Given your results and the price, the londoncolour antenna is a 'must try'. Also the extra cable length will get the puck to a window which should also help. The 1804M has already shown how stable my old HP107BR quartz standard really is. Not being a software person I must now go and learn about RS232s and terminals, (:-)

Thanks for your help,
