Another good test of this is a QRP group operating event. It is normally very difficult to place two QRP
transmitters on the air at the same time in the same band. Two such stations should be widely separated,
at the very least several hundred feet, to keep from damaging each others front end. However, under
such conditions, most receivers will overload and distort when the other transmitter is keyed. The
NC2030 has a very stout receiver and handles this situation much better than other radios. The only
drawback is that the two operators will be able to hear the VFO of the NC2030 as this is a DC receiver.
The LO leakage out the front end has been measured to be -50 dbm (0.00000001 watts). This is not all
bad it will not work to have the two transceivers only 500 Hz apart anyway.
Thirdly, listen to the received signal itself. Chirps and key clicks can be heard much more clearly on the
NC2030 than on the typical superhet. Crisp, clean audio is a hallmark of a DC receiver.
Lastly, listen to the band when it is really noisy. The lack of ringing of the NC2030 will make this
awful condition much easier to listen to than on a typical superhet and its ringing crystal filters.
