Hi.
I'm borrowing my grand daughters laptop that has Windows 10 and will try to see if SharpTV will pull in 405 lines on SECAM. If so I'm going to do some pleading with SdrPlay to see if they can come up with something for Linux and tell them about the Heritage project, I'll also contact Steve and Martin.
Cheers.

Hi.
I got an email from a chap in Russia who is either the writer of the program or someone else involved with it. It was rather hard to decipher but the gist of the email is that 405 lines shouldn't be a problem and none of the obsolete standards would be either. He said that a Linux version is on the cards too along with support for other SDR units. No time scale was stated or any other details. Very promising and I wonder if 180 & 240 25p is a possibility? I just wonder how that would work as an overlay on the monitor screen. Thinking out loud here..... I wonder how a raw video signal could be obtained, Peter Scott's way with modelines perhaps?
Cheers.

Hi.
I borrowed my granddaughters Asus laptop today only to find out it was unused for two years and wouldn't even post. I've charged it and although it seems to power up it does nothing. It will power down holding the power button in for a few seconds. Will need to see if I can get a copy of Windows and try it in my PC.
Cheers.

Hi.
Well my Windows 7 experience has not been particularly great and it has brought back to me the reason I migrated to Linux many years ago. I decided to go down the route of installing windows 7 alongside Mint. Initially I copy the "home" folder of mint to a spare HDD, this means you can over write the home folder on a new installation of mint with all your downloads, documents, desktop, moxilla with all the sites and passwords retained and the same with Thunderbird mail, as easy as that and something you cant to my knowledge do with windows. I installed Win 7 Ultimate which took some hours after the updates etc only to be hit with no keyboard or mouse. after a look around on the laptop it seems like there is a bug, the daft thing is it says to delete certain updates, very helpful if the keyboard and mouse drivers are gone!!!! So I reinstalled Win 7 Ultimate again without doing the updates. This time I was able to install the SDR software from SdrPlay, all went well till I installed their Spectrum Analyser software only to loose the keyboard and mouse again. By this time I was getting totally miffed, I'd already wasted the weekend sitting in front of a PC and was no further forward. I then decided to try Win 7 Professional as this allegedly didn't have the bug. This time all went well enough except for the 6 hour install, which included all the updates and the installation of SDR software. I then added Linux Mint 18.3 to the PC which took 1 hour including adding in my copied home folder and the SDR driver. After I removed memtest via the terminal so I have only 3 entries on the Grub bootloader. All is working well now, Cubic SDR on Linux flies, the other software on Windows works well although the loading time is a bit slow, annoying as the PC is a good spec and set for peak performance. So hopefully this week I can now look into the TV software side of things. The RSP1A is incredible, heard things that I have not before, may also look into DRM decoding software although there is less DRM to be heard.
Cheers.

On the subject of slow loading, are you using a conventional "spinning rust" HDD? If so, then a solid state drive will give a huge speed boost, especially for loading the OS, loading programs and any other disk intensive work.

Ht Jeffrey.
Your comment made me chuckle. Indeed I'm using a 500gb spinning disc, no rust but perhaps corrosion I might consider a SSD of the same capacity as it's unlikely I'd ever use more than that. TBH the laptop is used more than the shed PC which contains mostly hobby stuff and my documents that are small files.

480GB SSD now down to £70: https://www.amazon.co.uk/SanDisk-PLUS-Sa...=computers&ie=UTF8&qid=1534945097&sr=1-8&refinements=p_n_feature_keywords_two_browse-bin%3A3047283031
240GB at £40: https://www.amazon.co.uk/SanDisk-PLUS-Sa...=computers&ie=UTF8&qid=1534945097&sr=1-8&refinements=p_n_feature_keywords_two_browse-bin%3A3047283031 The difference really is huge. Factor of 2 minimum for OS boot, opening programs etc. I haven't actually measured against conventional HDD but I reckon 2 to 5 times faster depending on application. Obviously some things won't be much faster. Opening a single, large, minimally fragmented file won't be much faster with SSD. SSD probably not ideal for Windows before W7 as it doesn't really understand them. https://www.computerworld.com/article/24...t-for.html Notes on Linux Mint with SSD: https://sites.google.com/site/easylinuxtipsproject/ssd Notably make sure that there isn't excessive RAM swapping as it will wear out a SSD sooner than is reasonable.

Yes I always reduce the swap file on Linux. Easy to do on terminal. Mind that Linux doesn't have the fragmentation issues Windows has.

Hi.
The link Jeffrey put up regarding Mint 19 has many things that can be used to benefit conventional drives. For example I do the changes to Firefox, swap area and other tweeks. For Mint 19 I've found that having a minimum of 4gb memory is needed. Load times for Mint 19 is slower than 18.3 which in my mind is the best Mint distro by far.
Cheers.
