I use a Radio Sack DSP box connected to the audio output. With the audio
filtering the ARC-2 is usable on CW. I used mine quite a lot checking in
to the East-Coast Old Military Radio Net CW session. On the other hand,
the ARC-2 is almost useless receiving AM if the band is busy with adjacent
signals.
