Re: QCX-mini update


Edge mount would be quite alright, though the edge mount SMA connectors I have used were designed for slightly thinner microwave boards and did not fit standard FR4.

I also notice that you managed to match the dimensions of the MTR3b almost down to the millimetre :)

Good point, I forgot that. Thanks for fhe reminder. I must see if I can put
them in. Edge mount? How can that work... the edge is up against the
enclosure wall.

No alternate pads for an SMA connector?

Hi all

I am excited to provide an update on the QCX-mini project

Again to stress: QCX-mini has the same schematic (almost), firmware,
operation and performance as QCX and QCX+. It is just a different physical
manifestation. This is not a major R&D effort. It is a pleasant breather.
The tasks are limited to mechanical re-engineering and some
re-documentation later. So please don't all start yelling at me about what
I ought to be spending my time and energy on instead.

To summarize: I laid out a PCB. Two in fact (it's a sandwich). And got
made. I have ordered two sets of components and one set arrived yesterday;
the other (the bulk of the R and C, SMD parts from Farnell UK) will arrive
in about 1 week. I designed an enclosure and made technical drawings, and
my usual enclosure factory has produced a prototype to my specification,
which is in the post and will likely get here in about 2 weeks from now.

So far everything fits together very well and at this stage I do not
anticipate any major roadblocks.

It's a really beautiful little radio! I am looking forward to hauling
myself to a nearby mountain to try it out.
