Meanwhile I've modified several LNBs for external LO feed. Therefore I use the NB output to supply the LNB with 25MHz, DC and of course the downlink.

Using my 27 MHz HD-Line HD-BP2 gives me still a DATV Beacon MER of 10.7dB.

The following LNB are not as good as the HD-BP2, I loose about 1dB (!) sensitivity:

OCTAGON Twin Green HQ, Model: OTLG GreenHQ, no Serial No. T1015, SPT SP4202HN, 25 MHz X-Tal,

like OE2ROL did: https://www.oe2rol.com/octagon-lnb-umbau-fuer-qo-100.html

OPTICUM TWIN LTP-04H

Same as AMSAT shows here: OPTICUM LTP 04H Twin LNB

In all cases the Leo Bodnar GPSDO was used. I tried to optimise the LO Power, but still no improvement compared to my old LNB.

To Try: Diavolo Twin. Transformer missing. See here: https://elektronik-muenster.de…lnb-f%C3%BCr-externen-lo/

I want to change, because my own GPSDO will have 10 MHz + 25 MHz.

Any suggestions? Please let me know. Thank you.

Good luck & 73.

Jean-Pierre, it worked. Great. Now for an unknown reason I cannot reason VLC cannot read the stream udp://230.111.111.112:10001. OBS can. Sometimes. DB0HEX (rtsp://90.187.0.205:2555/axis-media/media.amp) works. But not in OBS. Sometimes. It's confusing.

I've Win10 20H2. After this update, some things are different as they were before.

A computer connected to the internet has to be up to date. But I hate the trouble you often have after updates.

OK. I found the vlc problem. After reinstalling 32&64bit VLC all my network "presets" were erased. For an unknown reason vlc needs an @ in the command line: udp://@230.111.111.112:10001. This is different to OBS and confused me.

Thank you Jean-Pierre. For an unknown reason, 64bit installed in /Program Files (X86)/VideoLan/ ?!? I'll try it again and will look for the correct directories. 73 Mike

Yes, interesting indeed. Please let us know.

A 2.4 GHz low loss lowpass could be something mechanical (big). May be Achim DH2VA could have an idea. Or someone else.

An 2.4 GHz circulator will have insertion loss. I think out of band it has much more attenuation which is helpful here.

73 Mike

How can I use VLC 32bit in parallel with 64bit? I've OBS-64bit and this requires 64bit VLC (because of VLC input streams) . If I install 64bit even in a different path, 32bit is somehow deactivated and minitioune does not work.

If I install VLC 32bit, OBS doesn't have VLC as input source anymore.

I could copy the required 32bit DLLs into the minitiouner path if I know which ones (and if it works).

Any ideas? Without installing a 32bit OBS?

Regards, Mike

Gerhard,

Can you check your spectrum up to 12-13 GHz somehow? May be there's something spurious you wouldn't expect.

Or harmonics (did you measure?):

2405MHz x 4 = 9620MHz; will probably not fit into the waveguide. Not sure.

2405MHz x 5 = 12025MHz; will pass the waveguide. Could overdrive the LNB stages.

The noise increase is not independent from output level, when does it start (level)?

How long is the waveguide of your POTY? Did you shorten it?

Rolf, this works with Version 2312 and patch UII 2.4 too.

Robert, 0.9b works surprisingly. 1.0b didn't.

But I found a solution:

Delete folder =>

C:\Users\-USERNAME-\AppData\Local\QO_100_WB_Live_Tune

then it works again. After closing live tune, new parameters are stored again correctly.

-USERNAME- is your user name.

I've still no idea what happened. But it is fixed for now. 73 Mike

After updating my win-10 today, QO-100 WB Live Tune.exe does not work anymore. It even does not show up. With mouse over on the icon => see picture attached.

It may be something that's .net related.

Any ideas?

73 Mike

Christian & Evariste: thanks for your support. FW works so far.

I would like to have a feature that will prevent the pluto overdriving (by accident) the following amplifiers.

The "Power (0.1 dB steps) " regulator should get a user defined "max. limit". So you can't go over it by accident.

What do you think?

73 Mike

I'm using CH3+8 (2.4GHz) and 5GHz as well. My Antenna is 10m away from my house. No problems so far using the NB transponder (2W+POTY+1.2m offset dish).

WB and more power could be different...

Quote from DD0CW

But I have one more, and like I think, vy important wish:

Sometimes it happens that you start the controller and you are already "ON AIR".

Could you change the PLUTO.PHP so that it starts always with the "STAND BY" status ?

This would be very usefull to prevent unintended TXing and collision on the transponder.

It would be a good idea to the choice when possible.

If the state of PTT switch ON or OFF could be stored with

Save for next reboot

Warning : In order to write permanently, you need first to apply setting then Save to flash.

could be a solution? Just as an idea. Pluto comes up with the saved state.

Anyway, it's progressing and it's awesome.

Hello to all,

The next version including the spectrum masking but also the possibility to drive a minitiouner will be released soon... Here a demo in video

Don't forget that it is a short circuit development... I mean there can always be bugs and omissions.

Don't hesitate to share your comments and wishes... A blog page available for this purpose .

This integrates the "QO-100 WB Multi Quick Tune" tool!

Great!

I use for security reasons a script blocker. If eshail.batc.org.uk is blocked, there is no spectrum displayed. This may be another possibility.

Update done via browser. Works. Thank you.

Quote from DB2OS

You're right, I know a few other people on our planet Earth, who would be better sent to Mars first, or better just pass Mars.

I'll be back!

Should be shot behind the Transpluto! Mars isn't far enough!

Hey Peter,

Don't fly away !

Works now. Thank you. A small difference made a big impact.

Hello Alberto,

tried this as well without success.

Is a port no. missing?
