    I bought the murs system with 4 transmitters and 1 base station transceiver.

    base station in the house
    2 transmitters on drive leading to house.
    1 transmitter each at outbuildings.

    instruction manual says mount transmitter 20 feet from area to be monitored. that worked very good for 3 of the locations.

    but for 4th location, an outbuilding, no preexisting tree or pole within close distance. so this unit is on a 4x4 post.
    ( I may change position, because i'm usually in high gear on the grass cutter at this location, and i'd hate to rip it off post!)
    post/transmitter is about 60 feet from outbuilding. excellent reception.. whether on a machine or walking the transmitter sends a signal to base station,
    and base announces "alert at zone 4" 3 times. I was surprised that it worked at that distance. the transmitter zapped me walking slowly for about a 20 foot width along
    front of barn (covers a roll up door area) I suspect this width would be narrower if it were closer.

    reading the manual after installations, I noted some specs that say reception area is 30 feet to 80 feet? this confirms my findings. I don't know why instructions say place transmitter at 20 feet, but i'm happy happy that a longer range is effective.

    distance to base varies.
    1 at 200 feet
    2 at 900 feet
    3 at 600 "
    4 at 650 "

    last unit was sending signals like crazy while I tested several areas and during installation.
    then it would not function... I think there must be a delay that triggers after so many responses... the wife was monitoring base as I checked for locations to install. she got frustrated listening to all the alerts... we'll let it calm down then try again.

    none of the transmitters have a clear view of base station. the 900 ft transmitter has to send through heavy trees, small open spots, trees, open spots, trees, well you get the idea... I may hear a slight drop in reception clarity on that unit... but just slight.

    so far, I'm real pleased with unit and value.
    i'm suspecting some deer/animals will set it off.
    we'll see.
    I didn't try to hide them during installation.. it will be easy to move them once we see how they work. 2 screws per unit.

      RR, There are a few jumpers inside to change some settings.
      One will adjust the detection range (3 settings), another will change time delay (2 settings), and another will change the number of times it says alert (1,2 or 3 times).
      I carry a handheld radio around all day, and I can here it alert over a mile away.

        dennis,
        thanks... can your handheld communicate verbally with the base?? I think it can... base has a ppt or something similar... push to talk I think.
        thanks.
        last night I was on the phone...
        alert zone 3 alert zone 3 I was mighty curious... but couldn't leave the phone...
        then another series of alerts at zone 3... that's a barn... but i'm sure a couple of dogs or deer wondered by!

          RR, yes you can communicate using the base station. Most ham radios ( including the Baofeng ) can be programed on the MURS frequencies and used to talk with the base station. You could also connect an external antenna to the base station.
          On page 5 of the manual it shows the jumpers for range(top left) and reset (top right). If you look under the cover shown in the picture you will see 2 dip switches that will change the number of times that the alert sounds. Just play with them to get 1,2 or 3 alerts.
