"...........In my decoding from the recording of program to be broadcast 
13-14 July, I was able to see the accent marks in the first Spanish item,
greetings to the Encuentro Nacional Diexista 2013, a meeting of 
shortwave listeners in Mexico City.
But in the second plain-text Spanish item, a VOA news story about 
Pluto's moons, the accents were no longer visible.
If this happens to you, during the Pluto story, try closing Fldigi and 
opening it again............."


Yes, it happens..........


"............Another change for the 13-14 July program is that the 
Optimod audio processor will be used at the North Carolina transmitter 
site for
the broadcasts Sunday 0230-0300 UTC on 5745 kHz and at 1300-1330 UTC on  
6095 kHz.
So far, we have not been using the audio processor that is typically 
present for VOA shortwave voice broadcasts because of our concern
that the processor might affect the spectral purity of the digital tones.
This weekend we will find out if the audio processor has any adverse 
effect on the ability to decode MFSK and EasyPal.
(Radio Australia used the Optimod during its recent digital text tests, 
with no problems at the transmitter end and no apparent reduction in 
the  ability to decode.)................."



I had received the VoA radiogram on 13.07.2013 at 16.00z on 17860 kHz 
(without Optimod).
This time there were no problems in the decoding of the QAM4 signal.
I doubt strongly that OPTIMODE is useful for digital modes, rather the 
opposite .......
Here are my decoding results:
