[TenTec] Orion 28 Mhz noise

[bob finger]

My Orion has decided to generate some noise on ten meters.  The receiver 
has frying hash at about 30 over 9, rendering the receiver useless.  
Other receivers in the shack have NO noise on ten unless the Orion is 
powered up....yes the noise generated by the Orion can be heard in other 
receivers.  Orion is dead quiet on 12 and below.  Anyone else ever 
experience this and found a cure before I trouble the good folks at 
TenTec with this one?  thanks.  73 bob de w9ge
