The previous gen Alex Loop gets major praise IMO for at least three things: it is simple, quick to set up and take down, and it just WORKS! On 28 June, I tried out the AlexLoop I now own (thanks Joy!) at Baylands. Under marginal band condx (20M) I worked 3 POTA stations without difficulty.

There was a favorable review of it in a recent QST (attached).?

Hiroki,
I plan to be at there. Can you bring one of your 1N4756 Zener diodes. I checked the data sheet, and it has about 30 to 80pf when it is reverse biased. I looked at the bandpass filters on the output, most of the lower bands have capacitor values well above 50pf. It may have some impact on 10M which has an input cap close to 50pf.
Thanks, Dave W6VYC

Re: Zachtec arrived today
Yes you are right.? And they will be down in the mud, but workable if you have patience and are lucky.? Luck is a big part of it.? ?I was able to work 6 of the 13 Colonies Pota stations, but none of them have posted logs yet.? That took some patience and lots of luck.? But the thrill was worth it.? 72, Doug

I can tell you from experience with SOTA/POTA that you will work the East Coast, just not very frequently.? There are some big guns out there, shooting for any SOTA/POTA points they can get their hands on.

Re: Zachtec arrived today
This was for 10 minutes using Chelegance MC-750 with resonance at 14.050 and swr of 1.13:1.? Now I have a good idea of who I can hear on Pota right now.? Probably not going to work the east coast.? Is that the right assumption?? Doug, trying to learn.

It's been on 20m on the inverted L up 27ft.? and the results are astounding to me.? 4103 spots, 13 dxcc entities, and almost every state!!? All on 200mW.? Longest distance? was a VK at 14,900 km. which is about 9258 miles.? ?Amazing.? Yes it works.

Off topic but on topic from lunch last Friday. Union Pacific Big Boy 4014 Over Donner Pass
At lunch last Friday I said I was going to Auburn and we were going to see the Union Pacific Big Boy 4014 make a 15 min stop at Colfax on its way from Roseville to Sparks. The schedule didn't go as planned because the "Big Boy" hit a tree on the track somewhere around Auburn and had to stop, have a repair and then continue onto Sparks. The stop at Colfax was cancelled. Big Boy ?was hours late and the great majority of the crowd, including us, were long gone. Below is a video of "Big Boy" on the tracks at various points from the other day.?
?
Union Pacific's Big Boy 4014 is a BIG BOY. Big Boy weighs in at 600 tons, is 132 feet long, and can move at up to 80 miles per hour while pulling a fully loaded freight train with the force of about 7,000 hp. Union Pacific introduced the first of 25 of these steam locomotives in 1941 and retired them from active service in July 1959. ?Several 4-8-8-4 locomotives later went to museums around the United States for preservation. In 2013, Union Pacific bought back Big Boy 4014 from a museum in Pomona, California, to restore and operate. Big Boy is the world's largest ?steam locomotive.
