10th Anniversary Giveaway!

On April 30th, it will be ten years since the "W2LJ - QRP - Do More With Less" blog was born.

In appreciation for all who read this blog, I am going to give something away to one lucky reader. I have a new, mint condition, unused, complete sheet of fifty United States Amateur Radio stamps, issued in 1964 on the 50th Anniversary of the ARRL - Scott #1260. I am going to have the sheet matted and framed - ready for display on some deserving shack wall. All I ask is that you send an e-mail to w2lj@arrl.net - entitled "Blog Anniversary Giveaway". Include your name, call sign and mailing address.

Any Amateur Radio op worldwide can enter. I will package and ship the framed stamps to any destination that the United States Post Office will accept.

The names and call signs will be loaded into a software program such as RandomPicker on April 30th and a winner will be determined. The winner will be announced here, and then the framed stamps will be posted.

Good luck, and thank you for reading!

RF pollution is maddening !!!!

RF pollution is maddening! It ruined my evening last night during Run For The Bacon; and it reared its ugly head again tonight.

Last night I was able to copy all of two signals. The local noise was 10 over 9. I gave up after a half hour of pure frustration. Tonight started out a lot better. I was having a QSO on 40 Meters and the band noise was normal. Fortunately, it was at the END of my QSO when someone flipped a switch and the 10 over 9 hash came back with a vengeance!

I don't know what it is that is causing such horrendous interference. It's not anything in my house as the kids were asleep and my wife was working. I had nothing inside the house turned "on" that could generate so much noise. This noise HAS to be coming from a neighbor's house. A plasma TV perhaps; or a device like it?

It's not going to be easy to identify. Even harder will be explaining to the neighbor how his appliance is screwing up my radio!

Hello Larry: Perhaps you might want to look here, for help with interference:

KB9UKD’s Digital Modes Sample Page
VE3HLS’ RFI Noise Identification Page
I believe I’ve written before about the Digital Modes Sample page, but the RFI Noise Identification page was a new one for me. The page has 20 or more .mp3 files of various types of noise in the following categories:

Household appliances and electrical equipment
Computers and related equipment
Transmitters and intentional RF emitters
Electric Utilities , BPL and industrial equipment
Miscellaneous Equipment

I've recently discovered why dimmer switches have their reputation.

All my equipment is located in a shop room in my garage. My problematic dimmer switch is located in the master bedroom, a room which is literally on the opposite side of the property from the garage. You couldn't put the two farther apart. If the switch is on, I get an S9 buzz on everything, everywhere.

This little dimmer switch is so bad that it even screws up the AM radio when I pull into my garage.
