Tamitha Skov
If you are here for the first time, my name is Tamitha Skov. You may recognize me from TV shows I've done for The History Channel and The Weather Channel. I've been featured in Popular Science Magazine. I even do regular Space Weather broadcasts on TWiT TV. I want to open your world to a new kind of weather that's going to become very important to your daily life sooner than you think. Sound hard to believe? Think of all the technology we take for granted, like GPS and traffic apps on mobile phones, robotic drones and UAVs that have begun flying above our heads, high-altitude airline flights, satellite internet, satellite phones, Direct TV, even Sirius Radio -- all of these things are affected by Space Weather. As we become more reliant on smart, wireless technologies, our dependence upon Space Weather grows. Even today, emergency radio communications used by disaster relief agencies like the Red Cross depend upon what Space Weather is doing. Imagine, with no power and no cell phones, not being able to get through to your loved ones when its most important. Yet despite our growing reliance on Space Weather, very few people are even aware of it. I want to change all that. Im working to make credible Space Weather forecasts as common as the weather forecasts you see on the evening news. I would love for you to join me on this journey!

Medical Emergency
Dr. Albert A. Greenfield, an obstetrician, was about to retire for the night. He sat in his pajamas in a small room off his bedroom in Potomac, flipping through medical journal on pediatric and adolescent gynecology.

Two blocks away, his friend, Richard W. Hayman, was tuning the dials of his ham radio. He had just been talking to someone in Japan because he is planning a trip there in May.

K5ND
In the early 1960s my Dad purchased an antique, roughly 1940s era, Philco console radio. It had a shortwave band and a pretty good built-in loop antenna. I discovered HCJB in Quito Ecuador and was hooked on the magic of radio.

Morse code, however, with the records of the time, completely eluded me. The theory was fine but I just could not get the code. I did continue with shortwave listening and really enjoyed collecting QSL cards from around the world.

After my U.S. Air Force stint, I ended up in Merriman Nebraska where a kind ham helped me with the code and gave me the exam for the Conditional Class License, since we were well over 125 miles from an FCC examination location. My first call sign was WBØJXY in 1973. My activities were a few CW contacts, building some gear, and experimenting with 2 meter quad antennas.

On moving to Michigan and working for Heathkit, I traveled to the Chicago FCC office and took the exam for Advanced Class. With that, my new call sign was KB8CE in 1978. At that time my activities were RTTY with teletype machines.

After a long hiatus, I passed the Extra Class exam in 2006 and managed to snag the call sign K5ND. My early activity was running QRP CW and then entering a few contests mostly to chase DX. That transitioned to an entirely new approach to RTTY and contesting. Right now I’m focused on VHF-UHF contesting as a rover as well as satellite operations.

Thoughts on virtualizing Ham license exams?
I'm curious what people think. Should there be an option/method available, either in times like Covid-19, or any other time, during which we should be giving hopeful amateur radio operators the option of testing online? I believe that the Anchorage Amateur Radio Club VEC (https://kl7aa.org/vec/) is doing it.

With all that is happening in this world, COVID-19 has been getting the majority of the news and headlines. Nevertheless, Mother Nature is still at work and we do have a Hurricane Season that is soon approaching.

This morning, Dr. Philip Klotzbach released his first forecast for the 2020 Atlantic Basin Hurricane Season. “We anticipate that the 2020 Atlantic basin hurricane season will have above-normal activity. Current warm neutral ENSO conditions appear likely to transition to cool neutral ENSO or potentially even weak La Niña conditions by this summer/fall. Sea surface temperatures averaged across the tropical Atlantic are somewhat above normal. Our Atlantic Multi-decadal Oscillation index is below its long-term average; however, most of the tropical Atlantic is warmer than normal. We anticipate an above-average probability for major hurricanes making landfall along the continental United States coastline and in the Caribbean. As is the case with all hurricane seasons, coastal residents are reminded that it only takes one hurricane making landfall to make it an active season for them. They should prepare the same for every season, regardless of how much activity is predicted.”

Green Hero Engineering
Green Heron Engineering, LLC is dedicated to bringing amateur radio operators the best in sensible automation products, while providing the best customer support experience in our industry. Although we do have some commercial application, we treat everyone the same. Hams do not take a back-seat with Green Heron.

