Cathy, I don't know how much your soundcard would load down the speaker line (I would tend to believe not much), but you certainly should not hurt anything, so give it a try.
If you want a separate audio output line for the soundcard, take a look at the K2 Fixed Audio Output article on my website http://w3fpr.qrprqdio.com for some ideas. I do have boards available for $3 each plus 50 cents shipping, sorry, but I am out of the kits and do not plan to re-order. 73, Don W3FPR > -----Original Message----- > > With my Alinco DX-70TH, I have become used to using the waterfall > spectrum display to zero-beat CW signals.
