It wouldn't matter if it is certified for gmrs when listening. The Baofeng gmrs v1 hears it as well. It's more of trying to find the offending source of the rfi. Sent from my SM-G975U using Tapatalk

Will try without the antenna. Only the gmrs frequencies. 70cm seams to be clear of the issue. Bounces around also so a chore to chase down. Sometimes on channel 4 then channel 6 then it will be on 19 or 22. Killing me. Can be heard outside of the vehichle also with the radios. Probably one of the modules probably a pwm module failing.

The Burb decided to become damn near dangerous to drive. Most of the possibilities for repair were going to cost what I paid for the truck. So I gave up on her. Enter 200 Land Cruiser. Got the FTM 400 installed. However, on GMRS frequencies I get hash. Even with squelch all the way up it breaks the squelch. So far with the engine off all accessories on no hash. Engine running is when it occurs. I even took out the BF8hp and can hear it when the engine is running and all the ham gear (radio, power pole distribution and Cell phone chargers unplugged). Was trying to use the BF8HP as a locator but eh probably not the best radio for it. So the noise is not entering through the power leads, since it can be heard by the Baofeng. Kinda, lost as where to go to find the source of this noise. Never thought I would have to do a fox hunt on my truck. Any suggestions.

From ehat I can tell there is a repeater on 19 in nova. Alexandria I think. Haven't been able to get the repeater I'd, apparently its been running for a long time. I catch it college park, MD. Lots of picket fencing in the truck. Much stronger in Rockville Md. Sent from my SM-G975U using Tapatalk

From my reading of the law. You can't even have it in the car/truck. Due to the fact some of those frequencies are used by their lmr and public services. I am ham. They really don't question my gear my ham gear. I do have an sd card for my FTM400 that has all the gmrs frequencies removed to avoid any temptations Sent from my SM-G975U using Tapatalk

The concept has existed, well in the Ham world. Repeaterbook. Although Repeaterbook's app doesn't really have a gmrs filter and the website database is meh. I applaud your effort, it is an app that we needed. 3 problems. 1: what if the repeater is REACT or club member only? 2: not all Gmrs repeaters are available for general public usage? 3: how to restrict people without a gmrs license to access the info?

Tropho ducting rocks. I want to experience sporadic e, I can't tell the difference unfortunately. Sent from my SM-G975U using Tapatalk

Using stock, design the enclosure so everything was inside of 12" of each other. Did you check to see if you have loose power connections? Also make sure to run the firmware updates before install. I have been having issues with aprs, sometimes doesn't beacon. I see the packet in aprsdroid, just not on aprs.fi. starting to think it maybe a GPS lock issue on cold start. The tarheel is what I had looked at for hf. Just with the controller and the antenna it would cost almost as much as say a ft917. So we'll outside of my budget especially as a tech with no hf privelages. Would love a scorpion antenna, actually may die for one..... Sent from my SM-G975U using Tapatalk

Got a Wilson 4" flex, it is too long to 10m. So in the back of the truck is a Shark 10m (non-mini) little shorter then the MFJ, still gotta tune it. Been working on a 2012 JKU Unlimited Wrangler, my dad picked up. Absolute garbage, well this example is. All the common crap. He made a big mistake buying this and knows it. Just keeps apologizing to me. For example, stereotypical overheating on the 3.6L. Welp wish that was it, but to give an idea spent 9 hours pulling wire and correcting a bunch of hokey stuff on the truck. YSF/C4FM is just another digital format, it is very similar to P25. There is a narrow band and a wide band digital format. Both are too wide to be used on HF say like a 991a, hence. Dstar is narrow enough to be used on HF. The FTM 400 when put in AMS mode, will auto select Fusion digital narrow, Fusion digital wide, FM narrow or FM wide based on the signal it receives, now you see where the C4FM nomenclature comes from. Wire-x is the when the repeater or radio (PDN) is connected to the internet and can access the Wires-x network. FTM400 when set to PDN mode say in a base station setup with internet access can act as a portal to the WIRES-X network. You will need another C4FM capable radio to connect to the FTM-400. Otherwise you will need a hotspot, which connects to a bridge. Keep in mind the Bridged "Amerilink" room is not the same room as the one on the Wires-X/Yaesu network. Confusing, yup.... Then there is GM "group monitor" You can set an ID and Group# beacon on a frequency and anyone close enough by with the same group # in GM mode will popup on your radio. By default it is set to ID 0 Group 0. No one in my area is really on GM on the FTM400 or my FT991a on 6m. One of my HAM friends (collects radios) says that C4FM/Fusion wide sound the best out of all the digital modes. With P25 and DMR sounding pretty good. Pretty much said all of them on narrow mode sound like garbage. You know the nasal under water robot sound. Check to see what Wire-x or Fusion repeaters are close by. That may sway your decision by a big long shot. Especially, since a lot of higher end DMR radios come with APRS. I'll try to get a shot of APRS Droid and the FTM running to give you an idea of what I was going for. As well as what Americalink sounds like over the repeater. Hell may do it on the FT991a and HRI so you hear what it sounds like.

