The site is: http://www.olduse.net If you prefer to use your own newsreader, the site also supports an NNTP connection at: nntp.olduse.net:119 From rec.ham-radio Sun Feb 19 09:09:14 2017 Relay-Version: version B 2.10 5/3/83; site utzoo.UUCP Path: utzoo!utgpu!water!watnot!watmath!clyde!cuae2!gatec h!mcnc!philabs!tg!chasefrs!djs From: Newsgroups: misc.wanted,rec.ham-radio,sci.physics,sci.research,sci.misc Subject: Radio Wave Propagation Predictions Message-ID: Date: Wed, 11-Feb-87 16:59:53 EST Article-I.D.: chasefrs.15 Posted: Wed Feb 11 16:59:53 1987 Date-Received: Sat, 14-Feb-87 18:58:49 EST Lines: 36 Keywords: Radio Wave Propagation Predictions Xref: utgpu misc.wanted:519 rec.ham-radio:400 sci.physics:633 sci.research:45 sci.misc:168 I am looking for information about "Radio Wave Propagation Predictions". Any information about any papers, programs, or methods of predicting the signal strength, maximum and minimum useable frequencies would be appreciated. I am looking for the address to obtain : ESSA TECH REP ERL 110-ITS 78 "Predicting Long Term Operational Parameters of HF Skywave Telecommunication Systems." ESSA TECH REP ERL 157-ITS 100 "Short Term Prediction of F2 Layer MUF from local magnetic activity" (1978) Predicting the Performance of HF Sky Wave Telecommunication Systems - Office of Telecommunication Systems Report OTR-76-102 Ionospheric Predictions Vol 1,2,3,4 Office of Telecommunications Research and Engineering Report 13 OTRER 13. (1975) MINIMUF-3 A Simplified HF MUF Prediction Algorithm NOSC TR 186. (Feb 1978) Representation of Diurnal and Geographic Variations of Ionospheric Data by Numeric Methods J RES NBS 66D(4) CCIR Atlas of Ionospheric Characteristics CCIR REP (1960). CCIR Interim Method for estimating Sky Wave Field Strength and Transmission Loss at frequencies between the approximate limits of 2 and 30 MHZ CCIR Rep 252-2 (1970). If you have any of them and can photocopy them I would gladly pay the photocopying cost plus postage.
