Re: Spurious Emission Measurement on stock uBitX

Thanks for reading.
No, I didn’t insert any LPF but only the simple pi-tuner was there btw uBitX and analyzer, because I thought pi-tuner might work as a kind of BPF.
There will be a possibility to suppress the spur emission if I add a LFP but what I observed was the spur of 28MHz with AT was OK but 21 MHz was not. So maybe I need some drastic solution, I suppose.
Here is a manual of TRIO AT-200 antenna tuner, if you are interested in it.
Yes, I’m planning to do like what you did. So I already got AA-30.ZERO antenna analyzer.
Thanks for your comments.
