What causes the transmitter to come on the air? Is the signal that makes that happen available to the outside of the Ultimate 3?
wanted to listen and report to wspr with another receiver, but I haveThe MagicBox could switch the antenna for you, so to speak so that when the Ultimate 3 isn't using the antenna, the receiver can be.
Yes, that's exactly what it does, but it needs a signal from the transmitter to tell the MagicBox that the WSPR transmission is going to happen.
The maximum output is 200 mW, but normally I use between
10 -100 mW.No problem there.
So I am looking for some sort of HF sniffer which triggers the magicNo, you need the signal from the Ultimate 3 that causes it to transmit and use that signal to key the MagicBox and cause it to go from receive mode to transmit mode. The MagicBox keys using a voltage being grounded, like closing a key.
