I am publishing a new version of the mod-firmware and Amber firmware, including options for a partial upgrade of "moncs". Everything is in one archive along with the project documentation - there is a decryption of the system menu and manuals, all of the latest version. All new control options in the Debug menu. In addition to the improvements for TRX Amber, an extended adjustment of the suppression of the mirror channel has been added, which provides a guaranteed suppression of the mirror channel not worse than 50 dB on all ranges. If you activate the option "Improved I / Q Adj." in the menu “Debug / Exper. Settings ”, adjustment is performed on each range. Additional alignment points are marked with "*". Keep in mind, the adjustment must be carried out on each range, "OFF" does not mean the zero point, but the extreme value -128, with all the consequences. On the ranges of 160 and 80 meters, adjustment is required very rarely, but even if you do not see the line of the mirror signal, set the adjustment values to zero, this is important. Adjustment frequencies:
- 160m - 1.900 MHz
- 40m - 7.100 MHz
- 30m - 10.100 MHz
- 17m - 18.100 MHz
- 12m - 24.900 MHz