Its through APRS... For Winlink and FTM400 For APRS FOR SMSGATE

Part of the reason I eneded up with the 400, was the ability to do Winlink, and SMSgate via the touch screen. Didn't like the whole T9 style texting of the Kenwood. Would of ended up with the ID5100a if it weren't for DPRS, yes you can add a TNC, but was trying to avoid that. Also, wanted to avoid a laptop in the computer, the boot up time was a big one. I did however, wanted to see resource location

The TNC on the FTM400, is limited. It was more for visual representation on a map using APRSDROID, with a cell phone, as well as using APRDROID it is easier to see the raw aprs packets data, which is a pain in the but on the FTM 400. Not sure if it will relay SMGATE/winslink data from the phone to the radio. READ: NO digipeater possibilities in stock format. If you need full packet control you can add a TNC, and bypass the onboard TNC. However, at that point I would recommend a Kenwood 710ga, which has a fully accessible TNC, and a windows laptop. You could do pretty much the same thing incorporating a Bluetooth dongle. The FTM400, from what I get doesn't follow all the standard APRS formatting either, think it was a weird nemea data.

Yup, there is actually a lot of traffic, especially by big highways. Makes 10meters look like a barren waste land. Guess most people's antenna setups aren't good. With the Wilson flex (4ft), I hear less then with the hamstick. Got a shark 10m antenna ( full size not the min) it's a tad short then the MFJ, also a lot thinner. Whip is much thicker. I will report back in when I get the chance to test it. Sent from my SM-G975U using Tapatalk

Funny enough swapping to a 10m hamstick netted 1:1.12. Well till it fell off on the highway and got run over.. now it is a bit higher. Lol Sent from my SM-G975U using Tapatalk

Current update. This morning on the way to work the antenna and 1/2 the nmo decided to divorce me on the highway. It went flying off and promptly got destroyed by the car following me. So new mount for further down the 1/4 panel, going to use the 5/8ths fire ring mount.

Water jet to cut precise lines. You could mock one up in Autocad and 3d print it? Realistically, probably going to be a hole saw with a jig saw. Slowly so it doesn't melt. The fumes are not so good to you. Maybe mount the things to acrylic and place it in the enclosure. Sent from my SM-G975U using Tapatalk

First off welcome and congrats. This is going by the p.o. box listed on the fcc uls database. The one in Pittsville/Willard (about 50 miles) is noted as local use. Until it is mounted to a higher up. You are fortunate the eastern shore is flat. With some elevation ( on a tower) and a high gain antenna when it is mounted to a tower, you may be able to hit it. Annapolis one is about 36.32. Depending on the height of the two repeaters antennas. Probably your best bet (since the open water doesn't block transmissions). May also get some local trophosperic ducting across the water. Just because it isn't listed doesn't mean there aren't any repeaters close by. So spend some time listening to the repeater channels. Use the forum map to tryvand contact the owners of the repeaters. They may be able to give you an idea of height of their antennas and expected coverage. Otherwise, 2 options. 1.) You are limited to local coms unless you get a ham ticket, bit more ham repeaters not huge amount. 2.) Time to start saving up and learning how to build your own repeater. Also, a yagi up at least 30 feet pointed to the repeaters maybe able to hit it. But generally, you will have to mod and tune an amateur one for gmrs. What do you have or plan on getting?

I think every one us wonder to whom this is directed to. Ic9700 is awesome for sattelite work at home. Probably for me: Ic9700 for upper band work and dstar. - mm bandwidth compatibility - may work with the newer aredn meshes Flex 6400m for hf work. - really digging the maestro ( hf work from the bathroom you know) Open spot 3 for a hotspot - cheap Chinese dmr for the portable connection -crossband while roaming the house. Yaesu ftm300 for yaesu wirex and alternate 2m/70cm radio. - the flexibility of pdn mode or rf work - dual c4fm (semi permanent beacon on one side) Sent from my SM-G975U using Tapatalk

