    Here we take a look at the SHARI PiHatU from Ham Projects. This Pi Hat contains an SA818 Radio module to allow RF to the ALLSTAR network through a raspberry pi.

    Good Video Matthew! I noticed you were tuned into the morning brew net on the east coast reflector, node #27339. I check into that net almost daily. Good bunch of guys...
    Lots a great nets on Allstar which run throughout the day and several good technical nets to boot. Audio quality is alot better than DMR also.

    I have just the plain Shari(not the hat) and running it on a Pi3A+ which works great. Alot less power than the Pi4 and there is no difference in performance running Hamvoip than on a Pi4. Pi3A+ Board costs $25 and another $7 for the case. The Shari kit build and setup took just a few hours with the excellent documentation. The Shari and the pi run around $100 to have a full blown, portable Allstar node that you can tether it to any WIFI just like you would with a DMR hotspot. The nice thing is you can use any FM rig to communicate with and control it.

    Is this any different from an MMDVM hotspot that is capable of operating on D-Star, C4FM-Fusion, DMR, P25, NXDN, etc>?
    Or is AllStar a different network from D-star ?

    You need very little power. Surprisingly little. I can take my HT all the way around the (large suburban) block and hit my old Pi-Zero Pi-Star hotspot easily. Half a mile at least.

    A good bet are the Zumspots sold by HRO. The basic models are a thing of the past, however. My original Zumspot is still going strong after three years. The newer ones with the screens look nice...but a screen really isn't needed.

    AllStar is an analogue system, not digital. It's a derivative of technologies like Echolink and IRLP which connect analogue repeaters via VOIP over the internet...
