1 Million Watts of RF - how the FM Supertower works

As the son of a radio engineer, I've seen my share of radio towers. From small, rural AM and FM towers to urban 'constellation' towers serving dozens or even hundreds of services, there's a lot more than meets the eye.

My Dad and I visited the so-called 'FM Supertower' in St. Louis, MO twice now, to explore the tower and the supporting infrastructure below. Both of these visits are documented on our Geerling Engineering YouTube channel:

ASUSTOR Lockerstor 4RS Review - 1U 4-drive NAS

Over on the Geerling Engineering YouTube channel, my Dad and I just posted a video where we installed the ASUSTOR Lockerstor 4RS - AS6504RS at his radio station, to increase their raw network storage capacity from 4 to 16 TB:

In the video, we focused on the installation, though I highlighted the unit's top-line features at the beginning.

In this blog post, I'll quickly recap the main features, then give more impressions of the unit from our experience setting it up, and my Dad's use of it at the station since we recorded the video.

BliKVM - a PiKVM (KVM over IP) box based on the Compute Module 4

I received a couple BliKVM units recently, and since I don't have as much of a need (my only 'remote' PC is about 2' away from my desk...), I brought them to my Dad's radio station, and we set it up in their main on-air PC so operators could access the PC and fix problems at home, instead of driving in!

Check out our video on this board on the new Geerling Engineering YouTube channel:

You can buy the BliKVM on AliExpress, and try your luck finding a CM4 to use in it!
