# This is a replacement hardware file for the Softrock and similar radios.

# Normally Quisk will change the VFO (center frequency) by large amounts, and perform
# fine tuning within the returned bandwidth. This hardware file does all tuning with the VFO.
# This creates a constant offset between the VFO and the tuning frequency. Specify this file
# as your hardware file on the Config/radio/Hardware screen.
