On September 9, 2020, I experienced a mammoth tropospheric duct opening which brought stations from Nova Scotia and New England to my home in northern Virginia, at distances up to 813 miles away and bringing in 30 new stations logged.
Although a few months have passed since this record-breaking opening, I kept about six hours of RF recording from roughly 95.1-103.5 FM recorded during the overnight hours and finally had some time to really go over it all in-depth. The result of my deep review is the revelation of four more new stations from the opening, bringing the grand total to 34 new stations logged.
My FM DX Log has been updated with the new stations listed below.
95.9 WATD-FM Marshfield MA, 420 miles
96.1 WSRS Worcester, MA, “96-1 SRS” – AC, 378 miles
97.7 WCTY Norwich, CT “97.7 WCTY” – country, 335 miles
102.3 WMOS Stonington, CT, “102.3 The Wolf” – country, 344 miles over local 102.3 WMMJ
Radio signals from Nova Scotia were heard over 800 miles away in Northern Virginia during a massive tropospheric ducting event in the overnight hours of September 9, 2020.
The duct, which began shortly before midnight Sept. 8, also brought in sustained signals from Massachusetts, Rhode Island, Connecticut, and New York with distances over 400 miles away continuously until about 11 AM. Other DXers in New England reported receiving signals from near my home in Virginia at comparable distances, and a reader in Nova Scotia told me that she also received stations from Massachusetts during the event.

I turned on my radios at 11:44 PM Sept. 8 and immediately found 98.1 WCTK, a never before-received signal from New Bedford, MA at 393 miles away, booming in with decoded HD Radio. Soon after, I found more signals from throughout New England coming in.
The golden prize of the opening didn’t occur until 1:36 AM, when I discovered a weak signal from 103.5 CKHZ-FM Halifax, NS in Canada coming in right over local 103.5 WTOP. CKHZ-FM, at 813 miles away, is now the furthest radio station I have received via tropospheric ducting, unseating my previous record set in 2005 by 99.9 WQRC Barnstable, MA at 420 miles away. It also marked the first time that I received a different country on the radio dial at my home via tropo. WTOP is a very strong local signal at 21 miles away from me, so the fact that CKHZ-FM was able to come in over it is simply amazing. Two other Canadian stations from the Halifax area of Nova Scotia, previously-logged 95.7 CJNI-FM and 100.1 CIOO-FM, were also heard. All in all, I received 30 new radio stations during the opening. A list of these new stations can be found further below in this post.
The opening also gave me my first “three prong” signal–a signal that was heard separately, at different times, via the three major radio signal propagation methods: Sporadic E-Skip, meteor scatter, and tropospheric ducting. That station is Halifax’s 100.1 CIOO-FM. I first heard CIOO-FM via meteor scatter propagation on Sept. 20, 2006 and a few times since then via skip. Given limitations related to propagation and distance, having a three prong signal is very rare and it took me 21 years to get one.
Tropo enhancement with signals coming in over 400 miles away as observed in this tropo duct is common in the southeastern USA and Gulf Coast, but it is unheard of in the Mid-Atlantic region of the country where I live. DXers in New England will, occasionally, receive stations from Virginia and the Carolinas, but the reception is usually one way and I don’t benefit from it as the endpoints of the duct are usually out of range for me. My distant receptions to north and northeast often bottom out at New York City, which is 225 miles away. These stations are usually in for less than an hour before the duct falls apart and they disappear. To have an all-night opening bringing signals 400-820 miles away is something that just doesn’t happen in my area.
Throughout the opening, many of my local Washington, DC and Fredericksburg, VA radio stations were fighting with New England stations for control of the frequency. Some local signals were simply gone off the dial without a trace, with multiple distant signals coming in all at once in place of them. The pile-up of so many signals coming in at once reminded me of the once-in-a-lifetime colossal July 6, 2004 sporadic E opening, where almost every local radio station of mine disappeared to far-away signals coming in from the Midwest.
Below is a list of the stations I received from the tropo opening, including HD Radio and RDS screenshots, which have been added to my RDS/HD Radio Screenshots Gallery page. For brevity, I have only included previously-logged stations beyond 150 miles away that I don’t usually receive at my home during DX events. My FM DX Log has also been updated with the new content.

