I asked about the 737 because you stated "All other planes work fine." Apparently, that statement wasn't quite accurate eh ? The other reason I asked is because the 737 and the Saab share the same sound engine. If the same problem exists in the 737 that would be a possible indicator of where the problem lies.
If any one else is reading this, and you have the Saab and 737, please let us know if you are experiencing this ATC problem as described above.
