VK6HV and AA6SN

I'm sorry to say, but I've pretty much stopped QSLing. But if your keen to confirm a QSO with me, please QSL direct . Log into QRZ.com to get my address. I will return a card 100%.

OK, by popular demand, I now use eQSL.

My profile picture circa 1986: My first shack as a Novice class callsign KB6PCD while living in La Verne, California. It's all Heath Kit gear. SB102 transceiver, digital display, SB200 linear amplifier, 2 meter transverter, station monitor, matching speaker, SWR meter and 2 meter FM transceiver. But the real joy was building my first home brew rig. It was a 40 meter crystal controlled transmitter on 7.125 Mhz with a 6AG7 Pentode for the oscillator and an 807 Beam Tetrode for the PA with a whopping 30 watts out!

I do more listening then transmitting these days. Latest project is adding 6 meter elements to my 3 element tri-band HF yagi. That's correct, it actually works and appears to work very well. I also enjoy 2 meter tropo as I live in a known "hot spot" here on the north west coast of Australia. During the summer, there are numerous 2 meter tropo opening to Indonesia, Cocos and Christmas Island to the north-west and Exmouth to the south.

My Grid Square here in Australia: OG89nh

EARLY DAYS

As a Technician class, N6RLG in Hesperia , CA. circa 1987. Still running the old Heath Kit gear. Changed from the Butternut all band HF vertical to a 3 element tri-bander HF yagi! Much better signals now on 10 - 15 - 20 meters! I also used a small 2 meter home brew yagi for local 2 meter chit-chat.

 

 

As an Extra class, AA6SN in Hesperia, CA circa 1989. My two matching home brew amplifiers I built. Left - single 4CX250b on 2 meters. Right - a pair of 813's on 10 - 80 meters HF. The rigs where a Kenwood TS140S on HF and a Kenwood TR751A all mode on 2 meters. The little silver box with the green LED was my SSTV Hamcom converter. I was probably running the K1BC "Vester" systen in Microsoft GWBasic or JVFax for SSTV in DOS. Antennas were the HF tri-bander on HF and the Cushcraft 17B2 two meter boomer for 2 meter SSB. I also used a MFJ1278b multimode TNC for Packet radio when Packet was all the rage. This was about the time I got on the 160 meter band with a trapped dipole for 40 - 80 -160. I also installed 160 meter functionality into the 813 amplifier.

 

 

As AA6SN in Hesperia, CA. circa 1990. The tri-band HF yagi and the Cushcraft 17B2 two meter boomer in the back ground. I can remember listening to some Canadian stations on 2 meters bouncing signals off the moon one night just after the moon was above the Eastern horizon. I tried, but didn't make contact with them, even with hundreds of watts output, but is was still a blast to listen in with just the Kenwood TR751a, homebrew 4CX250b amplifier, Cushcraft 17B2 boomer antenna and a 2 meter pre amp.

 

 

AA6SN in Hesperia, CA. circa early 1990's. Still using the tri-band yagi on HF but now using a small Cushcraft 10 element yagi on two meters. Now on Amateur Television with a 429 and 434Mhz. ATV transmitter and a 902 - 928 Mhz. ATV receiver.

Also, the starting of my infatuation with wind power as seen in the left side of this photo. Built with 2 old IBM surplus tape drive motors, a Volkswagon left front spindle, home made tower, home made 3 blade propeller, home brew electronics and regulator. Output 12VDC at 10Amps. Gosh, I wish I still had it.

The current antenna setup at VK6HV. Australian made TET-Emtron 3 element HF model TE-33 tri-band yagi with three 6 meter elements added. It really does work! Diamond 2 meter/440Mhz. vertical and a 40/80 meter trapped diple with extra L in the 80 meter portion to reduce the overall length to fit in the backyard. A pretty simple setup, I can normally talk to anyone I can hear.

 

 

A home brew PICAXE-18M2 repeater controller. Programmed in BASIC. 

 

 

A home brew OPC-478 interface for programming my ICOM-208H radio.

 

 

A home brew PICAXE electronic keyer for my Vibroplex single paddle key. Just a space saving idea. About 5 to 40 WPM? Programmed in "BASIC". Mode A and Mode B Iambic keying with 2 outputs. A 2N7000 MOSFET and a very quiet high speed reed relay.

 

 

Another view from the side.

A smaller MKII version. The keyer without the high speed reed relay.
