Think of it like an engine. You would do better if you connected the outside rail U power to COM and A connected to power on the SC-2. Then you can string a wire connected to the GND connected to your house GND wire. The GND wire is also accessible at pin #5 of the DB9 connector on your Legacy Base.
The reason you got it to work wasn’t because of the hand held CAB2 when you went under the table, it was most likely because you were picking up the signal in the air from the house GND wire with your body and transmitting it close to the SC-2. You were in effect, a GND wire close to the SC-2.

Chuck,
My power is currently coming from the track since I am using all 6 of the connection blocks on the SC-2 to operate 022 switches. Do I need to power the SC-2 directly to the 2 terminals on the SC-2? Do you have a picture or diagram showing the house ground connection point (from receptacle to track) and how the wire should route to the track? If you have a diagram of the DB9 pin #5 connection process that would be helpful.
RF signal in the air gets from the base to the house GND wiring in the walls of the house by the connection of the GND pin on the power supply plug. The U connector on the Legacy Base is the outside rail component of the RF signal. I think that with your 022 switch connected to the 1st section of the SC-2 supplies that U connection to the SC-2. So that leaves the GND wire to be strung over the SC-2. You can get that from the DB9 connector on the Base or from the GND pin on the Base power supply plug or the screw on the wall outlet cover in the house wiring. I made a GND connection by connecting only the third pin, the GND pin, of an AC plug to a single wire and plugging the plug into the outlet. I then had the single wire to drape over where ever I wanted it.
Looking at the DB9 on the Base, pin #5 is the LEFT most pin on the bottom row of 5 pins. It’s probably easier to connect to with a mating male DB9 plug and solder the wire to #5 on the plug if you go that way.

I understand now what to do. I will report back either way as I work on this tomorrow. Thank you very much!

Thank you for sending me in the right direction!
UPDATE
The added GND wire solved my SC-2 problems.
Super, thanks for the update.
