- │ WHAT IS A VIDEO NOTCH FILTER ? │
- │ │
- │ The pictures and sounds on your TV are carried there by signals. │
- │ Each signal travels down it's own path, or channel. A notch filter │
- │ is used to block the path of an unwanted signal. This prevents │
- │ the signal from delivering its information to our TV screen. │
- │ The filter acts as sort of an "Electronic Roadblock" to the │
- │ unwanted signal, while allowing all others to pass freely. │
- │ USES OF A NOTCH FILTER. │
- │ (elimination of channels) │
- │ │
- │ This function is useful for parental censoring of Adult Channels. │
- │ Even if scrambled by the cable company, they may be somewhat │
- │ watchable. This is not the case when a notch filter is used. │
- │ The notch filter may be used to block the path of an unwanted │
- │ channel's signal. The signal then cannot carry its picture to the │
- │ TV screen, and the channel is ELIMINATED. │
- │ ═════════════════════════════════════════════════════════════════════ │
- │ TO ELIMINATE MILD OR SEVERE INTERFERENCE. │
- │ ───────────────────────────────────────── │
- │ Interference occurs when some unwanted signal gets into the │
- │ path of the desired signal. As a result, both signals reach the │
- │ TV screen. One carries the clear picture you want, but the other │
- │ brings along unwelcome interference. A notch filter may be used │
- │ to block the path of the unwanted signal, while allowing the │
- │ desired signal to pass freely. As a result, the interference is │
- │ removed and all you see is the clear picture. │
- │ ╔═══════════════════════════════════════════════════════════════════════╗ │
- │ ║ UNWANTED SIGNALS ║ │
- │ ║ ║ │
- │ ║ Unwanted signals may find their way into your TV in many ways. ║ │
- │ ║ Some ways are unintentional. Ham Radio operators create them ║ │
- │ ║ by using their radios quite by accident, and there are many other ║ │
- │ ║ ways to introduce interference accidently. Sometimes interference ║ │
- │ ║ is put in the path of a signal to block it, as we discussed earlier. ║ │
- │ ║ In fact, your local cable company probably uses it to block certain ║ │
- │ ║ channels they want you to pay additional money to receive (HBO, ║ │
- │ ║ SHOWTIME, CINAMAX, ect). To remove this interference, they either ║ │
- │ ║ install a NOTCH FILTER, or turn on the one in your converter box ║ │
- │ ║ by remote control. ║ │
- │ ╚═══════════════════════════════════════════════════════════════════════╝ │
- │ THE LIMITATIONS │
- │ │
- │ Notch filters can do many good things, but there are limitations: │
- │ 1) they can't fix every type of "interference". │
- │ 2) It would be illegal to use them to remove the cable company's │
- │ intentional interference ( Although they can!! ). │
- │ THE TEST │
- │ ┌──────────────────────────────────────────────────────────────────────┐ │
- │ │ The filter CAN allow normal reception of a channel that is presently │ │
- │ │ unwatchable if ... │ │
- │ │ │ │
- │ │ 1) There is an unusual pattern on the screen, which partially or │ │
- │ │ completely hides the picture. │ │
- │ │ 2) This pattern looks the same on the left half of the screen as it │ │
- │ │ does on the right half, at all times (Zig zag lines or snow). │ │
- │ │ 3) The patern is accompanied by an unusual sound. This sound may │ │
- │ │ be a humming, buzzing, shrill, alternating, or garbled sound. │ │
- │ └──────────────────────────────────────────────────────────────────────┘ │
- │ HOW TO ORDER │
- │ │
- │ 1) Determine the channel number that you wish to block or clear. │
- │ 2) Make sure it meets the requirements of the test or write or call │
- │ us and describe what you see and hear on that channel, if you │
- │ aren't sure.(See GUARANTEE) │
- │ 3) Fill out the form below. │
- │ 4) Add the charges in the columns on the right. │
- │ 5) Mail the form along with a check or money order to the address at │
- │ the top of the form.(Delivery in two weeks or less in most places) │
- │ **** THE GUARANTEE **** │
- │ IF FOR ANY REASON YOU AREN'T SATISFIED RETURN THE FILTER FOR A REFUND! │

- │All filters are made from top quality parts and are tested before they are │
- │shipped to you. I have ordered filters like mine from many other companys │
- │and I found them all unacceptable, with only one acception, the picture was │
- │grainy (bad). My filters deliver fantastic picture quality because I use │
- │top quality parts in them. │
- │ │
- │NORMAL FILTERS- Are made with single turn fine tuning and high impact │
- │plastic enclosures. Tuning instructions and tuning tool included. │
- │ │
- │DELUXE FILTERS- Are made with Air Dielectric tuning and multiple turn fine │
- │tuning and high grade aluminum enclosures. Tuning instructions and tuning │
- │tool included. │
- │ │
- │KITS- Include all parts including printed circuit board to assemble a NORMAL │
- │FILTER. Tuning tool and instructions included. Some knowledge of basic │
- │electronics (soldering) required. │
- │ │
- │PLANS- Includes a schematic and parts list. │
- │ │
- │TUNING TOOL- Basically a plasic screwdriver. (It's good to have a spare one)│
- │ │
- │ NOTE: │
- │Filters work on one channel at a time and must be tuned for each new channel.│
- │If you have a converter box (NOT A VCR) all you will need is F111. F111 will│
- │clear multiple channels with a converter (IT WILL NOT WORK WITH A VCR!!!).│
- │Using any tuning tool other than the CAT# T1 may result in damage to the │
- │filter. │
