Thanks for your input. I had planned to use my cell phone only as a back-up in
an emergency situation. I discovered that the transmitter does not work well
while airborne, although it does provide a way to receive up to the minute ASOS
weather recordings. This could provide valuable information in choosing an
alternate airport if my aircraft experienced complete electrical failure.

Maybe I should keep quiet on this, as I don't want to create
controversy (this subject always does), but the subject has already been broached.
The
subject is cell phone use in aircraft (including your private aircraft).
I'll just say this, and then you can do the research to confirm or dispell my
statement. Cell phone use in your private aircraft is legal .... until the
wheels leave the ground! Once airborne, cell phone use can disrupt and interfere
with cell phone communications across a very wide area (line of sight just like
VHF), including emergency services. Your encrypted cell phone number is
automatically recorded as a matter of record, and you can be held accountable
for
disrupting service. Don't look for it in the FAR's! It's covered by the FCC!

I agree, John! In an emergency, I'll use any and all communications I deem
necessary, including semaphore!

--> Avionics-List message posted by: PGLong@aol.com
Looking for a small microphone to put in my headset earphone cup to pickup
the audio for my video camera aux microphone input. Or, would it work to use
the rear seat headset jack ear phone portion for the audio to directly input to
the camera? Would there be an impedance matching problem? Anyone done this
that could guide me thru the process?
Thanks, Pat

You can build or buy an attenuating cord for this and just plug the
headset jack into your cameras mic in. I built one a few years ago,
but I think maybe even Aircraft Spruce sells them, or you could
even try Rad shack.

My intercom has a "record" jack. I just used a standard rat shack patch
cord, and impedence wasn't a problem. Picked up everything that goes to the
headset. leave the squelch down to pickup engine sounds, wind noise, etc. (gets
a
little annoying, though). Do a short video and check it.

Several of you have advised me that an a VSWR check should be my next step. (my
radios bench checked good, receivers are excellent, but my transmissions are
weak and scratchy)
I contacted a gentleman who has a 'ham' business in town. He deals pretty much
with the shortwave spectrum, not the VHF. He told me that he doesn't have the
MFJ-259B meter. But, he feels sure that I can find someone in a local club
who does. He mentioned that the meter needs to be inserted into the feed line
between the radio and the antenna and he suspects adapters might be required
to do that. Before I start trying to find someone with a MFJ-295B, what should
I know about inserting the meter into the feed line? Remember, I am Radio Illiterate.
I just want to be sure that I can provide the 'ham' with the required
adapters and any other information that he might need. It is possible that
will have no experience with aircraft radios.
Thanks,
John Linman
To locate a local ham, look for a house with an "antenna farm"! Many hams
these days have the MFJ-259B which is a very good tool for checking VSWR
across the VHF band. This is a very easy test to do. One only needs to plug
the
coax from the antenna into the unit and turn a knob.
