PORTABLE / CONTESTING / FIELD EXPERIMENTS
Portable and rover operation is an RF-engineering problem that moves. A vehicle layout must balance antenna clearance and rotation, equipment power, feed-line loss, quick band changes and safe handling.
VHF/UHF rover architecture
The current design discussion centers on a pickup-truck rover for East Texas, southern Arkansas and northwest Louisiana. Radio racks separate 50–432 MHz equipment from 902/1296 MHz transverters and IF interfaces. Planned antenna choices include roof-mounted loops and short rotatable Yagis, subject to safe mechanical clearance.
Why the IF design matters
- A low-power, frequency-stable IF radio is important when driving microwave transverters.
- Independent sequenced PTT and audio routing reduces wrong-band and wrong-antenna mistakes.
- An RF inhibit or STOP control should end transmission predictably.
- Coaxial relays, surge protection and antenna grounding must be appropriate for mobile operation.
Operating priorities
Choose stops based on horizon, terrain, safe access and predictable activity rather than maximizing height alone. Coordinate rover schedules with other participants. Log local time, UTC, grid, band, mode and successful paths so future routes benefit from actual data.
What still needs testing
Final amplifier power, mounting hardware, structural loading and vehicle routing remain project decisions. Nothing on this page constitutes a road-safe installation certification.
