JP1 Remotes

Code 994 works like a charm.

After you do programming like that on the remote itself, remember to do a download back to IR.exe and save the file, so you have both a backup and a starting point for any future change you want to make in IR.

Already done. It had occured to me that doing a couple ...

You can look up the EFC numbers of the vol commands for your TV, then assign them as KeyMoves using IR.EXE (or assign them as KeyMoves using the 994 command on the remote and you won't need to look up the EFC numbers). That is only needed if you decide not to change the device type of the upgrade ...

OK, new problem. The VPT isn't working correctly now that I've applied this upgrade. It doesn't work for the aforementioned Tivo code, but for every other code on the remote it works fine. I also cannot learn the codes from my TV on that code (VCR 0618). I can store those keys (Vol+, Vol-, and Mute ...

BTW, just curious, does the fact that the lifespan of the diode is increasing mean that the remote is simply speeding up the signal to achieve the higher frequency (thereby shortening the amount of time it is flashing)? How does the increase amount of energy that passes through the diode affect its ...

I got you. We're comparing two different things. When comparing the duty cycles of two different objects which can perform different unit/amounts of work in some fixed time unit (day), then the one with the longer duty cycle could last longer and might be more economical in the long run, then the ...

Oh. Interesting use of the term duty cycle. With copiers, duty cycle refers to the number of times per unit of time that a particular part must be changed and therefore the cost per unit for each copy made and the ultimate lifespan of the copier. Higher duty cycles (measured in pages printed) in ...

Frequency change works as well.

Which solution should I use? Don't know if I want to risk harming my remote...

Putting a piece of paper in font of the IR receiver works. Kinda tacky looking, and it does reduce the effectiveness of the IR extender. What a dilima...

The URC-7800 does have two diodes, though. Which probably explains why it works when at an angle. Upon further testing, only one diode is pointed ...

If you want to raise the frequency a little (and lower the duty cycle) for that upgrade, change the first two bytes of the protocol upgrade from "43 8D" to "3D 92". That's my best guess of what the learned signals would be using.

If you want to confirm that the 7800's signal is too strong, you ...

URC-7800 with the VCR 0618 code that I downloaded from the files section (with no modificatio). It is the Tivo Master File ( https://www.hifi-remote.com/forums/dload.php?action=download&file_id=791 )

The Remote is a new one that I just bought from Rob. When I try to use this upgrade code I noticed ...

Thanks.

I went ahead and bought two urc-7800's from Rob. Still looking for one, though. If anyone has a spare. Very hard to find, and their prices tend to skyrocket on E-bay.

Hey,

Anyone know where I can find two of these remotes? My URC-7800's (which both my wife and I LOVE) are dying. Buttons are failing, functionality is being lost. Is someone on this list selling them by chance?

Long Yahoo URLs...got it.

No progress, I've now got to change the head gaskets on my car. So, don't expect an immediate response. Sorry.

Jon,

Thanks. I'm horribly out of practice, but I will give it a go. That particular learned funcion you are talking about that seems cut off, I've tried to correct several times on both remotes (if you remember me, I'm the guy with two of these). It shows up the same every time. *shrug*

It's ...

Jon and John,

Here is the new file.
