Encouraged by my friend Steve, VE7SL I recently built a tranmitter for our new Canadian amateur radio band, 630 Meters. Check Steve's blog out for some interesting experimenting: ve7sl.blogspot.ca/

I used GW3EUP's design for the transmitter . Here is his URL,


The follow picture is my 9 MHz CMOS VFO which is divided down providing a tuning range of 472 to 490 KHz. The transmitter is build in an old Northern Electric AM exciter chassic which has a nice reduction gear for the VFO.

The amplifier is composed of two parallel IRF510's run in class E followed by a low pass filter. At +12 Volts it puts out 14 watts.

The following photo is a combined 160 Meter and 630 meter matching system. The 630 meter loading coil is tuned with a variometer and it allows tuning to resonance my 70 feet of 450 ohm twin lead feeding a 40 meter quad that acts as a top hat. We are allowed to run 5 watts ERP on 630 meters but my meager 14 watts power output and inefficient antenna likely produces only 0.5 watts ERP. Amazingly I worked K7CW crossband. He was transmitting on 160 meters and I on 630 Meters. He is located near Seattle WA. When either 160 or 630 meters are selected one relay shorts the feedline together and the other relay selects the correct matching network for either 160 or 630 meters.

The following photo is my prized boat anchour station which I refurbished. I thoroughly enjoy operating these old tube radio's. The old AM transmitters have a rich clear sound which is so pleasant to listen to. On 15 meters I often find hams hanging around 21,400 to 21,440 KHz calling CQ on AM and then working them with only 30 watts ouput power. Having to re-learn to use an old Vibroplex bug after using an electronic keyer for over 40 years has been a challenge, HI.


I was 16 years old when I obtained my ham radio licence. My First Station's call was VE7BGE. After high school I attended Room 19 in the City of Vancouver, BC and obtained my 2nd Class Commercial Radio Licence. Upon graduating I obtained work as a commercial radio operator at a Loran Station then as a radio operator and weather observer at Spring Island, BC off the west coast of Vancouver Island. I was later transferred to Smithers BC, then served as a commercial radio operator for one year at the worlds most northerly city, Alert NWT.

After returning from the Arctic, I was transfered to Terrace BC and finally to a Canadian weather ship named "The Stonetown", stationed off the West Coast of British Columbia. Here are a few QSL's that I sent out when operating from the above mentioned locations: First/Maritime-Mobile/Alert-NWT/Today.

After a particularly bad storm while at sea on the Stonetown I decided to return to school and enrolled in general sciences at the the University of British Columbia,(UBC) located in Vancouver CANADA. While at UBC I was an active member of the university ham club called HAMSOC: FD 1967/Reunion-1986/1992/1995. During my second year at university I met my wife. We were married in 1969. In 1973 we moved to Cranbrook BC and I was active with a Heathkit Station chasing DX and building solid state QRP rigs. Heathkit Station.

While living in Cranbrook BC I obtained my flying licence. I often worked 2 meter aeronautical mobile while flying. At an altitude of 12,000 feet you can work a long ways on 2 meters. Photos: My brother and I by an old Cessna 172 visiting our cousins on their farm in Saskatchewan/My father-in-law, VE7BEH now SK, and I preparing for a flight over the Rockies in our 1977 Cessna 172. While living in Cranbrook I was happy to receive my two letter call sign, VE7CA.

In 1980 we moved to North Vancouver,BC and purchased our present home. We have one daughter and two sons and now blessed with six grandchildren, 2 girls and 4 boys. Recent pictures of me, Markus Hansen, VE7CA and our six grand children. Since I retired in 2011 I have a little more time for ham radio.

Following is a picture of my present operating station with my homebrew HBR-2000! The HBR-2000 is a home built, 160 to 6 meter CW/SSB & Digital Hi-Performance QRP transceiver. Under the operating desk is a homemade 160-6 meter, 100 watt amplifier and power supply. You can find more information regarding my homebrew amateur radio projects in the menu above. On the shelf above the HBR-2000 is a 40 Meter direct conversion transceiver (W7EL design) and the DCP-10 6 meter direct conversion CW/DSB transceiver which you will also find described in the Homebrew Page in the Menu at the top of this page.

I continue to be active operating mostly CW, chasing DX, and entering contests. I have a strong interest in antennas and have published 4 articles on antenna designs that I have developed. I have also had anticles publised in QST and QEX. See the above menu for further details regarding my homebrew amateur radio and antenna projects.
