Instaed, let's just strp an external 2.2K. It will be beafy enough to provide reliable operation. - f Sent from BlackBerry® on Airtel -----Original Message----- From: Mark G0MGX <mark.g0mgx@xxxxxxxxx> Sender: minima-bounce@xxxxxxxxxxxxx Date: Fri, 28 Feb 2014 07:29:59 To: <minima@xxxxxxxxxxxxx> Reply-To: minima@xxxxxxxxxxxxx Subject: [minima] Re: Stuck in Transmit That's not a pull-up that's a pull-down. The PTT switch will pull the line to ground, I can't find the post but I think we said you needed to pull high normally and then use the PTT switch to pull low when pressed. When in RX the line should be HIGH so if you have put a 10K to ground that will pull it LOW. Your 10K needs to be from pin 5 to the 5V line.
