I think they deployment in NC is more about connecting to Starlink Nodes and providing broadband

CBRS Spectrum Tier Bands Based on the provided search results, the CBRS spectrum is organized into three tiers, with specific frequency bands allocated to each tier: Tier 1: Incumbent Users 3550-3700 MHz (entire band) - reserved for Incumbent users, including US Military radar systems and satellite services. Tier 2: Priority Access License (PAL) Holders 3550-3650 MHz - allocated for PAL holders, who require a license to operate in this band. Tier 3: General Authorized Access (GAA) Users 3650-3700 MHz - available for GAA users, who do not require a license to operate in this band. GAA users can operate opportunistically on unused Priority Access channels and use any portion of the 3550-3700 MHz band not assigned to a higher tier user. Note that the CBRS spectrum spans 150 MHz, from 3.55 GHz to 3.7 GHz in the United States, as mentioned in one of the search results. However, the specific frequency bands allocated to each tier are as described above.

Citizens Broadband Radio Service US broadcast band CBRS radios operate in the 3.5 GHz band, specifically between 3550 MHz and 3700 MHz, in the United States. This band was allocated by the Federal Communications Commission (FCC) in 2015 for commercial use, with a three-tiered approach to sharing the spectrum among federal and non-federal users. Key Characteristics 150 MHz wide broadcast band Complements Wi-Fi, providing broader coverage, reliable connectivity, and advanced traffic segmentation Suitable for deploying private 5G/LTE networks Supports Wireless Internet Service Providers (WISPs), enterprises, and industries such as utility, energy, manufacturing, and agriculture Use Cases Private 5G/LTE networks for enterprises and industries Wireless broadband services for rural and underserved areas IoT (Internet of Things) applications requiring low-latency, high-reliability connectivity Note: CBRS radios are not to be confused with Citizens Band Radio Service (CB Radio) or other similar services. The Citizens Broadband Radio Service is a distinct allocation of spectrum for commercial use.

I was just reading an article on CBRS (Not GMRS) where they have something similar to ARDEN (Ham Radio) which creates a mesh network to extend internet, wifi 5g and 4g LTE. They are deploying it in NC in the mountains as no license's is required unlike the HAM version of ARDEN. I must confess I didn't know that CBRS had such a freq. allocation. All very interesting.

Just out of curiosity, has anyone tried running this on proxmox virtual server? I have node numbers now and am awaiting interface for vertex 7000, I have a pi4, but I also run various versions of pi on my proxmox server and was thinking to try and virtualize it.

I sent FranktheTank a PM, I think NB700 is now ready to join the alamo network. I did some exstensive testing this past week and I hit the repeater as far away as 50+ miles up north heading towards fredricksburg. It is of course hit mor mis as you move up and down the valleys and hilltops. To the east I can hit it out towards Katy and hit or mis in and around Universtity Texas State., Inside Seguin hit or miss, south of Seguin and good signal.. I have it estimated at 30miles but it is more likely 35-40 on average. That is running it at 28 watts. The repeater is a Vertex 7000U with an internal Duplexer. I have a spare and a 9000 Vertex, just awaiting a duplexer arrival to tune and put it on line for some testing. I didn't want to join until I had everything in place and a working system So I think we are good to go now. It is connected via LMR600 into a COMSPEC DB 408B. I have a few PI4s and just need some directions on connecting. Hopefully soon we will have this area on the network which should great increase our foot print. Cheers everyone.

Hmmm, the only time I had a similar error was when I was using Ce27 version 1.02. I found version 1.08 for windows and that solved my problem.

1. Do the COM ports match what device manager says and what CE27 under config is set for? 2. If they do then I would unplug the cable from windows. Delete the driver reboot. 3 After reboot I would plug the USB cable in and wait for windows to load driver. Once confirmed with COMPORT then plug into Vertex. If that still doesn't work, It could still be a problem with the driver. Some prolific cables have unique drivers. Contact the person whop made your cable and see if he can get you a driver or software for the cable.

OH, and in CE27 you have to go to the config under file (Top left) and select the com port.

Ok just pulled in the drive and headed out to the workshop, wife probably thinks I am crazy! LOL, OK so in windows under device manager as soon as I plug in the USB to RJ45 cable the prolific driver loads and lists a COM port (Mine loads as COM3), I start CE27, and then plug into the VRX, which immediately flashes (Cycles) between CL and on back and forth, I can then download or upload programing as I need. My cable came with a small disk for the driver but windows was able to auto download it one it saw the cable. Hope that helps.

I am using a VRX700 and use windows CE27 with a cable. I do remember that I had to have the correct com port selected for it to read the machine, and if memory serves me I think I had to down load a driver for the cable (Using windows 10). I can verify when I get home and hook the laptop up to it.

When you say worked correctly, are you looking/asking for the wideband/narrow band issue resolution? My understanding is the MXT275 with the original USBA plug cannot be modified for wideband via a firmware update. The USBC model can be sent back and modified for wideband which I just had done recently. My USBA Model works fine but they have low audio on the repeater. The USBC with Wideband enabled has better audio levels on the repeater.

Looks good! I like programmable radios and am a geek with that kind of stuff, but for the rest of the family I have also decided to go Midland because they prefer simple, so that's what we are using in our cars and home. I do wish they would allow us to program them for wideband on the older models. I have returned several MXT275s to be redone for wideband (Assuming they have the USB C) but would be nice if CHIRP would work on them.

You didn't say which radio, but cigarette lighters normal rule of thumb is no more than 8-10 amps.

I got my MXT575, but haven't hooked it up yet as I am still playing with the Wideband version of the MXT275 which was just returned from Midland. I have to say am impressed with Midlands turn-around time on the MXT275. Optimally it would be nice if we could just do it with Chirp.
