TV HDMI #pi

Rob
 

Running the pi with a 20 inch vizio tv out in the shop all is good. Decided to use a 32 inch vizio tv. No signal on the 32 in. When the 20 inch is on I unplug the hdmi cable Then plug into the 32 inch it works.....I did a reboot... then no display on the 32 inch......TNX

Tim,

Thanks!  I will eventually figure it out. Knowing this will make it easier.  I’ve looked at a few basic intro to Linux YouTubes and read a lot of the info at the Raspberry Pi Foundation.   All that helps. The encouragement of yourself and others in this group help.

Downloaded It.
Now wanting to run it as a WSPR node, with SDR Play RSP1 .

Will it be plug and play  ?

Will i need any API to be installed for SDR Play ?

Also any pointers as to how to route the audio from SDRPlay to WSJT X for input to run the WPSR Node

You're welcome.

There are two ways to run WSPR on the HamPi image "out of the box". One is to run the "wspr-pi" application in /usr/local/bin . The second is to run WSJT-X.

The SDRPlay is receive-only. You can not use it to send WSPR.

The SoapySDRPlay drivers have been installed on HamPi. This allows you to use the SDRPlay with GQRX and CubicSDR, for example.

Dave on June 13 you released a version called "W3DJS Raspberry PI Ham Radio Image v2.0"  is that a different program from this version "HamPI 1.0 " released today?
HamPi is the successor to the prior image. It has newer versions of software and is also created by an automated build. It is overall better than its predecessor.

The .torrent file is used to download the HamPi image via BitTorrent. However, as you downloaded the HamPi image which is 3.8GB, you already have it.

Balena Etcher on Windows will flash HamPi to a microSD card "as-is". What is your error message?

By the way, from the included download file, "HOW_TO_FLASH_IMAGE.TXT", it says:
No matter if you are a Windows, Mac os Linux user, go to https://www.balena.io/etcher/ and
download and install Balena Etcher. This is the easiest program I can suggest to use.

1. Start Balena Etcher.

2. Click on Select Image and select the downloaded HamPi_v1.0.img.xz file.
   (If you got HamPi in a tar file, you'll need to extract the files from the tar archive first.)

3. Click on Select Drive and select your 16GB or larger (micro)SD card.

4. Click on Flash!

After several minutes, the flashing process will finish, and you can eject the (micro)SD card
and insert it into your Raspberry Pi and power it up.
Hope this helps.

Re: Getting AP mode to work on the new Ham Pi image

Dave - Thank you for all the hard work to pull this together !

I am sure this topic has been covered many times but I would appreciate some clarification.
I want to use a tablet with Real VNC to talk to the PI.
When I boot the new Ham Pi image, WiFi is turned on and see's other AP's in the area.  It seems to not come up in Access Point mode itself.
When I read the older posts on this list there is  lot of good advice but the older posts say that the PI should boot in AP mode, not in a client mode.
Unless I am missing something, what I see is exactly the opposite. 
The question is how do I put the PI into AP mode for field operating? 
I'm a little late to the party here because there have already been a number of replies to this thread... That said:

You're welcome!

If you want to add AP mode to the Raspberry Pi, there are a number of guides on the web to do this. I didn't do this to the HamPi image because it caused a lot of confusion last time. Most people don't want AP mode, so I'm setting up the image for the majority. That said, here's one guide which I haven't tested but may work for you: https://www.raspberrypi.org/documentation/configuration/wireless/access-point-routed.md Good luck with this.

Don't forget that in Dave's instructions for wifi usage you had to "killHotspot" or some such thing.
These were needed for the prior image, but not the current one. Download HamPi and there will be no need for this workaround.

No, I do not wish financial compensation for this. However, I do have a PDF on the desktop called "GIVE BACK' which outlines two charities I support. I would appreciate donations to be sent there. And the image is also QSL ware, so if you like it, send me a QSL card! And if you ever find yourself in Atlanta, GA, look me up. We'll go out for a pint together!

BZ2 was used for the prior image. The latest image uses .XZ for compression now because it results in even smaller files and shorter download times.

I downloaded the image for the new release of W3DJS OS and software package. I need a bit of handholding to get the files off the W10 machine and into/onto an micro SD card and install it on my RPi 4. I am very keen to get started using this software. It may have been covered elsewhere in a post to the group but I cannot find it. I am reasonably computer leterate but I don't want to mess up and create more frustration. Thanks very much in advance. It would also be good to know if it can support the RTL-SDR dongle. I want to create an online SDR as part of a project for my final year at college. The idea is to build a webpage and somehow embed it in that or have a link available. I am a mature student so perhaps the sucessful installation might inspire some of my class to get into Ham Radio. 73, Tryg de EI7CLB

Yes, the image supports the RTL-SDR dongle, as well as numerous other Software Defined Radios.

Ok guys here's the deal.
He downloaded W3DJS 2.0 NOT HamPi 1.0
In that project there was some work around needed that required you to stop a service in order to get WiFi to work.
The thread that contained the instructions on that had over 10,000 replys so not sure how to get at that right now

Re: Brand New to Raspberry Pi

John,

Welcome to the world of Linux.
The OS you are using is a modified version of an operating system called Debian, that is what etcher put on the card. It has something like the apple/android store built in and it is called apt. That should be how you get all of your programs when you are starting out with a Pi. When you use apt, it's just like installing/updated/removing a program from the apple or android stores on other devices. Out of the box; nothing on there should damage your home directory.

Since your just starting out you might want to think about picking up an extra usb drive to save backups onto too. I generally use a program called tar, it's like zip or rar, and you can compress any/all folders on the system with it, but there are several other programs that are more user friendly now though. Try out a couple of the different ones and see what you like, then grab an extra SD card and try to restore your backup too.

When you want to impress your friends with your "leet skillz," you should try the "apt-cache search <search term>" command from the terminal. Then use "sudo apt-get install <package name>" to install the program(s).

For example;
apt-cache search amazingly awesome linux games
sudo apt-get install nethack-console


Re: CAT Control Options

Bill 3091E N6EF
 

I bought the Valley Enterprises cable for my 857 from Amazon and it works great. It's a bit more expensive than similar cables, but it had good reviews so I took a chance on it. I can use it for rig control with a Pi3B+ and Pi4B using flrig, fldigi, wsjt-x, and js8call. No problems. It keys the radio just fine with CAT control from the applications. I can also use it with CQRLog logging program and the program reads the frequency and mode. The program won't key the radio. I just had to set the interface to be /dev/ttyUSB0 and all the applications supported it.

I hope that helps.

Re: Ham PI 1.0

The hampi v1.0.tar, install 7zip and use it to extract the tar file.  You will then have a 3.6gb .img.xz file.  You select that with etcher and it will write it to the SD card

HamPi has everything and the kitchen sink installed for you. Where as Build-A-Pi is more selective on what apps are installed and allows you to choose which of those apps get installed. Now if the Jason and Dave could work something and merge the 2 that would be something!
