    Are you sure you weren't hitting the repeater? Hearing a short burst of static (called the squelch tail) after un-keying the transmitter is normal, and a sign you have keyed up the repeater. Unless you have a second radio, with a good (I.e. well designed) receiver, to use as a monitor, all you will get is the squelch tail, and maybe that awful roger beep.
     
    However, not all repeaters have squelch tails. So, in that case, you would have no indication as to whether or not you had keyed the repeater. Also, if the repeater has been quiet for over 15 minutes or so, and you key it up, it should ID itself. Though, again, while generaly required, it does not always happen.

    Great points!  I forgot to mention that most of my VHF DX stuff is upper side band.  Its a great mode.  The transceivers don't run as hot, have a higher duty cycle and are much more efficient than FM or AM.

    I would recommend you download the service manual for the radio and read through the manufacturers specifications.

    The first thing that pops up is the frequency stability is only 5PPM. I believe on the GMRS frequencies it needs to be 2.5PPM.
     
    The second thing is the narrow band performance. The better radios, typically the commercial radios, have two filters in the receiver section, one narrow band and the other wide band. They are switched in depending on the band width programed. The cheap Chinese radios, and most of the Ham gear from the major manufacturers, save money by using the wide band filter for both. The only thing that gets switch is the max deviation setting and audio gain, increased for narrow band. That means trying to operate with closely spaced stations isn’t going to work so well. 
     
    While the radio will “work” the poor frequency stability may cause issues with adjacent narrow band channels. All radios will drift in frequency with temperature. The better ones use temperature stabilized reference oscillators to minimize this. The receiver filter issue may result in interference from an adjacent narrow band station’s transmitter.

    When looking at equipment the biggest fault I find is the part 90 vs part 95 debate.  Esp when part 90 exceeds 95 requirements.  There are many business band fire / emergency service radios sitting on shelves due to narrow banding and they make great gmrs equipment.  Esp the repeaters.  Better and cheaper than part 95 certifications.  Glad there is a blind eye on their use. Untill you start causing problems....

    Me personally, I think the restrictions of type certified radios for free/public (not business or government) is completely stupid. I feel like most people don't know what is what and can easily end up breaking the rules by mistake.
     
    The truth is, I believe that while most ham radios are pretty cheap in quality, they are way better than any new part 95 product on the market today. Many of them are more than capable of performing inside the restrictions of GMRS. People should be allow to use them.
     
    That said, if someone is using one for GMRS, I couldn't care less, but I wouldn't go on the internet putting in writing that you are doing it and if someone asks me for advice in the forum, there's going to be a "by the book" response from me.

    Totally true. Usages cases are different for different people. Cobbled-together repeater with cheap diplexer works wonders in the mountains or in the woods where there is no RF interference. 10 miles - sure possible with tall antenna. Even more if you place your repeater in a good place, up the tall tree or high on the hill. Same system will be deaf and mute in urban or suburban setting.

    The responses don't surprise me. Seems counter productive towards getting people interested in a radio hobby.
     
    You want to talk money, we're currently burning in a brand new hytera ip addressable repeater going up with a DB420 antenna. Easily over $3k without counting duplexer, lightning protection, and cable.
     
    This will be at 950' in downtown Miami. Open to all. Part of the reason it's being done is the general "you stay off my repeater" vibe we picked up from looking at the local gmrs listings. It was baffling to see how unfriendly this side of the radio hobby can feel.

    Technically they CAN, but legally absolutely without a doubt "NO".

    I've read at least 2 or 3 people in here saying that a cheap cobbled together repeater is useless, just use simplex (what can you do with this that you can't do with FRS), and how you're not going to gain any range, it's way too expensive, and way too technical for most licensees, what are you going to get out of it ... I guess some people just started with a mountain of equipment, truckload of money, and all the know-how!

    You know what I get out of a cheesy sub thousand dollar repeater setup that I can't get from FRS? Almost 10 miles in any direction reliably to HT's. Oh, and unlike these fancy high dollar commercial setups I keep hearing about "needing" to make a useful repeater? It's not illegal. I also have fun building, and improving, and geeking out on techie things. Are you guys really getting 10+ miles simplex on HT's (on bubble pack FRS radios no less!)? I didn't think so because that would be absolute poppycock! I'm so glad I never listened to guys that kept saying "you can't".

    I'm not saying everybody should go set up a repeater, but the idea that they're useless unless you spend tens of thousands on a commercial type install (which again - is most likely not legal to begin with) is patently absurd. Not everybody has the same goals, or is in the same situation.

    Na. screw it.  Between you and the guy that said I need to get a part 90 frequency pair and run P25 with ASE256 and RAC to keep things private,,, I am in agreement.  Why should I care about other license holders. 
    And if I invest in a number of FB6 pairs, I can put up a commercial DMR system instead and sell time on it.   Who has time for hobby and family radio users anyway.  Thank you for helping me to see the error in my thought process.
     
    I will say that we need to quit hijacking this threat. 
     So when a Mod see's all this,,,, please clear it out until it's back on topic.
