Hello Operators
Continuing on with our Raspberry Pi field computer series, in todays video we're setting up raspberry pi gps time sync, for off grid raspberry pi projects or off grid commuications using a raspberry pi. For my project, my softare running on the raspberry pi, requires and accurate clock. Normally that would come from and NTP server when connected t the internet. When we don't have the internet, we need to find some other way to sync the raspberry pi clock, so that our communications applications JS8Call, WSPR and FT8, no when to start and when to stop.

I'll be running a Raspberry Pi 3B+ running Raspberry Pi Stretch, using a cheap USB GPS Dongle from Amazon. Although this tutorial can be used for many different applications. Mine is off grid communications eg ham radio with a rspberry pi.

Normally the time the comes from an ntp server on the internet. When I'm in a remote location operating from the field station, often there are no internet connections available. Naturally GPS coverage is available, so we can update the system click or the real-time clock if you have one.

I found a tutorial from Mike Richards entitled "Raspberry Pi Stretch – GPS Dongle as a time source with Chrony & Timedatectl" https://photobyte.org/raspberry-pi-stretch-gps-dongle-as-a-time-source-with-chrony-timedatectl/
You can find the complete instructions on Mikes website.

Enjoy the world of IOT the Internet of things.

Hello Operators
Extreme weather and grid down disasters seem to be happening more often, and with greater intensity. More often than not, when we organize off grid emergency communications training with our portable radio go kits, it usually takes place in fair weather conditions. What about training for a winter snow storms, the aftermath of a hurricane or tornado, ..? Training in fair weather is an easy way to become overconfident about our actual level of communications preparedness.

Enter the Winter Field Day Association.
Each year the Winter Field Day Association puts on a Ham Radio event called "Winter Field Day". The event is designed to motivate amateur radio operators to get out in the field, in conditions which are less than ideal.

This video is my take on how we can use Winter Field day, to develop or enhance our communications skills, in conditions most operators shy away from.

Hello Operators

For those of you interested in the conceptual design of the Solar Generator, please keep reading.

Stable 12 volt power is critical in tge home station and for the field radio operator. at home we usually use grid power, to power our stations while in the field, we use small lightweight battery packs to power our HF Radios for a few hours at a time, during casual portable communications. When we are faced with an Grid Down emergency or blackout, emergency power for becomes much more complicated. Not only do we need to ration the power we have, we also need to come up with ways of recharging our battery storage, if it is depleted. My concept is for a man/woman portable, 576 watt hour 12 volt , to power our stations, lighting and other devices, for a maximum of 24 hours before ever plugging in a solar panel.

The concept of a DIY Solar Generator is presented as an alternative to commecial solar generators, which rarely meet the needs of the ham radio radio operator, at home, or in the field.

For an Emergency Communications perspective, this diy solar generator becomes a module for a EMCOMM ARES, RACES, RAYNET go box being deployed in the field.

Hello Operators
in the first video with the DRAWS HAT for the Raspberry Pi, I speculated about the impact this new hardware would have on the ham radio digital mode community. Well now I have the DRAWS hat in my hands, so we can take a close-up look at what's in the package, and what the hardware is all about.

I'm running a hybrid station. That is to say, I use an Android tablet to interact with a headless Raspberry Pi. My Raspberry Pi is running JS8Call, FLDigi, WinLink, and WSJT-X. my Raspberry Pi Hardware is the 3B+

NW Digital Radio calls it a Digital Radio Amateur WorkStation. I can't tell you how stoked I am to finally have this product in my hands. In short, the DRAWS HAT makes integrating the Raspberry Pi with a HF radio easier and less expensive than ever before. Fewer cables, no audio interfaces, no cable mess, and a clean installation.

Why we should care about DRAWS
To be honest with you, when I first ran into this device, I thought to myself, wow someone has been watching my videos, solving the problem of integrating the Raspberry Pi, with all the components we need for digital communications. DRAWS is a Raspberry Pi HAT. This is a purely hardware solution combining several components for digital amateur radio, into a single integrated solution.

Video url: https://youtu.be/8jzHA_cjuwM

Main features
Pre-built Raspberry Pi Image This makes its easier to get started. Don't worry, DRAWS will also work with your own images after downloading a few libraries.

Built in high-performance audio codec. This means no more external audio interface.

GPS with pulse per second (PPS). Syncing time for Off grid communications is easy and accurate. Plus we free up a USB port as we no longer need the USB GPS dongle.

Embedded battery backed real-time clock (RTC). If the GPS fails, the RTC will still keep the time, no internet required.

12VDC native to power the DRAWS Hat and the Raspberry Pi. Now we get rid of inline buck converters and usb adapters to power the RPi. Everything gets powered through the same 12v supply as your rig.

Dual Rig interface audio sockets This isn't well documented yet, but from the images, we can see two radio ports for audio on the data ports of our rigs.

SMA connector for optional GPS LNA antenna. Now we don't have to rely on the internal antenna. If required, we can add an external antenna on the GPS for improved performance during sat acquisition.

I think this DRAWS Hat for Raspberry Pi is an epic change in portable digital ham radio, and how we integrate digital communications into our rigs. While companies are adding PSK31 to qrp rigs without thinking about how we as field operators will use that "feature", companies like NW Digital Radio are helping push digital ham radio forward, by essentially giving us a single wire integrated solution, for digi mode integration.

Somebody is finally paying attention to the new breed of portable ham radio operators using the Raspberry Pi for digital ham radio in the ham shack, off-grid, and in the field.

Hello Operators
Portable power is always a popular topic on the channel. So today we are building a 12v, 4S4P, Lithium LiFePO4 battery pack using 18650 cells and the Vruzend battery kit.

The DIY 18650 battery pack is very popular. We can choose lithium Ion, or Lithium Iron phosphate 18650 cells for our build. Most 18650 project use li-ion cells, but we will be using LiFePO4 cells for this build.. Repurposed or purchased new, these lithium and lithium iron phosphate cells are a popular choice for diy power banks, solar generators, or other battery projects. One of the biggest problems with diy building 18650, battery packs is damage caused by overheating cells with a soldering iron. An often overlooked fact of 18650 building, is they were designed to be spotwelded, not soldered. The Vruzend kit solves this problem by using polymer end caps on the 18650 cells. These end caps are removeable, replacable, and allow the builder to make custom packs in varous shapes and sizes.

This diy battery build uses LiFePO4 cells in 18650 format. if you would like to use Lithium ion cells, you might want to use a 3S4P configuration, to achieve a roughly similar 12v battery result. Lithiun Iron Phosphate cells are much safer than Lithium ion cells. For the maker wishing to build a 12v battery pack, the LiFePO4 cells offer a nearlly one to one replacement over lead acid batteries.
You can consider this build a kind of DIY Powerwall for your pocket.

Hello Operators
Recently Chameleon Antenna released an updste to the popular portable ham radio antenna, the Chameleon MPAS ( Hybrid Micro, MIL Whip, MIL EXT, CHA Spike ), seen regulary on the channel. This new system is call the Chameleon MPAS 2.0. The man portable broadband ham radio antenna is a rapid deployment specialist. Rugged construction, all weather deployment, and designed to take horrific conditions in the field. Since the original Chameleon MPAS has been a large part of the portable ham radio ops on the channel, I thought it would be a good idea to present the evolution of this modular portable antenna system, and its components. Introducing the Chameleon MPAS 2.0

These components can work independently, or as a system. They can also integrate with other antenna elements from various manufacturers using the 3/8 24 male/ female mounting system.

The primary goal of this portable HF antenna is a rapid deployment, with a multitude of configuration options. This allows it to , meet the real world requirements of the operator and conditions. The system can be used as a vertical whip, or deployed in most wire antenna configurations.

List of products seen in this video:

Waiting for the new Yaesu FT-818 qrp portable ham radio? Watch this before you by.

Hello Operators
In todays video we review the Yaesu FT-818, in comparison to the Yaesu FT-817 and FT-817nd which came before it. The video goes through the top 5 reasons I believe the Yaesu FT-818, all mode, all band HF VHF UHF radio is a complete fail, as a replacement to the Yaesu FT-817 series. It's not a slam job. The intent is to open an honest discussion about the community expectations for the Yaesu FT-818, and the Yaesu Field radio strategy going forward.

A portable solar generator built inside an ammo can which you can build at home to power your off grid ham radio station.

Hello Everyone.
In this video tutorial, we'll be building an off grid portable solar generator DIY. We will be using it for the ham radio station, for emergency power, and for our solar powered off grid adventures. The batteries are based on Lithium LiFePO4 (lithium iron phosphate) cells for a 3000+ cycle, cycle life, compared to 500 cycles for AGM batteries. This gives us a long lasting an lightweight portable battery for field communications and preparedness.

This build includes solar battery storage, Bluetooth shunt, fuse block with LED blown fuse indicator, Anderson Powerpole pods, ground bus, Bestech BMS, Genasun MPPT charge controller, ammo can enclosure, ...

We'll use this LiFePO4 solar with PowerFilm Solar panels, as an off grid or grid down emergency portable power system. At home we power the system with 2x 40 watt Renogy panels. In the field the system is powered by one 120W PowerFilm and/or 2x 28 watt rollable panels.

