An FM APRS signal has been received in England causing interference to the MGM frequency and weak-signal Meteor Scatter operation which is just below 144.390 MHz.
A MS DXpedition was disrupted by such activity earlier in the month and interference has been occurring at various times since. The APRS frequency in Europe and Africa is 144.800 MHz. Today (July 30) a signal on 144.390 MHz has been decoded as
15:17:27$ fm W3ADO-1 to BEACON-0 via SGATE-0 UI PID=F0 T#004,161,161,042,210,215,11111111,0011,1 Now I know nothing about Sat Gates and how they operate but I presume that is what the SGATE-0 is referring to ?
I have seen a reference to W3ADO-1 at http://www.db0anf.de/app/aprs/stations/basic-W3ADO-1 Does anyone know if 144.390 APRS is installed on any current orbiting satellite or is anyone aware of a terrestrial network that may be relaying APRS traffic on 144.390 in the British Isles or Europe ?

W3ADO-1 on 144.390 is most likely PCSAT NO-44, it has a safemode downlink on 144.390
All satgates responding to sgate that are used gate from 145.825 to 144.800 in europe but there are not that many, most satgates do not look at sgate alias and gate to internet everything from 145.825.
