Tom, Dave, et al - one reply to your query. I have used ASTRON for years,
and with LF equipment as well and have never noticed a problem with
switching supplies. I think that ICOM's supply that I bought with my (by
now) old IC730 and no problem altho I don't know if ICOM took any special
trouble to make it noise-free.
I have not done any 'sniffing', simply because I have never sensed the need
for it.
