I'll be adding a bit to the cash totals in a month or so.

I'm moving soon, and my new landlord said it's cool with him if I put an antenna up on the roof. He said that there's an old TV antenna up there, complete with coax. Do any of you think just hooking up to the TV antenna will be any good, or should I replace it with something else?

Chalk up another $90 to the financial damage totals.

I picked up a RadioShack DX-394 this afternoon from a coworker. I figure it'll work to get me started, although Google searches now make me want to mod the gently caress out of this thing. I plan to start listening tonight.

You may as well tack on another $90 to the total. I'm sending my DX-394 halfway across the country to be modified into something useable by Lowbander. He's going to do all the mods on this page with the switchable IF mod rather than the Kiwa filter.

During it's absence, I plan to put an antenna up on the roof. The landlord doesn't care as long as it's not an eyesore... Any recommendations? I'm in central Jersey in the middle of town, no large buildings around.

I'm thinking about picking up the Grundig G6 as a foray into the mysterious world of shortwave radio. It's $92 right now on Amazon, and $75 from L.L. Bean.

drat you... Add another $75 from me as well. I was up in the air between the 7600GR, the G6 and the G3 until I saw that price.

Finally, a simple question: is shortwave dead? This article probably isn't doing much for shortwave radio sales.

It may be true that some international stations have stopped broadcasting in recent years, but you still have the crazy preachers who won't go anywhere as long as they can keep paying the power bill. Just tonight on 7050 I was listening to a preacher using shortwave to cast out the demons that had entered the listener's bodies from such sources as prescription medicines, hearing people talk about other religions, and listening to Elton John's back catalog.

I was almost a believer until he wanted to cast Unicron out of my body. That was the last straw.

I finally caught my first voice numbers station broadcast tonight.

I've run across M8 a few times while scanning, but caught V2a tonight broadcasting on 5880 KHz. I'm assuming the transmission started around 7:00 UTC since it ended around 7:45 UTC. I missed out on the beginning, but did manage to catch the end.

Many thanks to Wasabimilkshake for posting that link to the Grundig G6 on sale over at L.L. Bean. Picking up that thing was the best purchase I've made in a while. I was concerned about it being too sensitive since I live in Jersey and have to deal with overpowered signals from both NYC and Philly, but even without an external antenna I'm getting more than I was with my old DX-394. Last night I was able to catch VVW on both 5000 and 10000 KHz, which has never happened before. I was also able to catch the English broadcast from Voice of Turkey with minimal interference.

I posted back in the day that I was going to send my DX-394 to Lowbander for modification, but it never made it out. I'm now kicking myself since the lousy reception I've always had was completely due to the lovely way RS made the first version of that thing. Tonight when I hooked my slinky dipole up to the DX, I could barely hear V2a on 5880 since there was massive bleed-through from the fundie preacher transmitting on 5890. Meanwhile, the G6 was sitting not 3 feet away, happily spitting out Spanish numbers just using the built in whip antenna.

EDIT: Maybe some of you can answer this for me... I've noticed that on the G6 the 'Auto Search' feature likes to jump past large chunks of frequencies (e.g.: 26150 - 30000, 150 - 2400, 3400 - 3900) that are manually tunable. Researching some of these 'blank spots', I see that they are listed as 'fixed service', 'aeronautical mobile, 'maritime mobile', or 'government use'. Some of these are obviously not going to mean much to me (I doubt listening in on the Forestry Service from 29700 - 29800 is very exciting), but some of them would be nice to scan through on without having to do it manually. Do any of you know if there's a way to turn off the filter that skips these when auto scanning?

EDIT TWO: Eton/Grundig replied to my email. The auto search skips over anything that isn't a 'major shortwave broadcasting band' and there is no way to configure it to scan all frequencies, so manual tuning is required. Looks like I will be getting the DX-394 modified after all...

I have the G6 and have been very pleased with it so far. In my place (second story apartment in a house in the middle of Jersey) I get better reception with the built in whip antenna than I do with the random wire I have strung up, but that's because I haven't built a properly tuned antenna yet.

If you're in/near a major metro area, be prepared to catch a lot of FM interference when running through the air bands. It may not be much of an issue if your local airports are running at frequencies that aren't a harmonic of the local stations.

SSB is fantastic on this thing although it just has an SSB button; It doesn't differentiate between USB and LSB. When in SSB mode you can tune either by 1 KHz steps in 'fast' tuning or smaller increments that aren't listed on the display in 'slow' tuning so you can really dial in the signal.

I haven't used a G3, so maybe one of the other Goons can help with a review of that one.

EDIT: Got beaten to the punch on the G3 commentary.

