Modifying the Adret 5104 Frequency Synthesiser for 10MHz external reference.

The Adret 5104 is originally designed to be able to use a 5MHz external frequency standard.
With the availability of GPS conditioned 10MHz frequency standards such as the HP Z3801A it is more useful to be able to feed 10MHz into the Adret 5104 and lock to that rather than 5MHz.

This paper shows a method of modifying the Adret 5104 to accept a 10MHz reference rather than 5MHz.

EA4TX ARSWIN Now supported by MoonSked

MoonSked 1.5.1 now has a telnet driver for EA4TX's Antenna Rotator System ARSWIN. The driver can control a local copy of ARSWIN on a PC, or even a remote version running over the internet! It will automatically connect and send the password as required by ARSWIN. You can use the Macintosh version of the driver to control ARSWIN running on a PC (or indeed on a virtual PC on a Mac).
