Are you using a new Serit tuner? You might want to check that your phase noise problems are not in the receiver first. Put a 10dB pad on the tuner input and see if it improves matters at 70 cm and 146.
Yes, I'm about to need a bezel. Flat to an Aluminium panel. Has anyone on the Forum got a successful 3D print design for this?

I am but I had 20dB on the input - I had thought of that but this time no, I don't think its the receiver. I suspect it is noise on the supply from the DC-DC converters. Easy to check. Less easy to fix!
For the panel - if these 7" screens work as well as the recent reports, it would seem a much better solution. In my view, any screen intended for the PI that doesn't have mounting options is a bad design. I spent about an hour cutting out a hole for the screen and fabricating some clamps - but any clamping system is likely to put stress on the LCD.
