**Answering your question; yes, GND can be too good, especially if you cannot
match the optimal termination.

Due to this years extended summer season temperatures, many of the

Additional question;
with respect to the BOG/Beverage backlobe upwards angle, does the
test-generator antenna need to be lifted from local groundlevel by say 2-
10m?
Or can this test be done just as reliable on groundlevel?

Another question might be; how close by is this BC station or any other AM
BCB stations?
Please consider a HP BC stopfilter

more experience on this subject will have a better
answer here.
In general, my experience is a beverage antenna will work rather quickly and
perform well.
There is just no bad-adjustment possible.

Hi Mark,
When receiving

abt 65dB
You do the math when you have 9+40 signals on a large antenna like a
fullsize TX deltaloop on 40 & 80m

Can they add /RHR or such please?
So I can choose if I want to make this kind of QSO.
BTW, I require a remote solution for climbing Everest or participate in Car

That is currently not possible from where I am sitting and I demand the

It is difficult in noisy areas; you will have to find a way to work around

Audio latency 'differences' can be shown in the shack already;
my TT ORION vs a K2 vs a Perseus SDR show small but significant time
differences.
Especially the SDR is 'behind'.

If you can manage building such a remote station, a TX antenna will be possible
