My first station as a Novice was an HR-10, DX-60, a handful of crystals, resonate wire antennas, and a homebrew beam. Those were the days. Fast forward to 2011 when I returned to the hobby. I purchased a SB-102 and after a friend and fellow Ham restored it my love for tube radios was rekindled.

I tested the CW bandwidth on the narrowest setting of the filter: -3dB at 595 and 660 Hz, -3dB bandwidth of 65 Hz. -6dB at 587 and 660 Hz, -6dB bandwidth of 81 Hz.
