Just ordered a MTR qrp rig puts out only 3 W. Using LNR EndFed 40 M and active on aprox 7.050 and around 7.114 . Is their any way to judge if I would be better office using a tuner and getting the SWR to show 0 on the meter or should I trim the endfed to one freq and live with a modest SWR on the others. Any tips on trimming endfeds. I've trimmed my dipole but does a endfed have special considerations? Thanks for any input.
