The Spectrum equipment seems worse than any other, and the problem *may* stem from the quality of the original parts used. Motorola identified this stability 'problem' many years ago and decided to use variable inductors where they could. My Micor repeaters have stayed in a perfect state of tuning since installed, for many, this is getting to be 15+ years. The biggest reason manufacturers use capacitors for tuning rather than inductors is it allows for greater operating (tuning) range with no change in parts. In other words they can tune a greater span of Mhz with the same part values. This 'feature' is nice because some commercial radios will more easily tune the ham band and retain original specifications, but at the expense of tuning stability. The GE Mastr II is a great radio, and is very popular because it tunes most of the ham bands without much, if any, modification, but they certainly don't have the stability of radio sets that utilize inductor tuning elements. All of the Mastr II's I have, have required retuning during the same time frame as above, (usually one a year for optimal performance) but they too use variable caps for the tuning. It only stands to reason that something that is limited to certain tuning 'ranges' will provide better stability. Inductor tuning doesn't lend itself to being pulled too far, so making one of these radios that were originally configured for the commercial band tune the ham band is more difficult because part change-out is a necessity, but you certainly don't have to worry about the thing going out of tune. Spectrum purposely designed their equipment to tune from DC to light, and while you can make them work very well, just don't expect them to stay. Oh, to answer the rest of your question, in my opinion, every part of the Spectrum Radio is unstable, whether it be the receiver, exciter or PA. Kevin Custer Your use of Yahoo!

Re: [[Repeater-Builder] Spectrum Communication SCR1000 VHF Manual]]
I think its a combination of inferior components and poor design. The receiver is quite sensitive,but not very selective and overloads easily.

Re: [Repeater-Builder] Spectrum Communications SCR1000 VHF
Based on his enthusiasm for what lies ahead, I am betting they hire him if he can make it stable for a one month period. Then he can take calls from all of us about "why does it drift away so far when the tempurature only changes 15 degrees in that room?". And he can have a spinning wheel like the groucho marks show, but it will have only 2 parts - return the unit to the factory for proper alignment and align per factory manual or return to factory for proper alignmnet. If he is a careful entrepruner he will invest in a hardware company selling wingnuts and recommend they be shipped with each unit leaving the factory service department, this will expidite the returns to the factory for proper alignment enhancing revenue for both the hardware comapny and spectrum's tiring repair crew.

Re: [Repeater-Builder] Spectrum Communication et al.
Funny you should mention Regency. My nickname for them has always been "re-junk-cy." And while we're bashing different manufacturers of repeater equipment, there's at least one controller out there that is a real dog. Been several revisions to it, but it stays a dog. Need we go on about antennas. Some real scrap aluminum and fiberglass out there. Yet people continue to use these products and are happy with them. I guess to each their own.

[Repeater-Builder] Spectrum Communication et al.
Gee, they could have had a Genave... Back in the late 70's both Gatesville, N5DDR/R, and Lampasas, W5GFR/R bought Spectrum 2M repeaters. Gatesville had a phone patch, and Lampasas was stand alone. Both used single antenna, and WP641 duplexers. Lampasas is dead. Gatesville is still running without patch. Seems like there was a heat sink problem on DC regulator driver transistor, and some of the pretty pushbutton switches became un-reliable. Also periodic (once a year or so) frequency adj was needed. I do not recall any spurious transmit trouble or interference complaints. Seems there was nothing really outstanding or really bad - just that in 1980 they were pretty inovative. At that time MastrII was new, (ever give up on a 40W UHF IPA?) Mastr Pro was still current (FMR) RCA still had a CF1000, Moto had the Micor, and Aerotron was in the running. Also Regency had a 100 Watt box. We won't get into the E. F. Johnson line at that time (527) although the FleetCom II was a pretty nice box. BTW - Gatesville is still running, and Lampasas will be resurrected when time permits. It also seems like the 146.97 folks in Waco had a HamTronics that was a real problem child and spurious, and don't know what became of the station. Seems like they never got the problems solved.
