To Jim and the LF-group.

At 1912 UTC I received M0BMU's signal with 42.5 microvolt over 75 ohm of the SPM-12. If I did my sums right this is -78dBm or
S8 + 1 dB (S9 = -73dBm, S8 = -79dBm).

Jim's field strength came out as
9.8 microvolt/m. Using Reg's groundwave program, pastoral ground (5) and Jim's ERP of 400mW (218mW EMRP) the program predicts a field strength of 9.50 microvolt/m.

I have no means to decode Jason, so only measured the strength of the signal.

Dear LF Group,

No reports received so far from last night's Jason tests - so will try again this evening at the same times - 400mW ERP from 1900 until 2000 utc, and 40mW ERP from 2000 until 2100 utc, on the same frequency 137.500kHz. Any reports welcome - even if you get no copy!

Cheers, Jim Moritz
