I was first licensed WN5CMI in May, 1962, at the age of 14. I became WA5CMI the next year when I upgraded to General. I have held an Extra Class license since 1973.

I operate AM on all bands, but lately I have rekindled my love for DXing, currently with 337 entities confirmed. The "antenna farm" consists of a Force12 C4S, an MFJ 1785 rotatable dipole, a homebrew 17- and 12-meter rotatable dipole, and a 3-element Cushcraft 6-meter beam all on a 40-ft TriEx crank-up tower. I also use a Cushcraft R9 vertical that I use for 80-, 40-, and 30-meter CW.

Current radio is a Flex3000. I love the SDR operation. For it I am using a 4-core AMD PC with 8 GB of RAM. I use K5FR's excellent DDUtil software with Flexradio's PowerSDR to select and rotate the antennas. I use AA6YQ's top-tier DXing software suite, DXLab, that integrates everything nicely.

Just completed my homebrew 3-1000Z, running up to the legal limit on 80-20 and over 1200w on the others. See pictures below.

I am a retired electrical engineer and worked at the following companies: Texas Instruments, Mostek, E-Systems, and Hewlett-Packard. I have also taught Electronics part time at Eastfield College over a 24 year span. My wife is also reitired and we are enjoying retirement very much!

73,

SX28 for sale

I am selling my Hallicrafters SX28 Super Sky Rider with matching speaker. I restored this thing about 20 years ago. The front panel has fresh paint and the tuning mechanism disassembled replated and reassembled. ALL functions work. Some of the knobs are replacements, but as original excet that the numbers are aluminum, not the brassy color of the originals. I sand blasted and powder coated the cabinets hammertone grey.The front-end cover is not original, but it fits and looks nice. This receiver works fairly well on all bands, meaning you will see S-meter deflections well over S9 using a GOOD antenna. Don't expect a 30 ft wire out the window to work well, but a resonant antenna will. The band switch feels mushy but you will find a position on every band that lines up those seemingly thousand wafers. hihi  There are four 1/4" holes drilled into the IF side for alignment (I did not put them there). All caps have been replaced (done before I obtained it), and some of the resistors that were out of range. Some work needs to be done to RF gain. It has too little range, except at the maxinum end of its control. The SX20 was designed for AM and CW. You can copy SSB, but because the AVC is disabled when the beat oscillator is engaged, you have to ride the RF gain. It wouldn't hurt to go through it again, aligning it and checking resistor values. I do have a manual.

 

The receiver looks very nice inside and out and works well, not like new, but well. Make me an offer. Low-ball offers won't offend me. Email me at wa5cmi@verizon.net.
