According to the instructions I see from an earlier post, you are probably only using one section of the hook switch to switch the line between L2 and C.  That would indicate that there is one section of the hook switch is probably not being used.  Use the section that opens last to switch the line.  The section that opens first could  be put in series with the receiver as is done in a 302 circuit.  You would need a tie point terminal to do that, but it would eliminate the hook switch pop.  If the dial is properly shunting the receiver there should not be a pop, but a varistor across the receiver wires would help.
