Ala Cuhulin, I picked up a Realistic DX-120 at a yard sale today for $5.00.
Anyone got any experience with these, or can point me at some related links? |

Not quite that clean. The only testing I've done so far it so plug it in to
make sure it lights up; I'll hook up a speaker & antenna to it this weekend & give it a run. Probably end up selling it on ebay, as I can't stand receivers with bandpass tuning!

Mike I can't speak for Lisa Simpson however I suspect that Lisa got into radio by first using a radio that has PLL/digital tuning and it has to do with being able to easily discern what frequency you are tuned to. Anyone remember making cheat sheets what it says on the dial vs what the frequency is, letting a receiver warm up then using a cyrstal calibrator to get the initial set point for the bandspread?? |

But on that level of receiver, it wasn't just a matter of "well the station is closer to the 5 than the 4.5" but the 5 wasn't even where it should have been. My first receiver, a Hallicrafter's S-120A (the "A" is significant because it was transistorized), I bought in July of 1971 and I spent all my accumulated allowance and birthday money on it. It was such a low end receiver that it didn't even have a place for a crystal calibrator. They were horrible receivers back then, and they still are, yet I think there is something special about them compared to the fancy receivers everyone has nowadays. Mihael |

Yup, quite true. Not against older receivers, like my DX-302, but
bandSPREAD (yes, I incorrectly said bandPASS earlier, I spologize to those of you that can't seem to get past that) is just stupid. wrote in message ...

You have obviously never used a radio with a proper bandspread. My Hallicrafters S-120 does it the wrong way - a separate Bandspread tuner and knob that you use after tuning the main knob roughly where you want it. My Grundig Satellit 2100 does it right. With the flip of a switch, it breaks out the standard shortwave meter bands - 25, 31, 41 etc . - and actually s p r e a d s them out, taking them from about 1 inch on the tuning dial to almost 6 inches each. The calibration is spot on, and it becomes easier than tuning in local FM stations. Where you had 5 stations in a quarter turn of the tuning knob, you now have 1 station in a half turn. Selectivity is incredible, and fading is largely eliminated - even without a sync - because you can get exactly centered on the signal so easily. Mike |

You are undoubtedly correct! The way it's done on these Realistics is just
asinine IMHO. Perhaps I need to experience a 2100. Do all the Satelit's have that feature? "Mike" wrote in message ... "Lisa Simpson" wrote in message ... Yup, quite true.

The 800's sync is much better than the R8's because the 800 has selectable sideband. The R8 is double only. Note I'm talking about an original R8, NOT an R8B! Mike |

Assuming you are talking about radios without digital displays, I should point out that they weren't left off old radios for some vague reason. They were left off because digital displays would require a huge chassis for all the tubes to make the digital display, and of course that would drive up the cost so it would be beyond the means of most people. You could go with a mechanical digital dial, but you then either have the National HRO (complete with plug-in coils for each band) which was expensive, but still didn't give linear readout. It cost too much, and was too complicated, to make each band linear, so the fine numbers on the dial were just really good logging scales (and reasonably decent readout). There were expensive receivers like the R390 that had mechanical digital dials. They fixed the problem by having the dial cover a fixed and small range (500KHz), and then adding a converter ahead of it to get all the bands. It was much easier to get linear tuning, so the digital dial reflected the frequency accurately, with such a scheme. But it cost money to pay people to get the tuning linear, and thus no hobbyist could afford those receivers until they were available in surplus. Note that the same scheme did provide pretty good dials without the mechanical digital readout. But again, it was far easier to calibrate the dial every 1KHz (and be accurate) when the tuning only covered a small range and didn't change when the band changed. In the old days, dial accuracy and precision went up the more you spent on a receiver. What's misleading is that solid state electronics have made digital dials easy and cheap and small, so much so that it's now easier to use them than trying to do an analog dial. But just because a receiver has a digital readout now doesn't actually mean it's a good receiver. They are just as bad as the low end receivers of decades ago, albeit with a better dial. A good receiver can be expensive. Michael |

... It makes perfect sense to have to guess at, or calculate, the frequency you're tuned to, when it would have been just as easy to actually display the actual frequency you're listening to? There is no guessing at all. The dial looks like this: 9 . . . . 9.5 . . . . 10 etc., and it's perfectly calibrated. Yes, digital is better, but this is one the best analog tuning radios ever made. I *much* prefer tuning an analog radio to a digital one. Way less noise, and just a better "feel". Look, I have lots of radios he E. H. Scott Allwave 23, a Drake R8, Grundig Satellits 650, 700, 800, 2100, Grundig YB400, Grundig S350, Tecsun BCL 2000, Kaito/Degen 1102s, Panasonic RF-2200, etc. etc. Digital radios are great for identifying a signal's exact frequency, but nothing beats an analog radio for just tuning around to see what's on!

They are both using their internal whip antennas, and are side by side on the table. The 2100 performs *much* better than the 800 without using the 800's sync. Selective fading is much less drastic. Turning on the sync on the 800 *usually* makes it perform better than the 2100, but not *always*. Mike |

Turning on the sync on the 800 *usually* makes it perform better than the 2100, but not *always*. You are comparing two radios with different circuitry and specifications. What you are seeing (hearing) is most likely a difference in radio performance. Speculating for a moment I could guess that the 2100 might have greater dynamic range or maybe a faster AGC that can follow the a rapid fade over the SAT 800 but there is no way I can understand the statement that precise tuning can equal using sync detection. Using a standard AM detector and tuning a station spot on compared to being slightly off tuned is not going to make an improvement in a fading signal that using a sync detector is going to make. Generally, I have found that precise tuning allows a sync detector to maintain lock on a weak signal. -- Telamon Ventura, California |
