[Elecraft] KIO3B

[Ed Muns]

"True" 45.45 baud FSK (with no bit timing jitter and near perfect overall
bit timing) is available via the KIO3B USB port, *IF* the logger or other
application program sends ASCII text via KY commands.  This is really the
best way to do FSK with the K3, or any radio.  Minimal cabling, no PC Serial
port, no K3 ACC port connection, highest performance.  Only a SMOP for the
application folks.  Elecraft has done their part of the system design quite
well, including properly filtered FSK for minimum bandwidth.

For FSK operation you need to use the FSK input pin on the Accessory
connector, the same as a K3.  AFSK, of course, can be routed through the USB
audio path.