A dipole by definition has two balanced radiators, each of which are 1/4 wave long. Each radiator is connected to a separate conductor of a dielectric or parallel line. Both ends of the dipole aren't connected to the same conductor. For example, if you feed a dipole with coaxial cable one radiator is connected to the center conductor, and the other is connected to the braided shield.

A random wire antenna has only one radiator, which is connected to one side of parallel or dielectric line. The other end of the dielectric or parallel line is usually grounded, or connected to some kind of matching network. A random wire antenna is electrically fairly similar to a vertical antenna in a basic sense. It is just laid out horizontally.

In your example, the random wire would still be a single radiator, just connected to the feedline in the middle. So it electrically it would not be a dipole.

One other thing to remember is that in a dipole, since the system is balanced the length of the poles are exactly what you put up. In an end fed setup, the feedline is part of the antenna unless you use a balun to 'terminate' the connection at the feed point.

Examples

60 foot dipole: Each 30 foot arm is connected to a feed point that connects to 20 feet of coax running to the radio. Your antenna is 60 feet in length.

60 foot end fed: You have a 60 foot run of wire connected a feed point that connects to the center pin of 20 feet of coax running to the radio. Since there is nothing for the ground to connect to, you have essentially have a 80 foot antenna.

OK, hopefully last dipole-construction question. Is the use of coaxial cable an actual important part of the design, or is it just popular because coax plugs directly into so many amps/tuners/radios? If there is some special property of the coax, can I replicate it by using a resistor with the proper ohms in lieu of coax?


tl;dr: Frys Electronics didn't sell the dojigger to easily connect 2 wires to a coax cable.

It's mainly used because it's plentiful and easy to work with. You could always solder the ends of the wire directly to the coax (one side to the center pin, one side to the braid) instead of using an adapter and waterproof it (wrap the joints in electrical tape and encase it in a T of PVC pipe with the ends caulked) if you're doing it outside. If you're running this inside, you could skip the waterproofing.

EDIT: Or since you're going to end up plugging it into a 3.5mm plug anyway, do what I did and run to RadioShack, pick up a bare plug with screw terminals for about $6, and just attach the wires to the plug.

I just a shitton of static. How would be the best way to go about reducing this?


edit: I set up a bunch of cable around the ceiling. When I clip it to my antenna, it seems to increase the amount of static....

edit: Listening to the statics sample on the first page, it sounds like power line static. If I was to run a cable far away from here, set up a long antenna, would that help reduce it?

If you're using a random wire setup, there's really nothing you can do other than to make sure your wire isn't running close to power lines. If you run a longer antenna and clip it, you'll end up with the same problem if your new run is crossing/running parallel to power lines.

One other thing you can check out is whether you have anything electronic plugged in around where you are. If I plug in my netbook I get a boatload of static on a random wire clipped to my G6, but if I disconnect the AC and run it on battery the static goes away.

Excellent, thanks for the help. I did a really ghetto ceiling antenna and moved the radio away from alot of electronics, that cleared up things alot. Manage to hit some Chinese station and right now I have it on a Japanese station. The chinese one came in quite clearly, the japanese has a bit of lingering static in the background but you can still hear the broadcast.

I still got another 100 feet of cable, I'm debating about putting that up (will need to pick up some hooks). At some point I wouldn't mind start filling in those report forms to send to stations. Any good links on how they should look, and where to send them to?

If you're in the US, you may be hearing Radio China International being broadcast out of Sackville in Nova Scotia. A few nights I've been able to pick up Radio Algerienne broadcasting Quran calls out of Issodun in France and Voice of Russia being broadcast out of Kishinev-Grigoriopol in the Republic of Moldavia, but most of the usual suspects are being broadcast 'locally' by Radio Canada International (China Radio Int., Radio Japan, Voice of Turkey) out of Sackville or by WYFR/Family Radio (Radio Taiwan Int.) out of Okeechobee, FL.

I generally keep the netbook handy and use short-wave.info to see what I'm listening to and where they're transmitting from. For the rare occasion that they don't show anything there, I'll Google the frequency and usually something will pop out at me.

As far as the antenna goes, you might want to figure out what frequencies you want to focus in on and make a half-wave antenna (or several) to fit the bill. The basic formula for determining your antenna length is to divide 468 by the frequency in MHz. As an example, if you want to listen to Radio Habana Cuba on 6000 KHz (6 MHz) or stations on nearby frequencies, you'd want to cut your wire to be about 78 feet long. Antennas also work on multiple frequencies, so that antenna for 6000 KHz will also work (although 'not as well') on 12000, 18000, and 24000 KHz.

As far as QSL info, I haven't gotten into it so I'm of limited use there. You can get general info on what the radio stations look for here.

