Please note, We are now into our new QTH in Reno, Nevada. Indications are, QRP Radio may be an operating preference, depending on what type of antenna(s) we can get up. Station is a work in progress!
Stay Tuned, More to come!
BIO Previous to 06/01/2015
Wing (Paul) Chung, originally from Providence, Rhode Island. Moved to New Hampshire in 1973. Employed as an Avionics Instrumentation Specialist. First licensed in 1977 in Ham Radio while working for this company. Crazy bunch of guys! Most of my life's work evolved around Mechanics, Electronics and CAD. I love to work on radios. I've built Knight Kits, Heath Kits and a few Foxhole Radios. Remember the "Rocket Radio"? I had a few on those going 24/7, just clipped it to the old radiator, no power necessary. Oh BTW, if you ever picked up a "Pay Phone Receiver" in those days and couldn't hear anything, it was me. I probably needed the ear piece for a project. They made great pillow speakers! My favorite radios are Icoms'. I've tried most and have always returned to Icom. The 751A is "The Bomb"! I repair, tune and align my own. I've had so many, I've lost count. It's a great quad receiver, and with a full bank of filters, it'll match anything else out there. The 735 is my next favorite. Again, I do all my own repairs and alignments on these also. I know I've owned three or four times as many of these than the 751A. Both radios are really great and will drive any amp without special connection. These radios will always be out there, long after the modern ones have faded away. Simply put, there isn't much out there in this catagory that will last 40+ years!
Moved to North Las Vegas, Nevada in 2009. Finally got sick of the Cold Wintery Weather. Sold all ham radio gear, repeaters, test equipment, etc, as I knew we were moving into a Retirement Community with Restrictions. Still working on radios though and managed to come across another 751A and 735 and fixed them up. The antenna was the challenge, but this was short lived as I decided to put an antenna into the attic space. I'm using a Cushcraft D3, because it's only 28 feet in length. You need to stay away from the Stucco (Wire Mesh). Works Gangbusters! I have since found new homes for these beauties as I've come the realize, it didn't matter how great these radios have turned out, my limitations on antennas would never let me or these radios perform to their optimum performance. BTW, I'm not a believer in changing VCO Caps. Never had to, if you can adjust it, clean it and adjust it. That's why they're called "Variable Caps"!
Pictured above is my very nice Icom 745, Fully Loaded with Filters and every Board Option. Works beautifully and very much rivals the 751A. Also shown in the photo is a very nice Icom 720A. Works beautifully and fully loaded with all filters options. Another radio in the photo is a very, very nice, collector condition Kenwood TS-830s with matching VFO-230. Gotta love the sound quality of this hybrid. Just put an Ameritron AL-811 on line, working very nicely. I like the bigger amps, been there, got the T-Shirt, but only running a 9:1 Endfed Wire here in this HOA, so didn't want to over do it. Other radios in the collection, but not shown is a couple of Icom 735s and and Icom 706MKII fully outfitted with filter and DSP. All the radios work and respond so well, that if I call CQ or answer a CQ and get no response, I have to check to see if the antenna is still up. hi hi.
My most memorable moment in Ham Radio was 1998, it was during an alignment procedure on a 751A. I was aligning and testing live, using RTTY. I wanted the receive frequency to hold whenever the "Narrow" button was pressed in without shifting frequency. The RTTY allowed me to zero in on a very weak signal with full copy. Then press the "Narrow" button and maintain the full copy on RTTY. Needless to say, I was successful with the alignment. When I actually looked at the monitor, I noticed it was actually some one calling CQ. I QRZ'd the station. He came right back to me. It was 9M0C, Spratley Island in the South China Sea. It was a Win Win! BTW, the 20 Meter RTTY Band, exploded after we signed, 73 and Good DX!
