[BULK] - [Amps] Tempo Henry 2002 / FT-736R

[Steve Katz]

Based on that response, I'd say:

-Disable the RF keying circuit in the Mirage (really easy to do, just life
the sense lead)

-Use "hard keying" for the Mirage, as well as for the 2002.  

Problem should go away.  If it doesn't, sounds like the Mirage is
oscillating under no-load conditions.
