It would also to be good to see it there is DC blocking between the
TX and phasor. Some Harris transmitters have this as a part of their
design. You may have an issue of static build up just presenting it
self as VSWR.
I looked after the 2.5 KW version of this TX and it had no such
problem. So it is not the design. .

Be VERY careful modifying the networks on a DA.
This WILL affect bandwidth and such.
Check with your design consultant before doing such mods.
