I have a Alpha 99 with a rather strange problem in that on 15 meters only after tuning up it will trip off or fault as soon as it is key on RTTY, SSB or CW. It will not reset and can't use it on 15 meters. Other bands operation is normal and no problems this happens with both my ICOM 761 and 756. Anybody out there with a Alpha 99 have a problem like this ? 73 Gary
