Mine is around the world in two directions. When receiving fax by radio there is a sync bar. When a signal travels in the long direction there will be two sync bars. This is due to speed of radio signals.

How about satellite reception? 23,000 miles.

Actually I am sure you are talking about AM broadcast band. I received a Louisiana station while living here on the West coast, 2000 miles.

I would say driving home from a college class listening to WWL 870 New Orleans after hurricane Katrina at about 1190 miles. I was able to listen to it as if it was a local daytime station. I dont know if they went to higher power or went non directional but I havent been able to receive them that strong ever since.

I haven't looked up the distance, but from East Syracuse, I heard WHO in Des Moines, Iowa on a Buick car radio modified with an AC power supply, a longwire antenna, and a Mouse trap.
Heard KMOX on a Toshiba micro radio, and Louisiana on a Motorola Pixie, both without an external antenna.
My dad had a CB (back in the early 1960's). It was a Philmore kit, and the antenna was an 18" long coil of #12 wire mounted on the roof of the car. Someone supposedly heard him in England. On 2M, he QSO'd with the space shuttle.

There was a rumor that someone in Germany heard Cousin Brucie.

My longest non-shortwave DX would be Radio Rossi 279 kHz, heard in December of 2009.

In May of 2009, I was in Bocas del Toro, Panama, and I was able to hear a variety of expanded band stations from the Southern US on a Walkman radio. This was possible because the expanded band is not used in Central America. Frequencies in the regular AM band were covered up either with a mix of Central American stations or jammers (1500 kHz was really bad).

I guess if it counts I have received the CLB non-directional beacon on 216 kHz in Wilmington, NC many times using a 40M dipole. I understand its not a "typical" low power NDB. One of my weird hobbies is trying to receive these stations.

I have yet to actually receive LF broadcast below 500 kHz but Im told it can be done.

I'm guessing maybe 15 years ago I was into ATV, Amateur Television. I had about 60 watts at 439.25 MHZ and a 16 element horizontal beam. During an "inversion" where 2 layers of air do a quick flip it sometimes opens up the VHF and UHF bands, I was able to trade video with a guy down in Arkansas. I forgot which city but I have a QSL card laying around somewhere. I'm up in Milwaukee WI. The trip was about 700 miles or so which is quite a feat because video needs more power for a clear contact compared to other forms of transmission. After the contact was over some other local ATV guys were saying my contact beat the previous record. Later on I was able to verify that. But about an hour after my contact some guy in Ohio traded video with the same guy in Arkansas and beat me out by about 30-40 miles IIRC. Oh well, I was a local hero for about an hour. 8)

Of stations that had identification in English, Germany to California. MW band on an RBC-1 with very slight signal fluctuation. Probably a powerhouse station.

On BCB my longest has been Buenos Aires, Argentina - 3650 miles - but with a commercially made receiver. However, I was able to catch two Brasilians on my crystal set at 3077 and 3109 miles.

Here's an audio clip of the Argentine station.

That is entirely possible. In 1973 I was working at an AM daytimer in the Springfield, MA market. We completed a repair to the antenna system in the wee hours of the morning, and took advantage of the experimental period (midnight-5 am local time) to fire up the 5 kW transmitter to test our work. We spun a few records with IDs and requests for DX reports between songs. The farthest DX report came from West Germany.

From my current location in Hillsboro, OR, I think that the farthest MW DX I have heard was KRLD Dallas, TX when our local station on 1080 signed off for transmitter site work. In my recollection, they were adding diplexers so that a 910 kHz station could be co-located.

This week, I heard XEUT from Tijuana, which is 952 miles away. They only broadcast 1kW at night. The signal was mainly fighting interference from neighbors' TVs, rather than co-channel stations.

after all these years with some super antennae and ground systems built, what i can't understand is how i can *regularly* hear trans-atlantic AM/broadcast band/ mediumwave DX along with Saudi Arabia on 1521 kcs, but i can't hear anything further west of the mississippi.

the furthest domestic AM DX that i heard at night was Des Moins on 1650 kcs years ago. the powerhouses out of denver, OKC, KC, the dakotas, texas, NV and the like have never been heard here.

KMOX is the furthest domestic AM DX that i can do, but yet, Algeria, Morocco, Saudi Arabia, Libya, Norway (back in the day), spain, Mauritania, and other Euro, Middle East, and N.Af countries were regularly heard.
