So I'm still left with the original issue that the RBFeeder on my local RasPi is ouputting garbage on port 32088.
Please see attached 2 screen shots which show:
(1) Data received from port 30288 of RPi / rbfeeder
(2) Perfectly normal display on ANRB software
LATER ADDITION:
If you are still convinced that rbfeeder is supplyin garbage on port 30288, then it means during installation of rbfeeder, some corruption occured. In this case purge rbfeeder and then install a fresh copy.
IMPORTANT: Before issuing following commands, open file /etc/rbfeeder.ini and copy key from there, paste key on notepad, and save notepad. You will need this key when a new copy of rbfeeder is installed.
sudo apt purge rbfeeder
sudo apt autoremove
sudo apt autoclean
sudo apt update
sudo apt install rbfeeder
sudo systemctl restart rbfeeder
sudo systemctl status rbfeeder
