    Rarest cb / export you’ve owned

    There's a schematic and tune up info in Secret CB Volume 19. They've got the manufacturer listed as "Marco" for the schematic, but "Marko" for the tune up info. Looks like it's yet another Cybernet PLL02A variant.

    Found a Video on a Mod and wondering about it.

    It's been discussed here. https://www.worldwidedx.com/threads/dds-vfo.262744/ My personal opinion is it's a bit invasive. But if you've got an unobtainium PLL or VCO that's bad it's one way to get a dead radio back on the air.

    What electronics have YOU fixed lately?

    Had to replace my washer's water pump last month. Good luck to you in your endeavor.

    HTX-10 freq expansion with resistor?

    Wasn't that a Moody Blues song, "In Search of the Lost Diode"?

    CB FM Mode

    There's the DigiMax. Not quite as large a change to the radio as the DDS-VFO. http://www.circuitdomain.com/Shop/product_info.php?products_id=41

    CB FM Mode

    It is, but I don't think anyone has the same type of kit domestically right now.

    OKAY I NEED SERVICE MANUAL FOR COURIER CENTURION PLL 40 CH

    Spartan PLL is in Sams CB 191. If you ask Dan McClain for the Spartan info from that book in the "Sams PhotoFacts Collection" thread he may be able to help you. I say may because he may not have that particular book. If he doesn't, eBay probably does. One of the more experienced members here...

    Old uniden Grant PC409ac board

    MB8719 PLL chip marks this as a second generation radio. First generation were uPD858. So probably the earliest this would have been made would be about 1978.

    Turner Super Sidekick Recap

    I bought the kit from Klondike Mike (before I realized the little IC was the problem). The values in there weren't exactly the same, IIRC, but were as close as what's commonly available today will allow.

    Turner Super Sidekick Recap

    I use mouser pretty often. If you're willing to pay 7.99 for the shipping they'll sell you a single item. I tend to wait and do slightly larger orders, but that's just me. I look at DigiKey every so often and I have ordered from them at times, but I find Mouser easier to navigate. I only use...

    ARF 2001 microphone info wanted

    Well, that's interesting. Did not know that was an option.

    ARF 2001 microphone info wanted

    Going for the longshot. Looking for a schematic for the speech processor board that ARF stuffed inside the base of the D104's they modified. Even a reverse engineered and drawn on lined paper diagram would suffice. I'm guessing that the microphones themselves have been unobtainium for at...

    I Miss....

    I was in an antique store with the XYL earlier today, and on a peg they had Radio Shack packaged electronics. 555 chip, double flip flop, and a small audio transformer were what I saw, with more stuff behind those. They may have had more stock than the actual Radio Shack in town.

    JC Penney 6241

    There's a truth chart in Sam's 235. It looks a bit odd in that channel 1 appears to be all 0's. Until you realize that pin 8 has binary weight of 128 and is tied to +5V, and the N-code for channel 1 is 128. So there's no point in isolating pin 8, as it's already at a logic high (+5V). Why...

    I Miss....

    I miss turning on the radio and struggling to find an open channel.
