IMD is not Frequency Stability. ===================================== Bruce, does the IMD spec speak to audio clarity, off channel interference or both? IMD = Intermodulation Distortion A Spec for Transmitters, and it is a very HARD Spec to design for, and PROVE, via Type Acceptance Testing for General Coverage (1.8 - 30 Mhz) transmitters. There is a significant variation in parts used in the post Power Amplifier Filtering Systems, of these radios, and to get the required IMD Spec, for all these various filters and bands, for all the production radios isn't an easy trick, especially for the radios that you MUST submit to the FCC Lab for Type Acceptance.
