Wolf,
 
Try setting the rig to 499.99kc and use the RIT to go up into the 501kc band. No more attenuator!!! That’s what we do on 505-510kc here in the US.
 


Is the RIT control a stable input to the frequency synthesizer?

In some rigs it is a pot either directly driving an oscillator, or it
is an  ADC on the control processor where it is used as a poor mans
digital input.

RIT was originally intended to provide SSB offset, not the 1Hz class
stability that is needed for QRSS.
