Power Supply
One of the best places to tap +5V from a Pro-2035/2042 is IC-8. IC-8 is just a 7805, 780L5 or a chip of similar flavor, which is a +5V voltage regulator. If you take off the top cover, you will see two chips in the area behind the volume and squelch knobs. They sort of 'hang' off of the PCB (printed circuit board) and are bolted to the chassis for heat sinking. You should see '7805', '78L05' or something similar printed on the chip or you can see IC-8 silkscreened on the PCB. There also should
be the word 'OUT' or 'OUTPUT' silkscreened near one of the pins. This will be the pin with regulated +5V. I usually solder a solder-tail to this and insert a wire (24 ga.) into it.

Programming Sequence and Duplicate Entries
There is a little problem that the PROgramit has with the Pro-2042 that is not evident in the Pro-2035. It deals with duplicate frequencies. I sometimes have a freq (i.e. 39.54 Mhz) in more than one bank. The 2042 will not allow this with the normal programming steps of the PROgramit. It also throws a fit when you start programming and you haven't cleared out some of the freqs that you are programming again. The solution to that is to place ENTER into the programming sequence twice. If it is a 'dupe' freq it will go ahead and program it in and if it is not a 'dupe' then it will ignore the second ENTER.
