I think the 6 is a very capable and FB little rig. The only extra item I purchased was the 700 HZ roofing filter
The receiver is fantastic, one of the most pleasant to use that I've had my hands on, I love it.ï¿½ Nice and quiet, It has very good specs, the DSP filter is amazing, and It has excellent close in signal rejection for contestors.ï¿½ Tuning in a station near the noise level and cranking down the filter to 100 HZ leaves only the station, nothing else, andï¿½ with smooth nice sounding audio and no filter ringing.ï¿½ In this regard my Pro III isn't in the same ballpark.ï¿½ The buttons and TMB switch may seem unusual, but are very easy to master and makes perfect sense logically and ergonomically.ï¿½ï¿½ The transmitter performs as expect capable and easy to use.ï¿½ It interfaces to your rig controlling logging software easily and without any hiccups, I use ACLog.
There are several in the Group, and I was lucky to play with one during FD a few years ago, and was convinced I had to have one.ï¿½ Paul Stroud, AA4XX, wrote an excellent report on it on QRP-L (I think) a couple years ago.ï¿½ It's a must read if you are considering a new rig.ï¿½
The complaint list is small and minor for me, here tis:
No XIT, has RIT, but XIT is much easier for me when Fox hunting or DX chasing.ï¿½ It has dual VFO's however, making this complaint kinda nonsensical..
No 60 or 12M, no biggee but I'd like to have 12.
The keying is a tad choppy when using an external keyer like the EZKeyer.ï¿½ The rig chops the first character a bit, the sidetone as well as on the air, plainly noticable but still useable. I like to use the EK3 with it and overcame this issue by keying it from the EK3's MUTE line, works perfect.ï¿½ The internal keyer sounds pretty good in that regard tho. You can mitigate that with the weight control on your favorite keyer if it has one.
It's a great little rig and I'd buy it again. I can recommend it for both the shack and the field. Here's a link to TT's brochureï¿½

I too can add to this. Let me preface by saying that I feel entirely spoiled by my KX3, and in my opinion, the 539 is not nearly in the same class. Nonetheless, it is a fine rig. The tuning knob is great, CW sound is good, and filtering is very good. There is some artifact with the headphones, and I really DON’T like the headphone jack at the back of the radio. 3.5 mm jack seems like it would have been more appropriate for the phones.toggle quoted messageShow quoted text
The CW problem of “clipping” can be solved by putting zero resistance in the keying line. I get variation even from key to key, and I can ameliorate the problem if I clean the contacts. An external keyer has way too much resistance in the line to avoid the problem. I found the keying problem very distracting, at least until I figured out the problem. Then the problem returns with even a tiny amount of oxide on the key contacts.
I agree with Terry regarding XIT and the lack of 12 meters. I also think it would have been a great coup to put “dual watch” instead of a simple split, in the same way the KX3 does. Dual watch is the one feature that keeps me coming back to the KX3 for anything beyond rag chewing. I also would suggest that it’s a very heavy rig compared to many others, and it has big open vent slots on the top of the radio, making it less than my ideal rig for portable ops.
The radio is more comparable to the Elecraft K2, in many ways. But you won’t touch an Elecraft rig with the same functionality for $850.
So that’s my 2¢, for what it’s worth.

Terry and All,
Boy Terry, you convinced me all over again that I wouldn't want one of those rigs!
Yes, I am sure it is a competent radio in most respects. However, the negatives are pretty glaring in my viiew.
No XIT is a biggee! Not for everyone perhaps, but if you chase DX it probably is. When you are QRP you need both the RIT and XIT to sneak into spaces where you can be heard.
I am still totally astounded that the rig omits 12 and 60 meters. Maybe most don't venture onto 60 meters yet, but they may eventually. 12 meters is a critical band, again if you are at all interested in DXing. As a WARC band, it is also a refuge from contests you don't care to participate in.
As an aside, last year at Dayton the new Ten-Tec owners were very visible at our FDIM gathering. One of them overheard me commenting to someone else about my 35 year romance with Ten-Tec that had sort of ended. He was very interested in hearing more of what to say, so I told him. When I got to the part about questioning the rationale of omitting 12 and 60 meters on the Argo VI, he nodded his head as if he totally agreed with me. I think his reaction was sincere and not patronizing! I also have a big problem with the ergonomics on many of the more recent Ten-Tec offerings, and he seemed sympathetic with those comments as well.
I wasn't even aware of the keying issue you mentioned, but that would be a deal breaker for me also. Actually, that rather surprises me.
One thing you didn't mention was that, for Field Day, the Argo VI isn't that great a choice considering its RX current draw. If you plan to operate 1B-Battery, you may want to use a different rig.
A lot of the issues I have with the Argo VI is that I think they were intent on "simplifying" the radio. I think they overdid it! The front panel is bare bones to a fault. For example, I really want fast access to some adjustments (like power and keyer speed), and you no longer get that on a lot of Ten-Tec rigs. I have a prediction as to when stripped down front panels like this will make sense. That's when we "marry" radios to voice recognition software! Then you can just speak a command to make various adjustments on the fly! Until then, we need to get our fingers on certain adjustments, and quickly.
Notwithstanding the above, I have listened to an Argo VI, and it does sound very good! If you can get around all the nit-picking, it's a pretty good radio!
