I too posted a similar issue with my F9P on the EEVBlog with the exact same
results as you are having. I still don't have an answer for the satellites
not showing up in LH.

Afternoon all,

I finally got ahold of a UBlox F9T in the form of the RCB-F9T evaluation
module.

Got it talking to Lady Heather on an old Raspberry Pi, and everything is
working, but the satellite table is blank.  Just shows ".." in the PRN
column, with AZ, EL, SIG, and DOPPLER blank.

Clearly, she's tracking satellites, as the "Tracking sats" message is on and
the 1PPS LED is in phase with all the others here.

I've been searching thru old posts, the manual, EEVBlog webpage, pretty much
any place that has Lady Heather information...and can't figure out what I'm
doing wrong.

Anyone know what I might be doing wrong?  I am using the /rxu switch, have
tried toggling different GNSS systems on and off, all with no effect...

When I connect the unit to my PC with uCenter, I can see satellite
information just fine...

thanks much and 73,
ben, kd5byb