This 12 volt lithium generator project is an excellent way to learn self reliance for a blackout, shtf or basic grid down preparedness. Once built and put in to use, this dolar generator produces 100% free energy for emergency power, grid-down communications, amateur radio, boon docking, van or RV life, or to keep food or medicine refrigerated during grid down emergencies. Main features - 576 watt hours, 45amp hours - 2000 charge cycles - 30A ports - 2x USB ports - Internal Bluetooth battery monitor - 4x DC Powerpole ports - Every port is individually fused - MPPT charge controller - Dual Solar inputs - Total weight 18lbs (8.3kg) - Easy maintenance - Replaceable Components - Optional pure sinewave inverter - Easy to build The closest commercial product is the Goal Zero Yeti 400 Lithium. Our diy solar power generator will outperform the Yeti Lithium, (unless you need an inverter), the Yeti has one built in, but an onverter is optional in the DIY Solar Generator . Most people don't need AC power or the inverter with a solar generator. They just need tthe right connectors for their gear. An interesting feature on the solar generator is the wireless battery monitor from Thornwave labs. The battery monitor is a Bluetooth enabled shunt using Bluetooth SE to send information about the state of the system straight to our mobile phone. it's also got an API to get data out to something like a raspberry pi or arduino for data logging.

Episode and build notes.

Hello Operators
Back in February 2019, I published the DIY Solor Generator video. That was a 576 watt hour 12 volt LiFePO4 portable power and solar storage system for ham radio emergency communications and preparedness. In this video I follow up on that build, answering questions about the first build, and sharing modifications made, making this system easier to build, easier to maintain, and the best diy portable power project in teh ham radio community.
Here is the original video link: https://youtu.be/Nf9X4YIK9xA
Share the update video: https://youtu.be/yJawygsz91s

For ham radio operators, this update is just in time for ARRL Field Day 2019. With the latest updates to the system, a two operator station, with two individual rigs, augmented by solar power, can run the entire field day weekend, with a single system. This build includes solar battery storage, Bluetooth shunt, fuse block with LED blown fuse indicator, Anderson Powerpole pods, ground bus, Bestech BMS, Genasun MPPT charge controller, plastic can enclosure, ...

I'll use this LiFePO4 solar storage system along with PowerFilm Solar panels. For field day 2019, I'll keep the system topped up with 2x 28 watt R28 panels from PowerFilm Solar. If Field Day 2019 is covered by grey skies, I'll also deploy the 120W PowerFilm, in a two charge controller configuration as shown in the video.

PowerFilm Solar was kind enough to offer our community a discount code for their products on Amazon. The code is valid through ~June 2020. Feel free to use the code OH8STN10 and this link ( https://amzn.to/2In4Cxx ) to PF panels on Amazon. It supports the channel, and also shows PF that the community, appreciates PowerFilm Solar.

Hello operators.
In this video we look at the three different portable solar panel models from from PowerFilm Solar, Thess are the solar panels I use for ham radio and portable power in the field. The FM16-7200 120 watt and the FM16-1200 20 watt folding solar panela/s, and the R21 and R28 20 and 28 watts panels, from the PowerFilm Solar rollable solar panel series.

It's not always easy to understand the difference in specs and features between the different series, so this portable solar panel comparison will help you decide on the best panel for your unique applications.

Near Vertical Incedence Skywave or NVIS is a antenna configuration used for reliable local to regional HF communications on 160, 80, 60, & 40 meters. NVIS has a greater range than VHF communications or communications through repeaters, but achieves effective HF radio vomms with little or no infrastructure.

Hello Operators.
In this video we demonstrate NVIS regional communications with JS8Call. We do this to achieve reliable radio connections on 40 and 80 meters. JS8Call has a variety of messaging functionalities built in. Message store and forward, message relays, ... all disgned to work stand-alone, or through the JS8Call MESH network. JS8 is a narrow bandwidth weak signal mode, working extremely well for NVIS ( Near Vertical Incidence Skywave ), and an asset to emergency communications and preparedness. In this video, three stations all within range of one another, demonstrate the Messaging capabilities of JS8Call, on 80 meters amateur radio band, using NVIS. This could easily be an amateur radio emergency data network, albeit on 80m HF. My NVIS antenna was set up horizontally, three meters or 11 feet above the ground. it is a 133 foot or 40 meter end fed random wire antenna. For this test, no counterpoise or reflector was used. NVIS works well on both 40 meters and 80 meters. In upcoming videos, we'll demonstrate other combinations of JS8CALL and NVIS on both bands.
