Anyone have an of course un-official channel line up for the FBI?

Joined Jul 8, Messages 10, Location Taxachusetts. It would be nice if it were that simple. The problem is that every area of the country has a different channel plan. The other channels they use could be almost anywhere in the band. And then there are the inputs to the repeaters usually lower in the band around and When they need more channels then what they can use in the section, they start using unused DOJ pool frequencies that are scattered from to You might be able to get someone in your area on the Regional Forum who can help you.

Most of us "regulars" here search all the time looking for everything. My local list is HUGE, but it would not help you much where you are. If you look at the old posts for this forum, I used to be more regular here than I am now.

Actually I kept trying to get this forum created. I understand what you're saying and I know that what you have might not be correct here, but I was just trying to get a general list and can go from that.

I took a long break myself. Just got beck into it when P25 scanners with NAC decode came out. I can PM you my list if that helps. Last edited: Aug 19, Phil, thanks again!! Joined Feb 24, Messages 0 Location Virginia. PM sent. Here are some of the inputs to the repeaters.

Thanks guys. I just wanted something to compare to what I have right now. Hell, I had from some list that Wait a while before I post what I find. AlabamaRS said:. Here is the frequency pool I have, but as noted, the channel lineup is different from office to office. It is exciting to listen into surveillance, but never go to the area if known. Just kick back in your home or office and enjoy what you hear.Other equipment also accesses the same channels, such as Bluetooth. The radio frequency RF spectrum is vital for wireless communications infrastructure.

The Those are also numbered by the centre frequency of the bonded group. Countries apply their own regulations to the allowable channels, allowed users and maximum power levels within these frequency ranges.

List of WLAN channels

The ISM band ranges are also often used. Each world region supports different sub-bands, and the channels number depends on the starting frequency of the sub-band it belongs to. Thus, there is no global channels numbering plan, and the channels numbers are incompatible between world regions and even between sub-bands of a same world region.

The following sub-bands are defined in the Fourteen channels are designated in the 2. Nations apply their own RF emission regulations to the allowable channels, allowed users and maximum power levels within these frequency ranges.

Network operators should consult their local authorities as these regulations may be out of date as they are subject to change at any time. Most of the world will allow the first thirteen channels in the spectrum.

While overlapping frequencies can be configured at a location will usually work, it can cause interference resulting in slowdowns, sometimes severe, particularly in heavy use. Certain subsets of frequencies can be used simultaneously at any one location without interference see diagrams for typical allocations :. However, the exact spacing required when the transmitters are not colocated depends on the protocol, the data rate selected, the distances and the electromagnetic environment where the equipment is used.

The overall effect is that if there is considerable overlap between adjacent channels transmitters they will often interfere with each other. However, using every fourth or fifth channel by leaving three or four channels clear between used channels can cause less interference than sharing channels, and narrower spacing still can be used at further distances.

The most commonly used channels are 22 and This is to avoid interference with weather-radar and military applications. European standard EN covers 5. Source for South Africa: [35]. In Brazil, the TPC use in 5. DFS is required only in the 5. As of [update]some of the Australian channels require DFS to be utilised a significant change from the regulations, which allowed lower power operation without DFS.

New Zealand regulation differs from Australian. Operating 5. They allowed MHz channel bandwidth from The 2. A Federal Communications Commission FCC document clarifies that only channel 14 is forbidden and that low-power transmitters with low-gain antennas may operate legally in channels 12 and In Canada, 12 channels are available for use, 11 of which at full power and the other channel 12 is transmit power limited.

Few devices, however, have a method to enable a lower powered channel Is atrial fibrillation serious? People who are old enough to remember the sound of wind-up clocks often refer to their hearts as their "tickers.

In fact, though, the healthy heart is much more sophisticated than the most precise Swiss timepiece. Instead of maintaining a single, monotonous beat, the heart can speed up in response to exercise, strong emotions, and fever. Common chemicals can also jack up the heart rate ; examples include caffeine, nicotine, and decongestants.

And the healthy heart can also slow down when you rest, relax, or sleep. A clock keeps a steady rate of 60 beats per minute, while your heart rate may vary between 50 and beats at rest and rev up to twice as fast during exercise. But sometimes the mechanisms that regulate the rate and rhythm go awry. Doctors call these disorders arrhythmias; they come in many varieties, but the most common sustained arrhythmia of all is atrial fibrillation AF.

AF is a new concept for many men, but it's plagued men's hearts for millennia. In fact, the first written description dates back to China some 4, years ago. An English physician named William Withering discovered the first useful treatment for AF in when he gave the leaf of the foxglove plant Digitalis purpurea to a patient whose pulse became "more full and regular.

