Hint: Cellular telephony had not the impact on electronics design a decade and a half ago. "Phase noise" wasn't talked about much back then. Some MUST have their buzzwords to sound "grown-up" in hum raddio... :-) Hint: It must appear that way to a fellow who spent his time reading only about cellular telephony. The term "phase noise" was commonly discussed "back then" as regards synthesized HF transceivers. Many of we grownups where discussing it two decades back. There were contests a decade ago and farther back. Those that don't have much to communicate can always have "contests" to prove they are "somebody" through point scores. :-) That you see no value in competitive endeavers doesn't really effect those of us who do. How are you effected by amateur radio contests? Especially good point scores through the efforts of "reducing phase noise." :-) I guess it is the little smiley which really makes you sound like a person uninformed on the issue. How is it possible for you to have been a PROFESSIONAL in radio, a PROFESSIONAL in the design of synthesizer circuits and to have been unaware of the problem of phase noise with such circuits? All that's needed is for him to obtain a valid amateur radio license, and an amateur radio station. Why are you so focussed on all MUST have a ham license to discuss anything in here? You've discussed. You just have no experience in amateur radio, no stake in amateur radio and no credibility in amateur radio. You needn't have an amateur radio license at all. Does that clear things up for you? More tsk. My choice of residence location is NOT primarily motivated by any slavering desire to erect a radio station of any kind. Great. It looks like you've got your wish. My Cincinnati home was somewhat motivated by a desire for a good radio location. My present home was selected in large part by a desire for a great radio location with few neighbors. In addition, I have dark skies, a view to die for and quiet which city and suburban dwellers don't even notice they don't have. Residences are HOMES, a place of living. Residences mean many things to many owners. My living here includes amateur radio, guitars, computers, astronomy, reading, writing, photography, videography. I have neighbors who do none of those things. Their residences are for what they enjoy doing in their manner of living. I've lived ON a huge radio station long ago, one much bigger than is possible in any residential area. Not my idea of living for the rest of my life...but important back then. If you want to live ON or IN a radio station, feel free to apply for a broadcasting license and make sure the local ordinances allow living on business premises. I currently live in the midst of a goodly sized radio station. I didn't need to apply for a broadcasting license. I have no business on the site and it wouldn't matter anyway. This county has very few restrictions or zoning laws. For a small part of my life the radio station complex was built ON an old airfield. Not even the old Press Wireless station in Palos Verdes, CA, (the one bought by a ham) was that large. ....but one man, Don Wallace W6AM bought that 25 acre Press Wireless site, complete with rhombics and the large building which formerly housed the station. He used it primarily for DXing and contests. End result is "can't fix it because the parts cannot be had". It is probably easier to restore a 40 year old R-390A or 75S3 than a 20 year old R-70, if certain parts are needed. BWAHAHAHAHAHAHHAHAHAHA!!!! Riiiiight. Try to find a replacement for an R-390 power transformer... or anything inside that PTO...even in 1980... :-) There are, in fact, numerous sources for such parts. Last vacuum tube receiver I DESIGNED and built was in 1964-1965. HF. Wasn't for listening to on-off keyed radiotelegraphy! [horrors!] Terrible thing! NOT A LICENSED AMATEUR DESIGNING AND BUILDING AN HF RADIO! Call out the radio police! No license was or is required to build a receiver. In fact, no license was or is required to build an amateur radio transmitter. You'll need one if you want to hook it to an antenna and transmit though. It didn't use any "recycled parts." A pity that you had nothing useable on hand. Dave K8MN |
