Help: How can I Migrate Microsoft Works 2004 Logs to New Program

November 5, 2011

K3CDQ asks: I have an old computer with lots of 2002, 3 and 4 software on it. I have thirty years of ham contacts logged in a data base that I worked up using Microsoft Works 2004. I now have a new computer with all 2010 and 2011 software on it and running XP. I … Read more

Installing Ground Rods the Easy Way

July 26, 2018October 5, 2011

Impact Drill the Rod by KJ4FAJ and brother

Ground Rods… so easy a pre-teen can do it. Presented is a method learned from other hams on how to install a ground rod with minimal or no hammering. Using a watering can, even children can sink an 8 foot ground rod into the ground. All it takes is water and time.

Hexbeam Gets a Spine

Aluminum 8 ft. 1.5" dia. mast with 1/4" inch walls.

My G3TXQ Hexbeam gets a new metal backbone to accommodate a VHF beam antenna. A byproduct is a much stronger antenna assembly than the common Hexbeam approach.

‘UHF’ Connector Test Results

January 11, 2017October 3, 2011

Real measured data reveal the UHF (PL259 and SO239) connectors have real limitations.

Lab Tests: SMA, BNC, TNC and N Connectors

May 28, 2016August 6, 2011

Lab tests show post WW2 connector designs perform exceptionally well up to 500 MHz. The SMA, BNC, TNC and N connectors are great.

PL-259/SO-239 Return Loss and Attenuation Test

May 28, 2016August 3, 2011

We pit the PL-259 (and SO-239) against more recent connectors. This is the list of contenders plus a description of the test setup.

Pretty Lousy? (PL) 259 Connectors

May 28, 2016July 29, 2011

The PL259/SO239 (aka UHF) connectors have harsh critics and religious defenders. Questionable measurement techniques complicate matters. Let’s clear things up.

Virginia Summits On The Air

February 24, 2012February 11, 2011

After some Virginians volunteered to research the mountain peaks in the Commonwealth and see which ones are sufficiently prominent to qualify for the Summits on the Air (SOTA) program, we now, as of Feb 1, 2011 have 542 peaks from which to operate a ham station.

If you are a hiker and a ham, the Summits on the Air award program is for you. Originally organized in England, SOTA has become very popular in Europe for both hikers and summit collectors. Operators in the United States have caught on; Volunteers are working feverishly to add US peaks to the growing number of valid SOTA summits.

Virginia is now proudly represented in the W4 area.

Check out the Virginia peaks right here in this web domain.

43 Foot Vertical Pops a U-Bolt

December 14, 2023December 15, 2010

The top U Bolt holds while the bottom just hangs there.

Another title might be… “43 Foot Antenna, the Tilting.”

NOTE: UPDATE AT END OF THIS POST

We had a big blast of cold air come down from Canada last night. Temperatures reached the teens and winds peaked at 50 mph. No problem I thought… “My DX Engineering 43 Foot Vertical has been up in weather like this since 2008 and does exceptionally well.”

The morning was busy gathering up blown away things and mounting a search and rescue of my car cover. Often this car cover sweeps around the house so I walked out back.

My eyes scanned the back yard for the cover. HORROR! I looked up to see a not so vertical antenna against the December backdrop of a cornfield and morning sky. Figure 1 reveals my shock and awe moment…

Dallas Cowboys, DTV, Wife and Hex Beams

So what do the Dallas Cowboys, Digital Television over the air broadcasts, my wife and the Hex Beam have in common…

You’re probably thinking…

“Man… John has lost it. He’s blogged one post too far… On Halloween afternoon too…”

Hang with me for a moment.
