Transistor Bias Voltage (PTT) Switching options Selectable by Jumper:
1. PTT is switched ON by connecting PTT pin to the ground.
2. PTT is switched ON by applying +3....+12V to PTT pin
3. PTT is switched ON simultaneously with Power Supply Voltage.
Directional Coupler Voltages:
1. FWD Voltage Input 0.5V typ. @ 0.5W input power
2. FWD Voltage Output 3.5V typ. @ 20W Output power
3. REF Voltage Output - reflected wave , can be used to calculate estimated output SWR
Hi,
according to Noel, G8GTZ, 5 sets of the BATC minitiouner will become available next monday, Dec 4th
Hi,
quite easy, this LNB has NO internal switch and delivers H low, H high, V low and V high, each on a single F connector.
So one connector for NB and one for WB.
For distribution in a house you need an external multiswitch.
I have a 2.6" Digole display for my minitouner and search for a bezel. Do anybody know if there is one available or if there some stl files for 3d printing ??

Hi Elmar,
bezel for which kind of housing?

here the translation of the russian part:
Why build? Today I am conducting some tests with replacing an external LNB source or internally replacing an XTAL and giving an external signal. In any case, I use 6 types or different LNB modes, such as STRONG R739, Octagon OSLO 1609 and others. In the end, another big question is why the same RDA3566 processor used in different (all) models does not use load capacitors and does not work with an external source? it is after each experiment - XTAL is still inside or deleted, etc.
+ - 1.5 MHz as a guess----
Does flashing indicates that in some point in time a carrier is recogniszed but not locked?
Have you also tried to adjust the offset frequency a litte bit to higher or lower values?
BTW: PIDs are different !!
Hi,
have you tried to tick on the "wide scan" button?
Seems that MT is not locking.
Best solution from my point of view:
Minitiouner Pro
Here is the measurement of the filter I have. It looks simmilar to the picture from the advertisement. For WB some adjustments are needed:
Will you work out how to move frequency upwards for WB?
And if the sample fulfills our requirements than does did not mean that the mass production has the same quality ....unfortunately my experience.
You have to be onsite to verify/control the production process
Looks like the dish sold by G3RUH:

Hi,
currently, 11.02.2019 @ 13:20 UTC, on the wideband transponder the promo video of Es'hail is shown, H.264 DVB-S2. Low MER....hard to decode
10495000 6500ks 5/6 QPSK
uplink from Qatar / A71A
How big would be the effort to move the center frequency of the passband a little bit to higher frequencies?
I do not have access to an analyser..
Out of curiosity:
Would this module be used in A-mode or AB-mode for best linearity?
Hi,
for the DATV transmission a DVB-S and DVB-S2 receiver is necessary. As also DATV transmissions with reduced bandwith are to be expected, a good solution could be using Mini Tioune. Have a look here:
https://wiki.batc.org.uk/MiniTioune
I guess that worldwide analog transmissions via Sat are not longer available.
If you wish to use a commercial receiver make sure that it allows symbol rates lower than 1 Mbit.
The RED (radio equipment directive) applies.....CE is only one part of the story.
But customs officers are mostly not so deeply involved in european laws.
Hallo Achim,
was muss man beachten, wenn man den 2.4GHz 20W Booster bestellt?
Welche Zollrechtlichen Dinge sind zu beachten?
Muss aus der Rechnung ersichtlich sein, dass es sich um Amateurfunk Ausrüstunghandelt?

Moin,
meistens schreiben die chinesischen Versender nur unspezifische Angaben auf den Versandkarton. Je nach Versandweg kann das Päckchen problemlos durch den Zoll gehen oder Du bekommst einen Brief vom Zollamt, dass Du dort die Sendung abholen und verzollen bzw. die Einfuhrumsatzsteuer zu entrichten musst. Die Sendung wird in deinen Beisein zollamtlich geöffnet und begutachtet. An dieser Stelle ist die Vorlage der Amateurfunkgenehmigung und eine einfache technische Erklärung, was mit diesem elektronischen Bauteil passieren soll, hilfreich. Die Beamten beim Zoll sind keine Techniker, aber häufig technisch interessiert. Die meisten Beamten schauen nur nach dem CE-Kennzeichen und einer deutschsprachigen Anleitung (beides Pflicht bei "normalen" Wirtschaftsgütern). Hier hilft der Hinweis auf die Rechte und Pflichten des Funkamateurs bzgl. Selbstbau.
Hoffe, ein wenig geholfen zu haben.
