    Ali Express can be a real puzzle.

    They got me too once. They even sent me a pic of the "item delivered". The pic wasnt my home, Im guessing it was a stock pic from a company selling storm doors...lol . PayPal got me back, but I'll never buy there again....

    Cobra 138XLR gets recapped.

    C402 is in my 3 button Grant mobile its a 220uf in line with the PA jack audio, all the other boards use a single 470uf (C103) for both main and PA audio. I'm guessing it might match better while using a powerhorn for PA, as it cuts more bottom end. I had to look at the schematic when I saw...

    Tempting....?

    I have enough old junk that I can't find parts for, but that Stalker-1 in the pile makes this lot tempting. I'm just not keen on flopping down 200 bucks.... Especially for more stuff, the likes of which I'm supposed to be trying to get rid of.... Not mine, https://ebay.io/m/Eew96H

    Parts Needed / Royce 1-641

    I think the "3.5" in the schematic would be the uH value. I'm not sure if that is from 1 to 3 or from 1 to 2 and 2 to 3 ??

    Parts Needed / Royce 1-641

    Hi Brandon, I gave it a whirl. My fat arthritic fingers and eyes straining with reader glasses through a Harbor Freight lighted magnifier did their best. I had it working until it stopped & I had to press sideways on it to make it work. I pulled it back out and reheated the connections at the...

    Parts Needed / Royce 1-641

    I wanted to check if anyone had a "parts" or "Broken" Royce 1-641. I destroyed T8 in an ongoing attempt trying to extract a seized and broken cup slug. :sick: (A slip with a sharp tool, opend the winding) :mad: T8 and T9 are the same. I cant find a "positive" match online anywhere. Has ETC...

    955 v2 Service Menu

    In another post I found the 5555n2 service menu, It was a great help having something to reference. Using that other post, knowing that each S unit is 6 Db away from the next and that S9 should be -73 Db. Chanels 40 to 45 are the AM and FM settings and 46 to 51 are for SSB. I used unmodulated FM...

    If you were a pirate broadcaster, what's playing right now?

    Cool highway cruise song. I remember UFO would play super loud and clean on anything. I might have pirate shared this one before, If so.... Here it is again:LOL:

    Question requiring collective help???

    Personal mini repeater at one of the tops of the valley? ... Keeping consistant power to it, and the amplifier would be the tough part. Plus it's possibly on someone elses property, so...... I always wondered if a "passive repeater" or some type of reflector could help in these situations...

    955 v2 Service Menu

    This gave me an idea of who the last owner was. It was covered with duct tape. Did he use a fireplace poker for the conversion? All that's needed is grounding the top pad. I removed all the "whatever that was" and had to ground the pad at the beginning of it's trace, because the pads were gone...

    955 v2 Service Menu

    Well I was correct about the bias being fiddled with. The predriver had a constant 8ma, TX/RX (should be 100ma, TX). The driver had 900+ma, TX (should be 50ma, TX). The finals, RX is 10ma and TX was over 2A TX. (should be RX+20ma for 30ma). I know I'll eventualy replace the other 3 520s, just...

    955 v2 Service Menu

    Iv'e been trying to patch up a new to me 955. The 1st things I noticed were the Frequencies being out 1khz in all modes and bands, it displayed correctly but would need clairified to transmit properly. I was able to figure out and use the "BFO" and 'VFO" settings to fix that. Then noticed the...
