A couple of weeks ago, I posted in a
non-photographic thread on "old machines" about the Realistic DX-160 shortwave receiver I owned as a kid. I mentioned how I didn't like modern receivers with their touch screen LCD displays and multitudinous knobs and buttons, and how I wish I still owned it, or could find another in "as new" condition.
Today, my Dad and I went to a local ham radio swap meet, and just as we walked through the doors I noticed a radio on one of the stalls, wrapped in a plastic bag (so not clearly visible) - but I thought I recognised it as a Realistic DX-100 or DX-100L (the most basic table-top receiver produced by Radio Shack from 1981 - 1984) - with a price sticker of GBP £20 (USD $25).
Assuming it to be a wreck at the price, I asked the stall-holder if I could take it out of the bag and have a proper look at it, and he was happy to oblige. Indeed, it turned out to be a DX-100L as I'd suspected - but in absolutely MINT condition... basically "as new", complete with original instruction manual. I asked him if it was in working order, and he confirmed it was - then played me a video on his cell phone, demonstrating it being used the night before.
I paid for it and brought it home, fully expecting it to have a few problems - but I figured I'd still have some fun with it, and wouldn't be disappointed if it turned out to be a lemon.
Well, it's *perfect*. Everything works exactly as it should... even the original orange back-lighting for the frequency display and signal strength meter! None of the knobs and switches are loose or noisy, and the audio sounds fine. And there really isn't a mark on it (see photo below - and the rest of the unit is just as pristine). Quite remarkable for its age.
For those who know a little about radio, it's a very simple design with rather limited performance accordingly. It's a single-conversion super-heterodyne receiver, capable of receiving AM, CW and SSB, with just one wide filter. The frequency oscillator has relatively poor stability, so it tends to drift, and the BFO (beat frequency oscillator) has trouble resolving stronger sideband signals. The tuning scale is fairly inaccurate, and quite coarse (even the fine tuning control isn't that fine). But, that's how it was designed, and this example I've picked up is working just as it should, warts and all
It sounds great on MW / AM - like a real analogue radio should (none of this digital signal processing nonsense!), and although I'll tune around the shortwave bands, I suspect it'll spend most of its time set to one of my local AM stations.
The DX-160 I owned as a child was a much better radio, but for what I've paid, I really couldn't be happier. It's a little slice of my childhood to play with, for £20
