Re: [Repeater-Builder] Re: GMRS HT recommendation?
Here's a question I've not been sure about: If a radio isn't Part 15 registered, is it even legal for ham use? If we build our own or heavily modify, that's one thing, but I think if it's a commercial product, it still has to meet FCC Part 15 doesn't it?

RE: [Repeater-Builder] recommendations on a good bandpass filter
Joe, I have two commercial UHF MTR2000 repeaters to each of which I have added a Telewave TWPC-4508-2 bandpass cavity filter comprising two 8 cavities. Both also have Angle Linear preamps followed by 6 dB attenuators to make up for the 1 dB or so loss in the filter and improve the sensitivity of the receiver. One repeater is about 150 feet away from an FAA ARSR-4 radar installation, and I wanted to be certain that so much power (at a much higher frequency, of course) would not desense the receiver. There are more than a dozen Government VHF and UHF radios at that site, but my repeater doesn't seem to be bothered at all. Telewave also makes 10 bandpass cavities, but a pair of them will not fit side-by-side in a standard 19 cabinet, so I chose two 8 cans. You can see similar filters here, except that the TWPC-4508-2 is not shown: www.telewave.com/pdf/TWDS-5018.pdf Bear in mind that a bandpass filter may be tunable over the 430-450 MHz range, but once tuned to a specific frequency will pass only a very narrow band, just a few tens of kHz wide. If you really want to pass a 20 MHz wide band, then you should use a preselector rather than a bandpass filter. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Joe Landers Sent: Saturday, August 08, 2009 11:44 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] recommendations on a good bandpass filter Hello Folks, Would like to see what people are buying these days and see what is recommended as I am in need of the following.

Re: [Repeater-Builder] Re: GMRS HT recommendation?
Walter, Part 15 covers unlicensed operation. As a ham, you're licensed under the terms of Part 97, which has specific rules for emissions types and purity. (97.305 and 97.307 in particular.) If you buy a commercial product not already certified to comply, and were ever accused of, say, spurious tranmitter radiation, you would need to be able to demonstrate to the FCC the means you used to determine its compliance, just as with homebrew gear. The test equipment needed is not in most hamshacks these days. But it could be done. A really confusing development in recent years is ham equipment which has come with Part 15 stickers on it. I have to assume that the stickers were a well-meaning attempt by manufacturers to cover their butts regarding the microprocessors used in running modern gear, and not the 10 mW cloning signals, since Part 15 operation is not authorized in the ham bands, regardless how low the power. 73, Paul, AE4KR - Original Message - From: Cort Buffington To: Repeater-Builder@yahoogroups.com Sent: Saturday, August 08, 2009 8:38 AM Subject: Re: [Repeater-Builder] Re: GMRS HT recommendation?

RE: [Repeater-Builder] Re: Narrow banding question
All true. However, I daresay that most of the non-convertible equipment has already been taken out of service, long ago. At least in my area, most users of high-tier equipment like Spectra, TK-990, and CDM radios are replacing them because they are getting long in the tooth- and these radios are already narrow-band compliant. Dual-bandwidth equipment first came on the market more than a decade ago. My gut feeling is that operators of large radio fleets will use the narrow-banding deadline as a convenient time to replace the entire fleet at once, not because of the narrow-banding requirement per se, but because they must re-program every radio, base station, and repeater they own and do it with minimum disruption. When you have 2,000 radios, it can take a week or more to reprogram the fleet. If you use the deadline as an opportunity to put new radios into service, you buy your 2,000 new radios a month in advance and program and bench-test all of them on the narrow-band channels. Just before the day you pick to make the changeover, you deliver new radios and chargers to all users, with instructions to start using the new radios on Monday morning. The radio techs will ensure that the base stations and/or repeaters are either reprogrammed or replaced just prior to that day. If well-planned, this will work. Obviously, users with many mobile radios will need to allow extra time for replacing them. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of N9WYS Sent: Saturday, August 08, 2009 3:36 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Re: Narrow banding question Albert, This depends on the service.

Re: [Repeater-Builder] 2M Vertical Dipoles
I'm sure someone on *this* list will be able to correct me if I'm wrong, but I think you can mount virtually any of the dipole type antennas on the tower leg as long as you're not looking for a 360 pattern. An offset or figure-8 pattern, though, no problem. In fact, I've done this for commercial users, and in some cases such as Low Band dipoles, that's the only way to can mount them. You might even be able to get away with it mounting one on each leg for a 360 pattern (with a little more gain in one direction for a 4-bay antenna), but your gain would be messed up since the signal would then be out of phase for each element in any given direction.
