    Many of the topics you are asking about have been addressed in the past. Several times for some of them. I suggest you look at one site frequently mentioned on these forums when the subject of repeaters, their construction and use, is asked. That site is https://www.repeater-builder.com.

    The radios have to be more than 10 feet away from each other to limit receiver overload when transmitting.

    My suggestion is to use a 20-25W mobile for the base station. You can find a 15A power supply on Amazon that will provide all the power you need. If you get a mobile that has a cigarette lighter plug, then a mag mount antenna is all you need for moving the radio to your car in case of SHTF. A higher power radio doesn't buy you much more than a stronger signal in the same coverage area as the lower powered one, so don't think high power. more range. It just isn't so.

    There are a great many Part 90 organizations with multiple FRNs and licenses for the same physical location. Police departments are primary culprits.

    Are you certain the DB-25 is putting out full power? Also, measure the power from the radio at the antenna connector. You could have a bad connector at either end of the cable.

    I take it the aluminum angle work is bolted to the van roof so mounting the antenna to the center aluminum piece running crosswise would work. Virtually any metallic surface will act as a ground plane for an antenna.

    Narrowbanding was mandated after 1/1/2013 so any time in 2012 works as well.

    Perhaps if the major manufacturers had DMR radios the CCR market wouldn't have as deep an inroad into the ham market. Each has their own digital scheme and they are incompatible with the others. The CCRs provide hams with equipment that works across brands and, once it's configured, works well enough. Yes, they could buy public safety grade radios but they lack the flexibility to connect with a multitude of available DMR repeaters.

    The money paid for spectrum, like fines and fees, goes to the treasury, not the FCC. They only get the headache of enforcing it.

    There are several computer-based radio log book programs however, they are all targeted to hams.

    It'll be fixed in 5 minutes. (That's after they find the problem.)

    The main point will be to keep short bends out of the cable body and use some sort of boot or strengthening at the connectors. If your are truly worried, use an ultra-flex cable but you still need to protect the connector ends.

    That is like asking which radio is best. It depends on what's desired and what's needed. As you are the first in your area, you'll want an antenna that gives the best coverage over the area. That's why many use a DB for its radiation patterns, gain and reliability.

    I'm truly sad you had a bad experience with some hams. Try the local club for additional help and assistance on getting a license if you are still interested. The club president is Anthony Casciato and his contact is (414) 550-0444, email is KX3H.radio at gmail.

    Getting wet is probably the reason. Depending on where and how it got wet may have left debris inside or you didn't wait long enough for the radio to fully dry. Leaving the radio in a warm (100+) temperature for 48 - 72 hours would help ensure water was gone.

    You can also fix a metal plate to the fiberglass roof that's about one foot on each side through glue or bolts and use it. You can also drill through the plate to have the coax inside the cab. The ground plane for the antenna does not need to be connected to the body.

    Without a written opinion from the FCC the use of a Part 90 radio in Part 95 is strictly conjecture and should be evaluated as a personal opinion only.

    That's what we need here, more enginears, injuneers, engineerz, - well, you get what I mean.

    You can put the same entries into channels 20 - 22 freeing 28-30 for other entries but you wouldn't have names unless you can change the default name.

    Radio Reference is a site I barely used in 10 years doing Part 90.20 and 90.35 frequency work. A lot of the info on the site is available elsewhere but not as organized. If you want to know what frequencies are licensed for a particular agency, it is a good resource as some have multiple FRNs they use. Is it worth the money? That's something only a user could answer.

    As a great number of new users are joining every week with the same questions about tones and programming for repeaters, would it be possible to create a FAQ section with answers for these questions? More FAQs can be created for other common questions as needed if new users could be directed to that section.

    you can't change or set an offset on FRS channels and the repeater channels are fixed at +5 MHz.
  23. BoxCar
    You can also use a J-Pole as it has an integral ground plane.
  24. BoxCar
    I ask how much are they willing to pay me for carrying their advertising.
  25. BoxCar
    There's a difference in your scenarios than what you originally posted. In your scenarios he is not using the repeater to carry on a conservation with another party but attempting to contact the "proper" authority.
