Modifying Wouxun KG-XS20G+ Mic for increased PTT pull weight.


Question

Posted

I have big clumsy hands making it easy for me to accidently key the mic when grabbing for it.

To address this in the past I have modified mics with stiffer or additional PTT button springs, but with Wouxun KG-XS20G+ design I can't make that solution work.

Luckily, I think I found an alternative.

 

First of all here's the stock KG-XS20G+s MIC's PTT pull weight which comes in at about 11oz.

This first thing is to get a gromet of dimensions D=7/16", I.D. = 0.336", O.D. = 19/32" T = 0.049.  (Available in a Harbor Freight gromet assortment box)

Next, use a razor knife to CAREFULLY cut off one side of the gromet. The cut needs to be as clean, flat and flush with the gromet half's side as possible. Discard the other half.

Now, remove the four screws holding the two halfs of the mic body together and carefully separate the them taking care not to stress the mic's speaker wires.

Remove the PTT assembly and place the gromet half as shown in this pic. Note the flat side of the gromet half is facing the PTT button.

Re-install the PTT assembly taking care to keep the gromet half in place. Lastly reassemble the mic and secure it with it's 4 screws.

With the modification my mic's PTT pull weight now measures 1 lb. 10 oz.

CONCERNS - The addition of the gromet is putting additional lateral stress of the PTT button. Over time there is at least a possibility it may bend the button assembly back making PTT unreliable. The additional stress could also cold work the button's solder connections to the PCB. With these concerns in mind, I tested the modified mic by pushing the PTT button firmly 100 times with no ill effect. I also banged the mic as hard as I dare from different angles, but I was unable to displace the gromet half.
