PSK Reporter Can be setup to show the stations that are receiving you. DX Maps

6 meter opening to Europe last Summer, but what is important is where it is open from and to. Operating Hints

When using a computer sound card, turn off computer sounds Also turn off any voice announcements Remove the mic from your rig if using aux audio inputs. Most rig dont mute the mic when using the aux input.

Use the rig monitor to check your audio for hum and RF. Check the DT, delta time, should be .5 seconds or less. If you use 100 Watts, be sure your radio can handle it for the long operating time. Add extra fans if needed.

Advanced Operating Hints In crowded band conditions or working DX, try using split transmit & receive frequencies. When calling DX try sending the signal report first instead of your call/grid square. When working DX, try calling him split, Either just off his frequency or on the low end of band. Calls are displayed starting at the low end of band. Call 1st will work the first station found when the station

is calling CQ. Listen to the DX station to see the transmit sequence, 1st or 2nd and how they are handling the pile up and if they are working split. Try tail ending, listen when the DX station send 73 and call then. You might try a different frequency or split.

Look for DX stations that are working S&P and call them. If the receiving frequency on the waterfall display is red, this is a strong signal or multiple stations calling and it can be hard to decode. Computer Audio Rig Interface
