Using svxlink to transmit, when it unkeys, the squelch tail that comes back triggers the GPIO briefly, which opens the squelch.  This isn't a huge deal during an actual QSO, but it means ANY transmission by svxlink will result in a brief squelch open/close:\r\n```\r\nMon Apr 20 22:30:00 2015: SimplexLogic: Sending short identification...\r\nMon Apr 20 22:30:00 2015: Tx1: Turning the transmitter ON\r\nMon Apr 20 22:30:05 2015: Tx1: Turning the transmitter OFF\r\nMon Apr 20 22:30:05 2015: Rx1: The squelch is OPEN (4.8478)\r\nMon Apr 20 22:30:06 2015: Rx1: The squelch is CLOSED (4.74761)\r\n```\r\n\r\nWhen I was using SQL_DET=VOX, this wasn't an issue, but I was having noise floor issues causing dropouts when people would pause to breath. Using SQL_DET=GPIO fixes that issue, but introduced the brief open on the received squelch tail.\r\n\r\nI've tried playing around with SQL_START_DELAY, but that doesn't seem to have any effect on GPIO squelch detection.  I've set it as high as 5000 and it doesn't behave any differently than setting it to 5, 50 or 500.\r\n\r\nFrom the mailing list discussion, it appears that SQL_START_DELAY with hardware squelch is not implemented.  I would like to see this added."},"comment":{"url":"https://api.github.com/repos/sm0svx/svxlink/issues/comments/148055438","html_url":"https://github.com/sm0svx/svxlink/issues/137#issuecomment-148055438","issue_url":"https://api.github.com/repos/sm0svx/svxlink/issues/137","id":148055438,"user":{"login":"granitepenguin","id":913430,"avatar_url":"https://avatars.githubusercontent.com/u/913430?v=3","gravatar_id":"","url":"https://api.github.com/users/granitepenguin","html_url":"https://github.com/granitepenguin","followers_url":"https://api.github.com/users/granitepenguin/followers","following_url":"https://api.github.com/users/granitepenguin/following{/other_user}","gists_url":"https://api.github.com/users/granitepenguin/gists{/gist_id}","starred_url":"https://api.github.com/users/granitepenguin/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/granitepenguin/subscriptions","organizations_url":"https://api.github.com/users/granitepenguin/orgs","repos_url":"https://api.github.com/users/granitepenguin/repos","events_url":"https://api.github.com/users/granitepenguin/events{/privacy}","received_events_url":"https://api.github.com/users/granitepenguin/received_events","type":"User","site_admin":false},"created_at":"2015-10-14T13:50:36Z","updated_at":"2015-10-14T13:50:36Z","body":"Sorry about that.
