Having zoomed the display in and out, I observed a discrepancy between the tuned frequencies on VFO A (3413 Khz) & VFO B (3446 Khz) and those displayed and measured on the waterfall, both traces being 8 Khz lower than tuned (see image).
This is probably an insignificant event (a glitch) and was simply resolved by restarting uno, but is perhaps worth mentioning.

Did you calibrate the RSP?

Thank you for looking Mike
No, it had not be calibrated recently, nor after the event and frequencies were and remain "spot-on" after the restart.
