I already spotted that the Sony CXD2820 is a DVB-T tuner. The problem is the driver. For the this Fortis model two different DVB-T tuners were sold. The early model does not support DVB-T2. It has a Sony CXD2820 tuer and a Samsung 5SH1432 demodulator. Both the driver and the datasheet for the latter are confidential and for that reason are not part of the image I can offer. As far as I know a driver can be found in Bpanthers' Neutrino images, but this will not solve your problem, as only the later DVB-T tuner supports DVB-T2. At present I do not know which chips it is based on.

In the past I have started work on a driver for the older model, but my tuner module broke down while working on the driver. These tuner modules are hard to find, as the majority of the receivers were sold and used with 2x DVB-S(2) as tuners and this receiver model is slowly coming of age and re-/disgarded as obsolete, although it is my favourite Fortis model.

Hi Audieniek,

thank you for your fast reply. I just tried the original Octagon 1028P software from 2017 and found that it allows me to tune in to DVB-T2 channels! So I seems I have the "newer" variant of the Sony CXD2820 tuner - sometimes this is possibly referred to by CXD2820R (https://www.linuxtv.org/wiki/index.php/Sony_CXD2820). The latter link also refers to open source Linux drivers but I'm not sure it helps. Do you have a link to Bpanther's Neutrino images?

(The situation is that I am located in Denmark where more and more channels are moved from the DVB-T to the DVB-T2 standard, so this is why I'm interested in receiving the DVB-T2 channels. In the worst case, I have to move back to the original Octagon software or buy a new receiver.)

The other issue I mentioned is that with your build of the atevio7500 image, the DVB-S tuner does not allow me to tune in to vertically polarized channels on Astra 19E - which works with the latest HDMU image, though. I know I am demanding a lot, but can you reproduce this issue with your DVB-S tuners on the Octagon/Fortis?

Bpanthers Neutrino images are here. You to register to be able to download them.

Same here. The Dutch provider KPN has been so kind to abolish DVB-T too soon, rendering millions of usable receivers worthless,

I know I am demanding a lot, but can you reproduce this issue with your DVB-S tuners on the Octagon/Fortis?

On my Rebox RE-8500's (I have several), all DVB-S(2) channels tune fine, so I cannot repoduce the problem.

hello mrspeccy & Audioniek

Thank you, but as said above, The Sony CDX2820(R) is not the problem, the elusive Samsung 5SH1432 is...

I will try and check if my RE-8500's can receive DVB-T2 with the newer tuner.
