[Elecraft] Workaround for providing automatic SSB CW VFO offset

2009-06-12 Thread Ralph Parker
...VFO automatically offset... when switching between SSB and CW...
On VHF and UHF, SSB and CW are used interchangeably...

Good work, Bill!
Non-6m ops don't quite understand the problem, complicated by the fact that
normal CW is on LSB, making us ex-Yaesu drivers crazy.
I've solved the offset problem for now by using my PRO III on 6m
(has the spectrum display, too :-)

I have managed to implement the VFO shift when changing modes to/from CW in
the next version of KComm.

Re: [Elecraft] Workaround for providing automatic SSB CW VFO offset

2009-06-12 Thread Bill W5WVO
I have discovered one gotcha in my workaround, and that is the inability to 
lock the B VFO knob -- the KNOB, not the VFO -- because if you accidentally 
touch it, you lose the 700 Hz offset. I've been training myself not to touch 
it, 
but it would be nice if there was a way to lock it down so it wouldn't do 
anything. Removing the knob and epoxying the shaft seems a little extreme. ;-) 
Perhaps a function that does this could be implemented that could be invoked 
from one of the PF function buttons.

Of course, all of this is moot if the VFO mode-switching behavior gets fixed so 
it works correctly in the first place. I have faith that Wayne will eventually 
get to it. But the Elecraft folk do tend to respond to the squeakiest wheel 
first, so if this behavior is at all important to you, please let Wayne know. 
Otherwise he will continue to think I'm the only nutcase who cares about it. :-)

While we're on the subject -- Is there anyone else here besides me who thinks 
that the normal CW tuning behavior should reflect the default SSB sideband 
for 
a given frequency band? In other words, instead of always tuning like LSB, the 
CW mode would tune like LSB on 160, 80, and 40, and would tune like USB on 
all 
other bands. CW REV would reverse this default correlation. Seems more 
intuitive to me than the way it is now.

Re: [Elecraft] Workaround for providing automatic SSB CW VFO offset

2009-06-12 Thread Don Wilhelm
Bill,

I for one have to disagree with you on the CW sideband item.
 From day one of my hamming days, I have always wanted CW to tune so the 
higher pitches were higher in frequency than lower pitched signals 
(blame that on my early elmer).  So I have come to relate the audio 
pitch to the relative frequency - which means LSB CW for all bands.

Yes, I know SSB is different, but SSB is different than CW.

Hello Bill,

I am with you on needing a way to be able to switch back and forth from CW to 
USB on 
6m, and I also use CW-R for this.  However, I like to keep my B VFO free for 
other 
things - like quickly QSYing off the calling frequency by just switching to the 
other 
VFO.  I think the neat way to switch to CW and back to SSB again would be to 
somehow 
define your steps as a macro and program it into some hot key so you could 
automatically do all the steps quickly and without error by just pressing a 
single 
button.  I don't know if this is possible with the K3, but I imagine that it is.

While we are on the subject, I still would like to see use footswitch operators 
be 
able to send CW to SSB operators, like the VOX people do ;-)

VY 73, Lance

Bill, you can lock VFO B by going into BSET mode, then holding LOCK. If 
the VFOs are linked, this preserves VFO B tracking.

Re: [Elecraft] Workaround for providing automatic SSB CW VFO offset

2009-06-12 Thread Bill W5WVO
Wayne,

This is why I emphasized the KNOB, not the VFO. When you swap VFOs A and B by 
pressing the A/B button, the locked status follows what was originally VFO B 
and 
now becomes VFO A. What we want here is for the VFO B KNOB (i.e., the middle 
one) to stay locked, regardless of which VFO frequency it is controlling, 
because moving it changes the 700 Hz offset when VFO B is not locked. If the 
locked status didn't follow the frequency from VFO B to VFO A, it would work to 
prevent accidentally corrupting the offset. However, that is clearly not the 
way 
LOCK was designed to work.

[Elecraft] Workaround for providing automatic SSB CW VFO offset

2009-06-11 Thread Bill W5WVO
A number of VHF ops on the list (myself included) have been lobbying for some 
time for a feature that is standard on most or all HF+VHF Ikensu rigs: the 
ability to have the VFO automatically offset by the amount of the BFO pitch 
when switching between SSB and CW. This capability is typically of little 
interest to HF operators, where SSB and CW are rigidly separated into two 
distinct sub-bands. On VHF and UHF, SSB and CW are used interchangeably, as 
needed, on the same (SSB) frequencies.

