Since first putting a signal out on 500kHz a few months ago, I believe the ERP has increased by about 18dB. These steps were:
- Initial PA 500-700mW (0dB reference)
- PA output increased to 5W (+10dB)
- Additional grounds added (+2dB)
- Antenna spiral top hat added (+6dB)
After that, it will be farewell to 500kHz and welcome to the next challenge!
