    My 847 is sickly. I have rx but its low. Way low. I can kick on the built in preamp and it goes up some, but overall its 10s units low without the preamp. Anyone got any good ideas? Nothibgs on that shouldnt be. No attenuator, cables good and all that. Thanks

    Lemm AT107 problem.

    Spacing between on an automobile

    We have tons of noise in town. Led lights, billboards and god know what else. Up to a 9+ in front of various stores. So my wonder was if anyone had tried the phasing qrm eliminator out in a mobile setup? I'm thinking about trying it this weekend.

    Pcb manufacturers

    So out of these outfits, is there one I can make a line drawing for and they would do the pcb lay out? I'm not familiar with laying out parts on a board. Point to point is all I've ever done.

    Why are mobile CB radios stuck in the 70s?

    After ssb and 40ch was lined out, what was left? The pll changed the game but other than digitizing like some imports what's left on the old designs to add? FM? Smt components have changed the ability to do much, processors have locked us into specific channels, parts so pitiful you cant peak...
