If all of the radios are acting in a like fashion; I would stop transmitting until the fault is found. Most likely, it sounds like a bad cable or imperfect connection on the antenna or a coax connector. Are you still hearing local stations/friends? Or are they intermittant?

If the radio sees a 'no load' situation - all of the output power from the final output transistors will be reflected back into them - and subsequent failure can be imminent. I say this because if ALL of the radios are seeing intermittant SWR readings; then there MUST be an open or short somewhere between the radio and antenna. Including the coax and connectors. The wind may have opened up a connection somewhere - so be careful. Even a cheap radio can cost more $$$ to fix than they are worth...
