Exactly what he said...  Do the other towers stay right on normal?  

If it is a feed problem, almost 100% of the time, the other tower/system readings will change by some amount (or even knock the TX off due to VSWR).  This includes the common point current, TX VSWR, etc.

If the affected tower isn't the Reference tower AND only one tower's readings is changing while every other parameter stays normal, it is almost certainly a sample problem.  IE, Twr1, Twr2, Twr4, CP, TX VSWR, TX PO readings all remain within normal constraints, it is typically a sample problem.

And sometimes not...

Do you have sample loops or toroids?

Absolutely don't crank anything until you know what is causing the original problem.

Is only tower 3 affected?  My experience has been is the operating parameters are actually changing on one tower i has an effect on the other towers' parameters too. May have an issue with your sample system.
