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

Need to know the headset plug connections for a Uniden GMRS 380

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.

What is right size plug for corded headset for Uniden 6.0 cordless phone?


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!

Uniden troubleshooting


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

Uniden cordless phone model TRU 9466 3.5mm to 2.5mm adapter


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.

On a round trip of 400km,a pilot wants to determine the airspeed of hiis light plane. He flies the entire distance at the same airspeed for the first 200km a steady headwind slows him down by 30km/hour....


v will represent plane's airspeed.


We can divide pilot's trip in 2 parts:
  1. first 200km, when he is flying with speed v. The time it takes him to fly this part of trip is t=200/v
  2. last 200km, when he is flying with speed v-30. The time it takes him to fly this part is 200/(v-30)
The time it takes him for second part of trip is also equal to 1.5-t (because entire trip takes 1.5h), so now we can write equation:

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):

  1. v=(445+sqrt(445^2-4*1.5*600))/(2*1.5)=295.3 km/h
  2. v=(445-sqrt(445^2-4*1.5*600))/(2*1.5)=1.4 km/h
We know that only v=295 km/h is solution because if 1.4 km/h was solution that would mean that second part of trip plane was flying with speed 1.4-30= -28.6 km/h, so that would mean he was flying backwards (which we know he didn't because it's round trip). Speed 1.4 km/h is also not physical solution, because plane wouldn't be able to take off with such small speed :)
