Hi Pete and Hans,<br>
<br>
I am designing an amplifier for SDR1000/HPSDR and tried to get data<br>
(mechanical dimensions) for the transformers from Communication Concepts.<br>
What I found on the internet are not readable drawings and I did not receive<br>
an answer to my email inquiry from Communication Concepts.<br>
<br>
Can you or someone else give me a hint where I can get readable drawings for<br>
RF600, RF800, ...?<br>
<br>
73, Gerd<br>

On the contrary, they're very interesting although I must admit my German<br>
(the little bit I remember from High School) is not up to the task! I plan<br>
to follow up the references to Communications Concepts hardware. I'm sure<br>
I'll have some questions when I've had a chance to absorb some of this<br>
information. Thanks very much for sending them.<br>
