Re: Observations by W5LUA & AA5AM
I've seen the recommended level for the external reference to be 2 V P-P, which translates to +10 dBm into a 50 ohm load. My OCXO puts out +16 dBm, so I put a 6 dB attenuator on it. I have a 50 ohm resistor soldered across the input from the external reference on the 122 GHz board. I have had no problem locking it so far with that arrangement. I'll find out this weekend how well it works in the September weekend of the 10 GHz contest, when I actually have someone to work. 73, Zack W9SZ On Mon, Sep 14, 2020 at 11:55 AM Al Ward <w5lua@...> wrote:
