If I want to bring the forward and reflected voltage signals out of the case of my on order AMP2400v3 do I need to use feed through capacitors, and if so, what value might anyone suggest please? For cooling would a big computer CPU cooler with a small 12V fan be up to the job? The cooler heatsink's footprint is similar to that of the amp's case. Thanks.
look for more info in this thread:

It works fine for me. and use the values for a simple SWR meter in the case where the transverter is built in.. -
I am not the one who wants to be in the spotlight
but for this time I want to make an exception
Roland, thank you for the nice program
See also the E-mail I sent to you

DD4YR ,,
My own also has 2 USB ports Robert, but as far as I can find in various reviews and descriptions also the micro USB don't provide data transfer either
-
There is a USB connector on the bottom for charging only, it's not designed as a data port.
So in this case you will have to enter the Smith Chart data by hand

Yes, but as far as I know it is not supporting Smith-Charts which is IMHO a big drawback
Kind regards
Matthias
DD1US , You are absolutely right Matthias, but he is very handy as an aid to make a feeder
As Martin also wrote, "Habe auch gute Erfahrungen mit diesem VNA gemacht ..." I also have good experiences with this VNA
A few pictures of the VNA while testing my feeder

DD0KP Hi Heiner
I read the article about this possibility but thank you for mentioning it.
The power supply for feeding the LNB is no problem.
I made a Bais-T with the possibility to switch between 12V and 18V and it works great.
The original question was whether it would be wise to supply the LNB with voltage 24/7.
Given the answer I leave it as it is and as long as the LNB continues to work.
Attached some photos of the Bais-T i have made

Hi Lucio
The reason for this question was that I still have to make a few minor modifications in the transverter housing.
And whether I would also supply the LNB with voltage from the transverter power supply
which is not always on.
So I think it is indeed wise to supply the LNB with power separately, and leave it 24/7 on
Thanks info
Ciao, Jan -
Hi all.
A lot is being written about modifying various LNBs
But I have, maybe a stupid beginner question,
about the practical use of the LNB.
Since 2 months I have had a dual band patch feed
,with a TXCO modified Otagon LNB,
and I wonder what is wisdom
constantly provide the LNB with voltage
or is not that special necessary
I know that some commercial sat receivers keep the
voltage on the LNB in standby mode and others don't?
Does anyone have a tip in this ??
Tnx Jan

PA3FBX , Benno
I have sent you an email to the email address which is known on QRZ.com, did you receive it / read it?
Received no response so far, Is this email address still correct?
If not, send a correct address to my email address which you can find at QRZ.com
on7kec , Tnx Luc, this version works much better

I made a test transmitter from an old LNB according to this article
http://www.kh-gps.de/hb100.htm
Know it is not a supper solution but you can test your LNBs with it
Good luck

When did you order the PA? ... I have already emailed SG-LAB several times but I don't get an answer ... And the website still says "coming soon"
