For the time being we only support Stripe as a payment processor for credit and debit cards. PayPal is supported for making club payments and receiving payouts if you're a paid club owner, but that's because it's a separate system. Since all payment details are handled by Stripe directly, we don't store your card information in our system. Stripe is the leading payment processor and powers many credit card payment platforms including Shopify stores, like our online shop. This is the most secure method to handle payments in a PCI-compliant way.

You have to delete the repeater. Adding a listing to the database makes you the owner, and requests will go to you. If you are NOT the owner, do not list the repeater without the owner's consent. Remove it from the "Owned Repeaters" tab of this page: https://mygmrs.com/profile/repeaters

Honestly, I'd be surprised if this got FCC approval. Actually, scratch that, the RT10 got FCC approval and I'm confident that is not legal for 900 MHz at 1W as license-free DMR. Pretty sure that squeaked by and so might this little gem.

Meshtastic also supports voice using Codec 2 on LoRa but only on 2.4 GHz radios due to the bandwidth constraints. That's what makes audio on UHF interesting. https://meshtastic.org/docs/configuration/module/audio/

The little "repeater" is also interesting, and solar charging capable with a built-in battery backup. https://www.retevis.com/rb91-direct-frequency-digital-repeater-with-2pcs-rb24-uhf-handheld-radio-us

Well that's interesting, it claims to be a LoRa radio in the UHF spectrum with 5W of power.

A week is a pretty good turnaround...

They are skipped during scan by default since there's no output tone. Any activity on the channel will cause the scan to stop and what you're hearing may or may not be that repeater anyway. This way, if you get the tone information, you already have the channel programmed, you can set up the tones and add to the scan list, and you're off to the races.

You can now download a Google Earth KML file for each state from the Reports page. Please let me know if you have any feedback!

I've been tinkering with these as well over the last month. Just driving around with the antenna inside the car I got 1.9 miles through dense suburban terrain. I've had a full conversation with someone about 1.5 miles away with the antenna inside the house near a window. It doesn't appear to be busy here in NJ, but I do see a couple nodes pop up here and there. Thinking about attaching a node to a drone and getting it 400 ft up for about half an hour and see what I get. I also set up an MQTT server for linking my mesh with my father who is about 25 miles north of me, and that works well also. You can't really use the public MQTT server because it will completely flood your mesh and probably lock up your devices from all the traffic, so be careful with that. If anyone is interested I can create a channel on the server to tinker around with.

I'm listening on Chrome on Windows right now to 169 Midwest Hub, and it's working fine.

I refreshed your account status, and it now shows you as a Premium Member. Thanks for your support!

When gaps occur in the FCC database files, you won't show up until the following Sunday's full database update. The FCC publishes a weekly full database file, and then during the week they publish the new and updated licenses incrementally (known as deltas). If their system doesn't generate a daily file and your callsign would have been in that day's file, you won't appear in the next daily file -- you'd show up in the next weekly full database file. It's a pretty antiquated system, but it works most of the time. The biggest issue is waiting until the next day for us to learn about new licenses. The FCC created an API that allows live lookups, but it's painfully slow and practically unusable. It's easier to download the database updates and host the data in-house.
