My DX-200 is a drifter. Pretty worthless with tinny sound.
It does "look" cool though.... "Frank Dresser" wrote in message ... "GO BEARCATS" wrote in message ... You have one of those Frank? You like? LOL. I love mine. I had two and traded with DXZoner, who used to post in here about a year ago. I've got mixed feelings about it. The sensitivity and selectitivity are OK. The radio rejects power line noise well. It doesn't use much power, and it looks like it would be easy to make an external battery pack for it if I wanted to go portable with it. The image rejection is poor, especially on the top two bands. The stability is OK for AM.. None of the problems are unexpected on an unexpensive radio. In my opinion, the radio's real drawback is it's tuning. The tuning has too much drag and backlash. It feels rubbery. The dial graduations are too coarse. The fine tuning isn't nearly as useful as a real bandspread. I've only seen pictures of the DX-200. It does have a sort of family resembelance to the DX-100. The DX-200 looks to have better dial graduations and a real bandspread. If the 200 is the 100 with better tuning, it's probably a pretty good radio. The DX-100 is a decent radio for AM DXing. I can often hear WLW during the day here in the Chicago area off the internal ferrite antenna. The radio's weaknesses get more troublesome on the higher bands. It was my first 'I thought' real receiver. I think the definition of your 'first' receiver is the one that peaked your curiousity and then you continued in the radio hobby. That's the DX100 for me. Matter of fact, I went in the living room about fifteen minutes ago and turned it on to let it warm up. It's in mint condition, got the box and papers for it. Had a tech buddie of mine get in it with his equipment and he said it was just a tad off. I don't know how much a tad was/is. But I'll measure it with my DX399 hooked to a yo-yo antenna wire from Bil'ls company (that antenna has been everywhere and been put through crap) and match it up to see the exact freq. at it's always dead on. But it has to be on for about a good 45minutes to be stable. How's the drift on yours? When does it even out for you on your piece? Maybe fifteen minutes to half an hour and there's no noticable drift on AM. It never stabilizes enough to be "set and forget" on SSB. It will drift noticably with room temperature changes.

The ceramic IF filter didn't peak at exactly 455 kHz. The IF had a dip between two peaks. I was tuning it in on the bigger of the two peaks, but didn't take much drift for it to get detuned. I religned the IF cans to the peak of the ceramic filter, something like 456 kHz. Really very little difference. But after the relignment, I'm sure the bandpass was more symmetrical, and a drift of a few hundred Hz didn't produce so much audio distortion. No doubt the local oscillator was just as drifty as it always had been, but the tuning was a bit less critical. If tuning across a strong station seems to give an unsymerical response on the S-meter, a careful alignment may fix a couple of problems. It does "look" cool though.... And I'm sure making cool looking radios was a big part of the business plan of the Hallidrifters Corporation. Frank Dresser |
