SteveShannon reacted to WRYZ926 in Storm chasing using mobile GMRS?
All the Sky Warn Nets (weather reporting) are normally done on local 2m repeaters. That's not to say a local group could not run a Sky Warn Net on GMRS as long as the repeater owner is okay with it and you have people that can report directly to the NWS.
We do not use our GMRS repeater for Sky Warn Nets but most of us do monitor it just incase during severe storms. We were asked about running a Sky Warn Net on GMRS but that would take away from our 2m Sky Warn Net as we are only allowed so many people that can actually report directly to the NWS. We don't have enough people that can report to the NWS to run two nets at the same time.

SteveShannon got a reaction from WRTC928 in Retrevis FRS 22 not talking to other brands
The logical assumption is that there’s are CTCSS tones or DTCSS codes somewhere that you don’t realize are there, either on the FRS radio or on your other friends radios, or the radio is transmitting on frequencies the other radios are not receiving. We can’t really know for sure without more information, such as you posting a screenshot, a chirp file, maybe a device like the SW102 showing the output power and actual frequencies of the transmissions that others are not receiving. But we can speculate a bunch:
Bad programming.
Bad firmware.
Both.
But here’s something to try. When it’s transmitting and other people’s radios don’t seem to receive it, put your UV5R into “scan for tones” mode to see if it’s actually sending with a tone that the other radios filter out.

SteveShannon got a reaction from WRUU653 in Any mobile radios that do 2 Watt FRS TX/RX?
Manufacturers could design mobile radios to put out half a watt, but because FRS regulations require handheld radios and because GMRS regulations limit 8-14 to handheld radios, mobile radios could not be certified, even if they complied with the output power requirements.

His request doesn’t make sense. Any GMRS mobile radio will talk to FRS radios except for channels 8-14 which may only be handheld portable units by regulation. GMRS handheld radios can talk on 8-14.

SteveShannon reacted to marcspaz in BuyTwoWay came up with a CW solution for KG1000 Radios
@WRUE951 that sounds good. I'm glad you've had good luck with them. My experience isn't terrible, just not ideal results. Since most of mine are EmComm related, I never really ran one for more than a few days at a time, and mostly left them off until I/we need to use them.
I know what you mean about learning the hard way. I struggled so much to avoid spending the money on a proper repeater that I probably spent 3 or 4 times more than if I just went for a regular repeater to start. I finally built a full-blown potable repeater system... it can do 2m, 70cm, crossband or act as a base station. It has a built-in 50 amp hr battery system and can run on solar or AC. Retail, it is about $17k to build, but thankfully some stuff was donated and I was able to get great deals on a used repeater and commercial VHF duplexer, which cut the cost down to about 10% of new/retail.

I started out with a KG1000 repeater and never had issues other than desense early on. A couple times a year the repeater got pretty heavy use during nearby off roading events. Yea, they do get hot, but they keep on ticking. I use two Maxons for a portable repeater, they never break a sweat and they are housed in a ventilated ammo can. Now my current Hytera Repeater can run 24/7 with no worries. Amazingly, I paid not to much more for the Hytera radio then the two KG1000’s. I think we all do this, we learn the hard way.

I think it's great that they came up a solution, and as much as I love the KG-UV980P hardware platform, I would never use a KG-1000 nor a KG-UV980P as a full-time unattended repeater.
1.) As good as they are, they are not designed for continuous duty cycles or 24/7 operation.
2.) They may overheat or flat out fail with prolonged use.
3.) The transmit/receive isolation is not as good as a proper repeater, leading to desense issues.
4.) Audio quality and levels can be inconsistent.
5.) VOX or Carrier Operated Switching methods can introduce delays, distortions, and clipping.
6.) There is zero remote monitoring, diagnostics, or telemetry unless you engineer something yourself.
7.) Paired mobiles are extremely inefficient with regard to power consumption.
The only time I ever have or ever would use paired radios as a repeater would be for temporary field use and as an emergency backup (maybe). In an emergency, the FCC isn't going to ding anyone for not having the repeater ID on it's own, and for temporary field use the control operator is IDing the repeater every time they ID themselves... so an add-on device is really not needed.

I received the same email. I want to do some more research to see if they will ID every 15 minutes 24/7 or if it can be set so that it only IDs every 15 minutes when there is actual traffic on the repeater,

SteveShannon reacted to OffRoaderX in Retrevis FRS 22 not talking to other brands
The bandwidth setting has nothing to do with your issue.
Either there are tones on the radio that cannot 'hear', or the two radios are too close to each other when transmitting.

SteveShannon reacted to OffRoaderX in Unlocked UV-5G?
I like either the AR-5RM or the XTS5000, depending on how many monies you want to blow and how strongly your radio-dork gene is presenting.

SteveShannon reacted to Lscott in Duplexer Tuning Question
The simple explanation is one is used to isolate the transmitter from the receiver. Since the repeater is a full duplex operation, transmit and receives at the same time, any RF energy from the transmitter will get into the receiver. When this happens the receiver will trigger the transmitter. Now you have a feedback loop where the system will stay locked up on transmit until the power is yanked, destruction of the receiver's input at worse, or simply kills the sensitivity of the receiver then it becomes deaf to weak signals.
The typical notch/bandpass duplexer filter is setup such that the receive half of the filter is tuned to notch out the transmitter's frequency as much as possible. The bandpass filter on the transmitter side is tuned to eliminate as much of a spurious signals that are not on the exact transmitter's frequency, thus preventing them from entering the receiver's circuits.
For the above to work a certain frequency minimum difference between the transmit and receive frequencies are required. This minimum depends on the quality (design) of the duplexer.

SteveShannon reacted to Lscott in Could FM CB supplant FRS?
At least on the official side. My buddy has his "export" mobile radio for 12/11/10 meters. He's run FM on 11M with a few people, and that's before the FCC allowed it.
The question will it replace FRS. I think the answer is no. Why. The usage cases are different. People using FRS have short range communications requirements. The small size, radio plus antenna, fit in a shirt pocket or on a belt very easily. Anyone that's looked at some of the older "HT" style CB radio, well they're about the size of the old WWII walkies-talkies. The antennas for any reasonable radiation efficiency are ridiculously huge. These radios are not convenient to use.
The retired cop in my radio coffee group tells us stories how the older Motorola radios were not liked that well. They were large, bulky and the officers complained about the antennas poking them in the armpits all the time with the radio on their utility belt.

SteveShannon reacted to WRYZ926 in GMRS for LA Riots.
SOP hasn't changed, one still has to keep transmissions short to keep the enemy from triangulating your location.
The Russians and Ukrainians are finding that out the hard way. Difference is you now have to worry about drones along with missiles and artillery. Signals are scrambled and most military radios use frequency hopping but the can still be located if they transmit too long.

SteveShannon reacted to rdunajewski in Unable to register - say my license could not be found eventhough I have one
There is an issue with the data we receive from the FCC, which affects newer licenses. We worked around it and have processed all the available GMRS licenses that we can see through the FCC data export.
If your license was issued in the last 48 hours, you should be good to go now!
