[hpsdr] Spreader

[Bruce Beford]

Good going, Perry. 
The ATM (amateur telescope maker) solution. That is exactly what I plan to
do with my two Munin heatsinks. My spreaders are fine, and the heatsink just
needs a little rework. Technically, you only need to do the section that the
spreader contacts.
