[Elecraft] K3 Production Firmware Release (3.63)

[Don Wilhelm]

Rudolf,

Yes, you can safely upgrade without adding hardware mods.
You must leave CONFIG: VFO MD set to SPI1 (default) until after the K3 
VFO Noise Reduction  Mod has been installed.
That mod is not difficult - just 2 diodes and 2 resistors (all leaded 
parts).

73,
Don W3FPR
