Re: LF: EbLaunch - an easy application for managing Window's EbNaut-rx

[Roger Rehr W3SZ <w3sz@comcast.net>]

Hi Paul,

I also get the PRQ R decode if I have message length set to 6.  But if I
set message length to 5 as suggested by Domenico, I do get the expected
DF6NM decoder output.  See attached.

I also do not know why the strange time offset...I get the same start
offset of -195540.05 that you got and have to manually enter the 160.95
into the decoder.  But when I do that, it works :)

You should also get a nice FFT when you click Launch Show_raw_sy.  I
attached an example.  If you don't see that then your settings are wrong.

And then setting frequency to 137522.000313 and message length to 6 I
get IW4DXW decode as well, also attached, as Result2 and FFT2.

73,

Roger W3SZ
