I just loaded Wayne's latest K3 firmware, and (in addition to other neat
stuff), there is a new PTT mode for CW which does this: 1) When PTT is open, hitting the key gives you sidetone but no RF. 2) When PTT is closed, you go into TX mode for as long as it's closed. Hitting the key then makes sidetone and RF. This is in addition to the regular semi- and full-QSK modes. AND, if you are in semi- or full-QSK mode, closing PTT still puts you in transmit mode. One day from "clamor on reflector" to beta testing! -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Do you mean "...closing PTT has no effect because QSK already has you in transmit mode?" Or while in QSK mode must you closs PTT in order to transmit? de Joe, aa4nn >This is in addition to the regular semi- and full-QSK modes.

That's all. In PTT mode, you must close PTT, which switches to TX mode, and then hitting the key transmits. If you are in QSK mode, closing the PTT switch will put you in transmit mode.

Joe and all,
I have the same questions. Since no one has explained the difference between 'Transmit mode' and "the K3 is now transmitting since QSK has been started with a keypress" - I would believe that the PTT input is redundant when in QSK or Semi-break-in modes. Yes, a little clarification (or language lessons) seem to be appropriate here. How is 'Transmit mode' different from 'transmitting already because the key was tapped'? Does closing PTT when in QSK mode inhibit a return to receive until the PTT is released? - that is the only thing I can think of. It certainly seems that the generation of RF is controlled by the paddles in any case (except for the new TX inhibit condition). A few things were clarified, but confusion still reigns high in my mind. 73, Don W3FPR 73, Don W3FPR Joe, aa4nn wrote: > Do you mean > "...closing PTT has no effect because QSK already > has you in transmit mode?" > > Or while in QSK mode must you closs PTT in order to transmit? > de Joe, aa4nn > > >> This is in addition to the regular semi- and full-QSK modes.

Vic,
That clarifies part of it - but 'transmit mode' apparently is not defined as "the presence of RF" - it simply means that the K3 will not return to the receiving condition (if I understand what you mean correctly). Please confirm or provide an alternate explanation of "Transmit Mode". 73, Don W3FPR Vic K2VCO wrote: > Joe, aa4nn wrote: >> Do you mean >> "...closing PTT has no effect because QSK already >> has you in transmit mode?" >> >> Or while in QSK mode must you closs PTT in order to transmit? >> de Joe, aa4nn > > There are three modes available. > > 1) PTT > > 2) Semi-QSK > > 3) QSK > > In QSK mode, you just hit the key to transmit.

