  1. Well I finally got the system up, now to test and see how well it works, quick test with our portables, with stubby antennas and in the car was about 3-4 miles out and fine. Now to install the mobiles and get some distance test and possibly get a local shop to test the line to be safe and sure. http://i641.photobucket.com/albums/uu140/aussierescueil/Base%20antenna%202.jpg

    Morse ID Transmission

    To someone listening CSQ, an ID is an ID regardless of PL. If your ID is sent with PL, then people using a different PL wouldn't hear the use (unless RX is set to monitor). If the system ID's without a PL those using any RX PL will never hear it. Sent from my iPhone using Tapatalk

    Morse ID Transmission

    There has been an issues with repeaters that automatically ID. There have been situations where NOVs were issued for violation of this rule: 95.7 Channel sharing.(a) Channels or channel pairs are available to GMRS systems only on a sharedbasis and will not be assigned for the exclusive use of any licensee. Allstation operators and GMRS system licensees must cooperate in the selectionand use of channels to reduce interference and to make the most effective useof the facilities.A term: "channel camping" was created to refer to those who would send an ID automatically. Supposedly, this would deprive other users use of the frequency. Since an ID is not required, it could constitute a way to show "ownership" of a frequency. Just putting that out there.... No worries here either way.

    GMRS Band Opening

    The weather front that was moving into your area from the west created the situation. Occasionally when atmospheric conditions are just right, "tropospheric ducting" is formed. This is a temperature inversion effect created by a stable-high pressure system over oceans or very large lakes where a warm, moist air mass is sandwiched between two cool air masses. VHF and some UHF signals can be ducted through this conductive tunnel by bouncing off the dense air within the system to propagate waves for hundreds of miles. Think of it as mother nature's coaxial cable or waveguide. This effect is usually seen only during the warm weather months. UHF is defined as the range from 300 Mhz. to 3 Ghz., and along the shorlines of the Atlantic and Great Lakes, it is common to have this effect present several times each year where single repeaters and trunked 400, 700 and 800 Mhz. Public Safety, business and other radio systems in the frequency range hundreds of miles apart interfere with each other so severely that communications are all but impossible - lasting for minutes to several hours. This can be a very serious situation when a trunked system with the same control channel properties affects another system a couple hundred miles away. That is why it is essential to have a simplex backup plan in place during such events.

  5. It has been my observation in the past that when a Morse ID is transmitted with the repeater owner's callsign, that ANY questionable or unlawful usage of the repeater by either authorized OR unauthorized users, will be the liability responsibility of the repeater owner, since that ID may be the only one available to the Commission while monitoring for improper conduct. In order to keep a low profile and not be the target of a Commission inquiry, do not use automatic ID BUT require that ALL users follow regulation - 95.119(a)(1) and (2) regarding THEIR responsibility to properly ID THEIR communications. There are no regulations REQUIRING Morse ID of the repeater owner's callsign.
