// https://groups.io/g/BITX20/message/58951
|
|

|
|
// This may or may not be totally applicable. I believe it was for IMD/spurs on a pre-V5
|
|
// version of the uBITX. So it may be OBE for my V5. It also alludes to modifications
|
|
// to the transmit audio chain, which may be something I need to look into (i.e. increasing
|
|
// the gain on the initial mic pre-amp).
|
|
//
|
|
// Specifically, for the rig-out parameters:
|
|
// line out level 31 = 1.16 V p-p
|
|
// = 0.58 V peak
|
|
// = 0.41 V rms = 410 mV rms
|
|
// so output calibration needs to reduce that to 17.5 mV rms (70% of 25 mV rms)
|
|
// txMicInCal = 0.043 ... seems pretty low...
|
|
//
|
|
// Likewise, default line-in (TX) parameters assume consumer line level
|
|
// input, but with the default audio adaptor line-in level setting (5 = 1.33V p-p).
|
|
// line in level 5 = 1.33 V p-p
|
|
// signal in = 0.894 V p-p
|
|
// = 0.447 V peak
|
|
// = 0.316 V rms = 316 mV rms
|
|
// so input calibration needs to convert that to the 410 mV noted above (equivalent
|
|
// for the microphone), so that when that signal gets to the rig-out, it gets
|
|
// treated the same as the mic input.
