I'm a new ham and have only used 2m/70cm so far. I have recently completed a QRP CW setup: a YouKits HB-1B transceiver and a simple wire dipole. I haven't made any contacts yet, and I'm wodering if the radio is even working. A SWR meter shows power to the antenna when keying, but an HF radio nearby is only registering clicks. My question is twofold: how far away would a HF-SW radio have to be from the transmitting antenna to hear a clear groundwave CW signal on 40m, and is there a better way for me to test my rig if I still haven't made any contacts?
