[Scan-DC] Drones and airport stoppages

[John Wilson]

Here are the authorized drone control frequencies in the US:

Digital Duplex Control:

Ch. 1 5,885 mhz.
Ch. 2 5,905 mhz.
Ch. 3 5,924 mhz.
Ch. 4 5,945 mhz.

Great!  Now all that has to happen to prevent drone interference is to 
transmit a wide band 5-6 Ghz. signal. at the airport. Be careful. There 
are other licensed and government users in the 5 ghz. range (TV station 
WX radar, etc.) and 6 ghz. contains a significant number of PTP links 
like in my county with 6 different area towers for their various uhf 
radio system comms. In any large metro area odds are somebody uses 5-6 
ghz. and will get RFIed.  If ISIS can configure remotely dropping a 
grenade from a drone at 300 ft., you have to assume ISIS is not using 
these "standard" frequencies but some different microwave or different 
frequencies, i.e., vhf frequencies for more transmit power and higher 
altitude and control.

There are many answers to your question of "why".  In every country, 
none excluded,  there are idiots of various stripes, troublemakers, 
thrill seekers; someone who has to "prove" something; USA haters; media 
publicity seekers, personal vendettas or grievances, Islamic and "home 
grown" terrorists, those desiring historical immortality, etc.  The list 
goes on and on.

When one of these jerks gets caught, no excuse of ignorance or plea 
bargaining allowed; have a mandatory sentence of 10 years in federal 
prison where there is no parole and a mandatory $100,000 fine. When that 
happens the word will get out to the other fools who persist.
