Content preview: Hi Roman. My current TX produces 100 Watts, and the calculated efficiency of the antenna is abt 0.6%: 0.255 Ohm radiation resistance calculated with MMANA-GAL and a measured total antenna system impedance between 42 and 48 Ohms depending on the weather / water content in the soil. So 0.6 Watt ERP (theoretically) i.e. +28dBm. But actual ERP is certainly (much?) less because of nearby trees etc: -6 dB (Stefan) of possibly even -10 dB (Mal) [...] 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 [74.125.82.50 listed in list.dnswl.org] 0.0 FREEMAIL_FROM Sender email is commonly abused enduser mail provider (minto.witteveen[at]gmail.com) -0.0 SPF_PASS SPF: sender matches SPF record 0.0 T_DKIM_INVALID DKIM-Signature header exists but is not valid X-Scan-Signature: c8ff00257edaad8e124ab9389da9609a Subject: LF: Re: WSPR MF Content-Type: text/plain; format=flowed; charset="utf-8"; reply-type=response Content-Transfer-Encoding: 8bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Level: X-Spam-Status: No, hits=0.1 required=5.0 tests=MISSING_OUTLOOK_NAME 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-AUTHENTICATION: mtain-dc06.r1000.mx.aol.com ; domain : gmail.com DKIM : fail x-aol-sid: 3039ac1d40865112dfd05438 X-AOL-IP: 195.171.43.25 X-AOL-SPF: domain : blacksheep.org SPF : none Hi Roman.
