When on approach to KMEM TUT2 I get a freq to atune to 123.15 and than later, a vew seconds, I get an other freq 126.7 to atune to.The latter is impossible to atune to and whatever I do I don't get it right again.The controler keep asking for the ack and tuning but that is impossble.So I had to turn to VisualApproach to land the aircraft.In the list the freq 126.7 is the correct one, the other- 123.15- doesn't appear in the list of freq for KMEM.You told me the last time that there are several app. controlers on this busy airport, but why can't I make the switch to the new given freq.It is acknowledged,but nothing changes.It keeps coming in the textbox to atune to 123.15I had this before and wrote you about it, but now it happens again.Is there something to do about this for it is very annoying on the approach when one has so much to take care of.RegardsCarlos

are you manually tuning? is autotune selected? are you doing a 1-ack and contact or a 7-ack?

Everything was set as it is in the tutorial 2.I have tried 1-ack and contact and 7-only ack, nothing changes the freq 123.15. The co-pilot was flying and I had choosen DV for delay pattern.For me it is strange for up to that point all went very well.I don't tune manual for it takes to much time and the controlers get impatient with me. Tried it in tutorial 1.

I have just repeated the flight from 30 NM from KMEM (TUT 2)and when I descent as I was requested to FL70 than everything is fine and I can be vectored to land.In this case I didn't need a second appr. controler.I think that it is when I need a second controler for the DV/HP that there comes the inconsistancy with the frequenties.Carlos
