I need a matched transmitter-receiver pair built around a 200 kHz carrier that can cover at least 40 m in open air and recognise simple OOK (On-Off Keying) pulses reliably. The intended application is… (Budget: ₹40000 – ₹250000 INR, Jobs: Antenna Design, Electrical Engineering, Electronics, Embedded Systems, Microcontroller, PCB Layout, Radio Frequency, Signal Processing)

I’m flying a freestyle FPV build that carries an EP2 Nano receiver, yet I still can’t get it to talk to my Radiomaster Pocket running EdgeTX. I’ve tried the usual bind procedures but I’m clearly missing… (Budget: ₹600 – ₹1609 INR, Jobs: Drones, Electronics, Microcontroller, Radio Frequency, Technical Support)

I need a custom single/multiple-turn loop antenna designed and working physical prototype fabricated. The target band is low frequency (LF), and the antenna will be used exclusively for near-field coupling applications… (Budget: $750 – $1500 USD, Jobs: Antenna Design, Antenna Measurements, Antenna Services, Electrical Engineering, Electronics, Prototyping, Radio Frequency, Radio Frequency Engineering, RFID (Radio-frequency identification), Wireless Radio Frequency Engineering)

US-BASED or MEXICO-BASED CONSULTANT ONLY We need a US-based consultant to test antenna cables in a Vector Network Analyzer. Each unit must be swept across its operational band and documented: See attached reports as examples of exactly what we need… (Budget: $25 – $50 USD, Jobs: Antenna Design, Antenna Measurements, Radio Frequency, Radio Frequency Engineering)
