Good morning,
throughout the last few years, I observed this transmission between
approx. 7233.x and 7237.x ... so this is absolutely not surprising. This
transmitter is often on low modulation, and we have observed roughly the
same pattern with the 9560v transmission: always varying slightly on the
one hand, but sometimes also drifting +/-2khz within minutes oder hours,
but likely back to the long term mean sooner or later.

Wolfy,
But in the meantime you had reported this, indicating Ethiopia varied
a lot more than 30 Hz, like almost 2 kHz down. Do you now think this
was really Ethiopia; and my 7235.82 carrier halfway in between?
Glenn
It seems that Ethiopia does vary below 7236, even below 7235. Wolfgang
BÃschel now replies:
``re ETH surprisingly 7234.9v, a pity, just before I could MEASURE
accurate ODD frequency, ETH broadcast left the air exact at scheduled
0430 UT on day=6 Fridays! The transmission was on the low side close
approx. 7234.8 ... x.9 kHz. This Dec 4th 0430 UT morning. 73 wb``

UNIDENTIFIED. 7235.82 approx., Dec 3 at 1405, JBA carrier,
which points to always off-frequency EBC by longpath; or does it? EiBi has
it on 7236.5 at 14-15 as EBC in Arabic; 15-16 switches to V. of Democratic
Alliance clandestine; 16-17 back to EBC in English. Recent report from
Wolfgang Bueschel puts it a little lower, but supposedly not varying down
below
7236:
"7236.372 kHz footprint narrowed - the Ethiopian station
always wanders up and down 20-30 Hertz. Scheduled Radio Ethiopia in Arabic
in 14-15 UT slot, from Addis Ababa-Gedja site. Noted at 1405 UT on Nov 25.
