WRJT772 Thomas Repeater Build
Hi, sorry for taking so long in posting my technical videos.
This video is very special to me, for many reasons, first, I helped a friend own his first GMRS repeater, his name is Thomas Duke WRTJ772, he is from South Carolina, we actually met on an open Zello channel called GMRS_TWO_WAY_RADIO a gentleman called Scott from Wisconsin sponsors the channel and I found it by accident, well to make a long story short, we basically talk every day and I mentioned that I just retired from Motorola and that my hobby is building repeaters, we got to talking and I had mentioned that I was looking for a nationwide network, he suggested the Octane network, once I finished building this repeater and afte...

Hi guy's, sorry, it has been a while since my last post. This video shows the finished product, the relocation of my Home Network, It took me a couple of days to complete, since the attics here in Miami Florida technically never call down to a level of Confort.

How much you charge build one for gmrs im also a ham
Great setup Thank you so much for the awesome information God Bless.
Great progress from when you first bought one from me. Its a tough business and starting to get not really fun anymore. Not scalable at all and hard to get good deals. Then HAMS / GMRS users are dirt cheap, if I want to sell 5 a month at least. I'm not gonna do this to sell 1 a month. So if I sell a repeater for 500 bucks, have 150 in the radios, 150 in the computing, thats only 200 bucks in my pocket for 4 -5 hours of work. Which isn't really getting close to my $100/hr rate for engineering projects like this.
Amazing!! Love the fact that you’re using Motorolas.
@wd4ehutechnicalsite314 Could you possibly give me an idea of where i can obtain the software for discontinued radios like the m1225 for example? I have several prior public service units I obtained when our FD changed to kenwood. I interested in using them for a couple mmdvm pi repeaters, but the software isnt as readily available as other manufacturers. Thanks, James.
love the setup
Are you still building these?
Did you stop making videos? WRWQ208
How did you handle the station identifier for the station? Glenn N6JAI
Did you solved problem?
are you still building the gmrs repeaters looking at controller fans and voice workings thanks Merle KB7MUB in az or a repeter with some parts I can send you ........
I’d love to learn how to build one of these repeaters
Adonde puedo comprar esa controller para mi gmrs reapeter saludos y gracias
tomas usred programa esas repeater las kenwood tkr820
What happen you said more videos to follow..yet no signs in a year. Are you ok?
Another great video.
Incredible attention to detail is very well explained. Would love to meet you in person. Thank you, W4KWS
Hi saludos me puedes enviar tu Gmail par aserte unas preguntas soy radio ofisionado también
Excellent build, good sir.
When I build mobile based repeaters I set the tx radio to 10 watts and then run it into an external amplifier that takes 10 watts in and sized to whatever output power the output needs according to its use. Currently working on a Desktrac repeater and converting it to P25 with the Repeater-Builder board. Fans and amps are cooled via a thermistor controlled switch. I could have sworn I saw something in the past that used a RaspberryPi with an interface board that would send out a push notification to those responsible for the site. One could also interface a power monitor to the system to let one know what is happening with output power. Nice build!
anyone know where to find the programing cable or how to make one
Interesting rig. Love to have a GMRS machine here
No one seems to go over the setting for 1 hour beacon and the cw ID wit ha voice board
Looks awesome. Any advise on hooking a Quantar into a raspberry pit to work on a network.
Can you do voice with these vrm radios?
What the price for the repeater ?
Dude built a repeater better than the US government ever could.
How much to build a repeater like that without the option of connecting to a network? Just a stand-alone repeater? Nice work!! 73 de N5BIG / WRTL267
Good evening, Curtis, sorry for the delay, turnkey, about $800.00, if you need more information, you can look me up on QRZ (WD4EHU)
I love your videos on repeaters asere! I hope you’re still making them. You also sound like Andy Garcia the actor-thank you for sharing your knowledge!KC2YOK
Good evening, John. Thanks, we try.
niceeee....muy bonito el repetidor...
Absolutely brilliant!
i am thinking to do something like this,but in the GMRS with 50 watts MSC2000.i have 1 video of the radio in my channel
I am actually in the process of making one myself and found this video
was thinking of having the receiving side be just a well tuned hand radio because you don't need a lot of power to receive
Nice build. What software is running on the pi? 73 from KK6YWG
Good evening, Jack. Just the latest Pi-star software.
Man so more info!
Very informative video on the TKR programming. Much easier to understand than the manual is! Is the PL frequency done the same way and do you have a video of the process in the works possibly? Thanks... N8FXC
Thanks for the video. I am trying to program the ID-O-Matic but unable to get Windows 10 to recognize the ID-O-M. Do you have a solution for this? Thanks again.
Que manual o documento tienes para elaborar esa interfaz y epecificaciones gracias
What cables were used?
do you have a text document of what you did? I have a couple of the VRM850's and would like to use the heads for data
Also are there any settings that need to be set to specific values in the repeater in order to work properly with the Pi/MMDVM modem?
Hi, sorry for the delay responding, besides all of the connector's DB-9 and DB-26 that have to be created, you need to make some changes to the CPS, like where you want to be your PPT output, flat audio settings and so forth, it was challenging at first, since I could not find any information out here on how to perform this task, if you send me your email, I can forward the information that I have compile up to now. 73's de Ross Fernandez (WD4EHU)
What kind of cable/adapter did you use to interface the DB9 on the MMDVM modem and the Hytera repeater?
Hi!!, the cabling I utilized, was a Belden 8 conductor shielded cable. I highly recommend shielding due to the RF environment present during transmissions. The connections were relatively easy once I knew the pinout, you would only need a special DB26 pin connector and a DB9 both male connectors. There are two ways you can go with the SST32M modems, one by Repeater builder, who's board will accept an dc-to-dc converter and this way no need to power thru usb, this converter will do the 12 to 5 volts conversion and the other is a regular board by anyone else.
