| Subject: | Single radio, two frequencies |
Does anyone know of a COM radio that can monitor the standby
frequency at the same time as the primary frequency, as the XCOM 760
does? I'm looking for one in a standard thin radio stack form factor
as opposed to a round instrument package.
Basically I'm looking for a way to eliminate one of my two COM radios
but maintain the ability to listen to ATIS/AWOS without leaving the
primary frequency I'm on.

Dave,
You mentioned a COM radio. The SL-30 NAV/COM has the capability of
monitoring a standby frequency while being tuned to a primary one. It
also has a very thin vertical profile with standard width.

How much do you want to spend? The Garmin SL40 is a very nice radio with
standby frequency monitoring.

King made a 2 channel frequency selection tied into one transmit
section. I have one stored and am not sure of the model number but
think it is similar in form to a KX-170. Its old technology and
probably does not meet current frequency requirements. I assume more
info is available from the experienced people. I can dig it out if
there is any interest

I had forgotten about the SL-40. I'm trying to come up with an
alternative to spending $10,000 on a 430.
Thanks for all the suggestions, guys.

I'm not answering to your questions, which are partially also mine.
I will appreciate if you share the conclusions you arrived at.

Subject: AeroElectric-List: ANR Headset Power without batteries
I have a Telex Stratus 50D that I ordered with a "Lemo" connector (to
use ship's power) and battery pack as an accessory. This battery pack
uses 6 each AA batteries.
My dilemma is that I own 2 aircraft (both tandem seating) and several
headsets (all ANR) and need to eliminate all battery packs. I have a
strong dislike of things flopping around in the cockpit. This dilemma
seems to be exasperated by the lack of a standard power voltage and
connector to drive the ANR in all headsets.
My questions are:
1) What voltage does my 50D headset ANR run on ??
The specs in the Telex website differ from my actual unit in that my
unit is using 6 ea AA batteries. The website says this unit runs on 4
each AA batteries. If it is running on 9 volts it will help my
situation. I've contacted Telex about this and am waiting for an
answer.
2) One of my other ANR Headsets is a helmet with
Headsets Inc. ANR system that runs on 9vdc. I spoke with Headsets Inc.
and he didn't know what connector he is using for the power - would
anyone here know ??
3) Does anyone have a sense of a "standard" connector
configuration emerging ??
4) I believe the connector configuration I will be
choosing will be:
a. Standard microphone connector
b. Standard headset connector
c. Similar style but different sized plug for ANR power -
powered at 9 vdc.
This would allow each headset with this configuration to be used in
any of my aircraft; or any other aircraft with either no ANR or an
auxiliary battery pack to power the ANR. Would you please give me
feedback on this plan ?? Is it optimal ??
5) What power connector would anyone here recommend
??
6) Is there any other source for this magic Power
Supply to supply good 9 vdc ??
7) My wife has the Bose headset - I'm guessing it
runs off a different voltage given it uses 2 each AA batteries. What
can I do to make it fit into my scheme ??
My design goals are:
A) Inter-compatibility (or as much as possible)
between my headsets and my aircraft.
B) No battery packs in my 2 aircraft
C) Ability to allow anyone else with standard
headsets to plug into my aircraft (with or without their own ANR).
D) Ability to use my headsets in other aircraft not
equipped with my ANR Power plugs - using an auxiliary battery pack of my
own.
E) Keep all of my headset cords short with connectors
located near my shoulders (I have done this before and it works very
well).
If this is of interest to anyone else I would be happy to post
whatever findings I come up with.

I wish I had all the info on it, but a few years back when
I bought 4 of the ANR upgrade kits, I decided to do-it-myself
and bought a larger isolated DC-DC converter and bought the
jacks and put them in for all 4 headsets. Last year I put
the guts of all of this into my RV-10, but now I have
Bose sets. At the time when I was using them, it was fantastic
to have the power jacks in the plane. I do remember though that
back then to do a good job I ended up paying not too much
less than if I would have just bought 4 of their jacks
with the power converter in them. I'd recommend either
going with theirs, if you have a 2-place plane, or building
your own only if you have a 4-place plane. I do think you'll
want the ground isolation. Just think of it as one of those
great things that later you'll forget the pain of buying the
jacks, and make it easy on yourself if possible though. In the
end, it will be easier to take the jacks out and move them
to another plane, or sell them along with your headset if
you upgrade to something else.

Out of curiosity Bob, would you then mainly advocate z-14 for new designs with
a 20A alternator. In the past it seems you have suggested z-14 over z-12 for
people in the planning stages (correct me if I'm wrong). Maybe a z-14 that uses
the second bus as a smaller main alt. out e-bus, not used for starting...smaller
battery...
In what instance would you use z-12 over z-14 with a 20A alternator? Save a little
$ and #?
