Question about Uniden GMRS/FRS 2-Way Radio Value Pack with 10-Mile Range

My flying club wants to use the Uniden GMRS 380 for plane-to-plane communications. We must use flight helmets with built-in headphoners and mikes. I need to know the headset plug arrangement Uniden uses, headphone impedance, type of mike, and mike impedance. Having a schematic of the radio would work OK.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

The cordless phone headsets use a 2.5mm plug.

The larger 3.5mm plug is used for the PC or

laptop computer headphone connections.

The model number for your cordless phone is

on a small sticker under the battery inside the

handset. Entering this number at

www.manualslib.com will allow you to

get a free copy of the original owners' manual.

Good luck!

was the old phone connected to a Private Automatic Branch Exchange P.A.B.X like for example a comander system if so the new phone would have to be a PABX type phone extention type. I suspect the Uniden phone is not compatible with the PABX extension socket.

I do not know what phone system you are using you might want to find out the model number of your PBX device and research if it uses VOIP = I can only guess that this is the situation

If they both cover FRS/GMRS frequencies, they should be able to communicate

Hi Ted,

I'm looking for a solution to a similar problem. I found this adapter that might help you: <http://www.theheadsetbuddy.com/pc-computer-headset-to-uniden-phone-adapter/>I can't vouch for it first-hand since I haven't used it but am about to purchase it. It looks like you should be able to use a headset or separate headphones and microphone with it.

v will represent plane's airspeed.

We can divide pilot's trip in 2 parts:

1.5-t=200/(v-30)

We also know that t=200/v so we substitute that into equation:

1.5-200/v=200/(v-30)

To solve this equation we multiply it with v*(v-30)=v^2-30v first. We get:

1.5(v^2-30v)-200(v-30)=200v

Now we get rid of brackets:

1.5v^2-45v-200v+600-200v=0

or

1.5v^2-445v+600=0

This is quadratic equation, so we get 2 solutions (sqrt= square root):

We can divide pilot's trip in 2 parts:

- first 200km, when he is flying with speed v. The time it takes him to fly this part of trip is t=200/v
- last 200km, when he is flying with speed v-30. The time it takes him to fly this part is 200/(v-30)

1.5-t=200/(v-30)

We also know that t=200/v so we substitute that into equation:

1.5-200/v=200/(v-30)

To solve this equation we multiply it with v*(v-30)=v^2-30v first. We get:

1.5(v^2-30v)-200(v-30)=200v

Now we get rid of brackets:

1.5v^2-45v-200v+600-200v=0

or

1.5v^2-445v+600=0

This is quadratic equation, so we get 2 solutions (sqrt= square root):

- v=(445+sqrt(445^2-4*1.5*600))/(2*1.5)=295.3 km/h
- v=(445-sqrt(445^2-4*1.5*600))/(2*1.5)=1.4 km/h
