Re: GPS
I understand Mark,
My current objective is to determine whether I can operate this unit in the field with a short cable (of course). I'd prefer to mount the GPS receiver to the top of the Pi so keep everything close and tidy. My rig already has enough cables without adding to the cable mess. But for a home station with a Pi running as the station computer, right on. Best... |
Re: GPS
¿ªÔÆÌåÓýIf you are using the little dongle GPS, then an extension cable will probably help.? The GPS antenna must have a clear view of the sky to have a reasonable signal strength.? In addition, the farther it can be placed from the noise of a USB port, the better the s/n will be.? USB 3.0 ports are the worst offenders.? Use an extension cable and pot that GPS antenna in a window where it can see the sky, or try one of these:https://smile.amazon.com/gp/product/B086ZK6R89/ It has a long cable, and a magnet on the bottom so it stays put on a magnetic (steel) surface.? I have used this model on my pc's for several years continuously 24/7 for timekeeping with no problems.? They are available on amazon from at least 2 suppliers. Mark,? KE6BB |
Re: Help - Hot Spot not working
¿ªÔÆÌåÓýWell, I¡¯m out in the boondocks and I fired it up. Saw and connected to it. Rebooted and never saw it a again. When I return to broadband, I make a new build and install just HotSpot tools first, then test it. I¡¯m going to set up the connection for to WiFi to an access point I can easily shut off rather then my 6 node mesh network.? On Aug 17, 2020, at 4:56 PM, Bill Dornbush <bill@...> wrote:

Re: Help - Hot Spot not working
More investigation...
I have a Pi 4 also with BAP and when I ran Hotspot Tools on it, it showed an SSID and Password, and it works just fine. I poked around a bit, and found /etc/hostapd/hostapd.conf In this file, I can see ssid and wpa_passphrase that match what I saw in Hotspot Tools. So back to my other Pi, which happens to be a Pi 3 but I don't think this matters. When I open /etc, there is NO hostapd directory in it. I notice other differences.? On the Pi 4, when I select Undo Force Hotspot, the Pi 4 switches back to the LAN just fine. On the Pi 3, when I select Undo Force Hotspot, I must reboot before it switches back to the LAN. On the Pi 4, I have Hamradio > Hotspot Tools in the menu.? On the Pi 3, I have Other > Hotspot Tools in the menu. I would surmise that I need to restore some pieces in the Pi 3 including getting hostapd restored.? What is the best way to do this, short of reformatting and starting over? -- --Bill AA6BD |
Re: Help - Hot Spot not working
I am experiencing the same problems as others have related.? I am running BAP 3.0.2?
A while back, I tested this and it all worked fine so something has gone astray. I ran? bash ~/pi-build/diagnostic and will email this as directed. When I run Hotspot Tools, the SSID and PASSWORD are missing. When I run Change Name/Password and enter a name and password, they do not appear after reboot and when I run Hotspot Tools again.? Obviously, I cannot connect to a hotspot of 10.10.10.10 without an SSID and Password. -- --Bill AA6BD |

On the Window side, Winlink Express through UZ7HO does not work. Yet works with vara fm according to this website? I'll load up the pi and Setup Dierwolf? Thank You Don va7dgp Thank You? Don Poaps

David, ? ? I have an extension cable running from one of the USB 2.0 to my window. I also. Have a ferrite bead at each end.? This has been working flawlessly for a week now.? I also have been running gos on -n for a few days and I have been changing different things plugged into the USB ports. Only thing I found that effected the gps was a Bluetooth dongle for a wireless keyboard that I have.? Bryan, NU8J?

Re: GPS
Bryan,
You're welcome! Learn to love the command line. It is a very powerful tool and very unixy. I've had gpsmon -n running in a terminal window for over a week. I've been testing the GPS for my station computer and want a reliable source for time without having to rely on the Internet. 73 de AG7TX |
Re: Weird GPS problems
The Pi4 has been running since my last post and been stable. The GPS will occasionally drop its lock when the satellite constellation does not favor its location, but will pick up the lock again once the signals from four or five birds are strong enough.
This morning I decided it was time to backup the SD card in the Pi4. So I mounted the USB adapter for another micro-SD to one of the USB3 ports and fired up Jason's utility to make the copy. As soon as the copy began, the GPS lost lock. I waited for the copy to finish and then watched gpsmon to determine if the UBlox would reestablish lock once the copy process completed. After about 15 minutes I decided it was not going to happen. I pulled the adapter and waited. After a few minutes, the GPS lock was reestablished and time and coordinates resumed downloading. That's interesting. I have another USB dongle that will accommodate a micro-SD card, the unit on the bottom. I believe this unit is USB2. I put a card in this unit, plugged it into the same port as the previous attempt, and started Jason's utility. The copy commenced and completed without interrupting the GPS lock. Once the copy process completed, I left the unit in the USB3 port and watched for awhile. There was no change in the GPS lock. That leads me to think that the problem is either this particular USB3 card adapter or the USB3 operation for copying the card is causing interference with the UBlox GPS receiver. I don't have another USB3 card adapter in my inventory, so I do not have another unit to test. I don't mind buying another to continue testing, but would need a recommendation so I just don't buy *something*. So, at this point I'm open to suggestions for an alternative USB3 card adapter to test. As I write this, the UBlox is dropping out and then regaining signal. The SNR for some of the satellites is probably the issue. I have not yet looked at the constellation. The good news is that the daemon will reinitialize the GPS receiver and regain the time and location lock. |
Re: DRA 36 Sound card
This only works on Linux so it works on Raspberry Pi but is not supported on Windows. It describes how to use a C-Media GPIO pin to control PTT.? No wiring is needed other than the USB connector.? I use this with my DRA-30 card and my Raspberry Pi and it works great. You must install the optional?libudev-dev then recompile Direwolf.? There are instructions in the User Guide on how to do this. --Bill AA6BD |
Re: Hamclock 2.510 vs 2.51
William MacLachlainn
If you are starting the process via something like './ESPHamClock-screensize' then it will die with your login process, i.e. when you sign out of ssh.? You have three options if that is the case: 1) start it with `nohup`, 2) start it in a `screen` or `tmux` session, or 3) write a little startup script to start it as a service.? All this assumes that it doesn't have a flag, e.g. -D to daemonize itself when run. Let me know if you have any questions about those.
