Good day
btw it`s spring time ;-) Colomba was launched last Saturday. Some
minor things have to be done and I hope to get the ham radio station
running on short wave during the next days.
Whatever .... one thing is not running. Unexpected and I do not have a
real idea what happend, cause in autumn everything was fine. The Navtext
reader, Nasa Clipper 147 does not work correctly. Main problem as I
think is, that mark is at 147.3 kHz and shift is app -60Hz as shown in
spectrum display. It`s receiving messages, but it`s only a lot on nonsence.
Unfortunately I do not have any circurit plan of this Navtext so it`s
hard to find the failure. All condensators seems to be ok, no one blown
up or seems to be destroyed. If I try to turn one of the 4 inductivities
nearly nothing happens. Perhaps someone has an idea or a circurit plan.
best regards
Peter
