I made the changes to a conversion program
of my own to invent a PSN4 file for my data
and wish to announce that since I have
placed the fractional value of the start time
times a billion into the NANO SECOND
area the times I now get from winquake appear
to be proper. I have tested this using
pulse marks made by myself then gone back
into the program and checked the times.
The proper way would be to use WWV minute marks
I have not yet done this however I expect for
amateur purposes that would be correct also.
I now feel I can resume sending reports
to whoever and expect the times to be correct
or as correct as can be for my station.
GVA teleseismic events appear very close agreement
in form to the fellow in Washington State so I am
guessing that phase (up is up) is proper also.
I only do an SPZ channel so can not compare
with those using N or E sensors.
Roger Sparks Device seems to have a lower freq
response so our comparisons will rarely
be exact yet they seem very close in appearance.
