[HamBrewers] servo control of Pi Tank / Ant Tuner / VFO
I came across this novel idea of using Remote Control Toy Servo motor to drive variable capacitor/ inductor in Amplifier and tuner projects.
These motors are available on ebay india as well.

Well said Pramod.
Please note that most of the parts stockists on SP road were Sindhis who came to India from Pakisthan as refugees. The Marwaris if any invaded later!
So what, why should we feel distressed with the reality. Just the other day, I heard some one celebrating Jagadish Chandra Bose’s birthday on 40 meters, convincing others that JC bose was the real inventor of Radio and Marconi was a cheat.. and so on. What I mean to say is, a good number of hams have no problems what so ever, living in the Graham bell era..
And also not to be confused with another gentleman who may claim to have founded ARRL and is a direct descendant of Hiram Percy Maxim Bose. He may also claim to have invented those speakers and founded the mens magazine.. There may be some resemblance I might add. From Wikipedia:
7. HAM Radio
An estimated six million people are still involved with this hobby that began at the start of the 20th century. HAM radio operators communicate with each other over short wave radio. HAM radios have been featured in many popular movies, including The Shining and Contact.
8. Reel to Reel

Re: [HamBrewers] Vintage Technologies We No Longer Use
Hi Raj,
Just the right material I need today
I am going to do a ham radio demo/presentation @ IIT Madras this evening and plan to show email as an ice breaker along with a couple of ham radio related videos.
Starting with the below presentation to explain "What is Ham radio?" which I used in the Hamradio workshop for Chennai Trekkers club members in Dec 09. http://chennai-trekking-club.32436.n3.nabble.com/Ham-Radio-workshop-Tue-22-Dec-8-10pm-tp92485p92485.html
After which I plan talk briefly on the below topics using slides available in the link below.
Disaster management - Emergency communication using slides from
http://www.emergencyradio.ca/course/ARESWinlink.ppt and
http://www.emergencyradio.ca/course/Last%20Mile.ppt
Introduction to Microwave Amateur Radio using
http://www.larc.ca/meet-2008-04-10-Microwave-Ham.ppt
Introduction to Amateur radio satellites using
http://www.amsat.org/amsat-new/information/faqs/Intro_sats.pdf
Software Defined Radio (SDR) using the presentation at http://openhpsdr.org/kk7p/lyle-dayton.pdf after updating contents to reflect current state of the project
Contesting using the presentation at http://www.k1ttt.net/misc/hcra_intro_to_contesting.ppt
And finally about World Radiosport Team Champianship (WRTC) using presentation at
http://www.k5zd.com/articles/wrtc2010/K5ZD_WRTC2010_Presentation_27Aug10.ppt
Any quick tips/points to cover are most welcome

Everyone is entitled to have their opinions. Having said that, the reality of the present day,technological world seems to hit us hams badly.
We love CW, HF SSB, EME, SSTV, FOX Hunt,QRPP DX and OSCAR and the list goes on, these were all considered break through technology / Space age stuff in the last century.
Whether we practice all these with an EL84 vacuum tube or with the powerful FPGA/DSP/SDR based equipment, these aspects are not of great interest to the communications industry and the scientific community at present from a novelty point of view.
A good measure of hams are finding it increasingly interesting and easy to use Echolink kind of internet communication applications, whether echolink is really hamradio is the moot question here.
If we do not get into the merits of it, the apparent benefits are are,
no need to buy expensive and dedicated radio hardware
can operate from anywhere in the world without the headaches of obtaining reciprocal licenses.
XYL does not object to the echolink PC/Laptop sitting in the bedroom
Can co-exist with email, eQSL ….
Completely independent of propagation vagaries and zero QRM most of the time.
No TVI and telephone interference
No monitoring by wpc… and no Pink letters.!
Irrespective of our infatuation with the hobby, if we see the outside worlds' point of view on our beloved hamradio, ( ignoring the increasing dependency on it as a disaster communication backup) it appears pretty well justified being bunched with floppy disks and VHS tapes.
So what, why should we feel distressed with the reality. Just the other day, I heard some one celebrating Jagadish Chandra Bose's birthday on
40 meters, convincing others that JC bose was the real inventor of Radio and Marconi was a cheat.. and so on. What I mean to say is, a good number of hams have no problems what so ever, living in the Graham bell era..
When most of our country men had to stand in year long ques to get the ITI made black Bakelite Landline phones and connections, we hams carrying the coveted 2M handys might have made us feel like James Bond. Try the same today, the chances are that most people will mistake you for a courier deliver man, a cab driver or a security agency employee.
Most Marwari shopkeepers in SP road in Bangalore are no longer selling the radio parts. Same is the case in chandini chowk, Lamington road in Delhi and Bombay.
Our own kids and other kids in the street know IPhone, GPRS, WiFi, GPS, HDTV and 4G Broadband much better than an average ham. Even Pakistani terrorists are using VOIP enabled Blackberry/ Smartphones.
Sorry for the really long rant, the bottom line is no matter where the technological world is heading, most of us still love the hobby the way we did
it when we first came in contact with it, even though the rest of the world has moved on. The ham spirit and ingenuity has certainly made a big difference in my professional career. Long live hamradio and hams..

Amature radio is not a "Vintage Technology"... Hi . Probabbly the equipment shown in the picture is a vintage stuff.
Recently heard that LP Records (Vinyl) are on a revival path now. At least there growing number of enthusiasists and collectors in this area

The truth is hard to digest - We still need some make belief to boost our ego and keep the vintage hobby afloat. 73,s Paddy vu2pep --- On Thu, 8/4/11, Birthur, Pramod <pramod.birthur@honeywell.com> wrote:
