Poor mans spectrum analyzer #ubitx

Nigel G4ZAL

I have no sophisticated bench test gear so I used my hackRF and the free Spectrum Analyzer software to 'look' at what my uBitx was transmitting whilst on FT8 on 7.074MHz and the result is quite disappointing although not unexpected.
uBitx was on an EFHW for 40M and the hackRF was on a short whip antenna.

I have some Axicom relays and shielded SMD inductors for L5/7 and will compare results after swapping out the bits and see if I can 'clean up my act' !
