Portable Ops in Comfort

Towable Shack

Working my rolling shack portable station from air-con comfort


We've had a few RV's over the years, but for some reason I've never thought to operate from inside the RV.  I have always tossed a wire over a tree and operated from a picnic table or from my camp chair, as here...




But I thought, "Hey, I have a 12v power supply built-into the RV and the built-in ladder makes a nice solid mount for an antenna mast."

Early try with a military fiberglass pole mast

Now I use a Flagpole Buddy with a 30 foot telescoping mast


Here's a link to the flagpole buddy... link

Our RV has a Converter / Inverter with a spare 25 amp 12v circuit.  I tapped into that and ran a power pole wire to the dinette table.  

The camper had a coax outlet to watch a TV outside the camper... that's obnoxious.  So I cut the cable TV coax and crimped on a UHF connector, and ran that to the dinette table.  I simply attach my coax from outside the camper to cable TV coax adapter to get the antenna connection inside the camper.  Wallah, coax through the wall with no drilling. The cable TV coax run from the dinette to the wall outlet is only a couple feet so it's not really impacting the impedance of the coax run to the antenna.

I've tried a couple of antenna's and have settled on my end-fed 44 foot wire fed with a 9:1 balun and some clip on radials.   I pull the antenna wire through top end of the telescoping mast with kite string, counter-weighted with a heavy sinker.  That keeps the wire taught from the end-fed point up to the top of the mast and out at an angle.

Gone RF fishing with a 30 foot pole and a big sinker.


The Elecraft KX3 and Ten-Tec Eagle will both match a bent spoon with their auto-tuners and have no trouble with the end-fed on 40m and above. 

For a portable key I use my Palm Radio Single paddle.  Either magnetically attached to the steel side of the Eagle or just held with one hand while operating with the KX3.

On the Eagle the Palm Radio Single magnetically attaches to the side

One thing I find interesting about operating while "camping" (if you call towing a small house to a campground camping) is that I seem to also work a suprising number of other stations that are operating from a campground.

Note the power and antenna connections under the table


The KX3 can stay on the dinette and doesn't take much room.  Keeping the footprint small and the earbuds in, keeps the XYL happy when operating during an outing.

I worked a number of stations on 40m, 30m, 20m and 10m this weekend.  It's always fun to tell a station that you are portable, even if you are essentially operating in your home away from home.


Thats all for now.

Lower your power and raise your expectations

  • Carrot Cake Cheesecake Bars

  • Description

  • In this life, I have 3 desserts that rock my world.  #1 is carrot cake, #2 is Cheesecake… and #3 is Key Lime pie.  This dessert, which is perfect for your Easter meal, scratches my top 2 favorite desserts off that list in one tasty little dessert!

  • Ingredients

  • 1 cup and 2 tbsp. flour

  • 2 cups sugar, divided

  • 1 1/2 tsp. Ground Cinnamon

  • 1 tsp. baking soda

  • 1/2 tsp. Ground Nutmeg

  • 1/4 tsp. salt

  • 2/3 cup vegetable oil

  • 4 eggs (divided)

  • 2 tsp. Pure Vanilla Extract

  • 1 1/2 cups finely grated carrots

  • 3 (8 oz.) pkgs. cream cheese, softened

  • 1/4 cup milk

  • 1 tsp. Pure Lemon Extract

  • Directions

  • Preheat oven to 325°F. Mix 1 cup each of the flour and sugar, cinnamon, baking soda, nutmeg and salt in large bowl. Add oil, 2 of the eggs, vanilla extract and carrots; mix well. Spread 1/2 of the batter into greased and floured 13x9-inch baking pan. Reserve remaining batter. Set aside. Beat cream cheese and remaining 1 cup sugar in another large bowl with electric mixer on medium speed until well blended. Add milk, remaining 2 tablespoons flour and lemon extract; beat until well blended. Add remaining 2 eggs, 1 at a time, beating on low speed after each addition just until blended.

  • Cadbury Creme Egg Shots

  • Description

  • Continuing on with the Easter theme… how about turning a Cadbury Creme Egg into a Shot Glass?  Russ loves the Cadbury Creme Eggs (I’m not a fan), but I might change my mind using this recipe!

  • Ingredients

  • 6 large Cadbury eggs (NOT the Caramel ones!)

  • 2oz Irish cream

  • 2oz White Creme de cacao (dark will work in a pinch)

  • 2oz Heavy Cream (milk will work in a pinch)

  • Directions

  • Unwrap the Cadbury eggs at least halfway (or take the foil wrapping completely off) and place on a cutting board. Boil some water and stick the blade of a serrated knife into the water, giving the blade time to get very hot.  Dry the blade off quickly and use it to cut the top off the Cadbury Egg (you’ll want to cut just a little over 1/3 of the top of the egg off, leaving enough room to scoop out the contents).  Be careful when using a “sawing motion” to cut off the top of the egg, or the egg may crack, rendering it unusable. Scoop out the creamy center of each egg and place in a small bowl.  Pour the Irish cream, White Creme de Cacao and Heavy Cream into a cocktail shaker.  Add the creamy center mixture from the Cadbury eggs into the shaker. Secure with a lid and shake, shake, shake! Pour into the hollowed out chocolate eggs and ENJOY! Strawberry or Caramel Irish Cream bumps this up to the next level of yum!

  • Russ’s Drink Corner

  • Kirk and Sweeney Gran Reserva Rum

  • Description

  • Handcrafted in the Dominican Republic, this rum adheres to the very strict regulations to be called “Dominican Rum”. The process begins with hand harvested, high quality sugarcane that is pure. The byproduct of the sugarcane, “Blackstrap Molasses” is then carefully fermented and distilled. The rum is then aged in a variety of American and French oak barrels, with the distiller conducting various steps of dumping, blending and re-barreling through the years. The final blend is a selection of variously aged rums between 5 and 20 years, painstakingly hand selected, this is indeed a rum well worth pursuing. It delivers an intriguing range of aromas, from intense vanillas to faint notes of sherry and raisins–all built upon a notable undercurrent of roasted cane sugars.

  • Mashbill: 100% Sugar

  • Proof: 80 (40% ABV)

  • Region: Dominican Republic

  • Nose: This full-bodied rum delivers an intriguing range of aromas, from intense vanillas to faint notes of sherry and raisins–all built upon a notable undercurrent of roasted cane sugars.

Bacon and Eggs…not radio but very interesting.


 

 My dad passed while I was at a very young age but through my mom, I learned that he was a Lancaster bomber pilot in England during WW2. I remember asking her questions but she did not know much as he spoke of his time in the war very little. 

What I did know was he was a commercial pilot in Ireland and then joined the Air Force during the war. At the time he was asked to train as a tail gunner as at the time there were too many pilots and not enough Lancaster aircraft. He completed his training but never sat in the tail gunner turret as he was called up as a pilot. That's all I know of his military time but I have always had an interest in that part of his life. When I lived in Ontario just outside Toronto is the home of the Canadian Warplane Heritage Museum. They have one of the very few flying Lancaster bomber aircraft. In the book the sound of the Rolls-Royce Merlin engines of the Lancaster were often mentioned. I can somewhat understand this, when the museums Lancaster was out flying as it did often you could hear the rich sound of the 4 engines.


This brings me to the book I just finished reading called Bacon and Eggs the story of a Lancaster bomber crew. It is a fictional story based on real crew and actual events. This book goes over the events of the formation, training and missions of one Lancaster crew. It's a short read and is available on Amazon as a book and ebook. If you subscribe to Kindle Unlimited then it is a free read. In closing, after reading the book I look at sitting down to a meal of bacon and eggs in a different light now.
