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.

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... BigHustle fucked around with this message at 19:04 on Jan 14, 2010 |

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 have a quick question as well... I put up a 46 foot run of speaker wire in my room to act as an antenna until the spring thaw hits and I can put up something on the roof. When I tune in WWV on 5000 khz, I'm also able to hear the woman from WWVH speaking her time announcement right before the male WWV voice kicks in. It's faint but clear and audible. Does this mean I'm actually catching the WWVH signal coming out of Hawaii, or is it something also coming from Colorado? For a distance reference, I'm in New Jersey.

Dijkstra posted: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. 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. This may help: http://www.aa5tb.com/efha.html

Doc Faustus posted: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? 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.

Still, they're a lot of fun to play around with. I enjoy it a lot. I'm about 36 miles from Newark International Airport and can occasionally snag some traffic from flights passing overhead, but those are far and few between. Some air band radios pick up massive interference from FM radio in the area too. My G6 is terrible about FM bleeding into the air traffic frequencies.

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

JammyLammy posted: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. 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.

JammyLammy posted: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, 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. code:

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.

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?
