Hi, I am qrv on WSPR not on a regular base but rather occasionaly. Yesterday when I worked on various HF bands, I found that radio propagation on the higher HF bands (21MHz and up) was excellent. So I decided to put WSPR back on the air once I finished qso-ing on 10m. I found that 21 MHz produced a few spots, where as 24,8 and 28 none. I may have to check the accuracy of my dial setting (calibration) on my Electaft K2 for the higher HF bands. 18MHz and 14MHz work fine! Have fun on WSPR everybody!! DL2GAN (using +33dBm, 2W on a 7m (21ft) vertical).
