Today there has been some activity on Twitter using the tag #qrss.
It makes it more "live/real time" where qrg's can be changed within minutes. Propegations can be analyzed and so on.
Testing.. having fun.. you know the same old drill (8
I have been looking at Spectran running under wine on a FreeBSD box, using baudline as a reference.
Still need to port glfer to FreeBSD, it seems to working, though with some quirks

Old Sealed Pb battery
I got the 12V 17Ah battery out of my storage, but it wouldn't take charge that well.
Well I got an 50R dummy load, it got used as load, then added another one in parallel.
Charge using a regular car battery charger, then when it was full decharging using this load.
I have lost count of how many times i've done that so far. Though it seems to take longer and longer to decharge every time.
Now i have added in parallel 2 100R and one 160R power resisters.
It seems to how the power very well now.
With this load the current should be between ½A and 1A, not the highest, need to dig around to see if i have more power resistors laying around.

FreeBSD installer on USB Stick
This info was made by miwi though i found it on freebsdnews.net
And it works (8
dd if=/dev/zero of=/dev/da0 bs=1k count=1
bsdlabel -Bw da0 auto
newfs -L FreeBSD /dev/da0a
mdconfig -a -t vnode -f 8.0-HEAD-20090609-JPSNAP-i386-dvd1 -u 0
mount -r -t cd9660 /dev/md0 /mnt/iso
mount /dev/da0a /mnt/USB-Stick
cp -RvL /mnt/iso/* /mnt/USB-Stick/
vi /mnt/USB-Stick/etc/fstab and put following in:
/dev/ufs/FreeBSD / ufs ro 0 0
And it works (8

Just came across this page.
I was looking for something today and came across this page:

It is not that last time i read RAQ's!!

40m trx aka ozie
Well some time back i decided to work on making a totally homebrewed 40m trx. Well so far i'm almost done with the vxo and buffer.
I should really document the experiments. There has been made versrions of vxo and buffer.
One way to join in on building of this i by catching me on IRC on #hamradio on Undernet.
This project is also to try different approches. Homebrewing here we come.

Goodies, not lost just
Was visiting my mother the other day. I just had to look for some electronic parts. What i discovered was "new" AM variable air capacitors some with two and some with three.
They could be used for atu's maybe other antenna related projects.
