Hello, My name is Victor, I am 54 years old and am married to a wonderful young lady I met 35 years ago.Kathy and I have been married for 35 years now and God bless that woman for having put up with me all these years.

 

My latest projects have been amplifiers. I have completed 5 and am finidhing a 6th. The first is a GS35B HF  amplifier for 80-10 meters. Output is about 1300 watts. The amp should possible do a bit more if I had a power supply capable of a bit more current, but this keeps me out of trouble :)

I am not really trying to "sell" these, but I would if someone wanted one.
I'd just turn aroung and make me another one. :)
If you were to gather up all the parts to make your own, you'd see that I am not asking very much for these.

 

I get my tubes from 2 sources in Europe. Dr. Alex Gaava UR4LL (faster)
and Aundrey at GSTube (Cheaper)

($1100)

 

 

I have also built a GI7B amplifier for 6 meters 
that Preston bought from me at the Stone Mountain Hamfest

I built a 2M 1.5KW GS35B amp for a freind a few months ago

 

 

Here is my 6 meter GS35B amplifier.
3500VDC .6A supply
1kw output!


($1000)

 

 

 

My 2 meter amp is finished now (10/1/2015)
It uses a GI46B tube with about 2500 VDC and has no issues running 500 watts out


($900)

 

Now I am toying with the idea of building a 432 amplifier. It's just that if I do, I will have to fix my 432 antenna (19 element Cushcraft at 60 feet up). I don't care to climb like I used to, but will if I must.

I am selling these chassis for $150 each shipped. Shoot me an email if interested.

W4VAS

 

I run Icom IC-756Pro, Yaesu FT-847 and Icom 551D radios and the above mentioned amplifiers.
I just got another Kenwood TR-751A to use with my 2M amp.
I am getting it ready to hook up and see how much power I get out with 25 watts drive.

I first got my novice license while living in Forest Hill, LA KA5VXU What a HORRIBLE CALL! I used it long enough to get my general about 2 years later and switched to N5JCH.In 1986, I got  WO5S.It was such a PITA explaining that I DO NOT HAVE A ZERO in my call, that I finally changed it to W4VAS.

I love to tinker around with stuff as much as operating, so you are as likely to find me in the back yard making a top section for my tower when I give up on finding one. or building a trap antenna, amplifier etc.

 

This is my 7 element YU7EF 6 meter yagi on a 29 foot boom.
Here is the YAGI on the ground just after I finished assembly.

The 2" aluminum boom material was 26' long and I needed 29' so I cut a 4 foot long stick I had left over from a previous project (the 12/17 antenna) and swagged it by hammering it with some 1/4" flat stock to bend in all four sides.

I used some mounting blocks that I got from DX Engineering to mount the elements to the boom. They worked out great!!

 

We installed the antenna on the 40 foot tower on 5/25/2013

The 6 meter yagi is at about 42 feet, the 2 meter yagi (Cushcraft 13B2) is at 51 feet.
The 432 antenna (Cushcraft A719B) is at 57 feet and the
MFJ dual band 2/440 converteed to a ground plane is at 60 feet.

 

I enjoy building antennas for my station and am finally getting pretty good at it.
(mostly just following YU7EF's design plans). Thanks Pop!
I have built a 7 element 6 meter (25' boom), a 5 element 10 meter on a 21' boom.

Recently, I built a 3 element 12/17 yagi of my own design.
I used the A3WS as inspiration, Coaxial Trap Design software by VE6YPto design the traps and Quick Yagi 4 to finalize the spacings etc. (always design the traps just out of the ham band so they can withstand more power)The SWR is perfect at 1 to 1 on both bands.I get very good reports even with the antenna still only about 9 feet off the ground :)

Here is a closeup of the trap (taped up to keep sun and weather out).

I finally got my tower installed and the antenna is now perched on top at about 48 feet.

 

I used a 6" long piece of 3/4" OD 1/2" ID fiberglass tube and some rg58 coax for the traps. I tapered from 7/8" down to 3/8 in 36" sections to make the elements.I can't believe how well this thing works! I have a word document with more info on my web page a http://w4vas.com ifyou want to try making one yourself. It isn't all that hard, especially if you can get 2" square tubing for the boom. I can buy it in 26' long sticks for about $60. The 6' long elements I get from http://cycle-24.com All the antennas I have made, I have used their tubing and it is absolutely fantastic stuff!

About a month ago, I decided to make a Hex beam for 6-20 meters.

I got most of the materials from Max Gain Systems

 

With the antenna literally 5 feet off the ground, I have worked all over europe with 100 watts.
I put it on a tripod on the roof (30FT) and it works fabs!

 

Future projects include

YU7EF 432 yagi
YU7EF 222 yagi
2M EME array
1KW 2M FM amp
