Replaced fancy new card reader 1 year old with 10 year old Sandisk reader and it just works :-)

Replaced Arduino on rotator control again - think problem is spikes on voltage input from actual rotator at top of mast - put some buffering and decoupling but may be lightening induced? Have to see....

Fixed the RB-TV auto select - replaced 567 circuit with a simple transistor circuit to switch on the 22 KHz from MiniTiouner when signal present.

I wonder how long this will all work for?

Delivered the 23cms aerial auto switch system to Mike G8LES so he can build a standalone tray....
