mcHF - Making A Start

 Ive spent some time recently on just feeling my way around the physical construction of this radio. Its a very compact unit, so it makes sense to take the time to really understand how it all goes together.

Im now in a position as to confidence to make a start. Since I have been learning the construction of the case, it made sense to install the loudspeaker first, since that requires the absolute least work! But even this was a learning experience, as it taught me that there are a few of the Japanned machine screws that are just that little bit longer, and seem to be intended for mounting the power components. 

Having watched several peoples videos, read as much of the .io group files and posts as I can, and found and joined a Facebook user group, Ive got a good idea how it all fits, and a number of pitfalls. For instance, it looks as though one of the holes in the RF screen will need widening to accommodate a tall capacitor. Theres a little trickiness as well in installing the ESD protection neon lamp, as its board holes are underneath the BNC connector!

So, later, I will install the neon, the BNC, and the various connectors and switches. With these in place I will be able to see better where and if the RF screen requires adjustments!
