| Subject: | portable push to talk switch |
--> AeroElectric-List message posted by: Robert Dickson <robert@thenews-journal.com>
I bought a headset from Spruce not long ago and decided to invest an
additional $8.95 in their "economy" push to talk switch. You know, the
kind you plug in between the headset and jacks and gives you ptt
capability without hardwiring a switch into the stick. My pax stick is
removable so I didn't bother with wiring some sort of plug or even a
dash mounted ptt switch.
My problem with my el cheapo portable ptt is that when it's plugged in
it kills the intercom. The passenger can transmit and receive ok but we
can't communicate with each other. I've used these switches with no
such problems in other planes without a hard-wired passenger ptt
(notably a G33 bonanza).
The audio panel is a Garmin 340 that works great in every other respect.
Is this a problem with the cheap switch or is it something in the way
my stuff is wired? I don't need this capability very often but it's
nice to have when I need it. Anyone else have this problem or have an
idea what's going on?
TIA

Hi guys,
I'm building an RV-9A. When I needed a buss bar
between the main and starter relays, and to join a
row of circuit breaker or switches, I used a length
of thick wall, soft drawn, gas tubing made of copper.
I squeezed it flat and drilled the necessary holes.
The flat section is between 1/2" to 3/4" wide.

What's "common" for anyone else may have no bearing on what you
need/want to to do. Any of the architectures depicted will perform
with greater reliability than anything certified simply because you're
not saddled with less-than-the-best-by-decree hardware.

If I were building an airplane today, Z-13 with dual p-mags would
be my choice . . . the vast majority of OBAM aircraft being
constructed today have a close or close copy of a C-172 which is
what Van's sells and/or recommends in his kits. I've had at least
two builders put Z-14 in their RV-8's . . . and if they're reading
this and wish to join the conversation, I'm sure they can give
you persuasive monologs as to their reasoning for those choices.
I'm not trying to belittle anyone's offer to give you advice or
an opinion but at the end of the day, the electrical system can
be as personalized as your upholstery or paint job. If you bought
and read the book (in particular chapter 17) what are YOUR impressions
a system that meets your needs? If you have doubts, can you articulate
them? It's better that we offer guidance to re-enforce or refine
what's attractive to you than to give you a data dump on what everyone
else is doing.
Suppose you start with Z-13. Do you perceive any shortcomings?
Do you have any special-needs equipment? Do you have a FADEC or
EFIS system that wanders off into the woods if powered from
the engine cranking battery?

Received my GS-Air position and strobe light system, very impressive
set-up. The design and worksmanship appear impeccable. Giovanni at
GS-Air was very patient and thorough answering all my excessive
pre-purchase questions, and I received the system two business days
after ordering it. Jabiru is now installing the system in all their
new aircraft, and I can see why. Now I won't have to buy a bigger
alternator, and can sell my old hi amp consuming strobe and position

I've finished testing the Schumacher WM-1562A charger/maintainer
and find it to be a very satisfactory product and good value at
$18 from Wallmart.
The Harbor Freight 38895 charger doesn't kick
into the CHARGE mode unless the battery being serviced is below
4 volts. I DO NOT recommend this product.

Bob, Looking at the battery contactor schmetic, it tells me that I send a
ground wire to it, to make it operate.
Tell me I'm right.

I'm not Bob, but you're right =(;o)
As you switch the positive lead to the battery you have already a + source
for that unit, switching the ground on or off operates the contactor.

LEDs are going to revolutionize lighting everywhere. Buy stock in
LEDs! Eric has got some good stuff on LEDs as well as some products at
www.PerihelionDesign.com and everyone should keep an eye on rapid
developments in this field for aviation.
I just bought a strip of EmeraLights from Wicks for $10 that illuminates
the entire instrument panel with only 70mA of current. I bought a Lumiled
Luxeon 1W LED and nearly blinded myself when I turned it on. Awesome power.
Check out http://members.misty.com/don/led.html for a list of links.
