|This has to be one of the simplest adaptions you could do. This radio is programmed to have 10 blocks of 40 channels which include the UK40, Splits and -11ch dropper. All you need to do is remove the case and make sure the power is completely disconnected from the radio, then with a hot soldering iron and desoldering pump remove a solder link. Thats It !! How easy is that.... leave the radio for 5 mins then connect up the power and you will be away.
This works on the Cobra UK25 LTD ST and UK29 LTD ST. On the 29 the blocks are controlled by the tone and delta tune controls, on the 25 I believe it to be the tone and the dimmer.
They say a picture is worth a thousand words so see below where the solder link is... click for a larger view...
