Can some one please point me in the right direction? I'm trying to calibrate the 144XV with the reference oscillator phase lock option (ROPLL) installed. The symptom is simple. When I attempt to do the (updated) frequency calibration on page 19 of the 144XV manual I get a N/A response, rather than a REFLOCK response. I'm tapping the "0" key many, many times. I get "N/A" and after a short wait it goes back to displaying the CONFIG option selected: XV1 OFS. I have verified the ROPLL option is installed by going through the process detailed on pages 9 and 10 of the ROPLL manual. The firmware install worked fine. I do get a "B001" response as intended to the "B" command. The 144XV status light is well behaved, blinking only once or twice at power-up (except when uploading firmware to it). There appears to be conflicting information between the two manuals. The ROPLL manual tells me to recalibrate the XV144 on page 11 by doing arithmetic on the K3's CONFIG: REF CAL value. The XV144 manual, as amended, on page 19 tells me none of that is necessary, and just to go to CONFIG: XV1 OFS and "tap the 0 switch until you see REFLOCK on the K3's LCD." The arithmetic approach did not provide great calibration (about 2 kHz off at 147 mHz), so I've been trying to get the XV144 page 19 instructions to work with great frustration. All help greatly appreciated.
