Title: RU chatters 3 MHz band 2205 UTC 18 Sep 2019
Post by: kris on September 18, 2019, 2226 UTC
~`2205  Russian chaters (5 region) good heard tonight at 3083 3105 3136.5 AM
Usually, wide bad modulation, they use  nicknames only like Bakłażan, Sobol, Anton, Braslet

I've heard these guys on several Russian based SDRs (KiwiSDRs).  They're very active from 2 MHz to 3.5 or 4 MHz or so, the 2.5 MHz or 2.6 MHz to 3.3 MHz area seems to be the busiest though.

Here's a log from December 2018:

3053 kHz - Russian or Ukrainian OMs chatting, very good signals, one of the transmitters is on 3053.1 kHz, another one 3053.5
3073 kHz - S9+10db very good signal, 10-15 kHz wide AM, two ops, one on 3073.2 kHz, the other on 3073.4 kHz
3086 kHz - distorted audio, but strong signals, several stations chatting, one is on 3088 kHz, another on 3085 kHz
3100 kHz - more strong audio, with the usual frequency variation and wide AM signals
3113 kHz - very busy, more CB-like chatter and some dead carriers too, one on 3113.4 kHz
3120 kHz - another busy frequency, with lots of variation in frequency, one guy was down on 3117 kHz
3131 kHz - 3132 kHz vs. 3130 kHz, two replies to one transmission, you can see one of them swing up in freq. when the mic is keyed
3144 kHz or 3145 kHz - more of the same, 2-4 MHz Russian AM traffic...I wonder if these ops are using surplus military gear
3156 kHz - VERY strong (S9+20db) signal 3156.9 kHz at 2213 UTC (0013 local time) QRM from 3160 kHz
3160 kHz - weak carrier with some modulation, getting obliterated by the 3156 kHz / 3157 kHz crowd
3185 kHz - carrier on 3185.1 kHz, good signal with strong modulation, reminds me of 27025 AM when the band is busy

Apparently its either fishing trawlers using older-generation AM voice gear, freebanders/outbanders using old military gear, or some combination of the two.  The AM signals are generally pretty wide, and there's often a good kHz or so in difference as far as carrier frequencies go for a given QSO.  Both of those would indicate that they're using older radios with analog tuning.  I've heard them many times since on the various Russian SDRs, but I haven't logged them. 

It's like CB, they're almost always there! 

Messing around with a Russian remote receiver this afternoon, particularly the 11 meter band (which is quiet) and the 2-4 MHz border region between MF and HF, several posts here and elsewhere on the Internet have indicated to the use of so-called village radios in certain parts of Russia.  So, as always fascinated by bootleg two-way communications on weird bands, I decided to do some more monitoring.  No, I don't speak Russian.  Most of these transmissions, especially the ones in AM mode, are off-frequency.  Indications are that many of these folks are using surplus Russian military radios.

Logs, starting at 1600 UTC September 5th, 2017 (1900 Moscow time)

2880 kHz USB - Russian language
2900 kHz USB - Russian language, right on frequency, chatter similar to the 3 MHz AM signals
2915 kHz AM - Russian language
2920 kHz USB - Russian language, S5 to S7 signals nice audio
2995 kHz AM - Russian language, with QRM from 3000 kHz traffic
3000 kHz AM - Russian language, nearly nonstop traffic
3025 kHz AM - Russian language, several OMs talking, very strong (S9+ with powerful modulation)
3055 kHz AM - Russian language, weaker than 3025 AM, peaking at S4-S5, very chatty
3065 kHz AM - Russian language, all radios off-frequency
3080 kHz AM - Russian language, OM chatting very rapidly, strong AM signals S7 to S9+30db
3090 kHz AM - Russian language, OMs and YLs talking, most stations are off-frequency (3089 kHz, 3091 kHz, etc)
3105 kHz AM - Russian language, some with minor overmodulation, S9 to S9+30db very strong
3110 kHz AM - Russian language, lots of QRM due to signals squeezed together around 3 MHz
3115 kHz AM - Russian language, causing serious QRM to 3120 kHz AM and vise-versa (two QSOs going at once)
3120 kHz AM - Russian language, radio checks, very powerful AM signals here (strongest one S9+20db)
3125 kHz AM - Russian language, weak, getting killed by 3120 kHz
3145 kHz AM - Russian language, one station on 3144 kHz talking to another on 3147 kHz
3150 kHz AM - Russian language, different QSO from 3145 kHz, lots of QRM
3160 kHz AM - Russian language - signal strength weaker than most other logs
3170 kHz USB - Russian language, with QRM from 3175 kHz AM
3175 kHz AM - Russian language, several mentions of "microphona" and "microphone"
3200 kHz AM - Russian language
3210 kHz AM - Russian language, several OMs talking with strong signals
3215 kHz AM - Russian language, much weaker than strong signals on 3120 kHz
3225 kHz USB - Russian language
3255 kHz USB - Russian language
3320 kHz AM - Russian language, S4-S5 with lots of fading
3325 kHz USB - Russian language
3350 kHz USB - Russian language, with heavy QRM from CW signal on 3351 kHz
3355 kHz AM - Russian language
