+ Legislative News: ARRL Members Respond to HR 607

ARRL Regulatory Information Manager Dan Henderson, N1ND, gives some hints for how to draft a letter to your Representative in opposition to HR 607.

Last month, a bill was introduced in the US House of Representatives that addresses certain spectrum management issues, including the creation and maintenance of a nationwide Public Safety broadband network. This bill -- HR 607, known as The Broadband for First Responders Act of 2011 -- if passed, also calls to auction off parts of the 70 cm band, namely 420-440 and 450-470 MHz. As such, the ARRL asked its members to write their Representative, asking them to not support HR 607 in its current form.

According to ARRL Regulatory Information Manager Dan Henderson, N1ND, Chwat & Co -- the ARRL's legislative relations firm in Washington, DC -- received almost 1000 letters from League members in opposition to HR 607. "This is a great start and many thanks to the diligent members who have risen to the challenge; however, it cannot stop there. As long as HR 607 is in its current form, we must continue this campaign." He clarified that the ARRL opposes HR 607 in its present form: "We do not oppose the concept of dedicated spectrum for the development of a Public Safety infrastructure and wireless network. We object to the bill because of the inclusion of 420-440 MHz as part of the spectrum to be swapped and auctioned to commercial users."

+ Get Ready for the April Issue of QST!

No foolin' -- the April issue of QST is jam-packed with all sorts of things that today's Amateur Radio operator needs. From product reviews to experiments to contesting -- including articles featuring a homebrew 40 meter transmitter, ground radials, digital modes and the 2011 ARRL Board of Directors Annual Meeting -- this issue of QST has something for just about everyone.

Who says life's too short for QRP? Not Lou Burke, W7JI. Following up on his February 2011 QST article about a homebrew QRP superhet receiver, Burke brings us "The W7JI Low or Lower Power 40 Meter Transmitter," a companion to that receiver. This transmitter features a VFO, CW keyer and automatic antenna switching. Ron Harger, WD8BCS, shows readers an inexpensive and easy-to-build radial system for temporary vertical antenna installations in his article "Does Your Ground Radial Kit Measure Up?" When you keep your audio controls in check, it really does make a difference in how your station sounds. QST Technical Editor Joel Hallas, W1ZR, demonstrates how to set up your SSB transceiver with the proper audio levels in "Sounding Good on the Air -- Setting Your Audio Controls."

Amateur Radio is all about experimentation. One of the newer ways for hams to have fun and play around on the bands is via the digital modes. QST editor Steve Ford, WB8IMY, takes a look at one of the newer digital modes in "JT65 -- The 'Musical' Mode." In January, the ARRL Board of Director met in Connecticut for its Annual Meeting. Join ARRL News Editor S. Khrystyne Keane, K1SFA, and QST Managing Editor Joel Kleinman, N1BKE, as they take you inside the meeting room as the Board charts the course for the coming year and beyond. Keane also tells of the recipients of the ARRL International Humanitarian Award, the George Hart Distinguished Service Award and the print, video and audio winners of the Bill Leonard, W2SKE, Professional Media Award.

Take a look at the Elecraft P3 panadapeter and Uniden HomePatrol-1 scanning receiver (pictured, with ARRL Lab Test Engineer Bob Allison, WB1GCM), featured in the April 2011QST product review.

QST Technical Editor Joel Hallas, W1ZR, takes a look at the Elecraft P3 panadapter in this month's Product Review. He says this add-on to Elecraft's popular K3 rig "adds high performance, stand-alone functionality. If you want to see what's happening on the band, this will provide the needed view, as well as another way to control radio tuning, if you wish." ARRL Contributing Author Curt Phillips, W4CP, checks out the Uniden HomePatrol-1 scanning receiver. He says that it "brings user friendliness to a new level. It performs complicated scanning functions with ease, and loading local frequencies is a snap."

