Hello, I have an old TS530 that suddenly started having a transmit problem. My received audio is garbled and not very intelegable. This problem ocured suddenly. One contact was okay, the next reported this audio problem.
The tune up seems ok and tunes okay with the dummy load showing SWR of 1:1. When turned to an antenna there is higher SWR than before. When the antenna tunner is used to tune the antenna I am unable to bring down to acceptable SWR, down to perhaps 3-5 at best.
When I then bring another rig into use (TS-430)I am able to tune to 1:1 with no problem.
Any ideas. Finals?
