2.
Connect signal generator to mcHF (maybe via attenuator regarding output of
signal generator) or make sure you can receive your transmitter with sufficient
but not too high signal level.
3.
The mcHF is used to receive the
original signal in USB mode
, the
secondary
signal in LSB mode
!
4.
The signal generator is always used to
transmit
the signal carrier
at the given
frequency
!
RX Manual IQ correction: 80m calibration
1.
Set the signal generator to 3.601.000 Hz in the 80m band (If using a second TRX:
3.600.000 Hz in USB mode, activate Tune mode).
2.
Switch mcHF to 80m band at 3.600.000 Hz.
3.
Switch to
USB
mode. To switch use a long press on the Mode button.
4.
You should be able to receive the generated signal with the mcHF.
5.
Tune mcHF to 3.624.000 Hz.
6.
Switch to
LSB
mode (!!) by a long press on the Mode button. If necessary, adjust
+/- 500Hz for getting tone in reasonable frequency, if not right on spot.
7.
You should be able to hear a much weaker tone.
8.
Enter the "Configuration Menu", go to the "RX IQ Phase (80m)" setting.
9.
Now change the value so that the tone can no longer be heard or is minimal. The
direction to change values depends on your mcHF, e.g. you may need to set a
positive or a negative value.
10.
Once you found the minimum using the "RX IQ Phase (80m)", and you may still
hear something, use the "RX IQ Balance (80m)" setting to further reduce the tone.
11.
You may vary both settings alternatively slightly to find the best setting.
RX Manual IQ correction: 10m calibration
You simply repeat all steps for the 80m band. Only this time in the 10m band and using
the RX IQ Balance/Phase 10m settings. The initial RX frequency should be 28.100.000
Mhz,
USB
, signal generator set to 28.101.000 Hz (TRX: 28.100.000, USB, Tune Mode). The
secondary RX frequency for the mcHF is then 28.124.000 khz
LSB
(!!).
