Advances in communications in recent years have come at a startling pace. In the old days, tocommunicate via radio one needed a good antenna, a selective receiver, and a powerful transmitter.While those items are still useful, today there is one more item required: good software. The “weaksignal propagation reporter” software or WSPR (pronounced “whisper”) is one such advancedmethodology....
Today I was running WSPR on 20 meter band with my tuned (by YAESU FC40) End Fed 9m long Wire. The results are not bad at all. Wake Island (KH9) in Pacific (WA2YUN) with 5 /50/100 Watts (Average distance = 11977 km), and all Europe including the "dark" 20m zone to OE3KFB (Austria). Also contacted with OX3XR Greenland. Conditions were stable on 14 MHz. from 10 to 15 GMT. The 'tube' to North America...
Just installed the WSPR application on My SONY VAIO Notebook under OS Windows XP SP3.
Working stable. Amazing that my QRP 5 Watts and simple Vertical Antenna is enough for contact with Australia and USA on 40m (!).
This Application is useful for HF and VHF conditions analise.
