The LOWDOWN This Month
In the May 2012 issue of the club publication:
- "DX Downstairs" Kevin Carey presents members' LF and VLF loggings.
- "On The Air" Experimenters operating on the 160-190kHz and 136kHz bands... and...
- "The Top End" MedFER and HiFER beacon lists... and...
- "The LF Notebook" Conducted by John Davis. The full story on reception of HiFER NC in New South Wales, plus other LF and Part 15 radio happenings for, from, by, and about LWCA members.
- "News From the Old World" Alan Gale keeps us informed of LF experimentation on the "other side of the pond."
- "Peoduct Review: Honda EU2000i Generator by John Davis. A good candidate for powering portable DX sessions?
- "On The Longwave Trail" This time Kriss Larson takes us to Norfolk Island and New Zealand.
- "Natural Radio" Conducted by Mark Karney.

NC Beacon Captured in Australia
Steve Olney VK2XV appears to have captured HiFER NC at a distance of 15,400 km (about 9,548 miles), a record which will be exceedingly hard to surpass. Read his message in the LW Message Board for more information and a view of the capture.

| | New Amateur MF Allocation Approved
472-479 kHz OKed on Secondary Basis at WRC-12 on Feb 14.
By this time next year, amateur radio operators in much of the world may be able to operate in the new slice of spectrum, after the changes are published in the ITU Radio Regulations and individual nations formulate their own rules for the band. Although a narrower band than earlier hoped, it is a significant step forward.

•William Hepburn's DX Information Centre features many kinds of DX resources, including much on services found at LF and VLF; for example, regularly updated lists of NAVTEX and TWEB (Transcribed Weather) stations, LF/VLF time signals, and longwave broadcasters. Visit the site at its new location:
DX Information Centre. Don't overlook the pages for higher frequencies, and the propagation forecasts as well.
•Radio Waves Below 22 kHz Renato Romero's eclectic collection of topics pertaining to both manmade and natural radio signals from near DC to the upper end of audibility. Includes the VLF Open Lab, and articles by many contributors...some fairly orthodox, and some not. Visit: www.vlf.it

| | QRSS and WOLF Software
Rik Strobbe's QRSS software (for transmitting extremely slow CW) is usually available from our file library, but while it is temporarily out of service, you can obtain QRSS and Rik's other useful software at the ON7YD download page.
Continuing Development of Argo. Alberto di Bene regularly posts the latest version of Argo, a receiving tool for displaying slow CW, that performs FFT spectral analysis and displays it in ways optimized for QRSS. Many of the transoceanic LF amateur records were set using Argo at the receiving end. Argo has somewhat similar performance to Spectran, but interacts better with the user's soundcard and is customized for QRSS modes.
WOLF. Stewart Nelson devised this unique mode, a variant of BPSK. See his announcement of the MS-DOS version for more details. Now, a GUI-based version by Wolf Buscher continues to increase the mode's popularity. Find the new software at the DL4YHF site.
Slow CW for Linux. Claudio Girardi (IN3OTD) has released Slow CW software for users of the Linux operating system, currently v 0.42. The program (called glfer) contains both transmit and receive capability, the latter including an FFT-based spectrum analyzer somewhat similar to those found in popular Windows Slow CW programs.
As with much open-source software in the X-world, you have to compile the C source code yourself. Users will also need additional code libraries. Links to those, plus downloadable source code, can be found at Claudio's glfer page.
