Yes one can use an amplifier on 2m and 70cm. But comparing apples to apples by using a 50 watt 2m/70cm mobile to using a MGRS 50 watt mobile, then there will not be any difference in the range with 70cm and GMRS.

We have our 70cm repeater antennas and GMRS repeater antennas on the same tower. The 70cm antennas are higher but the actual range is the same for both GMRS and 70CM. We get between a 30-35 mile coverage radius with the usual dead spots due to local terrain. Our 2m repeater antennas are at the same height as our 70cm antennas and we get a 80-85 mile coverage radius with it. Those ranges are all with using 50 watt mobile radios and good mobile antennas with the proper ground plane. And before "some people" state how they get 200 + miles with their GMRS radios, they live in the most perfect ideal location across wide open and flat desert terrain. Real world range will be anywhere from 15 miles to 50 miles depending on what part of the country you lie in and what the local terrain is like.

I have two KG-1000G radios along with one KG-XS20G. I have not had any issues with all three radios. The XS20G is a very nice 20 watt radio and easy to program through the radio or with a computer. Actual output power ranges from 18 watts to 25 watts. It also has the same screen and menu setup as the KG-935G hand held radio. The plus of the KG-1000G is that it is 50 watts and has a removable faceplate. That makes it nice when space is limited like in most new vehicles. It costs close to the same as the Midland MTX500 and MTX575. I have used all three and prefer the KG-1000G. A lot of people are happy with the Radioddity DB-20G. SO that is another option for you.

Many HF antennas were made with twin lead wire from Radio Shack. And I still have a great set of Radio Shack Realistic speakers that still sound great after 40+ years. I have to agree with @SteveShannon, I would rather use a good quality 75 ohm coax over some cheap craptastic 50 ohm coax. I don't even like using the cheap Amazon or eBay coax for short jumpers even though loss is not a factor with such short lengths. The biggest issue I have is the lack of shielding in the cheap stuff.

One of the main differences between cheap coax and more expensive quality coax is the amount of shield braid used and also the materialist is made from. You will only see about 50-60 percent of the dielectric being covered by the shield braid on cheap coax where you will see 70 to 100 percent coverage in the more expensive coax. The amount of shield braid makes a difference in how it protects against RFI and will also act as a better counterpoise when the coax is used as such. It is common to use the coax as a counterpoise when using end fed half wave antennas for HF versus running a separate counterpoise wire.

I reran the numbers using RG-58, RG-8X, and RG-8 with the length of 15 feet since that is the average length used in vehicle installations. RG-58 RG-8X RG-8 Now most mobile antennas will not have 5 dBd of gain so you will have to adjust that number using the calculator.

I ran the numbers using the https://kv5r.com/ham-radio/coax-loss-calculator/ for several types of coax. Here are some screen shots showing the losses for 100ft of coax. LMR400 RG-8X RG-8 1/2" Heliax

I've tried the Nagoya 701G and 771G on my KG-935G and the stock Wouxun antenna performs better. I do see an improvement when using the 771G on my Baofeng UV-5R GMRS radios.

I do wish that Wouxun would include a way to adjust mic gain in their radios. And yes the KG-1000G mic is on the hot side. Another thing that greatly helps is holding the mic at an angle to your face instead of flat. PS: ignore Negative Nancy

Oh I can feel my blood sugar levels spike just looking at that photo. Why tease a diabetic like that. Outside of just stocking one type of connector and keeping the prices and inventory down, there is absolutely no reason to use PL-259/SO-239 connectors for any VHF/UHF radio when N Type connectors are better. While N Type connectors are definitely more weather resistant, I still wrap them just like I wrap PL-259 connectors out of habit.

It's always a trade off when determining what type of coax to use. For the average person setting up a base station where the coax run is 50 feet or less then LMR 400 and equivalent is fine. Just like every type of antenna is a compromise. Go with what works best for your situation and that also fits your budget. Not everyone can afford LMR 600 or 1/2" Heliax cable.

