Well, it looks like I have to award myself the first nOOb medal in 2024....
The last two simple lines provide the explanation:
sat_list = list(sats.keys())
print (sat_list[:5])
tag = pmt.string_to_symbol("sats")
value = pmt.to_pmt(sat_list)
sats_msg = pmt.cons(tag, value)
self.message_port_pub(pmt.intern('sats'),sats_msg)dec_msg = pmt.to_python(value) print (dec_msg, type(dec_msg)) prints --> ['AO-07', 'UO-11', 'AO-16', 'LO-19', 'AO-27',.......] <class 'list'> The Message Debug block, correctly, show the "values" and NOT the values format. My bad! So, sorry for the noise, I'm going back to my dark cave to dig ....!!!
