The likelihood of DC going through it is even greater if it is solid state. You just have to verify that DC still goes to where it is supposed to when you install the ceramic filter. 73 ¨C Mike
Mike - It's solid state so no tubes or HV to worry about.? I've tested low-pass filters with my Nano VNA a long time ago and seem to remember that one channel is hooked to input and the other hooked to output.

Pete - I'll give that a try and let you know.? I also got another rare/unusual bird coming, an HE-43C.? I've never seen a CB where you transmit with crystal and receive by VFO.? What I plan doing is to put in a circuit that replaces the crystals with an Arduino controlled 5351 module.
