Did You Say Interference ? I Can't Hear You. Say Again

posted by Stones River

What is that hum? Not all interference is intentional, however there are many forms of intentional interference. This video below lets us know that this is nothing new at all. Just recently I installed 2 4' led lights that replaced the normal florescent tubes. The ballast was removed and wired direct to 120v ac. I like the instant light source and the cost efficiency, however it is a rf menace on the am band for sure. In the same room I have a am radio tuned on 650 am the famous WSM Radio in Nashville Tennessee. When I flip on the led lights the am radio signal is full of hash and could not be tolerated very long at all. Flip the led's off and the radio does 90% better. So after having bought some very good quality led lights for each room of my home I began to install. Keep in mind this was before I made the am radio discovery. I began putting up the lights, as I progressed I noticed new interference in my am radios. I flip light on and there it is again. Flip it off and noise level dropped at least 90%. So I got the packaging out and of course the small print plainly says.
" This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications."
That over the horizon hum, what is that? Could it be? There are unlimited sources of radio interference in today's world. Something as simple as loose connections on the ground wire of the electrical pole, via the staples on the pole.
Enjoy this wealth of information below.

This playlist is a Shout Out to Real Hams, the kind that Live & Let Live. The kind that Elmer new members and not Ostracize them. The ones that allow you to make mistakes and learn. The ones that don't try to control your every move in Ham Radio. A few of these videos in this list is really intended to alert the Narcissistic Radio Club members that we really just don't have much time for their BS. Every club has them.
You try to figure out whats what or who's who?

The Ultimate Fox Hunt by KI4NDN

Food For Thought
Safety Fox


On April 30, 2015 there was a balloon launch by fellow Ham KI4NHK. With very little info, I began to see if I could track or even locate the balloon launch on aprs. The info is @ https://sites.google.com/site/stonesriveramateurradioki4ndn/news/balloonlaunchthisweekendmtrasmiddletennesseeroboticsartssociety

The following year on April 23, 2016 KI4NHK launched another balloon. This time there was aprs beacon malfunction and the payload was lost.
https://sites.google.com/site/stonesriveramateurradioki4ndn/news/mtrasnearspaceamateurradioballooninfoapril92016Balloon Launch April 26 2016
Having done a pre-launch prediction, there was a general idea of where the payload would land. The previous year when I had run a pre-flight prediction, it missed 13 miles. This time around it missed approximately 8 miles. I had a little more input information this go round. After about four days of searching it was finally discovered, KI4NHK, K4MCD and myself and others participated in the hunt. KI4NHK ultimately found the payload. It was up 40-50' in a tree. We tried with dusk fast approaching to retrieve the load. No luck. KI4NHK arranged for the payload to be retrieved by a climber with gear and experience.

Several balloons were launched this year leading up to the Eclipse event on 08/21/2017.  As I was tracking via aprs and hf/vhf/uhf it was at times confusing as I watched three or more balloons at once. The aprs signals were intermittent on one or more of the balloons. One of the last beacons on aprs was @

2017-08-19 12:56:09
7 MPH 86° alt 4689 ft

You would think this would be easy to locate, right? Wrong. Even with aprs tracking, the terrain, heat, access, property owners, dogs, snakes, horses, cows, spiders, sweat, the list goes on. ad-infinitum. It's a great challenge to locate and retrieve a balloon and it's payload, however there are lots of lesson you learn every time out. So here goes.