And more than a century later, the treatment of AF continues to evolve and improve, providing important benefits to many people, but introducing many complexities for both doctors and patients. The human heart is divided into four pumping chambers see figure. The two upper chambers are called the atria; they collect blood from the veins, then pump it into the two ventricles, larger and stronger chambers that propel the blood out from the heart to the rest of the body.

To function best, the atria should contract first, with the ventricles close behind. The electrical messages that signal the heart muscle to contract begin in the atria at the SA nodeand then travel across the AV node into the ventricles to trigger the contractions you feel as your pulse.

The entire sequence can be recorded on an electrocardiogram ECGwhere the atrial contractions appear as P waves and the ventricular contractions that follow show up as QRS complexes see figure. When the heart is in its normal rhythm, the atria contract at steady, regular intervals. But in AF, the atria's electrical signals occur much more rapidly, often to times per minute. At these rates, the muscle just can't contract in a coordinated fashion. Instead of producing an atrial beat, the muscles just quiver fibrillate ineffectively.

The ventricles are bombarded by fast, irregularly spaced atrial impulses, but they are partially protected from breakneck speed by the AV node, which intercepts the atrial impulses and blocks many of them before conducting some to the ventricles.

Still, the ventricular rate is usually much faster than normal, and the rhythm is irregular, as is your pulse.

In normal sinus rhythm, the sinus node initiates the electrical activity that triggers each heartbeat. The electrical impulse travels through the atria, signaling the muscle to contract; each atrial contraction shows on the ECG as a p wave. The electrical activity then crosses into the ventricles, stimulating them to contract and pump blood to the body's tissues shown in ECG as the QRS complex.

In atrial fibrillation, the atria's electrical signals are very rapid and erratic; the atria don't contract and there is no p wave. Without a coordinated signal to guide them, the ventricles contract at a rapid rate in an irregular rhythm. Scientists don't fully understand the basic problems behind AF, but they do know many of the factors that increase the risk of AF.

Since about a third of all patients with AF have a family history of the disorder, heredity also plays a role, and several specific genetic abnormalities have already been identified.The Fibonacci channel is a technical analysis tool that is used to estimate support and resistance levels based on the Fibonacci numbers. It is a variation of the Fibonacci retracement tool, except with the channel the lines run diagonally rather than horizontally.

It can be applied to both short-term and long-term trends, as well as to uptrend and downtrends. Lines are drawn at A Fibonacci channel doesn't require a formula. The channels are drawn at certain percentages of the price move selected by the trader. In order to draw a Fibonacci channel, the trader must first determine the trend direction. To draw the channel in an uptrend requires finding two swing lows and a high point in between.

To draw the channel for a downtrend requires finding two swing highs and a low point in between. The distance between the high and low creates the measurement for where the Fibonacci channels which are percentages of the measurement selected will be drawn. Parallel lines are drawn at the key Fibonacci levels of If there are significant trends, traders can also extend the levels beyond percent, such as Traders can create Fibonacci channels on most major charting software platforms, although the implementation of them is subjective since traders have discretion on which highs and lows to use for drawing their Fibonacci channels.

The tool is used to aid in identifying where support and resistance may develop in the future. The same concept applies to downtrends if a downtrend is expected to continue. In an uptrend, the zero-line is like a normal trendlinehelping to assess the overall trend direction.

If the price falls below it, it may need to be adjusted based on more recent price action, or it could signal that the uptrend is over and that the price is breaking lower. In a downtrend, the zero-line also acts like a trendline. When the price is below it, it helps confirm the downtrend. If the price moves above it, the indicator may need to be redrawn or the price is moving higher out of its downtrend. A price that moves to the Both these indicators attempt to predict future support and resistance levels based on price levels from the past.

Fibonacci channels attempt to do this with percentages of a selected price move.

Those percentages are then projected out into the future. Andrew's Pitchfork is simpler in some ways as the angled lines are based on three price levels selected the trader and then extended out into the future.

While multiple Fibonacci levels and indicators can be added to a chart, they can quickly clutter it. As each price wave forms a new Fibonacci channel will provide new information. Fibonacci channels are highly subjective.

The trader chooses three points they deem to be significant, yet the market may not view these points as significant and thus may not respect or react as expected to the drawn levels.

One of the complaints with Fibonacci analysis, in general, especially on short-term charts, is that there are so many levels that the price is likely to reverse at or reach one of the levels.

The problem is knowing which level will be important in advance. For this reason, traders are encouraged to use other forms of analysis, such as price action and other technical or fundamental indicators, to aid in their trading decisions.

Key Takeaways A Fibonacci channel provides the same retracement and extension levels as the Fibonacci retracement and extension tools.Jump to navigation. Some local TV stations in cities across the U. People who watch free over-the-air television with an antenna will need to rescan their TV set each time a station moves to continue receiving the local channel. It's the same scan that you did to find your local channels when you set up your TV or converter box for the first time.

