Radio shows SWR HI When you key the microphone to transmit

Question

SR-655HPC / SR-955HPC that beeps when you try to transmit. It does show SWR HI on the meter when this happens. I have changed the antenna, and the radio does the same thing.

Solution

• The SWR meter that is on the front of the radio is very accurate and can be trusted.
•  It sounds like you have something wrong with your antenna system (antenna, coax, mount). It could be bad connections or corrosion on the mount, which causes poor grounding.
• When setting your SWR, you might need to turn the TSR function off (located in the Function Menu). With it on, it will stop the radio from transmitting with a high SWR. While usually a good thing, but it makes it difficult to set your SWR.

Common factors that cause high SWR readings

• After you complete the tuning process, we recommend turning the function back on.