One big negative to the ft991a is that it is too old and lacks the hardware to be used as a pdn. Nor can it connect to the HRI 200. There is a difference between a wire-x repeaters and fusion repeater. Wire-x you have internet access to most rooms. Fusion just another digital mode. The fusion/wire-x repeaters are still being sold at a heavy discount, as long as it is activated in a certain time period. For small ham clubs, it makes a huge difference when upgrading aging repeaters or wanting to put up a digital repeaters. It is why you still see moe and more of them, especially in rural areas. Join the 10m c4fm group on Facebook and watch videos. Especially, if you have a good 10m antenna. I have another post where I got a catzknob for my ft991a. It is awesome because you can assign functions to them instead of digging through the soft menu, basically may free up some of the onscreen quick menu buttons. 2 negatives. 1.) The eprom can only be written to 100,000 times. Which means you may want to be choosey with what to assign them. 2.) Everytime I power everything up and touch a know it reverts to the minus setting. So if you set squelch, then turn it to say 6. Power off and back on the squelch will be 0. Also some functions like noise blanker which has an off. The know does nothing till you touch the soft menu from "off" to "1". Awesome radio either way. Sent from my SM-G975U using Tapatalk

My input, all my opinions. I chose fusion. Why? At the time all the DStar radios (this was for mobile) only did DPRS. If Kenwood had made an updated 710ga that did DStar and APRS. I would probably be a DStar man. There are more DStar repeaters in my area then Fusion, DMR, and amateur P25. I looked at the DMR. One thing I didn't like was first you have to pick a group then a time slot. I understand the principles of DMR but it seamed like it would be harder to reach out and talk to more people some one (multiple branches so to speak). Plus if it isn't in the code plug have fun trying to program it on the fly. Yaesu's Wires-x is interesting. For example Americalink one of the biggest rooms can be accessed via HRI200 (in my case analog mode), a Yaesu radio that supports PDN node mode, or a linked repeater. If you came over a HotSpot, say with a DMR radio and a hotspot, it isn't the actual Americalink room, but a bridge room. So using Droidstar, I love having the HRI-200 up, the FT991a connected to a repeater and during the Net on Americalink. Because the FT991a can hear the conversations the HRI-200 can hear it but since Droidstar is coming across the bride, you get NADDDAAA. If you did get a hotspot, highly recommend, you only gain more with the handheld or mobile unit. The only one that can really do cross mode to DSTAR properly, is the SharkRF Open Spot 3, $$$$$. All the others don't do it due to the lack of the second AMBE chip, from what I understand. Also I had a conversation with a big RADIO guy ham. A friend of a friend were met up to exchange gear. He said personally, Yaesu C4FM/Wire-x is the most natural sounding and cleanrist, especially on WIDE digital mode. On narrow digital mode, it can get the same robo sound of the other digital modes. He has a DStar, C4FM, DMR, P25 and NXDN radios, hand helds, mobile and base stations. Plus a DMR repeater at this house. His choice was C4FM, P25 then the others. He kept asking me why DStar, when I was picking his mind. So that wasn't a positive. From what he and I could tell more people were on C4FM then DMR when just roaming about. DMR can be a bit sparse out in the countryside, where you are most likely to find a DStar repeater, a little less frequent is a C4FM. Really, wish someone would could come up with some type of cross protocol platform outside of the hot spot. The different digital modes have us so fragmented now. Really going to come down to what repeaters support what mode and what the locals are using. Especially, if you aren't going to do a hot spot. If I were to buy an Open spot 3, I'd probably pick up a DMR radio. Especially, since it seams the early ones were developed for DMR. Then C4FM being added as well as DStar.

Yup less the 6 inches for the tuning tip from 10m (28.400) to mid point for 11m. Just tuned and marked the whip. Even then it's about 1.8 when half way between the marks for both band edges. Sent from my SM-G975U using Tapatalk

Found some photos looks like a mish-mash of the 400. Is it me or does the body of the radio look like the body of a Yaesu FTM400? Looks like it is going to be a great radio. Available 25khx spacing. Testing showing 49.x Watts (manufacturer cushion to allow for tolerance variations). Looks very spectral clean with almost no spurious emissions. My only gripe "hi and lo" power settings from what I can see in the manual. So you get 5w or 50w, wouldn't a medium of 15-20w power setting been nice? don't like running radios at full power unless I need to. https://fccid.io/MMAXT575/External-Photos/Ext-Photos-5212922 https://fccid.io/MMAMXT575

Hope you guys had a great father's day. The girls went a bit nuts this time around. Here are some of the pics of the gifts, most were ham related. Didn't bother with pics of all the stuff. Wish I had a pic of the Custom have cave sign.

Get two for sota/pota work and look at running it as a dipole.

Yup. Too bad my random wire blows for 6m. I could get out so far was about 10miles. Picked up a dxcommander, need to build it. I am hoping I can have it setup so I can catch the early band openings. Random wire did get out to Tenessee a couple of weeks ago during a 10m opening. Did it on Olde 28.400 ssb. Sent from my SM-G975U using Tapatalk
