Preston G4 wireless board upgrade compatibility and performance issues
16 years old. Gear and prices may have changed since.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- The G4 upgrade replaces transceiver boards with new hardware operating on different frequencies to reduce interference on crowded 2.4 GHz bands, costing $450 per wireless component.
- G4 boards are not backward-compatible with older components, requiring a complete system upgrade and preventing mixing old and new devices.
- The upgrade applies to HU3 handsets, MDR2, Radio Microforce, F/I handset, and V/F receiver, but older HU2 handsets cannot be upgraded.
- HU3 handsets report experiencing intermittent interference and iris control transients in some locations despite the G4 upgrade being designed to reduce these issues.
- HU2 handsets operated reliably on 2.4 GHz with some users reporting fewer problems than newer HU3 units in busy RF environments.
- Microforce units received a separate firmware upgrade enabling programmable soft stops and feathering curves for smoother zoom endpoints.
- Some locations with high RF activity showed reduced range performance with newer handsets even with antenna modifications.
- Battery life on G4-equipped handsets returned to levels comparable with older HU2 units after the upgrade.
Depends on
- Users experienced problems at specific locations like Paramount Studios and Universal, but causes remain unclear and may relate to local RF interference rather than the devices themselves.
- Reliability experiences with HU3 units vary widely between users, with some reporting no issues while others report persistent interference problems.
- The discussion involves unresolved disagreements about whether HU3 design or local RF environments caused reported problems.
- Limited information on whether G4 boards truly deliver the promised improved range and reliability across different shooting environments.
- No confirmation on pricing strategy or whether G4 adoption rates will eventually lead to cost reductions.
