The characteristics of the wire used and environmental conditions present will affect the physical lengths of the radiators needed to achieve the best SWR curve. If you build the antenna, be sure to allow extra radiator length to compensate for wire characteristics and factors such as ground quality and “capacitance” caused by proximity to trees or buildings. The extra wire can be left dangling at the radiator ends and trimmed as needed to achieve the best SWR curve.

Hey Dimitry! I'm just like you - brand new with a GMRS V-1 and a call sign. I do have the CHIRP software and a (good) connection cable. When I run the scan function (briefly), I don't hear anything. Yes I can get the local NOAA station. The repeater directory lists an open, free repeater about 10 miles away from me, but I'm not yet sure how to enter the settings. The directory lists 462.675 (Out), 467.675 (In) and 141.3 Hz. I'm not sure what the 141.3 setting is.

Hopefully this straightens this out for you: Fixed station: A fixed station, not open to public correspondence, operated by, and for the sole use of those agencies operating their own radio communication facilities in the Public Safety, Industrial, Land Transportation, Marine, or Aviation Radio Services. Base Station - A station at a specified site authorized to communicate with mobile stations. ENGLISH NOW: 50watts is your max Mobile, Base, or Repeater

I would try switching out for another CDM1550. I would also watch my battery voltage. SOME of the CDMs have had that problem where once voltage hits 11.5VDC the VCOs start to unlock and you get the beeping. Try another CDM, check voltages, reseat power connections on battery, verify inline fuse. My initial thoughts. -RF Medic
