> Hi all:
> Here is a EME event you cant miss.
> Dust off your CW key, its time for Satellite, QRP EME.
>
> The 1,000 foot dish has 60 dBi on 432 mc and 400 watts.
> That comes out to be approximately 243,902,443 Million Watts ERP.

> The Arecibo Observatory Amateur Radio Club will be putting the

> The scheduled times of operation are:

> Tx power: 400 W

> System noise temp: 330 K (when pointed at moon)

> KP4AO can be heard with a small hand-held yagi pointed at the moon and a

> We will listen for calls at frequencies 5-15 kHz higher than our own,

Every time I think or mention Mary Jo, somehow the 57 VW Beetle comes to
mind. So, it is with the IRF510 and homebrew QRP rigs. They indeed are
found frequ...
