I spent the $20 required at Radio Shack for 50' of speaker wire and the 1/8" antenna plug, soldered them together, and whoa. Huge improvement in reception, even with the wire just sitting in a pile on the floor. I'm going to run the wire out the window and put it up in a tree in my yard to see how that goes.

Also, some interesting beeping at 5898 KHz right now.

I do have a regular antenna, but I have an antenna plug in the radio for an external antenna, and when something gets plugged in there it shuts off the whip antenna.

I just tossed the length of wire up a tree, and the reception seems to have improved a bit more.

I'm not sure about your scanner; I just got this radio like 3 days ago, so I'm just following suggestions here.

bad mutant vibes: I usually do the opposite. I start on AM, and seem to be fairly good at picking out SSB stuff. I guess it just depends on what you're looking for.

Astro Zamboni: Thanks for the slinky antenna links!

I've been trying to read a little bit about building an antenna myself, but then I start reading stuff about baluns, and air-wound coax, and resonating at such and such a length and so many MHz, and hurrrrrr... :psypop: I'm not even sure where to start, so I've got my speaker wire out the window and up a tree for the moment.

That's been my only gripe about the E5, as well. No continuous scanning. But in a way, it's a boon to my listening, as it generally makes me slow down and pay attention while I'm scanning instead of occasionally zoning out while I wait.

I have to be honest: you guys sort of sucked me into this on the spur of the moment, and I had visions of regret after buying the radio. Quite the opposite has happened, though; I find myself looking forward to optimal scanning times and trying to figure out how to better route my antenna wire to higher spots, and taking a lot of pleasure even in just listening to some random hams talk.

This has really turned into a lot of fun.

Sat down, turned on the radio, scanned for about 10 seconds, and the Spanish numbers lady is in progress at 6768 KHz.

That looks like just the sort of antenna I need. I could probably do a short version of a long wire in my back yard, but I'd probably have tree issues, and we don't have a very big lot.

How much did you end up spending on parts? It looks like a pretty darn inexpensive project.

Leave me alone, dad, I'm with my friends!


I've been pricing things, and it looks like this project is going to be damned cheap.

Cheap-rear end radio: $5
PVC pipe: $1/foot or so ($5 worth at most)
Copper tubing: per the original builder, $6
Assorted nuts and bolts: $10, maybe?
Coax cable: probably free because we're all nerds and have entire spools of it lying around.

$30 or so. drat. And I already have some stuff to make a base with, so I don't even need that much PVC, if any at all.

It doesn't get much cheaper than that.

I'm about 2/3 of the way through building the magnetic loop, and it's all been straightforward stuff so far. All I need to do is finish soldering :argh: the wires to the main loop and the coax to the coupling loop, throw on a base, and go to town.

Also, total cost for parts (I had some stuff lying around): $21.06.

Man, I just can't quite pick out what he's saying. The signal is super weak here (Houston).

Overflow: I had the same question about what he did with the braid; I wound up just stripping the insulation off, unraveling the actual copper braid and then twisting it into a single braid, and soldered that to the coax. I got 5' of that #14 house wire and soldered it to the capacitor and then to the main loop. That poo poo is stiff as hell, so it was a pain in the rear end. HOUSE WIIIIIIRE :argh: I wound up zip tying those bastards down while I soldered, and just left the ties on.

The build went okay; aside from Houston being in the middle of a heat wave and getting bled dry by mosquitos in my garage, I didn't run into any problems. I've been using the antenna for a bit, and there's a HUGE reduction in noise from the random wire I was chucking up on the roof. I can easily hear signals now that aren't even registering on the E5's signal meter, although I did notice an apparent decrease in volume (I have to crank it up to 15 or so instead of my usual 7 or 8 to hear it sometimes). Probably just the fact that the new antenna is a.) on the ground, and b.) inside. I'll probably drag it outside to see how it does in the front yard.

Okay, I'm going to have to revise my prior statement about the antenna.

My 50' speaker wire tossed on my roof kicks it's rear end.

This $20 contraption that I spent 2 days working on decreases my reception, even on strong signals. I've checked every wire, every solder, every instruction on the guy's website, and my lovely spool of wire works significantly better.

For example: I tune into WWV at 10000 KHz.

1.) With the whip antenna, I get an extremely faint signal right now. I hear an occasional tick.
2.) With the loop antenna, I got a helluva lot less noise, but I can barely, and I mean BARELY, hear the signal, with the volume tripled over what it normally is.
3.) With my wire chucked up on the roof, I forget to turn the volume down and get partially deafened by the ticking and the announcer's voice, with very little noise.

What a disappointment.

Yeah, I actually thought that feed line connections might be the problem, so I snipped those off and made brand new connections on both ends of the line, and nothing changed. Any suggestions on how to make a more solid connection would be helpful; I just carefully stripped back the outer insulation to expose the braid and soldered the plug to the wire as best I could, then soldered the center connection to the middle of the jack. I guess it could still be a connection issue with the braid, but I have no idea how I'd make it more solid.

I suppose it could also be a dud capacitor, but that seems like it would be weird. I dunno what else to try. But I emailed the guy with the plan, so hopefully he'll have some ideas.

Do you notice any change in volume in signal or audio at all when you turn the knob on the capacitor? Also, can you confirm that you have a break in the copper loop where the capacitor is?

