No more listing of the year of records. Is there any site that has information they used to have?

Not sure about that, but I have been using the Metar archive page at Iowa State lately to solve my issue

https://mesonet.agron.iastate.edu/request/download.phtml

Back in June or July they changed the pages for airport stations, no more historical Metars that I can see (only a table of decoded data). Pressure is rounded to a tenth of an inch in the observation section https://www.wunderground.com/history/daily/KCVG/date/2018-5-10?reqdb.zip=&reqdb.magic=&reqdb.wmo=

For reference, that's the first NWS radar completely destroyed since Andrew took out the Miami one. A downburst did crumple the radome of KDRT back in 2001, but the internal components were not exposed.

I also found this one from the Reno radar back in 2008:

Radome was smashed, then a few days later another high wind event finished the job.

One of the tornadoes in Indiana came from a storm that was embedded in moderate rain (Holton EF-3). It didn't have a long life (compared to the other supercells) but it was deadly.

I was away from my computer for about an hour that afternoon (1:30-2:30 or so) and remember seeing how much had changed on the radar in that span of time (the lead supercell in southern Indiana had developed and was producing tornadoes).

That's the most impressive radar display I've seen for this area since the WSR-88Ds were installed in the 90s.

AVSET is supposed to reduce volume scan time, but I'm not sure of it's status.

From the AMS Radar Conference paper listed there:

"The basic premise of AVSET is to terminate the current volume scan after the radar has scanned all of the elevations with operationally important returns. In other words, once the data collection elevation overshoots the significant radar returns, the volume scan is terminated because there is no operational benefit realized by continuing the execution of the current volume scan, and a new volume scan is begun. The net effect of AVSET is to shorten the elapsed time between data collection on low elevation angles during periods when no significant data are available on the higher elevation tilts."
