Good, old days with tubes in TX and VFO running on lower frequencies generating less wideband noise.

I tried years ago to fix FT-1000D for VHF transverter but found wideband TX noise being only -80 dBc.

Poor TX IMD due to 13,8 V PSU together with TX WB noise are worst offenders in these SDR days.

73 de Mario, S56A

P.S.  We used vertical dipole far away from Yagi's tower at OI2HQ on 15 m CW in 2002.  TU again Jari & Jari!
