    I've got a BTECH GMRS-V2 and a Wouxun UV9PX and I can add a new repeater / channel to either via CHIRP or from the keypad. I see that there are Icom and Kenwood HTs supported by CHIRP (I don't see any Motorola radios on the list, unfortunately). Are there any Icom or Kenwood (or other "commercial") HTs that are supported by CHIRP and that can be programmed from the keypad?

    All amateur HT's can be programmed from the keypad. And you'll never see a Motorola that can be programmed via Chirp. Motorola has a proprietary programming system.

    i'd like to mess around with linking a repeter some day.  it wold be great if there was a box you could build that you litterally bring anywhere, turn on, it connects over wifi or ethernet from whereever it is, and then has a built in radio that becomes the 2nd remote repeater site.  This way, if you wanted to provide radio coverage in an area that has none during an event, you could just roll this preconfigured box up, and plug in and power up, then you're linked to home base.    of course, the internet or network has to be up and running for this.

    There is, it's an AllStar node with a built in transceiver. We run it through our phones mobile hotspot. Just need one at the repeater as well.

    Welcome to myGRMS.

    Yes, they use the same callsign as you. As @wayoverthere has indicated, you can add a suffix to end to differentiate different parties.

    Some ideas include.

    If you have two radios, one is a mobile, one is an HT, then you can use your call sign followed by ‘mobile’ and ‘handheld’.

    If you have a base and a mobile, you can use your callsign followed by ‘base’ and ‘mobile’.

    If you have a number of radios, as many of us do, you can merely put a unique number or letter on each radio and use that value as your suffix (‘Unit 1‘, ‘Unit A’ or just ‘A’)

    When I am communicating with my wife, we generally use a suffix (base, mobile, unit 1). But when I alone am on the radio communicating with others, I don’t use the suffix. The suffix gets used only during active communication with family.

    Yesterday I heard the wife of a regular GMRSr on the radio for the very first time. She appended “B” to the end of her callsign so I was able to immediately associate her as a member his family.

    Though I would refer to the handhelds as "portable".

    Not sure what to say, but a couple of pictures of a book doesn't show me understanding of the concept, but that's fine.

    In a nutshell: FHSS is a Frequency Hopping Scheme, or Frequency Hopping Spread Spectrum: which could be considered a combination of FDMA (Frequency Division, Multiple Access) and TDMA (Time Division, Multiple Access) in one package. Transmits for a few milliseconds on a given frequency, then it hops to another frequency and transmits again, rinse and repeat. Whatever frequency the radio will hop to next is determined by a random seed number, and a counter. So when both radios hop in the same pattern then you have a viable radio link, but when they do not, the two radios can't talk to each other, nor have a clue that another radio is even talking.

    At any rate, my vote goes for FHSS, just like the DTR radios in the 900 Mhz band have already proven it works very well.

    Again, I am also NOT endorsing Motorola radios either, just making a reference to their FHSS scheme.

    Also, military grade radios use FHSS as well, for all (but not limited to) the reasons I've explained.

    You will not see freq. hopping on GMRS or Amateur. If GMRS goes digital, it will go just like Amateur Radio did. Proprietary digital, proprietary digital, DMR, APCO P25. And when you hear it, you won't be impressed. At this point in the game, P25 has the best audio and is easiest on the ears (and that's not saying much).
