PUXING PX-888 MANUAL PDF

The of plastic at the bottom looks like it could crack easily. Handle with care. Mine came in green, and it is a famous shade of green. Remember the IC-2E, and a few other models from Icom? Yep, that type of green.

Well, no it has a pinhole. But way too small to even work well so it may as well be blocked entirely. So, I drilled a hole the actual size of the mic. To do this you need to take the radio out of the cover. NOT an easy task especially for those who never fiddled with the inside of electronic devices or have special tools like small electronics screwdrivers and snap ring or castle nut pliers.

Here is what you do: 1. First, remove the battery. Then unscrew the aerial and pull off the rotary knobs. Then you use a crown nut tool or snap ring pliers to spin off the castellated nuts. Then use a flat head screwdriver on the bottom of the battery area to unclip the plastic case from the chassis. When you unclip the chassis you see it will be attached to the display board by a data cable.

Remove the two screws holding the display board. Remove the display board from the plastic case by gently prying away the case from the board at the bottom then the sides.

When you remove the board you will see the well in the plastic case for the mic. Drill a hole through the well from the inside. Blow out all debris and reassemble.

Reassembly is much more difficult because getting the display board back into the correct position is a pain. Of course an easier solution to the muffled mic problem would be to just use an external mic with your ear bud or get a throat mic. At the top of a very long metal pole mast is ideal.

The copper J-pole can be attached to the mast using a three hose clamps. Choke A choke is not necessary but is recommended for greater antenna effciency.

It bascially prevents reflected RF from coming back down the cable and keeps it radiating from the antenna as it should be. Make sure the windings are tight against each other and parallel. Can be secure with zip ties. Make sure the beginning of your choke is as close to the antenna feedpoint as possibe. Weatherproofing the cable to antenna connection This is important. Normally I quadruple seal my connection.

I wrap silicon stretch tape first followed by heat shrink tubing followed by tightly wound electrical tape followed by black dielectric silicone goop at the edges. J-pole showing SO connector Do a more thorough sealing job than shown here. The following are useful links to purchase the items needed to build a J-pole or purchase a ready built one and well as cable, connections and other antennas.
