![]() "gw" wrote in message om... Roy Lewallen wrote in message ... Thanks to Ed for the good advice. I've got an HP 140T. As far as I know, the only difference between it and the 141T is that the CRT in mine is a conventional one with long-persistence phosphor rather than a storage tube. It uses the same plug-in units as the 141T. I find it to be very usable, and don't really miss storage capability at all. I think the tube is a lot more trouble-free than a storage type unit. So I recommend that you don't turn down a 140T if you come across one -- and you might even have a better chance of getting a unit with a working display than with a 141T. Roy Lewallen, W7EL Ed Price wrote: [Lots of good advice] well it is amazing i think how some of these units retain their resale value even though the companies that made them do not service them or back them......man who was the brainiac that thought about how to implement this scam? Designing and building a product to provide many years of use, and then capable of being repaired without access to unique components and/or exotic service equipment, is a concept so rare as to be thought a scam.

Ed wb6wsn Imagine your cell phone if it was designed to be repaired, and used only common components. It would be the size of a briefcase. Do you think cell phones would be popular if they had to be briefcase sized? What about spectrum analyzers that needed to be contained in several 6 foot high rack cabinets? Is the world better or worse now that a 100MHz oscilloscope can be made the size of a paper back book? -Chuck, WA3UQV |

RMS Communications in Ocala, Florida rebuilds thousands of pagers and cell phones every week. I know several techs who worked there, and they were telling me about the equipment they had available at each work station. One problem with new RF and test equipment is the firmware programmed into chips isn't readily available to program replacement parts. Another problem is the short production life for some parts. If you build a product for over two years, you either do "Lifetime purchases", or redesign boards to use the next round of parts. What is real fun is a base product with up to 100 different sets of software, depending on the customers specifications. Its hard enough to keep it straight on the factory floor, let alone trying to do it in the field. -- Michael A. Terrell Central Florida |

The 'Sanford & Son' reference was made by the service rep, apparently referring to the gall of the OP, for wasting the rep's valuable time asking for information about equipment that he (the rep) considered to be nothing but junk (you'll recall the TV series of that name was about a junk dealer). Pretty obscure, but makes sense now. Does that wrap it up for you...or--OP--did I get that right? Got it all, thanks. Plain 'ol English beats speaking in tongues though. Actually, this was kind of fun. Maybe we should all start posting with obscure references and irregular grammar. Not. Glad to be of service. Actually I think the obscure reference was actually a paraphrased quotation of the service rep, which the OP repeated...probably should have used quote marks there to clear it up. jak -- Bill, W6WRT |

Most of the parts in a tek scope are off the shelf too, but like the cell phone, there are one or two show stoppers. For the cell phone, it is the microprocessor with its combination mask and flash programming. I know a guy that repairs pagers, but you cannot convince me that it is a profitable business.... The way he moaned about the cost of my fixing his RF signal generator gives me a clue.

It is even worse in the space field, where by the time a part is qualified, and a satellite is made, the part is stone cold obsolete. -Chuck |
