Hi all, WSPR 4889 Bananian 3.0 is OK Fedora 21 on Banana Pi is OK Fedora 20 x86_64 is OK Ubuntu 14.04 x86_64 is OK
Thanks Joe. Virtual Memory requirements: 222056K on Bananian is OK with it's 1Gb of ram and 20Gb of swap. 370Mb on Fedora 21 on Banana Pi 800Mb on Fedora 20 x86_64 590Mb on Ubuntu 14.04 x86_64 All good. I don't have a Raspberry Pi because, no SATA port. When SD cards can do 10^9 writes without fail, I'll use them. (they are just not big enough, 32Gb is not enough for a general purpose computer) MRF646 Alan VK2ZIW On Sat, 10 Jan 2015 16:16:59 +0000, Bill Somerville wrote > On 10/01/2015 15:42, John Nelson wrote: > > Hi John, > > Not so sure about WSPR 4889 on a Mac.
