Someone asked about the power of the Epson oscillators. The one I use
for Hifer RT measured +12.34 dBm into 50 ohms including the low pass
filter. I use an external attenuator to set the power into the antenna
properly. My implementation does not include the pot used in the
original design.
According to my notes, I made this measurement through a 20 dB
attenuator into a 3586C frequency selective meter. I recall I had a
similar reading with another 3586C at the transmitter site. The filter,
measured separately, was down a little less than a dB at the transmit
frequency and was down over 39 db at 26 MHz. I did not make
measurements with varying temperature or voltage.
