Re: Band Plan

Steve -

Any agreement has to start with someone making a suggestion, and others "agreeing" with it. As more pile on, the agreement becomes more prevalent. And eventually (hopefully) it becomes pervasive.

(Note: a "gentleman's agreement" simply means there's no legal imperative, only that well-behaved gentlemen agree to follow it.)

The earliest published reference I can find is a May 1999 article in QST by Steve Ford (p41) that states that most of the PSK activity on 20m is between 14068 and 14080. One year later, Steve Ford published a second article (QST May 2000, p42) that says that 14070 was the "hot hangout." Of course, the 070 club was founded in mid-1999 and took its name from the frequency in use, so the common practice preceded the publications. (I picked up on the mode from that year 2000 article and a successor article the next month on Small Wonder Labs' PSK20, and got on the air in November 2000.)

I think the basic premise was that the various frequencies were within the generally-accepted band plans and weren't considered over-subscribed with other modes. In other words, 14070 (and 21070 and 18100 etc) were not already identified in other gentleman's agreements as being in use for other modes. Someone (could have been Peter Martinez, or Skip Teller, or Nick Fedoseev, or any of the other folks who were pioneering the mode or early software) had to suggest where on the dial to operate so the other few operators could find them. And that spread and became pervasive for over 15 years. Even the 070 club's archives document that, as we have had an "operating frequencies" page since about 2006 or so.

But I don't know is we'll ever be able to find out who was the first to suggest it or who the first "gentlemen" were.

Subject: [070Club] Band Plan

I am doing a little studying for my prep on Ham radio Now, I was looking at the band plan issue, and discovered that the band plan doesnt specifically mention where each mode is to be used in the bands. For example, 20M has 14.070 14.095 says RTTY, however IARU describes it as narrow band digital.

Then it discusses a "gentlemen's agreement for suggested frequencies and had 14.070 as PSK. Exactly who and when was this gentlemens agreement made?

Any background would be helpful.
