I have the galaxy ssb echo base station. When I power the radio up it is quiet no static and off frequency. I can move the band selector to band b and then back to c then it is on frequency. I have antron 99 coax is new checked all jumpers even took the meters and eagle 200 tube amp out of line and still have the same problem. I did notice the swr is very low when it is off frequency almost flat then I recheck after i get the radio on frequency and swr is normal about 1.2 to 1.3. Do I have bad coax bad antenna any suggestions. I have taken radio to tech and is right on frequency while he has it on bench and hooked to his antenna and coax. Thanks
