Signal recording possibility?

[cutty]

Hello,

is there some option to record raw signal samples from system Blue?  We want to use the blitzortung station as trigger unit for other devices on board the storm chasig cars.

For now we have the system Blue station instilled on board of the car as mobile device. It seems the station could be relatively effectively used for waveform visualization in "monitor" mode. But it could not be used for scientific analysis until we have the raw signal wave forms of each lightning.

We are especially interested in the "nearby lightning" e.g. up to 20km from the car. I suspect the range could be partially selected by altering the gain.

As partial solution of the signal recording we tried to sniff  the UDP packets sent to the servers. But unfortunately, the signals seems to be filtered and only a portion of detected signals are really send to the servers.

What is your User ID and Station Number?
Need to confirm and upgrade your status.

Each system BLUE has test outputs, optional, install SMA jacks.  One of those outputs is RAW analog signal prior to  ADC.  You could shape trigger with that.  BUT it would only be a 'trigger'.  I'd suggest the E channel, since it's basically 'omni', while the H channels are lobed.  The 'signal characteristics' are actually done on the server, not the controller.  A single BT station is simply a wideband analog to digital receiver. It doesn't know where it is, for example. It will send that periodically, but doesn't remember it. All it uses is the synced 1PPS. The server  knows, however.  So you keep moving around, server may decide you have a GPS problem, for example.
Not designed for your application, as such.

Second... distance is NOT related to an individual unit. This is not a 'stand alone' system. It depends on the network to calculate. Local  doesn't know where the stroke occurred, just that it did. All you'd have 'locally' is YOUR signal data, not the computed analysis. 

Correct on the compression. That is decided  by the controller, relative to some feedback on occasion from the server. Not all data needed for BT purposes, currently, so it's not sent to save BW,etc.  And when it reaches the servers more adjustments are made. Your are 'relative' to every other station, and a GPS sync.   Secondly, on the server, a 'footprint' for your data characteristics is maintained,  and incoming signals compared... so if you keep moving, that 'footprint' is apt to change, and it's possible for the server to consider your 'new signals' not-valid, since  your spatial movements keeps changing the time  relativity between 'expected' impulse signals.
