Hello,
I am retarded when it comes to radio equipment and was hoping someone might be able to help me out in my quest for a nice com. setup. I was looking at the Dakota stuff and like the base station and infrared transmitters for security, but am not to fond of the handheld's. I would like something more rugged for carrying. I read this article: http://www.itstactical.com/digicom/comms/the-best-kept-secret-in-radio-communication/ and this one: http://home.provide.net/~prsg/murs_faq.htm and am interested in having a MURS setup. I was looking at the Vertex radio that was mentioned in the article and when I go to their website ( http://www.vertexstandard.com/lmr/Portables/VX-230 ), it is listed as a VHF 134 – 174 MHz & UHF: 400 – 470 MHz, 450 – 512 MHz. From what I understand, I can buy the Vertex and have it programmed for MURS frequencies. Now for the questions: When they are programmed for the MURS channels, is that all they will work on? Or, would programming the Vertex for MURS mean that 5 of the 16 channels would be MURS? and what would the other 11 channel's be? That's all I can think of right now. Again, when I'm trying to read about radio's and frequencies, encode/decode, etc; my eye's glaze over. I will most likely have more questions following this initial post. I want to do it right the first time. Thanks for all of the help, Jake |

My radio is 1-5 murs 1 and 2 are secured. other channels include weather broadcast listen only and other local channels for listening.
Go here and click on database and find other local channels you could have programmed and listen too. http://www.radioreference.com/ |

Vertex makes a decent radio. You could likely get a radio from their marine division (Standard Horizon) that is just as good, and cheaper, and program it yourself. The Standard Horizon (Vertex Marine) HX370 is popular on the ham forum as a handout radio and comes with a aa battery case in addition to the rechargeable pack. It will also take 40 user programmed channels in addition to weather.
If you do not use all channels in your progam bank for murs, have the programmer add the NOAA weather stations and local ham repeaters (with transmit blocked) so that you can check the weather and monitor local 2M repeaters, which are often heavily used during emergencies. MURS is VHF, and all analog, no digital encoding or encryption, and channelized. There really is not much to understand about it other than that you program chose 5 channelized freqs into your radio with no duplex (different tx/rx freqs for repeaters) and talk to another MURS user. Walmart uses MURS if you want to listen to them and get an idea of how far you will reach. |

Jake,
Each channel is programmed individually. The radio can have from 1 up to 16 channels programmed. After programming, using the controls on the radio you will only see the channels that were used. You will not see "empty" spaces. It operates similar to a modern TV in that respect. You only see the channels you receive on your TV when using the "up" or "down" buttons. |

MURs is analog and open unless you are employing encryption such as voice inversion on up, which is not legal. |

Wrong choice of words. The radio outputs a tone before transmission. The other radio hears it answers. Ignores all other chatter. I thought that is what you meant. No doubt you understand, but it bears explaining for the post that what you are doing in no way makes the radios secure- it only serves as a nuisance limiter. Everyone else with no tone squelch activated can hear your traffic. |
