[QUOTE="Llew, post: 1007412, member: 175007"] Had thought of that John, yes, but its boxed enclosure means it might be difficult to do anything useful, although you seem to have a little more space around the puck (I could open mine up a bit more no doubt). As to the puck's fundamental frequency, it's going to be somewhere around 9.25 GHz to give the original Hughes' x2 LOF of 18.5 GHz or thereabouts, so we're looking for a puck of <9.25 GHz to have any luck in spanning lower than it goes now. That's assuming the filters allow this of course. Cementing a piece of ceramic to the puck to lower the resonant frequency is one possibility, but it might be impossible here because of the screw head's proximity to the puck when screwed right in. We could try adding loading to the puck by increasing the screw's physical size ( a small half-nut screwed on the tip perhaps) [/QUOTE]
