[AMRadio] From the ARRL Letter WRC 07 IARU Conference
Subject: [illinoisdigitalham] From the ARRL Letter From the ARRL Letter, Vol 26, No 44 (Friday, November 2, 2007) == WRC-07 SO FAR The end of the second week of the four-week 2007 World Radiocommunication Conference (WRC-07) is drawing near, but -- at least as far as the amateur services are concerned -- the International Amateur Radio Union (IARU) WRC-07 team reports there is not much as of yet in the way of firm conclusions. Here is a report prepared by IARU Secretary David Sumner, K1ZZ. An unexpected highlight of the opening plenary was the announcement by Secretary-General Hamadoun Toure, at the end of his prepared remarks, that he had earned his Amateur Radio license. We seldom, if ever, have received such prominence during the opening ceremonies of a conference. Dr Toure's call sign is HB9EHT. He left for the Connect Africa Summit in Kigali immediately after the conference opening, but is expected to be back in Geneva next week. The Amateur Services have been quite visible at the conference in other ways: * The special WRC-07 issue of ITU News includes an article under Larry Price's byline setting out Amateur Radio's aspirations for the conference. * An Amateur Radio emergency communications trailer brought from Germany was on display during the first 10 days of the conference, parked strategically on the walkway between the conference center and the adjacent ITU building. A full-color explanation of Amateur Radio's emergency communications capabilities and an invitation to visit the trailer was distributed in the delegates' pigeonholes by the ITU Radiocommunication Bureau, as well as some additional information about the Amateur Services, resulting in a steady stream of visitors. * The IARU WRC-07 pin is a popular collectible and is being displayed on many lapels and lanyards around the conference center. * The IARU hosted a very successful reception for 200 key delegates on the evening of October 31 in the ITU cafeteria. * The International Amateur Radio Club (IARC) station, 4U1ITU, is operating under the special call sign 4U1WRC. The station is sporting new antennas that were erected especially for the conference; afterwards they have to be removed temporarily to make way for repairs to the roof of the building. * The IARC has invited delegates to take part, on the last Sunday of the conference, in an excursion to the Swiss National Museum of Sound and Image in Montreux. Progress on the agenda items of interest to the Amateur Services has been slow. The 4-10 MHz issue is bogged down, with opponents of HF broadcasting expansion holding fast to a position of no change. HF BC proponents are not nearly as numerous as in 2003 and are mainly in Europe; they have backed off from an initial position of 350 kHz of expansion down to 200 kHz, but there has not yet been any movement from the other side. In the meantime work on the other 4-10 MHz issues, including the possibility of a 5-MHz secondary amateur allocation (which so far is supported by the European BC proponents), cannot progress. Even if the HF BC allocation could be settled quickly, which seems unlikely at this point, time is running out to complete work on the rest of these issues. Meetings will continue over the weekend and well into next week. Early this week it appeared that the issue of a 135.7-137.8 kHz secondary allocation to the Amateur Service had been settled favorably; however, it turned out that the concerns of some Arab administrations had not been fully satisfied and more work needed to be done. On Friday morning, November 2, the allocation was approved at the Working Group 4C level with two footnotes, one of which limits power to 1 W EIRP and a second that allows countries in Region 1 to opt out of the allocation if they wish. Saudi Arabia repeated its opposition to the allocation and requested that this be noted in the Working Group's report to Committee 4. The allocation still has to be approved by Committee 4 and the Plenary. The next meeting of Committee 4 is scheduled for Tuesday afternoon, November 6. The process of identifying possible frequency bands for future international mobile telecommunications (cell phones and beyond) is very contentious. One frequency range being examined is 2.3-2.4 GHz, which of course is of concern to us although there is no immediate cause for alarm. Prior to every WRC we look for opportunities to clean up so-called country footnotes that allow individual administrations to depart from the regional or international allocations that are in the body of the Table of Frequency Allocations. It is gratifying that several countries have agreed to remove themselves from footnotes that apply to parts of 160 and 80 meters, 6 meters and (in some European countries) parts of 70 cm. With regard to agenda items for future WRCs, discussions will begin in earnest on Saturday, November 3. Proposals have been offered for agenda items dealing with possible amateur allocations around 500 kHz, 5
Re: [AMRadio] the 3600 - 3635 spectrum
Here is some of the local 5 area activity. The way i read the FCC ruling looks they stood firm and didn't let the last minute comments by the special intrest group sway the results. 3600 up for phone. SD With the new FCC ruling that lowered the 80M phone band down to 3600KHz, it was necessary to change our section's ARES PMBO 80M frequencies.As of last evening, both the W0MAC and N5TW have shifted to their new frequencies. With all the various services shifting around, it is quite possible that these may shift again so watch for announcements and always pay attention to the PMBO login banner for breaking news. Here are the frequencies: N5TW3589.0 7063.9 7091.5 10148.0# W0MAC 3592.0 7066.9 7101.2# All frequencies are PACTOR I or II except for those with a # next to them - # indicates a PACTOR III frequency. Also, please note: W0MAC is now operating at it's new Cypress Creek Emergency Call Center location. Ken KD2KW is working to cure an interference problem with the 40M frequency so please use it sparingly until you see a notice from him. - Original Message - From: John Coleman ARS WA5BXO [EMAIL PROTECTED] To: 'Discussion of AM Radio in the Amateur Service' amradio@mailman.qth.net Sent: Friday, December 15, 2006 7:56 PM Subject: [AMRadio] the 3600 - 3635 spectrum Alternate spectrum from 3585 - 3600.

