Hi all! The last few jobs I've completed using an MX780 & MRF 350 combo and they appear to be consistant with two problems. All remotes & kits were purchased at different times and different suppliers. I notice the MX780's buttons are not always immediately responsive (on at least 6 remotes this year) and sometimes require a second press, doesn't matter if it's IR or RF. The MRF 350's are picking up more RF interference then I've ever seen. No jobs have the same gear, different cable & sat boxes, one had appleTV one didn't, AV Receivers different brands, Blu-ray different brands. Moving the antenna around, changing antenna connecting cables and still lots of interference rendering the control system super unreliable.Last one was so bad I had to install an IR Kit in place of the MRF350. This past year I switched over to the MX780's after using MX850 & MX350 for years with very few issues. Appreciate any thoughts/experiences you've had. Have a Rockin' Day
