[Hamlib-developer] Python Hamlib - checking for invalid frequency

[Phil <phi...@gm...>]

Thank you for reading this.

How do I check for an invalid frequency or any other errors?

In this example, print(f"Error setting frequency: {error}") is never 
reached.

import Hamlib

rig = Hamlib.Rig(Hamlib.RIG_MODEL_FT991)

rig.set_conf("rig_pathname", "/dev/ttyUSB0")
rig.set_conf("serial_speed", "4800")

rig.open()

#freq = 1.3 * 10000000 # this is a valid frequency
freq = 10.3 * 10000000 # this is an invalid frequency

#ret_code = rig.set_freq(Hamlib.RIG_VFO_A, (freq)) # retcode is always None

try:
     rig.set_freq(Hamlib.RIG_VFO_A, (freq))

except Hamlib.RigError as error:
     print(f"Error setting frequency: {error}")
