Isaiah 40:28-29 / Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. He gives strength to the weary and increases the power of the weak. (NIV)

National Hurricane Conference: Amateur Radio Sessions
The three Amateur Radio presentations will be recorded and streamed live on the Internet by James Palmer, KB1KQW at, www.nsradio.org/stream.htm and www.voipwx net/files/stream.htm
The National Hurricane Conference will be held next week, March 25-28 at the Hilton New Orleans Riverside in New Orleans, Louisiana. There will be several Amateur Radio activities going on during the week, especially on Monday. The National Hurricane Conference (NHC) leadership continues to recognize the valuable contribution of ARES and again invited us to participate with three sessions, as follows:
NHC Session #1: Monday, March 25, 2013 from 10:30 am to 12:00 pm. This is the main Amateur Radio session of the National Hurricane Conference and will cover Hurricanes Sandy and Isaac Amateur Radio responses.
NHC Session #2: Monday, March 25, 2013 from 1:30 pm to 3:00 pm. This session will cover Amateur Radio at the National Hurricane Center, the WX4NHC Haiti Earthquake Mission, VoIP Hurricane Watch Net and will feature special guest speaker Dr. Rick Knabb, Director of the National Hurricane Center.
NHC Session #3: Monday, March 25, 2013 from 3:30 pm to 5:00 pm. This session is designed for Emergency Management personnel and is entitled "Amateur Radio Rap Session - The Emergency Manager's Hidden Resource." This is an increasingly popular session where Emergency Management personnel from all over the country interact with ARES personnel on aspects of disaster communications.
All hams are invited, at no cost to attend the Amateur Radio sessions at the National Hurricane Conference.
Ferreting out noise sources
By Dan Romanchik, KB6NU
About three months ago, I put up a 20m antenna-an end-fed, half-wave antenna (http://www.kb6nu.com/kb6nu-finally-builds-an-end-fed-half-wave-antenna/). Right off the bat, I was flummoxed by the high noise level. It was nearly S9, obliterating all but the strongest signals.
The strange thing about this noise was that I was only experiencing it on 20m, and only using this antenna. If I switched to my 40m dipole, the noise dropped back to the S1 - S2 noise level that I usually experience here. (Yes, I know. I'm really lucky to have such a low noise level here.)
It didn't really make any sense to me that this antenna would be so susceptible to noise while my other antennas weren't, but I just couldn't come up with any other explanation. I was not experiencing any noise on any of the other bands, after all. Sometimes 40m is so quiet here that I check to make sure that the antenna is connected to the radio.
As luck would have it, I stumbled upon the noise source a couple of days ago. I had taken the laptop I normally use in the shack somewhere one day last week, and when I returned it to the shack that evening, I switched the rig over to 20m before connecting the power supply back to the laptop. No noise! When I plugged the power supply into the laptop, the noise jumped up to S9 again. The problem noise source was found!
I posted about my experience to my blog and to the HamRadioHelpGroup (http://groups.yahoo.com/group/HamRadioHelpGroup/). Mark, K5LXP, one of the gurus on HRHG, advised me to throw the main circuit breaker in order to determine if it was something inside the house generating the noise. Bob, K0NR, commented on my blog post, "I have found that flipping off circuit breakers in my house is a good first step to try and find a noise source. Usually ticks off the family, but what the heck :-)" Either of these methods will help you determine if a noise source is inside or outside of your house.
I'm still thinking that the way my antenna is positioned may have something to do with its picking up the noise generated by the power supply. I plan to play around with the positioning of the antenna once the snow melts and see if that makes any difference. Until then, I can work 20m with the power supply disconnected and run the laptop off the battery.
So, the next question you might ask is how does the antenna work? It seems to be putting out a very good signal. One evening last week, I worked several DX stations, including 6W/HA0NAR in Senegal. It's not a beam, but I'm pretty happy with it.
