Yes, a magnetized screwdriver is very handy for guiding the screws to
their holes without having to fumble with them.  (There are a LOT of
screws!)

Some people pre-sort all the screws. I just dumped them and the
washers into a shallow pan and hunted through them as they were called
out. But do pay close attention to the screw lengths and washer types

Yes, PITCH would seem like a good choice for the signal pitch
adjustment. Or perhaps signal pitch could be made an additional option
for the RIT/XIT control when RIT/XIT is off? (RIT is already an
optional coarse tune control and has also been suggested as an
optional band switch.)

For sidetone pitch adjustment, perhaps MON could allow it with a 2nd
push? Then you'd have sidetone pitch and volume with a single control.
Makes sense?

Brett, 

I'm not suggesting that offset pitch and sidetone pitch be different.
They are the same. 

I'm suggesting that sometimes you want to adjust this pitch by
listening to the sidetone and sometimes you want to adjust it by
listening to the received signal. Currently you can't hear the signal
while you adjust PITCH-- the received audio is blocked.

Why would you want to vary the signal pitch? Because a different pitch
can provide better copy under different reception condtions. But it's
pretty hard to tell what that optimum pitch might be without listening
to the signal as you adjust it, right?

 Now, you can vary the VFO in order to change the signal's pitch, but
then you have detuned it. I want to vary the pitch of a signal without
detuning it. The K3 can do this, only it doesn't let us hear the
signal while doing it.

Which brings us to the old fashioned way to adjust the pitch of the RX

keeping the signal where you want it in the passband.



Keith, 

Say you have managed to tune in a very weak signal to the very
optimum... no further adjustment on the K3 controls could improve it.
Except, your offset is 400 Hz; but some combination of QRM, noise, his
code speed, keying characteristics and your own psycho-acoustics would
make it easier to copy at, say, 800 Hz. Turning the VFO (or RIT) 400
Hz will put him out of the passband (then use SHIFT, etc, i know...). 

Why not just be able to vary the pitch; the K3 keeps the signal
centered in the passband. This seems like the obvious simple solution.

I wonder if it would be possible to just have received audio when
PITCH is engaged. Then we could turn the sidetone volume to zero and
observe the pitch variation of the received signals directly. It is a
little clumsy  but I wouldn't mind and I don't think this feature
would upset anyone with more control functions, etc.

I don't adjust the sidetone level very often. Not sure I'd like to
have it vary with the AF Gain. I think I like having it as a reference
audio level. Mine is set at 25. 

What I would like is the option to adjust the PITCH without hearing
the sidetone. In other words, listening to a weak signal I want to
adjust it's pitch (offset) for best copy. Different signal conditions
can warrant the use of different pitches for optimum copy. But you
can't do this with the sidetone overriding the received audio. Even if
you set the sideone level to zero the received audio is blocked
whenever PITCH is on.

I've been very happy with the AGC-NR on the K3, so turning off AGC is
starting to become a last resort for me. And the configurable AGC
parameters give you a lot of options, not one AGC fits all. (I do
adjust the RF gain even with AGC on.)

I also give signal reports corresponding to the s-meter reading. This
is convenient with the K3's absolute meter mode (doesn't matter
whether attenuator or preamp is on). It's just for my own interest,
comparing signal strengths at the antenna terminals. Can't see why I
wouldn't want to record them as long as I'm going to the trouble of
making RST notations anyway.

Whether or not the sidetone level tracks the audio gain is of little

We turn off the AGC, so its characteristics are of no consequence.

We give *real* signal reports based on what we hear, not on what an
S-Meter tells us.

There's a reason why a great many radiomen have preferred to operate
that way over the years. For many of us, it's the easiest, fastest, and

Frequently it's easier to do the simple stuff ourselves instead of

Yes, Don, I agree completely. Forget about the labels entirely and
just learn them by key position. However, I went with a vertical
scheme vs your horizontal one...

The first keypad column (1,4,7) is 160, 80,  40. Second column is 20
to 6 (6m stands apart way down there on the zero key); third column is
the warc bands. 

I figure if I can keep track of forty-some keys on a keyboard without
looking then I can memorize the positions of ten band buttons on the
k3. Now my band locations just seem right! No label reading; no
mental translation... the buttons ARE the bands!

So, if the power goes out I can navigate the bands without even
needing to see the buttons. (Admittedly, there isn't much point to
navigating the band buttons when there is no power to the K3...)

It's really easy to update the firmware (or go back to previous

like the constant stream of fw revisions and enjoy installing them. 

