I have noticed that my tx power varies depending upon where I am in the passband. As my radio most likely uses the same crystal filter for tx ssb generation as it does for RX filtering then one can in a way map the response of the filter. My radio is an Alinco DX-77, and I get maximum output at about 1800 Hz. Having mapped my filter on TX, I suspect that my filter response is not the steep sided flat-topped filter response as described in books, but rather is more of a bell shape.
Has anyone else noticed a variation in power output across the waterfall? 73 de Brett -- =============== Brett Rees VK2TMG http://lisp.homeunix.net [Non-text portions of this message have been removed] Need a Digital mode QSO?
