K3 Test from Bavaria

[dj7mgq]

Hi Gang,

at <http://www.bavarian-contest-club.de/projects/K3.pdf> you can find  
Version 1.0 of our K3 test. Currently only in German, but I am working  
on a translation.

We plan on extending the report after the next important contests and  
further measurements. Also I will be adding a few comments about  
building the kit etc.

Interesting work Toby. I would be interested to know how the K3's receiver
behaves in terms of overall 3rd Order dynamic range (or Input IP3 and Noise
Figure plus composite LO phase noise) while the test tones are moved in
steps up the higher skirt regions and into the passband of a 8.215 MHz IF
filter's response, hopefully without activating the 'Hardware AGC'. I
appreciate that not all filters are born equal and that signal generators
produce phase noise. Will you be including such tests sometime in the
future?

Hallo Geoff,

I don't know yet. We have a whole list things which would be  
interesting to measure, but won't have to test everything. One item on  
our list is: What is the close in degradation with one of the wider  
filters, e.g. the 6kHz filter.

Also I would like to point out that while I provided the K3, Matthias  
& Ben have done most of the testing and writing up of the results.

Many thanks, and thanks to Matthias and Ben as well. I look forward to
seeing your results and hearing your K3 on 40m.
