Well, this my Dexicon rated at 220VAC 15Amps RFI/EMI Filter on my input of my
TL-922A, works well !

Have you tried an Input AC Line EMI Filter on the Amplifier
Assume you using 220VAC
Use a Dexicon LC2KVA for 220VAC at 10amps ( Surge, Transient and EMI Filter
with SoftStart & Noise Reduction Feature )
here is a 220V 20Amp rate device below

Some other I have seen for 220VAC at 50Amps on Ebay from 50Kw TV stations by
Tokin to eliminate EMI are available as well !

Let me guess, you are using an Off Center fed dipole, or some sort of
asymmetrical antenna If not what is your transmit setup.
