Re: Screen size of fldigi on a small (3.5") gpio display
Mark Griffith
There is probably a minimum size for the application and the 3.5 inch screen is just too small. You might get more help asking the FLDIGI application team. Mark KD0QYN

Moving the screen around I can see part of the top of the screen, but can't see the bottom third. This seems like a setting on fldigi needs to be changed. fldigi displays perfectly on a 5" hdmi screen on the pi 3B+ an on a 7" hdmi display. The fldigi loaded on the zero with no problem. Any thoughts??

Also edit config.text and uncomment "hdmi_force_hotplug=1"
(The only small remaining issue is that VNC Connect says it can't display the desktop - more investigation to be done.)

Re: USB Codecs

Hello Phil, I don't have any experience of how the USB audio connection works on a FT991 but if the radio doesn't present anything adjustable in the alsa mixer, all those "audio" level settings are probably adjusted in the FT991 menus. Anyway, this email list is focused on the Raspberry Pi and not X86 laptops as they are going to behave in different and unique ways. --David KI6ZHD

Thanks again David for your reply, No, the laptop uses Alsa audio. Perhaps there's no reason for me to be concerned about the audio input level to the Raspberry pi? I just thought that others might be using a Raspberry pi and an FT-991A together and had found a way to create a level control. By the way, the laptop runs under Kubuntu and the Raspberry runs under the standard Raspberry OS. -- Regards, Phil

Re: Configuring W3DJS V1.0 Direwolf questions.
David Ranch
Hello Dennis,
My latest progress on this Direwolf adventure: David, when I looked at your options I realized that maybe there was a 4th one. The FT-8** transceivers do have bit rates that can be adjusted to other than the default 4800 bps. I tried a few others and found that 38400 works with Direwolf! As soon as I hit that bit rate, the transmitter went into action. Interesting.. so Direwolf is attempting to communicate to the radio at a default of 38400. While I whole heartly recommend higher speeds like this for snappy rig control, 4800bps is usually the default on many radios. At minimum, I feel Direwolf should output what speed it's trying to do CAT PTT control at. On the longer term, this and other parameters needs to be configurable. I've created an issue to track this: https://github.com/wb2osz/direwolf/issues/290 Oddly, I couldn't receive a thing on the APRS frequency of 144.390 Mhz. It seemed to stop working when the transmitter started working. In the end, it was nothing to do with the Direwolf and more to do with hurricane Laura going by the region. The winds had knocked over my two meter antenna on the roof and grounded it. I couldn't see it until I went up there. Ok.. that was problem #2 to solve and you've already fixed that. Good. At present am seeing my beacon on APRS.fi so, at long last, there is some progress. Now I have to study up on how all this APRS stuff works, I know almost nothing about it at this point. At least I am not seeing any red messages in Direwolf and am seeing lots of traffic. Ok.. good. Thanks for all the help, sorry I was such a dummy. The Direwolf manual is a daunting piece of work and I have much studying to do. No doubt there is a log of material in the Direwolf UserGuide and the other great documentation found in: https://github.com/wb2osz/direwolf/tree/dev/doc If you're looking for an APRS Beginner's Guide, I host a copy of K9DCI's excellent guide here: http://www.trinityos.com/HAM/Aprs/APRS%20Beginner%20Guide%20-%20K9DCI%20Ver%205-1.pdf --David KI6ZHD

Reducing size of fldigi display to fit small screen on raspberry pi
Charles Albert
I am using raspberry pi zero w with success, however, it is oversized
and I can't see the whole screen. Is there any quick and dirty way to reduce the display so it fits a 3.5 inch screen?

For the Pi3B that means the root partition of the SD card is bad/corrupt or cmdline.txt is pointing to the wrong device for the rootfs.

Thank you for your reply David, I had already listed the Alsa audio devices but only the default device was shown. I decided to do an update and then turned the Raspberry pi off for the night. The next day and now the Burr-Brown codecs are listed so at least I can select the codecs that I previously had. However I have a new problem, no capture control only an output control which does vary the transmitter power. AlsaMixer reports that "This device does not have any capture controls" . JS8CALL and Fldigi (as well as WSJTX, which I don't use) function but the input is a little high at 60dB. As I type this I now remember that was the case previously but the interface had it's own control which solved the problem. So the question now is, how do I create a capture control? More Internet searching has not revealed an answer. -- Regards, Phil

Re: None of my Pi's are showing on network _ HELP
Mark Griffith
If you changed your SSID and the password, your Pi won't be able to connect unless you reconfigure it. You'll have to connect to the Pi somehow, like attaching an HDMI monitor and keyboard. From the GUI click on the network icon in the upper right, and select your new WiFi and enter the password. Then reboot. It should pop up on your network. If not, something else is the problem.

Re: None of my Pi's are showing on network _ HELP
David Lane
I had this issue.
toggle quoted messageShow quoted text
You said you changed the names - do you mean the Hostnames? Check to make sure they are valid hostnames (that is what bit me). During the boot sequence (after hooking up all the cables etc) it spun waiting to connect because the hostname was invalid and something in the DHCP client didn’t like it, so it just timed out (eventually) and no IP address was assigned. That should all be recorded in your dmsg file. Good luck.

Doesn't make much sense if a clean install or Ethernet connection doesn't show up. Is the PC You are using still on the old subnet so it can't see anything on the router? Is WiFi enabled on the router?
When you say they don't show up, have you logged into the router to see what connected devices there are, or are you just trying the old IP addresses?

Hi Another way to hear that is, you changed you ISP or the old
router needed to be changed out with another one.So I agree we need more information.
