I have to say the guys at BHX do seem to be very anti GA, I spend a lot of time around the edges of the zone and on occasions when I have called and been asked to Standby (Standard Reply) the frequencies are usually quiet. I appreciate that there are busy times when the GA aircraft cannot be dealt with but when it all seems the service from BHX is still next to nothing. I have on occasion monitored all frequencies and still been on Standby when all is quiet.
