Voice of the Broad Masses of Eritrea - Programme 1 was observed on the
off-channel mediumwave frequency of 950 kHz (WRTH indicates this is an
'alternative frequency') at 1820 UT on 31 July 2017. Typical HoA music
followed by vernacular news and sign-off with choral anthem, finishing
at 1832 - transmitter switch-off was at 1836. This was monitored with
fair to poor reception via a remote web SDR in Oman. Signal on
(parallel?) 7150 kHz was too weak and noisy to confirm ID in the time
available.
Incidentally, this Oman receiver gives good round-the-clock
reception of the Saudi-based Radio Sana`a surrogate on 11860 kHz - it
can be accessed via the portal at <http://www.sdr.hu>
(David Kernick, Interval Signals Online, dxld Aug 1)
re SAUDI ARABIA / 11860 kHz Yemen Radio relay via ARS.
Thanks to tips of David and the Brazilian DXer,
to use Oman and UAE remotes for monitoring,
concerning TX switch overtime around 1753 ... 1757 UT daily,
I checked 11860 kHz channel between 1755 and 1800 UT
today on Aug 4th.
At remote web SDR in Doha Qatar the signal was straight S=9+10dB
til SWITCH OVER at exact 17.57:59 UTC,
when a very poor tiny signal left on that channel
as tiny S=3-4 level in Qatar SDR remote post.
So, - as assumed already,
Jeddah site in distance close to Yemen is used at local daytime
04.00-17.57 UT,
and Riyadh site at night time at 18.00 to 04.00 UT,
with different antenna characteristic,
latter in order to cover Yemen at Sana'a
and on southern peninsula tip Aden too.
