Hi Johan,

I am just following on your question to see if it is resolved.

I noticed a connect from you to SM0RWO a few days ago. So have you resolved the 
problem?

Regards,

John

Hi John,



With both versions 3.10 and 3.12.4 it's impossible to work with a node. After 
the first frames I have a chance at a connect but that ends during moving of 
the RX freq. And it moves more then 100 Hz although the search settings are set 
to 10 Hz. It is pc depended, another laptop works fine. All other modes are 
working fine. Only psk has the problem.

Waiting for 3.13

Thanks

Regards

Paul; pa0son

Hi Paul,

I will try to find out if there is a target release date for Fldigi 3.13.

I used the alpha version of Fldigi again today with Psk125 and 250 for Pskmail 
and the settings I gave you before produced a very stable decoding. With older 
versions (like 3.10) I would have had a few frames damaged simply because of 
this jitter.

Regards,

John

Hi John,

Tnx for the quick reply. Unfortunately I tried these settings but without 
result. In all other modes, like RTTY, MT-63, Olivia RX-fldigi is I don't have 
that jittering.

I really hope that 3.13 version will come soon, I have some enthusiastic HAMs 
to start with pskmail tests, but that delays due to this jitter problem.

Paul,

I assume you mean when using the PSK modes. If so, in the modem/psk 
configuration tab, adjust the signal acquisition S/N up (I found 13dB was ok 
for me) and the search range down ( had to put it at 10Hz). The upcoming 
version of Fldigi (3.13, when it comes out) seems to have resolved that jitter 
issue. In the mean time this is the workaround.

Regards, John

Some weeks ago I had a laptop 1.1 Ghz and fldigi 3.12.3 and jpskmail -win 
resulted in a jittering fldigi rx. Using XP. I went to fldigi 3.10 and the 
problem was solved.

Now I try to set up a laptop XP 1,4 GHz for a fellow HAM and fldigi 3.12.4 as 
well as 3.10 are jittering.

Any tip?
