Hi Eddie :-)

In SpecLab you can also reduce the buffered lines in the RAM. Options > Memory. Here you can see 800 lines per default. If you change it to say 20 lines, the RAM usage will drop significantly. This may be useful on an old PC with multiple SL instances running. But you will loose the possibility to post change the brightness and contrast. This may be not problematic on a grabber, once all settings are fine. You mujst restart the program after a change from 800 to x lines, then is works.

Hi Stefan

No it wasn't an update, I control my computers not Bills mob.

I was just in the middle of this new set up on the Laptop so hadn't saved my usr. files until I was fully happy.

The desktop has been doing Stirling service 24/7 but the XYL is not happy with the cooling fans in the shack next to the bedroom. She is not as brave as Uwe's XYL, she doesn't switch the computer off in the night. :-)

I have increased the virtual memory on the Laptop, I have to see what it can cope with.

Hi Eddie,

Just disable the automatic updates (including automatic re-starting). Also save any finished SpecLab settings in a own usr file. Then close the instance and re-load it. It will work then. Even the window size will be the same than before if you close and reload the instance after all adjustments are done. This works very well on my grabber :-) I'm also running XP on the LF and VLF grabber and see no problems with 24/7/365 operation.

Hello Uwe / Henny

A report from me also, please take a look at my Grabber to see your signals, soon the traces will be gone the *********** Windows XP totally crashed this afternoon. This was the new set up using a Laptop computer results look quite good. I spent ages setting up all the instances for optimum and I hadn't yet saved them.

Some re booted windows are up, some displayed frequencies are wrong those pesky zeros again, they will have to wait for Mr Gates to honour me with another crash or I decide a re start. I would love to be paid just a Euro per hour for all the hours that Windows wastes, I would buy several more computers,

Hello Uwe,
Do you know that your 8970.022 Hertz transmitter is on the air  ?
73's, Peter - PA1SDB
Btw, I'm playing with SL. parameters in that 423 uHz SL. spectogram at my website.
I will not adjust the other 3.
