Add Station Reading to Powershell prompt

Add Station Reading to Powershell prompt was created by Radslug
My station Radslug is fairly reliable but it uitilizes a modified Linksys NLU2 from around 2006 as a tiny single purpose Linux computer to read the count from a BroHogan Geiger Kit and send it to Radmon.org. Someday if it dies I'll swap out the Linksys for a R-Pi but Linksys quality was pretty good back then, so it may be a while.
Anyway, I don't check in on the station every day. So I miss when it gets hung up and needs a reboot. But I do use Powershell at least once a day at work. I realized I could grab the applicable lines from my station page on radmon.org & display them in my PS prompt. With a bit of formatting, the last update and current time line up and any discrepancy is visually obvious.
So, to save someone else wasting time formatting, here it is. Add to your
%HOMEPATH%\Documents\WindowsPowerShell\profile.ps1
- be sure to replace user=Radslug with your station handle.
If you use CMD more than Powershell, throw the line
Powershell exit &
into a .CMD and run from a DOS prompt.
It'll run & leave the powershell radmon text at the top of your window just above your first CMD prompt.

Also, in a perfectly Rube Goldberg way you can have that Powershell-exit CMD run every time you open a CMD prompt (thus displaying the station info at the top of a regular DOS shell) by creating the following key in the registry:
key: HKCU\SOFTWARE\Microsoft\Command Processor
value: AutoRun
type: REG_EXPAND_SZ
data: "path\scriptname.cmd"
(where path\scriptname.cmd match your "powershell exit &" CMD script)

Lines to add to %HOMEPATH%\Documents\WindowsPowerShell\profile.ps1

Ah this is great! How good would it be do see your radmon.org station count on your desktop background? For linux users translate into a conky script?

Probably a case where hxextract or python would be most useful but b/c of the page structure, I think it could even be done like this?
Quick-n-dirty but low resource, since it's static text & simple HTML. Still needs the refresh interval, etc:
Btw, the closing tag for H1 is coming across to my browser as h2 not h1.
ie,
<h1 class="serif">Radiation monitor for Radslug</h2>

Ok I've corrected the header class tags. h2 changed to h1 and i also found a missing / on /h3 closing tag
