Tuning BAOFENG /Repairing power supply

 BAOFENG

VHF/UHF UV-82L and similar models tuning procedure.

Switch on in frequency mode (to change from frequency mode to channel mode or vice versa, press the menu button and switch on the radio [continue the menu button pressed until the announcement is heard]). 

Use the Exit/AB button to bring the frequency arrow at the upper or lower row to select it. Select lower row for VHF channel settings.

Before selecting a memory channel no., be sure that the intending memory channel no. is free. Go to corresponding Menu (28) and clear the channel no. Now, type in the receiving frequency (at frequency mode), using the radio key pad, (on the bottom row or upper row). Press Menu > go to category 27> Press Menu button> give the channel no. you intend > You will hear the announcement 'Receiving memory' again press Menu button> press Exit/AB button>. 

Now switch off the radio. Again switch it on. Now type in the transmitting frequency (for repeaters plus or minus 600 Khz) on the same row, press Menu > go to categories like DCS or CTCSS for distinct adjustments and then go to category 27> find Memory channel option> press Menu button> give the channel no. you selected earlier for receiving frequency > again press Menu button> (hear the announcement 'transmitting memory') > press Exit/AB button > and come back to the home screen. 

Further, switch off the radio and open it at channel mode. Now, check the receiving and transmitting frequencies, along with the channel no. 

To register more frequencies on memory channel repeat the procedure at frequency mode. First save receiver frequency and next save transmitting frequency on the same receiver frequency memory. Before registering in a memory channel, please see that the memory channel is free. 

If for reserving a channel no. for simplex frequency also, use the same procedure. Here receiving and transmitting frequencies would be the same. 

Repairing Baofeng Power supply

Baofeng battery voltage is 8.4. SMPS power supply to the charging dock is 9.6 V. You can substitute the SMPS part with any power supply of similar voltage and current rating.

If the trouble is with the charging dock, disconnect the inner circuit in it and directly connect the supply to the contact terminals of the dock through two power diodes in series to the positive line. This is used to decrease the supply voltage from 9.6 V to 8.4 V.

Another option is  using a mobile charger. The mobile charger voltage is 5.5 V. Connect this to a DC to DC UP Convertor (available online) and increase the available voltage of 5.5 V to 8.4 V and connect directly to the battery (or 9.5 V if through the dock)

Good luck!