Except in rare circumstances, no new equipment or services are required. Subscribers to cable or satellite TV do not need to rescan. Service providers will do it for you. Many over-the-air TV channels across the U. The actual channel number on your TV will not change.

After the TV is rescanned, it will be the same as before. A change in frequency impacts how a channel is received over the air by your TV. If you watch free over-the-air television with an antenna, you will need to rescan your TV set each time a station moves to a new frequency to be sure your TV recognizes the new frequency when you tune to that channel.

Some local TV channels will be changing frequencies in phases through mid However, because TV channels are moving at different times, you may need to rescan your TV set more than once.

Stay tuned to your local channels for information on when to rescan, as broadcasters will give viewers at least 30 days notice. Refer to our interactive TV reception map to insert your address and see the frequency change timeframe for most local channels in your market.

Whether or not your local TV stations are changing, it is a good idea to rescan periodically — if you haven't scanned your TV recently, you might be surprised at how many stations are now available. Refer to our "Remember to Rescan" video and instructions to learn how to rescan your TV. The call center is staffed from a. Eastern time, seven days a week, to enable consumers throughout the country to obtain assistance during evening and weekend hours.

Rescanning only applies to people who receive their local channels using a TV antenna. Cable and satellite subscribers are not affected.Wireless home networks transmit signals in a narrow radiofrequency range around 2. Electronics such as cordless phones, garage door openers, baby monitors, and microwave ovens may use this frequency range.

The wireless networks of neighbors may use the same radio signaling that interferes with an internet connection, especially in residences that share walls. If your electronic devices or your neighbor's network slow down your home network and internet connection, change the wireless channel on your router so that it communicates on a different frequency to avoid interference. The 2. In most countries, Wi-Fi network equipment provides a set of available channels to choose from.

Wi-Fi equipment in the U. If you encounter interference from other devices in your home, change the channel up or down to avoid it. However, all Wi-Fi devices on a network must use the same channel. Unlike television channels, some Wi-Fi channel numbers overlap with each other. Channel 1 uses the lowest frequency band and each subsequent channel increases the frequency slightly.

Therefore, the further apart two channel numbers are, the less the degree of overlap and likelihood of interference. If you encounter interference from a neighbor's WLAN, change to a more distant channel.

The three Wi-Fi channels 1, 6, and 11 have no frequency overlap with each other. Use one of these three channels for the best results. Newer These frequencies are less likely to encounter wireless interference issues in homes the way 2. Additionally, the 5 GHz Wi-Fi channel choices available in most home network equipment have been selected to choose only non-overlapping channels.

Usable non-overlapping 5 GHz channels also exist between 48 andspecifically 52, 56, 60, 64, and These channels fall into a specially regulated category where a Wi-Fi transmitter detects whether other devices are transmitting on the same channel and automatically changes its channel to avoid conflict.

While this Dynamic Frequency Selection DFS feature avoids interference issues, many network administrators avoid using these channels to minimize complications.

To find the wireless channel your router uses, access the router administration page, usually at the router IP address. Log in to the page, then look for something referring to wireless channels or WLAN.

To see the wireless channel setting, use a mobile or desktop wireless app. The ability to see nearby wireless networks and their channels is crucial. You need to know what the other channels are set at so that you know which channel to change. Wireless interference is only one of several possible causes of a slow network connection. If you've changed the wireless channel but you still have a slow connection, follow these tips:.

Digital television ATSC 1. Instead, your TV keeps a list of which stations are available. Weird, huh? Do you know how old TVs and radios had to be tuned to stations by hand? The TV slowly runs through every possible television frequency, making a list of each available channel along the way.

Naturally, that list needs to be updated every once and a while, and you have to start the scanning process all over again. That means you have to rescan every time you move, every time you buy a new TV or antenna, and every time a local TV station changes to a different broadcast frequency. As a result, all TVs are going to lose track of local channels slowly. The solution? Scan for new channels every month, or every time you notice that a local broadcast goes missing. Scanning or rescanning for channels is mostly an automated process.

All you have to do set that process in motion through a few simple steps. And while these steps are different for each TV, the process is pretty similar on every TV out there.

Admittedly, this is a clunky, somewhat annoying process. Well, they do—kind of. A good radio signal is filled with a mix of loud and quiet parts musicwhile a bad signal is filled with monotonous static or silence. So, most radios have a built-in tuning circuit that simply checks the amplitude response of radio frequencies. In the next decade, ATSC 3. Naturally, channel scanning would be a pain on a handheld device or in a car.

As you move around town or even around your house frequencies will shift in quality and availability.
