Zumspot not sending nor receiving

I had to redo my Zumspot configuration.

The Zumsport lights up green when I transmit and Pi-Star shows my call sign and the channel i am transmitting on

However , my transmission does not show up on the Brandmeister website and I get no response to my test transmission.

Any suggestions as to what might be going on would be appreciated.

I am using raspberry as my hotspot PW and have changed to that on the BM self help page

I am using a Baofeng RD-5R that worked well in the past.

From time to time the greeen light will flash on which makes me thing the radio is receiving something but nothing shows up on Pistar dashboard.

Raspberry Pi Zero W Rev 1.1

Making the presumption u've adjusted the rx offset for best available BER??

If the dashboard see you, login to ur BM selfcare acc go to devices and look at device logs. Whats reported there?

You also have the pistar live logs page which will reflect whats happening when you keyup.

Looks like an oscillator or TCXO on the HAT is not running, so the Pi is not seeing any data over the serial link from the HAT.
