BATC Forum

Just tested tx
SR upto 4000 at 8psk working for me.
contest numbers are also working.
doesnt pick up my station ID. Transmission displays "BATC" instead.
Super to see that it can already TX.

Terry's problem was due to a major bug in the update routine of the Portsdown A27 software. Please do not update your Portsdown on Langstone until I fix it. Later this evening I hope!

Dave, G8GKQ

OK

I have fixed the bug, but you'll need to manually upgrade using the procedure below, or build a new card. My apologies.

• Start up your Langstone and switch to Portsdown mode.
• Log in by SSH
• Paste in the following lines, one at a time:

The Langstone/Portsdown should then update and reboot. You will then be able to perform future updates from the Touchscreen (Menu 3, Check for Updates).

I note that GitHub have been having some difficulties this evening, so you may want to wait until tomorrow to try this.

Hi Dave,

I've done the manual upgrade. I notice 'Check for Updates'' on M3 has 'Force Update' and 'Dev Update' options. Would it help if I tested one or both of those for you?

ciao Dave,
I updated a few minutes ago and got these warnings:

Rebooting

Martin - yes please (if you're prepared to rebuild if it all goes horribly wrong!).

Claudio - Thanks, yes they've tightened up the checking on the compiler since those apps were written. No problems, just highlighting slightly less than ideal programming practice. In fact there are a number of other warnings in my parts of the code that that I am working to avoid by improving the code. All normal!

Thanks, Dave

The update went OK for me but still got a blank screen with all of the LongMynd players. Listening GB3AW

Noel

Both update options worked fine - as far as I can tell. No rebuild required

I'll plug up the Minitiouner next and do some more playing with Portsdown.

I managed to get a picture from QO100 using the VLC player Noel. There was a strong 333 signal on 10499000. Seems to have gone now.

I'm getting the sound from the beacon but no picture.

MER = 6.6 (4.7 needed).

Very wobbly picture but no sound using Mplayer.

Audio but no picture using OMX player.
