I have one BEL GE524 TRx modified for 20 and 40M operation. at present it is not working. I have found 2 wires got disconnected from the EXT. Channel switch. Colours are brown with blue stripe. One of them is giving 9 VDC and another 0VDC. where to connect these 2 wires? Can you tell me the operating procedure for this TRX? I have not used it for long and cannot remember various settings of the switches. I also have a DDS VFO which I want to connect with this rig. How to connect it and how will it be operated after connecting DDS VFO?
