New Portsdown 4 Software Release 202008230
Re: New Portsdown 4 Software Release 202008230
I have been working with Martin G4FKK to diagnose his Portsdown problems. The main issue was that he had previously programmed his LimeSDR Mini with the LimeDVB software and, of course, the Portsdown only drives it correctly when set to transmit using Lime DVB,
There are still some outstanding issues that have us mystified, but his Portsdown is basically working.

Hi Dave,
You may not have implemented the WiFi yet but setting it up through the console worked!
Just like most people I don't read the instructions or WiKi when there are lots of buttons to push! (I do use Google though to find manuals etc. when mending things) You could put the manual straight into the SD card and an option on menu 3.
While thinking about the WiFi don't forget the AstroPi3 system that sets the WiFi of that RPi into a hotspot.
I only mention these things incase while resting and relaxing from working on the software you have a lightbulb moment and think of a solution.
I find that can often be the case.
If you need something tested or broken send me a list.

Hello
Do you project to later add the C130E logitech USB cam with integrated H264 encoder ?

Hi Dave,G8GKQ wrote: ↑Mon Aug 24, 2020 5:27 pmI have just issued a corrected Portsdown 4 software release 202008231. In this release, the band and PTT GPIO outputs work without the Langstone software needing to be installed.
If you have already built the software and your GPIO outputs are not working, I suggest loading the Langstone software, or alternatively you can install the fix:Dave, G8GKQCode: Select all
cd /tmp wget https://project-downloads.drogon.net/wiringpi-latest.deb sudo dpkg -i wiringpi-latest.deb cd /home/pi
Still not getting an RPi GPIO PTT voltage in Portsdown 4 Pluto mode.
First I entered the above code and rechecked, still no PTT on pin 40.
Next I used a new memory card and installed Portsdown and Langstone, PTT is OK in Langstone but no luck in Portsdown.

Hi Steve
My apologies. Your lack of a PTT signal with the Pluto caused some head scratching here, but I have now found the cause. My test/development rig has a Pluto buried inside it which has the Pluto PTT relay modification. This was paralleled with the Portsdown PTT relay, so I had not noticed that the Portsdown PTT was not operating.
The next update (hopefully to be released in the next few days) will have the required code to switch the Portsdown PTT on about 8 seconds after transmit is selected with the Pluto connected. That time delay means that the Pluto calibration will not be transmitted.

Adding support for webcams without being able to test them is very difficult. However, I can give it a try if you send me the webcam's response to the following commands:

Hi Dave
Sorry, I don't have yet the C930e cam. (sorry for the C130e ! )
I have asked this question because we need a new webcam for the F4KLO club, and as the encoding delay of the portsdown 4 is very short with the (old) C920 cam with integrated H264 encoder, we would like to keep the same level of performance.
I have also tested the portsdown 4 to 66K with very good results for image, sound and encoding delay. Thanks for your work.

Another issue I have is the time it takes Portsdown/Pluto to stop transmitting after I ask it to stop, I timed it at 18.5 seconds.
Talking to Arthur G4CPE he also mentioned the lengthy delay, this issue may already be on your list.
Portsdown+Langstone is an excellent project, thanks to all concerned.

Re: New Portsdown 4 Software Release 202008230
I am new to Portsdown 4, i have complete the installation with the latest firmware and everything works fine with my LimeSDR mini, the only problem i have is the Inverted Pi Camera Video which is horizontal. How to change it to vertical? Any solution please?
Thank you
Thank you

Hi
It is not possible to rotate the Pi Camera video by 90 degrees. You need to change the mounting for the camera. If you are using a SmartiPi Touch 2 case, the modification was described in CQ-TVThis was described in CQ-TV 267 page 9.
