Rex, Interesting. Your TT2-EZ has a 2N3866 final transistor where the current design of the Two Tinned Tuna -EZ build uses a 2n2222a for the final. Is that a change? would a heat sinked 2n3866 give

Gangue, I just hosed up my early TT2-EZ Build transmitter to my fairly accurate PM-1300a dummy load/power meter. Powered from my portable Jackery, the input voltage to the TT2 was 13.4 volts. The key

I replaced the LED and the LED works now when I key.? ?I noticed the trimmer resistor was not soldered well, so i soldered it better. C8 and L3 is ok to flow together when you see it on the

Daniel--? Also, if your LED isn't working, you can probably check it with the diode check on your meter with no power applied. Should see something like 1.5V-2.0V drop. Since you are able to key the

Daniel-- Overall, it looks like you did a terrific job!? I should show you some photos of the abominations I built when I first got started. Uggh. I shudder thinking about them now!? Yours is

Hello, I was wondering if I can get some insight into why my Two Tinned Tunas EZBuild is not transmitting. I can hear the TTT on my receiver on 7.110 when I key down, but that is probably the crystal

Please ignore. No part is missing. Brain fart in the morning. My last cap was a 22uF electrolytic cap. My apologies.

I am missing a 22pF capacitor in my TTT EZB kit. Can I use 2 count of 10pF ceramic capacitors instead?? These either came from Jameco or Radio Shack. I used my multimeter against a 1000pF capacitor

The power falls off as the frequency increases, and similarly the power increases as the frequency reduces. Expect about 300mW output on 30m and around 250mW on 20m. On 80m, you'd probably get

Dan, I would also be interested in knowing how this varies per band also, assuming that 40M is the default for all of them Davey - KU9L On Fri, Feb 10, 2023 at 2:47 PM, Colin Evans

OK Daniel, I've had my 40m tuna tin transmitters out on the bench. All of my 40m transmitters put out in the region of 400mW from a 12.6v regulated supply capable of 3 amps. My 12v supply is

Daniel, For my TTT-EZBuild, I got readings of 264 vmax and 179 vrms. The setup was a 12v Gel cell battery in, a Heathkit cantenna 50 ohm dummy load with a direct line from that to the oscilloscope on

Yes, I'll be able to get my TTT out to test at some point. No, the Manhattan project in the picture is a NorCal Forty-9er (N6KR of Elecraft fame). My TTT's are standard can variety :-) 73, Colin

Mine outputs 1.5kW. OK, it's 1.5kW divided by a bunch.? On every TT2 I've built, It's been ~250mW or so. Maybe as much as 350mW.? My measuring method isn't too exact.? I've used both my homebrew

Colin, Can you get out your TTT EZB and test it?? I want to have numbers I can compare against.? ?I just want to be in the same ball park when it comes to power output.? ? If you have screen

I can't remember off the top of my head but somewhere around 400mW would be reasonable on 40m. The FreeKey is awesome! In all honesty, the FreeKey is my favourite portable straight key. The FreeKey

I got my Two Tinned Tunas Kit in the mail the other day from QRPme.com and plan on building the kit this weekend. I even got a free gift.? A FreeKey.? I am not sure if that is included with every

Rex will be selling a nice kit which includes a transceiver with built-in coupler, key, and antenna.? Yep, all 3. The transceiver is an updated Sea Sprite. Did I get this correct Rex? Clicking the

If we could get an estimated date and time to be watching for new rig signals, I would love to give some new comer a South Dakota qso. With qsl card to follow. De n5vwn

Hello, Did anyone notice in an earlier message from Rex Harper, W1REX. This looks exciting: [Rex] will be hosting another Saturday Buildathon live streamed for the March QSO Today Virtual Ham
