Ham Member Lookups: 14211


I was licensed in 1959. My interests include DX, contesting and building my own antennas and hf/vhf equipment. I even built a full featured 160-6 meter transceiver (the HBR-2000).  If interested you can see it on my WEB page at http://ve7ca.net under the HOMEBREW section.  I also have a Ten-Tec Omni VI+ for contesting and digital communications.  

I am presently using three Extended 20/15 Meter Double Zepps.Two are  fed with 74ft 6 inches of 450 ladder line and the third fed with 600 Ohm balanced line.   No antenna tuner needed from 20 to 10 meters.  For 40 M an extra 33 ft of ladder line is add an antenna tuner is not needed.  An antenna tuner allows use of 80 and 30 meters.  For 160 meters one of the 20 Meter Double Zepp's ladder line is tied together and fed again ground. The whole system is remotely controlled from my ham shack.

I am also very active on 630 Meters. Yes, 475 KHz with a homebrew trarnsverter followed by a 80 Watt Class D/E amplifier which is 85 % efficient.  The 630 M antenna uses all three Zepp's feedlines tied together in series with loading coil.  Using WSPR I have been decoded by VK4YB which is amazing as my ERP (effective radiated power) is only one watt.

I am also interested in restoring vintage ham radio equipment. I have restored a HQ120X, HQ110A, COLLINS 51J-4 and a Viking Ranger. I have worked lots of DX on CW and on AM many QSO's to the east Coast with only 40 Watts output power from the Ranger. Re-living my youth?




















You are invited to check my web site http://ve7ca.net, for details about my homebrew projects, recent 630 Meter activity, 160 Meter terminated receiving loop and noise canceller as well as a summary of my ARRL publications.

Recently I began using MDSR (Modulation - Demodulation Software Radio) system that was featured in the QST by Alex Schwarz (VE7DXW)  I installed the MDSR converter board into my Ten Tec Omni VI+ to produce an IF of 12 KHZ for digital processing which is demodulated by MDSR software.

Details how to build your own MDSR station with your existing radio can be found at MDSR Website.

RF-Propagation at VE7CA is updated below when MDSR is activated.
