Forwarding path: KB3X VE3SNP VE3NUU VE3FJB VE3JF VE3IWJ I noticed that the KAM, when connected or trying to connect, will start to transmit on top of an other signal at times. This will happen when a received signal appears just before the the KAM wants to transmit. It is visible by looking at the mark/space display. After a quiet period a received signal will light up the bargraph display and the KAM will transmit on top of it. Looking at the circuit diagram, I noticed a 1 uF capacitor (c 29) in the carrier detect circuit. It seems to slow down the detect function more than desired. Changing the capacitor to .1 uF made the carrier detect work more the way I expect it to. It is easy to get at. Somewhere in the middle of the board. There is a layout in the manual. I didn't ask Kantronics about it. And I didn't notice any side effects. I also didn't try it in any of the other modes. Comment to ve3iwj @ ve3iwj. 73 Nand.