We are dedicated to providing solutions to common issues facing the radio amateur in integrating amateur equipment from any vendor. The RT-20 was introduced in May of 2005 and was an instant success as the first of a kind, totally unique product that solves real world station problems. The current version, the RT-21 v4, has evolved based on customer feedback, as well as our own innovations. It has features that contesters will love, remote station owners will wonder how they did without, and even the casual operator, with one rotator, will want to own and operate. The latest unit has an optional Wi-Fi embedded web server. It’s was rather obvious to us, that rotator manufacturers were ignoring the user view (the controller) of their products. We developed an easy to use, fully programmable, and good looking controller that works with any manufacturer’s rotator. We made it easy to integrate the software side by making our unit compatible with the Hy-Gain DCU-1 protocol with enhancements to provide many more modern features.

Over the years, we’ve added the Deluxe RT-21, a DC powered unit aimed at mobile or solar powered applications, and a universal Az/El controller that can’t be matched for versatility, performance and looks! We control everything from simple entry level rotators, to complete rotating tower multi HP motor systems.

Our “Green Heron Everyware” is a complete product family of modules, software, and devices that solve another set of problems facing us in our own station integration efforts, targeted to the absolute best in Remote Station control and automation. We needed to share station resources, eliminate the myriad of cables and many different antenna switch control boxes cluttering the operating positions and provide wireless “last mile” connection to switches while adding internet or local control with zero change in operating interface. We use standard IP protocols and human readable XML configuration files. There is no proprietary LAN or “secret sauce” mixed in. We are constantly discovering new and useful applications and are now can supply many of our own switching devices with built-in GH Wireless Control.

Our primary focus though, is not on our products.  We believe that if you buy from us, you deserve to get our full support as well.  This means that you can call or e-mail, that you will get a person or a response as soon as possible.  This doesn’t mean “within 2-3 business days”!

We continue to design, test and manufacture in the USA.

WN3R Remote Station
WN3R

I started trying to remote my Frederick HF station back in 2006. I was way ahead of the technology. Just a few years ago, I was finally successful in duplicating my local operating style remotely from Rockville.

The "Frederick" remote station consists of the following: Elecraft K3, KAT500 - ATU, and KPA500 Amplifier, RemoteRig, PC + TEAMVIEWER, and Green Heron Everywhere system.
The "Rockville" remote operating position consists of the following: Elecraft K3/0, Laptop, second monitor, CW paddle, headset, RemoteRig, and TEAMVIEWER - Remote Desktop software.

Antennas: 160M inverted "L", 80M sloping dipole fed with Ladder Line (Multiband), 40M dipole, Tribander, 6M beam, and 40M 4-square.

73, Dick, WN3R

Power failures
My first back up is a 5000 watt Engine Alternator Set (Generator to most folks).

Second back up is a Honda EU2000i Inverter Generator, over 400 feet of various outdoor cords, with weather proof connection covers.

Third is a "Pup" generator. That is a small engine mounted on a steel plate and fitted with an A pattern industrial belt pulley. That drives a high capacity vehicle alternator, using a A belt to another A pattern industrial pulley, which produces an effectively unlimited supply of 12 volt DC; i.e. more than I'll ever need. That will be supplemented with a large capacity sign wave inverter, once the stay at home order is lifted and I can prowl the wrecking yards for one out of a total loss service van or truck. I already have a source for a riding mower engine which is higher horsepower than the present one in case the one I have will not carry the inverter I hope to get. I plan to put together cord sets with the National Electrical Manufacturers Association (NEMA) standard connectors for 12 volt DC, to run to a Schlocky Diode battery isolator and a charge controller for the battery.

Fourth is the 2 Absorbed Glass Mat Valve Regulated Lead Acid 100 Ampere Hour batteries. Those are under continuous charge by the station's 50 Ampere linear power supply.

Solar Charging an HT?
I’d like to find an opinion for powering my HT via solar. The radio I’d like to charge with solar  is a Kenwood TH-D74a. I’m looking for a solar system for power  that is super easy and under 70$ if possible. Thanks!

