[hpsdr] Munin - minimum drive to achieve 100W output

[Lyle Johnson]

Dale,

Use ChipQuik and set your soldering iron temp to 250F or so.  Use plenty 
of liquid flux and flow the chipquik alloy onto the pads at T2.  No 
board damage and part will come right off.

Clean carefully using solder wick, keep the soldering iron temp still 
set very low and plenty of liquid flux and the chipquick residue will 
wick right into the solder braid (you can also use coax shield braid).

Wipe with alcohol, then solder the part down using regular solder and 
soldering temps.

73,
