Content preview: As stated Air/Ground vhf/uhf is AM and simplex working. I have also noticed a well modulated AM transmitter is more potent than a FM transmitter when working at max range. On AM the RX bandwidth can be opened up to receive several stations simultaneously then select the one of interest by closing down the selectivity, the same applies on CW. On FM if you tried this the transmission would fall into a black hole, in other words the FM rx has to be tailored to the exact bandwidth of the transmission (same deviation value) g3kev [...] Content analysis details: (0.8 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- -0.0 RCVD_IN_DNSWL_NONE RBL: Sender listed at http://www.dnswl.org/, no trust [62.24.128.237 listed in list.dnswl.org] 0.0 FSL_XM_419 Old OE version in X-Mailer only seen in 419 spam -0.0 SPF_PASS SPF: sender matches SPF record 0.0 HTML_MESSAGE BODY: HTML included in message 0.0 FSL_UA FSL_UA 0.8 AXB_XMAILER_MIMEOLE_OL_024C2 AXB_XMAILER_MIMEOLE_OL_024C2 X-Scan-Signature: 5f132ffce194fb93f2267a462d849f2b Subject: LF: A/G FREQS Content-Type: multipart/alternative; boundary="----=_NextPart_000_0025_01CD536E.76320530" X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Level: X-Spam-Status: No, hits=0.5 required=5.0 tests=HTML_20_30,HTML_MESSAGE 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: 0:2:408383648:93952408 X-AOL-SCOLL-URL_COUNT: 0 x-aol-sid: 3039ac1d40d84fe966f3567d X-AOL-IP: 195.171.43.25 X-AOL-SPF: domain : blacksheep.org SPF : none This is a multi-part message in MIME format. ------=_NextPart_000_0025_01CD536E.76320530 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable As stated Air/Ground vhf/uhf is AM and simplex working.
