Some technical issues on this evening's net, but some interesting content as well. Thanks to G0MJW, G0DQH, G0NZO, M0DTS and G0AZQ for participating. Mike has posted a YouTube recording here: https://youtu.be/_cX9dgddeVc. Picture of the evening from M0DTS - his 122 GHz transmit/receive module.

Hi ALL!,
I have had a few problems with my system which is why I haven't joined the last couple of Nets.
One problem has been receiving the sound from some stations using my MiniTiouner-Pro.
The sound would be pulsing and difficult to copy.
Just been doing tests with my station I use vMIX and IPTS in on the Portsdown output to Lime DVB.
Using the Net settings of Sym Rate 333 and FEC 3/5 & H264 had the problem of pulsing sound.
I don't remember having this problem but so many changes to my system and never log them all down.
If I change the settings to Sym Rate 333 and FEC 1/2 sound is good.
It could be a network problem not my expertise will try connecting my vMix computer network direct to Portsdown.
Will try to join the net if I can fix the pulsing sound at FEC 3/5.

Hi All,
Now using FEC 1/2 or 2/3 all OK.
I got confused with Net parameter's used.
Symbol Rate 333 kS
FEC 1/2
Encoding H264

Should be back on the Net on Thursday.

Hi Martin

The net now uses FEC 2/3. We started on the first week with FEC 1/2, but the resulting video bitrate was slightly too low for the picture quality that we wanted to achieve, so we changed to 2/3.

Pleased to hear that things are working at 2/3.

Re: BATC Net on QO-100 - streaming needed

Post by g8gtz » Thu Jul 02, 2020 7:42 am

I'm not going to be able to do the streaming for the BATC net next week July 9th or July 23rd.

Can anyone else take this on - you'll need to practice first and if transmitting on the net make sure the streaming device is not connected via wi-fi!

Offers?

Another good net tonight with 11 of us on. And no technical problems at all! Well done to: G0MJW, G8KOE, G0DQH, HB9DUG, M0DTS, G4HIZ, G7JTT, G8GTZ, G0NZO and G0AZQ.

Remember 8pm Thursdays, 10499.25 MHz 333kS, FEC 2/3 H264.

Picture of the week is from Jules G0NZO, using his phone as the camera and encoder.

Thanks Martin! I'll e-mail you with the stream password, so that you can set it up and test it in good time.
