Very off topic and inappropriate, but I thought I should mention to my fellow geekish individuals that you should stay very far away from Ellies Electronics' Remote Blaster units.

I own quite a number of things made by Ellies and have always considered them to be a great manufacturer of electronics and A/V equipment, however, they have now changed my opinion of them and their products permanently.

Ellies, in their infinite wisdom, thought that building every single remote blaster transmitter unit to use a 433.92MHz carrier signal and every single receiver unit to use a 433.42MHz VFO would be a very good idea.

I bought a pair of these extenders to treat my dad for father's day and must say I am terribly dissapointed. The house is extremely close to that of a next door neighbour who also owns a pair of said extenders, all though he has the older version. These still work on exactly the same frequency though.

The problem is that since installing them, my dad can not only change his channels from the bed room, but can also watch as the channels are changed at random to something else. When he changes it back, it seems the house is haunted as it changes back to what it just changed to.

It would appear that South Africans have not lost their ability to exceed even my wildest expectations of their stupidity. Since all of the units use exactly the same frequency, if you happen to live within 75m of a neighbour who also uses a set, you will be getting your channels changed and you will be changing his channels.

This would not really have bothered me that much if Ellies took the route of EVERY other manufacturer of remote extender units and included a button to change the channel or frequency of the units. Incredibly, Ellies have included no such button. May be they think it would be a bad idea of users could tune the device to an open channel so that neighbours could peacefully co-exist of both sides own such units.

Instead, Ellies decided to make everybody use the exact same frequencies, I guess it just never occured to them that two people living next door to each other might both want to use these and that it could be a problem if you can't tune the frequency channel.

According to marketing hype on their web site, you could buy the Genius Remote Blaster, which has a digitally encoded serial number with its RF signal. According to them, with the "Genius" unit, you won't get interference from a neighbour's equipment because your receiver will only respond to a signal that carries the serial number of your transmitter.

Of course, this doesn't mean that your neighbour's old unit won't respond to signals from your "genius" unit, so in effect, we would both have to upgrade.

My neighbour had his set first and I can't expect him to upgrade or stop using his gear. Also, I refuse to go and buy a set of "genius" units for both houses, so my dad's father's day gift just has to go back, even though he was ecstatic about it when he could zap the transmitter in his bedroom and see the channels change.

At this point, I have phoned the local Ellies help line and they have been able to offer my no assistance what so ever. I'll be phoning the head office later today but I expect much the same "sorry, buy the genius unit" response.

I'll be returning the extenders I have now anyway and I very much doubt that I will be purchasing the "genius" units or any Ellies products for that matter, for a very long time. It's enough that they are stupid, but since this was meant to be a treat for my dad, they are adding embaracement to extreme annoyance. [:(]

Browsing their site, I also noticed that they are now selling wireless door chimes. I wonder if those all use the same frequency too. I should go buy both our neighbours and myself a set of those so that people ringing his door bell can annoy me too and so that people ringing my door bell can also alert him that I have visitors. Heck, we could probably use our door bells to tap out morse code to each other, great, thanks Ellies.

At the very least, I would have expected them to print a warning on the pack so that I could have anticipated this before giving my dad a present that I will now have to return.

Something like this comes to mind:

--

WARNING: We are dumb as dog manour, we have used the same frequency for all our sub standard remote extender products and offer no way to adjust the frequency used.

If you live close to somebody else that also uses one of these products, you will cause havoc for both households by installing it in your home.

If you want to use this product in denseley populated areas, both households must purchase our "genius" product at a greatly inflated price for the same dodgy equipment, which has a serial number that will at least give some minimal protection against interference, of course, we do not guarantee that the more expensive product will help, it will just be more expensive.

--

Not even the slightest warning about possible interference even appears on the packaging.

Please don't buy Ellies products.

Before alamming a companys products, you have to think about the coutry we live in, thats right Podo, 3rd world country, with a regulator that thinks it can stop all future development, telkoms aside. Since we are all in the tech industry, we all know about ICASA, and their regulations on our presciousssssss airwaves, do you have any idea how much effort it takes a manufacturer to get a license to use a narrow band in his products?
All radio equipment in this coutry has been checked for quality by ICASA, that means they've checked a unit to ensure the frequency/s are licensed by them, and if not, slap a fine on said importer/manufacturer.
I'm sure at ellies, there are some bright folk that would have thought of your problem, and if it was as simple as dual frequency, it would have happened. Something is obviously holding them back, my guess ICASA.

