Lyle-

Phoenix progress has kind of stalled on my end due to unanticipated
drains on my time both at work and in the evenings.

I have been monitoring the list on a daily basis to keep up to speed on
other HPSDR activity (with particular interest in the QSD discussion
related to the Odyssey project).

In addition to a general shortage of time I am also temporarily devoid
of debug/troubleshooting facilities to bring a new design to life.
Hopefully that will resolve itself in the not too distant future.

After quite a bit of contemplation I think that an invitation for
assistance from others who have more immediate time and facilities is in
order so as to not unduly delay the realization of Phoenix now that
Janus and Ozy are on the verge of becoming releasable designs. I've been
delaying the plea for extra involvement in the hope I'd have a large
block of time open up, but for the foreseeable future this is looking
kind of doubtful.

If anyone feels like becoming involved in the development of the Phoenix
board (integrated HF RX and TX) in either actual board design and or
bringup/testing/characterization I'd be more than pleased to have them
become associated with the project. I really dislike having the project
unduly delayed due to my current lack of time and facilities.

Best Regards & 73,
