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 :)

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.

The rig is still in development, and if you read the interview that K4SWL did, you'll see that 160 hasn't been ruled out yet. 

Let's wait and see what the final production run looks like before writing the radio off, shall we?

I think it depends on the radio and its price point, we know the front end is coming from the Ten-Tec Eagle and the price needs to be lower than the Elcraft orp rig.

Was told by an employee at TenTec that the price will be just under $1000.

It used to be that somewhere around $500-600 was the sweet spot.  Now it is a grand.  Remember when you could buy a new car for $2000?  At Dayton, Elecraft showed off the kx3 and said the price would be around $800.  I guess they found enough buyers at $1000 to sell it at that price point.  If the new qrp offering from TenTec is up to their usual quality and performance they will sell many regardless of whether the price is $800 or $1000.  Those that whine about the price will need to wait until a Chinese knockoff comes out (which won't be long) at half the price.

Its here already...kind of...the Youkits TJ4A 4 band Backpack 20 watt SSB CW AM HF transceiver assembled is selling for $499 on Ebay . TX Frequency Coverage BAND 1: 3.5 – 4.0 MHz, BAND 2: 7 – 7.5 MHz, BAND 3: 14 – 14.5 MHz, BAND 4: 21 – 21.5 MHz.  If they really wanted to compete it should cover all the HF frequencies.

The $1000 price tag for the Ten Tec 539 is too much (IMO), and at some point one must ask what are they really getting for that price?  $1000  for a HF only rig that only puts out 10 watts?  On comparison, clearly for the $1000 the KX3 would be a better deal than the Ten Tec 539 although with the options for the KX3 puts it well above the $1000 spot.

There are many fine used full coverage HF rigs for $500 on Ebay, some of them could be dialed down to 5 watts for QRP, others down to 10 watts. The SGC 2020 sells for $400 to $500 , the TS50 I seen sell for $450 or less and the IC 718 sells for $450 used, Ten Tech Scout $300 and up...

Agree 110%.  There are many excellent rigs in the under-$1000 price range, that do the same or more than the proposed new TenTec.  Yaesu's FT-450D has IF DSP and covers 160-6m, the FT-857 and FT-897 are "old school", but include VHF and UHF, plus 20W output for portable operation, FT-817 cover all HF, plus 2m and 70 cm for substantially lower price.  They are all proven, reliable radios.  Given, they have their quirks and limitations, but they are all excellent value-for-money.  Even if the new TenTec has substantially better receiver, I don't see how can they justify a higher price for essentially a "lesser" radio.  Just because it says "Made in USA"?  The demand isn't big enough for another radio in the same price-range.

What we really need is a basic, robust HF XCVR in the under-$500 price-range.  Something that can be used as entry-level radio for new hams (especially young one, who have limited budget), a portable radio that won't break your budget if you accidentally damage it during a hiking trip, or a back-up radio to keep in your shack or car that can be efficiently used with battery power "when everything else fails ...".

For the Ten-Tec 539 to make a profit , it must offer more than it's competition, ether in Tec or Fun!
The KX3 is BASIC box ,with costly option that puts it price way above $1000.00 and into the K+range.

Hi gang:
I see a lot posted about this mystery new QRP radio from Ten-Tec.  Of course, everyone is entitled to an opinion of what it should include or what it should exclude. Matters like keep
the sale price right, the IMD better than any other ham transceiver ever created etc. etc.
What you all miss is that Jack Burchfield and Al Kahn broke the commerical QRP ice back in
1968 with their set of modules which led to the PM-1, PM-2, and PM-3 transceivers, and
finally, The Argonaut 505 in 1971. (If this is a mystery to you, you can read all about the
developments in my new book THE FIVE-WATT QRP MOVEMENT IN THE US, 1968-1981, in PDF
format, from www.qrpdxpropagationantennas.com, free download.) Heathkit got into the party with the miserable HW-7 -- Doug DeMaw's response (among a long list of QRP projects and
articles he authored for QST) was to publish a whole new receiver section for the HW-7.
At any rate, by the time the 515 appeared with its improvements, QRP had taken off and was
worldwide and all the major contests had included QRP sections -- yep, DX contests especially!
The 515 could be improved to an 8-pole xtal filter by an external mod or by a few simple mods
to the current QRO transciever's IF board. Its audio is legendary. I still use my 505 and 515
and no 160 meters, but 30m can be added by a very simple 4-part mod to the 515. I never got any of the later Argo models -- didn't need anyting better.

OK, wandered off topic. What I wanted to say is that all of the speculation about marketing
strategies and cutting corners etc. is bunk. Burchfield could have retired years ago, but
he's hung on for a couple more and wanted to have one last crack at improving the Argo series. It is a labor of love -- he always was very much into QRP from the start -- and I can understand him not wanting to say "it is all over".  QRP can't end.

So, you IMD and tech guys -- get a new unit and run your tests with the latest solid state spec analyzers and scopes and tell us what you find about the merits or shortcomings of the design. Then we can judge for ourselves about the merits of it before buying one. Incidentally, excluding 160 meters violates no natural law about what ranges a transceiver should have -- I've known a ton of QRP'rs who could care less about 160 meters. When assessing the performance of a design, personal preferences might be interesting, but what it does is the important thing.

72, Ade W0RSP
