Rf signal sometimes I cant get rf signal, what should i do

Hi Henrey,

is it happens recently or in the beginning you brought the tv .

please let us know.
sometimes it can be a back light circuit problem.
regards,
nuwan.

If you're still getting loud squelch noise but do not receive on any channel, you must check the RF from the antenna to the audio stage(not included). There must be more than just one RF stage in this radio. Let me know what you find.

thats a hardware problem, your RF amplifier should be weak. it is responsible for amplifying and mentaining the signal on your phone. you should therefore take it to a service point so that they check it anf if possible replace it.
Regards

Your fan receives RF signals from the remote for control. It may be picking up stray RF signals from a neighbor. Try re-programming your fan/remote to a different frequency.
(RF=radio frequency)

These switches have an RF operating range of about 50', according to the manufacturer's spec. It is unlikely the neighbors are tripping them. Look around your neighborhood for a ham or CB antenna. That could do it.

Also, these switches run through the AAA batteries pretty fast. You might check them.

50' is not much range for an RF signal. You may take a look at Insteon, which have about a 200' range. Also, they create a "dual mesh" signal by mixing RF with the electrical current in the lines in your house.

Most DirecTV receivers are able to be controlled with IR (infrared) or RF (Radio Frequency) signals. DirecTV receivers are usually set to be controlled by RF.

To control a DirecTV PVR / Satellite, it needs to be set to respond to an IR Remote:
1. On the original DirecTV remote press the Menu button
2. From the Menu press Select on Settings
3. Select Remote from the left menu
4. Press Select on the IR/RF Setup button
5. Use the Up or Down arrows to change from RF to IR
6. Press Select to save

Note: Some models of DirecTV may have different steps to enable IR. You may need to refer to your user manual


Harmony Remotes only control IR signals. so this is not the issue. The Harmony Remote should control the tv. the original remotr needs to be tested for IR or RF.

The device we are working on that is not being controlled by the Harmony Remote could be operating on RF (Radio Frequency) signals. Harmony Remote can only control the devices that operate on IR (Infrared) signals. Most devices that work on RF signals can be changed to operate on IR signals, and this usually could be done by changing the remote control command mode to IR from RF.
Please follow the steps listed below to test to see if the device is being operated on RF or IR signal:
1- We need to use the original remote for that device to complete this task
2- Using your hand or a thick and wide object (wall, pillow, book...), cover the top part of the original remote. In other words block the direct positioning between the original remote and the device.
3- After you cover the top part of the original remote (or used an alternate way to block the direct communication of the original remote and the device), try pressing the buttons on the original remote to see if it can still send commands that can be received by the original remote. You can try powering on/off your device using the original remote when the original remote is being blocked by your hand or another object.
4- If you still can control the device using the original remote without a point of sight, your device is being operated on RF signals. If you cannot control the device without a point of sight, then it is IR operated.
5- If the device is RF operated, please change the command receiving mode to IR rather than RF and test the Harmony Remote.
6- If the device is IR operated, please contact us again by replying to this email and let us know if none of the commands or some certain commands are not working for that device.

You can usually find the information on how to switch the device to be operated on IR signals rather than RF signals, through the user manual for your device, or by contacting technical support of the manufacturer for that device, or even sometimes reaching the information simply by doing a basic research over the internet.

instead of plugging in the rf modulator before the cable box, i plugged it in after it

Could anything other electronics be interfering with the signal?

Hi.

At the back of the box there will be 2 rf outputs.
What you are looking for is the rf output 2. What you need to do is connect a rf cable from rf output 2 into the magic eye,which in turn plugs into the rf input on the tv.
To make sure that the 9v signal is being passed up the cable(this is what allows the magic eye to work)
go into services on the SKY guide the press 4(system set up) then 01 select. This will give you access to the installers menu. Press 4 (rf outlets) and then make sure that power supply is ON. Save new settings.
This will now let you use a magic eye.

OK the tuner may be causing these problems, however first I would like you to go to your menu and set the RF pickup to antenna (This will allow analog channels) then come out of the memu and select a channel in the analog range channel 4, 7, or 9 try to tune in these channels. If this fails then you may have tuner problems the only way to be sure is to use a RF signal generator to send RF through the tuner and see if the video and audio being carried on that signal comes through. Sometimes the Internet connect gets messed up when the TV does not have the proper RF filters this may be your case. Try this use a Cable tv set top box and just set your TV to channel 3 for cable. This should Isolate the TV from the Internet cable modem and provide the signal needed by the TV.
