I got my callsign last week and picked up an FT-70DR and a ZumSpot kit from Ham Radio Outlet. I'm unfortunately stuck where I can hear everyone in a room but no one can hear me. I'm not really sure what to do or try at this point. I started off in the PARROT room and am able to transmit out to that and receive my audio byte back. I have a BER between 0.9% and 1.5% and a clear signal, so I would assume my setup is capable. BUT, when I go to a more popular room, like America Link, it seems that no one can hear my calls. I know folks are listening - several other people pop in asking for signal checks and get prompt responses. When I ask the same way, no one ever responds. To my knowledge, I'm putting out calls the right way (saying things like "This is KC3NSE. Can I get a signal check? Am I coming in okay?"). I tried a few times over the course of the day with no luck. I don't know what I'm doing wrong. Anyone have any ideas?
