RE: [Repeater-Builder] Re: if you have a commercial license
I've known of some private shops who wouldn't hire a ham because the owner thought hams did too good of a job. Those owners thought that hams took too much time trying to get the last tenth of a watt out of a transmitter or too much time tuning a receiver for that last one hundredth of a microvolt in receive sensitivity. Thus they spent too much time on a radio to be profitable. I'd been a ham for about 12 years when I got my first LMR job (thou I had previously done LMR in the military). After I had moved on to a municipal shop, I selected only hams as new employees including a Motorola contract person. I also was given the back room portion of the interview at a CB shop once. The owner gave me a radio to repair that no one else had been able to. I don't remember its problem, but I had it going in about ten minutes. I got the job and the owner was not a ham.

RE: [Repeater-Builder] Re: Key Collection
Did Fred use locks? Perhaps that was your point. I don't remember locks on the mobiles or upright base stations that I had. Seems like the mobile covers went on and off similar to the GE twin coffins (which I don't remember requiring a key). It's hard to remember the details of those radios except for the 7 volt tubes.

What's the key number or other stamping? Now I'm going to have to look thru my key collection and find it. Somewhere I have a picture of me sitting next to my Link six meter base station, but the radio and all the spare transmitters and receivers and the mobiles are long gone.

RE: [Repeater-Builder] Radio Mobile Deluxe Plot?
You would need to provide more information for us to run the plots. Including: Antenna height (looking at your website pictures I presume around 300') Effective receiver sensitivity (taking into account the noise floor etc) Duplexer, isolator and any filter losses. For the other unit, its receive sensitivity, power and height of antenna etc. Do you want talk-in or talk-out plots (they won't be the same). What kind of coverage do you want to plot? Such as 90% coverage, 90% of the time or something else. Take a look at the possibilities in RM. As you said RM has a very big learning curve with many different possibilities and it is very easy to get inaccurate plots. I didn't follow the part about how you have a picture file from a couple of weeks ago that you want to move to your site.

Re: [Repeater-Builder] More 6 meter repeater interference!!
Channel 2 may not go off the air on February 18. The entire NPRM is here: http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-08-281A1.pdf Harry, W0OZL 1. The Short-term Analog Flash and Emergency Readiness Act (Analog Nightlight Act or Act)1 requires the Commission to develop and implement a program by January 15, 2009, to encourage and permit continued analog TV service after the February 17, 2009 DTV transition date, where technically feasible, for the purpose of providing public safety information and DTV transition information to viewers who may not obtain the necessary equipment to receive digital broadcasts after the transition date. In this way, the continued analog service would serve like a nightlight to unprepared viewers, assuring that these viewers continue to have access to emergency information and guiding them with information to help them make a belated transition. This Notice describes the procedures the Commission intends to follow to implement the Act; the nature of the programming permitted by the Act; and the stations that are eligible to participate in the Analog Nightlight program. Stations that are eligible under the Act to provide nightlight service may choose to provide their own service on their analog channels, or may choose to work with other stations in their community to provide a comprehensive nightlight service on one or more analog channels in that community. Stations that cannot broadcast their own nightlight service can participate in a joint nightlight effort together with other stations in their community by providing financial, technical, or other resources. - Original Message - From: JOHN MACKEY jmac...@usa.net To: Repeater-Builder@yahoogroups.com Sent: Friday, December 26, 2008 3:54 PM Subject: [Repeater-Builder] More 6 meter repeater interference!!

Re: [Repeater-Builder] Colorado Gateway back on-line repeaters up high
I don't know the current situation, but for years the antennas were inside the building because the Forest Service would not allow them on the outside. Around 1971 when the 2m repeater was first installed, we couldn't even acknowledge where the repeater was located. At one time some years back, the concession at the top of the Peak and also on Mt. Evans west of Denver were operated by a ham's family. Bob is correct about the lightning. Many times I've had static buildup discharging across the end of an unterminated rf connector in a mobile at that site. Winds and also to a lesser degree icing are big factors on the Peak. Harry, W0OZL - Original Message - From: [EMAIL PROTECTED] the repeaters there use low gain antennas (I assume the owners are worried about lightning

Over the years I thought I had seen it all. That one takes the prize. Harry, W0OZL - Original Message - Here's a link to a photo I made during a recent service call. Someone has cut the Heliax to our UHF receive antenna and spliced a piece of RG-58 to it.
Re: [Repeater-Builder] Static on grounded feed line system.
I replace the Polyphasers at the sites I'm responsible for every two years, or sooner if a direct strike is suspected. Just because they pass RF OK doesn't mean they're still doing the job efficiently. I believe it is cheap insurance even it means replacing a half dozen or more at one site. I have recently heard that there is a new series on the market which may not require replacing except after a direct strike. I need to do more research on those. Maybe someone here has info on those?

Re: [Repeater-Builder] Re: Static on grounded feed line system.
I believe you could test them with a Megger, but you would also damage the device at the same time. If it wasn't damaged before the test, it would be after the test. That's why I have just replaced them rather than try to test them.
