This beautiful estate is available for rental.

This experiment consisted of using a Chameleon Hybrid Portable HF Antenna the counterpoise was placed in the Potomac River for the in water experiment and taken out of the out of the water experiment. ** update apparently I connected the counterpoise to the radiator of the antenna** I will have to redo this experiment again.  I made a quick internet search on water propagation experiments and found this document Radio-Wave Propagation Measurements over Sea Water

I haven’t used the record feature of the Icom 7100 too much but it wants to separate the transmit and receiver signals so hear is the unedited record

I worked a POTA station with two parks

 And I was able to get up with N4AED in Wendell and he had a nice strong signal on 40 meters

The equipment I use for portable operation includes the following:

  1. Icom 7100
  2. Chameleon Portable HF Antenna CHA HYBRID Micro
  3. Cha Spike Mount
  4. Bioenno Power 12V 20Ah 240 Watt-hours Lithium Iron Phosphate Battery
  5. Bioenno Power 28 Watt Foldable Solar Panel
  6. Bioenno Power 12V/24V 30A Solar Charge Controller
  7. MFJ Model MFJ-969 Deluxe Versa Tuner II antenna tuner
  8. 3 ring spiral notebook
  9. Ball point pen

am able to carry all the equipment in a backpack and a Apache case. I do have to carry the tuner in my other free hand.

One Amateur’s Solution to HOA’s Restrictions

Amateur Radio, Outreach, Portable

By Mark Gibson (N4MQU)

When I first moved to North Carolina I upgraded to my amateur radio general class license and spent time on the road.  I started out with a  Tarheel Antenna on my Chevrolet van. After I wore that car out I purchased a Ford Tempo. I don’t have a picture of the antenna on the van but do have a picture of the antenna on the Tempo.  For some reason we had my wives call on the Tempo.

Fast forward I removed my radio from the car and put it in storage. My friend Doug Williams (KS4TI) expressed interest in it and I unloaded the antenna on him.  I mean he purchased this fine antenna from me at a bargain price.

Fast forward Doug decided that a amateur radio operator should move into a development that had restrictions on what you could have on your own property.  I have known Doug to call this antenna a gaudy antenna. I guess at some point he took it off his vehicle and decided to use it on his homes restricted neighborhood. Here is a couple of images of his antenna.

I’ve known Doug for many years and he conducts the JARS Prep Net amateurs may check in and talk about topics related to keeping you safe and healthy during an emergency every Tuesday night at 9:00 PM on the AK4H repeater in Johnston County.

What activities can you do while you are camping?   There are the usual things you do, hiking, exploring, bird watching, singing around the campfire, playing board games, listening shortwave radio… ? Metal detecting…? Watching satellites..? Astronomy.? How about seeing how many other people you can talk to in other parks or states. That’s exactly what I did Labor Day weekend 2021. 

Tips on Using Non Automatic Lenses

Photography

equipment 

Cannon T5i body

Use auto for ISO. Why it seemed to work.  Trying to switch from the ISO did not work but when I switched to auto it worked. I learned from a retired professional photographer current with the new technology on cameras, using  the older lenses with the camera the camera will still be able detect the proper ISO. 

I will also be working on taking pictures of small cities at night.  This will make me use my limited photography skills to the max.

I am taking a look at the hobby of Short Wave Radio Listening (SWL) with fresh perspective and a new radio.  

Tecsun H-501x

So far I have enjoyed the features of the radio.  Rich stereo sound, direct digital entry of frequencies two tuning knobs one for regular tuning the other for fine tuning. I heard radio Cuba on 15140 kHz. I also heard I think was FT8 on 14075. I also heard someone preaching on several different frequencies along with non English stations throughout the bands. I will enjoy learning more about this radio.  Be careful where you order it from to make sure you get the rechargeable batteries and charger.  I ordered mine from https://www.anon-co.com/product/tecsun-h501x-radio for $298 plus about $20 shipping.  I ordered it Sunday night and received it Wednesday.  Be sure to check out the YouTube reviews.
