When I bought mine the cable came with. Call Radioddity and ask them to send you a cable.

I found this online and it may be somewhat out of date, but try them:

Some Operational Tips:

Open up the Ham 2 meter and 70 cm bands to transmit on the USA version:

1) Turn off the power.  

2) While holding down the V/M button, turn on the power.  Use the Up and Down arrow keys to change from the GMRS setting on the display to 136-174 MHz; 400-470 MHz and now power down.  

3) When you power back up licensed operators can now transmit on the GMRS channels and the 2 meter and 70 cm Ham bands. 

NOTE: This can easily be accomplished with the provided software too.
----------------------------------------------------------------

Giving a Channel an alphanumeric name without using a computer:

1) Go to the appropriate Channel

2) Push the FUN button and using the V/M and MAIN buttons to go through the Menu items until you reach Function 29: DSPCHANNEL and using the Up and Down arrow buttons, select NAME. Push the FUN button to exit the Function menu.

3) Push the FUN button and using the V/M and MAIN buttons to go through the Menu items until you reach Function 12: CHANNEL NAME.  Using the Up and Down Arrow buttons, scroll through the list of 1-0, A-Z and a-z to find the first letter.  When you do find it, push the MON button to confirm that character and move to the 2nd position.  Repeat as necessary until up to 8 characters are entered.

4) Save the NAME to the proper channel by pushing Fun and UP on the microphone and then use the UP and DN keys on the mic to scroll to the proper channel number (and frequency noted at the bottom of the screen).

5) Save the NAME to this channel holding down the "MON-*" key on the mic.

6) Push the FUN button and you are done!
----------------------------------------------------------------

Programming a repeater channel without using a computer:

1) Switch to VFO mode (from Channel Mode) using the V/M key

2) Using the number keys on the mic, enter the repeater's output frequency

3) On the mic, push FUN then 9 repeatedly until the proper split (+ or - or blank for Off) appears above the frequency.

4) Press the FUN key on the Radio and use the V/M and Main keys as an up/down to get to function 10:Offset.  

Use the Up and Down arrow keys to set your offset split, such as 5.00000MHz or 0.60000MHz (you can hold down the Up or Down key to have it continuously change). 

Once you get to the proper offset, push the FUN key again.

5) Press the FUN key on the Radio and go to Function 01:T-CDC (press the MON key to cycle between OFF, [analog] tone, [analog] tone-edit, [digital] tone N, [digital] tone I and back to OFF again as needed) and use the Up and Down keys to find the proper transmit PL Tone.  

Use the same method to optionally set the proper receive PL Tone, if necessary, on Function 02:R-CDC (or Function 03: RT-CDC if both tones are the same)

6) You can rotate through High, Medium and Low transmit power using FUN and 0 (zero) on the mic.

7) Save to the first open channel by pushing Fun and UP on the microphone (or then use the UP and DN keys on the mic to scroll through the available channels, with empty ones saying NULL

Save to this channel holding down the "MON-*" key on the mic and you are done!
----------------------------------------------------------------

Use DCS Digital Tones:

Go to desired channel
Press FUN on mic
Press 1 on mic
Go to menu 1 using V/M or Main key on mic
Press number 1 on mic to cycle to 000 N display for menu 1
Use up and down on mic to scroll to code corresponding to desired DCS code. 
List is in the instructions.
Use V/M or Main to go to menu item 2. Repeat selection process
Press DIL on mic to exit.

Also Miklor has a tutorial for building a K-1 to RJ-45 adapter to allow the FTDI "baofeng" type K-1 USB cables to work with the DB20-G:

I'm in the call Radioddity camp. Get one connection wrong and you have a bright and shiny new paperweight.

RT Systems has a cable for this radio for $30:

Might wanna buy a programming cable.   Or a good radio and a programming cable.  Can you return the radio still?
