52.5E (Yahsat 1A)

We are both in a similar boat regarding the footprint, the signal has just come back in, after further reading no wonder i cant lock this one, ACM/VCM,

Hi all am receiving the bird with a 90cm for the Mena Beam and 150cm offset for Eastern Beam. as for the 12034 V on the Eastern beam I will need a 240cm offset coz they are under the DVB S2 Qpsk mordulation.

12168H(fox) switched to east beam.

Thought to share this ... I know that reception of the MENA and East beam might be nothing special for some of our friends in the eastern parts of Europe but for my location and western of it it is somewhat of a challenge.
Not all EAST transponders lock here with 3.4m but ... I am quite happy. :)

A scan of Al Yah 1 at 52.5 East today resulted in all four of the MENA beam frequencies being locked but nothing from the East beam.

One of the MENA beam frequencies (11977 H, SR27500) has quite a decent overhead with respect to the signal level required for a lock.
The other three frequencies on the MENA beam are all with FEC of 5/6 and modulation of 8PSK so require a theoretical 9.4dB to lock.

The list of MENA beam frequencies locked is below, followed by a few pictures.

1. 11977 H, SR27500, FEC 8/9, Modulation DVB-S2 QPSK, SNR to lock 6.2dB
2. 12054 H, SR27500, FEC 5/6, Modulation DVB-S2 8PSK, SNR to lock 9.4dB
3. 12130 H, SR27500, FEC 5/6, Modulation DVB-S2 8PSK, SNR to lock 9.4dB
4. 12169 H, SR27500, FEC 5/6, Modulation DVB-S2 8PSK, SNR to lock 9.4dB

Somewhat favourable reception conditions recently from the East beam.
