This version (2.0.7)worked right away from me but after a few minutes the buffer fills up and the program crashes.

It depends on the use, the type of emission and the TX / RX period.
I used this heat sink I already had and that is enough for me. Hristiyan LZ5HP told me that up to 70° the PA is safe. Better not get to those temperatures.
Did you detect any reduction of Rx or Tx signal because of the PP box. This is a very good idea: there are many different sizes of box available.

I believe that every plastic box that has the microwave safe symbol is suitable for this purpose.
yes, problem end at 13:20 UTC on NB transponder
Here is my paired SG-LAB transverter & PA
Hristiyan LZ5HP answers everyone in English, is very courteous and helpful. If you delay in the answer it is probably because it is too busy. The address for any information is this:
Strange swipes on the NB transponder very visible when the transponder is not engaged by other stations besides the beacons. A pair of sweeps approximately every 9 seconds.
It's not believable because these statements are patently false or hyperbole.
As Secretary of AMSAT, I have not received and am not aware of any application for member societies ("affiliate") denied.
It is important to note that AMSAT as an organization is not opposed to Phase 4. This statement made above is entirely false. Why would an organization opposed to Phase 4 approve spending $100,000 for proof-of-concept testing on a launch that was never guaranteed? AMSAT invested because it believes in Phase 4 opportunities.
It is nothing new that AMSAT-affiliated organizations are often bound by Non Disclosure Agreements (NDA) and cannot identify launch partners. When a launch has been identified and agreements reached, it is not assured that the amateur payload will ever visit the launchpad. Anyone can make claims about "potential launches" but until there is a manifested payload sitting on a launch vehicle, it is all talk.
thanks for the answer Clayton.
I have no elements to reply to your post.
I can only observe that currently the AMSAT promotes/operates some mono-channel FM satellites and an old disused military satellite that allows you to do things that I did almost 30 years ago.
These are the facts. This pains me.
My gratitude to Amsat remains intact for all I received in the past. I cannot say that today Amsat promotes and stimulates my knowledge.
has anyone already received the Version V1.5 of the TR2300?
No answer from Hristiyan (LZ5HP) the last days, I hope everything is ok with him...

With SG-LAB you can feel comfortable. Requests are obviously many and waiting times are getting longer. But everything ends in the best way.
Remember the Falcon-9 that put into orbit es'hail-2?
Well, the second stage that is visible in the QO-100 DATV beacon will re-enter the atmosphere within a couple of weeks.

I hope my comment wasn't too raw.
It was a simple twitter-style service communication.
The version is a beta and so there is that it does not work with all devices.
Of course this does not detract from the great work of Jean-Pierre, whom we all thank for his constant and heavy commitment.
it doesn't work with Minitiouner-Express.
Test done? carrier OFF at 11:37 UTC
modulated carrier, different signal levels up to saturation.
The Muldifeed holder is from my view the wrong approach. It can only be one of the two mounted feeds in the focus of a satellite. Mutifeed holders are intended for the reception of 2 satellites, which also have to be positioned a few degrees apart.
in fact, just look at these two images to frame the problem. It definitely doesn't work.
