Reviewing the FT450 docs and scrounging around online, I think the SWR readings for the 40/15 and 20 meter elements are good, and if not good, at least acceptable. I tried to make contact another station on 20m yesterday, but the band was fading fast and he lost me in the noise. Band conditions seem to be pretty good in the morning and mid-day hours, which are unfortunately when I also have to work. If I can pull it off without crashing through the ceiling again (since the most recent sheetrock repair is actually still drying as a type this), I’ll carefully add elements for 10m as well. That should about do it for the time being. Then it’s just a matter of, you know, actually making some contacts.
I had the radio connected to an old and pretty flaky Macbook for rig control. It worked, but was sort of meh. Probably a little more interesting when running stuff like fldigi, so a Signalink is probably in my future.
