• The CR-1a is not controllable over USB.

• Analog or digital IQ or IF signals are not ported to any connector at this time.

• LW (480 kHz-150 kHz): The CR-1a was designed to tune down to 500 kHz. The tuner is programmed to provide tuning to 150 kHz. However, there is no dedicated pre-selector in this range. The IF is also in this range and signals from other bands can be heard. The CR-1st performance is not guaranteed in this range and is provided for experimental purposes. Good performance has been reported from one CR-1st owner who uses an external pre LW-selector. Regulatory Compliance:

• FCC Mark Declaration of Conformity-Part 15

• CE Mark (Europe-elsewhere)

• RoHS: No PB Origin & Warranty & Satisfaction Guarantee:

• Designed and manufactured in USA

• Limited 1 year warranty: parts – labor – workmanship
