Albrecht ae4180 AM/ FM CB Radio repair manual... No transmit and receive...
I need badly a service manual or schematics for Albrecht ae4180. I just brought it second hand. The transceiver works, but the microphone has some PTT and connections problems. I tinkered for a while with the switch and pin connections. Unfortunately, I accidentally shorted something (I think it has something to do with the mic's center voltage pin and the RX-TX switch or input). An electronic component went on smoke, but I couldn't locate the burnt part or identify if it was a diode, a capacitor, a resistor, and an IC. I already used a magnifying glass to locate the burnt part, but all components seems to be intact (no cracks, no burn)
Please help. I know this is a German made CB Radio, and I already looked for documentations on the web, but they are very limited (and most of them ar written in Dutch language). I need to identify which part went up on smoke and possibly damaged.
My unit still powered up. It goes through channels 1 to 80, and with modified AM/ FM switchable bands on all channels. It has fully functional LCD display and switches. But no receive and transmit, though I can see a 1 bar in the RX signal indicator on both AM and FM band. The channel switching becomes too slow too, as a result of the damage.
I hope I could still put this lovely radio to work, just hoping that radio's microprocessor still works.

There is a solution to the problem. Join yahoo group SPECIFIC to your radio Make/Model, the technicians on that site will need as much detail as you can give them, so they can help you fix the delay issues. It's FREE to join and you can download manuals, schematics and other goodies for you radio.
When you say you used the software to download frequencies, do you mean as in from the internet, or did you have to input frequencies via the software on your PC?
There is a difference, that's the reason I ask.
If, by using the software you manually input the frequencies, then did you input both the output and input frequencies or just output for each channel?
If the latter is true, and you are trying to access another user via a repeater, then that is the error.
Repeaters generally, require both the input frequency = the frequency you transmit on, and the output = the frequency you receive on.
Without both frequency pair, you won't be getting out, and no won can hear you, as you are basically transmitting as a simplex station on a repeater allocatted channel, hence the error message on your display.
The radio you have is used by many amateurs & CB operators, and both group utilise repeaters within their allocated spectrum, excluding 27 meg CB, which is simplex only, but with SSB included.
Check your programming, and also check your battery. It will take more energy to transmit than to receive. Sometimes this is simply an indication of a bad battery. If this does not solve the problem, you might want to have your radio serviced. (Current flat rate repair is around $85 at dealers where this model is repaired.)
You either have a programming issue, bad/low battery, or your radio may be in need of repair. It takes more energy to transmit than to receive, so the first to go is transmitting when you have a bad/low battery. Secondly, this type of issue can be caused be a bad internal PTT, which is a common failure part on this radio.
1) You possibly have a bad or nearly dead battery. Transmit takes more energy than receiving. With this in mind, your radio's transmit will fail, if you have a poorly charged or bad battery, when pressing the PTT. Try a battery from a known good radio to see if it eliminates the problem. If so, replace your battery.
2) The radio is either programmed incorrectly or in need of repair. If you have been experimenting with the programmable features, we suggest you walk back through the steps of programming. Here is a link to the user guide: http://www.mytoolstore.com/motorola/rdx_userguide.pdf Programming instructions begin on page 36.
3) If in need of repair. Radios less than one year old should be under warranty, barring any physical or water damage to the unit. Contact the place of purchase or Motorola for warranty instructions.
If the radio is more than one year old you can get it repaired at any dealer offering Motorola repair. (approx. $85 flat rate)
The distance claims made by FRS/GMRS radio manufacturers are fairy tales. The frequencies that these radios operate on are line-of-sight only, meaning that ANYTHING between the radios (buildings, hills, trees, etc.) will block the signals. Unless you're transmitting from one hilltop to another, with nothing between the two, 2 to 3 miles is the maximum effective distance for any of these radios.
On your other question, FRS/GMRS radios and CB radios operate on different frequencies bands, so you cannot communicate between the two types of radios. In order to communicate with CB radio operators, you will need a CB radio.
The T6310 is a disposable radio. Assuming the programming is correct, and matching on each of your radios, and you are using good batteries, there is nothing which can be done to correct the problem. We would however, suggest you double check your programming, and also the age of your batteries.
Sidenote: Rechargeable batteries only last 18-24 months before they begin to fail. Signs of failure can include, but are not limited to, poor transmit, intermittent transmit, white noise, squelching sounds. It takes more energy to transmit than to receive, so your transmit would be the first to go.
I believe what you are describing is the TalkAbout 101. This unit is non-repairable. Schematics and parts were never released for this model. They are somewhat like a disposable lighter. You use them up and replace them when they don't work any more. (Sorry for the bad news.)
By keeping the PTT button pushed, if you get a rapid beep and the red led is blinking, sounds like a bad battery. Batt voltage is a nominal 7.5v. anything lower than 6.25v and the low battery beep starts. A rapid beep, and no red led blinking, an error in the transmit freq.
