Has anyone posted measurements or simulations of the four SRL+XV8.3 band-pass filters? This was asked and seemingly unanswered by Bill AB3DT in message no. 21521.
I've just checked docs in: Files > Lite+Xtall v8.3; nope. I don't want to re-invent the wheel. But if this data isn't available then I'll go ahead and simulate in LT-Spice. Are there any measurements or suggestions on what to use for the coupling factors between the primary and secondaries of the input transformers? The reason I'm asking is I'm planning to control the Si570 externally, and I would like to see what can be covered outside the Ham bands, perhaps part of some abutting SW broadcast bands. Sometimes when not in QSO it is nice to listen to the news or perhaps use WWV etc. to check frequency. 73's, David WB4ONA
