[Elecraft] Disconnect FCTR probe after finished?

[Roland]

Last evening I read somewhat older artikel in this Elecraft Net.

Is it true that it is better to disconnect your FCTR probe after filter aligments are done?
My probe is still connected to TP2, this way I can always check/realign filter settings.
But the possibility is that you can get some spurs?? If so, what could happen?

Thanks for any thoughts.
