Grundig 750 or Grundig G3
I want to get one of them. The 750 is about 2x as much as the G3.
Anyone have a recommendation?????? |

You might want to have a look here at reviews on the G3: http://www.eham.net/reviews/detail/8447 Apparently, the Synch is not well-implemented, although it appears to be sideband-selectable. If that is a feature you feel is important, this may not be the right radio for you. AFAIK, the 750 does not have the S-AM at twice the price. Why every receiver $160 and up built nowadays does not have this feature, I have no idea. There are few receivers out there *new* these days that give you everything you need for less than $1,500; not sure why the radio companies cannot get it right. I wish you the best of fortune, whatever your decision. Bruce |

Grundig 750 or Grundig G3
Thanks everyone. I already have a G5 and it is indeed a good radio.
But I was playing around with the G3 at radio shack today, they let me take it outside, and it really shines on sideband ham signals, at least in the 14200khz range. I think having a separate USB/LSB switch makes a big difference.. But I didn't have my G5 with me to compare. I really wish I could see a 750 before I make up my mind, but none of the Radio Shacks around here stock the 750. I'll probably go with the G3 and use the G5 as a bedside radio. The G6 will be my primary portable. The 750 sits in the garage and is good for listening to FM outside. |

Operator Bob,
I guess the questions I am asking. Does having separate USB/LSB switch make a difference when listening to sideband signals? Will having separate USB/LSB along with synch detection make that much of a difference trying to listen to weak AM signals both on AM and shortwave? The Sony 7600-SW also is coming to mind. Anyone have any hands on with the 7600-SW? Thanks a mil |

Anyone have any hands on with the 7600-SW? Thanks a mil Separate LSB and USB, if properly implemented, makes a big difference. Instead of just providing a beat frequency oscillator (BFO) to allow you to tune in one or another sideband, the separate sideband provision is a more dedicated electronic approach. The result, in my experience, is a much cleaner signal. It definitely helps with weak signals. Does the G5 not do this for you? The SD for the AM is a nice feature for smoothing out a fading signal. The best of all worlds would allow for a double-sideband Synch along with sideband-selectable synch. This would allow for the greatest versatility when trying to get a good copy on a fading signal. Judicious use of the ssb can get you about the same results, but it isn't quite the same. Bruce |

Anyone have any hands on with the 7600-SW? Thanks a mil I have been using 7600G almost daily for ten years now. Not so bad as a portable, the audio a little on the weak side. But it does have synchronous AM and this is really unusual in a portable for under $200. The BFO control is very small and not convenient to use . Very sensitive front end and well designed in the cosmetic department. If the audio is connected to a good amplifier and speakers the result is an unusually clear sound (by SW standards). Sony could have taken this successful receiver and implemented it's circuitry in a tabletop . One of very few gadjets that is actually worth the price! |

Wonder why neither the 2010 nor the SW77 had it, or why it isn't on newer units like the G3? The 2010 is an interesting story. The ICF-7600D aka ICF-2002 had already came out, which was a much better (and smaller) radio than the ICF-2001. The then obsolete ICF-2001 design was sold to Sangean, who was producing them for Radio Shack and selling them under their own brand name ATS-803. Meanwhile Sony found that AM stereo had bombed and they had a warehouse full of AM stereo decoder chips with no one interesting in buying them. There were four competing systems of AM stereo and in the US, the FCC let the market decide. The market, as it were, decided that AM stereo was not something they were interested in buying radios for. A Sony engineer figured out that he could use the AM stereo decoder chip as a selectable sideband synchronous detector chip. The sync detector of the 2010 worked the way it did, because that's how it worked. No one said "let's design a sync detector" and made it that way, it was the other way around. The 2010 was a combination of the 2002's design, the sync chip and the 2001's ergonomics, put together to produce a new radio. It added some features (such as air band) that were not available before in addition to the sync detector. Eventually, Sony sold many 2010's and still had more chips, so they "improved" the 2010 and sold that as the SW-77. One of the noticable improvments was 100 memory channels instead of 32. From what I understand shortwave performance was not as good. :-( Eventually Sony sold out of the chips and since they had been manufactured in the early 1980's was unable to produce more. It would have required a re-design to use manufacturing techniques 20 years newer, which would have required a new radio design and there was not enough demand for it. BTW, the 7600-GR, is a descendent of the 2002 with similar size and ergonomics. Geoff. -- Geoffrey S.

If your experience matches mine you might have some difficulty getting the sync-det to lock on the variable intensity SSB signals but on AM it will make a difference depending on which side of the signal is being encroached. I guess you mean AMBCB and SW in which case the operation is the same. A sync detector is not designed to be used on an SSB signal. It is no wonder that you have some difficulty. A sync detector works by locking onto the carrier of the signal. In SSB there is no carrier. |

The sync detector of the 2010 worked the way it did, because that's how it worked. No one said "let's design a sync detector" and made it that way, it was the other way around. Considering that the Kahn system used independent sidebands there was not much to figure out. Left was one sideband, right was the other. The 2010 was a combination of the 2002's design, the sync chip and the 2001's ergonomics, put together to produce a new radio.

It would have required a re-design to use manufacturing techniques 20 years newer, which would have required a new radio design and there was not enough demand for it. But they had the chips for the 7600G/GR, so having a chip to make the radio wasn't the issue. Demand for a $500 portable was much lower than that for a $150 portable.
