Re: Akihabara, Tokyo
I visited Akihabara during the mid-'90s during a business trip. Thankfully a colleague from my company's Tokyo office served as my guide. It was a wonderful experience--there were all kinds of shops with very cool stuff. It seemed as though all the '50s-'60s U.S. tube audio gear ended up there (I would later find more such gear in Seoul S. Korea).
?
One shop offered an array of beautiful connectors and cable, especially for audio-HiFi-stereo apps. I bought about two dozen connectors and some cable, and upon my return made up some cables for my stereo system.
?
From my notes, there is an article on Akihabara in the July 2002 issue of IEEE Spectrum magazine.?

Fw: [SBMS] KD7DTS plans to operate 10.3681GHz on Mt. Lawlor soon today using 447MHz W6TRW Repeater for liaison SOTA operation
The video shows a typical microwave operation. One minor technical error relates to polarization. They are using horizontal polarization, not vertical. In rectangular waveguides, the E field goes parallel to the short side.? The long side needs to be at least 1/2 wavelength.?? In the US, most hams use horizontal polarization.?? In Japan, vertical polarization is the norm.? So the 10G module for the IC-905 needs to be mounted differently from the factory drawing. Locally, favorite spots to operate include Mt. Diablo, Mt. Vaca, Loma Prieta and Mt. Umunhum.? None of these are easy hikes! ----- Forwarded Message ----- From: Michael Aust via groups.io <ava622@...> To: "[email protected]" <[email protected]> Sent: Thursday, February 13, 2025 at 01:49:06 PM PST Subject: Re: [SBMS] KD7DTS plans to operate 10.3681GHz on Mt.

Re: Akihabara, Tokyo
Count me in, Hiroki.? I marked my calendar for the Ham Fair and want your recommendations for air, room and sights.? I would like to take the fast train to Hiroshima. Bob KF6ABC

Bob and Doug, I only bought two small tools (a very sturdy fine-pointed tweezer and a cutter to clean up after see the thru-hole soldering) and a small project box.?

It is a good time for Americans to go to Japan to buy some ham stuff. On the other hand, China-made accessories and components are more expensive in Japan than in the US.

Re: Akihabara, Tokyo
¿ªÔÆÌåÓýhi, big warning about buying a JA model xcvr for a low price.? it may not allow all features as we use in US.? And it may not be reconfigurable - no MARS mod.? this is a pretty common question on the various xcvr email groups I subscribe to.? "Hey, I got a great deal on this IJK-321 box, but it doesn't do all of 2m band" or whatever.? for many modern units, the answer appears to be no, it's not fixable, you're stuck! JA models are different, EU models are similar, US models are again different.? common differences are frequency coverage (only 146-148MHz, no 144-146; 70cm only 430-440, not 430 to 448, or even better 42x-448; missing or wrong 60m channels), features (no NFM, or NFM only no WFM), max power output (10w for JA entry license?). so, double check.? and then check again.? my $0.03, inflationary $0.02 Cliff K6CLS On 2025-02-13 00:51, Hiroki Kato wrote:

Re: Looking to Ditch X? Morse Code Is Back
Hiroki,? good article.? ?I know 5 of the people who were quoted in the article.? I find it interesting how the members of our group value cw, especially when? they realize how much better it is than voice when trying to communicate in marginal conditions.? It is also interesting to see how much POTA and SOTA have popularized the use of Morse Code.
?
I have a question for the group.? How fast can you copy Morse?? I can copy 20 wpm and with regular practice and a good operator, 25.? Please answer even if you don't copy at all.

My boat arrived in Tokyo this afternoon and I beelined to the Akihabara electronics district, my old favorite haunts while my wife is nursing her cold on the boat. To my delight, many small stores catering to DIY enthusiasts have returned with force. You can literally find anything if you look (but you do need to look around). The photos below show only small samples of those shops. One store sells nothing but enclosures in different shapes and sizes for any kind of applications. This store specializes in inductors. Not only can you find any size of toroids and ferrite cores but you can find ready made wound toroids of any value, perfect for lazy home brewers. Hope everyone is doing well and enjoying Friday get together in field or online. East Asia now is unusually cold. Hiroki AH6CY |

Re: Akihabara, Tokyo
These are fantastic pictures, Hiroki! ? I visited Akihabara a couple of decades ago, and I was blown away back then. I wasn't so much into radio at the time with a couple of small kids but all the electronics and the way it looked at night was all stunning. It may be time to start thinking about a trip back to Japan! ? (not just for Akihabara) enjoy your trip, ES 73, Connie W6EFI On Wed, Feb 12, 2025 at 02:50, Hiroki Kato <hiroki@...> wrote:
