From Serdar:

Dear Gang,
We setup our new NXDN repeater (VHF- R2- 145.650 MHz) to new location over the 17th and 18th weekend of August.

We linked this repeater to our other NXDN repeater (VHF-R7-145.775 MHz) which is located at our club building via 5Ghz link. Everything seems working now. In next days, we are planning to re-establish NXDN Reflector link via Raspberry PI.
