Can the TK6188 walkie talkie be placed on a high place as a relay for the other two?

No, to put it this way: you now have 3 walkie-talkies, each numbered A, B, and C

What you mean is that you put A on a high place (e.g. on the top of a 30-story building) and want B and C to pass through A to increase the communication distance.

That's what it means, right?

If so, it is not possible, the reason analysis:

1. When machine A is in a high position, machine A can receive signals from B and C well, but it can only support A-B or A-C communication, and when A and B communicate, the communication distance is significantly improved (A and C are the same).

2. To put it simply, at present, your device supports point-to-point communication, but cannot support point-to-multipoint communication.

2. Buy second-hand relay equipment, the common ** is 300-thousands of yuan, and the investment is relatively large. If you do not have financial support, it is recommended that you use a mobile phone to set up a trunk.

3. New relay equipment is excluded, because ** is very high.

1、Huawei small relay (just search for this,I forgot the model),This is 5W,**Probably between 300-500,If the landlord's communication requirements are not high,You can consider it。

2. UP450 relay (it should be this), I forgot how many watts of power this is, anyway, it will not be less than 25W, ** about 500 yuan.

3, Jianwu TK-720 820 relay, this power seems to have 40W, I don't remember the specifics, this ** is estimated to be high, probably between 1500-3000.

Note: The above recommended model ** is estimated by individuals according to the second-hand value, which does not mean that this ** is accurate, it may be higher or lower than the market price, and it is for reference only. Thank you for **pk.

No, there is no duplex.

First of all, you need to know the frequency of the other party, and then enter the number in the range of 400MHz-470MHz, or press the left scan key to search for the channel until the other party is searched. If you have two walkie-talkies in your hand, if you need to talk to each other, you can input the two walkie-talkies to the same frequency, and then save them to the same channel for direct use in the future. Method:

Enter any frequency you want in the range of 400MHz-470MHz, such as keyboard input, then press the FUNC function key on the left, press the up and down keys on the right to select the channel (such as 2), and then press the scan key to deposit. After turning on the phone, directly adjust the + and - buttons to channel 2, and the two walkie-talkies can talk to each other. When on a call, press the 'PTT' button on the left side to speak, and the other one does not press any button to answer.

Whoever speaks presses PTT. It's a good idea to add a sentence when you're done on the call'over'。

I don't know if you're talking about KYD (Keyida)'s TK-6188, the walkie-talkie with display frequency has a special introduction in the manual, you will see that it can be restored to factory settings, after restoring factory settings, you before.
