Hi Mike,

Well otherwise this little laptop is fine. The batteries last for ages and ages once charged (6hrs plus), so I can easily do an evening on battery power. With a late evening charge it more or less runs overnight until breakfast. Nonetheless, thank you for the eBay tip.

Quite a few copied on 136kHz WSPR already this evening -  thank you all. Still to check OPERA.

Roger, Looks like you need a new laptop. Take a look on eBay where
you can find lots of 2nd hand laptops for a few pounds. Even quite
high end desktops are available for less than £100 ex-business.
