Hi 307, I have done the freq. and clarifier mods on my TR696F-SSB but would like to know how to do the 10 KHZ jump switch mod.I can use an external switch like I did for the channels or the NB switch on the front panel.I just need to know what to hook the wires to. I am familiar with the method used for the EPT 6000 10z board but can't find the same jumpers on this one. Thanks,Starlighter |

Galaxy DX Radios DX959 Documentation Project 10kc Mod Changing the logic level of pin 16 on the RCI 8719 PLL chip will give you a +10kc or -10kc depending on channel selector. Cut the trace at pin 16 as shown and bridge the cut with a 4.7K ohm resistor. You can then wire the center contact of a spdt on-off-on switch to the PLL pin side of the 4.7K resistor Pin16. Wire one outside contact of the switch to Pin 9 for 8 volts and the other outside contact to Pin 18 for board ground. |
