Hi Roman. My current TX produces 100 Watts, and the calculated efficiency of the antenna is abt 0.6%: 0.255 Ohm radiation resistance calculated with MMANA-GAL and a measured total antenna system impe

Hmm I just found an email (to this group) from Andy G4JNT, dated 17 jan 2013. w.r.t the AD9850 and WSPR-15 he writes the following: Incidently, the low cost AD9850 DDS modules with their 125MHz clock

TKS Minto! SWLing 136 khz today for a while. RA3TTS start Op32 at first today after QRT. I hope to see some activity on 472-479 in WSPR-15 and Op8 some later. Roman RW3ADB. Thu Feb 07 2013 01:54:08 G
