In respect of the PSU and undervoltage indication, I've always seen that but only fairly recently got the reported problems. I will check the actual voltage at the Pi but can you advise at what voltage does the Pi consider too low and trigger the undervoltage flag?
The Pi is powered by a dedicated 12V 2A d.c. adapter in my radio shack and fed up the mast by decent (1.5mm^2 if I remember correctly) cable to the ATOM Pi mounted inside a waterproof diecast enclosure 12 metres directly above. There it is fed to a 5V 2A linear regulator (LM317 if I remember correctly) and on to the Pi.
It is possible there is not enough headroom from the current 12V supply and I did change the feed from a 12V 8A ex-Tait PMR repeater PSU I had previously been using. I will do some investigation and probably swap back to the 8A PSU.
Thanks and regards,
Frank.
Thanks for this info Lee. I understand that most of the changes are with iGRID.
I'm interested in whether there have been any changes to the audio alerts?
We find that there are an excessive number of audio alerts for bearingless contacts which come through even though we have disabled them (see attached settings picture). We get multiple alerts “TRAFFIC NOTICE” “TRAFFIC ALERT” “TRAFFIC DANGER”- usually 1000'+ below, especially when near airfields. I'm not sure whether this is a bug or whether there is another way of disabling these?
Any help would be appreciated.
