can't read itron cl200 c1sr (fcc sk9c1a-3b) #297

thank you for this software. i can't seem to get a read on this electric type 7 meter itron cl200 c1sr (fcc sk9c1a-3b)

since you mention c1sr should work i'm wondering if not all c1sr are equal.

doing some searching i found "Operates using spread spectrum technology" so i wonder if it's a different protocol altogether.

this reddit post https://www.reddit.com/r/RTLSDR/comments/10fsj93/reading_itron_ert_scm_data_help although not for the same exact model suggests it may be transmitting using cellnet technology so I may be experiencing the same issue.

FCC https://fcc.io/SK9C1A-3B says this operates within 909.6 - 921.8 mhz. Is there anything I can do to confirm whether I am using rtlamr correctly? I am not passing any parameters to rtl_tcp or rtlamr

perhaps there is some hope. i used rtl_433 -f 912M and just saw my meter. I tried this yesterday but no luck. maybe it's not transmitting frequently?

it transmitted twice between 4 minutes although didn't see any readings at the third set. is there any special parameter i should use with rtlamr or i just got lucky?
