Akihabara, Tokyo 10
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

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.

ARRL Member Bulletin for February 8, 2025
If this legislation passes finally, I would be able to put up a decent antenna at my home QTH. There may be others in our group who would benefit likewise. Hiroki AH6CY ARRL Member Bulletin for February 8, 2025 L February 8, 2025 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.

Girl Scout Cookies @ Baylands :)
Dear all, My daughter asked me to share the message below with all my QRPops friends :) Thank you, Gabriel AJ6X Hello everyone! My name is Sophie and I am 10 years old. I have been a member of Girl Scout troop 60943 for five years. The Girl Scout Cookie drive is one of my favorite times of the year because it gives me the chance to sell delicious cookies to everyone I know. I learn how to run my very first business, manage money, talk to people, be responsible and have fun! Hope you buy 100 boxes! My troop plans to do 3 things with the money we earn selling cookies: save for the future, donate to a good cause, and spend on activities. Thank you! Please order here for prompt delivery at the Baylands:https://digitalcookie.girlscouts.org/scout/sophie427046

While Zooming today, I mentioned an OM who built a wooden Morse bug. He is in fact Gary Johnson, NA6O, of Livermore CA. You can find an article on his bug at the site below. Very impressive IMO, wonderful marriage of art and engineering. The article also shows a pic of his Morse straight key. You can find other info from / about Gary on his QRZ page and elsewhere online.
