Evening Giuseppe. Made the changes and ran for over 300 pages of the waterfall, but alas nothing was seen on the recording. Hopefully due to there being no activity. Screenshot attached. One thing I noticed was that each of the dumped waterfall images had the same time stamp on them, is this normal? They did each have a separate individual image number. Getting there slowly, thanks for your efforts Regards Alec On Mon, 1 Mar 2021 at 14:17, gmbertani gmbertani@users.sourceforge.net wrote: Hi alec,...

Thanks Giuseppe, I mistook your info, and set the resolution Hz at the high figure and not the FTT points. Now reset and the window looks better. It must seem worse than teaching a child, dealing with me! I have the set up now running and hope to see a blip or two.

Hi Giuseppe Apologies for having to come back again. Followed your instructions, but probably got it wrong. Waterfall is running and saving a dump every 40 sec. But the screen looks odd, not sure why, obviously I have something wrong? See attached screenshot.

Many thanks Giuseppe for all your help and suggestions. I will let you know how it goes.

Many thanks Giuseppe, apologies for the question, with such a simple answer. Followed your suggestion to stretch the box and the options appeared. Now set to Auto to only produce plots when something detected. Also when I clicked on gnuplot this time program did not crash. Hope to set up tomorrow and hope for a meteor in the near future. Very many thanks yet again. Best wishes Alec On Sun, 28 Feb 2021, 22:07 gmbertani, gmbertani@users.sourceforge.net wrote: Hi Alec, 1. The default window size is...

Hi GiuseppeI now have Echoes running with the dongle connected to an aerial, it seems to be working as different frequencies give different traces. Just a couple of issues. Under Output, no options are given for setting the Acquisition Mode, see attached screen shot. Am I missing something? Secondly, if I want reports presumably I need to download GNUPLOT? Currently if I enable this in the Main Window, the programme crashes. Thanks for your help, kind regards Alec On Tue, 23 Feb 2021 at 23:00, gmbertani...

Morning Giuseppi Excellent, Echoes can now see the dongle. Very many thanks for all your efforts and patience in dealing with a newbie. The next issue I have of course is to get some sort of understanding of how to get Echoes working! I have looked through the user manual and understand bits and pieces, but it is a steep learning curve. Is there a crib sheet to simply set Echoes up to get signals from the Graves transmitter? Thanks ever so much for your efforts. Take care Alec On Sat, 27 Feb 2021...

Hi Giuseppe, sorry about the delay getting back to you. had a look and the dongle gives 2 items under USB (simply called Bulk-In, Interface) see attached. I have copied the Driver properties info for each. I think they are identical. Hope this helps Regards Alec On Wed, 24 Feb 2021 at 22:06, gmbertani gmbertani@users.sourceforge.net wrote: Could I ask for another information? I need the USB identifier number of your NESDR.
