Ed, ok good to go, I just got back to this to work on the pinout for them and found your post, it is now on order.
Thanks

Hopefully this isn't your issue, but I recently found one of my Pi 3Bs would no longer display hdmi output even though it has for months.   A different Pi worked fine on the same monitor and cable.   Since ssh was enabled I was able to communicate with it and tried all the stuff you find in the FAQs, knowing it wasn't just a config.txt setting because there was no video at startup which comes from the bootloader not from Linux.   Google searching confirmed that random hdmi hardware failure on the Pi is not unheard of.   Since the composite video works and the published documentation doesn't show anything beyond the hdmi connector I'm not optimistic about being able to fix it, but am open to suggestions.

Thanks Ed, now to figure out if it is the Kantronics or 9800 style they have listed, nothing specific stated for 7900.

Dummy me I knew that, guess I was thinking I had a TNC-Pi9K6.
Thanks

You need to use the 1200 port on the radio. The other is for high speed packet and won’t work with a TNC that isn’t made for it. Otherwise all is good. 

OK I am thinking of trying a TNCPi with a ft 7900r, the pigate site shows the pinout for a FT 2800/2900 using the mic port. My question is my 7900 has a rear data port why can't I use it? Her is a comparison of the 28/2900 mic pinout and my plan for my 7900. Do I need to figure out and use the pinout for the 7900 (MH48A6J) MIC PORT instead? Below left mic pinout from website, Below right my plan for 7900.

Not all HDMI cables are created equal, try different cable. One of the locals here just found that out yesterday.

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

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.

I downloaded both files....
  HamPi_v1.....size 3.8GB
  HamPi Imagev.1.0.torreent.....size 38KB

I cant get it in to the etcher to flash either files......I am very new to raspberry pi.

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.

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.

Is there a way to send W3DJS a small donation for this excellent work, I owe the man a pint at least!

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!

I don't know what you are downloading, but there is no BZ2 file in this

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.
