mmdvm useful setup references (Amateur Radio hotspot)

I’ve got a mmdvm board (Multi-mode Digital Voice Modem) on order – it’s an Amateur Radio hotspot for digital voice modes, such as DSTAR and DMR. While waiting for it to arrive I’m collecting together some useful links to help with the setup and config.

Excellent high level overview of digital voice hot spots in general: https://www.toshen.com/ke0fhs/hotspots.htm

WordPress error uploading photos on nginx: “client intended to send too large body”

Attempting to upload some new photos between around 3 to 5MB, the majority of the uploads failed, and this error was occurring repeatedly in my nginx error.log:

2018/08/06 07:18:37 [error] 43#0: *5 client intended to send too large body: 3125530 bytes

Based on this tip from here, the solution was to increase the default POST body size config with this setting in my nginx.conf:

client_max_body_size 5M;

Error installing Zappa on MacOS: “error: could not create /Library/Python/2.7/site-packages/requestlogger”

Attempting to install Zappa on MacOS with:

pip install zappa

I get an error:

error: could not create '/Library/Python/2.7/site-packages/requestlogger': Permission denied

Searching for this error I found similar errors installing other packages, and the recommendation seems to be to use the –home option to install to your home dir. So instead, this worked:

pip install --home zappa
