pre-amp : update

Another couple of similar before and after passes:

With pre-amp (05:22UTC today)





















Without (04:53UTC  11/02/12)


















AOS and LOS seem respectively much earlier and much later - consistent with a few extra dBm arriving at the RX.

Definitely time to think about servicing the antenna and possibly getting the preamp up to masthead. I should really uprate the coax too - its only RG58.