1. Safety Safety Safety
2. Is it worth it?
3. Liability
4. Trespass Laws
5. Wrong end of the GUN
6. Poisonous Critters
7. Crevasses/holes
8. Daylight
9. Where am I, exactly?
10. How long will it take for help to arrive if something happens?
11. I have a radio and a net control station, but what if battery fails, no signal, rainstorm pops up, I trip on log and sprain my ankle and cannot get to my radio. There is no phone signal here. I'm down in extreme pain and at least 3/4 miles deep into the woods. I'm bleeding pretty badly.
Okay you get the idea. Right

Now another scenario. There are 4 of you circling around in the wide open field, the Johnson grass is head high and above. No luck looks like it may be over there and we all head off to the woods where there is a drop off by the river. It's extremely hot. We are in contact with Net Control, they know the general vicinity of our hunt. All hunters are off on their own hurriedly trying to be the finder of the GREAT Prize. Payload discovered.
Payload up in a tree about 30', Somebody very quickly grabs tree and begins to climb. Just about the time she reached out to grab payload she was stung in the neck by a couple yellow jackets. As she reacted the half rotten limb she was standing on gave way. Down she went being mangled by each limb on the way down. Oh but she managed to hang on to the payload.

So Guys and Gals the message here is Use Your Hat Rack. Is it worth it? There's lots of ways to do things, and there are consequences to the steps that we take. Who is responsible for YOU? No not Net Control. You are responsible for YOU.

SAFETY SAFETY SAFETY
Think Think Think

So you got the balloon, how much did it cost you? So Net Control is sitting back in the comfort of a nice air conditioned shack looking at an aprs screen sipping a cool drink and you are in the woods dealing with everything from a loaded shotgun with an angry land owner to rattlesnakes in search of water, chiggers, ticks, spiders, caves, sinkholes, other hams racing to find the PRIZE.
The responsibility falls on the individual ham or hunter.
Be careful and move slowly. Now that's what could happen. But then again everything may work out perfectly and the payload makes it back home to its launcher and everyone lives Happily Thereafter.

Solar Radiation Management / Geo Engineering

posted Aug 2, 2017, 5:53 PM by Stones River   [ updated Aug 7, 2017, 9:52 AM ]

Geoengineering / Solar Radiation Management / Drought

What if there were a monumental environmental threat that you didn’t even know was happening? What if you found out it is affecting your health and that of people you know and love? What if you knew it was such an enormous problem that it has the potential to destroy our crops and trees, the soil they are grown in, our entire water supply, and whole ecosystems – and that if you didn’t act, we could never turn back?

We are not talking about fracking, nuclear energy, or the oil industry. We’re not even talking about climate change.


Readyville, Tennessee 08/05/2017


What if it came into use in an insidious way, just as GMO foods have come into our food supply without our knowledge? What if it appeared to be harmless, but it wasn’t? And what if it were so cleverly woven into our culture that we didn’t even see it anymore? What if it were so masterfully stigmatized and wrapped in controversy that if you thought it strange or concerning, you’d be scorned or ignored?

It sounds like science fiction, but it’s not. It’s happening right above you, and it’s called “geoengineering”.

You can find articles and debates in which scientists are proposing to “dim” the sun to slow down climate change, using a technique called “Solar Radiation Management” (SRM). Their concept is to mimic the dimming and cooling effects of a volcanic eruption and existing particulate pollution made by human activity. However, it has been out of the proposal stage for quite some time, and even though officials will not admit it, SRM is already in full-scale operation.

SRM sounds like a viable solution to slowing climate change, and scientists have repeated how “cheap” it is over and over again. But it comes with a price. In fact, it comes with many.

Global climate engineering/geoengineering programs are radically disrupting weather patterns, disrupting the hydrological cycle (causing drought in some areas, flooding others), destroying the ozone layer, and contaminating the entire planet with the toxic fallout from these atmospheric spraying operations.

Climate engineering programs have been fully deployed for many years. There is a mountain of hard science data and film footage to back up this statement of fact. All available data indicates that the ongoing global geoengineering programs are mathematically the greatest single assault against the web of life ever launched by the human race. To interfere with Earth's life support systems is insanity beyond comprehension and this is exactly what the completely out of control military industrial complex has done. There are no regulations on these atmospheric spraying programs, and no oversight whatsoever. We are all currently being subjected to these ongoing tests.

