SW-3, Brave New World and KWS-1, Brave New World Revisited

The SW-3 and Brave New World were Created in 1931 . . .  and . . .   The KWS-1 and Brave New World Revisited were created in 1958 . . .  Its just a coincidence – that the two radios are of the same era as Huxley’s famous book and his musings on that book almost 20 years later. Brave New World Revisited…

First Gold Dust Twins QSO!

My first QSO with the Gold Dust Twins was with Wayne, N7NG FINALLY – it was so ironic today – skip was longer than expected, and the RBN reverse beacon stations heard me – as far away as Uruguay, and very strong into the PNW, but I couldn’t get an answer. Luckily, my DX buddy Wayne, N7NG responded to a pleas I made on…

Gold Dust Twins: First QSO This Weekend?

The Gold Dust Twins I will get my twins on the air this weekend – on Monday I found the issue with the KWS-1 and will get it fixed and on the air this weekend. Even before I fix the problem I know what I can do to get it on the 40M SSB band – which is where I will try it out…

Monitoring the KWS-1

MFJ-267 Dummy Load / Wattmeter and Palstar PM-2000A Wattmeter The MFJ-267 (upper left) with my mod to add two micro muffin fans has been a really great piece of gear for my KWS-1 “adventure”. It stays cool when I tune the rig up – even when reaching 700 or 800 watts. I purchased a Drake W4 Wattmeter, but it arrived damaged – so I…

KWS-1 (and much other) Progress

I was able to get the KWS-1 to tune up at one high frequency on each band – and I measured 300 watts out on 75M. I also used the microphone to key the transmitter in SSB mode – but besides a key down carrier, I didn’t hear the mic voice. I’ll worry about that later – it could just be the way I…

Hello Grid Current in Tune Mode!

Just for fun, when I got home from work – I decided to tune the KWS-1 all over the crazy place, and sure enough – I did find what looks like “resonance points” where I could get Grid Current to display from zero to full scale on the Grid setting of the meter in Tune mode – and this is the “tune for maximum…

My KWS-1 and the Strategic Air Command SSB Tests

The Strategic Air Command, Gold Dust Twins and SSB in the 1950’s – Cold War Style . . . I purchased my KWS-1 from an antique radio shop in Sacramento called Radio Expo: http://www.sacramentoradioexpo.com/ The owner, Doug is a real nice guy, and even taught at Stanford for a while. He came across this transmitter just under a year ago when a ham who…

KWS-1 Report

I put about 6 hours into testing the KWS-1 yesterday and another 2 today I’ll record the important metrics here – because I can then compare these to others who have the KWS-1: VFO INJ Test point – 600 mv Peak to Peak and 3.25 mhz with the dial tuned to 3.5 mhz XTAL – on 40M – 4 mhz, which matches what Howard…

The KWS-1 Has Landed!

I now have RF Output! I am very, very pleased now that I am seeing RF output on my dummy load. The tuning procedure is something I need to get used to, but it is similar to tuning a tube linear amplifier manually. I need to analyze why I don’t see Grid Current on the built in meter and why I don’t see anything…

KWS-1 Debug: Day 1

L – R: Siglent 1202X-E, KWS-1 with MFJ-267, Fluke 117, Hickok 533A. Not shown – Heathkit IG-102 Signal Generator Nothing better on a gorgeous Spring day – (after an especially intense work week) to have some nice coffee and then to get crackin’ on getting the Collins KWS-1 transmitter back on the air. I’ll do it – damn it!   The simple, but effective…
