V07 on July 09, 2017

13563 kHz USB, 09-07-2017 0700, 512 512 512 000
12163 kHz USB, 09-07-2017 0720, 512 512 512 000
12163 kHz USB, 09-07-2017 0724, 512 512 512 000

Note the unusual repeat on 12163 kHz at 0724z.  This was also at a significantly lower power level, so not sure what was going on there.  The 0720z TX was S9 or a little over, the 0724 was S7 and lower.

The voice has changed as of last week from what it has used for the last 5+ years.  It sounds fuller and the tempo has been sped up a bit.

Recording here, left channel is the null message sent on 12163 kHz USB, July 09, 2017, right channel is the null message sent on 12182 kHz USB, July 12, 2015.

And a spectrogram here, pointing out some changes to the voice.

There has also been a frequency change starting this month, deviating from the frequencies used in July since at least 2011.  It will be interesting to see if all of the freqs, for all months, have also changed.  Last month was on the old freq sets.

Old freq set here:

But so far this July they have used 13563 khz and 12163 kHz, instead of the XXX82 kHz freqs they used previously.

I wonder why they change the voice for V07?
