The signal overnight 11th/12th reached about 0.085 fT, the best signal strength so far. Was that due to the increased ERP or propagation. The noise was high that night too. Overnight 12th/13th I cannot see the signal in my usual 6 hour integration. A bit of a spike at 8270.008435 but that's not a frequency your divider would allow. I've been looking at the signal at Forest. The peak is visible on the first two nights but not since (or before). It is also visible in the raw recording at the receiver site. But the frequency is different. After a careful look at it, the spectrum is peaking at close to 8270.007 + 20 uHz, on both nights. This doesn't agree with the frequency measured at Todmorden, which started out around +46 uHz and settled by the next night at +93 uHz. Because of this frequency offset, we must for now discount the detection at Forest. Hopefully we will get it back with a boost to ERP. -- Paul Nicholson --
