Hi, I have an Home Theatre set up for use with my old MX-3000 remote, using the MRF-250 RF base station for my hidden equipment. I am looking at getting an MX-890 hard button remote, and I am wondering whether this will work with the old MRF-250 base station?

Yes.

It will but with possible slightly more limited range and interference succeptibility. Since it's your personal setup I say go for it and see if it's passable in its current environment. You might be surprised.

Yes if you are using an emitter . If you are using a ir in on the back then no.

Good luck getting a 250 to work. Try removing the antenna. But even that is a long shot.

Hi, my 250 works perfectly with my MX-3000 (and it has done so in at least 5 or 6 different homes I have lived in, sometime with the antenna, sometimes without). My question now was only if the MX-890 would work with the 250. Unless the RF transmitter in the 890 is weaker than the 3000, then I should be OK?

You should be fine. I did a 990 with the old base station just this week. I was ready to swap it out, but the new remote was working fine with the old base station, so I left it.

There are plenty of bad vibes for the 250 and 260 base stations here. I think it can be accurately said that it depends on the installation and the interference in your particular area. In certain metropolitan areas and in certain installations, there is just more interference, and the 350 base station is the solution. In my particular area I have never had unresolvable issues with the 250 and 260.

You should be fine.

The problems with the 250 and 260 have to do with too much RF sensitivity. Other devices that use the same frequencies can block the intended transmissions. In the US, these might work great in rural settings but not work at all in areas of dense population.

I see you're in Oslo, which adds a nice twist to your situation. Approved RF frequencies vary from nation to nation, and there's every possibility that there simply are no devices on the same frequency as your remotes. In general you can expect that if your base station is working on one URC remote, it will work on others.

Of course, if you have doubts right out of the box, I hope you have confirmation from URC that this remote model is supposed to work with that base station.

Don't forget that some of the URC products including the MX-890 & MRF units are also available in a different frequency (433 instead of 418) and are differentiated with the "i" on the end of the part number.

I've never used the 433MHz devices so don't really if they solve any problems, but the manual does state that you need to match the remote with the base station.

Christopher - If you do buy the MX-890 make sure to check the model number on your MRF-250 to ensure that you purchase the correct remote.

thanks for all your advice! found an mrf350 so I should be ok either way. not going for the i solution. 🤓

Hi, what does this mean? I am using an MRF-250 with my MX-3000 and everything works perfectly, however when using my MX-900 the MRF-250 appears to respond to the the RF signal whenever I push a button on the remote (it lights up), but the cable box does not respond. (The cable box does respond to the IR command fro the MX-900 to the IR code should be correct)

There is no emitter on the cable box, I use the IR blaster for this (and this works fine with the MX-3000). Could the MX-990 or CCP somehow refuse to trigger the blaster, even when receiving an RF signal? Could that be the reson for the different behaviour?

Confused Chris

Seems to be working now. Strange, but it seems the signal was too strong. Don't see how that can be, since the signal comes from the MRF-250, nit the remote, but no problem from the MX-3000, only from the MX-900...

Some equipment like denon avr's have a Ir in on the back. Which u would use a mono 3.5 cable. The 250 was notorious for not working with those.

The 250 is a turd. Interference up the ying yang and 2.5mm emitter ports. Pretty much the only RF base on earth with 2.5mm emitter ports.

??? There were lots of cheap RF base stations that used 2.5mm instead of the standard 3.5mm.
Old Harmony hubs
Old OneForAll hubs
Old IR Pyramid repeaters
etc...

Agree the MRF-250 was a turd. Never had an RF base station give me so many problems as those old POS.
