Will data from the K3 internal data mode decodes be available to an
external PC for logging and other purposes?

I don't think so as there is no way to capture the scrolling text to make it
populate into a log field. If you already have a computer connected for logging why wouldn't you just use a soundcard program that will allow you to do this? ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Mon Jun 18 10:58 , [hidden email] sent: >Will data from the K3 internal data mode decodes be available to an >external PC for logging and other purposes? > > Bob Benedict > KD8CGH >_______________________________________________ >Elecraft mailing list >Post to: [hidden email] >You must be a subscriber to post to the list. >Subscriber Info (Addr.

Hi Greg,
> I don't think so as there is no way to ... > ... soundcard program that will allow you to do this? Why would I want to use a soundcard program if I've got a good demodulator (RTTY, PSK) in the K3? I would have thought that the K3 can send demodulated data via the RS-232 to the computer and the computer would be able to send plain ASCII to the K3 for data mode transmission. If the K3 can not do this, I would vote that this should be on the future feature list. vy 73 de toby _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

This would be useful for remote control.

Given the increasing difficulty of producing a 45 baud 5 bit code,
having translation both ways in the K3 would be useful, even with a computer attached. And the K3 has what I expect to be a reasonably capable CW decoder, too. In any case, if the output of the decoder can be sent out the serial port, a larger display would be pretty simple. The capability of sending decoded data out the serial port would be most useful. 73, doug Date: Mon, 18 Jun 2007 17:42:17 +0200 From: [hidden email] Hi Greg, > I don't think so as there is no way to ... > ... soundcard program that will allow you to do this?

I might like to monitor the PSK waterfall while racking up big points with RTTY on Field Day. Another reason is to use what will probably be very good integrated programs that are built in. If any program supported the data stream it would not matter if the source was RTTY, PSK, TTY or CW. Today I use HRD (Thanks Simon!) with PSK Deluxe (integrated), MMTTY bridged in (PTT only) and CwGet (no connection).

FWIW: Wayne and Eric came to the No Cal Contest Club meeting this month and gave an incredibly detailed and comprehensive presentation of the K3, including some hands-on time. [Thanks, guys!] After the discussion of the digital and CW decoding into the text buffer, and more than somewhat tongue-in-cheek, I asked if the radio had the ability to upload Q's in the text buffer directly to LoTW. It honestly seemed like it could ... it can do most everything else! Alas, no -- but Wayne said he'd put it on "the list." I'm not going to hold my breath, I think there a few far more sensible things on "the list" to be considered, but in the discussion, I was just struck by, "And exactly what else can this radio do?" 73, Fred K6DGW - Northern California Contest Club - CU in the 2007 CQP Oct 6-7 - www.cqp.org _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Absolutely 100% correct. If I have to use a sound-card to do a digital mode with the K3 then there is no real advantage to the K3 over the K2. 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

No need for isolation / decoupling with the K3, it's built-in (not sure
about the K2). Another advantage is simultaneous dual-band reception *and* the ability to receive at least 4 kHz bandwidth (this is why I have the FM filter on order). I don't see any problem with using a soundcard as long as it is a decent one. I'm sure a digital I/O card could be developed as an option at a later date but compared to a card such as the Delta-44 I don't think you would see any difference. Of course I'll not be able to confirm this until my K3 arrives (hint !). Simon Brown, HB9DRV ----- Original Message ----- From: "Brian Lloyd" <[hidden email]> > > Absolutely 100% correct.

Yes, but even if it *can* do this, I'd bet that it is going to be encapsulated in a K3 protocol message like the output from other CAT commands, so you'd need a dedicated bit of software to display the output, and enter input, not a simple terminal program. -- Julian, G4ILO G4ILO's Shack: www.g4ilo.com K2 s/n: 392 K3 s/n: ??? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I think the number of conversions is the same, it's just a matter of whether the conversion is done in the computer or the radio. Since a computer has a more powerful processor, I would expect it to do a better job, if available. The value of the built-in encoder/decoder is to allow operation using popular data modes *without* a computer. -- Julian, G4ILO G4ILO's Shack: www.g4ilo.com K2 s/n: 392 K3 s/n: ??? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I *SERIOUSLY* doubt that Elecraft would leave the digital world once the low IF has been sampled, except for the loud speaker / head phones / line out.

The final filtering takes place in the K3's DSP as does the demodulation. Don't be fooled: all the modules are still there. It is just that some of those modular functions are now performed in digitally in DSP. If you draw all the functional blocks, e.g. gain, filter, mixer, oscillator, they are all still there in DSP. If you then go to a soundcard you are now adding another conversion and a third IF. The K3's second IF (DSP) does its conversion and filtering but then does a conversion to a third IF, including a conversion from digital back to analog. We tend think of this as audio but it really is not. It is a third IF with no control over the AGC. The final amplification, filtering, and demodulation now takes place in the computer's DSP. Let me put it another way: one of the reasons that the Elecraft receivers work so well is that they do fewer conversions and use lower IF frequencies so that they can put good filtering as far forward in the chain as possible. This gets rid of products that could cause IMD in later stages. (The IMD may still be present in the stage but if you get rid of one of the offending signals you won't experience the IMD.) What you are suggesting is that we negate one of the advantages that Elecraft has built into the radio. This seems silly to me. My interest in radio is data communications. It may just be the equivalent of instant messaging, e.g. PSK31, or it may be something more complex, e.g. IP over PACTOR-III (OFDM). The K3 is [almost] unique in its ability to do the demodulation in its DSP and have that process optimally coordinate with the rest of the stages in the radio, i.e. it will do the best possible job with the signal. Frankly, I wouldn't want to give that up. I want a whole boatload of demodulators there in the K3's DSP with access coming out to me in some convenient fashion -- like on an ethernet connector.

Exactly the case. With the built-in decoder you can take the K3 someplace portable

I don't agree - with CW you tune by ear, for PSK31 / RTTY you need a visual
indication. You're also assuming that the other stations are using PSK31 (not PSK63) or RTTY with 45.45 / 170Hz. Also it's common to decode digital signals which are not visible on a waterfall. Myself I'm planning on a decent 12" laptop for portable ops with my IC-703, many now offer up to 4 hours on a standard battery. If you can get a K3 out portable with the required power supplies and associated gubbins then adding laptop is a doddle.
