Subject: VLF: 8970 Hz Op-4H
This morning I have reconnected the VLF amplifier
and coil to the antenna, and started to transmit on 8970.000 Hz (Rb
controlled). Sent a more or less uninterrupted carrier between 12:30
and 13:30, and have started an Opera-4H sequence at 13:41.
With 0.33 amps up to 9 m my estimated ERP would be
around 20 uW. The carrier seems to be well visible on the OK2BVG
grabber (up to 10 dB in "600"). I'm now trying to reach opds-4H at
DK7FC but the SNR (10 dB for the carrier in "6000") may be just a bit
marginal.
Best 73,
Markus (DF6NM)
