[Elecraft] KAT100 Won't Tune When IC706 Also Turned On

[Gottlieb, Jonathan]

Any thoughts on this one:  Today I hooked up an antenna switch so I could run the K2/100 and the ICOM 706 and switch between them and use one or the other when I want to.  Both radios run off the same Astron SS-25 power supply.  When I have the 706 turned on and RX only, the KAT100 will not tune 40 or 80 meters.  If I turn off the 706, the KAT100 works perfectly.  It tunes all other bands with the 706 turned on. The 706 is only receiving so I wouldn't think it would be drawing enough current to effect the K2.   Any ideas on this gremlin?
