[hpsdr] Problems with direct connection PC-OpenHPSDR

[Kjell Karlsen]

Hi Scott and Georg.

First: This happened with both Protocols.

Usually I have had the IP address set  fixed to 10.0.0.xx on the SDR cards  
and that has normally been no problem.

I changed the IP address on the SDR card to 0.0.0.0 and now I am able to  
connect directly. The IP address on the SDR card is now 169.254.170.149.

If I connect via the switch, the SDR card get 10.0.0.61.

So now I am happy!!

Thank you both for the help.

73, Kjell
