A story ran in Stars and Stripes (mil newspaper) 2 or 3 months ago saying that the Wullenweber at Misawa Japan was then being decommissioned and torn down. The sole surviving such site was now at Elmendorf AFB AK. Bob k2euh _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: and KDKA
In recent years many Canadian fulltime AM stations have been shut down on AM and moved over to FM. However they remain notified which is a semitechnical term meaning the Canadian government tells other countries such as the US, which are signatory to treaties, that those facilties still exist. The New Brunswick 700 went off the air several years ago. I think the Alberta is off the air as well. Another source of this kind of information is the AM Pattern Book, published by the National Radio Club. They just published a new edition this year.

Re: Topband: The Quest to save AM radio
Unlikely to ever get past the starting gate as AM Broadcast is a worldwide allocation and I'd think that many other nations have an opinion on this. 73 Bob k2euh Mike Armstrong armst...@aol.com wrote: Brad, *I* say GOOD, let them kill AM broadcast and give the band to US. we will put it to good use he he he he.

Re: Topband: J6
Re: J6/N7QT I worked him around 02z on the 10th on 80 CW and asked about 160 and he said 'probably tomorrow' but I never heard him that night and I stayed home from an event my wife wanted to go to as well to look for him ... ouch He was on 30 m though. I heard somewhere that they had to share an antenna between 80 and 160 and could do only one band at a time. I heard a local op on the 2meter FM repeater who was on previous Buddipole expeditions, who spoke of this one as if it had already finished. This was last night here. J6 would be new on topband here. I had not heard of any of the other J6 'buddipole' ops being on 160. 73 Bob k2euh Carl Jonsson carl.jonss...@gmail.com wrote: Anybody hrd J6 /N7QT on 160?

Re: Topband: Is PT0S still on 160M?
They had been up on 80 cw earlier tonight but QSY to 160 at 10 pm local time, 0300z Wed, on 1825, listening up 2 and with best signal I have hrd them so far (in FL), wkd with 200 w out and 70 foot longwire, after I had thrown down a sketchy radial field. Best around 04 z and was working a mix of EU and NA. Still going at 0520z.

Tom W8JI w...@w8ji.com wrote: Completely agree, but you didn't say how to get past the garden committee. :) 73, Guy. Thin wire or move. When I was in a townhome in Tampa I was able to use what is called paddle wire. This is 22 ga. steel wire painted in green enamel. It is used in crafts work for tying up plant stems for floral decorative work and is sold e.g. in the crafts dept in Walmart or Michaels etc. For antenna work it can't be easily soldered, is subject to kinking and may develop rust spots and probably can't well handle QRO. But, when run through trees is really hard to see. I used it as an end fed random wire for a good while on HF and it was the difference between being on-air or not. Being steel it is pretty strong. It is sold in bobbins that have to be unwound and straightened. ..just a suggestion. 73 Bob k2euh ___ UR RST IS ... ... ..9 QSB QSB - hw? BK
Topband: LF magazine -was- Re: Skywave for LF
There is a printed monthly magazine called Lowdown published by the Longwave Club of America, running typically 24 pages, covering everything on LF from Natural Radio (sferics)) to 500 kHz, and MedFers. It costs $23 per year in the US. There is often good technical content, and of course loggings. Contact publisher Bill Oliver, 45 Wildflower Road, Levittown PA 19057-3209. I believe mailing him a dollar would get you a sample copy. Haven't seen this reported here yet, as far as I remember. No web presence. 73 Bob k2euh If you guys want to get an idea as to propagation, you might start listening for NDB's in the mean time. Their is an active reflector for that which is here. NDB LIST INFORMATION PAGE (Members Area/Awards/Listening Events pages): http://www.ndblist.info/ To identify what you are hearing you can use this web site. http://www.classaxe.com/dx/ndb/rna/index.php Many of these beacons are running 25 watts to mediocre antennas. ___ UR RST IS ... ... ..9 QSB QSB - hw?

Re: Topband: 1820 BCB
Roger Parsons ve...@yahoo.com wrote: I am over 500 miles north-east of WDOR, and their spurious signal on 1820 kHz is over S9 with me in the past week or so. I do not believe this is intermod as the station modulation is quite intelligible, and it cannot be a coincidence that their fundamental is 910 kHz. It is also extremely unlikely to be generated locally to me as my closest AM broadcast station is more than 100 miles away. I will also send a polite email to the station. 73 Roger VE3ZI Unfortunately the new normal in broadcasting, especially for regionals like this, who typically run 1 to 5 kW, is to arrange for a contract engineer who might 'cover' as many as a dozen stations, and generally be 'on call' to address specific issues. What this means is that there might be a considerable length of time before your inquiry may be dealt with by the station. Many smaller stations are partly to fully automated now and there may be no one to even answer the phone. WDOR is named for Door County, a rural area on Lake Michigan. Many AM's in such an environment struggle to even survive these days. Their incentive to worry about harmonics may be lessened by the realization that the FCC doesn't seem now to care that much. Unless they did something to cause _another_station_ to complain about them to the FCC. That's what gets their attention. The days of a dedicated 'chief' at any particular station are long gone, except (for the most part) for the largest 1A 50 kw-U stations in the largest markets. This parallels the FCC's main enforcement actions these days (access to the 'public file', locking of gates around bases of towers, and emergency alert logging). The lawyers now run the FCC and they enforce that which they understand, and that which generates revenue for minimal effort. Many stations do radiate harmonics from time to time, but most of them being outside ham bands, are noticed only by SWL's who DX them as a 'challenge'. Let us know if they respond.
