Thanks To All,

Wasn't expecting to get such a large number of responses......   thank you all.
I have a lot to ponder but also realized that there are options out there making the Pi is such a diversified product.

Everyone, thanks again.

It doesn't take long to compress a file before offering it to folks to download. That only makes sense and I guess I send the message as did others for the same reason.

The successor to the "W3DJS Raspberry Pi for Ham Radio Image v2.0" is "HamPi 1.0" which has an expected release of next weekend -- one week before Field Day.

HamPi is compressed using "XZ" and the compression process by itself takes 45 minutes, but results with a 3GB compressed image file. Fortunately, decompressing it is a fraction of the time to compress.

Hello Dave,
Thanks for your job.
You're welcome!

I have just made the 32Gb card, using Win32DiskImager under windows 7 and works like a charm on RPi4 4Gb.
Before eject the card, I have added the empty ssh filetext at the root of the card to permit a ......ssh connexion ( :) ) at first boot
This is not necessary. Both W3DJS v2.0 image and HamPi image come with SSH Server enabled.
Thanks to the forum, I got the RPi ok on my home network ( I was confused with the hotspot dand did not understand why the dhcpcd.conf file was empty :) it is always the first file I edit when run a RPI card for the 1st boot. Maybe a readme file could be a good idea).
HamPi has removed the WiFi hotspot. It caused too much confusion. And I have added a README with the file download and also on the HamPi Desktop GUI.

I will install at first step : ( maybe some ideas for your future V3 ... ;) )
DSD FastLane

RTL_433 ( receive meteo stations and some other devices such as the tires pressure of the cars on the road in front of my home :) , funny...

Kalibrate ( or calibrate ) to get the PPM correction to apply on the USB Sticks.
https://github.com/f5gkw/kalibrate-rtl

for ADSB ModeSmixer2 and Virtual Radar Server (VRS) ( search google)

For pocsag, a beautfyull job : see https://github.com/pagermon/pagermon
These are great suggestions. Would you mind taking one more step and adding *ONE* issue per program suggestion to the Issues page for HamPi? Its URL is https://github.com/dslotter/HamPi/issues Thank you.

Another application about pocsag Flex hermes and so on exists, "Boswatch "but I met some bugs ( with Python, SQLand PHPmyAdmin in their new versions), and I stopped to work around.

Hi Again.

I needed to upgrade my HackRF one since it was in a drawer since years. :eek::eek:
I got some error about the compiler.( Cmake .. errors path etc.)

The solution is : apt install gcc-arm-none-eabi
after this install you can run the Cmake to obtain the firmware file .bin


I propose another pleasant app to get remotely infos about the system : WEBADMIN (sourceforge)
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python
wget http://prdownloads.sourceforge.net/webadmin/webmin_1.890_all.deb ( or newer version)
sudo dpkg --install webmin_1.890_all.deb
I am not adding WEBMIN to the image. However, you are welcome to customize your own image with it.

access via http://IP:10000 or hostame:10000

do not worry about ssl message ( invalid certificate)


Hope that could be usefull.

Thanks again,

David,

Don't worry about the W3DJS v2.0 image anymore. HamPi is its successor and, God willing, goes live next weekend. It will be seeded via BitTorrent and also be available via direct download.

Berryboot allows you to boot many different raspberry pi programs without having to change the SD card. I bought a large 256 GB USB Flash
drive which contains my many programs. It uses the small SD card only to start the Raspberry Pi so improves
the SD card's lifetime. I was able to ask Alex to add the SDRplay software to his site several years ago so I can use my SDRplay SDR receiver
on my Raspberry PI. With Berryboot I am able to use my Raspberry pi to play games, use my SDRplay, run ADSB programs and even run versions
of Window software by just rebooting into Berryboot and picking which program I want to run.

Pete,

The Raspberry Pi "as-is" does not have a microphone input, so you're going to need to either a) get radio with USB sound card (Icom IC-7300 is what I use), or b) a USB sound card dongle or c) Northwest Digital Radio DRAWS(tm) board. While I'm not aware that DRAWS(tm) has sound in, it does have two connectors for radios which I would believe could carry sound.

Re: Raspberry Pi On-Board Audio?

I imaging you want a wide sampling soundcard to get the broadest waterfall. Correct?  If so, you need to look for 96 or 192Khz soundcards that are compatible with Linux.  I did a LOT of researching (I would have to dig for all my notes, some experimentation with say an old SoundBlaster X-fi, but the results were always pretty poor for me.  There are some custom designed sound devices that offer a flat 192Khz of stereo audio in but they aren't cheap.  Here are some links:

   http://www.telepostinc.com/soundcards.html


After experimenting with I/Q sound cards and their resulting very strong DC spike, I then tried RTL dongles which gave me a much wider 2.4Mhz waterfall, much better signals, and reduced DC spike.  I then moved to an Airspy R2 unit with a 8Mhz wide waterfall, very good dynamic range, and no DC spike and I've been a very happy user since.

You can get "stacking" header connectors.  They have longer pins.  You put the larger board on the stacking pin header, plug that into the pi, then the RTC can go on top of that

Thanks Bob,

I will give that a go first, but I like the board that Dave has mentioned, which poses another question.
I would have a RTC occupy the first couple of header pins, so, if I was to go down that road and put this card in (  https://fe-pi.com/products/fe-pi-audio-z-v2),
how does one put additional components on if the header pins are already taken?