I've already had extensive discussions with Wayne about this; the problem is, 
due to the software design architecture of the K3, it's not as easy to 
implement as it sounds like it should be.

The performance objective for switching from SSB to CW (CW to SSB is simply the 
reverse) is for ONE button tap to accomplish:

  (a) shifting the VFO frequency up (or down) 700 Hz (nominal pitch)
  (b) switching the K3 from USB to CW REV (or from LSB to CW)
  (c) bringing into play a pre-configured set of CW characteristics that go 
with the transmission mode

The workaround I've come up with accomplishes this, at the expense of having a 
free VFO B to play with. On VHF/UHF, however, there is virtually no split 
operation (except satellites), so this isn't as big a deal as it sounds like.

Here's how to do it, assuming USB and a pitch offset of 700 Hz (substitute your 
own pitch setting if not 700):

(1) Set MODE to USB, and set up all desired RX characteristics for this mode in 
the normal fashion.

(2) Set display resolution to FINE so it displays Hz (three decimal places).

(3) Tap A/B button, and repeat Step 2.

(4) Now set each VFO in turn (select using the A/B button) such that one is 
zeroed out (xx.xxx.000), and the other displays xx.xxx.700.

(5) Hold SUB and notice that the display says LINK. The two VFOs are now locked 
together and will track 700 Hz apart.

(6) Use the A/B button to select the VFO with the +700 Hz offset. This will be 
your CW VFO.

(7) Set MODE to CW REV, which will give you the same tuning direction as USB. 

(8) Set up all desired RX characteristics for this mode in the normal fashion.

This completes the setup. From now on, a tap of the A/B button will switch from 
USB to CW REV or from CW REV to USB, and the VFO will automatically be set to 
the correct frequency, removing the requirement of retuning to acquire the 
signal.

RIT can still be used in the normal manner, but the offset will be carried on 
RX when switching from one VFO to the other. Depending on what you're trying to 
do, this may or may not be a good thing. Just be mindful of the behavior.

Please critique these instructions if you find anything unclear.

 I've already had extensive discussions with Wayne about this; the
 problem is, due to the software design architecture of the K3, it's
 not as easy to implement as it sounds like it should be.  
 
 The performance objective for switching from SSB to CW (CW to SSB is
 simply the reverse) is for ONE button tap to accomplish: 
 
  (a) shifting the VFO frequency up (or down) 700 Hz (nominal pitch)
  (b) switching the K3 from USB to CW REV (or from LSB to CW)
  (c) bringing into play a pre-configured set of CW characteristics
 that go with the transmission mode 
 
 The workaround I've come up with accomplishes this, at the expense
 of having a free VFO B to play with. On VHF/UHF, however, there is
 virtually no split operation (except satellites), so this isn't as
 big a deal as it sounds like.   
 
 Here's how to do it, assuming USB and a pitch offset of 700 Hz
 (substitute your own pitch setting if not 700): 
 
 (1) Set MODE to USB, and set up all desired RX characteristics for
 this mode in the normal fashion. 
 
 (2) Set display resolution to FINE so it displays Hz (three decimal
 places). 
 
 (3) Tap A/B button, and repeat Step 2.
 
 (4) Now set each VFO in turn (select using the A/B button) such that
 one is zeroed out (xx.xxx.000), and the other displays xx.xxx.700. 
 
 (5) Hold SUB and notice that the display says LINK. The two VFOs are
 now locked together and will track 700 Hz apart. 
 
 (6) Use the A/B button to select the VFO with the +700 Hz offset.
 This will be your CW VFO. 
 
 (7) Set MODE to CW REV, which will give you the same tuning
 direction as USB. 
 
 (8) Set up all desired RX characteristics for this mode in the
 normal fashion. 
 
 This completes the setup. From now on, a tap of the A/B button will
 switch from USB to CW REV or from CW REV to USB, and the VFO will
 automatically be set to the correct frequency, removing the
 requirement of retuning to acquire the signal.   
 
 RIT can still be used in the normal manner, but the offset will be
 carried on RX when switching from one VFO to the other. Depending on
 what you're trying to do, this may or may not be a good thing. Just
 be mindful of the behavior.   
 
 Please critique these instructions if you find anything unclear.
