The Watson PSU is a bit large really, but was purchased for a bit of future-proofing (and because I got a good deal when thrown in with the FT-950). It has an annoying habit of switching on its very noisy cooling fan when even a small current is drawn on receive. Perhaps when the PSU is a bit older I will modify it to correct this or install a quieter fan. The PSU has a rotary control that allows the user to change the frequency at which its internal switch-mode circuits work - this helps to reduce QRM especially on the lower bands (80m and 160m). In practice, I found this adjustment to be an annoyance (it is enough work to operate the rig without having to also operate the PSU!). So for now, I have resorted to a car battery as a PSU. This is recharged via a solar-panel during the daytime whilst I'm at work. I can keep a check on the voltage of the car battery from the FT-950 which has a voltmeter feature. A longer-term solution might be to locate the PSU further from the rig and to homebrew some hefty filtering to reduce its QRM to more manageable levels.
