Nice and clean install! I did some antenna / cable work outside my station and I ended up disconnecting the ground for a short while while I was feeding wire info my house. No storms, just cold and windy. I ended up taking in a huge amount of static build up inside my station. I ended up connecting the ground again and it slowly went away. That wind and cold air is just as dangerous, if not more than a near by strike. People don't understand those "lightning arrestors" are only designed to bleed off static build up from the mast, nothing more. Also, I use a ground bar inside my house and bond everything separately, no piggy back as a ground loop or other bigger issues can happen. If you radio has an electrical fault it will touch all of the devices in the chain instead of it's own path to ground....but follow your local code not a random comment.
Very well documented video on your setup, I will say taking your time plus attention to detail will always result in a outstanding product which you achieved both mechanically and aesthetically. Well done

Very nice set up, very useful video with simple explanations
Nice to hear you this evening Mark. I look forward to learning from you guys.
Mark, I've talked to you several times, Now seeing you in person was great. I'm the problem child that can't seem to get my radio equipment correct, anyway, I liked your video, Edwin WROZ446, Willis, TX. Happy Easter
Great video, gave it a thumbs up and subbed👍
Nice set up. I lived in the Cy-Fair area of NW Houston for many years. Nice area. I like how you grounded everything.
That's a very cool setup Mark, I like it! you did a great job and you are very wise about the grounding, tnx Man!
Thanks for the video. Clear and concise!
Nice setup and well-presented.
Ahh, Mark... How did I miss this! Great explanation of your station setup. I dig the antenna mount and envy the height you have achieved. Now go make me one of those decorated tacos! I'm hungry! de WRCU527, reading the letters and numbers.
I live on the extreme far western edge of Humble. I’m operating with a non-grounded GMRS fiberglass 17” vertical antenna mounted on a 20’ pole, and, it’s performing so much better than I expected. I’m hitting many of the repeaters and talking to New Orleans, Baton Rouge, California, Missouri, and, all over Texas to name a few. The radio I’m using is a BTECH 50V2 mobile [as a base unit] and also have UV-5R PLUS and UV-9G HTs [using the Nagoya UT-308UV 21” mobile antenna with them in the truck]. Nice video! Stay safe! ~Jim WRXY695~
what brand of antenna do I have?
I lived in the Cypress Fairbanks area of Houston. I was a Firefighter/Paramedic with Cy-Fair Fire. Nice area. I now live in Arizona where the weather is a bit better year round.
Hey man I saw this posted on texasgmrs, just happened to stumble on your video here. Looking forward to getting my station set up and talking to you guys!
Thanks for sharing!
This is WRJK797 calling WREZ914, saying awesome video and your production quality has my attempts blown out of the water. I like the format and how you showed your whole base station.... so awesome and I am jealous!
Quentin!!! -WRNX261
Audio sounds great here, just at the very end a little low for a couple seconds. Great job.
Was so glad you went into the grounding. Too many leave out.
Nice setup that should have some range.
Nice Videos. I love when it gets right to the point. Keep em short and sweet. WRJL600
Great video Mark, hope to hear you on the radio sometime WRUD453.
HY THIS IS WRNB581 TYRONE!
Very, very good job. I will refer to your video for upgrades to my base. Thank You, WRJS450 Bob Tallahassee, Florida
Nice!!! I keep telling my friends to ground the antenna
hello mark....nice station! DE YC0INU
Probably could do with a different microphone for your camera or phone. Whatever you recording these on. Also looks good. I think I heard part of my conversation on the regional net there.
Hey Mark...Now I'm able match the name with the face and I'm definitely a subscriber to ur channel...LOL...I accidently ran into ur vid while searching the net so I can get my little "piece meal DIY " GMRS radio contraption working and on line...(sometimes we gotta work with what we got)...I almost cracked myself up and woke up the neighbors busted out laughing when I associated your name and voice with your face...For me it was like looking at a long lost friend I haven't seen indecades and we picked up where we left off....I'm on the NYC Broadnet out of the 625 Bronx repeater and try to attend the Broadnet GMRS night roll calls...( Which I REALLY appreciate you NET Controlling when ur available)....I became involved in CERT and as a result have stepped up to do Net Controll and take on the Comms resonsibilities for my CERT division for Redio operations inspired by they way you manage the NYC Broadnet GMRS meetings....That being said you can probably tell by me searching YT that I'm trying to get my rig up and going and learn all I can ...I have Juan 347 helping whenever he can by offering great tips and advice...it's a work in progress for me, however I'm motivated to make this work...it's a Pleasure to meet you in a strange and convoluted way, but thank you for sharing your experience for all you do in helping and encouraging us all to progress forward in GMRS and HAM radio....the best to you and ur Family...sincerely from **** 525
Awesome, y’all sound like hams.. looking like y’all are having UHF fun lol
Nice rig, Mark!
I'm running the same antenna and coax and it works wonderfully.
Have you experimented with running a mic into your garage as well?
Clean install !!! THIS is real ! Why does everyone have to run out and get an ICOM 7300 ? I'm subbed ! 👍
thanks nice video
i have my gmrs repeater here on hockley sadly is down for maintenance but it will be back in 3 weeks
👍👍👍👍👍👍
Wish there was a NET repeater here in N California.
Did you have to tune the antenna ? What did the swr get to?
What is the range you can get base to base or Base to mobile or portable
do alot of ppl simplex there on GMRS or repeater duplex ?
I wish I knew how to build all that .
comet antenna? what is the frequency coverage on that antenna? the package says its a 70cm antenna.
The Comet CA-712 EFC runs a freq range of 460-470MHz
I recognize those voices anywhere 😂 WRNX261
I can't help but notice that you are using a base station antenna that is tuned to the 70cm UHF ham band. Was there some way that you were able to tune the antenna to GMRS frequencies to get a usable SWR?
This will answer your question www.hamradio.com/detail.cfm?pid=H0-001504

