Is anyone using HAMshield?

    I agree and I think something like this has to be certified by the FCC.

    I don't see why. If a radio is in kit form, there is no requirement for type acceptance or other accreditation. This is no different from any other radio kit. The only problem is if they don't have some disclaimer that you need a ham license for this. I haven't read all the literature so can't say.

    This is an assembled board so, would it need type acceptance? In the instructables text it does mention changing the call sign to your own in the Arduino code. Much possibility for abuse exists with this product.

    When debates about certification and the like come up, the word from those who seem to know is that there is no type acceptance or certification for amateur radio transmitters. Receivers or really anything with a oscillator needs to be certified. This seems to be correct. I guess strictly speaking this (and any Arduino shield with an oscillator) needs to be certified for receiver radiation.

    That said, it looks like a cool device to play with. The main page at does say "You will also need an amateur radio license." in the "Skills Required" section. Half a watt is plenty to get to my local 2m repeater so I could make a useful transceiver with that. Of course I could also by a cheap HT for less than $99 but also less fun :)

    There's also a mini version.

    Just bought both, can't wait to mess with these.

    The name made me think it was some kind of jammer.

    Or condom.
    Prevent harmonics and minivans... ;)

    I guess I don't see this as any different from the MMDVM hat boards sold as accessories for Raspberry Pis, commonly combined to make DMR hotspots and repeaters.

    I think it's a great kit....a nd would love to work with it. Unfortunately, I've not mastered the art of soldering the components in this particular kit..... so I'll probably not build one.

    Exactly, less than a watt.

    I haven't seen anyone doing more exotic modulation with the hamshield like QAM or anything. So I haven't felt a need to reinvent the wheel at low power.

    Just noticed this thread and it could be the answer to a problem I've been working on. In order to talk to some friends a hundred miles or so away from home, I've been working on an Echolink hotspot - got it working fine with my FT-991A as the transceiver, but I can't get the 991 below 5W which gives it a range of several miles - more than is desirable for a personal hotspot. I will probably order a Hamshield Mini to build a dedicated hotspot...

    This is a must have for anyone that has Car Shield. :rolleyes:

    That would be really nice to hear some activity on 2 meters. Around here its all crickets, even the CB is quiet and I am well within ground wave from the big highway. Only have a scanner for 2 meters and higher frequency and between 2 major cities, its dead around here.

    Not sure why they even require a license to use VHF, that seems pretty out dated just like the CW requirement that was dropped. That is something the ARRL should initiate. Making it license free in the FM repeater portion of the 2 meter band and with a decent power limit like 50 watts or less.