I've found that by decreasing the length of the antenna, I got rid of the "neighbourhood watch" effect. One other thing, although it works fine thru solid walls from 1 side of my house to the other (30m), it's very dodgy outside, having a glass sliding door to negotiate on the way to the receiver (10m). Can't remember the brands though. Have 2 sets, 1 black and 1 grey, working from 2 sender units to 1 receiver

dorris,

I fail to see how it could be impossible for Ellies to have gotten the devices licensed for a narrow frequency band, as opposed to one single frequency. If it were so incredibly difficult, how is it that chordless phone manufacturers, who have ICASA approval, manage to offer anything from 5 to 60 channels depending on the hardware?

If it is absolutely impossible to get a license for a small frequency band, they could at least have had the decency to put some kind of warning label on the product packaging. If that were there, I would not have written my post, because it would have been my own fault. The reason I am slamming their product is because it is of no use to me in the condition in which they sell it.

Luke777,

Good suggestion, sadly it's not an option for me. I use the little "M-Series" extenders. They have a fixed length "wire" antenna that can't be adjusted, length, elevation or azimuth. [:(]

Perhaps I could try getting my neighbour to adjust his antennae slightly, he lives in a very small house so I doubt he would need high gain, I'll give that a try.

I still think it's lousy of Ellies not to at least warn you before you buy these that this could be a problem.

I learned the hard way, buying cheap rc toys for the kids. Solved the problem by telling them to play at least 10 meters apart or different sides of the house. Nice side effect from this is very little fighting LOL

LOL, does make sence, doesn't it. [:)]

I wish Ellies would have gone to just a little bit more trouble, the extenders certainly weren't cheap, so you can imagine how ticked I am at them right now.

Interestingly enough, my neighbour and I both use Wi-Fi networks for laptops in the house and we both have DECT chordless phones. Neither of these have ever given us any trouble. Sure, the Wi-Fi stuff isn't strictly ICASA approved, but the DECT phones are, very much so.

My neighbour's Panasonic phone gives him nothing less than 45 RF channels to work with. My Siemens phones give me a choice of 60 channels. My phones are crystal clear for about 400 meters, walls, glass, etc, is no problem, they remain usable, all though scratchy, up to about 800 meters. Obviously, the signal must be quite strong to be able to deliver that kind of performance.

Yes dorris, these phones ARE ICASA approved, I have the gold hologram stickers on both phones and base stations to prove it.

If ICASA didn't mind allowing Siemens to use a huge frequency band with quite a strong transmitter, I really can't see how they would force Ellies to use one single frequency on a device that uses Amplitude Shift Keying, a weak signalling technology with a maximum possible line of sight propagation of 75 meters at the 2mW transmission strength the units are rated for.

All I have to say to the above is.. just WAIT till you've had to deal with Icasa. You have NO idea the idiotic rules and regulations they have. For pete sake.. these are the guys who dealt up the WiMax Spectrum.........

If setup correctly it works well. We use Ellies remote blasters in our house and flat. Our neighbors also use Ellies. After I have setup theirs there were no problems. Read the installation procedure on the box.

The Wizard remote extenders use digital codes to communicate because the frequency range available is obviously limited. The chances of two units using the same code is pretty slim but obviously going to happen from time to time.

What gets me is that it actually says on the packaging that they will not cross signals with other devices yet you claim that there is no warning. Slightly odd.

Perhaps you should take the units back to where you bought them and explain the situation. Try another pair, then come back and let us know if your rant was justified.

Hmmm. Right. lol. I didn't read the date on the OP. I just saw the thread near the top of the page.

I live in a townhouse complex, always had channel wars with someone who lived houses away!! He is over 50m away.

Just return it and get another brand?

I have the Ellies remote AV sender - it has a frequency button - currently running two in the same house.

Old post yes I know, but I have a set of Ellies Remote Blasters that have worked fine for years but in recent months somebody in our area is transmitting some signal that interferes with the remote blaster receiver unit. This interference causes the red light on the receiver's IR window to flash on and off constantly. It does not change channels or anything but it does affect the way our remotes work, you often have to push a button 3 times to get the command sent to the decoder, in between the other signals the Remote Blaster is constantly receiving. My solution eventually, and it works like a charm, was to take a piece of tin foil and fold it around the receiver unit of the Remote Blaster leaving only the Infrared window exposed, voila problem solved !!! Add that to the 101 uses for tin foil list.

And this, is the problem of poor regulation and over-use of the 433.92MHz ISM band... :rolleyes:
Try doing product development in that band, now that's hard! Sometimes R&D has to be conducted on public holidays here to avoid the interference issue.

Happens with us. It's the TV, not other signals. Put it behind the front of the screen. If you still have it flashing madly, place it on it's bum nose up feet forward, using antenna to balance. It should stop going mad and receive your remote's signals perfectly :)
