23.5°E Astra 3B

[dreamsat]

a transponder can be seen horizontally

21904 H 17138

 

[femi]

Both transponders (21512 V and 21784 H) needs a lot of more dB for lock.

 

[John]

A decent signal 21.784 H from the 2.2m PF / Norsat lnb of around 10dB or so, 17 k North of Nottingham UK but no lock.
Signal 21.904 H is only about 2.8-3.0dB with me.

[solly]

[John]

A totally different Hor scan outcome this morning for me here

Signal for 21784 H 17140 on 1.8m from my place...

 

[dreamsat]

my signal at 21784 H 17140 with 2,20m.

Unlock is at 11,6 dB

 

[dreamsat]

The 21904 H has a DVBS2/QPSK mod and can therefore be unlocked with less dB. I think from 6.8 dB. (with 3,70m)

 

[dreamsat]

The transponder also works with 2.20m. Here's a comparison between 2.20m and 3.70m. It's not a huge difference.

 

[Satfaca]

Not huge ... but it is significant.
You have 0.3 dB margin on 2.20m while 1.5 dB on 3.70. In my eyes it is considerable.

 

[stephan94]

and with 1.80 only 4.2 dB

 

[dreamsat]

In the evening is today a little bit better

 

[stephan94]

sufficient signal to lock in today with 1.80
