Zumspot Nextion Pi-Star [Hotspot]
A couple of SARA members bought 'Zumspot / Nextion Pi-Star Kits' and we are sharing information and links for the setup here. Hamvention 2019 was a good time! Have more fun! Here are some papers and links to get moving with a ZUM spot / Nextion Display / Raspberry Pi 3B.
First, get this document: Ham Radio Outlet's ZUMSPOT 2.4 Nextion Startup Guide and follow their excellent directions, is is simple to get going. The following links are 'cleaned' and re-shown below for further reference.
Pi-Star is great software for digital voice hotspots and repeaters. It can handle DMR, D-STAR, and YSF, as well as P25, NXDN, POCSAG, and some cross modes when used with a multi-mode digital voice modem that supports those modes. Read about it in Playing with Pi-Star by KE0FHS, an additional paper on configuring and using Pi-Star.

In general, members found the ZUM spot easy to use.
Shiawassee County HSMM/BBHN
Highspeed Multimedia [HSMM] ~ Broadband Ham Network [BBHN] efforts are ongoing by individual members (not a 'club' sponsored activiity). Members provide the operating site networking for the club's Field Day activity. Usually three to six stations, each using a computer logging program on the 'linked system' for smooth operation. Networking details are captured here to assist members in keeping things coordinated for ease of setup.

- Router Setup ~ Details on converting Linksys WRT54G to BBHN.
- Shiawassee HSMM Standard ~ Standards for Shiawassee County BBHN for better linking support.
SARA previously utilized the BBHN hardware for Field Day logging and linking of the various station positions. It was a great way of keeping things synced up in the field. We did not continue to expand into a 'county-wide' BBHN emergency network. We decided we did not have enough resources to make it functional. We have thus closed the topic (for the foreseeable future).
