Hello, I restoring a complete FT-101 station from parts acquired from eBay piece by piece (yes, it is a nightmare). My latest issue is trying to get my FV-101B external VFO to work with my home made cable. At first I just matched pin to pin on all 8 pins and this seems to work with the YC-601 digital display. My homemade cable works when connected to the digital display and the frequencies are accurately reflected, however when I instead plug in the external VFO all that happens is the bulb in the unit lights up. When I select the external VFO on the FT-101 all that happens is I lose audio and the internal VFO no longer works. The external VFO seems to not function at all. Does anyone have experience with making these cables? I would love some input on this as I have no idea if it's my cable or my FV-101B unit that is bad. Thanks for any help you can give!
