The TED was an AM transmitter with a frequency range of 225 to 400 Mhz. We used them for intership communications. I can't remember their URT designation although I think it may have been AN/URT-7 ... it was almost fifty years ago in my days with the Royal Canadian Navy. Tubes, of course, and the PA's were a pair of 4CX150's Irv VE6BP -- -------------------------------------- Diagnosed Type II Diabetes March 5 2001 Beating it with diet and exercise! 297/215/210 (to be revised lower) 58"/43"(!)/44" (already lower too!) -------------------------------------- Visit my HomePage at http://members.shaw.ca/finkirv/ Visit my very special website at http://members.shaw.ca/finkirv4/ Visit my CFSRS/CFIOG ONLINE OLDTIMERS website at http://members.shaw.ca/finkirv5/ -------------------- Irv Finkleman, Grampa/Ex-Navy/Old Fart/Ham Radio VE6BP Calgary, Alberta, Canada |

I taught them both in the UHF course at Treasure Island (USN ET A School). They were replaced by the AN/SRC-20-21 a channelized monstrosity with a bajillion doublers and triplers in chains to build up the frequency that was dialed in. The TED/RED offered a hands-on appreciation of the physics of wavelength and component size. Part of a filter consisted of a simple post located in a hollow (stub in a resonant cavity with linkage through openings). 73's Richard Clark, KB7QHC |

The site below was from an early Canadian destroyer HMCS Haida which has now become a museum. The site gives a tour of the various radio offices and includes the TEDs and the URR-35 receivers which were paired with them. http://www3.sympatico.ca/hrc/haida/radio/rrintro.htm -- -------------------------------------- Diagnosed Type II Diabetes March 5 2001 Beating it with diet and exercise! 297/215/210 (to be revised lower) 58"/43"(!)/44" (already lower too!) -------------------------------------- Visit my HomePage at http://members.shaw.ca/finkirv/ Visit my very special website at http://members.shaw.ca/finkirv4/ Visit my CFSRS/CFIOG ONLINE OLDTIMERS website at http://members.shaw.ca/finkirv5/ -------------------- Irv Finkleman, Grampa/Ex-Navy/Old Fart/Ham Radio VE6BP Calgary, Alberta, Canada |
