The subject of Nexrad radar "unknown mode" came up in a series of comment exchanges with dutchsinse. He mentions the subject in his blog post about Sandy:
Geoengineering Frankenstorm: Hurricane Sandy and the Air Force Weather Weapon System
Which times match up exactly with what events, he doesn't explain.
Dutch asked me what I know about "unknown mode" and he went into more detail of his version:
He's talking about the label "unknown mode" in a graphical representation of a text file that is a summary of the status of Nexrad Level - III data products issued for a given location. The rest is just gobbledygook he made up in his head.

Here's a portion of the text file the above graph fetches its data from:
Each row is a summary of Level - III data packages with a time stamp (ZTIME) of when the data were sent, a letter code for operational mode (OPMODE), and a numeric code for Volume Coverage Pattern (VCP). Not only do Level - III data packages include the actual radar data from each volume scan, the summary file also includes text messages such as routine radar status messages, notice of scheduled maintenance outages and general text messages. Some text messages do not have a code for operational mode (A, B or C) associated with them so the OPMODE field for those time stamps are blank and the VCP code is -999. The graph reads the blank OPMODE field as "unknown mode" for display on the status summary graph, color coded as a black line.
Here's the General Status Message graph for the same location and day. This graph depicts when routine radar status text messages were sent... the color coded unknown mode black line "times match up exactly" with corresponding time stamps that have blank OPMODE and -999 VCP fields in the associated status summary data file:
All Level - III summary graphs
So I basically described the above facts to dutch proving I know what "unknown mode" actually is. He replied with this:
No dutch, what's pathetic is the way you make up fantastical pseudo- science fiction stories to explain the pretty pictures and graphs you see without even bothering to learn about the underlying data those images and graphs are based on. Thanks dutch, once again you're on record demonstrating that you don't know WTF you're talking about.
If "unknown mode" were when a radar transmission pulse occurs, there would be hundreds of them per second. In the above data file and summary graph there are only 16 instances of "unknown mode" for an entire 24 hour period.
How does the radar work?

Hurricane Sandy — "frankenstorm" was pulsed by NEXRAD RADAR in "unknown mode" ….. times match up exactly:

Dutch asked me what I know about "unknown mode" and he went into more detail of his version:
tim.. please tell us everything you know about NEXRAD RADAR's "unknown mode". What does it "pulse" in... MHz wise eh?!
hmm.. ironic that MHz wise.. "nexrad unknown mode" is pulsing in the SAME region that it take for "corona CCN" building
hmm.. maybe you just don't WANT to connect the dots.
targeted NEXRAD RADAR is in the GHz Plasma mirror range
pulsed NEXRAD RADAR is in the MHz CCN generating range
what happens when you hit powdered metal with targeted microwaves? Plasma, heat, lightning

no tim.. unknown mode is what the RADAR goes "into" when a pulse occurs... not a text message...
just blank eh.. now you're on record as saying such..
and to think.. you actually think you're on top of it.. pathetic

How does the radar work?
NEXRAD (Next Generation Radar) obtains weather information (precipitation and wind) based upon returned energy. The radar emits a burst of energy (green). If the energy strikes an object (rain drop, bug, bird, etc), the energy is scattered in all directions (blue). A small fraction of that scattered energy is directed back toward the radar.
This reflected signal is then received by the radar during its listening period. Computers analyze the strength of the returned pulse, time it took to travel to the object and back, and phase shift of the pulse. This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second.
NEXRAD spends the vast amount of time "listening" for returning signals it sent. When the time of all the pulses each hour are totaled (the time the radar is actually transmitting), the radar is "on" for about 7 seconds each hour. The remaining 59 minutes and 53 seconds are spent listening for any returned signals.
