    Is it true that these pll's (5080 cci3001 are impossible to do modifications such as adding extra channels or unlocking the clarifier? What other rigs of this era used these pll's? From the little information I could gather Royce was one of the cb makers that used these pll's.

    I have a Royce 1-642 that I modded for channels and has an open clarifier. Wasn't too hard to do, but the clarifier doesn't unlock in the standard method of most radios. It takes a little extra tweaking to get it right.

    Channels on the radio go from 27.425 - 27.595.


    ~Cheers~

    here is a link to mod the channels for radios. scroll down to the 5080 PLL and it shows how to mod your radio for channels.

    Royce built some nice radios and they were a solid design.

    I had this radio in my younger days, it was a great SSB Base station.

    and who can forget the ad with the 40 channel mobile that they bolted to a paint shaker and let er rip.

    Try that with some of the radios built today and see if they work when you get done.

    That's a grate site. It's interesting too see how many rigs share the same pll's. Although I can't do the work myself its nice to learn about the different pll's and what mods can be done to them.

    Howdy Jeff! I got a kick out of that ad. I'd forgotten that one. Sometimes some of the poorly regulated power supplies on rigs south of the border make them sound like they're actually operating while they've got the ol' paint shaker running in full shake mode. LOL

    I like them. Specially the ones with the self contained PLL cans in them.
    They make great cheap signal generators.

    No Royce does not make a signal generator. "They" being the PLL cans from a Royce radio makes a good cheap signal generator. That is if you know how to modify one of them.

    From my good friend Lazarus,
    40 ch Royce like the 625 for example. Remove the PLL can or "sardine can" as a few like to call it. Put it in a box and wire it up, Build an attenuator and you have it. just need to ass a audio source.

    I just bought a 642 for 100.00 and it looks almost mint. It works great too and is stable as a rock on ssb. I don't think im going to mod it. Its just too sweet!!
