[hpsdr] PennyWhistle - Call for Comments

[Graham / KE9H]

All:

Before I do a layout of the (hopefully) final
version of PennyWhistle, I would like to call
for comments.

If this is something you would be interested in,
please review...

It has been updated with an "off the shelf" output
transformer from Communications Concepts, as well
as the power output versus frequency plots have
been added.

Questions:

Do you prefer BNC versus the SMA connectors shown?

Considering the differences in power output at
6 Meters versus HF, should a relay be added that
would switch the output peaking between HF and
6 Meters, or is the performance with a fixed
capacitor at one setting or the other adequate
for your purposes?   (that is, keep it simple)

Is a bare board kit preferable if it saves multiple
months for availability?  Are you comfortable
building a kit with about two dozen SMT parts?

I have a suggestion from Phil H to add a feedback
winding to (optionally) reduce gain and increase linearity
when used as a driver for linears.

I have a suggestion from Lyle J. to try the RD15HVF1
in place of the RD16HFF1 transistors to increase
performance at 6 Meters.
