MMDVM radio will not connect

Post by kn6pyj »

New Pi-Star Installation, Aursinc MMDVM Dupelex Hotspot RaspberryPi Hat.
Everything looks correct.
Pi-Star: TX 438.4, RX 431.4, No talk Groups Defined (I.E. All allowed)
Radio (AnyTone D878UVII Plus): TX 431.4, RX 438.4, Talk Groups NorCal, Parrot & Disconnect.
When I key the radio nothing happens (no tone, no change in the display on the MMDVM Card).

There is nothing useful in the log (the radio was keyed a couple of times during the log time):

Code: Select all

And the Modem appears to be correct and has the latest firmware:

Any ideas?

Looks like the hotspot is set to Private mode whereas the IDs of the hotspot and the radio are different.

According to the config page, Node Type = Public.
I will have to research MMDVMcal some more (on initial view don't see the use here as I don't have a dummy load or a frequency analyzer).
The freq's are based on the Northern California 70CM Band Plan for Digital:
431.4 - 431.7, 431.8 - 432.0
433.0 - 433.6. 434.8 - 435.0
438.35 - 438.45, 438.55 - 438.75 & 441.5

unless I am mis-reading, 5MHz from 431.4 is 436.4 (which is in the Satellite Band).

after a log of googleing and trying different things. I am beginning to think my MMDVM hat is not working..
Even dug out a RTL-SDR Dongle, setup Gqrx in waterfall mode to monitor 438.4MHz, then ran the DMR Simplex Pattern in MMDVMCal, no difference in the waterfall display when transmit was on or off.

Any ideas on how to further test this? or just contact the vendor and ask for a replacement.
