[Premium-Rx] Receivers

[Bob Betts]

Hi John and Gary:
Not sure what Bob Sherwood had to say about them, but I'm super pleased with my Ten Tec 340. I had done some side-by-side tests with a W-J 8711 (HF-1000), wth them sharing the same antennas through a multicoupler. It's a tough job, but somebody had to do it...lol. That first go-around was a fun memorable night, which was repeated several times over 2 weeks. I later included a pair of W-J 8718's and two Racals, 6790 and 6793. Sorry, but the Icom never got on my "to buy" list. Too much $$$, but it has been on my "wish" list...maybe some day.
Anyhow, I'll go straight to the end first. The 340 wins in all categories except for a few occasions when the 8711 eeked it out a bit (very subjective value judgment). By and large, it was the TenTec that lead the pack...sometimes by a squeaky hair and sometimes by a significant amount. The 8711 was always right there...many times too close to call, but I'd have to give the nod to the 340. Considering the Racal's and older W-J's are a few generations removed, they really held their own. Racal noise floor is almost nonexistent on the very weak DX stuff, making its intelligibility, way down in the mud, superb. Considering that the 340 has DSP processing, I'd say that's quite a badge of honor. Likewise, the 8718's really held their own. Somewhere around 30-years-old, those icons really play well.
My testing involved near-in flame throwers against various Hams and Intl b'casters on 40/41 meters, AM b'cast band DXing, NDB's, 12/10 meter Hams, and careful notice of WWV as an indicator beacon on 5, 10, 15, and 20 MHz.
I should tell you that all of these guys have been on the service bench for instrument specing...some of them many times. But test equ numbers are just numbers. All due respect to Bob Sherwood who had done an amazing job of tabulating all that data. But reading the torque, RPM's, G-force, and zero to 60 specs is never as much fun as sliding behind the wheel.
So there's a whole bunch of rambling words from a very memorable effort. The radios are scattered in different locations now, but it is certainly a very repeatable test setup. Maybe in mid-winter I'll do something like that again.
Anyhow, I hope you've gotten something from my (very) subjective evaluation (read, opinions).
BTW: None of those radios are different enough to be considered undesirable.
 
Maybe someday I'll get that R-9500...
 
Happy New Year and good signals to all,
 
Bob, N1KPR

John,

Head over to www.sherweng.com and look at the receiver tests.

I think the intercept and instantaneous dynamic range tests really show the difference between the two at HF.

I have just been drooling over a couple of commercial receivers and was 
wondering if anyone on the list has one or both of these receivers and could 
comment on their use.
The receivers are Icom R9500  and the Ten-Tec 340.
Comments please.
