[QUOTE=Boombox;2824537]^^^^^^ Yes and no. I've been using the same indoor antenna since 2011, and used to pull in a *lot* more SW than I do now. Especially Radiobras (Amazonia) -- conditions had to be abysmal for it not to come in.


What indoor antenna are you using?

Fantastic conditions here on a Sunday morning-a shot of the good old BBC transmitting at a little over 11,000 miles from Talata-Volonondry, Madagascar on 12095kHz. I love Winter propagation!

What indoor antenna are you using?
It's a 25-30 foot wire that is folded back on itself and runs in a rough L, in the second story of the house. So It might be longer than 25-30 feet... But that's probably its effective length. I put it up after I began to get re-interested in SWL and Ham listening in 2011. On SW I've used it with my DX-398, 390, and 440.

PS Sorry for the late reply... Didn't notice it until just now.

Voice of America in English & Korean. 9975khz Target: Korea at 2030UTC. Clear skies here, about 250 south of Anchorage. Best signal quality I've heard in a year.

Nice catch! Getting it here too @ +10-+20 over 9. Transmitting from Udan-Thani, Thailand. 15580kHz VOA is also strong from Botswana at 2042UTC. s7-9.

Started the morning on RNZI with a good signal into central Ohio on 7425. With the rain, my noise floor was down about 20dBm and my QRM less than 95% of normal. Love the rain.

I've been receiving radio saudi from riyadh pretty well here in northern indiana on 13710, 15205 and 15435 during the day. About a month ago I installed a new mini whip outside on the south wall of my office building and i'm very impressed with how well it works.

Elaborate upon the "mini whip" brand so others know exactly what antenna impressed you they may want to get one too!

I don't know if it has an exact brand name but I purchased it on ebay from a seller in London. He sells both assembled units and kits you can put together yourself but it appears his assembled listings are out of stock right now. If you search for "IP33 mini whip" you should find a listing for it.

Here's a link to his website. On that page is a link to a document that describes the specs and has some assembly instructions.

OE1GPA mini whip

The entire setup consists of this mini whip connected to 60 feet of LMR 195 that goes back to my office about 40 feet away. As most of you probably know these antennas are very susceptible to noise and it took me the better part of two weeks to find a setup that worked well. Inside it did not perform well at all but I wasn't surprised as the building is covered in steel siding on all sides. I ended up putting it outside on the south gable end of the building just mounted on a wall mount about 13 feet above ground.

I still had a lot of interference traveling back to the antenna on the coax so I had to address that as well. I ended up running the cable through a ferrite core about eight times where it enters the building and then again three times in the office where it connects to the receiver. The difference was night and day, the noise floor is nice and flat now. I do think the steel siding also helped in keeping interference inside the building away from the antenna.

This is all connected to a $20 version 3 rtl receiver running in direct sampling mode. It works better than I thought however there are a lot of spurs everywhere and the signals are aliased above and below 14.4 mhz. This is just due to the rtl dongles sampling at 28.8 mhz. I did order a proper HF receiver last night, I wanted to wait until I got everything sorted out on the antenna side.

That's great info! One more thing, if you would, can you specify what ferrite core (composition) you are using? This would complete the picture for those who may want to give your setup a go Thanks!

The ferrite close to the antenna is a fair-rite model 2631626202. It’s a 31 mix that’s 25.4 mm inside, big enough that you can put about eight turns on it with the 195 cable. Inside the office at the receiver I transitioned to about two feet of lmr100 and a fair-rite 2631102002 12.8 mm inside diameter ferrite. It’s just the right size to get three turns on it with the lmr 100.

I ordered these from mouser and you do have to pay shipping but if you order multiples or other things it’s not too bad. Some people have luck with the ft-240-31 ferrites but in this case I had too much interference and needed the bigger one. It’s quite impressive how much interference there is in a house / office!

Thanks for all this. Honestly I personally needed to know about the ferrite cores-I might get them for my Wellbrook.

Logged and recorded Radio Saudi on 15170 - short video of it posted on YT at https://youtu.be/wsGsgLGfkKA

Probably my longest DX copy, was solid reception for almost an hour with no fading - logged several others on the same band but this is the furthest one of the bunch so I wanted to share it

Caught another DX out of Madagascar at just shy of 11,000 miles from here. KNLS World Christian Radio in Arabic at about 2030UTC, about 1:30PM my time.

13710 is the same frequency on which I hear BSKSA in Riyadh, Saudi Arabia during the morning hours here. Riyadh is 11672 kilometers from me, which works out to 7253 miles. I wonder if BSKSA is actually relaying through Madagascar, or vice-versa. They both broadcast in Arabic targeting North Africa, Madagascar is a lot further from my location. I did hear Radio Feda in Madagascar last year, but haven't heard them recently.

BTW, could you please include the frequency in your text when you post a logging? Running YouTube videos while logged in to this forum can really bog down a browser sometimes, depending on the speed of the computer and the connection. On my end, sites that use lots of JavaScript often slow things down considerably. My computer is 7 years old, and I don't have the fastest internet connection, either, as it's far too expensive. I have broadband, but with one of my ISP's cheaper packages. Of course, I can't speak for the other users.

Sorry about that GB46. Will-do I usually do for the most part but sometimes I forget and shouldn't assume the video will speak for me.

Thanks, ridgescan. It's a nice video, nonetheless.
