history of VHF BandIII - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the 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.