Carl Luetzelschwab, K9LA, delivers the results of the 2010 IARU HF World Championship, held this past July. What makes this 24 hour contest so much fun? "Everyone works everyone, we get to operate both CW and phone, the exchange is simple and we get to work HQ stations and receive their nifty QSLs," said one participant. "It's also during the summer break, which allows busy college students to take it seriously." ARRL Regulatory Information Manager Dan Henderson, N1ND, tells about the 2011 ARRL Straight Key Night. As one participant described it, Straight Key Night participants appreciate "the opportunity it affords us Old Timers to relive the past in such a wonderful way."

Of course, there are the usual columns you know and expect in the April QST: Happenings, Hints & Kinks, The Doctor Is IN, How's DX, Vintage Radio and more. Look for your April issue in your mailbox.

The Doctor Is IN : Measuring a Meter's Tolerance

David Van Doorn, W9WEL, of Fort Wayne, Indiana, wrote to the ARRL's Doctor, asking about his analog meter's tolerance. He wanted to know if the tolerance is listed as 10% of full scale, does that actually mean ±10% of full scale? For example, a meter with a 300 unit full scale would have a specified accuracy of the measured value of ±30. Thus, a reading of 40 could actually be anywhere from 10 to 70. Or does that mean ±10% at full scale? For example, at 300 full scale, an actual value of 300 could read 270 or 330 and every other reading on that scale would read ±10%? So an actual value of 40 could read 36 or 44?

Here's what the Doctor had to say:

I'm afraid it is the former. This suggests that the scale selected be one with the reading near the top of the range for maximum accuracy. Keep in mind that the actual accuracy could be -- and often will be -- much better than that specified, just not worse.

Thanks Doctor! Do you have a question or a problem? Send your questions via e-mail or to The Doctor, ARRL, 225 Main St, Newington, CT 06111 (no phone calls, please). Look for "The Doctor Is IN" every month in QST, the official journal of the ARRL.

+ Public Service: No HF Frequencies Being Used in New Zealand Earthquake Operations

The ARRL has received word from the New Zealand Association of Radio Transmitters (NZART) -- that country's IARU Member-Society -- that amateurs there providing communications support in the aftermath of the 6.3 earthquake are using 2 meters (144 MHz). No HF frequencies are being used. If this changes, the information will be posted on the ARRL website.

Solar Update

The Sun, as seen on Thursday, March 3, 2011 from NASA's SOHO Extreme Ultraviolet Imaging Telescope. This MDI (Michelson Doppler Imager) image was taken in the continuum near the Ni I 6768 Angstrom line. The most prominent features are the sunspots. This is very much how the Sun looks in the visible range of the spectrum.

Tad "Waiting for the Sun" Cook, K7RA, reports: Solar activity is on the rise again, but the average sunspot and solar flux numbers are down, compared with last week. This week, the average daily sunspot number declined more than 14 points to 50.9, and the average daily solar flux was off 7 points to 96.8. The average daily planetary A index rose from 6.1 to 9, and the average mid-latitude A index was about the same, declining from 5.4 to 5.1. The most active day for geomagnetic indexes was March 1, with a planetary A index of 31. The planetary K index rose as high as 6 on that day. NOAA and USAF predict solar flux at 115 on March 3, 120 on March 4-10, 110 on March 11-15 and 105 on March 16-17. The planetary A index is forecast at 15, 12 and 10 on March 3-5, 5 on March 6-13 and 7 on March 14-15. The monthly average of sunspot numbers for December through February was 22, 32.2 and 53.5. Look for more information -- including a take on why Solar Cycle 24 has been so weak -- on the ARRL website on Friday, March 4. For more information concerning radio propagation, visit the ARRL Technical Information Service Propagation page. This week's "Tad Cookism" is brought to you by The Doors' Waiting for the Sun.

In the March 3 edition of The Daily DX, Editor Bernie McClenny, W3UR, reports that the planned DXpedition to the Spratly Islands has been postponed until April 2012. According to DX0DX Team Leader Chris Dimitrijevic, VK3FY, the postponement is due to circumstances beyond the control of the DX0DX Team and "in the best interests of the Team of Operators."
