New On This Site

     January 28, 2010 - Because the RF Specialties web site has vanished I have added a download of their RFS Technical Programs.

     October 27, 2009 - I've revised my Microsoft Excel files for documenting 66M and 66B punch blocks.   Each now has two sheets, for blocks with and without trunks.   The sheets for blocks with trunks have the standard Belden mult color codes in the first color column.

     March 6, 2009 - Since the late 1980s I have used Sunout to predict satellite solar outages. It is an MS-DOS program that can predict the entire span of outages for a satellite in a season, with estimates of severity, the overall daily outage window, and the daily window of maximum severity. It does not come with satellite data, so the user has to provide that. It can handle only whole degrees of satellite spacing, so if you have a sat at half-degree spacing you will have to set up two pseudo-sats at the whole degrees on either side and interpolate the results.

     July 20, 2008 - You can download the VRC 2000 hardware manual, the VRCWin software, the VRCWin manual and the MS-DOS SetupVRC software with instructions.

     May 27, 2008 - Michael Barnes has shared his photos of the 22-May-2008 Salem Radio Network UPS Room Burnup.

     April 3, 2008 - I've posted a 1024x768 bitmap image of the WBZ towers past and present. On the left are the original WBZ (later WBZA) towers atop the old Westinghouse factory in East Springfield. That site is slated for imminent destruction. On the right are the current WBZ towers in Hull.

     June 15, 2004 - The earlier database file used for programming the Sine Systems RFC-1 and RFC-1B has been replaced by a new Microsoft Excel version.

     June 9, 2004 - For the members of the CRTech mailing list I have posted a PDF file containing the affidavit in support of applications for search and arrest warrants in the 1993 case of the Roanoke Phantom.  Note that this is a large file (5.44 Meg) and that one section contains examples of the indecent language sometimes used on aircraft frequencies by the Phantom.

     September 6, 2003 - Follow a vintage Gates BC-1G transmitter on moving day.
