[Elecraft] Upgrading K3

[Don Wilhelm]

Mike,

The KRX3A includes the 220uF Solid Polymer Electrolytic Capacitor on the 
output of the 8 volt regulator.
As far as I know, there is no other difference.  This capacitor allows 
extension of the K3 tuning range (with the modified KBPF3 option) to 
100kHz.  See 
http://www.elecraft.com/manual/E740264%20KBPF3%20Modification%20Kit%20Instructions%20Rev%20A2.pdf
If you have a KRX3 and KBPF3 to modify.

73,
Don W3FPR
