I am going to set up a rig to start DXing, and getting my technical license. My plan is to buy a Kenwood TS-590 SG transceiver and a discone antenna.

My home’s previous owner had satellite TV, and my question to you is, can I use the existing cabling for my antenna?

There is a connector in my living room, and the cable runs to the connector/splitter box for the dish. Could I run a cable from the end of the existing cable at the splitter box, to the antenna?

I’ve attached some pictures to show you what the existing cables look like.
Picture 6 has a circle drawn on it to show where I’d like to mount the antenna.

I remember back when I was 9 or 10, laying under the covers at night slowing turning my AM transistor radio dial and seeing what I could pick up. It was a thrill to hear stations from Chicago, Cincinnati or Little Rock. I look forward to the same thrill listening to voices from across the country and around the world……

Thank you for your time, and for the wonderful website.

Thank you, John, for your question and for the kind compliment!

I’m publishing this question here, though, in hopes the SWLing Post community can help you. I have very little experience matching antenna impedance this way especially when transmitting will be involved–there will be a mis-match, I’m pretty sure. With that said, I know many mag loop receive-only antennas actually use RG6. It would certainly be great to use an existing penetration for this application.

Post readers: If you can help John, please do comment. Quite frankly, this isn’t the first time I’ve been asked this question, so I’ll follow comments as well.

John, I’m sure you’ll soon have your radio on the air receiving the world just like when you were nine–or even better! Great choice in that Kenny TS-590SG–it has a brilliant general coverage receiver for broadcast listening!

Ed gives this Realistic DX-440 a bath!

Many thanks to SWLing Post contributor, Edward Ganshirt, who shares the following:
I found this critter [a Realistic DX-440–see photo above] at a flea market. At first I pondered as to when I had my last tetanus shot before handling it, then again it had something that I see rarely in these portable radios … a BFO..!

I always said that a shortwave radio without a BFO is like a Harley-Davidson with a top speed of 25 mph, so I bought it. On the way home I could smell a barnyard aroma. I ruled out chicken and hog but I think it could have been sheep or goat. So I decided to see how well it works. It took a little bumping around with loose connections to get it working. But first since it was going to be taken apart to service the case and knobs would get a nice hot bath in a sudsy ammonia citrus cleaner with a bristle brush. Also the PCB’s would get brushed down with a mixture of denatured alcohol and acetone.

Now for the hard part: finding the rickety connections. This turned out to be simple, just inspect each wire at attachment point. I found 3 broken wires that were re soldered. Now it is together I am looking for a 9 inch antenna. The one here is not original it extends 66 inches.

As to it’s performance, This Hogg can go up to 75mph now that I have the plug wires on. The user interface speaks to me as a lab instrument more than a daily listener which I think will become its role.

Absolutely amazing transformation, Ed!

I’m especially pleased to see you’ve given this level of TLC to a Realistic DX-440. I regret having ever sold mine as it accompanied me across the ocean when I studied in Grenoble, France, for a year just after high school.

The DX-440 and I did a lot of travel and a lot DXing together! I hope your DX-440 takes you across the globe, Ed!

September 13, 2017: Update from WRMI–9,395 kHz on air at low power

2 Replies

Many thanks to Jeff White, at Radio Miami International, who writes with the following update:

Florida Power & Light Company has announced that most customers in our part of Florida should have electricity restored by the end of this coming weekend — that is by Sunday, September 17. So we hope to be back on the air here at WRMI by that date or before.

Meantime, we have one frequency on the air at very low power using our generator: 9395 kHz. This will be on 24 hours a day with regular programming.

We are making repairs in the antenna field so that by the time electricity returns, we will be ready to resume our full schedule of operations.

Jeff White

Thanks for the update, Jeff! We’re all so happy the WRMI crew made it through Hurricane Irma safely and happy to hear you may have power as early as this weekend.

We’ll publish all of Jeff’s updates here on the SWLing Post.

No power, but radioactive–!

My CommRadio CR-1a, with an internal lithium battery, is the perfect off-grid radio companion.

Monday night, the remnants of Hurricane Irma moved through western North Carolina. Because the SWLing Post HQ is at a high altitude compared with the surrounding area, we received higher than forecast winds. Still, we made it through fine and feel pretty darn lucky.

Yesterday afternoon, even though we maintained power throughout the storm, the utilities company cut power to our road due to a tree that had fallen on a pole that also supported a transformer. It’s a tangled mess. Since there are about 17,000 without power in our rural area, it’ll be some time before power is restored to our road–likely late Friday evening or sometime this weekend.

Loss of power isn’t a major problem for us since our refrigerator and freezer are off-grid and solar powered 100% of the time anyway. We also have a propane stove to cook on and plenty of charged battery packs and flashlights (and at least half a dozen HumanaLights in service).

On the plus side? Even though our house is pretty RFI free, when the power is cut, it’s amazingly radio quiet.

I listened to RRI last night on the CommRadio CR-1a (see above). Later, I sat in bed with the pilot run CC Skywave SSB and tuned through the 31 meter broadcast band, the 40, 80 and 160 meter ham bands and the mediumwave broadcast band. Happy to say that the Skywave SSB did an amazing job–and propagation was decent. Reception was so good, it felt like I was camping in a national forest. Just makes one realize how all the devices in our home add to that RFI noisy environment.

We count ourselves lucky as news from all of the areas that took the full impact of Hurricane Irma is simply gobsmacking.

This morning, I listened to a few HF nets on the 80 and 40 meter bands with the Digitech AR1780–I noted no less than five hams reporting that they were operating on generator power. I believe this hurricane has caused one of the largest power outages we’ve ever had in the US due to a natural disaster.

Note that since I don’t have power at home, I also don’t have Internet service–keep this in mind if you attempt to contact me this week. I will post quick updates to the SWLing Post while I’m in town, however I will certainly fall behind on correspondence. Thanks for understanding.
