Motion-detected and timestamped screenshot of an HD Radio decode picked up by the WyzeCam on 1/19/18.
DXers with RDS and HD Radio-capable receivers now have a new and interesting way of seeing everything that comes across their radio’s screens while they are away — literally.
Wyze is a home security camera company that sells “WyzeCam,” an HD-quality home security camera. I purchased a few cameras for my home in the previous month, and I have used them for their intended purpose until I realized that the device opens up a new world of capabilities for the average DXer.
Although I always have two radios continuously recording during the Sporadic E season, the problem is that I can only record audio from them, not screenshots unless I was Continue reading →
Every hour as a child and teen, I’d hear one phrase echo off of the walls in my bedroom:
“Z104 is WWVZ Braddock Heights/Frederick, WWZZ Waldorf/Washington, DC.”
It’s the legal ID of a radio station I’ll never forget.
The Washington, DC market had three full-time CHR stations in the 1980s: 105.1 “Power 105” WAVA, 106.7 “B106” WBMW, and 107.3 “Q107” WRQX. Unfortunately for area listeners, these signals slowly left the format one by one — WBMW in 1988, WRQX in 1990, and WAVA in 1992, leaving Washington without a CHR station until 1996, when Z104 debuted.
Z104 was actually two signals: 104.1 WWZZ covering southern Maryland and the south and eastern suburbs of Washington, previously classic hits WXTR “Xtra 104,” and 103.9 WWVZ, which covered the nearby small market of Frederick, MD. Prior to its debut, WWVZ was CHR as “Z104,” but it was an unrelated station that was replaced with the new Z104 simulcast.
The new signals often referred to itself as “The Z,” its music as “Z tracks,” and the capitol city as “DZ” instead of “DC.” From the get-go, it was obvious that station management knew that the Washington market was without a CHR station for the better half of a decade. Because of this, the station ingeniously Continue reading →
Could there be a radio better than the Sony XDR-F1HD? My answer would have been a resounding “no,” that is, until I came across the Airspy R2.
The Airspy R2, which retails at $169 as of the time of publication, is a software-defined radio, or SDR. A “mini” version with a few less bells and whistles retails for $99. With an SMA to Coax adapter, $5 on Amazon, the supplied USB wire, and free SDR tuning programs (more on that below), you have all you ever need for Continue reading →
DXing can be a very social hobby. With annual conventions, message boards, and email lists giving DXers a chance to be heard worldwide at the click of a button, it can be hard to keep anything to yourself.
Advances in technology in the past decade has made it simple to share anything and everything about DXing on multiple social media and file sharing platforms. One could post a dial scan video on YouTube, photos of their shack on Facebook, or a reception report on a propagation logger. It can bring people with like interests together in an inviting environment, as well as allow new people to discover what DXing has to offer. It’s easy to be social in today’s world.
My beloved Sony XDR-F1HD radio recently developed a problem where its audio output became garbled with a hum, rendering it useless for DX. As I often used the F1HD on airplane trips where bringing my larger radios were impractical, I have been on the search for a replacement radio with HD Radio capabilities. I found the Insignia NS-HDRAD2, which at the time of writing, is $49.99 at Best Buy, but is cheaper on eBay.
I’ve been eyeing this radio for some time, but shied away from purchasing it due to a less-than-stellar review from a friend who bought it and returned it to Best Buy last year. Given its cheap price, I thought I would give it a chance. I’m glad I did.
For the past few days, local 96.3 WHUR Washington, DC’s HD Radio signal, which airs on 96.1 and 96.5, has been off-air. Usually, 96.1 and 96.5 are extremely difficult to DX since WHUR’s digital sidebands are strong at my Northern Virginia home. However, with WHUR-HD turned off, both of its adjacent frequencies were open to distant reception like they were prior to 2006 when HD Radio debuted on WHUR. At 8:50 PM February 8, WHUR’s IBOC sidebands resumed its broadcast.
The above chart shows a waveform of 96.5 FM from 8:49-8:50 PM February 8. In the beginning, you can see a fairly strong analog signal from 96.5 WKLR Ft. Lee, VA, 92 miles away. At the 0:05:00 mark, WKLR’s signal decreases as WHUR’s HD revs back up. at 0:09:50, WHUR’s 96.5 digital sideband is at full-power, and WKLR abruptly disappears without a trace.
Listen to the corresponding audio file to the graphic above.
Three years ago, I wrote about the rising amount of FM translators that have popped up in the Northern Virginia suburbs of Washington, DC and its effect on FM DXing. I am updating this article as the local radio landscape has greatly changed since my original 2013 article.
FM translators are low power rebroadcasts of either a full service FM or AM signal. Or, they can be a relay of an HD Radio subchannel of a nearby signal. LPFMs, or low-powered radio stations, on the other hand, can originate their own programming and often operate as a community radio station, complete with live and local content.
For the most part, the radio dial in Northern Virginia is much worse than it was in 2013 due to the existence of these signals. Many of my good, quiet DXing frequencies are gone, replaced instead by a repeater of a signal that I can already get strong elsewhere on Continue reading →
This radio will, for the most part, serve as my new go-to radio for dial scanning, since it has built-in speakers. My other two main radios, the Sony XDR-F1HD and the Denon TU-1500RD, have their audio outputs connected to my computer. Since the S10 has speakers, I can now easily check reception conditions without Continue reading →
Imagine turning on your radio to listen to your favorite station to find nothing but static. You hit the ‘seek’ button and it dances from 88.1 to 107.9 multiple times without stopping. And yep, your antenna is connected and it is operating just fine. It’s surely a DXing nightmare–something that will soon be a reality for DXers living in Norway.
