[hpsdr] Penelope + Munin + AL-811H Advice.

[Helmut, DC6NY]

Pete, any small 12V SPDT relay would be fine.

Hi Helmut,

Thanks for the advice and clarification regarding the use of the Open
Collector outputs.  I'll look into obtaining an external relay - can you
suggest or recommend a suitable device?