FCC Part 97 : Sec. 97.205 Repeater Station

posted Jul 26, 2017, 12:52 PM by Stones River   [ updated Jul 27, 2017, 2:21 PM ]

US repeater coordination

Repeater coordination is not required by the Federal Communications Commission, nor does the FCC regulate, certify or otherwise regulate frequency coordination for the Amateur Radio Bands.

Amateur Radio Repeater Coordinators or coordination groups are all volunteers and have no legal authority to assume jurisdictional or regional control in any area where the Federal Communications Commission regulates the Amateur Radio Service
. The United States Code of Federal Regulations Title 47 CFR, Part 97, which are the laws in which the Amateur Radio Service is regulated clearly states the definition of Frequency Coordinator.

The purpose of coordinating a repeater or frequency is reduce harmful interference to other fixed operations. Coordinating a repeater or frequency with other fixed operations demonstrates good engineering and amateur practice.

Amateur Radio Repeater     PART 97—AMATEUR RADIO SERVICE


Part 97 : Sec. 97.205 Repeater station

(a) Any amateur station licensed to a holder of a Technician, General, Advanced or Amateur Extra Class operator license may be a repeater. A holder of a Technician, General, Advanced or Amateur Extra Class operator license may be the control operator of a repeater, subject to the privileges of the class of operator license held.

(b) A repeater may receive and retransmit only on the 10 m and shorter wavelength frequency bands except the 28.0–29.5 MHz, 50.0–51.0 MHz, 144.0–144.5 MHz, 145.5–146.0 MHz, 222.00–222.15 MHz, 431.0–433.0 Mhz, and 435.0–438.0 Mhz segments.

(c) Where the transmissions of a repeater cause harmful interference to another repeater, the two station licensees are equally and fully responsible for resolving the interference unless the operation of one station is recommended by a frequency coordinator and the operation of the other station is not. In that case, the licensee of the non-coordinated repeater has primary responsibility to resolve the interference.

(d) A repeater may be automatically controlled.

(e) Ancillary functions of a repeater that are available to users on the input channel are not considered remotely controlled functions of the station. Limiting the use of a repeater to only certain user stations is permissible.

(f) [Reserved]

(g) The control operator of a repeater that retransmits inadvertently communications that violate the rules in this part is not accountable for the violative communications.

(h) The provisions of this paragraph do not apply to repeaters that transmit on the 1.2 cm or shorter wavelength bands. Before establishing a repeater within 16 km (10 miles) of the Arecibo Observatory or before changing the transmitting frequency, transmitter power, antenna height or directivity of an existing repeater, the station licensee must give written notification thereof to the Interference Office, Arecibo Observatory, HC3 Box 53995, Arecibo, Puerto Rico 00612, in writing or electronically, of the technical parameters of the proposal. Licensees who choose to transmit information electronically should e-mail to: prcz@naic.edu.

(1) The notification shall state the geographical coordinates of the antenna (NAD–83 datum), antenna height above mean sea level (AMSL), antenna center of radiation above ground level (AGL), antenna directivity and gain, proposed frequency and FCC Rule Part, type of emission, effective radiated power, and whether the proposed use is itinerant. Licensees may wish to consult interference guidelines provided by Cornell University.

(2) If an objection to the proposed operation is received by the FCC from the Arecibo Observatory, Arecibo, Puerto Rico, within 20 days from the date of notification, the FCC will consider all aspects of the problem and take whatever action is deemed appropriate. The licensee will be required to make reasonable efforts in order to resolve or mitigate any potential interference problem with the Arecibo Observatory.

Amendment of Part 97 of the Commission's Amateur Radio Service Rules to Permit Greater Flexibility in Data Communications



"The Amateur Radio Emergency Service (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment for communications duty in the public service when disaster strikes. Every licensed amateur, regardless of membership in ARRL or any other local or national organization, is eligible for membership in ARES. The only qualification, other than possession of an Amateur Radio license, is a sincere desire to serve. Because ARES is an amateur service, only amateurs are eligible for membership. The possession of emergency-powered equipment is desirable, but is not a requirement for membership."

