Feynman’s Red Book (on the Sino-Indian Frontier)


Today I bought a copy of “Feynman’s Tips on Physics.” I wasn’t sure about buying it, but this story in Ralph Leighton’s foreword convinced me:

“At a lonely border post high on the Himalayan frontier, Ramaswamy Balasubramanian peered through his binoculars at the People’s Liberation Army soldiers stationed in Tibet ― who were peering through their scopes back at him. Tensions between India and China had been high for several years since 1962, when the two countries traded shots across their disputed border. The PLA soldiers, knowing they were being watched, taunted Balasubramanian and his fellow Indian soldiers by shaking, defiantly, high in the air their pocket-sized, bright-red copies of Quotations from Chairman Mao ― better known in the West as “Mao’s Little Red Book.”

Balasubramanian, then a conscript studying physics in his spare time, soon grew tired of these taunts. So one day, he came to his observation post prepared with a suitable rejoinder. As soon as the PLA soldiers started waving Mao’s Little Red Book in the air again, he and two fellow Indian soldiers picked up and held aloft the three, big, bright-red volumes of The Feynman Lectures on Physics.

One day I received a letter from Mr. Balasubramanian. His was among the hundreds I have received through the years describing the lasting impact Richard Feynman has had on people’s lives. After describing the “red-books” incident on the Sino-Indian Frontier, he wrote, ‘Now, twenty years later, whose red books are still being read?’ ”

Arduino Adventures: LCD screen added

Pretty impressive for a guy whose previous project was a crystal controlled DSB transceiver, don’t you think? They say that variety is the spice of life, and the Arduino board has been adding quite a bit of spice to my tech life lately. That tiny board up above the proto board is the six dollar DDS-9850 board — it arrived in an envelope from Shenzhen, China last week. I hope to connect it to the Arduino and the LCD to make a sig generator or VFO.

How many hams in China? Not many.

I’ve been wondering about amateur radio in mainland China. Given the very large population, and the high levels of technical and engineering activity, you’d expect to see evidence of more ham radio activity from that country. Sure, there are plenty of commercial rigs manufactured there, but I’ve never seen an article about a Chinese homebrew rig, or a reprint from a Chinese ham radio magazine. I did some Googling, and unfortunately found out that my suspicions are correct: There are very few Chinese radio amateurs.

What a pity! Imagine the great rigs and circuits that would come out of that country.


Here are the numbers from from a 2009 IARU report (authored by the Chinese Radio Sports Association:
The total number of individual amateur radio stations in the mainland of China is about 19,000, while the number of active club stations is 124as counted in March 2009. In fact there are over 10,000 new comers get amateur radio station licenses each year, the total number of certified amateur operators during the past 10 years is accumulated as over 70,000. However, as the license is valid for 2 years and about the same number of previous licensees did not renew their license in time in each year, the net population of valid transmitting amateur radio station appears almost flat.

Alaska QRSS Grabber Controlled from CHINA!

Our friend Laurence leads an interesting life…

Hi Bill and greetings from the NE coast of still summery China – actually its cooling down a bit from boiling over to just cooking.

Just been home to Alaska. Whilst and between lumberjacking 20 dead trees on the property I had a few mins to throw up a K9AY and connected it via 250ft of Walmarts best RG6U into the R75 – with a little help of Ham radio delux, Citrix and Skype I have control of the radio from here in China – Mostly on 30m but really shoved it up for the winter lf/mf season but of course WSPR and visual modes have proved very popular. So until a moose walks thru, a Wolf chews threw or wife cuts thru the antennae wire it will be up.

Here in China I’m sporting the second r75 and this supplements the SDR IQ – my antennae are gradually getting blocked towards the states and Eu by every rising high rises just in front and I can actually measure the increasing losses at LF and HF as the beast rise. Still looking for your WSPR signal and keep up the good work.
