Some people got pretty upset about this.&nbsp; The fact is, however, that sdr.hu was only peripherally involved with KiwiSDR. The receivers incorporate code built on a fork of its owner's earlier OpenWebRX program, for which he gets compensation.&nbsp; There are four other ways to get to the receivers without logins, brain-melting CAPTCHAs, and requirements that you have a ham call or make one up

With the government shutdown over, the National Park Service has re-opened the KPH receive building to normal use. All call signs should be on-air this Saturday. But, as always, there's a catch.&nbsp; A strong storm took down trees, destroying a number of feedlines to antennas. The damage includes broken poles and snapped wires, and generally it's a mess. Repairs will take time and cost money.

Here's a screen shot from about 15 minutes ago, on the 12 MHz frequency via the SDR at KPH using the big TCI antenna in a low-noise location.&nbsp; Faxes received in this manner usually print just fine, so the problem is not caused by remote Internet reception. Note the extremely noisy signal, the downward displacement of the white tone, the absence of a black tone, and the distortion

For several weeks now, all NOJ radiofax transmissions from USCG in Kodiak, AK have been off-frequency and severely distorted. It's possible to get something resembling a chart by tuning to wherever the white frequency is at the moment, but even then it's fuzzy at best.&nbsp; Signal strength is not the problem, because the distortion happens on all frequencies and time slots, regardless of the

The Russian "Squeaky Wheel" marker has been around for many years.&nbsp; It's a channel marker for a military network. It used to be designated XSW, but then Russian voice traffic appeared, and it was changed to S32. Today, however, the sound has changed, at least for now.&nbsp; It's now three audio frequencies instead of two, so the "wheel" really needs oil. This spectrogram was made from the U

I sent my column in this morning, so it was time for something important to happen. It always does after I don't have time to put it in. This time, it's HFDL rolling out System Table number 51.&nbsp; It adds a new ground station, number 10.&nbsp; The coordinates, return to a site in southwestern Korea. The Google Earth image is a bit old, but it does show a definite antenna farm under

This affects both 490 and 518 kHz. Kerkya is using the same letters and time slots. The only differences are the transmitter location and government operators.

Your radio isn't busted.&nbsp; A variety of events affecting the Earth's magnetic field have caused one of the longest geomagnetic storms in recent memory.&nbsp; The K index has reached 7 on a number of occasions in the last three days, and this is expected to continue on and off.&nbsp; K is back to 7 as of this writing.&nbsp; Surface events such as ground currents in Norway have taken place. We

From ARRL Letter: ARRL members and Amateur Radio clubs are expressing increased concern over the inclusion of WWV and WWVH on a list of proposed cuts in the White House's National Institute of Standards and Technology (NIST) Fiscal Year 2019 budget request. The proposed cuts, which only recently came to light, would also include the Atomic Clock signal from WWVB. Online petitions soliciting

Shit. That's all I can say.&nbsp; This may be the first time anything to do with radio has made me ruin my vocabulary in public. As our headline indicates, the proposed FY 2019 budget for the U.S. National Institute of Standards and Technology includes the elimination of WWV and WWVH: -$6.3 million supporting fundamental measurement dissemination, including the shutdown of NIST radio stations

I finally got a good fix on a station with the KiwiSDR TDoA extension.&nbsp; It's tricky, but for a system available to the public, it works amazingly well.&nbsp; The instructions that are given from the "Help" button are accurate. That's how you do it.&nbsp; The secret is indeed to use the minimum possible passband in IQ mode, and to pick relatively close receivers. Here's a plot of the French

You've probably been playing around with the huge KiwiSDR network which can be reached from http://sdr.hu/ . Just this week, too late to put into the column, it has rolled out a new beta with a recorder and a Time Difference of Arrivial (TDoA) direction finder. Both seem pretty slick. The recorder is self-explanatory. You click a big red button over on the top right of the control panel, and it

RD passes along the following: The correct station phone number is: +1 415-669-9646 . The number is answered only when the station is on the air. We mentioned that on-air operations will start at 5:01pm Pacific time (0001Z 13 July) but didn't say how long operations will continue. We usually continue live operations until about 9:30pm Pacific time (0430Z). At that point K6KPH operations

Is it really 19 years? Be that as it may, here is full information on the annual triumph of the human spirit also known as MRHS Night of Nights. Notice the absence of the US Coast Guard, not to mention WLO, which has left the air. Be that as it may, the fun continues. MRHS: NIGHT OF NIGHTS XIX INFORMATION Yes,
