Up and Running in Guatemala

After an interruption in ham radio activities and blog entries, I am back on the air, more or less. The interruption was due to several months of planning and executing a move to Guatemala and then getting settled here in my new digs and setting up a basic radio shack. At the moment I am only using a 26 foot vertical wire supported by a tree so my signal is not very good but I’m out there on PSK and Hellschreiber. You can usually find me evening and nights from 7070 to 7074, signing TG9/KW2P. Give me a call.

Once I collect the materials I plan to put up a 270 foot vertical loop. I have some tall trees here that will support a vertically oriented 80m full wave loop. I’ve had both vertical and horizontal loops of that size and they worked great so I expect good results, especially in the tropics where QRN can be a problem. The loop should improve things drastically but getting the materials down here takes some doing.

HAARP Moon Echo Experiment

Tonight, the HAARP transmitter in Alaska was used to direct exceedingly powerful radio pulses (around 4 Gigawatts effective radiated power) at the moon at a frequency of 6.7925 MHz and I could easily receive the echoes from the two second bursts here on earth with my amateur radio rig.

Wednesday Night 40m Hellschreiber Net

40 meters was being ornery tonight at net time of 9 PM EST. Here in West Virginia I had no copy, no signal at all on net control or anyone else except I had about a 50 percent copy on WB2HTO. I saw the name Leslie go by, and I believe I saw a QTH in AL. At 9:35 PM EST I checked in again and the band had greatly improved. I had net control, about 90 percent copy on WB2HTO but work got in the way and I did not have time to check in.

I’ll be there next week unless work overrides my plans. Thanks to W8LEW for running the net.
