1.6ms is pretty good performance for an LF radio clock. If you want to do
better than that, you'll have to consider GPS. I have a professional DCF77
receiver that right now is +2.6ms.
The radiation from a monitor is a good way to swamp the radio signal, so,
depending on the proximity of monitor and antenna, I would expect you to get
more reliable radio reception when you are not working.
