One week later...
QRV: The station has been put back together, mostly. The K3 is connected to the old Dell desktop running XP, the Flex 1500 to the laptop which I wiped clean and installed a fresh copy of Windows 8. Everything seems to be playing well together. One week back on the air and two new ones in the log: St. Helena and Indonesia.
Flex and DM780: Using VSP Manager, I was able to get the rig talking to HRD but still need to configure VAC to get DM780 working with the Flex. Either that or make a set of cables to get audio in and out of the rig. Much rather keep it down to a single USB connection, though.
DXCC!: The Awards tab in HRD kept telling me I had 80-something countries confirmed. Then I noticed a couple that were not checked, even though I know I had them. So a careful recount by hand ensued. Lo and behold, I have 102 confirmed. Only took 26 years of halfhearted card chasing.

I'm back.
The new toy in question is a Flex 1500, something I've wanted for a while just to get dip my feet in the SDR pool. I had a chance to play with it a bit last night after finishing the coax run and setting the Tarheel up in the backyard. Initial impression is something along the lines of "HOLY CRAP!!!!" I envision this rig to be dedicated to digital modes. No intention of giving up the K3, just wanted to see how green the grass is on the other side of the fence.
We sat in on K5GJ's talk on SDR and the new 6000 series from Flex. Pretty amazing stuff they're doing down in Austin...
The Elecraft booth was hopping, and I lusted over the KPA500 amp. And the KX3. And probably would have picked up a K1 kit had I not already dropped $700+ on the Flex. Maybe next year.
Got to spin the knobs on a bunch of rigs I'd up until now only seen in QST -- TS-990S, FT-3000, FT-1200. All handsome rigs.
Did I mention I passed my Extra Class test? [Fist pump.]

Rumors of my death have been greatly exaggerated...
I've been QRT (both radio- and blog-wise) for quite some time as the XYL and I have been planning and, over the past week, executing a move from Robinson to the charming little town of West, TX -- that's West (comma) Texas, population 2,690, which despite the name is nowhere near "West Texas" but just a dozen miles or so north of Waco in the central part of the Republic. According to the FCC database there are 18 licensed amateurs in West, including your faithful correspondent.
The new QTH is an old but freshly renovated 3 bedroom house with a detached garage and (praise Jesus!) trees, giving me antenna possibilities that did not exist at our suburban-hell duplex in Robinson. There's a tripod already on the roof; it's not exactly heavy-duty but it should be adequate for a vertical. Whether I'll put the Cushcraft R7000 back into service or simply mount the Tarheel on the roof remains to be decided. One of my priorities is to at least get a dipole strung up for 6/10/12 meters. Not yet sure if there's room for an 80m wire.
The shack/office is about the same size and layout as at the last QTH. There's a large walk-in closet that I will use as a library to store some of the 8.6 million books that I seem to have acquired over the years and which I hope to have moved for the last time. I no longer have a loud central air conditioning unit outside the window of the office; however, I now live across the street from the main Union Pacific train line that runs through the middle of the state. Being a lifelong fan of model railroading but never having the room, tools or skills to build the N-scale layout of my dreams, I can now enjoy a 1:1 scale road with regular trains that shake the entire house about a dozen times a day like a coin-operated bed in a cheap motel. Must remember turn the VOX off when I'm not at the radio.
Since we're still living out of boxes it may be some time yet before I can get the shack reassembled, antennas installed, and return to the bands -- needless to say, the IARU HF contest is going to have to get along without WW2PT's big signal, and the IOTA test in a couple of weeks will be a long shot, but I fully intend to be up and running in time for NAQP in August.

My NRD-525 and other goodies are on the block...

Fiscal realities are forcing me to sell off more of my JRC collection, this time a mint, new-in-box, untouched-by-human-hands NRD-525 HF Receiver along with likewise mint CMK-165 VHF/UHF Converter and CFL-232 500 Hz Crystal Filter. All three now on eBay as separate auctions.

WebSDR

My bud Ulis K3LU just turned me onto the WebSDR project. Spent a little time this morning listening to W4MQ's station, which is set up for 160m, 40m, and 20m. Very impressive -- I've steered clear of online remote receivers in the past because they were typically a single radio controlled by a single user at a time (or, worse, by multiple users continuously changing frequency and mode, making it little more than an exercise in hi-tech uselessness). But this is different -- a true server that lets multiple people listen at the same time on whatever band/frequency/mode they want, completely independent of one another. Way cool.

NCJ: What's the Best Contest Rig?
The March/April 2010 National Contest Journal arrived yesterday, torn and tattered as always (thanks again, US Postal Service!), and with it the results of K3MD's informal poll of top contesters asking, "What's the best contest rig?" It's by no means a scientific survey, nor all-inclusive, but many of the Big Guns you'd expect participated. Sunday, February 28, 2010

While I was distracted...

Other than working ZL2PW on 40m during a bout of insomnia in the wee hours the other night, I've mostly been QRT all week. However, I left the K3 tuned to 7035 as I usually do just to see what might have been. I wish I hadn't looked.
