 All,

I have been asked if I could machine some heat spreaders for the Larcan
UHF (432) pallets that are available surplus.  The answer is yes.  I will
be making them from aluminum (no need for copper at this power level).
They will be the proper thickness to make for mounting the pallet on a flat
surface.  They will have the proper depth slot machined in them for the
LDMOS FETs and 4 clearance holes for mounting the FETs and and 6 x 2-56
tapped holes for mounting to the PC board.  I will also include (6) 2-56 x
1/8" screws for mounting.

The price will be $25 each plus shipping (likely a small USPS flat rate
package).

Please let me know if you want some and how many.  I'm going to leave this
open for 2 weeks.  So right after the January VHF contest I will order the
material.  Let me by no later than end of the day January 19th.  I will be
ordering the material on January 20th.  I'm making ONE "batch" ONLY!!!  I
will contact you when they are done and you can settle up then.

Thanks  and 73
