RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

history of VHF BandIII - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including responses to the original posts.

Hi.

I have very basic and simple question.


I:ve frequently seen the description "VHF band III".

But I don't know of the origin of the description Why "III"? For what VHF band is classified to "III"...

If there is someone who know of this, please let me know.


Regards,
ZXH06616

As far as I recall, some time in the 1960s some dudes, probably at ITU-R divided the VHF and UHF TV Bands into sections, I thru V

Band I was 30 thru 87 MHz
Band II was 88 thru 108 MHz
Band III was 190 ish thru 230 or thereabouts
Band IV was 490 thru something
Band V was all the rest up to 800 MHz or so.

I would like to be more precise but as I was apprenticed to Michael Faraday, my memory is failing.
