[Orion] Keying loop has glitch when using Rx Ant

I am using an Orion with Version 3.032 firmware to drive an Acom 1000
amplifier. I have just added a Pixel Technologies RF Pro-1B magnetic loop to
my station and connected the loop antenna to the Rx Ant RCA jack on the back
of the Orion. I am using a keying loop connection between the Orion and
Acom.

I have just noticed that when the RxAnt button is activated, there is an RF
power surge from the Orion's output when the Tune button is pressed the
second time (to end the tuning phase). This does not happen if the receive
antenna input is not being used (the RxAnt light is off). I have eliminated
the problem by reverting from a keying loop connection between the Orion and
Acom to the simpler connection consisting of connecting the Amp Key jack on
the Orion to the Key In jack on the Acom. Of course when I revert back to
the one wire connection between the Orion and the Acom, I have to turn off
the keying loop in the Orion's menu.

Has anyone else had this problem?
