FT-2000 Headphone Audio Level

[W0BKR]

I have an FT-2000 and the headphone audio level is really low level audio, even all the way up, main VFO, where the sub-VFO (analog) is much louder.
Is there a mod the FT-2000 main vfo audio level out (headphone jack) does anyone know of? Sucks, for a radio like this, the audio level is extremely low level as compared to much cheaper radios....

I have had 3 FT-2000's and all had full volume using a Heil Pro Set Plus headset what are you using?

Proset 4, Koss Pro4/AA, and it is set up (menu) to do dual watch....doesn't matter...sub vfo audio is louder then main vfo via headphone jack front panel...
speaker volume is okay, but headphones, just too low..even using a headphone amp in line to the headphone jack...
