KWS-1 Power Supply Crating

The Buyer wanted me to crate and ship the Power Supply to Howard, W3HM When I purchased the KWS-1 a year ago – I only sent the RF Deck to Howard, W3HM, to have him completely refurbish it. At 170 pounds – I decided not to send the Power Supply across the country to re-powder coat it. Mainly because the Power Supply would be…

W6LVP Loop – Part 2: Install Outdoors

The W6LVP Loop on a Yaesu G-450A rotator It may look like the antenna is tangled in the branches, but its in the clear – in fact its away from houses and other metal as much as I can do on my “semi-rural” lot. On the other side of that deer fence is a creek – so if moist soil helps a loop –…

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…
