More specific to GMRS is this paragraph: 95.1761 GMRS transmitter certification. (a) Each GMRS transmitter (a transmitter that operates or is intended to operate in the GMRS) must be certified in accordance with this subpart and part 2 of this chapter. (b) A grant of equipment certification for the GMRS will not be issued for any GMRS transmitter type that fails to comply with the applicable rules in this subpart. (c) No GMRS transmitter will be certified for use in the GMRS if it is equipped with a frequency capability not listed in § 95.1763, unless such transmitter is also certified for use in another radio service for which the frequency is authorized and for which certification is also required. No GMRS transmitter will be certified for use in the GMRS if it is equipped with the capabilities to operate in services that do not require equipment certification, such as the Amateur Radio Service. All frequency determining circuitry (including crystals) and programming controls in each GMRS transmitter must be internal to the transmitter and must not be accessible from the exterior of the transmitter operating panel or from the exterior of the transmitter enclosure. (d) Effective December 27, 2017, the Commission will no longer issue a grant of equipment authorization for hand-held portable unit transmitter types under both this subpart (GMRS) and subpart B of this part (FRS). (e) Effective December 27, 2017, the Commission will no longer issue a grant of equipment authorization under this subpart (GMRS) for hand-held portable units if such units meet the requirements to be certified under subpart B of this part (FRS).

Why did you quote only 95.335? One of your questions is addressed in 95.337

You'll get a lot of different opinions here. My interpretation of the regs is that if a user changes the way the radio is configured/programmed in order to allow transmit on non-GMRS frequencies then the radio's certification is void, There's an epidemic of rule breaking in GMRS including some of the most prolific posters here. I tell people what the rules are but I don't report anyone, at least so far.

Radio specs are submitted by the manufacturer to the FCC and the FCC issues a certification. Look and see if the radio has been certified. A certification identifier should appear on a label attached to the radio. However, you’ll soon learn that as long as you make any attempt whatsoever at following the rules the FCC will never know or care.

Sorry if this topic has been hashed out before on this forum...I didn't see it after looking through old posts. Is it or isn't it FCC non compliant to utilize a GMRS radio (for GMRS) that is "unlocked" to manipulate the pre programmed GMRS frequencies or other pre programmed settings? I have read through Part 95 and only find part 2, subpart J that seem to discuss the matter (all above my head) but seems to be aimed at the programming and software installed by the manufacturer. Here is the real question...is my Baofeng UV-5RM, which came loaded (but not locked) with the 14 GMRS interstitial channels and the 8 GMRS main channels (but no main repeater channels), apparently sold to be a GMRS radio, FCC compliant to be used for GMRS? Reading through Part 95 makes it sound as if you need to be only compliant to how your frequencies, offsets, tones, power, etc... are programmed. Seems to me as long as it's programmed/used to be FCC compliant, you should be good. Am I wrong or does the FCC really say I can't use a GMRS radio unless the manufacturer programmed and locked it to FCC standards?

Just get the same size screws from the bins at Ace, Home Depot, or Lowe’s. Because the old screws already tapped the threads you no longer need self-tappers.

You can always get them from McMaster but in these sizes you have to buy 50 or 100. https://www.mcmaster.com/products/screws/thread-size~m2/length~16-mm/drive-style~phillips/?s=2mm+screws Have you tried your local hardware store, I'm quite sure they'd have them.

Nice! I bought a '97 tj in November. Its going through factory rehab right now. Going to be all original.

I'm well aware how SINCGARS works since I used the system when I was in the Army. One still has to input the security keys every 12-24 hours depending on SOP.

Ok, so not all encryption is compatible between manufacturers. I'll give a common example. Both Kenwood and Motorola had DMR radios, but their "basic" privacy is not compatible between the two. Motorola's is a 16bit XOR, Kenwood's is a bit different, thus incompatible. The "basic" privacy is typically a non-standardized encryption that is for basic privacy at little/no cost. Now, you can use Enhanced Privacy/Enhanced Encryption in Moto/Kenwood DMR, because they use a standard, ARC4/RC4 40bit encryption. Same goes for other standard methods of encryption such as DES (64bit) and AES256 (256bit) which is compatible between manufacturers, as secure interoperability is required. These methods of encryption can be used with NXDN and P25, based on options available (both cost and free) for each radio. Loading encryption, when meeting opsec/FIPS requirements, creates the key, which is stored in either a hardware or software vault, and then loaded into the radio via manufacturer specific software, or with a hardware device called a keyloader. The keys can be transferred between secure devices (keyloaders/vaults) but after creating and storing them, you can never view what the key is again, so store it properly. In the case of many of these Chinese radios, security and standards are typically not followed. You basically copy the key into the software, apply it to the digital channel desired and that's it. Keep in mind, since they don't follow the standards, the encryption may not be compatible with others. The AES could be AES128, or just a completely made up 256 encryption method applied to DMR different than the standard, thus not compatible with other radios using industry standards. @WRYZ926SINCGARS uses frequency hopping for security, which not only doesn't show up on a scanner/close call, it's impossible to follow without the starting frequency and hop-set, which is why it's just as secure as AES, if not more.

