Welcome to VU2YK

An avid experimenter and Home Brewer since I was 14. Got my licence at 18 and have been on air ever since. First Rig was a single tube EC81 Transmitter and a modified broadcast RX. Must have been a couple of watts out into a low hung dipole.Thefirst contact was with VU2XA about 400 miles away on a lazy summer afternoon who gave me a 477!! ( By far the best report I ever got !) Prior to that I had never ever seen a TX in operation. I did not believe I had made a contact till I got a QSL from the guy in my mailbox. That's one card I would always like to keep. That day I felt like what Marconi must have when he made his first contact. That was real radio. I was a class 10 student in High School. Remember The year was 1968, there was no internet and my only source of circuit information was a few local magazine clippings.

Then came several CW/AM transmitters which had 12AU7/EF91/6CL6/pair 807s in lineup. Followed in 1971 by a filter SSB rig using locally made BEL filter.Then came along a HW101 putting end to my home brewing for quite some time. I might have the dubious distinction of putting together the whole of HW101 kit in one night. I guess I still need lessons in patience!

Then followed a roaring affair with an FT 101ZD and a home brew linear built around quad 811As, which were eventually substituted with 572Bs. The 101ZD is one of finest radios ever to be built and I got some excellent audio report with the speech compressor. I still believe that was one of best RF speech processor ever built into a rig.


Rigs used in the past
















Furuno Marine Amp. Modified for Ham use, 300 Watts out

Dentron MLA-2500B used sparingly.

Antenna is a Two Element Boomless Cubical Quad based on famous design by HB9PL. Completely home made including a tilt over tower. About 21 Meters (63 Feet) from Ground.

Current Shack. Despite owning some modern radios, I still use the venerable TS-530S most of time. Even if it takes time to warm up, drifts noticeably and needs to be retuned every twenty KHz, still the best radio in its class.

Motor Cycling

When I was in college I was gifted a 1971 JAWA 250 CC Single Cylinder Two Stroke Bike by my dad. It was made in India with Czechoslovakian collaboration. Motorcycling fever returned when I turned Sixty. Now ride this beautiful Royal Enfield Classic 500 CC machine.


I picked up this mint TS530S from a ham in the US. It was working flawlessly till hit by some strong RF field and lost its antenna input coil L41. It was with help of Yahoo groups and specially Terry Wagoneer, K9TW and some local friends VU2ASB and VU2PPP, I rewound the delicate coil and restored back its receive. With the Shure 444 microphone it produces audio which is unmached even by current rigs like the TS590SG and IC-7300 ! Even after forty five years the radio performs real well.


A previous shack with IC-7000 and Behringer Audio Chain. It was quickly replaced by TS-480HX.



Addressing the newly formed Delhi Amateur Radio Technical Society. Egging hams to come out of their shells and come on the air.


My other interests are Motorcycling and Animal Welfare. I work for the welfare of street animals in my hometown New Delhi.
