[time-nuts] Softpal VLF software
I've recently been in touch with Kit, the developer of Softpal (lives in Dunedin, New Zealand). He took some effort to locate. The software is commercial, and runs on a Labchart (commercial instrumentation) package which you also have to buy, and that's the expensive bit. The software does indeed do as he claims, and we have had some useful discussions. Like you guys, I'd love to try it out! I'm trying to negotiate a shared development for use with a conventional Windows platform. Kit is interested in doing this, but don't hold your breath!

Re: [time-nuts] Softpal VLF software
That is interesting indeed. I am interested in wwvb propagation also. But my interest has no commercial value at all. I do plan to re-look at some of the alternate suggestions. Though at the moment I am using the cheap DATQ software and reader $29 to log 3 channels of data. (It has 4 cnls) I feed the phase comp out from 2 X HP 117 and 1 X Tracor 599 VLF rcvrs to the DACQ encoder and watch the strip chart 1 per hour on a laptop. Logging to the internal disk. Still getting used to how you drive it all and the info is exportable to a number of formats like excel. About the only conclusion I really have now is. Boy does the ionosphere jump around. But then thats been known since the 1930s.

Re: [time-nuts] Softpal VLF software?
Google found this http://www.lfsoftpal.com/ it was everything but the software. I had the idea too that I could monitor some stable LF and HF transmitters and use that to infer what the ionosphere is doing. Plan to use WWV and WWVB and compare the time I get from them to true UTC. I assume any difference and jitter is because of patch length.