Wow!!! Thanks for the reply.👍 That must be a heck of a performer.
@@radiohobbyist13 This is the one he has in the video. I have the same antenna and swr is 1.5 on both bands. I have also used this on Ham bands without much change in swr. www.hamradio.com/detail.cfm?pid=H0-006893
I'm a ham but thinking of GMRS for my family members who don't care to get licensed. I have a Diamond X700 that is for ham bands but I have checked and its actually not that bad in the GMRS frequencies 1.5 to 1.8 swr so its actually usable on both. Might just be my particular installation so don't just take my word that a ham 2m, 70cm antenna will work for GMRS.
By the way, its 1.1 to 1.3 swr in ham bands, excellent antenna.
The grounding is absolutely wrong!
At 5:55 "If you have a lightning...surge spike, you immediately have the same potential..." During a lightning hit, nothing is immediate. The rise time is such that you could have several million volts at the point of entry aloft and instantaneously have 0 volts at the ground rod(s). Contrary to incorrect belief, grounding/ bonding is for household AC purposes - not lightning protection. You should also have a home run from your radio AND your power supply (not a daisy chain).
You should never connect the antenna ground to the base station ground the too groundings should never meet you could ground your station to your cold water line coming in to the house
I THINK THAT YOUR MISTAKING CODE SAYS OTHER WISe
@@AndrewMurphy8383 No, you should never bond your antenna and station grounds together. It forms a ground loop that will feed any near-strike potential from antenna to the house ground! A direct strike will damage/destroy the antenna and/or radio equipment and potentially cause a fire. The antenna ground is mainly for bleeding static build up on the antenna itself, caused by rain, wind, snow and a nearby strike! The only way to protect your equipment from a strike is to disconnect the antenna(s) and unplug all ac cords.
On another note, if the AC equipment (power supply) is equipped with a 3 wire AC supply cable, then the chassis is already grounded. Never ground equipment that has an AC service grounded supply cable!
Actually your ground wire will do with sparks, but not sure with a direct strike, your wire is not enough "straight" from the antenna to the ground (air is potentially conducting then) and you want to have as straight a line as possible. Well that's the way i'd do if I had to make my own. And I'd use 1 gauge instead, stranded, bare not necessarily copper.
With a direct strike there is No wire that will survive the strike.
@@1OFGODSOWN Not sure, do you think they have to replace every wire when there's a strike on some lightning protection system?
One problem I see with your grounding. Where you have your lightning arrester running to ground. And then, running your equipment (radio, power supply, and audio amplifier) to the same ground rod could potentially cause RF damage from a close lightning strike. Or serious injury to anyone within the household in a direct hit. It should be run (your Radio equipment) to a separate ground rod at the lest, 6 feet away. Then Bond that to your house ground! A Second ground rod, 8 to 12 feet away is overkill but, better safe then sorry.
Just saying 💥
As others have mentioned, you should never daisy chain grounding wires, nor should you run one grounding wire to several pieces of equipment! The common ground in the radio area should be a separate piece of metal that you attach a separate piece of wire to each piece of separate equipment. Keep in mind, the way you are doing this could create ground loops. This is textbook poor grounding of equipment. Also, flat strap is far better for grounding equipment than simple wire.
I was under the impression it was illegal to modify a different service radio to transmit on GMRS? I thought the radio had to be originally built for the GMRS system? I’m no expert on this and don’t know this for a fact could be just Internet rumor but I thought I’d throw it out there.
Yes, all radios used on GMRS are supposed to be FCC type accepted, Part 95. However, there are only a few manufactures who make radios for GMRS, so, many users have had commercial radios reprogrammed to the GMRS service. As far ss I can find out, only Midland and Btech make type accepted radios for GMRS mobile use (can also be used as base radios with an appropriate power supply and base antenna). I will be getting a Btech GMRS rig when I get my GMRS license (when they finally drop the cost to $35.00 for the 10 year license). The Btech is a 50 watt mobile for around $200.00 and has all of the GMRS frequencies programmed in but you can program the CTCSS/DCS tones and name the channels. It also has the capability to receive NOAA WX stations and can also be used as a VHF/UHF scanner radio. This radio will only transmit on fhe GMRS frequencies!
Very nice clean setup. WRWR298

buuuuuuuuuusch
Audio sucks
What are some reputable resources for the repurposed Kenwood radios?
