Re: Looking for Wire Antenna Suggestions

I have used a heavy duty spring attached to the tree with an eye bolt. The spring I used was from the hood of a car. Got it at a salvage yard not sure if cars have hood springs any more. If not a trip to the hardware store to find one but be sure you get a good heavy one as you will find a great deal of tension on the supporting rope. I used parachute cord which I bought at a surplus store it stood up well to the UV and the cold winters I had in Nebraska.

At the 10 feet point the tree is thick enough it does not sway in the wind.

I would like to raise the far end of the antenna but of course the higher you go in the pine tree the more it sways when the wind blows. The wind blows often here in central Illinois!

Looking for low maintenance suggestions for adding a shock absorber of some sort in the rope that supports the far and. It isn't too practical to run the rope through a pulley and provide a weight to keep it taught but that isn't 100% out either. Has anyone had success adding a spring system, heavy duty bungee cord type absorber, or something else?

Happy New Year everyone!

Tie a couple of loops in the rope and stretch a bungie cord between them.  Works great on dock lines also.

Some rope will have some stretch to it. If you do it this way the rope should be at lest 100 feet long. It's what I do here. Mark/WQ8S

WOW
I had no idea something as simple as an audio amplifier has gelled into such complex
configurations.

found this on the web:


It is a common misconception that wireless hearing aids use Bluetooth. In fact, most so-called "wireless" hearing aids on the market today rely on a technology called near field magnetic induction, and use a Telecoil to receive a signal sent from an intermediary device (a neck loop transmitter), which is worn around the user's neck. A main limitation of this technology is that the transmitter must be within 3 feet of the hearing instrument. These hearing instruments do not contain Bluetooth technology. The Bluetooth connection only exists between the neck loop transmitter and the audio device (for example a television or other audio device) which translates the Bluetooth signal into a near field magnetic induction signal.

Recent technological breakthroughs in the miniaturization of radio frequency antennae have enabled hearing instruments to embed the radio antenna inside the hearing instrument. This approach provides a direct connection from the hearing aid to the wireless audio transmitter (typically connected to the television or other audio device), eliminating the need for the user to wear any intermediary device around their neck and allowing them to be up to 30 feet from the transmitter. These devices operate on 2.4 GHz.

2.4 GHz is a widely used and globally accepted frequency band and is used by most cordless phones, video game consoles, home wireless networks, garage door openers and many other common everyday wireless items. The 2.4 GHz platform can communicate directly, device to device. As mentioned, the induction/T-coil-based "wireless" hearing aids require the user to wear a neck loop to transmit the signal to the hearing aids. In addition, the Bluetooth communication between the audio device and neck loop transmitter introduces significant time delays, which can cause disturbing echo or lip-synch effects when watching television.

Another misconception is that hearing aids that operate on 2.4 GHz encounter interference because it is a commonly used wireless platform. Hearing aids using the 2.4 GHz wireless technology safeguard against interference in two ways. One is by transmitting exceptionally small data packets. With each data packet being only 0.00016 to 0.0005 seconds long, there is a high probability of uninterrupted transmission for that reason alone. A further safeguard is frequency hopping. This means that each time a new piece of data is to be sent, a new channel out of 35 possible channels is picked for the transmission. Because other devices in the 2.4 GHz band use different channel selection strategies, they virtually always steer clear of each other. This approach of "hopping" among channels has virtually eliminated the interference many used to experience with early cordless phones. This same approach to frequency hopping can now be found in hearing instruments and prevents annoying interference between wireless devices.

Re: Field Day 2019

Charles W. Powell
 

Here is an update on our Field Day plans.

  • We have four sites reserved at Weston Bend State Park in Weston MO, # 28, 29, 30, 31.  Two adjacent and two across the drive
  • The sites have power and RV pads.  We still plan to operate battery power, but mains power can be used for anything else EXCEPT a computer that is used for CAT control.  Logging functions are alright on mains so long as they are not connected to the radio.  (I plan to connect my computer for CAT control, so I will operate my laptop from batteries)
  • We will have CW and SSB, which means we will have at least two transmitters.  No one has suggested digital modes as yet, but we certainly could consider that.  At 5 watts or less, CW = 10 points per QSO, SSB = 5 points per QSO, and digital = 10 points per QSO.  We have yet to decide on the total number of transmitters and what bands to operate.  (Remember that for the purposes of FD ALL transmitters are 5 watts or less, including SSB)
  • As of now, we have seven who are planning to attend and four possible attendees.

Chas - NK8O

It is at the same time quieter and gives better signal reports than my other antennas mostly dipoles and a 40 m loop.
