Decent but complex timesignal, not nearly as good as DCF77 or Rugby 60kHz.

>2. RTZ; 50 kHz; in Irkutsk; 10 kW; 23/7

RFI makes this unusable.

>3. RWM; 4.996, 9.996, and 14.996 MHz; 10 kW for all frequencies; 24/7

Not unusable.

>4. RAB-99; 25, 25.1, 25.5, 23, and 20.5 kHz; in Khabarovsk; 300 kW for

RFI makes this unusable

"BETA", an Omega-like radionav system, not much on air these days,
very hard to dig out of RFI, not very precise when you do.

"Chayka", an Loran-C like radionav system, but the GRIs are
horrible, in particular 8000, because any N*kHz CW carrier
causes long period phase-noise, the better the CW reference
the longer the period.

Never attribute to malice what can adequately be explained by incompetence.
