23 cm Equipment
- VK5EME Transverter kit with 144 MHz IF
- Local Oscillator is "G8ACE OCXO"
- Power amplifier is homebrew XRF286 (Running at 300 W CW and 400 W PEP SSB - High Power permit
issued from ACMA)
- LNA is WD5AGO 32dB gain with NF= 0.29dB
- Feed.. RA3AQ Optimised septum feed made from 0.5mm thickness Copper sheet. It uses an SMA feed
probe for both Tx and Rx ports and an SMA Relay for LNA isolation. (At present the "choke flange" is not in
use)
- 144MHz IF radio is an IC746 or IC7700
