G7IZU RRD WEBLOG

System status 03/11

2009-11-03T12:17:00.001Z

The G7IZU RRD system is now suffering badly due to a shortage of available transmitters to monitor. On 31st October at 23h UT, the analogue TV transmitter in Prague on Ch R1 was switched off as part of digital switch-over. TVE-1 Navacerrada near Madrid in Spain on Ch E2 is drifting badly and has become unusable. It’s also overdue for close-down. My last remaining useable channel is Ch E3

Since then the frequency has been quiet, apart from a few pings from a transmitter 20Hz away that is in neighbouring Hungary . It also appears that the channels’ second frequency of 59.257

I’ve spotted it about 350 Hz high slowly drifting higher in frequency. It’s been drifting away on and off for years, but it seems to be getting worse! This bad behaviour has upset meteor for myself and