The past month or so has been fairly quiet at my home in Northern Virginia in terms of FM DXing. Constant storms and unfavorable weather conditions paved the way for non-existent DX outside of regular, garden-variety enhancement of signals within 100 miles.
I realized that I never posted about a few new FM logs received two months ago. Exceptional tropospheric enhancement brought in signals up over 300 miles away to the south–a rare event nowadays–during the late morning hours on July 16. 103.1 FM at my home during most tropo events is WRNR Grasonville, MD, at 61 miles away. Instead of WRNR’s AAA format, I heard oldies music while tuning by. I then caught a legal ID from 103.1 WLQC Sharpsburg, NC, a new log at 189 miles. .

Shortly afterward, I tuned past 91.3 FM and saw an immediate RDS decode from new log WHQR from Wilmington, NC, 317 miles away.
A few days later, on July 19, I took a day trip to nearby Fredericksburg, VA. While there, I heard two new signals: 91.5 W218CV and 106.3 W292EF, both from Fredericksburg. Both stations aired a religious format and were new since my last visit to the area several years ago. Since Fredericksburg is less than 30 miles away from my home, I am adding these new logs to my FM DX Log.
I was in South Riding, VA on September 7. I found translator 104.5 W283DG Sterling, VA, a recent sign-on and new signal that I had hoped to log at some point, relaying nearby 1500 WFED’s Federal News Radio programming. Since South Riding is only 21 miles NW of my home, I added W283DG to my FM DX Log and its screenshot to my RDS/HD Radio Screenshots gallery.

In the early morning hours of September 8, a very brief, but strong, tropo duct brought in New York, NY’s 92.3 WNYL, 97.9 WSKQ-FM, 101.1 WCBS-FM (under local WWDC), and 102.7 WNEW-FM at around 225 miles away. Trenton, NJ’s 101.5 WKXW also briefly came in over local WBQB with HD Radio at 177 miles away. The furthest signal received during the opening was previously-logged 99.9 WEZN Bridgeport, CT, at 281 miles.
During this opening, RDS from 97.9 WSKQ-FM and 102.7 WNEW-FM decoded for the first time on my radios.
I also added a new HD Radio screenshot from 101.5 WKXW.
96.7 WCEI-FM Easton, MD, a common visitor on my FM dial at 64 miles away, is now running RDS. I first noticed the signal, which turned on HD Radio earlier this year, running RDS on August 27. The screenshots below have been added to my DX Logs pages.
Minor tropo enhancement during the early morning hours of July 11 brought in the usual summer signals from Norfolk, VA and the Eastern Shore of Maryland. A few signals from coastal New Jersey were in, too. What made this opening different was that I received HD Radio for the first time from two previously-logged signals.
I first logged 92.1 WCDX Richmond, VA (3 KW, 74 miles away) on 5/15/00. Although I have received RDS multiple times from the station over the years, HD Radio was always out of reach, given the two frequencies WCDX has IBOC sidebands on are occupied by local 91.9 WGTS and semi-local 92.3 WERQ. For the first time, WCDX’s 92.3 sideband overpowered WERQ and resulted in a decode:
This one surprised me. At my home, 97.1 is occupied by local WASH Washington, DC, (17.5 KW, 21 miles away). I have received a handful of other signals over WASH over the years, but WASH is usually too strong to be overpowered by another signal. WAVD Ocean Pines, MD (4.6 KW at 115 miles) has overtaken WASH on a few occasions over the years. I first logged the station on 6/24/05, when it was WQJZ “Smooth Jazz 97.1.” On June 11, I received WAVD with RDS strength over WASH. A few moments into tuning the station, WAVD’s HD Radio signal started to decode. I didn’t even know WAVD ran IBOC.
I also added the following screenshots from the following previously-logged stations:

Long distance FM enthusiasts are always watchful for better ways to authenticate station reception to cement the credibility of their loggings. Radio Data System (RDS) is one way to do this, providing the received stations are equipped with an RDS encoder. Sadly, not all FM broadcasts feature RDS, illustrated below. Prevalence varies with the continent the listener resides in.
