I checked the balance using my scope. The balance didnt seem to need any adjustment and the leakage measured the same as without the cap.
The cap was 0.1uf.
While a current burst through the diode unbalancing the mixer makes sense as an explanation for this I still don't understand why a 0.1uf cap in series would block the current flow if c122 wouldn't.
I really would like to find a solution to my ptt pop as I find it to be too unpleasant for headphone use.
Regards?
