I'm trying to use the software for the gps and gsm

this links to low filter (not our case) and about the polyphase filter link it doesn't really say what's the tap param about, thx

Can you give me a hand then? We tried to put taps 1,10, etc., but the GPS signal seems to be missing. Could it be that I'm using a too recent computer?

thx

I got a similar issue
`Executing: /usr/bin/python3 -u /home/user/radio/fl2k-examples/GPS/top_block.py

File "/home/user/radio/fl2k-examples/GPS/top_block.py", line 91

SyntaxError: invalid syntax

Done (return code 1)`

I found this helpful information in mail list https://lists.gnu.org/archive/html/discuss-gnuradio/2013-07/msg00084.html
and since I used a newer version of GNU Radio Companion 3.10.4.0 instead of 3.7.12 - the fl2k_transmit_gps.grc file was automatically transformed into the new file format
So I tried to add this value to "taps" variable in the code
taps: '[]'
and it works for me
@pietrondo I guess it would be helpful for you too
