As I made my way through the security line, the battery was naturally flagged for further inspection. Eventually the security folks cleared it, pending approval from the airline.

DX Monster antenna
Even with the current solar cycle as it is, I am making more DX contacts now than I ever have over 25 years. Part of my luck must be given to the new digital mode called FT8, but I am also of the mind that my antenna is doing a fine job.

Colorado (W0C) SOTA Activators
Here’s the SOTA activator scores for Colorado (W0C). I have to admit that I like checking this to see how everyone is doing. Some of it is friendly competition but mostly its enjoying the accomplishments of my fellow SOTA enthusiasts.
We’ve got 10 “Mountain Goats” in Colorado now, with 1000 or more points. Carey, KX0R just never stops activating. It seems like he is out there on a summit every day. My friend Brad WA6MM just made “Mountain Goat,” by activating only Colorado summits, never repeating any, with many difficult climbs. Note that his average points per expedition is 8.65, higher than any of the other MGs. (W0CCA comes close at 8.21) Congratulations, Brad!
It looks like K7PX and KD0YOB are next in line for Mountain Goat, while I am still a ways back. My hiking partner Joyce/K0JJW is coming on strong, having accumulated 200 points. I just cleared “half a Mountain Goat” at 500 points, so I requested a certificate for that accomplishment. At my current rate of progress, I am about 2 years away from Mountain Goat. I keep telling myself to be patient, keep at it and (most of all) enjoy the journey.

Complete Version: On How NCIS Maligned the Amateur Radio Service
Some of you wanted to see the complete version, uncut, of this video in which I discuss the differences between CB and the Amateur Radio Service. This is in response to the recent episode in which the NCIS writers missed a great opportunity to discover the vibrant reality of the current amateur radio service in the United States of America.
The previous version of the video was prematurely cut short by just over three minutes. This version includes that ending. I also remove some of the low-end rumblings from the vehicle. This version should sound a little bit less annoying. Hopefully, the quality of the video is sharper, as well. This version was edited by Adobe Premiere CC 2017.
I appreciate the many comments, views, and shares. Please subscribe, too!

Resistor deals just get better!
Last time I looked over selling websites it was a 2000 deal, but I have now found a couple of 2500 1/4W 1% metal film Res bargains.
First one is the Chinese site Banggood @ £7.42 (US $9.51) plus a 12% voucher popped up, which you have to bop in at the time of placing the order, taking the price down to a penny pinching £6.53

I then run the details through ebay and a similar package came out at £6.99 ($9.18):

On How NCIS Maligned the Amateur Radio Service
EDIT: Please view the NEW article, in which the FULL VERSION of this video exists.
I’ve been reading some of the chatter regarding the NCIS episode in which they incorrectly portray the amateur radio service. I thought I would make a video (vlog) and express my thoughts.
I use my new headset mic to make the video. If you have a few moments, please check it out, and let me know how the mic sounds.
Of course, share your thoughts on the NCIS thing… thanks!

Yes, the video gets prematurely cut off. The editing software on my cell phone chopped off the ending, and I did not realize it until after it posted the video. I’ll record a follow-up video that includes the ending thoughts, but in a new vlog edition.
Cheers and 73 de NW7US

An Old Friend Found
Several years ago, like many other hams, I was stricken with 'Tuna Tin fever' and purchased a Tuna Tin II kit from the Norcal QRP group.
Escaping the summer heat a few months later, I put it together over one weekend in July. As it turned out, it was probably the best $13 I ever spent on my hobby.
I fired it up the next morning and put out my first 250mW 'CQ' on the 7040 KHz 40m QRP calling frequency. Back then, 7040 was ground-zero for forty meter QRP fanatics and there always seemed to be folks monitoring while working at the bench on their latest project. Given the time of day and the mid-summer propagation, I really didn't have high hopes but I was immediately answered by KJ7AN in Dallas, Oregon who gave me a 579 report!
Over the next three days I worked several more stations in Oregon, Washington, Idaho and even California. I was truly delighted with the little rig's performance but assumed that my pint-sized signal would probably not go much farther than the nearby western states and maybe, if I was very lucky, a few more Californians.
All that changed early on the morning of August 6th! About an hour after sunrise, my tentative hand-keyed 'CQ' was answered by Steve, NØTU in Colorado!! Steve had been enjoying his morning coffee while the quiet hiss of 7040 in the background was broken with my very weak 'CQ'. We had a good solid QSO and after it was over, I realized that the little Tin had a lot more potential than I had realized. It seemed to me that if my little signal could skip all the way to Colorado in August, then it should go a LOT further during the winter DX season ... perhaps far enough to work all fifty states? It was at that point that I decided to give it a try.
I re-pruned my 40m half-sloper as well as adding 35 buried radials and as the fall DX season approached, I watched 7040 every weekend ... the new states soon began piling up.
To shorten the story, in early December of that winter, I worked WG7Y in Wyoming for state #50 to claim the first-ever Tuna Tin 'Worked All States' ... all on 7040 KHz. Unfortunately the ARRL does not have any special endorsements for Tuna Tins but they did stamp my 'WAS' certificate with a 'QRP' notation!
At some point in the intervening years, the little Tin's final amplifier, the ubiquitous 2N2222, went south. As I removed and examined the tiny old battle-scarred soldier, I remembered so many hours of late-night pleasure it had brought me, along with some memorable sessions ... one being a snowy late Friday night opening to the east coast that put the last three needed New England states into my log in less than thirty-minutes.
I carefully placed the little transistor in a piece of anti-static foam, not that it needed protection, but as a keepsake and a reminder of its noble past. Possibly I would mount it on a nice hardwood base in the future.
Earlier this year I noticed, when cleaning the shack, that the little black keepsake could not be located ... I figured that it must have got sucked-up in the shop-vac during one of my rare shop clean-up days.
I always empty the shop-vac, which consists mostly of fine sawdust or wood shavings, onto my large pile of lawn-mower clippings, which seems to stay about three-feet high no matter how much I keep adding.
Emptying the grass catcher last week, during the final mowing of the season, a small black object sticking out from mid-pile caught my eye. It was indeed my old friend and, after reaching out to 50 states, she still had enough left for one last call to me! I'll take much better care of her now and keep her in a safe place, away from the nasty shop-vac.
I eventually went on to build a 20m Tuna Tin, also crystal-controlled on which, at last check, had brought 46 states and a DXCC total of 21 countries. This inspired a 'mini-tuna', built into a small cat-food tin and using just a barebones 2N2222 crystal oscillator. This one has brought 33 states over the years.
I have more Tuna Tin info, along with circuit information on my main web site here ... but be warned -- 'Tuna Tin fever' can strike anywhere at anytime.
