Re: Akihabara, Tokyo

 

My wife and I would love to go on such a trip, however I see that the Tokyo Ham Fair is scheduled for August 23-24 (2025), only one week after our planned return from Iceland. How about another trip in 2026?

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!

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 and Doug,

Prices of Japan-made transceivers are very low thanks to the weak yen (150 yen to 1 dollar). You can get a new IC-705 for under $1000. 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. I didn¡¯t see any China-made HF transceivers, such as Xiegu, however. The situation like this, I don¡¯t believe, will last for long if history is any indication. We have been having great lunch for about $10 per person.

Shall we organize a ham tour of Japan, perhaps in conjunction with a Ham Fair (counterpart of Dayton Hamvention) in late August?

Re: Akihabara, Tokyo

 

Thanks for sharing, Hiroki!? I recently spent a week in Japan with two friends.? Neither were hams, so I didn't get a chance to explore Akihabara like I would have liked, but I was astounded at how much I enjoyed the trip and I really want to go back sometime.

hi, 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

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.

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,

Amateur Radio Emergency Preparedness Act Re-Introduced

?

Legislation Will Increase Communication Options During Natural Disasters

?

WASHINGTON ¨C U.S. Senators Roger Wicker, R-Miss., and Richard Blumenthal, D- Conn., and Representatives August Pfluger, R-Tex., and Joe Courtney, D-Conn. announced their joint re-introduction of legislation in the Senate and House to restore the right to Amateur Radio operators to install the antennas necessary to serve their communities.

?

Homeowner association rules often prevent Amateur Radio operators from installing antennas at their homes even though Amateur Radio has proven to be essential in emergencies and natural disasters such as hurricanes when other means of communication fail.

?

¡°Mississippians should have access to every possible means of warning for natural disasters, including amateur radio operators. In an emergency, those warnings can mean the difference between life and death,¡± Senator Wicker said. ¡°The Amateur Radio Emergency Preparedness Act would remove unnecessary roadblocks that could help keep communities safe during emergencies like tornadoes, hurricanes, and fires.¡±

?

¡°When disaster strikes, amateur radio operators provide vital, often life-saving information, which shouldn¡¯t be hindered by prohibitive rules or confusing approval processes. The Amateur Radio Emergency Preparedness Act eliminates obstacles for ham radio enthusiasts, allowing them to continue their communications and serve their communities in the face of emergencies,¡± said Senator Blumenthal.

?

¡°Natural disasters and other emergency situations that hinder our regular lines of communication are unfortunately unavoidable, which is why we must bolster our emergency preparedness by removing the barriers amateur radio operators often run into when installing antennas. Amateur radio plays a vital role in public safety by delivering critical information to people at all times. My district is home to dozens of amateur radio operators ready to volunteer in the event of an emergency, and I am proud to lead this legislation,¡± said Congressman August Pfluger.

?

¡°As we know from recent natural disasters, amateur radio operators in Connecticut can be a critical component of disaster response and emergency management. It is in our communities¡¯ best interest that we give them the capabilities to operate at the highest level, and with the re-introduction of this bill, we¡¯ve taken a strong step in that direction,¡± said Congressman Courtney.

?

Background:

The Amateur Radio Emergency Preparedness Act of 2025 (H.R. 1094 and S. 459) would require homeowner associations to accommodate the needs of FCC-licensed Amateur Radio operators by prohibiting the enforcement of private land use restrictions that ban, prevent, or require the approval of the installation or use of Amateur Radio station antennas. Homeowner associations have often prevented installation and use of such antennas through private land use restrictions. This has hindered voluntary training for emergency situations and blocked access to necessary communications when disaster strikes.

?

Among other provisions, this legislation would:

  • Prohibit homeowner association rules that would prevent or ban Amateur Radio antennas;
  • Specify an approval process for installing Amateur Radio antennas;
  • Provide a Federal private right of action to Amateur Radio operators in disputed cases.

On behalf of America¡¯s Amateur Radio licensees, Rick Roderick, the President of The American Radio Relay League, re-confirmed the ARRL¡¯s full support for the passage of the Amateur Radio Emergency Preparedness Act of 2025 and extended his thanks and appreciation to Senators Wicker and Blumenthal and Congressmen Pfluger and Courtney for their unflagging leadership of the bi-partisan effort to support and protect the rights of all Amateur Radio Operators.
