I'm trying to check the Bias on the driver and final on my DX949.
I have the service manual from CB Tricks.
It states
BIAS Current:
Set radio to CH 20
USB TX mode.
MOD off.
Step 1
Connect current meter to TP7(+) and TP9(-)
VR12 50 mA
Step 2
Connect current meter to TP7(+) and TP8(-)
VR10 100 mA
I'm assuming the mirror board is removed prior to testing. Which I have done.
When I probe locations on step 1. I see 36.3 mA
When I probe locations on step 2. I see 36.3 mA.
I have my multimeter in the mA setting.
What am I doing wrong?
This is a new radio. Everything appears to be working good otherwise.
I'm assuming the service manual is showing correct information?
