hello,
I consider this phasing ssb exciter schematic
https://www.qsl.net/va3iul/Homebrew_RF_Circuit_Design_Ideas/9MHz_SSB_Mod_Phasing_Method_RSGB.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?