Honestly, I don't really notice any difference at all. However, I was using a station around 6600 KHz as my test station, and I was told by Alex (the guy who runs kr1st.com) that I should try something around 15000 KHz. I'm going to try that quickly here before I head off to bed.

There's definitely a gap at the top of the loop, at least 1/2" worth.

Alex said it could also be a capacitor issue, so Monday I'll probably swing by Walmart on my way home and grab another cheapo radio and do some disassembling and some more :argh: soldering :argh: I don't know why I can't solder well. It's a pretty simple task. It just takes me twice as long to get a good solder.

Are you having trouble with the solder on the copper pipe? You might want to give your soldering spots a light sanding on it. They have have coated it with something that's interfering.

The solder points on the copper are pretty sturdy, actually. I just have trouble soldering in general. Which is odd, because at work, I can start IVs on confused and struggling patients pretty well (with a little restraint help from another nurse). But hit a stationary target? :laffo:

I've been fiddling with this drat antenna, and I'm finally hearing some freaking tuning. I think I just need to make some adjustments to lower the limits a bit. The tuning is really obvious up around 25000 KHz, so just need to find the lower limit now. At least the freaking thing is working.

Overflow: One more question. I see you bought what was it, 25\' of the #14 house wire. How much of it did you use for the coupling loop? I bought 5\' and used just enough of it to make the 2\' circumference loop with a couple of inches at either end for connecting to coax (with a couple feet left over for soldering to the capacitor, etc.).

I wonder if making a multiple turn coupling loop would help? I\'m still not really noticing a drat bit of difference tuning.

I have the Sony, I'll list the things I like or discovered. Someone with the E5 chime in and tell me how many of these are shared.

- Headphone and line out jacks. If you listen to FM it gives stereo out.
- The synchronous detection mode is good on strong signals, it removes much of that atmospheric fuzz, but isn't that great at eliminating fade. On low-power or weak signals it usually serves to amplify the interference. If the carrier is a little off it also makes a horrible squealing when it incorrectly locks. It's controlled by a switch on the side, I only turn it on after I have found the freq. I want.
- Nice big keypad for direct input.
- Can scan remembered stations like a police scanner.
- Alarm clock?
- Ability to tell you GMT or any time zone with the touch of a button, even while listening.
- Charger not included, so I've been using the same alkaline AA batteries for the last couple months. Good efficiency. Built in speaker is also pretty good.
- Comes with pleather carrying case.
- Buttons feel like the microswitches will fail pretty quickly, but it's just a feeling. They don't make nice satisfying "click" noises when you use them.

Here's my take on the G5:
-Headphone and line out jacks, FM in stereo.
-No synchronous detection, but the whip on mine is superior to the magnetic loop I wasted two weeks on, so who cares? Excellent reception.
-Nice clicky keypad for direct input, and an intuitive layout.
-Speaker sounds pretty good.
-I don't think it scans remembered stations, but it has 700 memory spots.
-FOUR ALARMS so you don't miss any broadcasts of your favorite anti-government conspiracy freaks who transmit from their mom's basement.
-Ummmm... set your radio's clock to UTC and you're golden.
-Charges NiMH batteries internally (batteries are separate).
-Comes with a real fake leather case AND a wrist strap!

Plus, if you buy the Grundig G5, you can harass your wife while you're listening to it by doing your best Cookie Monster voice and going, "GRUUNNNNNNNNNNNNNNNNNNNNNNNDIG!"

On another note, I'm going to destroy this worthless magnetic loop antenna in a very violent fashion tomorrow. I swear to god my whip antenna picks up stations just as strong and with not much more noise. I don't know if I'm just lucky to live in a relatively low noise area, but poo poo on it. I've spent way too much time trying to get this thing to work and it's just not happening.

Now my wife is going to be pissed because the ghetto wire flung on the roof will have to stay (well, at night when I'm listening, anyway).

Nope, I did the same thing you did and made a 2' loop, with a few inches left to spare to solder to the coax. I just bought a 25' spool because that was the smallest spool they sold of the wire. If you're not getting ANY difference when tuning, it's got to be your capacitor. Just so you know, I experience the same drop in volume you do, until I actually tune in the channel with the capacitor and then it's booming.

That's weird. I'm on my second capacitor and it hasn't changed a bit. I dunno. Maybe a bigger radio = bigger capacitor. Maybe I'll head to walmart.

I may have actually gotten my dumb-rear end loop antenna working. I put in a third capacitor, and it does seem to be tuning when I get up toward 10000 KHz. I\'ve had a few stations get moderately stronger while tuning, so I guess I\'ve finally got it right. Now I just need to fiddle with the whatsits on the back of the capacitor (I forget what they\'re called) to tune it down a bit. I\'ll probably wind up seeing if disconnecting one of the tabs from the short makes any difference, too. I was expecting a little more, but I honestly haven\'t thoroughly tested it across the whole spectrum, so we\'ll see.

At least there wasn\'t any violence involved.

I don't hear HAMs very often either, but I'm generally listening pretty late at night. When I listen around 5pm CST, I always pick up at least a couple if I'm not scanning in a hurry.

I used to autoscan with my E5, but now I pretty much manually scan all the time. I catch a lot of faint stuff that the radio might skip. The autoscan is functional, but if you want to really use it you have to watch the frequency and stop it when it skips over, then go back to where it skipped, move up a few KHz, and restart again. I agree, it's definitely a bit of a hassle. But it sort of forced me to listen a little more closely, too, which (for me) was good.
