By pure chance I found this UHF bandpass filter on the net and, given the price, I immediately bought it: € 8.99 including shipping costs (AmazonPrime) Nothing in particular, usually SAW filter in line with others of the same category in the same range of frequency. Definitely useful for those who need to drive an upconverter (70 / 13cm) for QO-100 with Adalm Pluto.

From the same family and from the same seller there are other filters for other frequencies but unfortunately they are not available for quick shipment. What do we buy with 9 euros?

Quote from DH2VA

pardon the question, but why do the two measurements differ so vastly? It is certainly fine for 2.4g but I don't understand the rest of the behaviour. Do you have pictures of the two setups?

Achim, my suspicion is that the adapter "MACOM N-male-SMA-female" not present in the circuit during the calibration phase has distorted the measurements.

Mike, DL1GNM will be able to clarify the matter better.

Hi Jerry, the duplex issue has been discussed in the past. Amsat-DL requires that the operator using the QO-100 satellite be able to listen to its emission and therefore to check that it is clean, that it does not exceed the beacon level, that it is on the same frequency as the correspondent. Basically these are the main reasons why duplex operations are required.

Quote from G4MQB

I think the PA output is about 17W but can't measure accurately, but is enough for me.

The PA SG-LAB supplies 22 Watts when powered at 28 Volt. If powered at 20 Volt it provides 12 Watts and at 12 Volt it gives you 5 Watts abundant. You can keep everything in the house and decide how to use it, with how much cable and with what output power.

The orange Input LED means that driving is low. If the output on the transmitter is fixed then you must adjust the TX Power trimmer on the transverter until the LED turns green.

The red output LED means Hight Output SWR

The meaning of the LED colors is specified in the SG-LAB manual.

Pay attention, then, to which version your PA SG-LAB belongs. There are three versions of PA SG-LAB.

These PAs are the same as regards the output but they are different as regards the input power. In any case, you will still need to insert an attenuator between the Transverter and the PA.

You should provide some details.

How much UHF power do you get into the transverter?

LED input: You have adjusted the TX POWER trimmer on the transverter to have the Green LED.

To have these conditions you must have a UHF carrier applied to the transverter.

You can either adjust the output power on the transmitter or adjust the TX POWER trimmer on the transverter until the LED turns green. Never exceed 5 watts of UHF driving.

Avoid having your IP assigned by DHCP.

DHCP could assign a different IP with each connection and you would never find your Adalm Pluto.

To see if everything works just type in your browser the IP assigned according to your configuration.

Once you have modified the "config.txt" file in Adalm Pluto, disconnect the power to your Modem / Router to make a "clean" restart of the various IPs.

When everything is connected with the new configuration, restart your Modem / Router.

Do a check as per attached photos.

Ich habe die beiden Schemata wieder zusammengefügt und vielleicht ist es verständlicher.

Unabhängig davon, ob Sie die VOX RF oder die PTT des Geräts verwenden, ist dies das Schema zwischen dem Transverter und der PA.

The two IPs are the same and I think that's the problem.

Here you should put a different IP.

So in the program, for example SDR-Console, you will have to create two different configurations.

One when you connect Adalm Pluto via USB ( IP 192.168.2.2 ) and another configuration with the second IP (for example IP 192.168.1.180) when you connect via LAN.

Once the IP is changed in the USB_ETHERNET section of the config file

just put in the browser the IP address you have configured (for example 192.168.1.180) and you will see the welcome page of Adalm Pluto.

Thomas, I was fixing the links that the forum didn't show separately.

Mike, I think many of the problems depend on the power of the devices. Many computers supply 4.8 Volts on the USB port which are not exactly the same as 5 Volts.

hi Robert,

I don't know if this can help you.

happy holidays...

Hello Peter,

I'm glad to see old friends in space ...

Perhaps it is useful to spend a few words on these two brothers in orbit.

At the time there was no Internet, the Packet was not yet born and the only way to have fresh Keplerian elements, newsletters, first-hand news was to receive these two satellites that had no transponder on board but only a space-earth link .

At the time, we adapted to anything. No SoundModem to use. Only fantasy and welder. In this article written for the Amsat Italia bulletin I described how to use a telephone modem to receive the UoSat-1 & UoSat-2 satellites. It is written in Italian but the patterns are universal.
