12 September 2017
Many of the current listening squawks will change this Thursday, 14 September, and five more have been added, making a total of 21 around the UK.
A listening squawk enables an air traffic controller to alert a pilot if their aircraft looks likely to infringe controlled airspace. The pilot needs to turn on the aircraft’s transponder and select the listening squawk, using ALT (Mode C) if available. Tune in to the allotted frequency without transmitting, and listen out for your callsign or position.
Air traffic control will know that you are listening out and can call you on the frequency if you are getting too close to controlled airspace. Once you leave the area, or change radio frequency, change the transponder code back to 7000.

Useful info thanks. Looks like a typo in the East Midlands frequency though.
This is good news.
In the article you have changed the East Mids frequency to 137.175, whereas the LARS poster remains at the current frequency of 134.175. is this a typo?
Yes, it was a typo, not ours originally but thanks for pointing it out.
I find the previous format clearer with the coloured blocks down each side.
