Re: VLF: Carrier on 8270.0025

[Riccardo Zoli <riccardozoli80@gmail.com>]

Hi VLF,


I'm running another carrier test on 8270.01953125 with about 600 mA
and 14 µW ERP.
To reach this current, I need about 290W on the PA output, currently
supplied with 62V and 5.5A.
There is a lot of power dissipated by the coil: a cooling fan is
absolutely necessary.


All the best
