Microsoft saidthat the free upgrade to Windows 11 has begun rolling outto eligible Windows 10 PCs,and PCs that come pre-loadedwith Windows 11 will start tobecome available for purchaseon October 5. A prompt to upgrade to Windows 11 will cometo newer devices first, withall eligible devices to receivetheir updates by next summer.Windows 11 has higher technical requirements than Windows10, which will be deprecated in2025. Microsoft no longer supports Windows 7 or earlier iterations.

VOLUME XLII, NUMBER 10Page 3LONG DELAYED ECHOES BY Armando Delgado, KN4JNIn the past century humanity notonly put radio waves to good usebut also learned a great deal aboutthem. We found that radio wavespropagate by reflection and refraction from ionized layers in the upper atmosphere, and we alsolearned how different frequenciespropagate. We discovered the effect of solar radiation on radiowaves and the changes that occurwith the 11-year cycle of solar activity. We understand a great dealabout radio waves and radiopropagation, but we do not knoweverything.Occasionally, radio propagationdoes unexpected, surprising thingsthat are not easily explained by theestablished theories. Actually,some of these mysterious phenomena currently lack a clear explanation from our knowledge base. Onesuch mystery is long delayed echoes (LDE).Radio echoes are repetitions of atransmitted signal that occurshortly following a transmission.There are many causes for echoesand those vary with the frequencyof the signal. In HF, however, themost common echo is caused bythe signal traveling around theworld and returning to the transmitter. This phenomenon is notedmost often during high solar activity and high MUF’s, particularly onthe higher HF bands, although itcan happen in any frequency. Aradio signal takes 138 milliseconds to go around the world, regardless of frequency.One other well known radio echooccurs during EME transmissionswhen a signal bounced from themoon returns to the transmitter.This Earth-Moon-Earth trip takes2.7 seconds. Thus, to qualify as anLDE an echo needs to occur atlonger intervals than 3 seconds.LDE’s are not a newly recognizedoccurrence. The first report of anLDE happened in 1927 when theNorwegian Jorgen Hals in Oslonoted echoes of transmissionsfrom radio station PCJJ in Eindhoven that transmitted on 9.55 MHz.He noted two echoes, one at ashort period of 1/7 seconds andanother of a longer period of 3seconds. Hals wrote to Professor Carl Stormer who reportedthe findings in the November 3,1928 issue of Nature, a reportthat triggered an internationalinterest in the phenomenon,with many experts trying todetect and explain the occurrence. Stormer himself carriedon research using PCJJ transmissions and detected LDE’s ofvariable time duration rangingfrom 3 seconds to 8 seconds.Others involved in the researchincluded E.V.Appleton, the British researcher who identifiedthe layers of the ionosphere,and who as part of his ionospheric research detected andstudied LDEs.In spite of the many confirmeddetections of LDEs of variabletime durations, scientists tothis day fail to formulate a clearhypothesis of the mechanismfor these events; although likewith any other unexplainedmystery, there are many suggested explanations, rangingfrom the scientific to thepseudo-scientific and to thepreposterous.The predominant scientifictheory is that the radio signal,passing through the ionosphere, goes on to be caught ina magnetospheric duct, whereit travels a distance of manyEarth radii in that extraterrestrial magnetic field created bythe Earth’s own magnetismand that extends for millions ofmiles out into space. Then thesignal returns back to the ionosphere, where it may crossback to Earth or be reflectedback to the magnetosphere forone or more cycles. The radiosignals that may follow thispath are most commonly in the1.8-4.0 MHz range.Another scientific explanationinvolves an ionospheric duct,similar to the tropospheric ductseen in VHF propagation, thattraps the radio signal causing itto make many revolutionsaround the Earth before theduct breaks and allows thesignal to return back down. Thestrongest argument againstthis hypothesis is that to last 3seconds or more the signalwould have to make more than20 revolutions of the Earth andwould degrade in intensity tothe point that it would be inaudible, which does not seem tobe the case with the recordedLDE’s.One other more radical explanation couples the radio waveto a plasma wave in the upperionosphere. This plasma wavethen travels along the Earth’smagnetic field lines. Eventually, the radio wave decouplesand returns down to be heardagain.Plasma clouds originating fromthe sun and interacting withradio signals at a Lagrangianpoint between the Earth andthe moon is another hypothesissomewhat similar to the previous one.Among the preposterous explanations, the prevalent one isthat extra-terrestrials have setun-manned space probes between the Earth and the moonthat reflect our radio signalsback to us in an effort to communicate their presence.Regardless of the lack of adefinite scientific explanation,long delayed echoes remain aninteresting phenomenon.Here is a sample of a recordingby a Norwegian station of anecho delayed 7.5 seconds.W1AW CW PRACTICETRANSMISSIONS7 PM EST Slow CW : 5-15 WPMMon, Wed, Fri7 PM EST Fast CW: 35-10 WPMTue, ThuFREQUENCIES:1.8025, 3.5815, 7.0475,14.0475, 18.0975, 21.0675,28.0675, 50.350, 147.555Editor’s Note:Send comments about theNewsletter or to contribute information or articles to the Editor’semail address:olardelga@aol.com.
