I notice that you are using Chris Lee's driver and DVB app more and more and of course Deeptho's. For this reason, I would like to know what are the significant differences in terms of performance between the two Linux applications?
There are restrictions in the tuners that are able to be be used with updateDVB, either in a desktop (or laptop) PC or a micro computer such as the Raspberry Pi.
These tuners which I have work fine for me for DVB-S/S2 - TBS 6925 ( USB TBS 5925 in the RPi, but not the TBS 5927) and TBS 6903/6983.
I have tried my TBS 6903X, but although the card is recognised in updateDVB (shows in the adapter settings), it doesn't do a spectrum scan or blindscan.
For DVB-T/T2, TBS6220 and various DVB-T/T2 usb sticks work fine.
I have a TBS 6522 which can recognise DVB-S2X channels, but it's been removed from the PC, so I can't try it with updateDVB. Maybe later.
As Chris Lee doesn't seem to be working on the app at present, we may have to wait for any further drivers for other cards to be available. It's being maintained by others in the US Rick's Wildfeed site, so maybe other tuner cards that I don't have can be used.
Performance-wise, it's excellent with low SR TP's, for instance it readily finds Radio Immac (SR128) on 16E 21564H on a blindscan or clicking on a section of the spectrum scan (as you do with Crazyscan in Windows). Only drawback is, you can't blindscan the spectrum scan graph to find working TP's as you do with Crazyscan.
As I said, the TBS 6903X doesn't work in updateDVB, so blindscan comparisons with neumodvb using the card aren't really relevant.
User-defined LOF frequencies can be set using the Custom button (similar to EBSpro in Windows), something not yet available in neumodvb, allowing for instance KA LOFs to be entered.