you never know.. it's good to have a couple radios around set up for encryption. The Baofeng approach is nice because most people will not shell out hundreds of dollars to have the option. Each person in our camping group has this radio ordered up. I ordered mine from Radioditty and have gotten two shipping delay notices.. Couple of friends ordered direct from Baofeng and they also recieved delay notices.. A lot of folks must be ordering this radio.

As of today, the K61 is about $19 and the 5RM is about $23 on Amazon, so for most people, the cost won't be a major factor unless they're going to buy several. The 5RM is a heckuva lot of radio for the price, but since I got a UV-5RH Pro GPS, I don't use it much. If I'm going to carry the radio a lot, I take the K61 and if I don't plan to carry it much, I use the 5RH. Plus, my K61 is green, which is really cool.

Thanks for the help guys. What I don't understand is what WSBB said in regards to encryption working on the DM32 HT but not with other brands. I thought if an HT has AES256 encryption capabilities then the radios should communicate, regardless of brand, as long as the encryption key is identical. Help me understand that if you could, please (might take a few tries with me)? Also, I see videos of a guy in a face covering showing how to type in random characters in the programming software for a TYT ht to encrypt that radio. What I get confused about is that I see anyone can google AES256 key generator but once that spits out a key does one just copy and paste that random set of characters into the encryption field on the radio programming software for all the radios? And then where I get confused is sometimes I read that you need a key loader to do this, making me think it's not a simple copy and paste operation? Just trying to understand encryption better.

I always used either 6" or 12" numbers when using a hand held in vehicles. I use to run a hand held CB radio with an external antenna for a while back in the early to mid 90's. Adding another 6-12 inches of RG58 to the antenna coax won't hurt. Most mag mounts use between 13 and 15 feet of RG58 on average. I have SMA to BNC adaptors for when I want to use my hand held with my portable yagi or faraday cloth j pole antennas. Having a box full of adaptors comes in handy.

I've standardized on BNC wherever possible. You can usually find and adapter for some weird RF port to a BNC. For example I have a few Icom HT's that use a rather strange port. I had to special order adapters so I could use an external antenna with them. https://forums.mygmrs.com/gallery/image/500-ic-f3162dt-front-and-back-sidepng/?context=new BNC jumper cables are easy to find. As long as they are kept short the usual RG-58 coax doesn't cause much of a loss.

The radio i use in the secondary vehicle has a BNC installed on it, the rest of my radios all basically have a single use in mind, so the antenna stays put most of the time...

Yea, I keep responding to your calls for a signal report here in SC on my "very ole" Midland 500 but you can't seem to hear my reply. Maybe a better antenna would help... (:>)

I was around for the demise of the CB call numbers while living in Hawaii. As users would drop their call call signs people that had many friends began making up call signs for their group with corresponding numbers like family members. Ours was "KMA-1??." So, for some time, we had either a real ID or a fake to use depending on whom you were conversing with... Lots of fun with rabbit chases too... Good ole days.

The NotARubicon approves!

@WSJH655 welcome to GMRS. Lots of fun and good information here.

I was using a DTMF switch that required an HT transceiver to remotely shut down my repeater. It worked but wasn't always reliable. One of my friends told me about an eWELink WiFi switch he uses for his garage door opener that works off a free eWelink phone app.. (both androoid & IOS). I bought one on Amazon along with a fused 30A relay. All together $12 bucks. Tested it out on the bench, works great. I can shut down the repeater anywhere in the world and it's pretty much 100% reliable.. Just got done printing up a case to hold it all.. thought i would share for anyone looking for an easy solution.. If you want the 3D box print... message me, i'll send it to youl. The eWeLink switches come in a one Ch, two Ch or 4 Ch DC configurations. i used their 'one Ch.' for this project. IMG_3172.HEIC

Wouxun KG-1000G question: Does anyone know of a source for the 2mm self tapping screws used install the front panel onto the inclined switchboard channel or the flat switchboard channel. The flat panel uses 11 mm long screws and the inclined panel uses 16 mm long screws.

I’ve reported your post to the owner. He’s the only person who can help.

I love this app once you get in, it is hard to use. Been two days and only made into here, I think I need to have someone delete my account as I’ve never found the delete button and start over. Please make it easier. Vickie
