To check the swr, turn off the amp and whatever else you have between the analyzer and the antenna. Then take your readings. My guess with the Cobra 29 is that the reason your not be able to get the SWR meter to calibrate with the radio is that the deadkey has been set real low: like 1 or 1.5 watts. A lot of SWR meters need 3 watts or so before they will calibrate. At any rate, the analyzer should help you out.
