Re: QMX+ Power Output


 

Some months ago when building my HB QMX I made some calculations and a lot of tests to the same problem. Maybe this could be helpful. There is also a statement by Hans.

with my FA-VA5
I used my VNWA (DG0SAQ) to measure the inductivties. When using my FA-VA5 I found higher values than with the VNWA. Checking the FA-VA5 using known high impedancies they were shown with significant deviation. So the inductivities may be also lower than shown.
The FA-VA5 was calibrated using good SOL elements. For impedancies not so far far away from 50 Ohm there was no problem.
