Right now, the Tulsa MeshCore network is pretty sparse. Additionally, the defaults for MeshCore are more aligned with Meshtastic's ShortFast settings, so direct line of sight is even more important. 

If you have direct LoS with the BOK Tower, you should be able to use the "discover repeaters" feature (3-dot menu, tools, discover nearby nodes, discover repeaters) to find that node. You can also add it from the Internet map, then try and ping it.

Not sure if the broader group is aware, but my server has MT 903 nodes. The developers have been adding Meshcore Support recently. If there is interest I can flash a node to MC for visibility.

i looked and matched mine to the one at city hall. im in brookside closer to 51st and tried at 41st and i44 and tulsa hills. i might head down and get closer. have another heltec v3 i found but missing antenna so i think ill flash it when i get an antenna tomorrow and see if the two nodes communicate. thank you

[Phillip Ramirez]

im going to head down later and see if i can get the repeater . thank you

906.875 is the standard for slot 20, I think.  Long/fast is the default most use.

I dont know a whole lot about this, but that jumped out to me.
