  1. Also to answer you other question, here is some good info for reading about frequency tones:

    Continuous Tone-Coded Squelch System

    Digital Code Squelch (DCS)

    CTCSS and DCS Tones -- What's the difference?

     

    btw - The "travel tone" is 141.3 Hz. Here is some good info about repeaters and offsets:

    Repeaters - RadioReferecne Wiki

    Offset - RadioReference Wiki

    For GMRS, the offset is always +5 MHz. A GMRS repeater operating on 462.675 MHz will have an input frequency 5 MHz higher at 467.675 MHz (which is also listed as a GMRS frequency).  Glad you're interested in the hobby - feel free to ask any questions!

  2. If you're calling another station directly, always start with their call sign first, then yours - ex " WYYY345, WZZZ123."  A good way to remember this is to insert "this is" between the call sign and you'll never forget the order - ex  "WYYY345 this is WZZZ123."  If you're not calling another station directly, the usual procedure is to announce your call sign and "listening"  or "monitoring" - ex "WZZZ123 monitoring."  If you're just monitoring simplex you might add "WZZZ123 monitoring GMRS channel 20."  If you're monitoring a repeater, you might say "WZZZ123 monitoring [repeater station name or frequency here]."  If you're looking for a CB-style radio check, people generally ask for a "signal report."  For example you may identify on a repeater like this: "This is WZZZ123 monitoring CityRepeater1, are any stations available for a signal report?"  A listening station may respond indicating the strength and quality of your signal and/or initiate a conversation.  If you receive no response, you could wait a few minutes, identify with your call sign again and request a signal report.  If you are not receiving any replies after one or two attempts, you should clear the frequency with something like "No contact, this is WZZZ123 clear, monitoring."  Also - you should avoid just keying up the repeater and not saying anything (a.k.a. "kerchunking" the repeater) .  If you just want to test if you're in range or have the radio properly set up, still identify - ex: "WZZZ123 testing."  Here is a link with some good info about amateur repeater etiquette, but a lot of it still applies to GMRS as well.  Radio involves a lot of listening, so keep yours on often and see what you can hear - hope this helps!

  3. I recently purchased a BTECH GMRS-V1 handheld radio and have been quite impressed.  This radio is a great option for someone looking for an affordable, repeater capable, Part 95A certified GMRS radio.  Perhaps the biggest advantage this radio offers is the ability to do split tones - a feature many other radios in this price range lack.  Read my full review here:
