I'm about 30k from LFBM and there is a lot of military activity some days, transport, helicopters and dogfights. Generally nothing shows up on FR24, but it seems the odd one does for some reason, but it's very rare.

Wireless Telegraphy Act 2006
 

Vin Rouge "Apart from that being technically illegal in the UK, in accordance with the wireless telegraphy act 2006." Which bit of the above act states that it is illegal to receive wireless signals, other than those used for the reception of television signals, for which a license is required? It is my understanding that in the UK it is NOT illegal to receive wireless signals outside the TV spectrum, BUT, that in certain cases, it is illegal to act on the information received, hence the massive payouts by certain newspapers, revealing information from hacked phone calls. So if I see an aircraft on my computer screen, with a callsign of, say, Kitty 1, and it is squawking 7700 and I then call my local TV station to tell them that an aircraft carrying HM Queen Elizabeth II is in distress, then I am breaking the law. (Oh and by the way, I don't use a wire coat hanger as an antenna, rather an eight element co-linear co-axial (CoCo) antenna which gives me reception of ADS-B out to about about 220nm.)

Is it not still illegal to monitor the emergency services. It once was, but times change.

Emergency Services broadcast
 

Beardy,
I Believe that the emergency services use a system to broadcast and receive transmissions called trunking. Your average cheap scanner, in particular air band radios for the aviation enthusiast certainly can't do this. No, I don't know how it works and I've never understood the instructions on my iComm receiver showing how it works. I know that the PSNI not only use this but also use encrypted radio so I suspect that various other forces also encrypt their radios. As I said previously, if it IS legal to listen in to such transmissions, it is most certainly illegal to disseminate what you have heard. Perhaps those with MUCH more knowledge of the subject than I could help us out on this. Interestingly, am I breaking the law by feeding my ADS-B info to an American company based outside the UK legal and justice system. Similarly, if I feed the live position height and speed of Air Force One, is the US SS going to try and have me extradited for having revealed D J Trumps position to the world?

Oddly enough, that F35LTNG with the AF351F hex code displays on FR24 for several different F-35's including this Israeli aircraft:

It does, some.

Few weeks ago, big racket over Berkshire around 3am, FR24 showed mil transport into Brize ex NBO, presume with pax for Hereford as this was a couple of days after the hotel terror siege.

Great title from a Garmin page:

If you want to view the map of flights without blocking you can click on this link (and play around with the settings to filter the planes if you like):

Go to Global Radar View, Global Radar.

Lists of currently visible military aircraft are here:

The reason some Mil show on Flightradar is when the HEX code is wrong as they block us from seeing certain HEX e.g from RAF aircraft sow hen its wrong, they show e.g the Lighting the other day.

If the military aircraft does not turn on Mode S (or probably more usually leaves it in standby) then it will not show. There may be areas of airspace that require Mode S to be turned on - then you will see it. If the military aircraft sets emergency on its transponder, then the emergency is automatically sent on all modes - hence the emergency indication seen on Mode S from the F-35. At the end of the day, the presence on the screen for Mode S/squitter depends upon what the aircrew set on their transponder and their emission control instructions.

They actually come from different feed networks. FR24 has much better worldwide coverage but as you say is, for the most part, filtered.

Depends where they are. I will also add that a Mode S interrogation will trigger a mode 3 response and so Mode S in standby is no big deal.

Interestingly, ADSB with military filter applied currently shows a German registered hot air balloon travelling south at some speed and 20000' across the Netherlands...:p

Experiment with menu=> layout and see what suits you best. The screen can have three parts: a map, a list of all the a/c on the map, and details of the highlighted a/c.
