A few more decent hotspots have been released recently which are sat on various Raspberry Pi’s and running pi-star.
Two of the smaller hotspots running on the earlier Raspberry Pi’s are the Jumbospot and Zumspot. They use pi-star so accessing them requires a login via the devices IP address. They only connect to wi-fi (due to being on a small Raspberry Pi).
Now for those that wonder how they can connect them to wi-fi without LAN, some units come with a preset SSID and password so you can set your router or phone to the same SSID and password to get a connection then setup other wi-fi connections (home, office, other mobile…). There’s also an Auto AP system where the unit can be seen as a “wi-fi hotspot” – see section 3A via the link below.

The Jumbospot is in a small aluminum enclosure and contains a small OLED display to show the mode, talk group, call sign and IP address. Radioworld is selling these units for £100 – https://www.radioworld.co.uk/jumbospot-dmr-ysf-p25-d-star-multi-mode-ip-gateway
The Zumspot is a similar device except it can come in various cases and does not include an OLED display. The light configuration advises the mode in use. These retail at £145 from ML&S with a case – https://www.hamradio.co.uk/digital-modes-zum/zum/zumspot-rpi-rev-0-4-with-antenna-dmr-d-star-c4fm-p-25-nxdn-hotspot-pd-8982.php
Some of these hotspots can be found online such as via eBay and can sell for around £70.00 which makes them more affordable. I run two Jumbospots – 1 at home and 1 for mobile/portable use via my mobile phone hotspot. The instructions on pi-star are fairly easy to follow and there are plenty of people with good knowledge of these units and pi-star on the various DMR related Facebook Groups.
