VX-177 dis-assembly

humaxf1

Hi folks,

Any ideas on taking a Yaesu VX-177 apart? The TX audio is very low and has been documented on mods.dk and eham. Due to a "membrane" over the mic capsule, the audio is very low. A paper clip to pierce this membrane fixed one radio, but not on another.

So far, (according to mods.dk) I have:

Removed the on/off and dial knobs
Removed a retaining nut sourrounding the on/off and dial shafts
Removed 2 screws at the bottom of the radio in the battery tray

In theory, it should prise apart at this stage. The bottom comes apart to a point, but up top (knob/aerial/mic soc panel), there appears to be no lee-way. I don't want to force it too much if I'm missing a step.

Any help much appreciated. Thanks.

Scroll down near the bottom for instructions. Apparently, you "Seperate case halves by pulling down and out with the back half". Worth a shot :eek:

be careful if the 177 is water resistant and you remove or pierce the membrane you lose that capability

aye, good point.

I'm not too worried about that part really. If i was going to take it into the shower, I would have a sit"ye"ation

The nut around the antenna socket looks like a pain to get at for a good grip to unscrew. No doubt there is a special spanner out there to grip it in the two slots.

There have been a few complaints about this on forums. Surely Yaesu has copped this, but continue to install the membrane!

Yea read about it in radio user some time last year seems a big problem afaik I think they changed the spec maybe try a seperate mic if you feel uncomfortable opening it up.

I have "1" speaker mic, but 3x radios.

I'll just take my time.
