Dean;
Allan is fine.  Thank you for asking.
I do like the idea of having one battery pack (with appropriate dc/dc buck or boost) to run the rig, Pi, and any other items.  That is an option that I am also looking at.
Again, I am so very new to using a Pi (and even digital modes in general), and am just slowly returning to being a Ham again after "life" got in the way for some years.
I guess I need to consider the pros and cons of a single battery as a power source for all versus separate batteries/sources for the radio, the Pi, and any other items.
These little "backup" style batteries just seem kind of cool in a way but I did not know if they have really been used much in the real world.  Or if they are just gadgets more or less.
Thank you so much for your thoughts and input, and I always enjoy hearing how others approach things.
I am very much in the learning phase at this time.

Lloyd or Allan (which do you prefer)?
I don't have feedback on those items.
I run a dc/dc converter that works well so I can run off the same battery as the rig. I can use the dc/ dc converter power the pi or to charge my ipad or the power brick and, also have tested powering the pi with an Anker "power brick" and that ran the pi for about 14hours (results may vary for you).
I believe  the anker power brick is a 20000mAh. 
my battery is then charged either by commercial mains OR by solar panel from Renogy.

Lloyd A Jones - KD4RUF
 

I am a returning Ham as well as just now coming to the Raspberry Pi party as well.
I have looked at battery options for the Pi and right now I have seen what seems to be 2 or 3 really viable options (although I may have/most likely have missed something).
They are the;
     PiJuice Hat
     Pisugar (mentioned here)
     LiFePO4wered
Does anyone have some real good and real world experience with any of these 3 or others?  I am not looking to run the Pi for days on end, just something to be able to quickly and easily take a full setup outside the house for maybe SOTA/POTA/Camping/Backyard use.
Total noob here (in both using a Pi as well as using groups.io), so please excuse my ignorance.

Do you need stereo input? You can get a c-media mono in, stereo out USB dongle for under $10.  If you need quadrature (I,Q) inputs (from SDR) the cheap one won't work, otherwise it's all you need (and very plug'n'play). 73

I am in the retired category and what used to take an hour to do takes all day now. I am mainly a QRO DXer and Contester. But I enjoy UHF/VHF weak signal work with the IC-9100 that goes from 160 meters to 1.3 GHz. Been a ham for a long time, so I have collected a lot of equipment over the years. I have 2 stations, one here at the house and another at our farm. I need to do a lot of antenna work but I cannot climb anymore.

I sold the KX2 and bought a X6000A antenna, LNR OA-6 6 meter loop antenn, two 50 ft rolls of LMR-200 and a pre-owned G90 with the optional fan/base.  The LMR-200 is for VHF/UHF.  For the past 50+ yrs RG-58/U,, RG-8X has severed me well. If you are running 1-500 watts you don't need the high priced stuff unless you are 100 ft or more away from your antenna. Sure you might lose a db or two or so, but in the end your RX (that includes the G90) is hot enough to hear most anything, including most if not all weak
signals.  At 73 with failing hearing I could not hear a very weak signal if my life depended on it.

The G90 is a wonderful radio. I am now working on it making nice to my Rasperry Pi 3B, thanks in large part to Ham-Pi. This group has been very helpful  David has also jumped in and that made my day, week and year. He is one talented programmers and did one hell of a job creating Ham-Pi.  My soon to be RV take it with me set up with the Pi3B+G90+a few different compromise antennas.

So in you case, pick a coax you can afford and the best quality you can find. Put up a G5RV, or a tuned dipole or a nice 4 or 6BTV vertical and have fun. Just remember the lower the power, the more compromised the antenna the sweeter the DX contact is. Having a tower with stacked mono banders and running legal limit will get DX with a yawn.  5 to 20 watts CW or SSB with a "compromise" antenna ROCKS. Having a RPi just makes it all the better....

Re: PSK-31 on Pi-zero

Harry,
I've never worked so hard being retired. Since I bought the ranch, not the farm. Being on Fixed income as well, I think a caveat needs to be repeated far and wide with regards to being frugal as in ham radio operations.
#1. Buy the RPI version according to NEED..ie:
      a. Making an ALLSTAR node? I have 7 "on the air". HAMVIOP requires only a 4Gb SD card and I have 2- 24x7 running
          repeater ALLSTAR NODES and both are Raspberry PI 2's.
      b. Extra Horsepower and memory is not needed in a dedicated application. So why buy a RPI4-4Gb and 32Gb SD card.