Crisis 2020: how is it affecting ham radio?
I'm curious what people are seeing on-air during this shelter-in-place period. Is there an increase in HF traffic? VHF/UHF? Repeaters? Nets? Also, are we spending more time talking about the virus than about anything else? Or, is everyone just sitting around making puzzles????

Repeaters: sufficient backup power?
I'm wondering how much backup power is available to most VHF/UHF repeaters around the country and around the world. I'm also curious to know how many repeaters have battery only /vs\ solar+battery /vs\ generator?

Is it one-hour – to avoid losing the repeater during a quick power drop or failure – or is it several days in the case of a major power outage like after a storm or during a pandemic when, potentially, workers might not show up to a power plant to fix an outage?

Covid-19 (2020) and hamfests...
I'm starting to hear rumors about certain hamfests and the Covid-19 (aka coronavirus). Some hamfests are considering closing. Not sure what my feelings are with this. As with all public health emergencies, caution is critical. But we never shut anything down for the flu and yet every year thousands, tens of thousands in the US and Canada, die.

Thoughts? Anyone considering 'not' going to a hamfest in coming weeks/months because of Covid-19? Anyone avoiding Hamvention? (Full disclosure: Ham Communication currently has booths reserved at Winterfest in Annandale, the Masassas hamfest, and we're in booth 6206 at Hamvention!).

Virginia QSO Party 2020
I'm wondering who is going to take part in the Virginia QSO Party... My little gang is, that's for sure. Last year was a blast, and the weather was perfect. Here's hoping the weather is good this year. This said, the band conditions on 20m and 40m, as I recall, were as bad as could be.

Anyone?

HamCation 2020... done
HamCation 2020 was our first large hamfest. We are told that we did well; what's sure is that we're happy. We met some amazing people and signed up plenty of new members. We also entered into some really exciting partnerships that you will be hearing about soon. And yes, we will be back at HamCation next year, hopefully in the exact same spot.

You need to look at your available bandwidth for connecting to the digital network of your choice. DMR does require about double the throughput bandwidth of D-STAR due to the inherent coding (DMR is a ~9600 baud throughput while D-STAR is about 4800 baud). Fusion is dependent on the mode you are using and can vary. Fusion has become popular because Yaesu seeded the market with low cost repeaters and many clubs jumped on the bandwagon hoping to replace agin repeaters at a bargain price. The initial entry into the Fusion environment had its startup problems and now after a few years of operation, the Fusion product/protocols are well established  and the networking issues have been worked out.

With the advent of the newer hotspots which support multiple modes, the choice of what type radio is pretty much up to you and who you wish to QSO with. Many of the newer hotspots allow you to utilize a feature called "cross-mode" where your radio can be DMR and you can "cross-mode" to Fusion or NXDN. The newest hotspots can actually "cross-mode" to any and all of the modes from any other mode! This feature (software magic) has made the choice of which mode (and by association- the choice of radio) a moot point. Obviously, each OP will have personal brand choices for many reasons, but you are now able to join any network with almost any radio.

Anyone else studying for the Extra Class exam?
I studied hard last fall but wasn’t passing my practice exams by the week of the exam so didn’t go.  Then the holidays came around.  Now, I’m wanting to get back into studying and hoping I didn’t forget what I had learn so I can take the exam in March.

 I have no background in electronics so this is a challenge for me, for sure.  I’m using an extra class app on my phone, the arrl extra class book, and the study book by Gordon West.

Anyone else out there hoping to upgrade this year?  And any words of advice?

Thank you Frostfest
Frostfest 2020 has come and gone. RATS did a great job, thank you to the whole team. Early on, the line went as far as the eye could see and, from all appearances, lots of money changed hands. One of the highlights of Frostfest was when one of the announcers came on and told us that someone had lost over $500 in cash. The great news is that somebody else – an honest soul – found that money and brought it to the front office.

As for Ham Community, we were very pleased to make some fantastic contacts with over 60 new members registering on site. Our new band plan was also very well received. We, of course, look forward to comments and corrections so that we can make this the most useful band plans possible.

Next it's on to Orlando for HamCation 2020. We hope you will all join us there; we will be in Booth 099.
