There is something to be said for a chain saw CW note. You stand out in a crowd. And as for your station, have you considered an Alexanderson Alternator as a upgrade to your spark station? They are t
There is a lot to be said for an antenna as a resonant circuit. One of the very early SSB patents did just that. They sliced off the carrier and opposite sideband at the antenna. Now if I can just re
We're cruising toward the 100 year anniversary of SSB. It definitely qualifies as older technology. It was the famous John Carson patent for SSB filed in 1915 that used the antenna circuit for more t
Never left AM -- that's Don, K4KYV's line and I suppose mine too except like many I left ham radio for decades. I use my OMNI VII as RF drive for my 300 W home brew class E now and often listen on th
Mike, Please enlighten us with the settings. What power level do you run on the OMNI VII? How about EQ? When I tried it once just recording using a dummy load I thought I might need quite different E
The little decorative end pieces on the sides of the front panel of my trusty 238 are broken. The are little brown vertical pieces of plastic maybe 5" long, tapered, held on with little clips. I see
Here we go. New stuff to keep the water off our ladder line. This may ruin the long standing joke about antenna wax. The video is quite amusing: http://www.chonday.com/Videos/NeverWet-arrives-in-stor
Anyone familiar with the Hercules II relays? Mine now keeps the antenna disconnected from the transceiver (O7) whenever the amp is on. Pulled the amp on to the bench and sure enough IN doesn't connec
Nice write up and pictures, Rick. I've saved it in case I need it. This must be International Hercules II Relay Week. I just solved a problem similar to yours caused by a different failed relay. When
How big are the ground losses? Are they the difference between an EZNEC prediction over perfect ground and what it says over average ground assuming average is what you have? Is it the difference bet
That's what I've been doing, modeling antennas at different heights over different grounds. But the pattern changes too. Dipoles become more omni directional. That by itself will change the maximum g
This is the quote I've wondered about. It's from Bob Orr, W6SAI's, Antenna Handbook. "Antenna radiation resistance is influenced by antenna height. Assume the antenna is an 80-meter dipole. A common
Steve, Where are you getting losses out of EZNEC? I did re-run the the dipole at 25 and 55. As expected, all sorts of things are different. But where are you reading losses? Jon
Roger, I'd go with PTFE (teflon) based grease. I haven't re-built a Ten-Tec PTO but I have re-built boat anchor PTOs. Lithium grease dried up after a few years and became an anti-lubricant. I was puz