Think of non-QSK (semi break-in) with the key up between dits in the letter H. You are in transmit mode -- the receiver isn't on -- but no RF is being generated. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Transmit state: it's 1954, your knife switch has the antenna connected to the transmitter, the B+ of the transmitter is on, the receiver is silent. Press the key and you transmit. > Yes, a little clarification (or language lessons) seem to be appropriate > here. > How is 'Transmit mode' different from 'transmitting already because the > key was tapped'? If you are in QSK or Semi QSK, tapping the key PUTS you in transmit state, then generates RF, then takes you back to receive state. If you are in PTT mode, then you MUST first close the PTT before you can transmit. It's not automatic, like QSK or semi. > Does closing PTT when in QSK mode inhibit a return to receive until the > PTT is released? - that is the only thing I can think of. Closing the PTT regardless of mode switches you to transmit state. It mutes the receiver (except for the sidetone) and activates the amp key (or whatever you use this output for, like switching VHF preamps). Then when you press the key it transmits. The difference is that in PTT mode the key can't put you in transmit state -- only the PTT switch can do that. In QSK mode, it's all automatic, but the PTT switch is still active and can put you into transmit state and keep you there for as long as you hold it. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Please confirm or > provide an alternate explanation of "Transmit Mode". That's right. The K3 can be in Transmit Mode with or without RF being transmitted. Other than RF emitting from the antenna jack the rest of the radio is in transmit mode, and not in receive mode. Back to the original discussion ... When the K3 is in CW PTT-only mode, i.e., QSK/SEMI are disabled, then asserting PTT puts the K3 into transmit mode. RF can then be emitted in accordance with the PADDLE or KEY inputs. When PTT is released, the K3 goes back into receive mode regardless of the PADDLE or KEY inputs. 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I seem to be missing the point of this PTT CW keying thing... Is it for
transverter/linear/mast head pre-amp use on VHF/UHF? A useful feature that was mentioned a long time ago (and put on the back burner I think), was adding a programmable transmit feature to one the "PF" buttons to give a carrier for linear/ATU tuning. I have this feature on my Kenwood TS-480 and find it invaluable. Pressing thw 480's PF button toggles a carrier on and off (regardless of mode), the carrier level can be adjusted while it's transmitting via the normal power setting route and can be set anywhere from 5 to 100 Watts in one Watt steps (the power setting limits of the 480). The power level is stored and occurs regardless of the main power level setting, so for example if I'm set for 5 Watts of QRP CW, pressing the button gives me 10 Watts for the external MFJ auto ATU. If I'm using my valve linear and have the 480 set at 25 Watts on SSB, pressing the PF button gives me 10 Watts to tune the linear with. This is similar, if not the same functionality, as those external 3rd party button boxes do for the Yaesu FT817/857/897 rigs Has this use of one of the three PF buttons been included yet? 73 Dave, G4AON _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I too would like to be able to send low power RF to my SGC to tune it.
I'm NOT asking for a f/w change right now, my suggestion below requires it be incorporated with the capability of controlling the KAT3 on individual antennas. A menu option that sets the power you wish to use. The function is invoked via the 'ATU TUNE' button and sends a carrier out the current ANT socket for as long as the button is pressed (is it possible to press a button in this way?). This would save using one of the PF buttons and since with the KAT3 'off' for that antenna, the button is 'free' it's a logical, labelled choice (external 'ATU TUNE'). I think there was discussion of being able to key this via the ACC connector and that would work well for me too - using a push button on a lead. It's possible to put the Yaesu FT-897 into 20W carrier transmit by grounding a 'little brown wire', indicating the rig is on battery power (limits power to 20W) AND grounding the ring of the ACC connector, intended to 'key' the rig. I'd like to be able to use a lot less power than that, the SG-237 will tune up on 3W.

This capability is exactly what I'd like to see, too. I'm actually
using a manual external tuner on ANT B. I can tune using as little as 1W. Ideally, I'd like the option (which David didn't request) to see the SWR when tuning. In K2 terminology, I'd like to have CAL S mode automatically selected on one antenna socket and AUTO on the other. The ability to set the power level for tuning independently of the main power control would be a real bonus. -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

Yes, watching the SWR would be good (I'd assumed that would be there).
I use an ext. SWR meter, but watching the SWR as the SGC tunes via the K3 display would be much nicer.

> I seem to be missing the point of this PTT CW keying thing...
> Is it for transverter/linear/mast head pre-amp use on VHF/UHF? I don't know, but that certainly hasn't been the focus of our discussion of this feature. It is simply providing PTT-only control of transmission for the CW mode, just like PTT works in SSB. The transmit mode is 100% controlled by the PTT line rather than transmission being turned on and off in the QSK or SEMI break-in modes by PADDLE or KEY closures. Some CW operators prefer PTT-only over QSK or SEMI break-in. Some SO2R controllers and other station control units depend on this feature. I understand that it is required for some VHF/UHF transverter operations. CW PTT-only (i.e., QSK and SEMI break-in are disabled) is on every transceiver except the K2, as several postings have reiterated recently on this reflector. > A useful feature that was mentioned a long time ago (and put > on the back burner I think), was adding a programmable > transmit feature to one the "PF" buttons to give a carrier > for linear/ATU tuning.

The TUNE button on the K3, as on the K2, transmits a carrier at the power level set on the POWER control. There is not yet a dedicated button or even a Function that could be assigned to a PF button, that transmits a carrier at a reduced power level. With the KAT3 installed, though, you can tap ATU and get a five-watt carrier transmitted to tune the KAT3. I find myself using that button for just the purpose you describe. It transmits 5 watts and auto-tunes the KAT3 to match the input circuit of my linear amplifiers. While I certainly don't need those inputs (since they are nominally 50 ohms), I do it anyway just to make use of the five watts, as you desire, for preliminary tuning of the linear. I then follow that with the TUNE button and the POWER set at, say, 50 watts for final tweaking of the linear for 1500 watts output. BTW, there are 10 PF buttons now on the K3, not three as on the earlier front panel renderings. PF1 and PF2 are hold operations on the RIT and XIT buttons, while both tap and hold operations on the M1-M4 buttons can be used for PF functions instead of message buffers (on a one by one basis). 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
