Re: [Flexradio] Calibration: Is this a bug in 1.4.5.18?
Ahti, It looks like the 10dB attenuator on the RFE board may not be working properly in the calibration. I'll have to try the calibration here to see if I get similar results.

Very difficult to calibrate the receiver. It would not calibrate at all on 14.200. I finally manage to calibrate it on 7 MHz. It seemed to try to use the noise level as the source. Consequently the noise level would be at -70 dbm, or -80 dbm depending on what the preamp was set at and the signal 73 dbm above that. 73, Dale AA5XE -- Government is not reason, it is not eloquence, it is force...Never for a moment should it be left to irresponsible action. – George Washington

Is this a bug or a new feature? The Level Calibration of the preview 18 with -70 dBm signal gives me following signal levels on the Spectrum display with different preamp gains: Off: -70 dBm Low: -80 dBm Med: -70 dBm High: -80 dBm If I transfer the mdb-file from the version 1.4.5.16, all gain settings show the same -70 dBm. 73, Ahti OH2RZ
