Everything which is blocked can not be transmitted.

So if you put it after the PA it will eliminate all rf (ok, mostly) outside the bandpass.

If you put it before the PA all mixing products which can occur in the amplifier will go to the antenna.

So I would recommend the installation after the PA.

Hope that makes sense.

2 watts? What giant dish are you using

Kurt

According to this link https://wiki.batc.org.uk/QO100_DATV_Users, Mike uses a 2,4 m dish and 32 watts...

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

DD0KP Sorry new to this, how do the LNB's work if they only require 12Volts to be either H or V ?

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.

DK5FA: Hast eine Mail.

Moin,

ich bin auch im Besitze dieses Filters (samt PA), habe allerdings nicht die nötigen meßtechnischen Mittel, um die Durchlasskurve ein wenig nach oben zu verschieben.

Wäre hier jemand bereit, mir hier zu helfen,?

+ - 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..
