The primary intent was to test QRPp on LF. Listening and decoding were Jay (W1VD - 304 mile / 487 km path) and Garry (K3SIW - 662 mile / 1059 km path). Both Jay and Garry reported multiple decodes over the several days at QRPp power levels ranging between 0 dBm to -13 dBm ERP. Examples include: W1VD - Regular decodes at -13 dBm (50 uW) ERP including 3 at mid-afternoon. Typical: Rank 0 car EB/N0 9.6 EB/N0 8.5 -13 DBMERP_LF K3SIW - Regular decodes at 0 dBm (1 mW) ERP. Typical: Rank 0 car Eb/N0 6.5 Eb/N0 4.0 0_DBM_ERP_LF! This brief experiment demonstrates QRPp possibilities on LF and highlights the capabilities of EbNaut as a weak signal mode. Further experimentation welcome. 73, Rob - K3RWR FM18qi
