mx 780 and mrf 260 nothing but interference for sammy plasma b860, verizon cisco. first urc from rti, simple rf for stb and ir fot tv vol/mute. tv works fine, rf none, ir sometimes biut works on ll 3 other boxes in ir of the house. took a basement stb to my masbrm closet and of course no ir??

swapped boxes, used this remote on other boxes, but in this room w no lights and door shut pitch dark i get nothing. OEM works fine even in the dark.......so i learned thise codes into ch up and down and still dont work


what can interfere w rf and ir in a closet w no windows??

HDMI cables (cheap) can cause RF issues.

It's recommended to keep the base station away from the bluray players and hdmi cables. Apparently the 260 station will see that activity as interference and you'll have issues. It's also been mentioned that adding a ferrite core on the antenna can help with interference issues.

Ditch the MRF-260.  

Tell us us reason why you move to URC from RTI?
Should have stick with RTI...

Many have said that the MRF260 has horrible RF problems. Just recently it seems to have come to light that these problems might just be one more thing we have to blame on HDMI.  Okay, it's not the HDMI standard itself, but the standard should have included cable shielding requirements.  Do HDMI cables have to meet Part 15 requirements?  Where are the Part 15 labels?

Okay, so the MRF260 doesn't have RF problems; those problems are caused by poor HDMI shielding. The MRF350 does not suffer from those problems in similar circumstances... therefore, in the universe (in a world...) in which we use these components, namely near HDMI cables, the MRF260 has RF problems.  Reserve the 260 for your fully analog systems.

There are required to have sheilding (HDMi spec), however as with any product there is a lot of sub standard product coming out of the far east that does not meet the required spec.

Good answer.

Use an MRF350 and move the antenna until it doesn't have interference. I have actually put the antenna in another room to avoid interference.

so a 350 would solve this? going to pick one up

im trying urc bc of the 780......inexpensive solution. rti cant touch the price

i cant even say its interference. some code sets work some dont intermittently

AND......now that i think about the previous comments......i don thave any hdmis running near or next to any emitter cables? spent all day w kieth from tech and now i got the code set 043 that ive tried 9 times working...........duhhhhhhhh i dont know hope it works for atleast a week so i can get paid

I have tried this and it works. Take one of those magnets that you get to put around power cords for TV's and drop it over the antenna. I know it sounds kooky but we have don't this several times and the intermittent problems went away.

What out for "cheap" blurays........ One of the cost saving measures was to remove shielding from the power supplies causing rf interference.

I have had plenty of rf problems with the mrf 350. Removing the antenna all together has resolved most of my problems, followed by switching to Rti.

I don't understand how so many seem to have issues with URC. Yes the MRF260 has issues with rf interference it seems. As such, I only sell MRF350's or MRX1's. I locate the antennas as far away and as low as possible, typically in a basement or crawl space below if possible. I have had zero RF issues with URC products in literally years. One MRF350 with the RFX250 located away from equipment typically gives me full coverage in 5000+ sq ft houses.

Are there code set issues? Yeah. However if you use the line, you learn how to circumvent those issues and deliver a solid, perfectly working control system. RTI is not perfect either. We just added a Oppo bdp to a system and both the master and mega list had codes listed, none of which work. Learning codes proved the issue was indeed with the code set. We ended up importing the codes from a spreadsheet listed on Oppos site.

Sorry to rant on a bit, I just don't understand why I have nothing but great experiences with URC, over a large amount of time to actually mean something (~8 years with at least hundreds in the field) without any real issues. Have I just been lucky?
