Project ⁽⁷⁾

The Wide Band RoF System works quite well, but some practical issues were identified after almost a year in operation.

Radio over Fiber is a well established concept by now, this is a look at a wide band multi-antenna receiver system with radio over fiber distribution.

The C-MAC STP 2373LF is a 2x2x1" OCXO used in e.g. the Epsilon EC2S GPS clocks. Since a number of these clocks were broken in obvious or subtle ways, I decided to reuse the OCXO's and other useful components from these.

The Furuno GT-88 is a GNSS timing receiver intended for precision timekeeping. These are my impressions after some testing, but before I've tried to build a full reference clock system based on it.

Token Ring is dead? Long live Token Ring!

Some viewers may have noted some 7-segment clocks in the background of some pictures in prior entries. I decided to update this system for the 2020 holiday season, and built 10 new clocks to replace 3 old ones.

This is an overview of my documentation for the Magnetic AB/Ericsson NMT 450 base station transceiver system.
