JAMZ FM

JAMZ FM (also know as 'JAMZ 103' or 'The JAMZ') is the commercial radio station featured in several Grub sketches. The drive show of JAMZ FM is presented by Benno and Dani and know for its 'gotcha' calls. JAMZ 103 features a 'no-repeat workday' (see Episode 1 and Episode 4). 
Dani does a traffic report in Episode 7 for Ocean Squirts keeping remarkably upbeat when describing an horrific car accident. Notably when Benno crosses to Dani for the report he refers to himself as simply 'Ben' instead of 'Benno'.
In Episode 20 Benno and Dani cross to Macca in Aleppo, Syria, who is part of a street team giving away iced coffees.
In Episode 91 an announcer, Fitzy (thought not to be real life NOVA FM announcer Ryan 'Fitzy' Fitzgerald) ran a secret sound competition that Stephanie from Pincher's Burrow guessed correctly. The competition was investigated by Paul Barry from Media Watch after the sound, that of a dog 'growling out its own arsehole' was revealed to be unchanged for at least 13 weeks.
