I have made these things. They're not hard to
duplicate but you do need a lathe and the
right taps for the cap threads. I may still
have a 3/8-32 tap around here somewhere.
I forget the thread size for the larger cap.
Didn't need to make that one so didn't
acquire the tap. The materials are not critical.
I cut the contact from brass rod, the cap from
aluminum rod and the insulator from delrin rod.
All that stuff was laying around and the tap was readily
available in Wichita so it wasn't a big time-buster
project.
I've lost the sketches I made for dimensions. You
would need to have access to manufactured parts
to acquire the dimensions. I'll have to check
with my buddy in K.C. to see if that part is
still flying on his Mooney.

| Subject: | Radio static when using 12 volt lighter power plug |
Obviously I have not grounded something properly, but I am at a loss.
I have two cigarette lighter plugs wired into my aircraft. They are to provide
power to my iPad on longer flights. I have noticed that whenever I have the iPad
plugged in I get some static when I receive a transmission. Otherwise the radio
is quiet. Not sure what to make of this. Why is it only on receiving? I would
think that if it was a ground issue, I would have the static all the time.
If there is nothing plugged into the power plug, I have no issues at all.
Any ideas as to what I should check first.

It is the iPad power adapter. Lot of discussion on this and other boards
about good and bad adapters. I have played with a couple and found one that
was better than the others......but my kids keep stealing and moving them.
I just live with it and only plug in the iPad when I need it.

When you receive a transmission, the radio opens the squelch which means
that it now also receives any weak signals that are present but too weak
to open the squelch by themselves.

Many thanks to everyone who's replied, fortunately I have access to the mate
rials and original parts as patterns so I think I'll have a go at matching t
he terminal parts. Pretty sure we'll have a suitable tap here somewhere.
Cheers,
John.

Good show! Send us some pix of the
finished product!
I got my 3/8-32 off eBay as I recall,
I think I paid more for it than this

I think I'm recalling that the larger
p-lead nut on the dual point
mag was 7/16-28
