Dan,

I'm finally building my DSP-10 kit, one of the ones that you put 
together for the first AMSAT buy something like five years ago.

(See http://home.earthlink.net/%7Ecbduncan/dsp10.html for the chronical 
of my ultra-slow progress.)

Tonight I did the FILTER_T parts.  Although 18 F numbers are listed (on 
two different part sheets and on the board):
F1, F2, F3, F4, F5, F101, F102, F103, F105, F106, F108, F109, F110, 
F111, F112, F113, F114, and F115, both parts lists say there are 17 
parts (the 470 pf  Pi filters) and there are indeed 17 parts in the 
kit.  Hmmmm.  To your and everybody else's credit I've put down nearly 
everything else and all parts counts have been exactly right until now.

Anyway, what should I do?  Can I order one (or a few) of these from 
somewhere?  Is there an easy work around just using a standard 470 pf 
cap of some regular sort?  I hate to put anybody through a big pushup 
for this.  Maybe I'll just start a shopping list.  For now I'm just 
leaving off F115 which doesn't look like a show-stopper, and leaving a 
note for myself.

Thanks for all the effort you put into these.  I'm looking forward to 
getting the thing on the air in the next two or three months.
