Almost all the presentations are made at the meetings of all three Oregon SBE Chapters.
The Eugene meeting is usually the day after the Portland meeting.
The Medford meeting is usually two days after the Portland meeting.
The Portland meetings are held at lunchtime on the second Tuesday of every month. Everyone is welcome to attend the meetings. When you get to the Buffalo Gap, go in the SW California Street-side door, turn left, and go upstairs. We have the whole upper floor, which has its own bathrooms. Be sure to get there early, because after the Gap's parking lot fills up you'll be searching the narrow streets for blocks around to find a place to park. For more information on Chapter 124 in Portland/Vancouver/Salem, contact Chapter Chair Ev Helm, e-mail chairman at sbe124 dot org, or call him at 503-977-7752. For a map and directions see http://www.sbe124.org/SBE124_maps.html .
Steve Holmes, Tektronix Video Application Engineer, did a presentation on the Loudness/CALM Act in Transmission Testing - Practical Application of the methods the FCC is most likely to use for determining violations of the CALM Act.
Detailed info here.

Bob Surette of Shively. The title of his presentation is: "The Good News that 10 dB is Here - The bad news is that 10 dB is here!"
This presentation is for those engineers who are on the air now with the original -20 dB IBOC injection level and are thinking of increasing to the new -10 dB IBOC injection level. I will discuss the different methods of IBOC injection and what happens to the hardware when the IBOC injection power level is increased. I will also discuss how the peak power levels of combined systems are calculated so that multi-station systems can be evaluated before the IBOC power level is increased. (There are 14 FM HD stations in the Portland radio market.)

Just when you thought you could forget about ionizing radiation exposure... Here's a link to a graphic that shows that it is all relative. (Thanks to the CGC Communicator for the link.)
All the current exposures are in micro- and millisieverts. Remember rems? 1 sievert = 100 rem. From Wikipedia: "Professor Rolf Maximilian Sievert (6 May 1896 – 3 October 1966) was a medical physicist whose major contribution was in the study of the biological effects of radiation."
Alpha is simulcasting 750 KXL on 101.1 which is now KXL-FM, bringing "News/Talk" to the mysterious FM band but with the stereo pilot turned off. The format change was kind of weird for me having once been Chief Engineer of each of them. I went to the privately-held KUFO wake at a bowling alley. They have parked the KUFO call letters on 970.
However, they may be onto something. 50 kW 1500 WTOP Washington DC began simulcasting their all-news format on 103.5 FM then changed the AM's format to "Federal News Radio" and the call letters to WFED. Now WTOP on FM is the top billing radio station in the country: $57 million last year. WDC is the #9 radio market. The #2 billing station is KIIS-FM in Los Angeles, the #2 radio market.
Not to be completely outflanked, Clear Channel's1190 KEX now has an FM translator on 102.3 with a blistering 99 Watts from Mt. Scott. View the 60 dBu coverage map here.
Alpha already has Sports on 95.5 FM The Game KXTG, but it has yet to really beat Entercom's 1080 The Fan KFXX. Some folks think that Alpha will someday put The Game on 750, and put music back on 95.5, possibly to compete with Clear Channel's103.3 K103 KKCW which has been #1 for years and was in the double-digits (hard to do with PPM) in the Holiday ratings.
On March 11th, my wife Patti and I were asleep in a hotel room in Cannon Beach when the phone rang at 3:45 AM. "Please meet in the lobby at 6 AM prepared to walk to higher ground" the woman at the front desk said. Looking at The Weather Channel and seeing that nothing was going to happen there until about 7:30 AM, we immediately packed up, went home, and went back to sleep.
I'm not going to the coast again without my NOAA Weather Radio. Had we heard the Tsunami Warning at midnight, we would have gone home then!
http://replay.waybackmachine.org/ . They have somehow archived whole web sites starting in the 1990s. I was the first webmaster of www.kufo.com and there is a copy of it from 1996. Unfortunately they don't have www.thebeat.com when it was only on AM.
They have revamped hdradio.com. They finally removed all the former CBS-Portland stations which never added HD.
There are 14 FM HD signals (twelve with HD2, and two of those have an HD3) and three AM HD signals on the air in the Portland market. Go here for a complete list.
There are now over 1000 multicast stations and 100 HD Radios to choose from. See the buyer's guide here.

The net meets on the 1st and 3rd Saturdays of the month (except in August) at 10 AM Pacific Time. The SBE IRLP HAMnet is based in Denver using the NØPQV Rocky Mountain Radio League repeater, IRLP node #3350, And national and worldwide via the IRLP reflector 9615. All of this information can also be referenced at http://www.sbe.org/sections/IRLP.php.

To find a node in your area you can go to the www.irlp.net website, click on the "Node Info" on the left, then click on the "List of nodes and frequencies" in the middle of the page. In a moment a full list of node numbers, cities, countries and the like will appear and do a page search for you city. When the node is highlighted click on the node number and that repeater information will appear, usually with contact information of the trustee/repeater owner. When you have done this and are able to access your node (usually at 4 digit code on the local repeater unless it is a closed club system), you will want to connect to the Denver Reflector Node #9615.
If you need further help contact me at KEØVH at qsl dot net .
[A good Portland node is 3420, N7PIR at 440.450 with a PL of 103.5 Hz, now located on the Skyline Tower. SBE 124 <1 GHz frequency coordinator Mike Steiner KD6LVP is the trustee. See http://www.qsl.net/n7pir .]
