Hi.
in this circuit,


XS1 inputs 15VDC, and a 22KHz tone, and outputs 1GHz RF all superimposed.
XS2 or XS3 inputs RF and outputs 15VDC by the presence of tone or not.
It is a tone controlled SPDT switch.

Question is, if the tone entering XS1 will show up as outputting to (passing trough) XS2 or XS3 ?

Do not know the values of L1, L2, L3. Suspected very low, suspected intended to block RF.

 

Probably not. Each output is driven by two saturated switches in series. OTOH, circuit grounding is...different.
