Topband: cutting coax stubs for 80 meter 4-square

[Wes Stewart]

Maybe my "Zoom" model is different from yours but I opened up my AA-55 Zoom and 
found the connector to be rather securely mounted.  So much so that I 
reconsidered my idea of replacing the SO239 with a type N.  Not that it isn't 
doable, just that it was more trouble than I wanted to bother with at the time.
