Towers are still pained red and white for visibility. The colour scheme seems sensible but in the UK I have never seen RED and WHITE masts. They are GREY regardless of height ie Rugby and Droitwich and others. The old 300 ft radar masts on the South coast were just plain wood colour. de mal/g3kev There has never been any LF broadcasting in the US. There is a big Blaw-Knox tower in Nashville, Tennessee for station WSM (650kHz) and a smaller one in Manchester, NH. The Manchester NH Blaw-Knox tower has been used by hams after hours on 160 meters. There are just as many high power MW stations and big towers in the US as before, but now it is common for formerly daytime only stations to have reduced power at night which creates QRM for MW dxers. -- 73 Warren K2ORS WD2XGJ WD2XSH/23 WE2XEB/2 WE2XGR/1 On Fri, Oct 2, 2009 at 11:21 AM, mal hamilton wrote: > I have seen some similar type antennas while flying across the USA years > ago > painted RED and WHITE if I remember correctly. > That was in the days when LF and MF were the norm for broadcasting, before > the advent of FM and satellites, although there is still plenty of LF/MF > broadcasting but mainly low power local stations these days, and antenna > masts are more modest structures than they used to be. > de mal/g3kev > > ----- Original Message ----- From: "Clemens Paul" > To: > Sent: Friday, October 02, 2009 4:03 PM > Subject: LF: Re: Circa 1930s 545 kc in Budapest > > >> How about that? >> http://www.waniewski.de/id414.htm >> >> HTH >> 73 >> Clemens >> DL4RAJ >> >> ----- Original Message ----- From: "Dexter McIntyre W4DEX" >> >> To: >> Sent: Friday, October 02, 2009 4:29 PM >> Subject: LF: Circa 1930s 545 kc in Budapest >> >> >>> I have a 1936 edition of Electrical Engineers Handbook by Pender - >>> McIlwain >>> which show a diagram of a 1030 foot antenna in Budapest used on 545 kc. >>> So far >>> I have found no history on this antenna.
