First thing I recommend id to run a good ground braid from the powersupply  
to the radio. I have solved several weird problems with this..
good luck

And good filtering.  Old, dried out electrolytic capacitors can have 
lower than rated effective  capacitance, for a while, before they cause a 
more catastrophic  failure.

If it is a filtering problem  due to not enough capacitance in the power 
supply, the peak voltage may  stay the same and the 120 Hz ripple will 
get worse during higher current  loading on transmit. Depending upon what 
kind of voltmeter you use, you  might not see this as much of a voltage 
drop. An oscilloscope would be a  better way to see if this is the 
problem. Or just replace the filter  capacitor(s) and see if the problem 
goes away.
