I have been a HAM since 1972. From 1972 until11/2007 I held an advanced class license - WA1SFU.
I upgraded to Extra and obtained my present call (W1JWC) around 11/2007. I picked this call since it has my initials in it.
In 1971 I obtained my First Class FCC License and worked at a few radio stations as a broadcast engineer and Chief Engineer.
In 1974 I went to General Electric as an Electronic Engineering Technician. I continued my education in the evenings and worked my why up to a Senior Electrical Engineer for General Dynamics as an analog/power designer.
In January of 2011 I suffered a hemorrhagic stroke due to an AVM within the brain. I have not been back to work since. It was a great job and really miss it.
I went to Beth Israel in Boston Mass in July of 2011 and had a Cyber Knife procedure done which focused radiation at the AVM from all different angles. Two years time will cause it to close off reducing the possibility of bleeding again. The two years has passed and the AVM is gone.
I still have some motor control and cognitive issues that keep me from returning to work. Life can be short so make the best of what you have!!!!
I Enjoy, HF, VHF and HF SSTV
At present I have five antennas in use:
160m Full Size Loop
G5RV (Double size- 204ft acroos top by 68 ft 450 ohm drop)
43 foot vertical ( DX Engineering version)
40M Inverted V
Hexbeam ( K4KIO version)
My main radio is the Flex 5000A with a Large condenser microphone.
I have a Berhinger XR12 mixer/effects,.
I also have an:
Icom 756 Pro 3
Yaseu FT1000MP MK5
My Amplifier is the Ameritron ALS1300 Solid State.
My station is setup to operate remotely over the internet.� I have used it from all over the US while on travel for work. I can use either a laptop, my Android tablet or my Android Smartphone to connect back into the station.� Its a lot of fun!
I can remotely select one of the five antennas listed above and also have the capability to rotate the Hexbeam via remote internet operation when operating remotely.
The Amplifer is setup to band switch with the radios and I have the capibility to turn it on/off and or standby via remote operation and of course being solid state no tuning is required.
Below is a picture of my K4KI0 Hex Beam I installed in March of 2010.I had just finished assembly and was checking SWR before installation on the mast.
Assembly was only about 3hrs from start to finish and everything went together perfect.
The mast is mounted to my deck in the rear corner using a 4.5 foot Glenn Martin tower. The tower is set up so that if I remove the rear lag bolts on the back side facing the siding, I can thentip the mast over the edge of the deck to install the antenna. The rotor is mounted on the tower brackets rotating mast and antenna. Rotor here is a Yaesu G-450A with a MDS RC-1 PC control via RS232.
Here is a shot of the antenna tipped over the edge of the deck ready to be raised to a vertical postion. Raising was performed by throwing the upper guy ropes over the house roof. I then had help from Tom ( W1DDW), as he pulled the ropes I walked the mast up at the same time. It was a piece of cake.
Here I am pinning the lower and middle mast sections together with a 1/4-20 bolt.
The Hexbeam works great on all bands including six meters. The match is almost flat across all bands so the need for an antenna tuner is minimum.
Below is my 43 foot vertical from DX Engineering. I presently have 32 radials, each about 65 feet long that are laying on top of the grass and stapled every 20 feet.
The line running across the top of the garden is theXYL's clothes line.
Hey had to let her have something in the yard!! There has to be a way to turn this into an end fed zep!!!
The antenna is modifed with a base loading unit that I designed. On 40M and above the antenna operates as designed from DX Engineering. On 80M and 160M I use the base loading unit to resonate the antenna on both bands. Performance on these bands is greatly improved by doing so. The base loading unit consist mainly of a tapped loading coil and relays which I can control from in the shack or remotely via the internet.
Inside photo of base loading unit. Hand wound tapped coil with power control relays used for RF switching. The original UNUN balun from DX Engineering is still used either all by itself for 40M and up or in conjunction with the loading coil for 80M and160M. The relay next to the balun switches it directly to the antenna or to the loading coil input. The other two relays are used to select the proper output taps on the loading coil depending on 80/160m selection.
160M power has to be kept below 400 watts otherwise the relay will arc from the contacts to coil due to the very high resonance voltage present on 160M. I am presently searching for better relays.
The shot below shows the G5RV and 160M Loop. TheLoop is hard to see but it is mounted off the TV antenna mast.
I would like to thank both TOM (W1DDW) and Frank (WT1B) for all the help in getting my antennas up.
And this is me taking March 3, 2013
