[hpsdr] Phoenix

[Phil Harman]

Hi Lyle,

Graham has the Alpha Tx PCB for Alex now, this provides all the LPF's, 
antenna switching, directional coupler etc for either Penny or a future 
100w PA.

He has also designed the companion board for receive that has 
switchable attenuators, high and low pass filters plus a low noise 6m 
preamp. This will be next out of the gates.

Mercury already has a pre-amp so that is ready to go.  This weekend I 
married an LT2208 evaluation board to an Ozy board to make a prototype 
Mercury board. With this on the Atlas bus together with Penelope and a 
second Ozy board we have a complete (QRP) DUC/DDC transceiver.

We are short of a 100w PA that will take 200mW or so and give 100w out 
from 160m to 6m - not a difficult project with current power FETs it 
would seem.  Alternatively, Dishtronix (http://www.dishtronix.com/) are 
going ahead with their 600w PA which Penny will interface directly with.
