[arm-allstar] Alinco DB9

[Larry]

I have here (2) 435T Mk III Alinco radios. One just arrived new from HRO 
and another older one approximately 4 yrs old.
So my question is not unique to just a new vs old version.

On the rear female DB9 connector are the standoffs for restraining the 
male connecting DB9 cable.
Both radios will not allow DB9 cable screws to mate with the radio 
standoff nuts provided on the Alinco Radio.

It appears that Alinco uses a non standard thread in their standoff. The 
thread is much finer than any PC related DB9 Cable.
Would anyone happen to know the thread size needed to screw into those 
restraining nuts.?
