Some piano tuners calibrate electronic tuning devices using their cell phone. Is this a good idea? Calling up NIST on the cell phone, you can have 440Hz played to you. Is using a cell phone going to be a stable frequency reference? Will the cell phone network actually be able to preserve the frequency, say as 440.0000 Hz? or will there be frequency domain quantization errors due to wavelet compression, thus affecting the freq stability of the transmitted tone? Please post and email ...
