[hpsdr] Beta release of linHPSDR

[Chris Smith]

Hi John

I realised that Fedora 20 was also rather ancient and updated to latest stable release F28. Same changes to the “Prerequisites for building" saw a very rapid build and install of both wdsp and linhpsdr. I must check my $PATH environment as I had to add a symbolic link to the wdsp library in /lib64 to /usr/local/lib.

I also sorted out the problem in my Tx chain and had a very nice QSO with an I1 station in Biella on 20m.

So, back on the air thanks to you and Warren.

Cheers & 73
