Description: The Two Tinned Tunas ( TTT) kit is an updated version of the classic TT2 kit designed by W1FB, Doug Demaw. The TT2 transmitter has been kitted by several QRP clubs in the past. This kit comes COMPLETE with all PCB mounted parts: transistors, capacitors, resistors, toroids, magnet wire, crystal, crystal socket and key jack. All chassis mounted parts: RCA jacks, T/R switch and PCB mounting hardware are also included. All the parts come sealed inside a factory fresh tuna can with an easy open pull top lid. This kit is suitable for 'beginners' or 'experts' alike and can be assembled in one evening.

A nice kit   Time owned: 0 to 3 months
I am reviewing the newer "E-Z build board" currently available from QRPme. This has "cool" written all over it. You get a round tuna type can with the board under the plastic top lid and the parts inside, after you crack the seal. All the parts were there. The board has larger solder pads and is not at all crowded so I'd say if you were just getting your feet wet to kit building this would be a good one. I took my time, did not hurry and it probably took 3-4 hrs to put it together.

There are some instructions available on the internet which show large color pictures. One warning if you're new to kits: the most accurate source of information is the schematic, use it. The instructions are at times (e.g. when illustrating installation of R9 and R10) incorrect, but if you check against the schematic as you go along you'll be fine.

I'm a caveman but my radio worked correctly the first time: a testament more to the design and nicely laid out board. One tip: the variable resistor that sets PO was set wide open on mine (fully clockwise) and a couple of seconds key down had the litte 2222A cooking. Well duh! I set it fully counterclockwise and gradually increased it, using an uncalibrated finger as the test instrument. I'm now putting out about 350 mW, which is typical of this design and the final is only very slighty warm. The note sounds good. I plan to use this with my Ten Tec DC receiver and see what she'll do.

FUN  Time owned: more than 12 months
this kit has FUN written every part on it!

The only disappointment was when I finished the kit. I missed having fun!

This kit works as advertised.
Intructions are better than heathkit's!

Instructions are actual photos with parts shown where they go

I still haven't made QSO's wit it. My CW isnt up-to-date.

Fun to build, fun to use!  Time owned: 0 to 3 months
What can you say that hasn't already been said about the late Doug DeMaw's classic "Tuna Tin 2" QRP transmitter?

Well, has gone this favorite one better, by adding a third transistor and packing a complete kit of parts in a factory-sealed tuna can, complete with whimsical label!

From the time you yank the pull-tab to get to the parts, this kit says, "fun"! It's an easy, one-evening build, and construction is simple enough for a beginner and satisfying enough for an old hand.

The instructions (in PDF and Word form on a mini-CDROM) are the clearest I've ever seen in 40-some years of kit building. You would have to really work at messing this one up! The hardest part is winding the toroids, and they're not hard at all.

The TT2 has an ideal companion in the "Sudden Storm" receiver, another QRPme tuna tin success, but you can use the transmitter with any 40 meter receiver. And, because you connect your receiver to a jack on the side of the TT2 xmtr and select transmit and receive via a "front panel" switch, on-air operation is a breeze.

Remember, this is a QRP rig--it puts out less than a watt--so you're not going to be cracking pile-ups, but it is incredibly satisfying to actually make cross-country QSOs with milliwatts! My first QSO was from Louisiana to Virginia, my second to Alabama; not bad for a transmitter putting out less power than a flashlight!

Keying is remarkably clean and chirp free (thanks to that third transistor) and there's been no sign of drift. The kit comes with a 7040 kHz QRP calling frequency crystal, but it is socketed if you decide to try another part of the band.

The "Two Tinned Tunas", like the other incarnations of the TT2 transmitter, has +12VDC on the shield side of the key jack, so there's a good chance you won't be able to use your keyer, but it really "feels like ham radio" to be able to plug in the ol' straight key and hammer out some contacts. If you want to use a keyer, there are simple mods floating around the 'net, or you can concoct something of your own.

QRPme's TT2 kit is a good performer, a nice value, and especially because of its clever packaging, makes a fun gift for the hard-to-shop-for ham on your list.
