Jeff: I watched a WinLink station knock four stations off of the air yesterday. I have dozens of screen-captures of waterfall displays, showing WinLink stations crashing up to five QSOs at once. It happens every day, and is easy to document.
You looked once, and didn't see anything. You can take it for granted that I know exactly what I am talking about and have no need to exaggerate. As a thought experiment, try going on QRZ.COM in the "Talk and Opinions" board and stating that you do not believe that WinLinkers ever crash other people's QSO's. Common sense should tell you that anybody transmitting ultra-wide digital hash on HF without listening first will of course end up causing interference, willful interference in WinLink's case since they refuse to run any busy-detection but if that doesn't convince you, go ahead and see what kind of reaction you get to your theory on QRZed. 73 DE Charles Brabham, N5PVL Prefer to use radio for your amateur radio communications? - Stop by at HamRadioNet.Org ! http://www.hamradionet.org ----- Original Message ----- From: Jeff Moore To: digitalradio@yahoogroups.com Sent: Thursday, October 29, 2009 9:54 AM Subject: Re: [digitalradio] Why would anyone Charles, I'm going to disagree with your statement: [see below] I just spent a day operating on all of the various pactor modes and we never heard any other qso's during that operational period get interfered with. Contrary to what your statement implies. The automated pactor stations don't initiate qso's, they respond to qso's initiated by live operators. It falls on THOSE operators to insure that they are not interfering with other qso's in progress, not the automated response stations. Unless I'm missing something here, none of the Winlink 2000 automated stations initiate transmissions, they only respond to requests.

How long do you think the FCC will allow this to continue before they clarify the PART97 regulations in this area? 73 DE Charles Brabham, N5PVL .
