There seems to be a problem with the 7" touch screen and the frequency display option. When you come to set the frequency the buttons are not aligned with the touch screen.

Hi Mike
I take it that this is the problem that you are describing:
https://wiki.batc.org.uk/FreqShow#FreqS ... nch_Screen
It is caused by an incompatibility between PyGame (the Python gaming library used by FreqShow) and the multitouch driver for the 7" screen. I have spent hours trying to make it work. I had a choice of disabling the functionality all together, or including it in "Cursor and trackpad" mode, which is what I chose to do.
You're welcome to try to find the solution and I will happily incorporate it if you can.
Dave

Hi Mike
Please could you try the new solution to see if it works? The second link seems to be talking about a different screen.
Thanks
Dave

There seems to be an issue with the BATC streamer menu text; it overflows both sides of the button.

Thanks Steve
I hadn't spotted that. Cosmetic only (I hope), so I will fix in the next release. Added to the bug list!

New Portsdown Stretch Software Release 201807090
I have just released a some significant improvements to the configuration of the LeanDVB Receive software in the Portsdown. Using an RTL-SDR, it will now receive strong DATV signals throughout the full frequency range of the RTL-SDR (including 71 MHz without a converter) at symbol rates from 66 KS up to 2MS. At Symbol Rates of 1MS and above the Constellation and Parameter overlays should be turned off to conserve CPU resources for the receive decoder. On deselection of receive, the system occasionally locks-up and needs a reboot, but I have managed to reduce the likelihood of this happening from previous software versions. Clearly, smoothest results are obtained using a video monitor (not HDMI) plugged into the RPi or the Element 14 7 inch screen.
Full release contents:
- LeanDVB Performance Improvements
- Bugfix BATC Streamer label
- Bugfix LeanDVB Preset storage

Hi Dave
I began an update of my Stretch card in the Portsdown last night. It was connected by cable to LAN. Power was a 3S LiPo because I was in the house to get full strength internet. I noticed an hour later that it hadn't progressed further than 4 out 10 fourth X. To save the £40 battery I had to turn off the Portsdown. It's cheaper to redo the software! All the updates to date have been brisk 10 minute tasks. I hope no-one else has the same problem. Note to self - do save the settings to a USB memory stick per one of the menu settings.

I am just updating now. It has got to stage 4 almost instantly. I will see how long it takes for me.
Dave - Can you provide some feedback for the touch screen button press as at the moment I think it goes off to check and that can take several seconds so it's not clear the button event has been registered.
Mike
So it locked up and lost access to WiFi or the other way around perhap. On connecting Ethernet and logging in I see:
Webcam device name is none
Video capture device name is $f▒v
No Touchscreen found: No such file or directory
Using the menu I can get back the ncurses screen and then update using the console which is a lot more informative (maybe this could happen on the touch screen?)
The problem was in dpkg. It advises running 'sudo dpkg --configure -a to fix it. I have done this and re-started the upgrade. I think it just takes a long long time.
