The radio kits from HF Signals are quite popular because they are:
- hackable in both hardware and software;
- well supported;
- work well considering they are inexpensive and hackable.
My radio kit arrived in September but I did not really have time to put the radio together, and had not decided on a case. I finally settled on a case from Amateur Radio Kits World-Wide, the colour is very nostalgic of my days as a signalman.
Universal Case Siemens Grey II & Accessories
|It comes with some useful parts not included with the BITX40|
The first thing I did was test fit the boards and parts into the case. Doing this while reading the wire up instructions gives you a better idea of how the wires traverse the case and a chance to consider various options. I learned three things while doing this.
First, the BIT40 diagram is a bit confusing because it shows the Raduino board from the side facing the front of the case, rather than the side you would be looking at while running the wires. The text instructions are better, but again from a point of view I would not have chosen. But this is not a huge problem.
Second, I had to ream out some of the mounting hols to get them large enough to mount the parts. Again not a huge problem, nor unexpected since the case is powder coated, but one you should be prepared to deal with.
Third, the voltage regulator on the Raduino protrudes past the left side of this style of case. Again easily dealt with by carefully folding the regulator the other way.
