When I transmit the CH Display shows 00 and 2.1. What is my radio showing?

• The SR-447HPC2 displays your SWR when you transmit. While it's measuring your SWR, it will show 00, and then 2.1 is your SWR. If your SWR gets too high, it will show E4 when you try to transmit. The high SWR feature prevents you from transmitting and damaging your radio.

Why do you have a high SWR?