I'm more interested in exploring up and down the spectrum seeing what I can get, rather then trying to find that particular station. This is a stupid question, but would this be feasible,

Cut one antenna at 78 feet for 6000 KHz (and 12000,18000,24000, etc)
Cut another antenna at ~94 feet for 5000 KHz (10000, 15000, etc)
A third at ~59 feet for 8000 KHz, etc.

You get the idea. Basically cut several different lengths, hook them unto the radio antenna (not touching each other!) Or would having them without proximity of each other mess it up?

Depends on what you're using for antenna wire. If you're using speaker wire or something else covered in a non-conductive shield, you should be OK with them being close together. If you're using bare wire, you want to make sure they're separated enough that they won't touch at all.

If you just want a ghetto antenna and aren't concerned with looks, you can make a homebrew separator out of some straws by cutting a length of straw long enough to leave an inch or 2 between the antennas and cut holes in the straw to hold the wire. Put a spacer every foot or so to keep things nice and even and you're good to go.

AMANDX, the guy who made those limited space antenna pages I threw in a few links back, has a page with dipole instructions and an example of a dipole antenna he made in a similar format using PVC pipe as spacers that has a 80 foot wingspan.

That could be it. The frequencies used by CODAR are within the range I was picking up odd noises on. I live on the east coast so that might explain why it comes in so loud and clear.

The multiband radio is enough to hold me over until I can save up for a brand new digitally tuned radio with SSB and all the goodies.

Better ways I can improve my speaker wire antenna?

Basically radio is next to window, a long (~40 feet of speaker wire) is attached to the antenna using an alligator clip. The wire goes out the window, then up to a window in the attic, where its just ducktaped to the wood beams in the ceiling. Wire is going inward into the attic.

It boosted signals and I'm actually picking up things from inside the house, however I'm getting TONS of interference, its very hard to get just one station coming in when I'm getting static and stations from other freq. bleeding in.

What can I do to improve this?

If you're using a random wire antenna, really the only things you can do to improve the signal quality are to make sure that your antenna isn't grounding to any metal, make sure that it's not running parallel to any power lines, and when listening to the radio make sure that you have any fluorescent lights or anything with a power supply is away from you. I know I had interference with my radio when I had the lights on or had my netbook plugged into the wall and nearby.

Send lawyers, guns and money
The whale poo poo has hit the fan

Send lawyers, guns and money...

It was either that or 'Symphony of Destruction'. Warren seemed the more obvious choice.

Alright, goon project this weekend.

A good source for the variable capacitor listed in the instructions is a thrift store like the Salvation Army or Goodwill. Grab an old AM clock radio with a dial tuner and you should be good to go.

That explains why it was coming in with a strong signal. I guess googling frequency isn't the best way of getting station id's. How do you figure out stuff like that?

I use Shortwave Info. You can search by radio station to see when broadcasts take place or enter a frequency to see what's broadcasting at that moment in time. It's nice since it shows you the frequencies around what you searched for as well as shows a map of the transmitter locations.

Most of the foreign broadcasts I picked up when I was living in Jersey were rebroadcasts coming out of Radio Canada's Sackville, ON transmitter site or Family Radio's Okeechobee, FL transmitter like Radio Nowhere mentioned. The only exceptions I really came across were Radio Havana coming out of Cuba, the Atencion numbers station also coming from Cuba, and a station (Radio Algerienne, maybe?) that was broadcasting Quran calls out of southern France.

As an aside, I was thinking about building a magnetic loop antenna and hanging it from my ceiling on some sort of lockable swivel instead of taking up floor space with a clumsy tripod base. This bad picture hopefully makes a small bit of sense:



Am I overlooking something painfully obvious (besides some dumb flaw with the diagram in regards to the antenna design that I pulled from my shoddy memory). It would be up higher, making the tuning knob maybe a little awkward to get to, but workarounds would be simple so I'm not concerned with that. Mainly just saving floor space.

I was going to do the same thing before I moved. I planned to mount it to my ceiling above the bed on a hinge of some sort since I did my DXing while in bed. I'd do it here, but I'm in the basement so I don't think anything but an outdoor antenna is going to be of much use to me.

Maybe one of the folks who already built one can answer this, but is there any reason you couldn't mount it 'upside down' and have the capacitor at the bottom and coupling loop at the top? You'd need a little extra coax, but that's better than needing to get a stepladder every time you need to retune.

On 4870khz, midnight eastern (4:00 UTC (?)) Hearing just this beeping noise, my friend says sounds like a monotone toot from a panflute. Nothing else but a steady beeping. What is causing it?

Are you near the coast? It could be CODAR interference. I used to pick that crap up all the time when I lived in Jersey. If you're far enough off, you may just be receiving signals from one of the transmitters instead of all of them.
