Site survey

Another antenna

I forgot that I have my Mosley RV-4C vertical (10-40 meters and I have the 80 meter coil on it).  The base of the antenna broke off quite some time ago.  I can get a new base for $50 from … Continue reading

So far so good

The 40-meter hamstick dipole is doing surprisingly well being it’s close to power lines.  I’m hoping to get a set of 80-meter hamsticks and relocate the antenna further in our property, away from noisy powerlines.  If the finances allow, I’d … Continue reading

The shack

I finally took a picture of the “operating position” in my tiny shack.  It’s an 8′ x 10′ room so there’s not much room in it. The 706MKII is sitting on a shelf to the left in this picture.  Seen … Continue reading

Configuring the serial port under Linux

I discovered that this new computer has its physical serial port at address Ox3F8 but on IRQ 10.  I wasn’t sure how to correct this problem so I dug deeper.  This is specifically for Slackware Linux but this should apply … Continue reading
