Ongoing issues:
- UPS runtime curtailed.
- As noted in the 21-22 September, 2024 entry we discovered that
our 28 month old lead-acid batteries for the UPS had a run time of only
about two minutes. We have ordered LiFePO4 replacements and will
install them as soon as our schedules permit once they arrive.
- Power line noise noted on some bands on WebSDR #5.
- As WebSDR #5's antenna is a northwest-pointing beam which is
aimed at these power lines, emissions of noise from these lines will be
noticed there, first. We have - for years - been working with the
power company to mitigate this noise issues but it is a slow process on
this very old (circa 1960s) power line hardware.
- Known interference source on site - the new UPS.
- We observed with the replacement of the UPS that a "new"
interference source appeared. This usually takes the form of an
intermittent noise - most clearly seen in the low frequencies (<25 kHz) on KiwiSDRs 1-3.
- During the 21-22 September, 2024 site visit a mains line filter was added which seems to have quashed HF noise, although it (expectedly) had only a slight effect on the energy <100 kHz.
There are no known, ongoing issues with other receivers at this time.
