Using 3 different pieces of test equipment to measure the RF output power, together with a precision dummy load VSWR <1.02, I am unable to get more than 44W out at a requested level of 50W. WMTR setting is flat out at 30. At 120W I get 106W out.
Raised this with Support and Wayne and they are looking into it. Also the gain calibration routine in the manual is very sparse and confusing. 73 Stewart G3RXQ On Sun, 16 Mar 2008 10:45:14 -0400, Mike Penkas wrote: > Same here with the wattmeter calibration.
