Re: trick to soldering in L5 and L7 or why did spurs on 80/40 get worse and 20/10 get better...
For 40/80 spurs you need to change the 3 filter relays to AXICOM.toggle quoted messageShow quoted text
L7/5 improves the higher bands in my experiments.
L5/7 should have equal effect on all bands as it is an IF stage and all bands will be same unless you are over driving
Power loss noted by me is minimal with yellow inductors, with other SMD inductors there was severe opwer loss.

Hi all, could use some pointers here on replacing L5/L7 on a V4 board. Not having a real spectrum scope, i am using the sdrplay with their spectrum scope software... Was using a RF sampler + 110db attn (HP 355d)
