Thanks Werk - I discovered the antenna on the Tx unit had fallen off its currently only a magnetic base - so I corrected that but unfortunately the RF efficiency dropped to 16%    There's a lot of things I can try to improve.

Before I start trying out these things I just want to confirm I understand the way to assess improvements. I assume the RF efficiency is a ratio of packets successfully received, versus total packets detected ?  and it needs to run for at least hour for the measure to be useful ?  Is it a rolling average - can you confirm over what time ? or do I need to reset the unit for each test.

Is there some sort of signal strength indicator - is that what the 3 dots on the front of the touchscreen are ? is it possible to get a signal strength from somewhere ?
