[Yaesu] FT-900 RFI

2002年1月24日 15:46:33 +0100 (CET)

Hello all Yaesu fans,
My FT-900 is very sensitive to RF feed back through the mic. When I use 
my Antenna coupler obviosly RF radiates "uncontrolled" sometimes... 
Connecting a mic to the connector on the front will then reslut in RF 
problems. If I disconnect the mic and transmit CW or PSK31 connected to 
the AFSK input connectors on the back panel the RFI is gone. I am 
currently unable to work SSB so I wonder if this is a common and well 
known problem for the FT-900 and most importantly does anybody know of 
a (simple) way of fixing it or seen it described somewhere?
