ZUMspot Dual Band:

Board not found in Pi-Star or not working in a particular mode.
○
Go to
Configuration -> Modem
and make sure that “ZUMspot - Dual Band Raspberry
Pi Hat (GPIO)” has been selected.
■
If you can’t find “ZUMspot - Dual Band Raspberry Pi Hat (GPIO)” under the
Modem
list then you will need to reload the ZUMspot Dual Band Pi-Star image
onto the SD card.

Test using MMDVMCal. More information is found under the
Using MMDVMCal
section.

Test Tx and Rx with a UHF frequency and a VHF frequency. If both work then
any issues being experienced are due to a configuration problem or the Pi-Star
image has been corrupted
