I am using an MX-3000 with 2 MRF 300's. I am having a problem with the delay or no response from the second MRF. I have the first one connected with the RFX-150 and the second one connected with the stereo connector to the first one. When I am using the second receiver I get a delay or 2 out of 4 times no response. I am getting no RF interference and when I use the first receiver I have no problems. If I connect the second receiver with its own RFX-150 instead of daisy chaining it with the first one I have no problems. I have tried everything. If anybody has any suggestions please let me know. Thank you.

How old are the MRF-300s you're using? The first ones that came out last year had problems with daisy chaining. It should be fine with a recent model though. In any event, I would give URC a call and see if they can identify its age by the serial number.

I bought them both in the last 3 months. How do you tell what version they are? Thanks.

Here's the thread about the chained units failing but the second unit would not work at all. Did you try switching the position in the chain? If that doesn't work, I would call URC and get replacements.

The unit does work just not perfect. It works but it is either delayed or works 2 of 4 times.
