Re: LF: Jason 0.94 tests

["Dick Rollema" <d.w.rollema@freeler.nl>]

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.
