K9LJB
Amateur Radio has been my hobby since 1957!
(I started very young.)
K9LJB through the years

Roger operating 20 meter CW (code)
Above is my ICOM IC-7200 and
matching LDG IT-100 autotuner.
There's also Kenwood TM741 VHF/UHF FM transceiver and an MFJ noise
cencelling unit..
It's all mounted in a rack cabinet with a 12 volt control and metering panel at the top.
It can be run from the 12 volt power supply to the left, vehicle or battery
power.
I call it a "Shack" ( Ham radio station) in a box.
Below is my new antenna setup. The one on top is for
6meters, 2 meters and 70 cm.
Just below it is my wire inverted-V antenna for the shortwave bands.

This is my old "rig", which I still have, it's the relatively rare Kenwood TS-130V
(review) transceiver, the
low power version, with matching accessories. The keys are a Bencher paddle and a Hi-Mound 706
straight key.
My antenna is a center fed 132 foot inverted-V with the center up 40 feet,
fed with 300 Ohm twinlead.

My FCC assigned call sign since 1958 is K9LJB and I have an
FCC Extra-class license. I have been active from
my automobile on UHF and VHF voice FM as well as short-wave CW-QRP (code-very low power.
Less than 5 watts). Yes, code from the car. I have some Collins, Hammarlund, WRL and
Heathkit radio gear from the 50's (Do you remember tubes?). I also have a
collection of telegraph instruments and memorabilia. I started a separate page
for that.
Ham Radio has given me some of the most interesting and exciting times of my life.
If you are a Ham or are interested in Ham Radio drop me an e-mail.
