some other reason?<
It's known they were pi-L networks because in 2 cases the designer told me, in three other cases, they said so in the published conference papers, and in yet another two cases, the data sheet says they are pi-L networks.

In transmitters specified for load SWR of 2:1 max, what other reason would they have?
Two of the transmitters I'm thinking of had a number  of resistively loaded low VHF tuned circuits too, for parasitic suppression. They didn't have nichrome in them though....
