I think you're trying to tell me that you can't handle the cockpit load - just joking. I thought that teaching the ADF/NDB hold was a good exercise for a student as it taught them about cockpit scan and discipline. Of course these days you can get the autopilot to do it all for you. I flew around Australia a couple of years back, some of the NDBs had a 150 mile range and it was interesting to compare it with the GPS. I agree the cost of ADF equipment is out of proportion with other types of kit and that the KR87 is probably the best available at the moment.
