hello,
I consider this phasing ssb exciter schematic
../imgqa/eboard/Antenna/rf-qn0r23qqv1q.gif
(there is an error in the phasing network and in the divider circuit the frequency is not right but let's ignore this)
I do not know why this has all four phases connected to the balanced modulator simultaneously. I thought only two phases would be needed for either of the two sidebands. It has all four audio and RF phases connected.
How should the phases be connected?

How should the phases be connected?
- 80m phase shift SSB transceiver, How does it detect USB/LSB?
- ssb radio replaced VFO with DDS and the high-pitch noise started
- SSB generation by shifting audio spectrum
- SSB VS DSB in linear amplifier
- CA3083 vs TCA671 in ssb push pull linear, which one is more powerful?
- AD7008 can be used for SSB modulation?
