899	05 Feb 19:40 VIPER (Ionosonde) and Digisonde (and synchronization)	kkuyeng		"VIPER configuration
- ionograms every 5 minutes (3, 8, 13, 18, ...), so it won't interfere with digisonde pulses.
- IPP = 3000km (ISR + Imaging is synchronized with PPS)

Digisonde
-ionogram every 5 min (0,5,10,15,...)
- its tx pulse is seen at the top of the 1000km of the ISR + Imaging experiment.

*ISR+Imaging
- syncrhonized with PPS, then must restart Digisonde clock (10MHz) to put its tx pulse as close as the PPS (shown on osciloscope). Right now it is ok, but in case of a blackout this needs to be done."	Other Instruments	new	normal	2016_02_1 ISCOD Gravity Waves	ISR+Imaging
