Re: Changing out L5 & L7 in UBitX for Spur Fix

How big are the spurs at 12Mhz? Transmitting on 20m I could barely see that on my Softrock receiver (which grounds on TX) and a lot less than the fundamental, seems, I would say at least - 50db. The spur exists but seems to me quite low. Has anyone measured it against the fundamental with a reliable spectrum analyzer?

I ordered the kit from the ubitx.net link on spectral purity: https://ubitx.net/spectral-purity/

I am assuming that it will include the correct devices.

Thank-you for your checking!
