Thanks for passing this along. I'm glad to hear that. Woohoo!
Given the cost of designing and producing new radios I have to think they'll borrow heavily from an existing production unit, most likely the Eagle?
Good to see that Ten Tec hasn't given up on the QRP legacy.

Reminds me of a modern Scout...IIRC, that was the first ham radio I had a chance to use Smiley

Pretty cool, although the siren call of the KX3 is still strong.

I was looking for an Icom IC-703, but I might just wait for this new Ten-Tec instead.

 The Ten-Tec 539 should be a good QRP radio if based on the Eagle,it all depending on its price-point. I wood want AM broadcast bands from 0.5 to 1.6 added ,because when in the outback I do want to know what's going on around me.

It would be nice if it had a built-in antenna tuner, like the IC-703 or (optional) Elecrafts.

 I agree it wood be nice, but they must keep a low price point on the 539 to keep sale up,and at the same time give we the customers what we want? I would like them to drop the 160 meter band on this QRP rig ,and add the BCB band 0.5 to 1,6, also bat pack is need as well as the tuner you want ,maybe the after market will help?
note: do you think the 6 meter band is needed on this rig, have your say?

I agree with N5RWJ about dropping 160 meters and adding 6 meters!

Agree on drop 160m, add 6m. I have a 703 (not Plus) and while 160m is nice to be selectable, with QRP, a full size 160m dipole would be a LOT of wire to carrying around in a backpack!
I use a 746Pro at home on 160 with a mobile-type antenna, and with 100W and an inefficient antenna, contacts are possible. With 10W or less, a full size antenna would be a must...

I wonder if it will have the same lousy TX IMD performance like the Eagle, which is almost class C.

These QRP radios generally seem to be poor in every way, poor RX and poor TX. I mean I would like to buy one that I can use say with a grid driven tetrode driving   a small 4cx350FJ with say 1 watt or less. The problem is that most QRP radios have such poor  IMD and harmonic suppression specifications that doing so just causes misery on the bands.

Companies like TenTec just dont get it when it comes to issues like TX IMD. All I expect from Ten Tec is another radio with CB like TX IMD performance. Their past product track record tells me that this new radio will be no different.

I have A German Telefunken  HF manpack radio designed in the 80's This radio at 20 watts has 3rd order IMD figures of -36 db below PEP. and this is on battery power! Name one ham radio transceiver has such excellent IMD figures even at 20 watts, good luck!

Anyway more concept junk, with no real improvement in either TX or RX performance. I suppose its just  there to head of competition from the Elecraft KX3.

The same comments apply to their new MOSFET amplifier. Probably cheap  MOSFETS pushed to the limit. Typically people who these kinds of amps use radios like the FT817 which has marginal IMD to begin with. The end result is many more people messing up the bands with splatter. Its time that the FCC required  minimum levels of IMD performance for type acceptance.