The biggest pet peeve of mine is not with RPI's and hams but with coax and hams... So many hams believe the only coax they should use is LMR-400.. Then they run a copper J-pole at 25 feet with 35 feet lead in to the radio. I always reference them to QST October 2017 pages 71-71... 
Simply stated I like the way they explain coax losses in 1dB per a footage for a given band- Example 2 meters:
LMR-400    -67 feet
RG-213      -38 feet
RG-8X        -27 feet
RG-58        -18 feet
RG-174      -10 feet
So at 35 feet lead in - LMR-400 is 0.5dB but RG-8X is  1.3dB.. So using less expensive easier to handle RG-8X. the loss is only .8dB more. No one can hear 1 dB loss, only lab equipment can measure it. Yet the cost is 3 times as much. Even RG-58 is only 1.4dB loss totally acceptable.

Hello Vic

May be worth giving it another go with a different Pi, here I have no problem running psk via Fldigi v4.1.01 and Flrig 1.3.42 on a Pi3A+ the software was downloaded from PiOS Add/Remove Soflware default repositry list. I have the Pi connected to a Timewave Navigator interface, which also provides a WinKeyer interface in Fldigi, connected to a Kenwood 590s. Appears to be little resource load when running the applications and I connect to the Pi using VNC Viewer from other devices for remote operating.

Re: Distribution?

Pacman is SIMPLE...(really...by design).

Um, you can go to the wiki at archlinux and learn about it and (my)
preferred pacman manager; "yay" .

I *should* let you know that I run MOST of my ham radio stuff on rpi's
running raspian HEADLESS and vnc'd into my Desktop rpi. BUT, if
raspian can run a ham radio app,, then manjaro (arch-linux) should be
able to as well. Just a simple change to the PKGBUILD for each
package, which we can go over in a private email.

(In fact I run 5 rpi's in my office/shack along with two chromebooks;
neither of which run chrome os, but rather archlinux.)

Finally, so you can understand WHY I run manjaro (or it's parent
distro- archlinux); I helped with archlinux way back when the package
manager was being designed. It suits ME, and mainly because it is
SIMPLE, yet COMPLETE. (And yeah, many other people also find it to be
what they want to run as well as having the MOST packages available in
the linux world, and the most complete wiki.)

Re: Distribution?

If you want a genuine Debian Buster 64 bit or Debian Bullseye 64 bit go to

https://raspi.debian.net/tested-images

and download your preference, put it on an SD and boot it. You will boot to the command line. Login as root with empty password. At this point you need an Ethernet connection to the Internet to proceed, IMHO, without a lot of hassle getting wifi to work.

Do apt update, then apt upgrade, then reboot. Don't worry about the mouse going to sleep on you.

Now run tasksel, install Debian Desktop Environment, print server, SSH server, and I recommend XFCE desktop just because it's lighter on resources.

After all that installs, reboot, then login as root with no password. Now you have a desktop.

At that point, if you are security aware, run passwd root and change the root password. Then you can run adduser <your name> and add yourself as a user. If you need wifi, now is a good time to set it up.

I don't recommend Bullseye right now, as things are still missing and you will be running code still in Testing for the upcoming Bullseye release.

Also, you can sign up for debian-arm@lists.debian.org at the debian.org web site and follow the volunteer efforts to get real Debian running on the various arm hardware.

Good luck and have fun.

John W4JKL

Re: PSK-31 on Pi-zero

I totally agree Fred,  I will be using my Pi3B, running Ham_pi and connected to my Xiegu G90 TRX. With some luck the XYL will be starting RV trips and this will now be my take it with me setup. I will be running the G90 on a 12 volt external battery pack and the Pi on one of a couple 20,000 maH battery that is normally used to recharge phones. I am hoping for many hours with this type of battery and since they are fairly cheap having 2 or 3 is not a issue. 

Pi4 one day and most likely some sort of desktop application.

Running on the desktop where power is abundant, an RPi4 seems logical.

But, for portable use, maybe a less hungry RPi is a better choice.
