r/Baofeng

Hola a todos! Estoy atrapado en una situación difícil. Mi pieza está rodeada por muros gruesos de cemento que bloquean toda la señal, y la antena original de mi radio casi no capta nada adentro.

Tengo un Baofeng UV-5R y quiero construir una antena casera para llevar la señal hasta el techo (unos 3 metros de altura) para tener mejor alcance y no tener que salir afuera en momentos de frio o lluvia, pero tengo estas limitaciones extremas:

Presupuesto: $0 (No puedo comprar nada por internet ahora).

Materiales: NO tengo cable coaxial en casa busqué por todos lados sin éxito.

Objetivo: Necesito una forma de armar una antena de hilo largo o en forma de T usando cables básicos de la casa (como cables eléctricos viejos de desecho o cable de red) que se pueda conectar de forma firme y segura al conector SMA-Female de mi UV-5R, sin romperlo y sin usar cinta adhesiva que se suelte a cada rato.

¿Alguien ha logrado armar una antena de cable largo para esta radio de mano sin usar coaxial? ¿Cómo conectaron el cable pelado al pin de la radio de forma segura? Se agradece cualquier idea ingeniosa. ¡Gracias de antemano!

"The Austin N5OAK Ham Radio Club Repeater seems to be pretty active.  That shouldn’t surprise us much because the club has a lot of activities and a lot of enthusiastic members.  Still, we wondered just how active and opened the spare parts drawer to see if it held a solution."

"Turns out the spare parts drawer did; take a look at the wiring diagram at the top of the page.   We simply used an Espressif ESP32-C3 Dev Board with an input pin wired to to the output speaker of a Baofeng HT tuned to the repeater frequency.  We monitor the C3 input pin and if it sees a signal the repeater in transmitting.  We push that data to Adafruit IO at the top of each hour to graph the history."

Baofeng dmr will not work on a private channel we made , but the private channel will work if I pick it through the talk groups we named it room . It’s got the correct color code and time slot and my friends is programmed same way , but his works on the private channel with other friends . Just wondering if anyone had this issue and was able to resolve I copied his code plug and it’s still a no go . Thanks for any info on how to resolve .

Hello I recently got a DM32 to listen to my local counties Fire dispatch and EMS dispatch cause Im in EMS and nerd for this type of stuff and want to know whats going on. Anyways, my county got a structure fire recently and wanted to listen in on the Fire Tac channel but couldnt. I have an understanding of the CTC and CTCSS tones but I looked up the Fire Tac channel it listed and DPL 251 tone. I looked it up and it seems DPL is just Motorolas term for a DCS tone so it should be interchangeable right? I did see inverted vs normal tones but do I need to input a different tone into CPS for me to be able to listen in?

I’m going back and forth on if I should get a DM-32 or Uniden Bearcat BC125AT. I don’t really want this for transmitting but just to hear local frequencies and both of these are more entry level. I know the Uniden is a scanner only and is better at receiving, but the DM-32 can pick up DMR. I’m wondering if the scanning feature on the Uniden is worth getting over the DM-32 to hear local frequencies. Has anyone compared these two and seen differences in reception range or ease of use?

I own a couple BF-888s , they work fine, audio out could be a bit more powerful, but for the price, the radio has been excellent for GMRS and the 70cm repeaters. I saw the BF-C2's on sale. My guess, the internals are the same.

Anyone know if there are any differences (minus the flashlight feature which I don't need) between the two models? Im looking to buy a few more! Audio power, PTT and other controls, durability, charger, batt life.

Thanks!

Can anyone tell me if the Baofeng UV-5R Mini would be any use?

I work on an extremely large construction site and looking for something that I can speak to my other colleague at the far end of the site.

Also, I’m here. There is a number of cranes working who use UHF radios. Will I be able to hear what they say or scan all frequencies to find them?

Got a few recommendations to try GMRS instead of meshtastic for communication within our scout troop so I'm checking here to see about radio recommendations. We camp frequently in wooded hilly areas without cell reception. I'd like to be able to have the patrols be able to communicate with one another when separated. Any recommendations of a GMRS radio and antenna upgrades if needed that would work in this situation. Thanks!

I'm hoping someone can shed some light on whether I am doing something wrong or whether these things are just more limited than the manufacturers are letting on before I put the in a box and return them.

I bought 3 888s from BaofengUK I got a simple UK biz license - my UHF freqs run from 449 to 458, I cant get these things to work for love nor money with my frequencies, the squelch breaks but there is no voice transmitted at all, heres a pic of my config, I turned off all the obvious stuff that I thought might not help.

So after quite literally hours and getting no where, I decided to write back the original config that the radios came with and of course all those illegal freqs work great but not the ones I actually paid for, can anyone help me maintain my sanity before I bin these off, what am I missing?

As the title says, im considering buying a DMR radio, i need the radio also to be able to communicate on analog, and gps would be a giant plus. Im located in EU.

Any help shedding some light on the which to choose or if there is another one in the same price class.
