KPA100 High Wattage Resistors

[Ben Hofmann K1NT]

Should my 1W, 2W, and 3W resistors on my KPA100 be mounted pressed against the board, or should I leave some space between them?

Ben,

The ratings are conservative, so they can be mounted right down on the
board, but there is no harm in leaving a small gap - EXCEPT for the one
mounted on the bottom of the board - that one must go right down to the
board for physical clearance reasons.

Thanks Don,
   
  I didn't think of this until after I had mounted several of them, so I'm glad they can be mounted right down to the board.

Hi Group,

While I have already got a very nice LP100 from Larry,  WM1 could be good
for portable use.  From reading the manual, it should be able to link with
computer.  Will there be any linking cable supplied by the kit to link WM1
with the PC?  Where can I down load the program for the control of the WM1?

I am also interested in the AT1 step-by-step attenuator.  The shipping
weight of it seems fairly heavy.  It seems that it just consists of a few
resistors.  While the AT1 is so heavy?

Could anyone enlighten me?

Hi Johnny,

There was a typo on the order form and the weight was a little high for
the AT1. This normally wouldn't be a big issue since it is ordered with
other products, but when ordered alone for international orders, it
could make a difference in shipping costs. It is now corrected and is
listed at 0.5 lb.

Thanks for the notice!