In this Order, the FCC authorized amateur stations to transmit voice communications on additional frequencies in certain amateur service bands, including the 75 meter (m) band, which is authorized only for certain wideband voice and image communications. The ARRL argued that the 75 m band should not have been expanded below 3635 kHz, in order to protect automatically controlled digital stations operating in the 3620-3635 kHz portion of the 80 m band. The FCC concluded that these stations can be protected by providing alternate spectrum in the 3585-3600 kHz frequency segment.

Re: [AMRadio] Interesting FM Bcast Propagation
Take a look here may give some insight as to what conditions were occurring. http://www.dxinfocentre.com/tr_map/archive/6eam.jpg 73 SD - Original Message - From: [EMAIL PROTECTED] To: amradio@mailman.qth.net Sent: Saturday, July 15, 2006 8:06 PM Subject: [AMRadio] Interesting FM Bcast Propagation Hello, I was listening to my usual station 93.9 North Hampton MA yesterday, ( Friday), which is about 50 miles or so east over the mountain when it faded out and was replaced by 93.7 from Albany NY about 40 miles west over another mountain. This reception was swinging between the two stations in a similar fashion to AM QSB but without the phasing for several hours in the afternoon. Tuning in between the frequencies yielded the usual distortion and if I tuned to the 93.7 station it was receiving the same way with the cross fade between the two stations perfect. Now the signals from both stations are normally just at or below the stereo detection point using an SAE 8000 analog tuner. But without the shifting. Antenna is a normal 300 ohm inside FM balanced dipole broadside E/W. I did fire up a wide band receiver to look at the IF spectrum but the signals were so close to the noise floor that any measurements were not possible, although enough of the levels were visible to see the see-saw strength between the two stations. There is a 1000 ft+ N/S mountain ridge immediate west and another one to the east about 5 miles. This behavior has been heard several times especially when there are significant temperature gradients low in the atmosphere. I would suspect that however the reflective or ducting effect is producing this could be visualized as similar to the waves on the surface of a pond reflecting light at a slow rate. IE, consistent, slow ripples over a thermal reflective layer of the ionosphere. I am just surprised at the short distance and would think that there would be technique to take measurements of the distance involved and determine the actual height of the reflective layer. Just an interesting observation of propagation i had not observed before moving here to MA. Has anyone here in the NE ever noticed similar propagation with 6 or 2 mtrs?

Re: [AMRadio] Six Meters AM and a Gonset G50 question
Jim FB on the local qso's on 6AM. The stories about 50.400 getting busy as 29.600 are true , it takes a lot of patience and persistence. You have the right idea always call CQ ,keep an eye on ch 2 TV for signs of a band opening.Another good indicator is the 50Mhz prop logger. Within the last month i have worked about 50-60 stations, most good openings are in the 6-10 pm time frame here in Texas. 2 weeks ago i was there at the right time worked 27 stations in a row ranging from the Midwest to NC SC PA TN KY Etc. Some of the stations were using as little as 2-3 Watts even a couple of Heathkit Sixers. Sporadic E openings can happen at any time this season i had a nice Qso with K6LGL at 11pm one night we talked for quite a while we were both using less than 50 watts. It would be great to work you sometime on tropo if i remember you are located near Austin. I am about 60 miles South of Houston near the coast in EL29. If you like pass along your number and when the conditions are right for a possible contact i can call you.

I can get 20+ miles with S9 reports both ways with a guy with a 3 element beam, and 15 watts. I run about 25 watts output. I am using a ku4ab square loop at about 25'. Last night 6 was hot, and I could hear SSB, and CW from several states. At one point the guys were complaining of too much QRM, and wall to wall signals. Move up to 50.4, and nothing heard. I put out several CQ's on AM, and no responses. When do the AMers on six meters get on? So far I hear mostly baby monitors, old style cordless phones, DSL spurs, HDTV spurs, computer spurs, and only an occasional local AMer. I've heard stories of how 50.4 can get packed like 29.6 FM does. So far I have not had the experience. :( I have a G50 question. Does the power transformer in the G50 get uncomfortably hot to the touch? Mine does. I have turned down the 6L6 idle current in receive (and boost it during receive). That helped a little. I use a variac set to 117 vac. That transformer is hot in about 15 minutes of receiving after turn on. I notice the interleaving of the core is poor, but I am afraid I may have a shorted turn, or maybe these just use cheap lossy iron. With 117 vac in, my DVM shows 390-0-390 from the HV winding. I am afraid to leave my G50 on (squelched) waiting for someone to pop a signal on 50.4 Mhz. Listening to SSB on the G50 using the VFO spot feature is not too good. I played with my audio generator (goes to 455 kc) and put a two turn coil around the G50 last IF tube. That works pretty good if you set the level for about 20 over 9 on the S-Meter. Looks like I need a BFO to be made up. Any thoughts about the hot biscuit transformer?
