here is Nelly Ohr's licence
Once you get your licence you can have others operate under licencee's supervision.
So, what would these 2 want to chit chat about rather than use a phone? A radio can be easily turned into a bugging device, or a way to send untraceable SMS messages.
The strange thing is that with all the underhanded stuff going on, why bother with the licence
The FCC call sign is for id only. there are a huge number of frequencies available, SMS texts need to be on the same frequency as the tower to work unless it is going from one radio to another withing a mile or two. Coded transmissions are not allowed by FCC, but a criminal would ignore and use Cheese Pizza, etc as code
Additionally, Nelly might be using the ham radio for surveillance of others such as Security or even other agents
radios may have been used for child/drug trafficking. drop off points, lookouts on the corners for cops, etc
She had a technician class licence. not enough to have a intercontinental connection, it is local in most cases
