Special thanks Pigmon !!

SEP SKD by Pigmon:
The USB frequencies were changed on September 5.
The updated USB frequencies are 6048.0kHz/5241.0kHz, as same as reported in September, 2021, refer to article No.2454.
Their synthetic voice source has changed again and now a female voice is used for broadcasting instead of a male voice.

Amano, thank you for your up-to-date information for the LSB transmission.
Also thanks to Ary for your confirmation.

The LSB frequencies for September have been ceased since October 1.
The updated LSB frequencies are 5360.0kHz/5707.0kHz.

Schedule as of October 2:

Daytime Nighttime
0000-1000 1000-2400
-----+-----------+-----------+--------------------------------------
USB 6408.0 kHz 5241.0 kHz [male voice with slower speed]
LSB 5360.0 kHz 5707.0 kHz [female voice with higher speed]
-----+-----------+-----------+--------------------------------------

The USB transmission still heard on their September frequencies.



Re: CHINA : VC01 (04) - Pigmon Oct 02 (Sun), 2022 23:53 UTC No.2571
Dear XYZ,

I have wrote at the same time without knowing your recent post.

Isn't 5630kHz LSB which you mentioned 5360kHz ?
Currently their LSB transmission can be heard on 5360kHz.



Re: CHINA : VC01 (04) - XYZ Oct 03 (Mon), 2022 01:08 UTC No.2572
Thanks Pigmon.

Did you see the video above?
I wrote it exactly as I received it, so maybe things have changed since then ?
Occasionally they change frequencies several times.

** Check date and time.

Re: CHINA : VC01 (04) - Pigmon Oct 03 (Mon), 2022 16:57 UTC No.2573
Thank you very much for your quick comment on it.

Sorry I did not play your video because the screenshot shows "6.408000" plus "USB" only,
however that includes 5630kHz other than 6408kHz recording actually, confirmed on the YouTube.

On October 1 it was heard on 5360kHz(LSB) at 1030 UTC, however unstable at the time.
Heard also on the frequency at 1029 and 2341 UTC on October 2.

Agree with your estimation on the frequency change.

Probably they switched their frequency in short time range several times around 1000 UTC
on October 2, between 5630 and 5360 kHz.



Re: CHINA : VC01 (04) - XYZ Oct 03 (Mon), 2022 21:04 UTC No.2574
Thanks Pigmon!

I agree too. It was very unstable.
Maybe they were looking for frequencies to use. :D

BTW, your monitor is very helpful.
I hope to work with you in the future !

Re: CHINA : VC01 (04) - Pigmon Oct 10 (Mon), 2022 14:52 UTC No.2582
The USB frequencies for September have been ceased since October 5.
The updated USB frequencies are 7207.0kHz/5241.0kHz.

7207.0kHz, noted at 00:30 UTC on October 5, is as same as for Daytime in September 2021,
refer to article No. 2462. However, 3008.0kHz used in Nighttime in September 2021
does not appear at present. In stead it is heard on 5241.0kHz on October 9 and 10,
that frequency is as same as for last month.

Also, a faster speed female voice has been reinstated for the USB transmission since October 9,
replacing a slower speed male voice.

October-2022 schedule (as of October 10):

Daytime Nighttime
0000-1000 1000-2400
-----+-----------+-----------+----
USB 7207.0 kHz 5241.0 kHz
LSB 5360.0 kHz 5707.0 kHz
-----+-----------+-----------+----

I have searched for VC01 frequencies since August 2021 and the complete frequency list
has been reported every month over 1 year, refer to Nos. 2454, 2462, 2469, 2473, 2477,
2484, 2502, 2508, 2510, 2525, 2532, 2534 and 2537.
Therefore, I finnish monitoring for VC01 this time. This will be my final report.

Dear XYZ,
I am happy that you have returned to monitor the VC01.

I apreciate your providing a thread where anyone can freely report monitoring results also for
such special and purpose-unknown broadcasts.

Many thanks!

7207 kHz, 19-10, 1657 UTC. Good audible in the Netherlands and very loud in Taiwan

7207 kHz, USB, 1431 UTC, 22 October, 2022
5360 kHz, LSB, 1431 UTC, 22 October, 2022

7207 kHz would be very good copy, S9+ signal, in the Mojave Desert of California except for BCB interference.

5360 kHz was less strong and had heavy interference from Chinese radar.

Hi Philby,

>6569kHz / 5241kHz
There was a day when they continued to use the frequency without switching frequencies.
Maybe it's their mistake.

6105-USB, VC01 (tentative), sounded like Chinese Military numbers station,
1240 UT, March 11; woman reading
numbers in Chinese; underneath heavy QRM. My audio - https://app.box.com/s/v7kuejtv37z0dw906t57rnls7gdc52c6 .
---------------------------------------------------------------------------

yes, this is "VC01-Chinese Robot".

Either frequency may have moved again, so I'll re-check as well.
Thanks for the valuable information!

Note that yesterday at this time VC01 was on 8049 kHz USB. Today a Chinese military modem is on 8049 kHz USB and VC01 is on 4978 kHz USB. Possibly moved to this frequency to avoid QRM?



Re: CHINA : VC01 (04) - Token Jan 14 (Sun), 2024 14:44 UTC No.2811
Also note the frequency, 4978 kHz USB.  Not 4078 kHz USB as in the chart.

Is it possible that @Brizdx post on 10 Jan was a typo, and the freq then was 4978 kHz, not 4078 kHz?

>4078kHz
I have confirmed this frequency several times, so it is not a mistake and is being used.
However, I could not confirm its frequency yesterday, so it may have moved.
Due to the strong OTHR transmitted around 4978kHz, it may be difficult to confirm at my location.

I'll check again as well.

Thank you for your valuable information !!!
