LF: test this afternoon

["Mike Dennison" <mike.dennison@ntlworld.com>]

A successful test this afternoon has proved my new safety timer that 
cuts off the transmitter if it has been sending continuously for more 
than 7 minutes. This gives me more confidence to transmit overnight 
(after a worrying overheating incident a couple of weeks ago) and I 
will run some night-time beacons as soon as the weather becomes more 
reliable - more snow forecast here tonight.
