I Don't Need 1.21 Gigawatts, a Flux Capacitor or Plutonium to make a QSO

-

 



Note: I've had this post in the can for a long, long time and felt now; due to the potential of price increases as a result of tariffs directed to countries where these batteries are produced, it might be a good time to look at these batteries.


I look back to 1985 when the "Back to the Future" movie was release when we became aware of the Flux Capacitor and I remember when operating portable those days of lugging around a BIG HEAVY battery to operate with my Ten Tec Omni transceiver. In the words of a Bob Dylan song, "The Times Are a'Changin"

No more lugging around a 16+ lb. 12 volt battery.  In today's Amateur Radio World, all I need is one of these units to power my Amateur Radio portable activities.

Thunderbolt Magnum 9V 200 mAh NiMH Rechargeable Battery



A few years ago I came upon a YouTube video review by Jason KM4ACK about his experience with this affordable priced LiPo4 battery he had purchased on Amazon.  I had just recently purchased a used Yaesu FT-891 and was in need of an average capacity battery.  Jason hit the ball out of the park with this review.

I ended up purchasing two of these 16 Ah LiPo4 batteries Over the these few years both of these batteries have served me well through many portable SSB, FT8, Winlink, Packet, CW, and satellite activities.

This is not an endorsement or non-endorsement of this battery. In May 2024. I brought out both of them to re-charge with my TP Solar 60 Watt Solar Panel. ( Another item I was introduced to by Jason KM4ACK)  Both had not been charge since July 2023.  To my amazement, one battery showed 13.6 volts and after being solar charged for about 15 minutes, it went into float mode.  The other battery showed 13.2 volts and took about 45 minutes before going into float mode, largely due to skies becoming overcast. I was amazed by how little voltage degradation of both batteries over a year period.

Since I am a car-free person, most of my POTA activations are via bicycle or when I don't feel like cycling, I'll walk or use public transportation to a POTA site. As a result, weight is always a consideration when it comes to my portable ham radio activities. 

The 12V/16 Ah battery fit my weight needs perfectly. In the picture below is one of the POTA setups I use with my FT891, Buddipole Power Mini, TPSolar panel and the Miady 12v 13Ah battery.

My other POWER BANK is what I call my Smoke Detector Power Systems.  The results of using this Thunderbolt Rechargeable 9V /200mAh battery is truly astonishing.


Yes, this 9 volt battery has powered my QRP Labs QCX Mini CW / Morse Code Transceivers with unimaginable results. 

During the 2024 total Solar Eclipse over a wide area of the U.S., I setup my 20 meter QCX mini in WSPR mode with this 9v battery and was shocked at the beacons that picked up my signal.  RBN receivers not only across the U.S. but Alaska and Australia as well.

Like so many of portable ham radio operators, there are times when Murphy rears its ugly head. Upon setting up for a POTA activation on 6/8/2023, I realized I forgot my Talentcell battery, Additionally, the YouKits HB-1B rig I was using was fully uncharged. Dismayed? You bet.  But I remembered I always carried the 9V 200mAh  battery for emergencies.





HF band conditions weren't great during this early late morning activation and I was shocked to say the least of the results I garnered during this short valid activation with less than 1 watt on 30 and 20 meters using Morse Code.





A year later this time I purposely operated with a 9V battery and the results were equally amazing and satisfying. 





Finally I learned about the Talentcell Battery banks from Mr. QRPer, Thomas K4SWL.  These small lightweight batteries are perfect for my "Ham on a Bike" Parks on the Air activations. 



I use the one on the left (12v-3Ah) mostly for operating with my QRP Labs QCX 40 / 20 meter mini, my YouKits HB-1B unit and QRP Labs QDX Digital rigs. 








For long duration digital operating I use the (12v-6 Ah) Talentcell for my QRP Labs QDX when operating FT4/FT8.



And of course, there is OLD RELIABLE 12v-3Ah Bioenno battery when using my FT817/z817 combo.



My take on these batteries is not only are they light in weight , extremely powerful and durable for my "Ham on a Bike" applications, but I don't need to carry around a batch of plutonium, a Flux Capacitor nor travel at 88 MPH in order to achieve 1.21 Gigawatts to make a QSO.

This QRPp Fishing Lure Helped Me Snatch A BIG ONE Working My Greyline

  Renowned Golfer Jack Nicklaus made this quote about fishing.  "There are always places to go fishing. For any fisherman there's always a new place, a new horizon".   I equate that quote to my portable Amateur Radio activities. There are always places to go operate Ham Radio.  There are always NEW Parks on the Air, Summits on the Air, Islands on the Air and other places to operate portable and another day or opportunity to make a QSO. During my daily Early Bird Parks on the Air activation on August 13, 2025, I decided to operate QRPp ( less than 1 Watt ) with my QRP Labs QCX 40 Meter Mini with a 9 Volt / 200 mAH battery.  Due to the excessive heat in the Ohio River Valley in Kentucky, U.S.;  I try to get out around dawn to "Beat the Heat" and recently take advantage of the morning greyline over my QTH. I don't operate QRPp often but I looked back at my previous QRPp operating and found I seem to do this when HF band conditions are questionable.  ...

The MOST IMPORTANT part of your Ham Station is NOT your RIG!

  Over the last few weeks all over the planet Mother Nature has been rearing her ugly head with rounds and rounds of different types of devastating effects of Terrestrial Weather.  For some of us in the Amateur Radio community Space Weather has not been a bed of Roses either. How does this play into my Amateur Radio operating?  It leads me to an ADAGE most of you may have read about in that the MOST IMPORTANT part of your Ham Radio Station is NOT your RIG. IT IS YOUR ANTENNA. I've spent the better part of this summer checking all of my antenna for wear and tear, repairing those that needed and putting each one through their paces on my Nano NVA. Due to unpredictable Terrestrial and Space Weather conditions, my HF operating and Parks on the Air operating have been somewhat diminished during the last few weeks. That has lead me to understand that in the waning period of Solar Cycle 25, I can likely expect the unexpected as we journey on the downside of this cycle.  As ...

There's One Line I Don't Mind Waiting In. "THE GRAY-LINE or GREY-LINE"

-
Image
  Drive Thru Lines, School pick-up Lines, Bank Lines, Grocery Store Lines, Airport Lines and the lists of lines can seem almost endless.  Recently I've come to enjoy standing and waiting in what's called  "THE GRAY-LINE" or "GREY-LINE". Since I'm in the U.S., I'll use the Gray-Line spelling. What is "THE GRAY-LINE"?  For those new to Ham Radio or have not move that far along in their journey of the hobby; it can be defined this way.  "THE GRAY-LINE" is a band around the Earth which separates daylight from darkness.  Propagation along the gray line is very efficient.  The main reason is the D layer of the ionosphere, which absorbs HF signals, disappears rapidly on the sunset side of the gray line and it has not yet built upon the sunrise side.  In the YouTube below Dave Casler explains.  I've worked "The Gray-Line" on many occasions over the years but not in the last few years.  Here it is August 2025 and August is ty...
