Qodosen SR-286 1100 mi from the kitchen!

- Some surprising distances with the Tecsun AN-200 MW Loop. So I thought I would record them almost as evidence. It seems different people are getting different results with the Qodosen SR-286. The lower end of the MW band was warming up tonight. I got to San Francisco from Central Alberta (1094 miles). That's pretty good.

Very good receptions with the Qodosen SR-286 and the Tecsun AN-200 MW indoor passive loop. Good video. Have a good weekend.
Excellent. Glad you liked it. Thanks!
Awesome! That antenna does such a great job, i recently discovered the joys of it! Have fun
Yes, it couples with the radio's internal antenna rather well. Thanks. You too.
I manage to pick up CFZM most nights, even though it's 407 miles away. That's via the Carver antenna I built myself.
Home brew is perhaps some of the most fun part of SWL.
I have one of those "double station" frequencies in Pennsylvania. 1010 WINS, NYC in one direction and 1010 CFRB, Toronto in the other. It's always fun to turn the radio to change the station.
I often hear more than one station on a channel, but it is so gratifying to be able to differentiate them so clearly and easily. It's a nice feature of loops (and transmitters perpendicular to me).
I bought one of these radios yesterday. Let the fun begin soon.
Nice! I hope it cracks open the air waves (both ground and sky waves ;) ) to all manner of stations and transmissions for you.
What a great way to position your radio. I'll have to try this.
Sometimes the simplest solutions are best.
Impressive!
It has been a great little radio.
Too good kitchen radio : )
The little loop really helped with signal strength. I was pinning the meter, getting 99 dBu, with "local" AM stations on daytime power from Camrose (76 km) and Calgary (200 km). I don't know whether to be gobsmacked or dubious.
Good idea with the rubber band. Waiting for my 18650 to arrive. What 18650 battery brand are you using?
It was funny. I was thinking of fancy 3D printing options... and then the mock up elastic band just solved the problem. And the SR-286 is light and small enough to get away with it. As for the battery: just a no name. But it is wrapped exactly like my XHDATA battery -- so I wonder. It was pretty much moot anyways, as I had little to no other button top battery options even on the Jungle Web. I didn't want any of those USB-charged version of the 18650s. Some say the larger city centres have options, which I would suspect is true, but don't know. Where did you order yours?
Have you used a cable between the two yet ? I did have to look at the time you did this and it makes sense. Thanks.
Yes, I have used the mono 3.5 mm interconnect. I found the proximal coupling more effective. I'll look again and see if there is something there. I have found the long wire so much better.
Amazing, and they can't even get a hi tech iPhone to reach more than 2 miles.
The infrastructure dependency is significantly greater for cell phones. "the typical coverage radius of a cell tower is only 1 to 3 miles (1.6 to 5 kilometers) and in dense urban environments, a cell phone tower usually reaches 0.25 miles to 1 mile (0.4 to 1.6 kilometers) " (Source: dgtlinfra.com/cell-tower-range-how-far-reach/)
Last night on my PL-880 I picked up:
KXEL 1540 Waterloo Indiana (2460km);
KMOX 1120 St Louis (2355 km); and
KRLD 1080 Dallas (2557 km).
@@RSears I'm in northern California and been picking up RNZ in New Zealand on shortwave loud and clear and pretty much nothing else. I think my long wire is too long.
Antennas are black magic. Well, not really, but the success of even the greatest radio depends on them. And there is a whack of atmospheric conditions in play.
On MW I got the above-mentioned stations with just a Tecsun AN-200 loop coupled with the ferrite antennas in the Qodosen SR-286 and my Tecson PL-880. They both were essentially the same. That was interesting.
MW is different than SW, but being somewhat new to this, I haven't been able to get outside to compare different antennas. The SR-286 can bypass the internal ferrite antenna and use the ext antenna jack, which is amplified. I'm hoping it will provide a good means of contrast to compare antennas.
My XHDATA AN-80 is just a 7 m reel wire. I've got NZ by hooking it up a tree, but didn't have my 7 m fishing pole to compare whether a vertical position of the same antenna would help with sky wave reception. With reception verticality doesn't always matter. A Loop-On-The-Ground apparently works too. I'm waiting for warmer weather to get outside to compare these antennas.
I feel your pain 🙁 but trial and error is /will be my approach. A roll of decent silicone-wrapped wire is cheap. Get a two-pin 3.5 mm pig tail connector and cut and splice your way to success 😁