"Simplex is the Heart of Ham Radio" k4pew
Lurkers, Lollygaggers and Sandbaggers Welcome

A couple years ago K4PEW Paul started what is now known as the Mt. Juliet Simplex Net. Who can you talk with in your area without the use of a repeater? Why Simplex when we have all these repeaters? Well answers to questions like that are exactly what a simplex net can offer. Here is one scenario, Repeaters are down from east to west all across the state as a result of last nights storms. Or maybe the Trustee of several repeaters has died and no one else has the codes or keys. A planned targeted attack on all repeaters in your area by disgruntled or slighted club members. Or just something as simple as a squirrel got caught eating his nuts on the incoming power lines. We certainly are spoiled with the repeaters that seem to always be there up and operational. But WHAT IF? It is not surprising in today's world to see Hams that cannot change the input tone on some of these radios. Where is that manual? Oh I cannot input frequencies unless I have a specific usb cable, computer, and proprietary software. These are just some of my thoughts as I think on the subject of SIMPLEX Radio. K4PEW has put a lot of Heart into this up and coming Simplex Net. Join the Mount Juliet Simplex Net if you are in the area.

Learning About Repeaters

posted Aug 26, 2016, 4:49 PM by Stones River   [ updated Aug 26, 2016, 4:54 PM ]

Well if you are anything like me you might have lots of questions about Ham Radio repeaters. Who owns them, who's controls them, how are they linked, do they have to be monitored by the trustee while on the air as a transmitting repeater, if there is a stuck repeater who is responsible to find and fix the problem? The list goes on and on. Can my ARES group get a repeater pair and if so what steps do we take? A few links below are where I have found some very useful information.


1. Tidbits below credit from>   http://www.arrl.org/auxiliary-station-faq
  • How does the FCC define a repeater?

    A repeater station is an amateur station that simultaneously retransmits the transmission of another amateur station on a different channel or channels [97.3(a)(39)]. Only repeaters, some types of auxiliary stations, and space stations may automatically retransmit the radio signals of other amateur stations [97.113(f)]. Holding your mic in front of the loudspeaker of a receiver so you can retransit the signals of another station is not "automatic," so this is not "repeater" operation.


Does the control operator of an automatically controlled repeater have to listen 24 hours each day?

No, but a controller cannot detect and correct improper use of the repeater. The licensee is always responsible for the proper operation of the station, Part 97 states The control operator of a repeater that retransmits inadvertently communications that violate the rules in this Part is not accountable for the violative communications [97.205(g)]. In the event of improper use of the machine, the licensee is responsible for correcting the problem as soon as practicable and for making sure that the problem will not happen again. 

  • What other repeater rules are there?

    In addition to the somewhat complex rules mentioned thus far for repeaters, amateurs must be aware of a few more, though simpler, repeater station rules: 1) A Novice licensee may not operate, or be the control operator of a repeater [97.205(a)]. 2) Repeaters may operate on any frequency authorized to the Amateur Radio Service above 29.5 MHz except for 50.0 - 51.0, 144.0 - 144.5, 145.5 - 146.0, 222.0 - 222.15, 431 - 433 and 435 - 438 MHz [97.205(b)]. Note that these frequencies include both the input and output frequencies of all repeaters. 3) If there is an interference problem between two repeaters on the same frequency, the two repeater licensees must work together to solve an interference problem between the repeaters, unless one repeater is coordinated and the other is not. The licensee of an uncoordinated repeater bears the primary responsibility for solving an interference problem [97.205(c)]. 4) If the control operator is someone other than the licensee, both are equally responsible for the proper operation of the station [97.103(a)]. 5) The licensee and control operator(s) of a repeater that inadvertently retransmits communications which violate the rules in Part 97 are not normally held accountable for the violative communications [97.205(g)]. However, they will be held accountable if they become aware of the illegal communications and allow them to continue, because they are no longer "inadvertent." They must make an effort to prevent such communications from continuing. If they are unsuccessful, they must shut the repeater off until the problem can be corrected. The operator of the station originating the illegal communications will be held accountable at all times by the FCC. 6) Before establishing a repeater within 10 miles of the Arecibo Observatory in Arecibo, Puerto Rico, the facility must be notified [97.205(h)].


