Content preview: Hello Martin, LF, I'm fascinated by the noise drop on LF which occurs during your sunrise. On your grabber (http://dl.dropbox.com/u/74746618/LF/YV7MAE_LF_Grabber.html ), i can see the noise drops 15 dB within 20 minutes. That means the sun must be very strong so the ionosphere is very quickly ionized. Also the local lightning density must be extreme. All in all it looks like a very sensitive system. But some directivity would be interesting :-) [...] Content analysis details: (-0.7 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- -0.7 RCVD_IN_DNSWL_LOW RBL: Sender listed at http://www.dnswl.org/, low trust [129.206.100.212 listed in list.dnswl.org] -0.0 T_RP_MATCHES_RCVD Envelope sender domain matches handover relay domain X-Scan-Signature: cc2e5baae40f8f7a09b47e6877ef0bfb Subject: LF: 15 dB noise drop in 20 minutes Content-Type: text/plain; charset=ISO-8859-15; format=flowed Content-Transfer-Encoding: 7bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Level: X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false x-aol-global-disposition: G X-AOL-SCOLL-SCORE: 0:2:369559968:93952408 X-AOL-SCOLL-URL_COUNT: 0 x-aol-sid: 3039ac1d604d4fe39f2a6c2f X-AOL-IP: 195.171.43.25 X-AOL-SPF: domain : blacksheep.org SPF : none Hello Martin, LF, I'm fascinated by the noise drop on LF which occurs during your sunrise.
