The frequency equates to an IF of 1065 MHz, +/- 15MHz which means it could be JTIDS ground station

The Joint Tactical Information Distribution System (JTIDS) is an L-band TDMA
network radio system used by NATO to support data communications needs,
principally in the air and missile defence community. It provides high-jamresistance,
high-speed, crypto-secure connectivity.

NATO operates JTIDS over 52 frequencies in the frequency band 960 to 1215
MHz. The operation of this system is agreed on a bilateral basis between the
military and civil aviation authorities within each country and is normally subjected
to some form of frequency clearance agreement

While the system is capable of transmitting on a single frequency at 969 MHz, the
normal mode of operation is where individual pulses are transmitted using a
pseudorandom hopping sequence across 51 carrier frequencies (3 MHz spacing)
in the 969 to 1008 MHz, 1053 to 1065 MHz and 1113 to 1206 MHz bands
inclusive.

Note that emission within ± 7 MHz of 1030 MHz and 1090 MHz are at least 60 dB
below peak with reference to the maximum JTIDS/MIDS signal level measured in
a 300 kHz bandwidth

Pity there are no adjustable notch filters you can buy for satellite frequencies ..
I might have a chance If I could pin down the exact frequency ..and notch it out ..

...'course ..you'd have to notch in the IF range..

Thanks for the info CH ...
Looks like I'm stuffed then ..
No chance I could phone 'em up and tell 'em to turn it off then ..
doh!!
