[ARC5] ART-13 Output Matching

[mac]

Fixed shunt capacitors are used by many people and a broad range of  
values all seem to give satisfactory results.  In ER#7, Nov. 1989,  
Walt Hutchens (KJ4KV) recommended 800 Mmf for 75M and 100Mmf for 40  
and 20M.  In ER#30, Oct. 1991, Bill Kleronomos (KD0HG) reported 560  
Mmf as being "ideal" for 160, 80 and 40M and 100MMf for 30, 20 and  
17M.  Don't remember exactly what values I finally settled on (caps  
hidden behind a panel) but use a single value for 75 & 40 and  
something larger for 160.  Tribute, I guess, to the broad range of  
variability built into in the ART-13 tank circuit.

Detailed breakout schematic of the ART-13's tank circuit in all it's  
switchable variations available on request.
