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.

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.

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. https://youtu.be/QI-w9rQFn40 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 !

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.

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.
