Spectrum Communications 900 Mhz transmitter SCT 1500 ... can someone point me to more information on it? Re: Spectrum Communications Equipment (900 MHz transmitter SCT 1500) Spectrum was an East Coast Company with probably the worst customer service record of any radio equipment company that every tried to stay in business long term. I will say my conversation with them 2 years back was pretty good... they were willing to at least support reprogramming a bipolar prom ID'er chip for me... be it a $50 each charge. I received a heads up last year the owner was trying to sell out and retire... but it seems no one purchased the Company and they closed. Spectrum Equipment is a love hate relationship with many people. I have a fair number of Spectrum Transmit and Receiver Strips and when properly attended to... they hold up fairly well. There are a few short-comings in some of their designs, which without decent customer support and resolution really pi$$ed a lot of people off. If you're a technical type and familiar with Spectrum Products they were nothing to be scared of when you could pick them up cheap enough. The 900 stuff was mostly paging and a small amount of Land Mobile two-way gear. Finding docs will be a bit of a beast but they can be found by asking people like me who have many of their product manuals scanned into free pdf files. Unless you can get it cheap and are willing to expect to have to work on it... it's probably better you steer clear of it. I tried to find the auction listing you mentioned but it had alreadyclosed. If you're trying to put a 900 box on the air... probably good to buy/go the converted Maxtrac or Kenwood radio path. If you want plug and play (no mods needed) the Kenwood TK-981 is a program and go radio, which makes a fairly nice repeater transmitter to drive a much larger RF Power Amplifier. cheers, skipp skipp025 at yahoo.com www.radiowrench.com

Joel, If you are looking for just a receiver Motorola made a nice Micor receiver in a 19 rack mount box. The only problem it was made to plug into their unified chassis mainly got get it power. I've taken these and built an AC supply inside. The box will hold a VHF or UHF receiver. I've seen these at Hamfest for $10. I normally use them for control rcvrs, but still work very well for repeater. They have a 5 cavity helical front end and were made to work in harsh RF enviorment. Not sure if you are into building up something like this for it does take a little work. Knowledge is king. Just takes a little work and you really learn something and get a very good piece of equipment. Spectrum is from the 70s when a Micor cost $1,000s and the tube stuff was still being used. It was easy to go with Spectrum for less than $1000 then, but today the Micors and GE Mastrs are real cheap; less than $50 for a complete rig. I've bought Micor base stations complete in cabinet with AC supply for $50.

You would probably be better off if they never shipped it. At least you could put a claim in with your credit card company, and get a real radio, instead of one that takes up the entire Spectrum.

[Repeater-Builder] Re: Spectrum Communications Corp
I've probably been into Spectrum Repeater Equipment as much as anyone else in this group. Technical wise, their stuff is not really that bad. The only big problem I've found with their transmitters is the use of non rf rated capacitors in the rf stages. I've mentioned the cap issue here on the group in the past. Spectrum is not the only Company making the non rf rated cap mistake... (Even one of the larger HF Amateur Amplifier Companies (Ameritron) uses non rf rated caps in some of their circuits.) I like their later version Spectrum Receivers quite a bit... a pretty good Technical Design and pretty well constructed. I buy some of their transmitters off Ebay and replace the mentioned problematic caps. A proper alignment, burn-in test and they do rock and roll a long time. I have one of Spectrum's original Dealer Demo 440 MHz self contained repeaters in service. Still works well at the rated output. Yeah, Spectrum is not so great in some business ways... but the late receiver and transmitter circuits are straight-forward designs that can be made to play pretty well. cheers, skipp You would probably be better off if they never shipped it. At least you could put a claim in with your Credit Card company, and get a real radio, instead of one that takes up the entire Spectrum. Yahoo!

[Repeater-Builder] Re: Spectrum Communications
All the Spectrum Communications badmouthing proves that word can get around when you treat people bad. With a few minor issues that I've resolved, I've had good service from most all my Spectrum Radio Equipment. Including a 224 repeater on the air for some years now. When you buy any used gear, half the battle is finding the circuit diagrams. Friends tell friends that used flea market electronic equipment is always caveat emptor, regardless of the brand. You didn't say how much the seller wanted for the Repeater, but for the right price, I would have bought it, fixed any problems and used it somewhere. At Dayton, there's just rows and rows of this kind of fun. cheers skipp Jeff Otterson [EMAIL PROTECTED] wrote: Hey, I saw that Spectrum 220 repeater, too. In fact, a friend almost bought it.

I called them a few months ago to get some info about crystal freq to get a pair cut and.yep there still there. Now if you wand a device that looks good and is a spread spectrum transmitter ( not by design) and looks good and performs like it was designed by someone that knows nothing about RF then buy it. It will give you many hours of learning experiance by trouble shooting it. If you decide to send it back for repairs you will learn not to give Spectrum your credit card number.

