Have you checked the 2sc2166 or the 2sc1969? Those are the RF Driver and the RF Final output transistors.

Need to turn rf gain down inside uniden pc66xl c.b.


The radio should have a RF gain control on the front of it that should drop reception to almost nothing unless sitting side by side in very close quarters.

You could have the receiver detuned but that really makes no sense.

Transmits but does not receive. cobra29LTD Can it be a active copponent


where is the RF gain? It should be all the way up.

The other thing that can cause no receive. Its a common issue. If you have a mic with a broken wire in cord, if its the wire for receive, then when the key is released the radio will not go into receive mode. The switch in the mic determines weather the radio is in transmit mode or receive mode.

So make sure the RF gain is on max, and try another mic.

Clock keeps working plus 1 hour Lexibook RP200GB set the time but every night it resets to 1 hour ahead can't find user manual please help


Hope this helps I had same irratating problem
1. The RP200 is designed to automatically synchronize its calendar clock once it is brought within a range of 1500km of the Frankfurt DCF77 radio signal. When the RP200 is brought within this range, its auto-control mechanism will override all manual settings.
2. The clock automatically starts scanning the RF 433MHz signal after new batteries are inserted in the main unit. When receiving the RF 433MHz radio signal, the Radio Tower symbol starts to blink. A complete reception generally takes about 10 minutes, depending on the strength of the radio signal.
3. When the reception is complete, the Radio Tower symbol will stop blinking and remain solid
4. For an optimal reception, place the clock away from metal objects and electrical appliances (i.e. television, computer, monitor, etc) to minimize interference.
Notes:
• The unit will receive the RCC signals every day at 2am.
• The RCC signal can also be triggered by holding the key for 2
seconds in time mode.
• When the unit is searching or receiving the RCC signal (which lasts
about 5 minutes), none of the keys is working except the key.
• Press and hold the key for 2 seconds if you wish to stop to the
RCC signal search.
If the RP200 is brought outside the range of the Frankfurt DCF77 radio signal or if the signal is interfered, please set the time and date manually according to the instructions below. If the unit is located within the radio-controlled range, you may want to customize some of the clock settings.
Note: When no key is pressed for more than one minute, the unit returns to time mode (time, date and temperature display
World Time Clock
This function allows you to adjust the clock to a time zone. It is
particularly useful for travelers. Set the clock to the city you are located in, or to a city in the same time zone.
1. In time mode, press [MODE] twice to select the world time clock.
2. Press the key to select the city in which you are located.
3. Press to adjust the summer saving time function.
4. Press and hold [SET] to set the world time as the local time. When the local time is the same as the world time, the icon flashes.
