Which page are you viewing? Vacuum tube T/R switch
I used a homebrew vacuum tube T/R switch for QSK CW back in the 1960s when I was WA1FMM. Couldn't afford the EF Johnson device, but building one was not hard. I followed a lit of advice by Law McCoy (W1ACP?). Gonsett GSB-100 (100 watts), T/R switch, low-pass filter, Drake 2B. It worked perfectly. "Total Immersion CW," what an experience! 73/KK6CY

Very interesting and attractive page. I got my license a couple of years ago, but since I’m retired and can’t afford sophisticated gear, I am tinkering around and working my way up to homebrewing. Thanks and 73 !

This is a great page for anyone wanting to build a simple tube receiver or transmitter !
Thanks for providing this information !
Great info and since i am a Regen nut , maybe i should try the simple 3v4 ! Couldnt find the updated one with maybe a Audio Xmfr for more Volune ?
Like the other old stuff too, Thanks& GL, 73

hi thanks for great site i built the 6aq5 tx works great thanks joe
I built a home brewed Ameco AC-1 transmitter in a cigar box back in 1956 and worked countless stations on 40 meters (7173 KC)
Sure wish I had it back. I also built an oscillator using a 30 tube around the same time. Still have that one. Good to see the transmitter is still around. 73's Chuck K8BBE

Interesting to see these old designs. Wondering if these old toobers will ever "spark-up" that same interest they did 100 years ago? "Classic stuff here OM"! All the best..
(still make QSO's w/my old Swan-350 at least a few times ea yr)

Which page are you viewing? 6L6 trans and power supply
Looking to do some building projects with older tubes.
Which page are you viewing? 6L6 XMTR
Watching a show abt wartime Europe, and how the Nazis collected personal radios from the populous. Someone said, "Why did they do that ?"
In return I explained how receivers had the parts in them to be used as a transmitter... Using the power tube (a 6L6 for example), the power supply and an improvised code key, and here you have it all drawn up!
Thanks for the support of my knowledge. Young people familiar w/
iPhones and computers, HAVE NO IDEA !
All the Best from FN51so !

Which page are you viewing? hartley tube transmitter
I remember back in 1951, I build this in the shop in school. Those days will always be remembered. It was so cool building electronic projects on a nice wooden board. It just seemed like a personal thing for me. I also built a 2 tube receiver which worked rather well on 40 m. That was when parts were so easily available and get most of it at surplus stores. Over the many years I have been a ham, I built a lot of stuff, mobile and fixed. I remember when Heathkit was a dream for me and built many kits. It's too bad that kits are not offered any more unless you do home brew.

MATCHBOX NOT TUNER. NO SUCH THING AS AN ANTENNA TUNER.
YOU MAY ONLY TUNE BY PHYSICAL ADJUSTMENT OF THE ANTENNA ITSELF.

Greetings. CW QRP XMTR looks like fun. I might just build it.
Which page are you viewing? 6DQ6 transmitter
Wow, your 6DQ6 transmitter looks beautiful. All of my transmitters have been built with 6L6 tubes except for one "spy" set using a 1G4 tube with one watt output. I built a complete 80 meter station into four French wine boxes that when packed up would look totally innocent in the back of a horse drawn cart as it was being pulled past a Wehrmacht checkpoint in northern France in 1944 : ) I donated this set to the Antique Wireless Association when I moved to Florida in 2014. I am finally back on the air as of 1/1/2017. Looking forward to building with tubes again and was checking out your excellent projects. 73s, Randy KB2PLW
