I have a homebuilt Sky Ranger airplane with a Softcomm intercom, and I
am trying to find a way to connect a cell phone into the intercom. I
tried using an earphone jack plugged into the record output and music
input, but this did not work. Does anyone have a solution, or does
anyone know why this does not work? Thanks

Jack

Jack,

I suspect the problem is the impedance level. Another way of saying
this is that the voltage (but not power) level of the cellphone is too
low to drive the intercom's music input. I added a tiny 8-ohm to
1000-ohm transformer to step up the audio level when I connected my MP3
player's headphone output to the music input of my Softcomm ATC-2P with
good results. (The 8-ohm winding is connected to the MP3 player of
course). Without the transformer the audio level was too low to be useful.)

Also, I'd encourage you to telephone Softcomm in Chandler, AZ. On the
two occasions I've dealt with them, I've found their service to be
outstanding.

There is a basic problem here. Your cellphone is a full-duplex device in
that it receives and transmits at the same time. If you connect a
headphone output to the input of your cellphone and the earphone output
of your cellphone to the music input on your intercom, you have set up a
feedback path. Everything that your cellphone receives will be sent
right back out your cellphone again. You need to somehow isolate the
receive audio from getting back into the mic input on the cellphone.

There are cellphone adapters that put the cellphone between your headset
and the rest of the airplane's audio system. These seem to work quite
well. PS Engineering also has cellphone support in their audio panel.
This is probably the most elegant (and expensive) solution.

Probably the simplest solution is to just wire your audio panel so that
the cell phone appears as another comm radio. You would have to use it
half-duplex and set it up so that PTT activates the mic audio to the
cell phone and mutes the receive audio from the cell phone. A DPDT relay
driven by the PTT line that uses one set of NC contacts to close the
path for the receive audio and the other set of NO contact to close the
path for the transmit audio would make this work just fine.

Hello Jack,

May I suggest this as a definitive answer to your problem.

http://www.mcp.com.au/xcom760/build1509/main-page.html

Click on Accessories then look at the 3rd item down.

I bought one and gave it to one of my sons who is flying regularly in a
C206. When he rings me, I cannot tell whether is in the aircraft or
not. Works incredibly well and I highly recommend it.

Regards
Kingsley in Oz.

Excuse me for jumping in here. I have a ps8000sr that includes a cell phone
connection which I have not been able to try simply because it requires a
cord with a 2.5 mm connection of each end (stereo I believe) and I have not
been able to find a cable anywhere. Any suggestions?

Unless I'm mistaken, I believe it is still against FCC regulations
(47CFR 22.925) to operate a cellular phone onboard an aircraft that
is in the air. This is because the signal will be picked up by
multiple cell towers at the same time and will lock out a significant
amount of bandwidth.

But it does not prohibit the use of a cell phone while on the ground
with the engine running. Very useful when at an airport with out a
tower trying to get a clearance.

Yes of course, did anyone suggest using cell phones in the air? It's
for those last minute calls to Flight Service, family, and for off
airport communication while waiting in line for departure. It is for
that reason I can't justify spending $300 for a cell phone patch.

Now that we have established the need for a cheap solution to this
problem I offer the following

$10-$20 solution,

Purchase a hands free earphone-mic with the flex connection between
ear and mike elements.

Place both elements (ear and mike) in the ear cup of your head set,
ANR probably works best.

I sometimes place the ear element in my ear under the headset, seems
to work a little better.

Talk to your cell phone party over the intercom. The drawback is
that your cell phone party

will hear your take-off clearance and refuse to talk to you any more.

Try it ---- you'll like it!

Wayne,
I had the same issue until I found the cable. PS-Eng sells them but
for a super high price. I bought this one, from here, and it works
great.

http://www.midi-classics.com/c/c23895.htm

Maker: Hosa Technology
Code: CMM-403

That should be some help for you....they're really cheap.
To use this one, you will need to buy a 2.5mm jack for the input.
If you wired a 3.5mm jack, you'll need a 2.5mm to 3.5mm male cable,
which I haven't shopped for.

PS, that PS8000 is one hot intercom. I can't believe how
great it functions in many ways!

You are not mistaken, it is against FCC regs. Although, I haven't yet heard
of a case when the FCC penalized someone for doing so. Maybe because it
happens rarely and mostly in emergencies (9/11 being the most notable
example).
Sometimes it is even impossible to get into the network from the air in
areas where there is no signal problem on the ground.
A cell phone can be very usefull on the ground, though, for getting a
clearance or filing, or calling someone when taxiing. With the engine
running using a headset is very convemient. I use a Lightspeed ANR headset
("X-country") that has an input for cell phone (3.5 mm on the headset side,
2.5 mm on the cell phone side). Same input is used for feeding high quality
stereo audio (auto soft-muted) to the headphones (intercom input can still
be mono).
It is a less expensive solution and the audio is usually of higher quality
than using add-on devices.

Brian, FAA rules aside, are you sure it is ok with the FCC to use digital
cell phones in the air? If so, this is very usefull info.

There are no FCC limitations on that. The FAA limitation (part 91

Brian you are probably right. I can't seem to find any limitations
in the PCS part of the regulations, other than for "antenna height",
and that seems to apply to ground stations.

Cell tower antennas point toward the ground where the majority of the users
can be found, so I'm not surprised that reception might be worse in the air
even with the LOS benefit.

yet heard of a case when the FCC penalized someone for doing so.
Maybe because it happens rarely and mostly in emergencies (9/11
being the most notable example). Sometimes it is even impossible to
get into the network from the air in areas where there is no signal
problem on the ground. A cell phone can be very usefull on the
ground, though, for getting a clearance or filing, or calling
someone when taxiing. With the engine running using a headset is
very convemient. I use a Lightspeed ANR headset
("X-country") that has an input for cell phone (3.5 mm on the
headset side,
2.5 mm on the cell phone side). Same input is used for feeding high quality
stereo audio (auto soft-muted) to the headphones (intercom input can
still be mono). It is a less expensive solution and the audio is
usually of higher quality than using add-on devices.

Unless I'm mistaken, I believe it is still against FCC regulations
(47CFR 22.925) to operate a cellular phone onboard an aircraft that
is in the air. This is because the signal will be picked up by
multiple cell towers at the same time and will lock out a
significant amount of bandwidth.

As I said in earlier messages, the use of *AMPS* cellphones (the older
analog phones that transmit using narrow-band FM in the 800MHz band) in
an airplane in the air is prohibited by the FCC. It is *NOT* against FCC
regs to use PCS phones (digital phones such as CDMA, TDMA, and GSM)
while in flight. As far as the FCC is concerned AMPS and PCS are
completely different services and operate under completely different rules.

Brian you are probably right. I can't seem to find any limitations
in the PCS part of the regulations, other than for "antenna height",
and that seems to apply to ground stations.

One thing to considers: many phone are "dual-band", i.e. they can
operate both PCS *and* AMPS. Often when your phone roams it is switching
to AMPS mode. This would be against FCC regs if you let this happen
while flying. If you wish to use your PCS phone in your plane you need
to go into the phone's settings and disable AMPS mode. I just lock mine
to my home provider and don't let it roam. That solves the problem and
prevents "surprise" roaming charges.
