I realize that the 2020 is not Yaesu but thought someone out there might be
able to help. I need the power cord connector for the 2020. As it is a
special connector, I really didn't know where to get one. If you have
either an A/C or DC version that I could buy, let me know. If you know a
source of the connector(female) let me know also. Any help would be
greatly appreciated.

I had the same problem and was unable to find the power cord. I did have the power connector pinnout for both ac and dc operation as I obtained from Henry Radio if you want a copy of it give me your e-mail address and I will send you my file showing this. I went ahead and rewired it making my own cord by eliminating the 16 pin connector but now wish I had not done so and may undo all my work because in my search finally found some connector pins that perfectly fit on the connector on the unit and it would make it very easy to make a power cord with jumpers. The company I ordered the pins from sent me 500 of them....so I can send you 16 of the pins if you would like to make your own cord using them and the pinout diagram.
