So I guess really power is between 50 and 125 kW for the stronger signal
(but not optimal connected to the feeder) at Bijeljina, and the other unit
is still the Stubline tiny 10 kW box, which is always 40-50 Hertz less odd
frequency.

I think 7240 kHz is stronger than before but admittedly the frequency
offset is the same.

So it indeed appears to be the Radio Serbia signal on 7240 that is off-
frequency. I just tried to recheck, but again it's basically a mess,
including the het of some 50 Hz. However, I meanwhile noted that 7240 has
also different modulation than 6100, which has again the same audio than
heard from Bijeljina before, rather muffled, not good for speech
audibility as already pointed out in another report.
So the scenario for now appears to be:
1.) Obrenovac-Stubline is on air 1100-2230[-2200 reported by Mauno Ritola,
wb.] on 7240. It appears that recently some upgrades, resulting in better
signals, had been made.
2.) Bijeljina-Jabanusa is on air 1900-2230 on 6100 and 0030-0230 on 7115.
An azimuth of 310 deg. is given for both, indicating that the very same
antenna is in use for both frequencies. Transmitter power has been
specified as 250 kW by Radio Serbia engineering in a phone call by Dragan
Lekic, and I would not start to speculate about lower outputs without
knowing anything about the antenna and its shape, a factor which could
steal more decibels than running the transmitter at lower power. It's
actually a 500 kW unit (C3 version of Brown Boveri's SK 55), but 250 kW
operation started to become the standard here quite some years ago.

Dear ALL,
I've just finished a long phone talk with the technical director of
International Radio Serbia.
For now I have a time to say the actual schedule is:
0030-0230 7115 BIJ 250/310
1100-2230 7240 BEO 010/999 = non-dir
1900-2230 6100 BIJ 250/310
Best regards till tomorrow!
