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

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.
