Having problems today - never had anything like this. Using macros on a favorites menu to send channel numbers with .10 delay between numbers like 3 .10 delay, 8 .10delat, 0 .10 delay, enter. Hardware is an mx3000 and a 350 with remote rf about 100' max from remote unit.

50% of the time wrong numbers are transmitted. half the time it it the first digit missing. Other times its either a multiple repeat of a number anywhere in the string or a lost number in the middle. I have tried adjusting the ir and such to no avail. I have moved the ir emmiter - reduced/increased the brightness and also changed the repeat from 3 (default on mx 3000) to 2 and 5 with no differences.

Has anyone else every experienced this - RF reception is turned up all the way too.

Have you tried setting the MRF-350 to 0 to see if there is lot of rf interferance? The best fix is a MSC-400 that has all the fav macros inside it. then the MX-3000 has 1 code to send and the MSC-400 spitts out the macro.

What base station are you using?

I've seen the issue with the 250 & 300's but the 350 usually fixes the problem.
