Conduit Setting Frequency SubBand : 2 has the following channels.
This should match your uplink channels.
Index Frequency DR Max Min On
0 903900000 3 0 1
1 904100000 3 0 1
2 904300000 3 0 1
3 904500000 3 0 1
4 904700000 3 0 1
5 904900000 3 0 1
6 905100000 3 0 1
7 905300000 3 0 1
U 904600000 4 4 1
R2 923300000 8 8
The first receive window will depend on uplink channel.
RX1 – 0,923.3; 1,923.9; 2,924.5; 3,925.1; 4,925.7; 5,926.3; 6,926.9; 7,927.5;
Default RX2 – 923.3 DR8
These appear to be misspellings, but looking at other examples they appear to be correct for the library.

Have a look at this project, it appears to setup the channels differently.
Setting to US915 hybrid should initialize the tx and rx channels.

I don’t know what frequencies will be set for hybrid on the end-device, you may want to experiment with Frequency SubBand settings on the Conduit. I would try first with 1 and then 2.
There are a few other projects to look at on github as well.
