    50 Years of Power from a Battery? Sounds good to me !

    Not going to blow up like that, 3 volts at 0.033 milliamps is not even going to be enough to light an LED. Power from the aftermath of Taco Bell will be thousands of times higher than these "batteries".

    50 Years of Power from a Battery? Sounds good to me !

    100 microwatts per cell, you're going to need a lot of them to power your base station - 10,000 of them for every watt of power you need. Useful for things like spacecraft and satellites, but that's about it. Nice story though, does the rounds of the mass non-technical media press every few...

    Roadstar RS-309 info needed

    Hi Pierre, I've got two of these (both the 40 channel version), one working perfectly and in really nice condition, the other one a bit beat up but complete, not working (lights up and makes a hiss but no tx or rx) for parts or repair. Also have schematics on paper. Make an offer, don't want a...

    Hy gain Vlll mods

    Controller was an Arduino, available on amazon or ebay, synth came from QRP labs. The 27MHz crystal in the kit would have interfered with channel 4 and also was not quite stable enough for SSB, so it was removed and a 25MHz TCXO (also from QRP labs) was fitted in its place. No interference and...

    Programmable Oscillator for cb radio

    Tech said the same thing, as long as the programmable thing only injects into the "pll downmix circuitry" then it will be as clean as the original. Asked them about doing a cybernet ssb with the same method and was told not recommended as the unclean signal also goes into the radios rf...

    Programmable Oscillator for cb radio

    Local tech we use here has been using those things for a few years now to do exactly that, check out their page on the transmission1 site: https://www.transmission1.net/viewtopic.php?t=56500 SSB radios done this way have a clarifier range of +/- 1 to +/- 15 kc, you just program the range you...

    Uniden 980 Cracked?: Clarifier + Channel Mod

    Yep, wasn't going to say first but obvious to anyone thats had work done there. They are still doing this stuff, but have slowed down quite a bit since COVID. Some examples from them of using arduinos in old radios... Kraco base station: https://www.transmission1.net/viewtopic.php?t=56106...

    Uniden 980 Cracked?: Clarifier + Channel Mod

    The mod was on my radios but I wasnt the one that did it, way beyond my knowledge and abilities. It was way back in 2016 or 2017 sometime, so the post detailing the arduino radio mods might be long gone, they are/were on the transmission1 site. Go there and look back in the radio mods...

    Roadstar RS-309 info needed

    Sent to your email address, let me know here if you get them ok. If google/yahoo/hotmail etc eat them, I'll put them into a cyberlocker for you. First step in conversions is to find a switch that physically fits the radio. It probably wont match electrically but an eprom or micro can be wired...

    Roadstar RS-309 info needed

    Hatadi as a company and the switches they sold as a spare part are long gone. A tech will need to adapt one in. I know a couple that would have no trouble doing it, but if you are not in Oz the postage would be more than the price of the conversion. Post what country you are in and someone...

    Roadstar RS-309 info needed

    The roadstar RS-309 sold here was a 9 channel version (for the south african market, channels 19-27 only) but otherwise identical to the super jaguar. Early to mid 80's sometime. Easy to revert to a 40 channel model by replacing the channel switch which back then could be ordered as a spare...

    Roadstar RS-309 info needed

    Is it the same as this one? http://www.ozcbradios.com/cb-radios/radios-p/radios-pearce-simpson/502-super-jaguar-mk-ii If so, we have a scan of schematic and service manual. A bit crusty but readable, and better than nothing.

    Convert the extension cb jack to line out audio

    We had a couple of these boards made a few years back, about 1.5 inch square and goes inside the radio. One on a cybernet base and another on a cobra 148 side mike mobile. In both cases an extra 3.5mm stereo jack was added to give line out. Doesnt matter where the volume is set, the line out...

    Realistic TRC-458 Clarifier mod info.

    Here's how our tech told us to do it. Works well with shift the same amount in both directions and the 12 o clock position is at the exact center frequency. 1) The hot wire that originally fed rx only voltage is removed and replaced with a feed from constant 8/9v via a 100 ohm resistor. 2)...

    Uniden 980 Cracked?: Clarifier + Channel Mod

    No, you need 9.9568 to give you 40 below normal channels. But it will shift off center frequency every time you change channel, go up or down a couple of channels and you will have to reclarify to bring yourself back to 12 o clock position. Arduino mod did not have this limitation but that mod...

    Contacting Midland

    We never had the mains powered one down here, probably too much work to change the transformer to suit the local 240v house supply. The mobile version worked great but not much dx to be had when all the people interstate are waiting or calling on 35 (oz call channel since about the late 80s)...

    Channel number announcer for blind operator.

    Local tech here made something along those lines for a 80 yo diabetic whos sight went so bad he could only tell dark from light and couldnt use a phone or computer, and could not see channel numbers on the radio, think it was a uniden grant. No talking numbers, but 1 short beep when he landed...
