I've been thinking about getting this kit to build, but I'm hesitent on spending $50 for a kit, and mess up and it not work

http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=AR1C

That would be a lot of fun.. and good learning

It would be a great, secondary monitor.. but you'd find it tiresome, trying to switch channels while following a jet from clearance delivery, to ground, to tower, to departure.. and of course not being able to scan several channels between "action".

Of course.. at a busy airport, there's plenty to listen to, one channel at a time Cool

True, and if it doesn't work, i'm out $50, and then I would end up buying a scanner. Or I could get a scanner and be able to pick up a wider range of frequencies

I saw this on radio shack's website. I wonder if it's any good?

PRO-164 1000-Channel Handheld Scanner
http://www.radioshack.com/product/index.jsp?productId=2970547

This site has more information
http://www.scannermaster.com/RadioShack_PRO_164_Police_Scanner_p/22-501222.htm

That would be an excellent choice. It's a newer version of my scanner. You'd be hard-pressed to outgrow that thing.. I'm still learning to use mine, and THAT one has more features.. The ablility to auto-tune to nearby broadcasts is intersting. Drive around apartment complexes and listen in on cordless (not cell) phone conversations.. LOL Lips Sealed

The second one appears to be the US regulations.

As an Electronics Engineer, I spent many years in my Garden Shed designing and building Valve Radios, Valve Audio Amplifiers, and Valve Radio Transmitters...anything with glass Valves, (still got loads of them!).

..but I could never be able to "operate" the Transmitters without a Broadcast Transmitter Licence....but it was a lot of fun building them...

It's pretty strictly regulated here too.. You can't just build a transmitter and start broadcasting Cheesy

.. well.. you CAN, on the Citizen Bands and the new UHF "personal communication device" frequencies, that all these new radios use.

http://www.bestbuy.com/site/olspage.jsp?skuId=9170078&st=radio&type=product&id=1...

As far as listening goes.. well.. common sense applies. No matter HOW many laws they pass, it's impossible to stop someone from recieving a radio broadcast Wink

While were on the radio subject, let's have a 'way-back' moment!

Who here as ever strung copper filament across the backyard and hooked up a crystal radio that they built from a kit?

Note to da youngsters.....no need for batteries!!! Shocked

The only thing I ever received, was a pair of hot ears, through wearing headphone for many hours in the vain hope on hearing "something"...which rarely happened... Grin

An interesting fact: A Radio signal reception could often be obtained just by connecting the Headphones directly to the long Aerial. The coil within the headphones often tuned itself to an incoming signal; (AM Amplitude Modulated)... Wink

I made my own from an article in the Eagle comic (or it could have been the Boy's Own Paper). Mine was one of the later types with a germanium diode & variable capacitor for tuning. The aerial stretched from my bedroom window right to the bottom of the garden, strung along the top of my Mum's washing line poles. It worked rather well but I suspect the proximity of the aerial to the relay radio cable might have had something to do with it. Roll Eyes

For communication over relatively short distances, I finally abandoned the "Crystal Radio" idea, and replaced it with an improved, later version, involving two Baked Bean tins, and a long piece of string...

Worked a treat between my Bedroom window, and the Bedroom window of the delectably young Schoolgirl living next door... Kiss

It doesn't happen any more... Cry

I thought that the frequency for those cordless phones were in the GHz range?

Mine is a Pro-something .. I'll have to dig it up. It's about 8 years old.. but the specs sound similar..

YEARS ago, cordless phones used 24 and 49 Mghz (same as baby monitors).. then they went up to 900Mghz.. now, I think you're right, they're probably in the 2+Ghz, and quite possibly encrypted..