You will get a baker's dozen if you can get all the radio manufacturers to start using N Type connectors on all HVF/UHF/GMRS radios.

Two very important tips to always remember.

I'm glad to hear that you redid the connections and that improved things for you. While ABR makes excellent coax cables, their ABR240-UF is pretty much the same as RG-213. Line Loss per 100 Feet RG-213 - 5.28dB, 70% loss LMR240 (same as ABR240) - 5.40dB, 72% loss LMR400 - 2.87dB, 48% loss RG-58 - 9.16dB, 88% loss Again, The calculations were made using 50 watts in and an SWR of 1.5. I used the https://kv5r.com/ham-radio/coax-loss-calculator/ to get those numbers. Your numbers will be different depending on the actual gain of your antenna. Higher loss cable will actually show a lower SWR due to loss. Go with the best that you can afford along with the acceptable losses for your needs. I would go with the DX Engineering 400MAX or R&L Electronics Jetstream 400Flex before going with RG-213/ABR240/LMR240. ABR coax is good stuff and I use their cables for all of my portable/POTA setups. Check out the coax loss calculator I linked. It is very helpful.

As mentioned, nothing will protect against a direct lightning strike. That being said, it is till a good idea to have lightning protection for the near strikes. Plus lightning arrestors will also help prevent damage from static electricity buildup on antennas when everything is properly grounded per NEC codes.

RG-213 has 5.28dB/70% loss at 100 feet and LMR-400 has 2.87dB/48% loss at 100 feet. The calculations were made using 50 watts in and an SWR of 1.5. You can get away with using RG-213 but LMR-400 will definitely work better. Cheaper alternatives to LMR-400 is DX Engineering 400MAX or R&L Electronics Jetstream 400Flex. As @nokones stated, stay away from the cheap stuff from Amazon and eBay. The cheaper stuff will have less ground shielding plus some use aluminum instead of copper shielding. You definitely won't get as good of a solder joint on your connectors with aluminum shielding, if you can even get the solder to stick to it.

My brother didn't request a new call sign either. The FCC will not change it unless you request a vanity call sign.

My brother's call sign stayed the same when he went from technician to general to amateur extra. He was first licensed in 2022.

I found out that the Icom IC-2730 will do the same thing if you have weather alerts turned on. The radio will scan the weather channels every few seconds and cuts out the channel you are listening to. I've never turned on the priority scan feature on my KG-1000G and I made sure to turn the weather alerts off on the IC-2730.

MyGMRS and repeater book are setup so that only the repeater owner or authorized representative are suppose to be able to add, edit, or delete repeaters from the lists. I know with how MYGMRS is setup, if you list someone else's repeater, you will be the one getting any and all requests for access. Both websites require you to acknowledge that you the repeater owner or an authorized representative when you list any repeaters. And yes we all know that anyone can scan and get the tones easily. That still doesn't make it right for someone other than the repeater owner or authorized representative to list said repeater. I know that I would nt care for anyone else listing my repeater on MYGMRS. The reason is that they would start getting all requests. Yes the repeater is open but it is still nice when people do take the time to request permission to use it. It's common courtesy.

Also double check to see what ohms the original speaker is and match it with the new speaker. Most are either 4 ohms or 8 ohms.

Because not all repeater owner's want their repeaters listed for what ever reasons. And it also keeps from have multiple listings for the same repeater on the website. Another thing is if someone besides the owner listed a repeater that requires permission, then the repeater owner will not get any requests at all through MyGMRS.

I doubt that the 712EFC will stand up to 112 MPH winds either. We had winds high enough to blow down a 24-36 inch diameter maple tree on Easter Sunday. The winds were getting close to 70 MPH that day and my vertical antennas sure were dancing around.

The few Tram antennas I have used or setup for others were all easy to tune. And the included instructions are good. I do use a Comet CA-712EFC and it has been a good antenna that has survived several storms with 50MPH + winds without issue.
