This 70cm Microcontrolled Repeater was my latest repeater project. Build in 1997.
Based upon a 80C39 microcontroller. In 2004 I added a link to the 23cm repeater.
I designed the circuits and PCB's myself. Took me about a year to do the programming.
This Repeater PI2DZL located in Delfzijl was in use until 2013 and is now replaced by a new one.
First picture was our first 2M (PI3APM) repeater. I used a old Storno CQF 613 fire base station.
Modified it for duplex operation. Replaced the powersupply for a 230V one.
In the middle our first 70cm repeater. On the right the repeater controller I build (1993) and is still in use by three repeaters.
Below the 23cm repeater of PA3FZW with the same controller.
