[Alinco] Display flicker once as PTT is released DR-03

[Anders Janis SM4RNA]

The radio is conected to SWR.meter and dummy load and 40A PS. I have 
tried two power cables.

I have measured the VCO voltage. At 29.00MHz it is suposed to be 6.0V 
plus/minus 0,1V. The voltage is 5.90V when the radio is cool and drops 
just below when the radio is warm. The flicker seem to get worse as the 
radio get warmer. If I transmit for 10 minutes it can flicker two, three 
times and sometimes even more.

I guess I should try to adjust the VCO voltage, but I could not find a 
suitable tool, just now.

Or any other ideas?
