    Very nice. But that radio is too modern/crowded for my liking. I prefer my Corsair II for tinkering.


    For those who don't know, you can measure the bandwidth of the demodulated signal with the help of a sound card and some free software:

    There is stuff for Android as well, in those cases you can even use the phone's microphone to make the spectral analysis.

    You ain't seen "crowded" yet!

    The next part of this project details construction and installation of dual roofing filters and the switching assembly used to activate them. Of course, as luck would have it I found a YK-88A1 on FleaBay the day after I posted the DIY AM Filter mod...
