Hi Chris,

as you can see in the SG-Lab data sheet, the vox already works with 1mW input, so it only needs a low level to switch PTT. Your CN0417 module with approx. 20dB ampli generates a maximum of 50mW from the approx. 2mW of Pluto, which has been attenuated by 6dB. This is perfectly sufficient to fully drive the PA. Depending on the transmitting antenna used, the level on the QO-100 is much too high and the Leila is activated. Here you should set the maximum levels for Gain, Drive, etc. accordingly in the settings "Transmit - Options - Audio-in - Gains".

I hope this is of some help, if Mr. Google translated everything correctly

Which type of SG Lab PA you are using?

Hi Rüdiger,

that works only with the MiniTiouner version with 2 USB ports. I have planned this in my replica of the MiniTiouner by Jean-Pierre F6DZP, but unfortunately the announced software-update from F6DZP is still not available.

Hi,

has someone tested the connections TX2 and RX2 in Rev D and if so, how and with what software?

AD writes:

The 2nd Rx / Tx channel internal to the rev D is not test during production test. If it works - bonus! If it doesn't work; Pluto is only advertised as a 1 Rx, 1 Tx radio, and that is guaranteed / production tested on each unit - and that is what you received.

here my config.txt with a fix LAN-IP 192.168.0.25 and Router IP 192.168.0.1 (FritzBox)

I hope this could help:

[NETWORK]

hostname = pluto

ipaddr = 192.168.0.25

ipaddr_host = 192.168.0.1

netmask = 255.255.255.0

[WLAN]

ssid_wlan =

pwd_wlan =

ipaddr_wlan =

[USB_ETHERNET]

ipaddr_eth = 192.168.0.12

netmask_eth = 255.255.255.0

[SYSTEM]

xo_correction =

udc_handle_suspend = 0

[ACTIONS]

diagnostic_report = 0

dfu = 0

reset = 0

calibrate = 0

If you are interested, the extensive changes can be read in the file releasenote.txt (see attachment).

One of the improvements that I am personally enthusiastic about is the option of sending the data directly from the spectrum shown to my Minitiouner (see picture)

Hi to all,

F5OEO has finished his new DATV firmware version 0201 for the Pluto.

Many thanks to Evariste F5OEO and all contributors.

Here is the link to download:

http://firmware.hackhamradio.com/alpha/

That's my MiniTiouner version without SMD's on the board, hi.
It's running with Scan&Tioune.

For more infos see my pages on qrz.com

In the meantime i have found out that the stream settings are irrelevant when using UDP. To start the data stream you have to use the "Start Recording" function instead of "Start Streaming", which may sound a bit illogical.

If you want to use the ADALM-PLUTO DATV controller to set the parameters of the Pluto, you have to send the OBS data to the Pluto via UDP stream. Above you can see what has to be entered in OBD under "Output" "Recording". But what do you have to enter under "Stream" in the line "Server" and "Stream Key"?

The update via web does nothing more than copy the file pluto.frm into the Pluto and send the Pluto a reset command, whereby the Pluto installs the firmware independently. This only automates the manual handling of the update. It couldn't be easier and a newcomer should be able to do that too, hi

DD0CW, The upload function via web is only part of the firmware of Everiste and not of the original firmware of Analog Devices

I have just made my Pluto happy with the firmware update via web page and it has now thanked me with a flawless and extended function.

Thousand thanks to the hardworking developers of this excellent software

DM5RM Hi Roland,

yes, very mysterious things are already happening inside Pluto. It would be interesting to know whether a commercial SA produces the same results and which spurious waves are actually generated by Pluto. In my 2.4GHZ-PA, a multi-circuit filter ensures the suppression of secondary waves, but only if they are outside the passband

DM5RM Hi Roland,

thanks for the hint. What I am missing is a manual for the software with an explanation of the individual operating functions or a help function. Otherwise the software is an excellent addition to the other pluto programs.

What irritated me: as soon as you set the Span to 61MHz, you can see another signal at 2407.8 MHz only about 10dB weaker than the one at 2400MHz. With a Span of 60MHz this signal is not activ. Depending on the span and generator frequency, signals appear below or above the generator frequency with different levels. If pluto generat this continuously, it would be fatal, as this signals could appear in the DATV band.

DM5RM

I did and I got the same results

Hi George,

that's exactly what I did. I wanted to use the analyzer to examine Pluto's output signal. Apparently the internal crosstalk is so high that even without an external bridge the Tx signal can be seen along with plenty of spurious waves. My Pluto is housed in an aluminum box. The crosstalk seems to be already happening on the Pluto board, which does not speak for good RF quality.

This hardcopy was created with SA and Generator on and without any connection between the Rx and Tx sockets.

How can that be?

Is it possible to connect the two connections internally via software?

I've tested this on various frequencies from 400MHz to 2400MHz.

TX Pwr has no influence on the signal level.

Hi Frank, of course you are right. That also occurred to me later. I took the measurements in the DATV reception position. The signals from the NB are therefore several dB weaker.

Nice tool, works excellent.
Many thanks for your great work, Alberto.

P.S.

the hardcopy shows the input signals of my pluto (range: 739-750 MHz)

The DATV signals are much stronger than some SSB signals.
Now a new hardcopy with TSA calibrated (range: 739-750 MHz) .
