Hello Fred We should not make or anticipate any changes above 50 MHz. Any changes to the bands above 50 MHz would be unnecissary. 73, Kermit W9XA Sent from Yahoo Mail for iPhone On Friday, July 19, 2019, 09:19, fred@antennazoning.com <Fred@antennazoning.com> wrote: <!--#yiv8038119325 _filtered #yiv8038119325 {font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;} _filtered #yiv8038119325 {font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;} _filtered #yiv8038119325 {font-family:"BankGothic Md BT";panose-1:2 11 8 7 2 2 3 6 2 4;}#yiv8038119325 #yiv8038119325 p.yiv8038119325MsoNormal, #yiv8038119325 li.yiv8038119325MsoNormal, #yiv8038119325 div.yiv8038119325MsoNormal {margin:0in;margin-bottom:.0001pt;font-size:11.0pt;font-family:"Calibri", "sans-serif";}#yiv8038119325 p.yiv8038119325MsoFootnoteText, #yiv8038119325 li.yiv8038119325MsoFootnoteText, #yiv8038119325 div.yiv8038119325MsoFootnoteText {margin:0in;margin-bottom:.0001pt;font-size:10.0pt;font-family:"Calibri", "sans-serif";}#yiv8038119325 span.yiv8038119325MsoFootnoteReference {vertical-align:super;}#yiv8038119325 a:link, #yiv8038119325 span.yiv8038119325MsoHyperlink {color:blue;text-decoration:underline;}#yiv8038119325 a:visited, #yiv8038119325 span.yiv8038119325MsoHyperlinkFollowed {color:purple;text-decoration:underline;}#yiv8038119325 p.yiv8038119325MsoListParagraph, #yiv8038119325 li.yiv8038119325MsoListParagraph, #yiv8038119325 div.yiv8038119325MsoListParagraph {margin-top:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt;font-size:11.0pt;font-family:"Calibri", "sans-serif";}#yiv8038119325 span.yiv8038119325FootnoteTextChar {font-family:"Calibri", "sans-serif";}#yiv8038119325 span.yiv8038119325FootnoteTextChar1 {}#yiv8038119325 span.yiv8038119325EmailStyle22 {font-family:"Calibri", "sans-serif";color:windowtext;font-weight:normal;font-style:normal;}#yiv8038119325 span.yiv8038119325EmailStyle23 {font-family:"Calibri", "sans-serif";color:#1F497D;}#yiv8038119325 span.yiv8038119325EmailStyle24 {font-family:"Calibri", "sans-serif";color:#1F497D;}#yiv8038119325 .yiv8038119325MsoChpDefault {font-size:10.0pt;}#yiv8038119325 _filtered #yiv8038119325 {} _filtered #yiv8038119325 {margin:1.0in 1.0in 1.0in 1.0in;}#yiv8038119325 div.yiv8038119325WordSection1 {}#yiv8038119325 _filtered #yiv8038119325 {} _filtered #yiv8038119325 {font-family:Symbol;} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {} _filtered #yiv8038119325 {}#yiv8038119325 ol {margin-bottom:0in;}#yiv8038119325 ul {margin-bottom:0in;}--> This is Version 3, it adds a UHF/microwave thought. In addition, it suggests adoption of the compromise band plan that both sides agreed to in passing but, for failure of a complete deal, was never adopted. As of [FH:] Friday morning, I favor: · Drop the 300 baud limit, · Adopt 500 Hz for digital as the max bandwidth outside of the ACDS band, · Adopt 2.4 KHz within the ACDS band, · Limit ACDS stations to the ACDS band, · [FH:] Above 900 MHz, no bandwidth limitations for digital communications. · Require Listen Before Transmit, · Retain the Rolf, AB1PH, rule: By its language in the Rolph Order, RM-11699[1], the FCC concluded that Rolph provided no demonstration that either existing Amateur Radio or available dedicated public safety communications channels were incapable of dealing with emergency communications requirements. But then the Commission stated that “amateur stations must be capable of understanding the communications of other amateur stations.” Rolph Order at para. 6. It concluded that “allow[ing] encryption to obscure the meaning of messages transmitted during emergency services operations and related training exercise would not improve or enhance the operation of amateur service station or otherwise be in the public interest.” Id.