[Repeater-Builder] Re: Spectrum Communications SCR1000 VHF
FWIW: I posted on here a couple of months ago expressing regrets I had not seen all the Spectrum bashing before I acquired for resurrection, a Spectrum SCR-1000 220 repeater. I received plenty of cards letters from everyone with an opinion. (Ever see a ham without an opinion? I used to think that was a license requirement.I get the impressionthat is now the only requirement...But I digress.) BTW, Coy, over half of the incoming email was regarding legal actions against Spectrum and included contact information for the PA. Attorney General's office and other cases pending.I sent the exciter PA to Spectrum inAugust. The previous owner sent the PA to them to be tuned to the INPUT frequency of the repeater!!! I figured that was why it locked up and burned up the exciter. Kevin Schaefer, "Spectrum Sales Manager",advised they would retune the PA free, since I was getting a replacement exciter ($250).Odd how the only person I can contact at Spectrum is Kevin Schaefer. "Total cost would be ~$250-$275." Next conversation, (three weeks later), Kevin said it was going to cost "$325 to no more than $350". I approved the charge to my Visa, since I was committed this far. Three weeks later, when the Visa statement arrived, Spectrum had charged $432.50. I emailed and voice-mailed Kevin several times over the next two weeks, with no response. I copied Spectrum on an email to Visa to reverse the over-charge due to lack of response from the merchant. At 5:00AM the next morning Kevin was on the phone, screaming. We went the gamit of how they lose money dealing with hams, to he wasn't responsible for the over-charge but "would try to get the owner to approve refunding some of the money." Two weeks later Kevin called to report he had talked the owner into refunding $50 of the overcharge. Three months after sending to Spectrum and I still don't have the exciter PA back. I am eagerly awaiting my Visa statement to see if Spectrum has done anything. That covers their business practices. The quality of their work remains to be seen. Coy: Responses on this forum have been so numerous and strong. They seem to have overwhelmed my offer of SCR-1000 documentation.

Re: [Repeater-Builder] Re: Spectrum Communications, and other stability comments.
Hello Bob, Kevin wrote: 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. Kevin: I agree with your comments regarding component quality its importance for stability. Having said that, my experience with the G.E. radios is quite different from yours. I've had MVPs at sites that experience 100 degree temperature swings for over 10 years have seen no change in tuning of the trimcaps over that time frame. It wasn't my intention to place the GE line in the same category as Spectrum, rather to simply point out that inductor tuning has shown be be more stable over time than capacitor. To elaborate a bit more, quality radio manufacturers that utilize variable capacitor tuning use a good quality fixed value capacitor in association with the trimmer cap when larger capacitance is needed. This limits the 'range' of tuning and stability results. In the case of the Spectrum and other inferior brands, the values for inductance and the range of the variable capacitor allows for a very wide tuning range, but as agreed, at the expense of stability. If a circuit needs 50 pF of capacitance to resonate in the middle of the desired range, GE might have used a 40 pF fixed silvered mica and a 20 pF variable, where Spectrum simply used a 15 to 60 pF variable by itself. It has been my experience that GE Mastr II (and its variants) will 'properly' tune a wider frequency range than a Motorola Micor built in the same range, and is my reasoning that stability is then traded for tuning range. In other words, due to the 'mechanics' of tuning, the Mastr II is not going to be quite as stable as the Micor. Again, I'm not putting the Mastr II in the same category as Spectrum, but rather offering what I have found to be true. If you agree that the Mastr II will tune a wider range, then I believe you will have to agree with my theory. Kevin Your use of Yahoo! Groups is subject to http://docs.yahoo.com/info/terms/
Re: [Repeater-Builder] Re: Spectrum Communications, and other stability comments.
Hi Bob, [EMAIL PROTECTED] wrote: Coincidently, a friend of mine has an older UHF Mastr II RX (the one with tunable coils in the LO chain) in service that somehow got out of tune several months ago. My guess is that the tuning core wiggled out of place over a 10 year period. This might be the case in the GE radio as the core former is not an integral part of the coil (I believe they are a paper or fiber material that is glued to the coil). In the case of the Motorola Micor, this situation is not likely to happen because the former is molded from plastic and the coil is an integral part of the former. Also, the core is tightly fit into the plastic and the core itself won't move even when subjected to vibration, being mounted in the trunk of a vehicle. Kevin Your use of Yahoo!

That was the problem with the Hamtronics stuff. Trimmer caps were problematic.

Well, Budd, I finally got a response to my post The machine that I'm getting came from a police department, and was removed to nstall a voting system or something. YES I would like very much to get a copy of your docs. Besides we may be able to help each other keep these animals on the air and keep our ham licenses at the same time.

Yep Budd, It sounds like a good way to keep the house tosty this winter. I have MASTRII repeaters and I don't get to tinker with it because it just works and you know the old saying if it works don't mess with it.
