D-STAR Hot Spot

D-STAR Hot Spot

Today I configured and installed the “ZUMSpot”. The ZumSpot is a pre-packaged Raspberry Pi Zero UHF Wireless multimode hot spot running the Pi-Star Digital Voice Dashboard. This is a Multi-Mode Hot Spot that supports several digital modes. K6HR will be setup specifically for D-STAR. My own personal D-STAR Hot Spot!

I’m certainly no D-STAR expert, more like a D-STAR noob. So I went to the setup video and followed along. This video made setting up the Pi-Star software and Kenwood TH-D74 a relatively easy task.

I quickly realized I would not have the ability to change reflectors via local repeaters, so I decided on the hot spot. Now I will be able to connect to reflectors directly. Since I have no D-STAR experience whatsoever, I’ll spend some time listening around first.

I’m certain everything is configured correctly, however on my first night of D-STAR…there was nothing heard on REF030C. I’m sure it will be active during the daytime hours! Hi!

UPDATE: It works! With the help of Toshen, KE0FHS, I was able to find an omission in my D-STAR registration details. After making the correction everything started working. I expect D-STAR will be very interesting! I may even consider other digital mode radios, since the Pi Zero is multimode.

This is a wickedly cool little device! Hats off to the Pi-Star bunch!
