Re: [wsjt-devel] No decode on strong JT9 signal

2015-02-18 Thread Joe Taylor
Hi Mike,

Thanks for posting those troublesome wav files.  As it happens, I have 
been busy looking at a number of similar examples of problematic files.

More or less from the beginning, the JT9 decoder has failed without 
obvious good reason something like 1% of the time... and I'd like to 
understand why.

Over the past several days I've been playing with an independent, 
stand-alone JT9 decoder.  It goes through many of the same steps as the 
decoder in WSJT-X, but it organizes them in a rather different way. 
Here are the decoded results of your three files:

1336  -4  0.1 3215 @ CQ AE5ZZ EM34
1338  -6  0.1 3214 @ W9MDB AE5ZZ -18
1340  -6  0.1 3215 @ W9MDB AE5ZZ -15

So YES, your example files are all decodable.  Now I need to see whether 
I can move capabilities of the test program back into WSJT-X without 
destroying its snappy performance.

 1336 is the initial JT9 decode that I replied to for AE5ZZ at -4dB

 1338 is the response.but it doesn't decode.

 1340 one is the next response.but it doesn't decode either.

 I tried these files on another computer with the same result

 So either he lost time sync or the decode failed for some other reason.  I
 was able to complete a QSO with him later.

Re: [wsjt-devel] No decode on strong JT9 signal

2015-02-18 Thread John Williams
Hello,

Running Xubuntu 14.04 64bit using wsjtx_1.4.0-rc2_amd64.deb. Trying to 
use CAT net rigctl to QtRadio (localhost:19090). Get a consistent error 
of Hamlib Error: communication timed out while getting split TX vfo. 
Buttons for split operation seem to have no effect. Get same error for 
none, rig and fake it. Also tried none on Mode and same failure.

Are there later fixes for this in the current svn source? Should I build 
the latest source level to correct?
Does the RC version offer any debug logging of ptt commands? If so, where?

Also, I have a hacked version of WSPR 4.0 that supports net rigctl to 
QtRadio. Is there any interest in using my diffs to add support? If so, 
will post...
