I have wiring details of how to fit the up/down/ASC buttons to the cobra mic & how to wire it for the cre 8900, if you need this plaese use the contact button at the bottom of this pageīelow are LED thermostats control boards mounted in between some Perspex sheet.Category Archives: cb radio romania Team Expert1 Software Does It All Too Novemcb funk cb radio cb radio with pc programming citizen band radio Qixiang Apollo ii software for radios team expert1 CRT-2000 HF Doktor “rU / Export Mode” Novemanytone apollo II cb funk cb radio cibi citizen band radio crt 2000 ham mode RU MODE team expert1 Team Expert1 More “Stuff” Novemanytone apollo II cb funk cb radio cibi citizen band radio team expert1 Team Expert1 Modifications Start Novemcb funk cb radio cibi citizen band radio crt 2000 ham radio Qixiang Apollo ii team expert1 Team Expert1 Funkshop Video Novemcb funk cb radio cibi citizen band radio crt 2000 funkshop video multi-EU norms team expert1 Lafayette Trucker Plus €134.95 Novem12/24V cb funk cb radio citizen band radio lafayette trucker plus multi-EU norms 2 Comments Lafayette Venus (Pro Version) €134.95 Novem27MHZ cb funk cb radio cibi citizen band radio lafayette venus pro multi eu norm radios CB Antenna President Florida UP Octocataloniamade antennas cb radio cibi CITIZEN BAND RADIO ANTENNAS president florida up ultra power grip Anytone Apollo II “On Air” *New Video Added* Octoanytone apollo II cb radio citizen band radio electret microphone. that I have done is to replace the battery with a 9v regulator, & conected it to pin 6 on the radio, it was 12v out but now 10.6v if you have been following I have also done the internal mod's found Or with out a fan, & just because the voltage has been dopped it doesn't mean that the radio can't get out, even at the lower voltage it still puts out the same amount of watts & draws the sameĬurrent one last thing you mite have to alter the battery under voltage setting in the radio using the usb cable & softwareĬobra HG m75 that I have modified with the three buttons chnnel up/channel down & auto squelch control (ASC). Conclusion is if the TIP 36c is moved & the voltage is dropped down to around 10.6v this radio will now work fine with The back now dose not go above 40c, with the fan running & without the running it only gets to about 55c & the right hand side barely gets warm. & keeping the mic keyed & at 10.4v the output of the radio & the amps started to drop, so I turned it up again to 10.6v the amps went up to 5.1 amps & the output went up to 6 watts. Radio output to 6 watts by keying up & put a amp meter in the line & it showed 5.1 amps, I then turned down the voltage (I have a adjustable power supply) I then got thinking about the 8 voltage regulator in the radio, do I need to to suppy the radio with 13.8v ? so I set the To get to about 50/60c with the fan running, & it would cool down when the radio was not being used, but the right hand side of the radio still got hot, not as hot I then after moving the TIP 36c I fitted the probe to the heat sink where it is now & the temp used Warnning sticker on case saying CAUTION THIS SURFACE MAY BE HOT. Used to be about 80/95c, the trouble is that there is no where for the heat to go & the top left hand side of the radio used to get very very hot, CRE even put a Before I moved the TIP 36c transistor I had the probe inside the radio next to the TIP 36c, the temperture after 25/30 minutes
it is controled by a thermostat that came from eBay (see last two pictures) top right you can see the temperture probe, The fan was fitted before I did this mod. To put some heat sink grease between the transsistor & the heat sink.
Here you can see I have soldered the transistor onto the wires & mounted it at the back of the radio using one of the heat sink mounting screws, you will need to Below is the inside my radio, you can see that I have removed the transistor TIP 36c & soldered 3 wires (yellow/red/black) to the board.
So I replaced it & the other transistors & voltage regulator, why, well they were all bolted to the same bit of aluminium that the TIP 36c was bolted to, so that they could beĭamaged as well, the cost about £6.00 for the lot. If you are here reading this then you may have had the same problems that I had with my CRE 8900 CB radio getting very hot, in fact mine got that hot it burnt out the
