TopBand: FT1000D Aux RX input

Hi Ken....this is also true of MOST all modern transceivers...Kenwood,  
Icom , Yeasu.....check ou this Web Page for a quick answer to keeping 
your Rig happy..."Front End Saver"....I killed the front end in my 
IC-765 twice before we figured out why!!

KD9SV designed them......at MY request after the above killing of my 
Icom
