Tonight I got MB7AEF the FM side working. It's not quite as polished as MB6IEF as I still need to make up an enclosure, but I had a successful FM to DMR QSO with GM7RYR, the keeper of GB7EE in Edinburgh who has kindly added the EMF Hub as a static Talkgroup.
The photo shows a rather messy "bench". MB7AEF is on top of the PSU to the left with MB6IEF on the right. Not shown is the Raspberry Pi or USB Sound Card.
