Duane, I am "blessed" with many old, "boatanchor" receivers, and I just use one of them with the antenna terminals shorted and the RF gain turned down to listen to myself. Perhaps you could find some
Duane, An older receiver can be a good piece of test equipment if you have the room for it. The Drake 2B would be an excellent receiver to use to check your CW note if it has a crystal to cover the 3
