Hello,Sorry if this has been mentioned before,Flying in Russia today I have seen that some enroute ndb are of four digits for example 1290.0. This can not be tuned at the 747 by going to the NAVRAD page. I am getting an invalid freq message. But by drag and drop them in the FSNAV ADF window the adf is accepted in the FMC and tuned normaly.Is there any workaround that can be used to tune these NDB normally?Chris
