[TenTec] ORION - RF output is not stable

[I2DMI]

Hi,

when transmitting a continuous "mark" in FSK mode,  the RF output power
level of my new Orion is not stable.  (Same in CW with a long dash)

The meter shows, each 4 seconds (+/-), a short dip. (auto-oscillation or
software cycle?)

 

Also the CURRENT  absorption  is not stable and continues oscillating  at 1
second frequency. 

Sometimes I can see a double dip.

I tried different POWER SUPPLY but no change!

 

Any idea, please ? 

Thank you
