Simple Ham Radio Antennas--What in the world is WSPR? (PART 1). Post #428.


Now that the FCC will soon release frequencies in the 2200 and 630 meter bands for Amateur Radio use, interest in these bands is growing, especially among members of the QRP (low-power) community. Because antennas for these bands are so large, hams are resorting to many digital modes to enhance whatever antennas they can create for these bands. For example, a half-wave dipole for 472 kHz to 479 kHz will exceed 991.ft/302.29 meters. This is where weak signal digital modes such as WSPR come in. This simple video from "Calgary Toad" serves as a short tutorial on WSPR or the Weak Signal Network. WSPR, designed for the QRP enthusiast, sends FSK transmissions and lets the operator see instant propagation reports. This video is part 1 of a 2-part series on the WSPR digital mode.
