to purchase a DX in fair condition e.

It is usually the metal casing that deteriorates, with rust being the most common ailment. Electronic repairs are also easy because it uses discrete components on a single-sided PCB as are almost all other radios of that era.

Toggle navigation WebDevSys. Home Services. The selectable 'bands' are: 0. Performance Strong local broadcast MW stations don't appear to cause any major dramas or overloading of the DX's front end, although weak images of strong local stations can appear on the higher bands. Conclusion In this day and age s , the DX ghastly underperforms and is plagued by usability, stability and selectivity issues.

As a collectors item. Overall Rating: 6. Billy D. It consists on ly a fet, resitor and a capacitor. I have picked up two signal stregth points and is more sensitive. Re adjustment of the 3rd I.

Timothy , Wed, 08 Oct am: I would take a look at dipole antennas as they are easy to make and the calculations are not hard to do to get it right. I also want to say though that I am just studying for my ham test and I may be giving information that may not be the best.

Dewayne Dykes , Thu, 23 Jun am: An external antennae is required for reception. You can start with a simple wire can be insulated or not of at least 15 feet in length. Attach one end to the high Z connection on the back and stretch it around the rooom or out the window to yon tree. A better installation would be to attach a random length wire whatever fits from your house to the tree or post out back and bring it into the house using coax to sheild it from household interference.

Ground the sheild on the coax and use the center wire to attach to your antennae and the receiver. An internet search will turn up many designs for effective homebuilt short wave antennae. Connect it on back with an alligator clip so you can unhook it when not in use. Good luck and enjoy. This is one of the better Realistic shortwave radios, and performs well considering its price point.

I usually turn mine on an hour or more before I actually intend to use it. It requires a light touch on the bandspread control for SSB, especially for the higher bands. A good casual monitor radio. Audio is better than the DX series.

Selectivity surprisingly good for the price range. Don't buy it at any price if the dial mechanism is messed up unless you are a masochist. I plan to keep mine. Roy , Tue, 05 Mar am: Have you still got Dx ? I have a DX Does anyone do repairs or mods to these units?
