Simplex vs. Duplex Hotspot?

Post by k5fq » Tue Nov 05, 2024 3:08 am

Folks:

I have both Simplex and Duplex MMDVM hotspots built upon Raspberry Pi Zero 2 W boards with eBay sourced Hats. I use the WPSD software rather than the traditional Pi-star, as WPSD has more features, and is most importantly, actively maintained.

Both of these configurations work just fine, and although I have more than one DMR radio, I typically operate one at a time, on a single talkgroup.

I'm curious what others think the advantages / disadvantages of simplex vs. duplex MMDVM boards / hotspots might be?

Please discuss........

OpenGD77 will work with both simplex and duplex MMDVM based hotspots.

The you can disable TS filtering and this will allow you to listen on both Timeslots.


BTW.
This site is only for OpenGD77 firmware and CPS related things