Usually products which boast upgradeable firmware will have a revision
or two (for major bug fixes) then that's it. With Elecraft you get the
idea that they will be enhancing the operation of the rig, not just
fixing a few major bugs and moving on to something else. 

Having said that, I only install the updates when they involve some
feature that I'm interested in. I did the latest version because I'm
interested in the AGC mods.

I bet there are probably a number of firmware improvements since
version 1.7 which you would enjoy having. Have you checked the

Re: [Elecraft] K3: band enable/disable option ?

2008-07-21 Thread drewko1
I had suggested that the UP/DOWN buttons be made to operate on a
user-selectable contiguous range of memories, much like the Channel
Hopping scan function; but instead of an automatic scan the user would
be able to step through them with UP/DOWN. That way one could program
one's own band sequence: WARC, non-WARC, CW, SSB, etc. or skip bands
for which you have no antenna. You could also reverse the order as one
guy wanted (i.e., UP = longer wavelength, not higher freq). Also, you
could program your SWL bands, which currently do not play well with
BAND UP/DOWN.. 

Of course, I have no idea how feasible it would be to implement this.
But on the surface it seems like it would be a neat feature.

The BAND UP/DOWN control is not necessary at all because the K3 has a
number of convenient memory access functions with which you can get

Coming back to enable status for some band can be done via direct

You can set the KAT3 menu config entry to LCSet. Exit the menu then
tap ATU TUNE. You can set the L and C values individually with the A
and B VFO controls. But it doesn't seem to make any difference in the
AM received signal as far as I can tell. I'm using a 100' wire for an

Re: [Elecraft] BCB sensitivity [K3]

2008-07-19 Thread drewko1
Ok, my final conclusion (i promise) 

Manually adjusting the L and C values of the ATU DOES have an effect
on BCB reception (had my RF gain turned down before, so seemed like
there was no difference). Maximum L (17.35 pH) gives maximum received
signal strength on a short antenna, as expected. 

However, you can't adjust CA and CT independently. And checking all of
my pretuned bands the values for CA and CT on any given band are
equivalent (which seems odd). Furthermore, merely selecting between CA
and CT with the ANT button while in LCSet mode has an effect on the
received signal-- a couple of s-units difference between the two is
what I noticed. (But I don't think it is the antenna relay being
switched, as mentioned before.)

What I want to know is, are the displayed values for CA and CT
correct, and can they be adjusted independently of each other?

BTW, I am using F/W ver 2.13.

Thanks,

Vic and Drew,

The ATU in the K3 is a low-pass L design which has a series inductance and
*either* an input (Ct) *or* output (Ca) shunting capacitance.  There is only
one capacitance in this desigh, not two.  The single capacitance is switched
between the input (Ct side - transceiver) or output (Ca side - antenna) of
the inductance.  So, when you are in CONFIG:KAT3 -- LCSET -- ATU TUNE,
tapping ANT switches the capacitance between the input and output of the
inductance.  You can hear the relay switch when tapping ANT and sometimes
hear a distinct difference in the received signal.

In general the capacitance will need to be on the input (Ct) side when the
antenna impedance is below 50 ohms and on the output side when the antenna
impedance is greater than 50 ohm.

You can look at the circuit design in the K3 schematics (documentation page
on the web) if you would  like to get a more detailed understanding.  Or,
you could also look at a program like TLW (transmission line wizard) that
will calculate and show you a picture of the correct values for a low-pass
L ATU with any given values of antenna impedances.

Hope this helps!  73,

Since the recent clarification of Administrator Michael D. Griffin's

Re: [Elecraft] K3 Scan Rate

2008-07-09 Thread drewko1
The RATE button gives you a choice of scan rates but it would be nice
if there was a wider range of scan speeds available. Depending on how
much band you want to cover, how crowded it is and what you're
scanning for, you might want anything from very slow to very fast,
with a lot of variability in between. If you could adjust the scan
rate interactively while scanning, that would be super.

Also would be nice if the dwell time was user selectable (i.e., the
amount of time a scan will pause on an active freq before resuming the
scan). 

I don't think many people use the scanner on HF but I have found it
very handy on the K2 looking for CW signals. Haven't tried it on the
K3 yet, but from the manual description it looks pretty much the same.

Dahs are actually twice the length of dits, I think. Or technically,
the dah period is twice the dit period (i.e., a dah sound plus its
space is equal to two dit sounds and their spaces).

