F5OEO has finished his new DATV firmware version 0201 for the Pluto.
Be careful!
Its a alpha version, not all finished yet!
Its preferred only for small SR´s

no. DD0CW asked a few days ago and got this answer via eMail...

DL0SHF 10 GHz beacon this time is out of order. Failure of AZ gear.
Replacement as soon as possible,

Version 0.09b still running after WIN10 update last few days ..

you get also an alarm in the transceiver despite a transverter
No,
Thomas, Du musst dich irren.
I made measurements this moment to fix my statement.
There is absolutely no effect on the input of the transverter if the output is detuned on 2.4 GHz with bad SWR.
Even without a PA in between.

Bill,
I think there is absolutely no relationship between the SWR shown on the FT-817 and the SWR from the 2,4 GHz PA output.
Your problem seems to be between the FT-817 and the transverter input.
Cable connection flooded or something.
The dummy instead of the 2.4 GHz antenna must of course be suitable for the frequency and power.
But, as you write this, you have to look for the error between the FT-817 and the transverter anyway.
You can also connect a dummy instead of the transverter and watch the VSWR when it is wet.

the high SWR warning
What SWR warning?
Really measured SWR with what equpipment?
Try same procedure on a dummy load instead the antenna to find the real reason.

Great,
with or without original case cover?
Do you have a picture from the circulator bypass?

In a WIKI it is better structured probably.
I agree, and that is what matters!
In the forum you have to read everything together, there is a lot in different threads on the same topic.
If someone doesn't read along all the time, that doesn't help.
A wiki in the style of the BATC wiki, appropriately maintained, would be much more helpful for newcomers or experimenters.
In my opinion, the forum here primarily helps to get help and support for special cases.

Had same effects with somtime GPS loss ... , mostly after new start of the converter.
I changed the GPS Antenna, now without problem ...
Maybe a try?

then it makes no sense to reactivate my old AFREG-decoder
?? As far as I know did the AFREG decoder only generate the clock and data stream from the PSK signal what you have finaly to decode with software which uses the FEC algorhythmus.... (IPS running on ATARI 800, later ATARI 1040 and finaly PC)

The main problem is, that, as Peter wrote, some user did not educate them-self by reading trust-able and reliable sources first.
They work by try and error, did not respect the bandplans and regularity, partially they did not know about that, partially they don´t want to do that.
How do we reach this part of users?

Good linear signals are our visiting cards.
Yes, fully agree !

The LNB went up, so the beam went down. You have to adjust the dish as a whole a bit up again..
the angle of incidence is equal to the angle of reflection ....

Hello Bill,
the distance from the POTY to the dish reflector is not critical for 2,4 GHz. You have to adjust with the 10 GHz RX signal.
Your mechanical solution looks good, but in vertikal to satellite has changed.
So you have to adjust the elevation from your dish.
take a look here:

Datv Signal Processing creates a delay Up to 15 Seconds.
once upon a time ... with software that is no longer up to date.
Currently we are working with delay times of 2-3 seconds, DATV QSOs run nearly like in the NB ...
Please have a look ...

Yes,
to lengthen is the better idea, and you have more place/distance with the POTY reflector disk to the feed arm.
You have also a wider area to slide the POTY in direction to the dish reflector to find the best position for focus.
