V24 logs, February 2019
« on: February 01, 2019, 1603 UTC »
On 1st February, there was no transmission at the usual frequency/time of 6310 kHz AM at 1530 UTC. So more of a non-log in this case. I checked on the "soy sauce" kiwi SDR in Chiba, Japan and the KPH kiwi SDR at Point Reyes, California, along with my own Rx. No carrier or any other copyable phone transmission detected.

5290    03-02-2019 1430z V24    AM                       
South Korean numbers station V24, YL, KK, K-pop intro music, fair to strong here in the Mojave Desert of California.

6310 kHz not heard at its scheduled time of 1530z.  Which is opposite of last month, when 5290 kHz was not used, and 6310 kHz was.

The K-Pop intro music is interesting, but I liked this station better when it used martial and traditional Korean music.

Glad someone was checking. I was under the influence of a terrific head cold and switched up my listening station, thus making it so that the preset recording of 5290 didn't take place. Since there was nothing on 6310 on the 1st I wasn't expecting one on the third nor will I on the 8th.

Token, could you do me a favor and repost your V24 prediction chart? I found it to be very handy to have that right in the log post for January. Thanks.

Sure thing.  The latest one I have online is always at the same URL, I update it whenever I create a new one:  http://www.tokenradio.net/Radio/SharedFiles/NumbersTfer/V24_M94_latest_sched.JPG

Or embedded it is here:


My automated recordings run daily, regardless of if I am around or remember to start them or not.

I have an RBASIC program that cycles a dedicated receiver every 3 seconds to all of the past used V24 frequencies from 1100z to 1700z every day.  It plots the AGC value (signal level) each scan cycle to a .csv file, so I can plot / visualize it various ways.  If the script detects a 15 dB signal increase (above plotted background noise averaged across frequencies +/- 2 kHz from past carrier freqs for a specific period to avoid transient noise or false starts) it then starts an SDR recording of that frequency.  The SDR recording is terminated when the signal has been gone (using the same detection technique as used to trigger recording) for a specific period (to avoid stopping recording with a temporary signal fade) or when the signal has exceeded a certain age.

A separate SDR has all predicted V24 activity in its monthly repeating record schedule.

Between those two I typically get all V24 activity, predicted or unpredicted, if it is on a frequency V24 has ever used before.  However, it does not find new frequencies, those I still have to find manually.  And as it has been a couple of years since I last found a new freq I wonder if there is an unknown V24 freq in use someplace.

05 FEBRUARY 2019 observations:

V24 was active on 5290 kHz as Ary B notes. I first tuned over at 1420 to find the carrier already present. Transmission started at 1430 and ended at 1442 with sign off shortly thereafter.

No broadcast occurred at 1500 on 6215 kHz.
