How to receive MSF radio clock signals in a "shielded" building.

In common with the author's Multi-channel Transmission System featured in the May and June 2000 issues, this project began with a request from the local Hospital Radio group. The group use radio-controlled clocks working from the 60kHz MSF signals transmitted from Rugby to assist with the synchronisation of some of their broadcast items. They soon discovered that these clocks were unable to receive the signal in their new studio, which is located in the interior of a large steel-framed building.

A way of overcoming this problem was required, so once again the author's services were called upon, and the project described here details his solution.
