5.7GHz good to go Just hoping Marcel can edit DVBS2-GUI to use the full Pluto RX range before the weekend.
No changeover relays were harmed in making this. It will also work as-is NB directly with the Langstone
Cross-bar bolts to my Surveyors tripod.

Re: IARU Region 1 ATV Contest 13/14 June
I plan to be QRV on 146.5MHz (5W to 8ele horizontal) and 23cm (50W ish to a 44 ele) from JO02cg if anyone would like to try.
I will put out a test card at various times on 146.5 and 1255MHz system DVB-S H264 333 FEC 2/3.
Unless anyone can advise me on more appropriate system settings as I'm new to terrestrial ATV
Contact me for a skeds 01223 862480, @g4bao on Twitter, via the ON4KST GHz bands chat and I will leave the SSB RX on 144.750MHz TV chat frequency. Manual changeover of antennas between SSB and TV, so give a few calls, I may be transmitting TV.
Also QRV on 23cm SSB with 200W to the 44ele for sked setup.
Hope to make a QSO!

Re: IARU Region 1 ATV Contest 13/14 June
I should probably add that with some wire pulling and cable swapping that I can receive on
10370.5
3402.5
and 24049.0 MHz
using my terrestrial transverters if anyone wants a cross band QSO.
Not quite got round to TXing on those bands yet, but it's just a matter of switchery and drive levels from my Portsdown
Again, call in the places described in the previous post or in fact I have Zello as well

John,
Talkback on 144.750MHz is usually FM; if you can't make a 2m FM contact, you won't be exchanging TV pictures!

I will be on from home in IO91RV. Two way on 1255MHz analogue/digital, two way 437MHz and receive on 146.5MHz.

Hi John - I don't think we have a good enough path to work but I suppose we could test that on FM - my antennas are all horizontal beams though so I need to be pointing the right way for talk back.I have zello too. I am not set up yet, that's this mornings job. Had a lie in after completing those tiring Monday to Friday tasks you can now only dimly remember.g4bao wrote: ↑Fri Jun 12, 2020 10:42 pmI plan to be QRV on 146.5MHz (5W to 8ele horizontal) and 23cm (50W ish to a 44 ele) from JO02cg if anyone would like to try.

As for system settings I have been experimenting with low rates but for this contest maybe DVB-S2 at 333ks 1/4 rate or 125ks 1/2 rate will be sufficient for sending a contest exchange. Maybe even 66ks without audio would do. Awful pictures unless you use H265 but good enough for a static image with 4 numbers on it

[Thanks for that Shaun. wasn't sure. I can of course do FM :-0 !
Do people use H or V pol on 144.750 FM?
