I have a test data sheet from Sherwood Engineering that shows the IC-746 having 20KHz (99dB) and 2KHz (70 dB) Dynamic Range Data. Also there is the IC-746Pro data which 20KHz is 97dB and 2 KHz is 70d
The thing I find impressive in the Sherwood report is that 50 year old technology (AKA R-390A) does better then most of the current rigs... 73, Steve FYI the Omni VI+ 20KHz test data is 97 dB and 2 K
R390A, Drake R-4C etc, etc. and of course Orion It is my beleif that all manufacturers (By Now!) know well .. how to build a superb radio. Especially when it comes to RCVR performance. They just don'
Unfortunately, the R-4C as it came from Drake was not a very good receiver in almost every measure we now consider important. Downright awful actually. Which isn't to say that I don't love mine dear
Aaaahhhhh! But do you have a full Sherwood modified R-4C (By Sherwood himself)??? It's wonderfull.... ;-) Lee _______________________________________________ TenTec mailing list TenTec@contesting.com
Sinista, you are suggesting feedline losses, not tuner losses - right? ! Just to clarify LDG is not causing the attenuation! ;-) My 2 cents, I am a "fit and finish" guy but the way the Icoms and MPs
The IC-746 PRO does not allow for installation of any extra filters. It's last IF stage is DSP just like the Jupiter although I suspect it has a more modern processor. In fact, it's processor is newe

Yea, noticed that too. The top 10 rigs, in order of 2kHz Dynamic Range Data, as per this report on receiver performance are: Orion (1kHz roofing filter) = 92 dB Drake R-4C (600 Hz roofing filter) = 8
Re: firmware updates. A Ten-Tec rep told me some time ago that the Argonaut is a finished product and no further updates will be forthcoming. I don't know whether this injunction applies to the Jupit
I suppose its resale value will drop substantially the day you unpack it.>> -- I wasn't aware that iCom announced a 746ProII. Is that a non-U.S. market only for the time being? I haven't seen any adv
Wow, is this true about Ten-Tec cutting off firmware updates after a period of time? If that is indeed the case, it certainly detracts from the "value" of the impression that these radios are never r
Dennis, You cannot make firmware updates forever, after you exceed the available memory for such. The microprocessors regularly go out of date, and semiconductor manufacturers discontinue their avail
Stuart, All good points you make, and yes, a radio with such limitations as you point out can't take endless amounts of updates, which makes me wonder about the first poster's point of the the Jupite
Dennis, A practical reality for companies of limited size such as ham radio companies, is that the resources of the company must swing to other product lines, and there are not unlimited software res

There's a vast difference between a given radios "update lifespan" and the radio's actual lifespan. The first easily described, when the firmware is acceptable to as many users as possible within the

I bought a used 746 from a local ham who had loaded it with filters. I'm VERY happy with the 746 on 6 meters, but don't use it on the low bands because I have other radios that are better. I tried to
Jim, There is a big debate over Jupiter vs ICOM 746PRO, and as it is the Ten Tec reflector, it is obviously biased toward the Jupiter. I am coming more to think the Jupiter would be a good rig for th
