[amsat-bb] IC-910H Transceiver Question

[WB2LLP]

For many years I have used this Transceiver intermittently as a receiver in a protected location, so I never got around to grounding it.  Now I am not in a protected location and want to transmit,  so the Transceiver  must be grounded.   I  check the manual  on page 14.  Yes, there is an empty, threaded  location on the back panel for  the ground connection,  but it does not say what thread the connection has. Now this normally would not be a big deal, as I would go to my bucket of nuts and bolts and get a few bolts and find which one had the correct thread.   Unfortunately, I am not  near my normal location and the junk box so  I look more carefully at the manual for  the thread size and do not find the information.

If someone reading this knows the thread size I would appreciate it if you would let me know, so I can go get one,
maybe two so I will have a spare,  and then mark up my manual.
