About RF Cafe
Copyright: 1996 - 2024 BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Over the past many decades, my involvement in stamp collecting (philately) has waned and ebbed with the amount of time available to dedicate to it. Commemorative stamps - from all countries - have always been of the greatest interest to me. Even if you are not a philatelist, your interest in radio should be piqued by the large number of postage stamps that have been issued in radio's honor. Although I do not own most of the stamps pictured here, there are some that are in my collection. This is a small cross-section of what is available. Over time, I have added to the list and will continue to do so. Please let me know if you have relevant stamps to add. I was amazed to discover how many countries have postage stamps recognizing the important role that weather radar has played in history. Update 1/30/2017: Mr. Neil Carleton contacted me with information on his very fine, very extensive collection of radio-themed postage and special-purpose stamps. They are going to auction in May. Note: Many of these images are uncredited because although I might have retrieved them from a particular website, they appear to be replicated in many places. Therefore, the true origin is not known. My policy is to always provide attribution as part of the "Fair Use" law when the source is certain. I will be glad to link back to the owner's website if evidence of ownership is provided.
A more comprehensive list can be found on the Ground-Based Remote Sensing in Meteorology (Radar, lidar, sodar, etc.) website from Cooperative Institute for Research in the Atmosphere (CIRA) at Colorado State University. This website has a few other communications Postage Stamps. Yet another source is Joseph Morris' Flickr collection. |
