They asked me to test using a dummy load. I ordered one, when it arrived I connected to the meter and radio. 1:1 SWR, still around 35-37 watts when using high power on GMRS 16-22. Using a Surecom SWR/Power meter. I believe I have a defective radio. I purchased this one because of the advertised 50 watts compared to Midland and BTECH radios. Not happy so far.
