Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
The first suggested option was less than $4 which to me is the better way to go UNLESS the flange is hobgobbled and not plated professionally. Seems there is a price to everything, though, an

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
The hole in the SO-234 flange has to be reamed/drilled out unless you go to small hardware. I have also used screws that were forced into the hole so no nut was necessary. Many connectors have as many

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
The mounting flange on those is smaller than a SO239, with closer hole spacing, so the existing mounting holes for the SO239 must be elongated into radial slots in order to mount the BNC. -- Rick

Hi Rick, I drill thin sheet metal clamped to a wooden block that is mounted in a vise. I am not going to slice a finger(s) open. The times I used the nibbler and files to make the D hole there was no

I was fooled with a plug once that is the same used on the Baofeng microphone until I realized I was not pushing the mic plug in all the way. Quick fix. Bob ¡ª KK5R

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
At $3.92, it looks like a good deal to me. Have to have a hole in the receiving chassis/panel same size as for an SO-239 but if the mounting flange is to be located behind the mounting surface, a hole

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
If you chose to go the drill route, I highly recommend a 'step drill' for thin sheet metal. Regular twist drills have a nasty tendency to grab and send the maretial spinning. If your hands survive the

Hi, I have used some of the chassis mount BNCs as shown here. I have used plan A and installed 'hole mount' BNCs with the lockwasher and tightened them enough to hold. I have also used plan B and

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
You can also form a kind of D-shaped hole by using a center punch and mashing out the edge of the hole with a series of three holes or so at one point, squeezing out the hole to fit the socket. Or,

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
Harbor Freight used to sell a Deep Throat Metal Punch which would make an easy job of this. I have one but they no longer offer this hand tool. It can be done with a drill press but safety precautions

Re: plugging mic in causes the ubitx V6 to go into transmit mode
So, start with the basics. Read the voltage on the push to talk pin of the jack, and see what happens to it when you plug that mic in. If it goes to zero, you are shorting it out somehow. Proceed
