Hi.
in this circuit,
22kswcirc.gif

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.
