In June 2009, during the "Nightlight" period of the US analog to digital transition, most of the TV stations across the US had already vacated the Lo VHF band with a few remaining nightlight stations only running transition promo loops. I did some DXing from where I then lived in Carbondale Illinois which is almost exactly in the middle of the Continental US. This is what I received in mid June 2009. I captured video clips of their IDs on my cell phone.

The receiver I used was an unmodified RCA Victor TV model 8T243 made in 1948-49. I used a 50ft mast VHF-UHF antenna with rotator. The direction of the antenna position varied as the ducted signal sometimes curved along its travel:

CKCK Channel 2 Regina Sask. 2000km
CBAT channel 4 Fredericton NB 2000km
WGBH channel 2 Boston MA 1500km
WPBT channel 2 Miami FL 1200km
XEFB channel 2 Nuevo Leon 1400km
KRMA channel 6 Denver CO 1500km
KASA channel 2 Santa Fe NM 1600km
KPHO channel 5 Phoenix AZ 2000km
When I lived in suburban Cleveland, I received some almost unbelievable TV DX. It was in the summer sometime in the '80s, and the station I received on the color TV in my living room at the time was KWGN-TV, channel 2, somewhere out west, 2000 miles from where I lived at the time (I cannot for the life of me remember where the station was located, but it will probably come to me shortly after I post this). In addition, again in the eighties, I received some great TV DX using just the monopole VHF antenna on my 12-inch Sharp all-channel b&w portable TV. The station, again, was an NBC affiliate some 2000 miles away. I was at my grandmother's farm in Richfield, Ohio (between Cleveland and Akron) at the time, and the reception was almost unbelievably good while it lasted.

Unfortunately, however, since I moved to my current residence 21 years ago, I haven't seen any TV DX, since my TV is connected to Spectrum "streaming" TV service, without a cable box (I have been informed by Spectrum that, since I now have this service, I no longer have traditional cable, and so do not need a box). From this, I am thinking the cable operator may not be using traditional cable boxes any longer; however, this is just a guess, although with streaming cable, I am honestly not sure what is going on. I do know, however, that my charge for this service is just under $30 a month; it would be a lot higher, I'm sure, if I had a cable box. Being a senior citizen on a fixed income, this is welcome news, as I honestly do not want or need an additional charge (for a cable box or anything else associated with my television service) on my bill. The additional charges (two) on my cable bill are for Internet and home telephone service.
