    I'm playing with the Elecraft T1 today. I love this tuner! Its a Must for your go-bag.

    No tuner is a must for my go bag. A resonant antenna and a couple of mags of ammo is.

    Using a tuner is fine if your into it but not something you should learn to rely on.

    For the price of that tuner you can buy the multi band PAR endfedz , and a jackite pole to run them up. And still have money left over. That thing is pretty costly.

    Geeze, you guys kill me. Yeah, OK, resonant antennas are the way to go for a QRP rig. But hey, this is the real world. A lot of folks (like me) operate across wide swaths of frequencies and don't have the time or space to hang a 100' folded dipole while working POTA activations, to get that magic 'wide-band resonance'. Tuners like the T1 actually allow us to enjoy operating our radios without having to worry about not damaging our rigs.

    I'm just waiting for Elecraft to release their IC-705 interface cable for the T1.

    I have a T1 and its a very good tuner...However!

    I rarely use it as I use resonant antennas and reserve it for difficult cases.
    FYI the PAR EF 40/20/10 has been a goto antenna for over 15 years.

    When power out is low [QRP] adding a tuner is just adding some
    amount of loss you really don't need.

    the one thing the T1 will do is allow you to match your radios 50 ohm
    output to most anything however poor the radiator may actually be.

    I am having pretty good luck with my Antennas4Less SignaLoop HF-319 loop. It's not too expensive, only has one loop so there is less to carry and set up than the double loop ones or the outer/inner loop ones, covers 80 to 15 meters, comes apart small enough to fit in a laptop computer bag, sits on a simple (read cheap) camera tripod, and can be out of the bag assembled and on the air in about 2 or 3 minutes. The bar SWR graph on the IC-705 reads well enough and fast enough to make tuning the loop easy. No cross needle SWR/PWR meter needed. A 6' pigtail from the rig (BNC) to the loop tuner box (PL-259) and it's hooked up. With the loop next to the desk in my shack -- ground level -- inside the house under BIG trees -- and the 705 at 5 or 6 watts on FT8 I'm working everything in the east half of North America from north central Florida easily on 40 - 30 - 20. Even checked into a few SSB nets on 75 and 40! I also have and frequently use hamstick dipoles, a balun end fed wire with a tuner, and a fancy (read expensive) loop. About the same performance but a LOT less set up than hamsticks and WAY easier to change bands. Little less performance but easier/much quicker to set up than the wire. MUCH quicker to set up than the fancy loop.

    There's nothing wrong with using tuners on any antenna. Resonant antennas do not generally radiate "better" than non resonant antennas.

    One suggestion though for the OP. It might be a little more effective checking if the frequency is in use if you tune the antenna system first!

    Asking if the frequency is in use (prior to tuning) while transmitting into an infinite VSWR might not be much better than asking if it's in use connected to a dummy load!

    And as far as low power goes, this video confirms that life is WAY too short for QRP!!

    Cheers,

    Rick

    Elecraft KX2 with built in battery (enables full 10w output), mic and ATU for HF, attach paddles for CW if you wish...

    Smaller, lighter go bag.

    Done.

    Got the IC-705 (which I love!) and the LDG Z-100 tuner which is lite weight and durable for the field. Lots of fun!

    I am 100% QRP at this point working SSB mainly. I operated just as wide an area as anyone else. I looked long and hard at that tuner. With my par endfed the tri-band I can work the three bands it is setup for stock, or I can take the stock wire off, and hook up any halfwave wire and work anything from 60-10. It is not even close to 100ft long. It sets up in no time at all. I dont ever worry about damaging my radio. I find the price point for that tuner to be to high when I can do same work for way less. (My par cost $90) I am not trying to take your tuner away. Use what you enjoy...
