Re: LF: 500kHz Grabber.

Rik,

Reduced the SpecLab capture to 40% quality but they still look quite good. In fact the clip I sent via your last mail re: your QSO was cut from one of those captures.

The general size range is from 100 to 125kb which is about half the previous capture size so could be OK at that. I have also found that using the multi-colour palettes (I was using Sunrise) increases the file size. I am now using my own palette edit again (black to yellow), it seems to give a good contrast.

BTW, not familiar with _javascript_ either :-((

Gary,

indeed the process should be automated.
But as you mention SpecLab has a selectable compression rate for the jpeg screen captures.
The upload steam could be further reduced by uploading only the "recent part" of the screen grab and composing the picture on the web site from a number of grabs. Should be possible with _javascript_.

Rik,

Thanks for your suggestion. I am not familiar with Corel Photo paint  & it does need to be automatic as I can't spend time editing each  upload ie. two at 10 minutes & 1 at 1 hr. I am trying reducing the  JPG at capture time by lowering the JPEG quality percentage on  SpecLab. I have taken care of the G4JNT beacon upload by using *.png  & the file is only a few kb's rather than 10's of kb's using *.bmp &  uploading at 1 hr intervals instead of 15 minutes.

Gary,

maybe more compression in the jpeg.
Using Corel Photo Paint I could reduce the file size to 50% with  little visual impact.

Hi All,

Sorry to have to announce that my grabber is inoperative at the moment.

It seems that I have regularly exceeded the daily quota set by the   ISP/web site provider. I have been transparently placed in   "restricted service" which is only allowing about 5   uploads/downloads each day. I expect that it will take some time for  my average to come down sufficient to allow my regular uploads again.

Also I will have to make the upload file sizes smaller & less   regular so as to keep within this upload limit.

I will post a notice here when all is running normally again.
