MMDVM HotSpot hat for RPi type B
MMDVM HotSpot hat for RPi type B
HotSpot units, built by David S51DA and Blas EA7GIB. Thanks to both for valuable feedback and contribution of the photos!
This page is about homebrewing an (almost) easy to build MMDVM HotSpot module for Raspberry Pi - type B.
After successfully finishing three boards of those wonderfull miniature HS hats for Rasbberry Pi-zeroW, designed by Mathis, DB9MAT and Florian, DF2ET , I decided to draw a simmilar, however bigger HS hat board, that would fit a normal sized (type B) Raspberry Pi mini computer. Although a bigger size does barely mean an improvement when discussing HotSpot solutions, there is one big advantge - bigger board allows implementation of bigger and therefore easyer handleable SMD components.

The pirates are too dumb to copy our #MMDVM_HS_Hat board ... Please pay attention: This will not work. pic.twitter.com/MmUzY2zbS6

Just discover you can VHF (144-148 MHz) support for ZUMSpot by an external 18 nH inductor between L1 and L2 pins of ADF7021. This will enable dual band (VHF/UHF) operation.

How to Identify a Genuine MMDVM_HS_Hat:
How to Identify a Genuine MMDVM HS Hat by florian Wolters.
To help distinguish between an orginal #MMDVM_HS_Hat and a clone have a look at the two pics below. The first one is an original board revision 1.2 manufactured by us. It has the name “MMDVM_HS_Hat” on it in the upper right part. The silkscreen is properly placed and our callsigns are clearly readable. In addition to that there is the Open Source Hardware (OSHW) logo on the lower left.
The next picture shows the clone. It is only revision 1.1 and has misplaced silkscreen in the area of our callsings. The OSHW logo was removed as well as the “_HS” suffix on the name. Secondly it seems as if the RF parts are of poor quality. The picture is courtesy of Lindsay, VK2AMV.

MMDVM_HS_HAT Antenna Build
Case was the recommended for the #MMDVM_HS_HAT. Antenna is a Retevis soft antenna, selected because it was short and weight was at the bottom for stability.

MMDVM_HS_Hat project
The #MMDVM_HS_Hat hardware works fine. Was a fun project to build. Now to setup the radio properly. Thanks to the builders
Testimonial MMDVM_HS_Hat
My #MMDVM_HS_Hat works perfectly in the whole house! The hat is in the basement and i have good reception in the shack under the roof.
