    Antenna height is king with VHF/UHF.

    We did some simplex from Lancaster, PA to Columbia, MD, between two 5 watts HTs running rubber duck antennas.

    Oh, the HT was 3,000 feet above Lancaster in the back seat of a GA-7 light twin. :D

    What'd ya put up? Ham stick?

    Flew my Diamond CR8900 mobile quad-band whip. I figured it was the least likely to get snagged on branches going up or coming down.

    If it's raining tomorrow I may monkey with the cables inside and try to measure SWR. I didn't add a ground plane element (see snag concerns, above) so I'm expecting the impedance at the radiator is a little higher than ideal. However it's performing really well ... better than I had anticipated.

    MM: Is your raspberry Pi repeater analog only? Or are you using D-Star or Allstar?

    Today I bought a couple BF-888's and I have a spare Pi 4 sitting around not doing anything. I'd love to turn it into a D-Star node but having trouble finding a good tutorial. I see lots for Allstar though.

    Ideally I want to be able to use my analog HT to hit the 888 on the Pi. The Pi will then transcode that to d-star and send it over the internet. I know this is possible with Allstar but I haven't seen a clear use case with doing this on D-Star.

    Can you give me a shove in the right direction?

    I thought D-star was proprietary, and Allstar was the FOSS response to that. I haven't gotten involved in either, because putting radio on the internet seems counter-intuitive to me.

    My repeater is simple analog. I've been in contact with the Pirrot author, and he has pushed an update since I built my 888 repeater. More features, easier management through a local web browser interface. Good stuff.
