| 162833 | 2003-07-26 20:21:00 | Well, I read the question as "If anyone is standing near me while I am wearing a headset, will I be able to hear them". If I am not off course- yes if you have a headset which has only one earpiece. :-)) |

| 162834 | 2003-07-26 23:07:00 | I may not have worded the question too well. I was referring to hearing people through the PRS Tranceiver, and not people next to me. | somebody (208) | ||
| 162835 | 2003-07-26 23:15:00 | Thanks for all your suggestions everyone. I will continue investigating. The reason I ask is all PTT headsets which are available specifically designed for the UH-040XR are exceedingly expensive (from DSE website), and the design of which would not be suitable in the environment I wish to use it in. I was planning that if I did invest in a set of these, I would use standard computer-headsets (about $20 each), and just get adaptors so there are suitable size plugs to fit into the unit. I would be willing to go with a PTT headset if there were any available cheap enough (under $30 each), and of decent quality. |

| 162836 | 2003-07-26 23:43:00 | Well yes of course they will hear you, afterall that is the purpose of the setup. You speak into the microphone and they hear you in their headset, and viceversa. :-) | Tobas (224) | ||
| 162837 | 2003-07-27 01:12:00 | FYI Simplex is where you transmit and receive on the same frequency. Duplex is where your transmit and receive frequencies are different. Simplex is used to communicate directly between transceivers. Duplex is normally used to communicate with a base station repeater. This is usually placed in a high position, so giving greater coverage. Different frequencies enable the transmit and receive to be on at the same time. If it was Simplex, repeater would receive from transceiver, start transmitting from repeater, which would get up it's own receiver....ad infinitum. |

| 162838 | 2003-07-27 03:47:00 | So does that mean that I can't use a Duplex mode on one of these, and be able to talk and listen through it at the same time? | somebody (208) | ||
| 162839 | 2003-07-27 03:48:00 | I have had a look at the DSE catalogue, and from the description of some of the other models I have come to this conclusion: DUPLEX in this particular context (ONLY) means: capable of having the receive an transmit frequencies offset by 750 kHz, to enable the use of the set with a repeater. You can do what you want if you install a repeater. :D It might be easier to use a PTT headset. If you look for "UH-040XR" in google, you will find a link to someone who has implememented a PTT function ( for data transmission). (Aparrently Uniden don't give out the required circuit information --- they sell an expensive headset :D). |

| 162840 | 2003-07-27 05:39:00 | Thanks Graham. I think I know which site you're talking about - I found one with extensive photos of the inside circuitry etc. for a guy who was connecting it to some kind of data transmission thing. Now I have to re-find it:D |

I would disagree, in that the unit will be unlikely to recieve and transmit (albeit on different frequencies) at the same time. The "front end" will be highly unlikely to have sufficient filtering to exclude the adjacent transmit channel, on such a low cost item. Receive OR Transmit. Not both at the same time. Duplex in this manner simply means receiving and transmitting are on different frequencies, not both at once however. If you are transmitting you are not receiving. And vice versa. So even a repeater is unlikely to help. |

| 162842 | 2003-07-27 08:24:00 | I concur with Godfather's advice. You cannot transmit and receive at the same time. I use two Uniden tranceivers with duplex facility and it is definitely for use with repeaters. Of course, you can do what you want with two cellphones, but although the capital cost can be very low, the talk time is very expensive. No free lunches here unfortunately. Cheers Billy 8-{) |
