Okay,I finally have the Kenwood TS2000 up and running.I can't hear my downlink.Running one antenna shouldn't have to do with it right?I worked half duplex and had about 3 contacts so now I have full duplex setup.I have the Amsat chart so I set up for those frequencies.For doppler shift on 440kc is it  +-15kc?I am running about 20watts so I should be okay,It's alot but it's also a vertical.I unlink the uplink  on my radio and listen and transmitt while moving the downlink-nothing?Any advice.Thanks alot for your help:)73Rich marzo7088@yahoo.com
