Just a quick update on MB6IDR, Around 1 month after becoming operational. a serious fault developed with the node radio. this was replaced with a Tait TM8250 which has been running perfectly every since, In fact it is better than the Motorola GM340 it replaced! bit error rate is much better usually 0.0 to 0.1%
Apart from the hardware update. there has also been an updated the Pi-Star software and now FCS reflector access is available. see MB6IDR qrz page for more info.
finally a couple of pics of the node hardware:- Tait TM8250 + an STM32-DVM v2 from repeater builder/ N3XCC
