What a bunch of nitpicky old ladies are on here. Clive, I have an Icom R75, and although some will diss this radio, I can tell I enjoy the "bells and whistles" a great deal. The stability and crispness of the signal (both driftwise and in terms of AGC and S- AM) that can be achieved with this radio is quite nice. Did you get the crystal oven on that one? The S-AM on this set is only so-so, from what I understand - I would love to hear what the really good S-AM (on a more recent Drake, for example) sounds like. I've got sync on my Drakes, Lowe Ten-Tec and AOR. The difference is in the distortion during fades. There's less of it. The fades are still there, but the audio doesn't shatter. If you know what you're listening for, it's a big difference. If not, it's not that big a deal. I use my rigs without sync more than with.- Hide quoted text - - Show quoted text - Thanks, Peter - well, that's about what I thought - the Kiwa-modified S-AM on the R75 definitely helps soften the blow of the fades (the distortion disappears for all practical purposes), and the AGC when the RF Gain is turned back a wee bit fills in and remedies all but the deepest fades. I just figured the Drake/AOR/etc. did it better. Not having ever heard one in person (NOBODY sells or demos them around this metropolis), I just don't know for sure. In fact, you can't find any shortwave receiver sales at all anymore except the usual lowball Etons at RS. HRO has nothing but tranceivers anymore. Bruce It's no better, here. I have to go to a hamfest and look at mfr's rep booths to see, or to play with anything new. I bought my more recent receivers unheard, based on recommendations of users, and reviewers at RNW. Although the R8A I bought at a model train show. It was in like new condition. Not a mark on it. It still smelled like fresh circuit boards when I opened the box. That was a good day.- Hide quoted text - - Show quoted text - Model trains! Me too! :-D All I need is room for a RR...enough for a Challenger to hi-ball across the Utah desert... Yeah......um....my trains are a little smaller than that. |

Thread at rec.autos.tech newsgroup.Toyota blocks access to 'black box'
data. Somebody said he sees the Military buying field radios that Icom wont even provide service informtion on.They just pull the modules out and send them to Japan for rework. Lets me gits back to woikin onna mah hoyse now, teh front porch, them four big tall wood posts outch thar.Sanding, with my right angle electric drill with a round pad and round sandpaper.Y'all have seen ah billion uv dem befo. cuhulin |

It worked. And it worked according to factory specs. But it was what the techs at Lowe call 'fiddly' dialing it in was a job. And often more trouble than it was worth. I played with R75 at the ICOM booth at the local hamfest. Sync worked as described. But it took a lot of attention to keep it in place. * *The complaints did not go unheard. The rep I spoke to several months after the release of R75 told me that ICOM had heard the complaints, were very uhappy, and had made reimplementing the sync a priority. Trouble was, that the firmware for the rig wasn't readily upgradeable, and hardware modifications were going to be time consuming and expensive. R&D costs would have been a significant issue. And considering what ICOM went through with PBT on R71, they were not eager to step on technology that may produce another expensive and damaging legal skirmish. * *This at a time when SW was in sharp decline among broadcasters, and most users applying sync for broadcast listening, ICOM put the reimplementation of the sync on a back burner. * *I spoke to the same ICOM factory rep a couple of years later, and when asked about the sync on R75, shook his head and changed the subject pretty quickly. With KIWA doing the job, there was no motivation for ICOM to reengineer the sync, themselves, and with broadcasters abandoning SW, there was no reason to continue development of receive-only general coverage SW radios. Thanks - that's roughly the story I have heard. BJ |

Bruce When I used my R75 for program listening I used the SSB mode. *The SAM is useless without the Kiwa mods, which I don't have. Bingo. Actually, the Kiwa mods solve quite a few problems (The S-AM is only only one of them; the AGC time constant and the constricted audio are two others). The mods considerably improve the sound and performance on both AM and SSB. Now, I can enjoy Radio New Zealand on Friday nights with good audio and no fading distortion :-) BJ |

A couple of my old buddies are Train nuts.They own a lot of old Railroad
related thingys, including some Fairmont Speeders too.Wayyyy back in the olden days/many years ago, Ford built at least one ''Speeder''. Watchinnn WLBT 12:00 PM tv news,,, a hand grenade was found in a trash bag in a waste management garbage truck.Last week, there was an accident in the Jackson area, a garbage truck had turned over, I-20 lanes were closed down for a few hours.Cleanup on I-20! cuhulin |

A friend of mine is into radio control helicopters, and he puts down the cheaper plastic and partially CNC aluminum ones that do 99% of what his all CNC headed ones do, just not as precisely. I'm kind of thinking about getting one, but he's pushing me towards the higher end ones, and I'm thinking it's gonna crash anyway, so why not start out cheap? Then there's a friend who is into cameras, and buys another insanely expensive one about every year and a half or so. Pics don't look much different than when he had his 4 megapixel camera. Now he has an 18 megapixel (I think that's how many it's got)camera that costs what a used car does. -- BDK.. Leader of the nonexistent paid shills. Non Jew Jew Club founding member. Former number one Kook Magnet, title passed to Iarnrod.- Hide quoted text - - Show quoted text - In particular, camera megapixel size is REALLY overblown. Unless you're going to shoot for billboards to be examined at a distance of two feet, you don't need much over 6Mp. I have a 10.1Mp - because that's what they had at the time - and it is way more than adequate. I often find myself reducing it for manageability. As Peter has suggested and I concur, much better to put some $$$ into decent glass. That'll get you a lot more sharpness and resolution than doubling your pixel count. Bruce |