What is Frequency Coordination?

Although it is not "required" by the FCC rules, most repeater operators coordinate the input and output frequencies for their repeaters, as well as any auxiliary link and control frequencies, with their local or regional frequency coordinators. The FCC defines a frequency coordinator as An entity, recognized in a local or regional area by amateur operators whose stations are eligible to be repeater or auxiliary stations, that recommends transmit/receive channels and associated operating and technical parameters for such stations in order to avoid or minimize potential interference [97.3(a)(22)]. The primary function of frequency coordinators is to help amateurs, who desire to put up new repeaters, in selecting frequencies which will cause, and receive, a minimum amount of interference within the limited number of repeater frequency pairs available. Coordinators are volunteers who serve with the approval of the amateurs within their region. They have no authority to "assign" frequencies - they make recommendations. They maintain an accurate database of information on every coordinated station within their area (this data is held in strict confidence), and they use this data in forming their recommendations. If repeater users do experience harmful interference, coordinators are happy to assist in resolving the problem. The FCC considers frequency coordination to be "good amateur practice".

The primary function of frequency coordinators is to help amateurs, who desire to put up new repeaters, in selecting frequencies which will cause, and receive, a minimum amount of interference within the limited number of repeater frequency pairs available.


  • What is the difference between a repeater licensee and trustee?

    If the repeater or remote base is operating under the auspices, and using the callsign of an individual amateur's personal station license, then the operator is the "licensee" of the station, not the "trustee." If it is operating under the auspices of an FCC-issued club station license, and using the FCC-issued club callsign, then the person whose name appears on the license is the "trustee," not the "licensee."

Q. I can’t find anything in Part 97 to cover this: Two interconnected repeaters with different call signs. Each one repeats the call sign of the other. Is that OK?

A. It can be. There is no rule prohibiting interconnected repeaters but there is a how-to challenge in making proper Section 97.119 station identification announcements. No station may transmit as the station call sign any call sign not assigned to the station. It must be made clear for our Maintenance Monitors and other listeners which call sign is for which station.

Q. Our repeater transmits under automatic control. Doesn’t that excuse me from some degree of accountability?

A. No. Section 97.3(a)(6) automatic control is the use of devices and procedures for control of a station when it is transmitting so that compliance with our rules is achieved without the control operator (you) being present at a control point. If your use of devices and procedures isn’t getting the job done properly, you shouldn’t be relying on them. Read Part 97 & Automatic Control BE Informed No. 8.4.

A. Yes. Section 97.5(a) can only mean that the Section 97.103 station licensee must be a living person with the capability of having the station apparatus under physical control. If your repeater is one that hams rely upon regularly such that even its temporary loss would disrupt their activities, you should have a backup plan at the ready in case of an unexpected need.

5. Is frequency coordination required?
No. Participation in a frequency coordination program is strictly voluntary. No Amateur Radio frequency coordinator has any "authority" to tell a repeater sponsor what he can, or cannot do. However, the Federal Communications Commission (FCC) and the amateur community has recognized that participation in a frequency coordination program by repeater sponsors is in the best interests of all Amateurs. Therefore, FCC rules (Part 97.205c) have been adopted which state that the sponsor of an uncoordinated repeater bears the primary responsibility for curing any interference between his repeater and another repeater which is coordinated. Likewise, the sponsor of an uncoordinated machine cannot expect much help from his area frequency coordinator.
