August 29, 2025: Featured in Random Wire issue 146 is the construction of a small digital hotspot with a Raspberry Pi Zero 2WH and an MMDVM hat. Build a hotspot for less than $100.
Calibrating your MMDVM hotspot for M17 was covered recently in an M17 Net discussion. The procedure was posted to the Kansas City Wide page on Facebook at https://www.facebook.com/share/19kzN7qciC/
Growing up in the 50’s on the edges of London, in a family that had been through the Blitz, my mum was always drumming into us the need to eat all our carrots (and of course, our greens) so that our eyes would see better at night.

Speaking of heatsinks, Nuts & Volts just published this: https://www.nutsvolts.com/magazine/article/choosing_a_heatsink
Also, if you're looking for an already built, tiny digital hotspot, consider the Dogbone: https://www.bi7jta.org/shop/dogbone-mini-hotspot-for-duplex-simplex-mmdvm-158
And if you don't want to source an RPi Zero 2 board and a hat, how about a package of those items? For $93, you get an RPi Zero 2 and an MMDVM duplex hat: https://www.bi7jta.org/shop/duplex-mini-hotspot-board-with-ceramic-antenna-84
