Many thanks Robert for the information. It certainly looks like a GPS
receiver can provide the time signals I want - in addition I can determine
the real coordinates of my observing site - the local survey map used shows
a "kink" in the road where my house is and I cant visually see any-the road
is straight!.
Ive done a bit of asking around and it would appear that the MAGELLAN GPS
receiver is available locally for about the price you mention, so now all I
have to do is convince my boss ( wife ) that its necessary for my well-being,
mental happiness and state of tranquillity in our house - doesnt matter that
the piggy-bank is empty at the moment!
Always nice to have a new gadget to play with.
Best wishes,
