As a follow-up to my original post, here are a few additional comments.
Don, you mention that you designed the mini-flag for a deep null off the
back at low elevation angles
the other way around.
The best protection is to cover everything: the sequencer you have installed
will help by preventing hot-switching or switching transients. Lightning
protection protects against much more than just direct hits. You should also
have something that prevents overdriving your amp.

The C6AGU antenna feed-point impedance was measured at 9 - 130j Ohms. (I use
a remote tuner.) If you measure a much higher resistive component, it could
indicated that you need to improve the GND system.

SDR-s can work for in-band RX, but you must have a very "clean" RX (and TX)
paths and plenty of antenna separation. Also, lots of shielding and
grounding.

"Richard (Rick) Karlquist" w
on topband. Keep
up the good work.
One final note. One of my goals on topband each season is to connect with
enough countries on CW to achieve DXCC. This was a modest year with 130 or so
in my log.
And CQing helps.

put an inverted V higher than 100', you may get a better antenna,
especially if your QTH is over poor soil and you have only a few radials.
Really, there is only one way to tell: Try it.
Ultimately, having both will give you the best performance.
I know this is not very helpful, but ...

I was on a around that time and I only heard a few NA stations calling CQ.
Unlike earlier this week, not one EU signal in FL (on a noisy TX antenna).

You were an outstanding signal as well Don, up to 599 at times

good though: salt-water.) Still...
Good CONDX on TB! Take advantage of them while they last.

Steve,
Sorry, I did not directly answer you question. Look at the specs of the
IF3602. (But also look at the price!)

Steve,
The J310 is normally a pretty low noise device.
Perhaps you should look at filtering the power supply and any control and
feed cables.

interference (man-made noise included), but since they have failed to do
that, they should allow more power to restore the original signal to noise
ratio? (Which some already do, anyway.)

Chris,
Good choice.
Perhaps one note of caution. With a BJT input like this the input current
noise may be more dominant, unless the input impedance is kept low.
Would be great to see the final design.
