When you key up without talking, you put a very small amount of RF out and get some reflected power back. The response of the Rorward and Reverse detectors in the SWR circuitry and the granularity of the analog to digital conversion in the metering circuitry and firmware must combine to give you this "funny indication", which goes away as soon as you talk and give the radio enough RF to work the metering properly. NOT A PROBLEM, just a limitation of the design in an anomolous situation. Hope this helps. 73 Om de W1AEL, Allan.
