Antennas at KE5PRL

I have two antennas for receive/transmit and a long wire for receive. The receive/transmit antennas are a 43 foot vertical and a G5RV. The vertical is attached to my rig (Ten-Tec Orion II) as antenna 1 and the G5RV as antenna 2. This is important because only antenna 1 can be tuned by the internal tuner. The vertical will tune on all bands except for 160 M and 80 M. The G5RV can be attached to the rig as antenna 1 and it will tune to 80 M but not 160 M. When tuned, both antennas may present a low SWR to the rig but are so poorly matched to the band that my output power is quite low.

Blinking LED with 555 IC

We talked about kits at the last W5UMS club meeting. That made me want to smell some solder smoke so a few days later I built a simple 555 blinking LED just for the fun of it.

Ten Meters Open

For the first time since getting my ticket ten meters opened up. I made several PSK31 contacts in the US and a couple in Japan. This weekend’s CQ Worldwide DX RTTY Contest could be a really good chance to make a few more contacts on ten meters.

Space Shuttle.

I watched the last Space Shuttle landing this morning.  Hopefully the next phase of space exploration will be as successful.
