Good little pre amp, spoilt by poor assembly instructions Time Owned: 0 to 3 months.
I knocked one of these up to help my FM1000 on 4m and whist it works OK, improving S/N mainly, don't expect it to magically pull signals from out of the noise.
I was surprised that the PCB in the kit came without a solder resist or silk screen and that there were a number of errors with the associated kit list and assembly instructions. Also many of the component labels on the layout diagram were eligible due to the poor quality of the photocopied instructions. Not what I would expect from a company specifically selling this in a kit form.
More concerning was the very dismissive attitude of Spectrum Communications when I pointed these issues out to them in an attempt to assist them.
Not really recommended.
