 Smile Hi everyone!  Smile

I've just bought the Maycom AR-108 and it'll be here tomorrow.
Now, I'm a little worried that I have picked the wrong scanner . . .  Sad

I've just read that if someone should happen to buy a new scanner, make sure it has 8.33kHz step size as some UK frequencies now need this to listen into ATC communications.

(As we are not allowed to post copyrighted material, here is the link):

Scroll right to the bottom.

So, how long will it be before I have to buy another scanner?
Or, even how long until all of the UK Frequencies change to 8.33kHz step?

Thanks for all your replies!

Well, I've got the AR-108 and it is FANTASTIC!
Brilliant!
I'm listening to East Midlands Approach right now and the voices are soooo clear!
I usually get aircraft flying over my house (as we are under the flightpath through the midlands) and I wondered if I would be able to pick the transmissions up from them, but what frequency do I have to put in?

Thanks for your help.

...then you follow departing aircraft from freq to freq until they're talking to the en-route controller. Then monitor that freq for aircraft coming toward you and listen for them to read back a frequency change. Eventually you'll hear someone read back the freq you need.

You don't have to worry the AR-108 is quite a good scanner.

Well, I've figured out how to listen in and it is brill!
But, (now for my next question), can I listen to the aircraft flying over my house? Thanks for 'Timz' reply, but I wanted to know an exact frequency for the East Midlands area. I have found these frequencies, but which one will be used in the East Midlands area?

Here are the ones I have found:

{UP TO FLIGHT LEVEL 195}

TMA South East: 134.425

TRENT Sector: 133.4

TMA North East: 126.65

BOLIN Sector: 125.1

TMA West: 128.05

Spare: 125.95

Which one will be in use for the East Midlands area.

{FLIGHT LEVEL 195 TO FLIGHT LEVEL 275: 118.775}

{FLIGHT LEVEL 275 TO FLIGHT LEVEL 325: 129.1}

{FLIGHT LEVEL 325+ : 131.05}

Thanks for your help.

...is get out the binoculars. Hopefully a few of those flights are visually identifiable-- or is your sky never clear? But if you hear a Lufthansa flight at FL310, and you look up there and see a LH 747 at contrail height, then watch him until he's out of sight and maybe he'll do something to confirm the ID. And go to amadeus.net or some such place and confirm that that flight number is a 747. If the same thing happens day after day with different flights, you must have the right freq.

So shall I just try all of the frequencies until I hear something?

You mean you haven't heard anything yet on any of them? If so they must be wrong. Unless you're surrounded by hills you can hear a high-altitude aircraft at least a hundred miles away. If you do hear an aircraft but he doesn't ever show up overhead, listen for his readback of a frequency change-- e.g. "one three one decimal zero five, good day." That gives you more freqs to try.

I've heard things from the BOLIN sector and the FL195 to FL275 one.
But how do I know if thats the one above me? They one i'm listening to could be over Manchester or Birmingham for example!

If your sky is always overcast then dunno. But if you can see them, and if you can maybe identify the airline with binoculars, then eventually something ought to come along that's distinctive enough that you know it's the one you're listening to.

But if you can't see them at all...
