K3 DSP bypass
Locked
 
|
Can the DSP in the K3 be bypassed? In other words, can it be operated as a conventional superheterodyne receiver without any processing? Would be interesting to do A/B comparison testing. Years ago I had a Ten Tec Omni 6 Plus, a great radio except for the horrid DSP hiss. I always wished I could somehow bypass or defeat the DSP just to see how much better it would be to listen to through a long contest without that awful hiss.

Last really quiet production rig I used was a TenTec Corsair - fully
analog. I should have never sold it - best 160 rig I ever had. Dead quiet winter bands and signals would just jump out at you - sort of like a signal breaking squelch on FM.

Not without a big hardware modification. The detection (do we still call
it that?) -- conversion to audio is done in the DSP. And a lot of other stuff. On 3/3/2014 5:32 PM, GDR wrote: > Can the DSP in the K3 be bypassed?

Here is the latest 100% Analog Radio on the market today.

How is a radio with direct digital synthesis and DSP processing 100% analog?

That's one of those items where if you have to ask the price,..... you
can't afford it. 73 de Ray K2ULR On Mar 3, 2014, at 9:28 PM, [hidden email] wrote: > Here is the latest 100% Analog Radio on the market today. > > http://www.hilberling-usa.com/ > > Even Rob Sherwood raves about it! > > BTW, don't worry about the price.

$18,000+! And for more than 4 times the price of a loaded K3, you get
4dB better close-spaced dynamic range. That is only $3K per dB. On the plus side, they do come in 4 colors, vs. the K3's one. I'm sure people will be lining up to buy them. 73, Scott, N9AA On 3/3/14 10:42 PM, Ray Sills wrote: > That's one of those items where if you have to ask the price,..... you > can't afford it. > > 73 de Ray > K2ULR > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Maybe Elecraft will offer different color faceplates for the K3?
Anyone like Pink?...or Purple?...or ? TIC folks...... Gary On 4 March 2014 13:50, Scott Manthe <[hidden email]> wrote: > $18,000+!

I don't think the LCD will work well after a good coating of Rustoleum!

The LCD will work just fine, but the customer may not be able to see the
icons and values. 73, Don W3FPR On 3/4/2014 12:54 AM, WILLIS COOKE wrote: > I don't think the LCD will work well after a good coating of Rustoleum! > > Willis 'Cookie' Cooke, TDXS DX Chairman > K5EWJ & Trustee N5BPS, USS Cavalla, USS Stewart > > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

The K3 is an SDR transceiver. That means that the filtering,
modulation, and demodulation (as well as noise reduction and many other functions) is done in the digital domain. One cannot disable the DSP processing of the K3 without disabling the entire transceiver for both transmit and receive. If one wants to use the K3 as a superhetrodyne receiver, the 8 MHz IF output could be used (with the KXV3 option) and send it to an analog receiver capable of receiving that frequency. I am just not certain of the utility in doing that - the K3 DSP enables a lot of function that is not available in an analog receiver of comparable price. I cannot comment on the "awful hiss" that you refer to. It is not a result of DSP processing, but may be a result of shortcomings in the software (firmware) used for the processing. I would suggest that you listen to a K3 for a while before making a decision. 73, Don W3FPR On 3/3/2014 8:32 PM, GDR wrote: > Can the DSP in the K3 be bypassed?

I don't think it's possible. Some dsp functions are not available with AGC off. Sometimes it's quieter with AGC off and reduced rf gain but not always.
After 3 years, the best way to reduce hiss for me is to reduce hi cut (on ssb) sometimes to 2.4,sometimes 2.1. I would think in a contest you would be running narrow anyway but wouldn't want AGC off.

Can you say "masking tape?" I knew you could.
