Re: Ubitx V5 Low audio and No SSB #v5 #ubitx-help

 

Karan

Are you using the microphone cartridge that came with your uBITX V-5?
Several people have tried to use other microphones and experienced low?
audio level (low SSB output).? Some resolved the problem by enlarging?
the hole in the microphone housing to allow more audio to reach the?
electret cartridge. ?

Your 7.8 volts bias to the microphone seems about right. ?

Recently I assembled ubitx V5 in? cabinet after a year long wait in my shack.
Ubitx V5, CEC v1.2 firmware Nextion display, modified bafeong mic.

Receiver working nice but with low audio like in V4.
During just pressing PTT, ubitx consuming about 1.2 amps at 12v, but it is not varied with sound in mic. Loud ' hhhelloooo' do not vary current consumed.

Also noted? during? just? pressing PTT, my swr/power meter displaying stable power output of 3 watts.?
I checked mic bias voltage, which is 7.8 volt.

Help me to identify root cause of these issues.
