We could make our own Goon numbers station. Our call up would just be a high pitched winded voice saying 'Get Out! Get Out!' and signal that the transmission was over would be 'Go back to GBS'

Welcome to the club! It is a remarkably addictive hobby, and is very much a gateway drug to ham radio (I just recently got my ham license, callsign KF7JKA, general class). Radio technology just has a mystique about it that computers and the internet simply don't have. There's something extremely visceral about the hisses, warbles and spooky sounds you have to trudge through to get to your signal.

So were any of those antennas from radioshack/ebay worth purchasing? I'm so bad at building stuff I just know I'll get too frustrated with building a magnetic loop.

I bought RadioShack's AM loop a few years ago when it was on sale, works pretty darn well. Downside is that it only works for the AM broadcast band, not shortwave. For shortwave I bought a Degen 31 which is a amplified shortwave loop antenna and it works pretty well too.

http://www.radioshack.com/product/index.jsp?productId=2405978&filterName=Category <- I would not pay anywhere close to $40 for this, I only paid $15 when it was on sale. Maybe eBay offers them cheaper?

http://cgi.ebay.com/DEGEN-DE31MS-MW...=item19b455d39a <- Pretty reasonable price, there use to be many more sellers on eBay but I guess these antennas are almost gone.

I have the Degen as well and its much better than the built in whip when used indoors. So if you cant build your own and don't/can't run a long-rear end random wire antenna its a nice way to go. There is one downside you constantly have to fiddle with the tuning knob when you are just surfing around for stuff on the air. It's much easier to use if you are going for a particular station.

Really the Degen is cheaper than building the Mag loop, I really don't know what works better. I never got decent performance out of my homemade mag loop, but I did a lovely job.

With the Degen antenna it was the difference between hearing a station and hearing nothing with just the whip. It's not magic but its not bad to play around with.

Wow, I'm not sure if this was common knowledge but you can tune the Degen 1103 below 100 KHz through some simple button pushing. The same button pushing also allows broadcast AM reception through the ariel whip rather then the internal ferrite antenna. Basically hit 1 - 7 - 1 - 1 'band+' then hold 'Band -' for 2 seconds and from there you can either use the tuning knob or just let it scan. I don't think there's much below 100 KHz beyond time signals (WWVB 60 KHz sets atomic clocks) and digital submarine communcations. There's also a way to button push your way above 30 MHz to 35 MHz but since most transmissions there are FM that isn't too useful.

Well, looks like I've been bitten by the fantastic Eton quality control! My shiny new g3 is an early unit (sn 000024) and has the howling noise when I try to use sync so it looks like it's back off to base for this little one and see if they can send me a more recent problem-free unit.
Apart from the non-syncing, I'm having a good time with it, got my long-wire thrown up and listening to all sorts of crazy crap - even got the Mrs freaked out when I told her about number stations, if she gets any more interested it may be a good excuse for another radio!

Is it alright if I use copper to build the coupling loop on a magnetic loop antenna?
The site linked earlier used steel but never really said if it needed to be that way or not and the "magnetic" part of that name has me unsure.

It should be fine. In fact, I've seen some sites suggest copper. It's not magnetizing the loop, it's using the loop to create a magnetic field. Different.

I've been listening to this on 9202khz USB for nearly the last hour now, I found it whilst looking for an E10 broadcast, which is also supposed to pop up on 9202, anyone have any ideas what it is? The signal isn't great, but you can make it out. The pitch changes are just me messing about with fine tune, otherwise it has been the same pitch throughout.


EDIT : m51 is on 5184usb, as of ~22:00utc
EDIT EDIT : pah, after some more reading, M51 isn't actually a numbers station at all, its a french morse training program. or is that exactly what they want us to think? :tinfoil:

edit: A bit of research indicates it is a Federal Telephone & Telegraph Type 61 Receiver, but I haven't found anything on whether it receives short wave signals.

The only useful information I've been able to find on Google is this:

quote:

Federal Telephone & Telegraph Co.

Type 61

Introduced in the fall of 1923, the Type 61 was Federal's high-end receiver, selling for an incredible $223. The circuit used six tubes - three RF amplifiers with grid-bias controlled amplification running into the detector stage and two transformer coupled audio amplifiers. One could select either one RF stage or three RF stages, a loop antenna input or external antenna input. One could also select various audio amplification circuits and the second audio interstage transformer has a selectable ratio secondary. In all, sixteen different configurations could be set-up, making the Federal 61 one of the most versatile battery receivers of its day. Though the manual is vague about the regenerative capabilities of the Type 61 ("regeneration" is never mentioned), performance can be excellent if the "COUPLING" is kept near minimum and the "RF AMPLIFICATION CONTROL" set near the oscillation point.

($223 is $2779.50 in today's dollars)

I don't know whether this is a shortwave radio or not; I put the reference card photo into Photoshop to lighten it up and I don't know exactly what all of the dials do. It might be a shortwave radio, it might not be, :confused:

It is worth a decent amount of money; I came across several auction listings for in the neighborhood of $1500.

The only other useful information that I could dig up is that it was a hot performer in its day (and still would be), but it's very touchy to adjust.

Wow, I had no idea it was worth that much. Later on when I have some time I'll try and put the reference card through my scanner instead of taking lovely cell phone pictures.

Is there anything specific I could look for on the dials that would identify it as short wave capable?

edit: I checked with my grandmother (the radio belonged to my grandfather before he passed) and it IS a shortwave radio. However, I'm imagining that the battery required for operation would most likely be more expensive than going out and buying a new shortwave receiver, so I don't think I'll be using this mammoth machine. I may try and talk my dad into Craigslisting or eBaying it. I did however find out from my dad ("Why are you so interested in shortwave radio?") that there's another antique radio in the house that only needs an antenna and a new set of tubes to work properly.

All I know about it is that it's a Philco radio. I can't find a model number anywhere on it. I'm thinking of getting in contact with the proprietor of one of those antique radio sites I stumbled across and sending him a few pictures, but here it is nonetheless.

Countries with the biggest shortwave audience loss include Bangladesh, India and Nigeria. All this while BBC's audience is growing online and growing in areas where there are local FM relays.

Shortwave is defined as 3MHz to 30MHz, or 10-100 meters. Looks like your "secondary wavelength" dial has numbers that fall in that range, so it should be able to receive shortwave freqs.

However, if you're just wanting to use it for listening and don't have any interest in collecting antique radios, I'd sell that thing and buy a G6 or something for <$100 that will be much easier to use.

My dad's kind of attached to it. It was his grandfather's, so I doubt selling it is an option, although as previously mentioned, something in the ballpark of $1500 would buy me a nice little shortwave radio, and give my father a nice deposit into his checking account.

Ah well, looks like I'll just have to tighten my budget for a few weeks if I want to get in on this action.
