DOES ANYBODY REALLY KNOW WHAT TIME IT IS? Since the establishment of Coordinated Universal Time (UTC) in 1972, 22 leap seconds have been added to keep atomic time in synch with the rotation of the Ea
Really interesting concept and a worth while item if it works. But, I have a few basic thoughts about how one would go about such a pair of pre-amps but am probably way off base so I'll pose the ques
Some of those among us with graying and/or thinning hair may remember of W4EGK, Joe Batchelor. Joe was the lead engineer at Central Electronics, who's noted for the design and development of the broa
This is what more I now know about W4EGK, Joe Batchelor SK and the Central Electronics rigs his was involved in. What a pioneer and a giant of a man. de KD4GT -=-=-= The Central Electronics Company O

I had a "driver" from an MRI machine that I used for a 6m amp. This one was built by ETO (yes, *that* ETO that builds the Alpha series of amps). I also had some of the documentation for the whole sys

The lab in Newington doesn't have multiples of the test equipment therefore the same gear has been used for many years. (Did you see the note on the bottom of page 15?) I'm not sure of this however I
While I can't afford a shiney new Orion (unless someone really unsatisfied with the lack of PTT to key it wants to donate theirs!), I did go looking at the heilsound website to see what Bob puts into
For examples of what the BPL sounds like, goto: <http://www.arrl.org/tis/info/HTML/plc/> on the ARRL web site. Ed Hare & crew have done lots of research on this pending disaster to all HF communicati
I recall my father stating that fishing lures are designed to catch fishermen and not fish. I suspect that a color display would be designed to catch hams and not ham signals. Personally, I am glad t

Now this might get lots of offers. Most will probably volunteer to store the gear in their shack - "just so its in a climate controlled environment." Most will also offer to "test" the gear on a regu
VHF/UHF Contest - Jan 2002 Who is this Murphy guy - And when did he take an interest in VHF/UHF radio? The Sweepstakes were coming up. HUM had often thought of doing something close to town. Maybe we

This is the second peice of test equipment any ham should have - the first being a good DVM (VOM for us old guys!) I have the early MFJ-259 but it still works well. The later units (259B) give you th
It's RF related and that's close enought for me!!! As one of those 'radio guys' at the tower sites, I see these GPS antennas frequently. Paging services use them for syncronization of their transmitt
