Things needed:
A flat screen TV
One of the more expensive radios
A sim with a high handiness skill
Several electrical upgrade parts
Several common upgrade parts
The hardest part of this achievement is getting a sim with a high enough handiness skill. The sims needs to be around level 9 to be able to upgrade the TV and radio with Super Reception. You'll need the electrical parts and the common parts for the upgrades. Once both have been upgrade, have a sim sit down and start switching between all the channels and all the radio stations. I let the sim stay on each channel/station for about 5 seconds. Once the same sims has watched and listened to all the channels/stations, the achievement will pop.
The chef career offers a special channel around level 3 or 4 but I didn't need this for achievement, just the ones that are available after upgrading to Super Reception.
