Re: NON HAM QUESTION 2.4gHz hearing aid
2.4 ghz is also a common frequency of the magnetrons in microwaves. 73 Jim Parks NY0J
From: main@4SQRP.groups.io <main@4SQRP.groups.io> On Behalf Of Rob via Groups.Io Sent: Saturday, December 29, 2018 9:32 AM To: main@4SQRP.groups.io Subject: Re: [4SQRP] NON HAM QUESTION 2.4gHz hearing aid 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.

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.
72, Chas - NK8O

Yes, I was happy. Now everything is scaled down to a 43 foot dipole wrapped around three sides of building. When weather warms up will
put up an off center fed with 4-1 balun. (My spell check selected balloon, baling and blain)
Building a 20mm QRP rig and placed a semiconductor backwards. Have tried the usual methods, solder sucker and wick to no avail. Any suggestions greatly appreciated.

It is at the same time quieter and gives better signal reports than my other antennas mostly dipoles and a 40 m loop.
I see (hear) hams who use and brag on air that everyone on 40 needs an amp or they don't belong. huh.
Sorry for deviating off topic Pretty hard to be portable except on the deck with a big loop.

Thanks for letting me know I am not alone! This is my first attempt at building a kit. When/if successful can take my place among those who have gone before.

I am going to bring in the new year with a deluxe hot air soldering station, the X-tronic #6040. This should aid my efforts to complete my wattmeter and Hilltopper construction. Wish me luck..
Happy new year!

You have lost the mismounted semiconductor. Cut the leads with a flush sidecutter or xacto blade as close to the semiconductor as possible and tip it up or remove it. That should allow you to remove the remaining leads from the thruholes with soldering iron & tweezers or push them out backwards.
Do not overheat and damage the PCB. Good luck.

There's a Youtube video on surface mount tech that details removing an IC with a process that should work on through hole as well. Check it out.