I measured the dahs instead of dits because I don't have a keyer; just
pluged my mono straight key plug into the paddle jack and it gives
dahs. 

I measured the period by averaging over five dah periods with the K3
readout set at 22 wpm and 21 wpm, giving periods of  0.207s and
0.219s, as mentioned. I measured the sidetone at the headphone jack
using audio waveform software.

Morse code legends for button pushes would probably be very useful to
those who have vision problems (I don't). 

But ergonomics counts for an awful lot, too. Especially during long
sessions at the rig. Being able to access functions without
consciously searching for the buttons and then having to shift focus
to the display to see what state those buttons are in... this
admittedly tiny effort does add up over time. So, I'd place
audible/Morse feedback somehat above coolness factor, if not exactly
top priority.

Also, compared to the K2, the K3 buttons don't have the same
satisfactory tactile snap. Even a simple short tone upon button push
would add a lot to the operating experience I believe. I'm looking
forward to this feature but no, it isn't a top priority.

Why stop at a chirp? Elecraft could make a voice synthesis module, like the
ones in car sat-nav equipment. Whenever you key down, a user-selectable
voice (Arnie Schwarzenegger? Margaret Thatcher?) could say Warning. Test
mode selected.

Other warnings could save the user from making potentially expensive or
simply embarrasing mistakes, like: Warning: High SWR detected. or Voice
modes not permitted in the CW sub-band. It could even offer helpful pile-up
breaking tips if it detects that you have been calling for several minutes
on the same frequency.

Re: [Elecraft] K3 operating scripts vs. operating tips

2008-06-29 Thread drewko1
I think MODE should be the foundation upon which the various
interconnected functions are built. 

I would like to see a mode-specific band switch scheme. For example,
if you are in CW, switching bands will recall the frequency, filter
settings, etc. which you last used in CW; further taps on the BAND
buttons will take you through all your last used CW settings on the
different bands. If you switch to AM it would recall the last used AM
freqs (different from the CW settings), filter, RX eq, etc. Same for
SSB, etc. 

This could also be the basis for sensible general coverage band
switching as well.

Some details would have to be worked out but a few simple rules
would make this MODE-based scheme workable and convenient, I believe.
What programming resources, memory, etc. it would require, I have no
idea... But that's my suggestion.

Ron,

I like that!  I set CW mode, and CW mode stays, etc.

Covering just a few more related comments:
I usually can remember what I have set on or off over a short period, 
but with all the combinations and 'magic' that are possible with the K3 
and other radios that make use of memories, I have to remember what I 
have set into those memories, and because of that, I usually do not use 
memories.

Some asked for a radio that had knobs and buttons, others asked for a 
radio that can do 'magic' in a contest situation, and we now have a 
radio that can do both, but the UI is growing more complex.

You are correct, the more function coupling there is to a single button 
tap or press, the more difficult it is to learn to use the radio.  IMHO, 
I would rather press 2 buttons in sequence for a combined function than 
to have the radio attempt to do it for me.

Radios today are getting complex and that complexity shows through in 
the User Interface - it has to be learned.  I liken it to learning the 
controls of a 747 (but I am just guessing, I have not examined the 
controls of a 747).  The 'decoupling' you suggest might bring it down to 
the level of the controls on a common automobile which should be more 
intuitive for the average operator.

 I realize that the complex interconnected functions that have been evolved

 But for myself, I'd rather not have the radio second-guess me using some

Re: [Elecraft] K3: Choosing which filters to buy

2008-06-25 Thread drewko1
Remember that whatever 'roofing' filters you get you will still have
DSP filtering down to 50 Hz. 

My K3 will be used almost exclusively for CW and  SWL/AM bcst. So I
got the 13 KHz filter for AM reception, along with the 500 Hz filter
and the stock 2.7. 

Maybe I'll get the 200 or 250 at some point, figuring that for CW in
those rare instances when the 500 5-pole isn't good enough the
narrower filter will save the day.

Re: [Elecraft] K3 noise blanker sure does the job.

2008-06-24 Thread drewko1
You can try switching off a suspected street lamp by beaming its
photocell with a laser pointer. The photocell is located on top of the
lamp housing. It is directional, usually oriented toward the north
(but not always) so you would have to spot it with the laser from this
particular direction. 

You could go around the neighborhood with a portable radio and a laser
pointer, trying each lamp. Or set up a recorder at your rig, tuned to
WWV time signals, and log the times when you switch off particular
streetlamps. Having a tripod for the laser pointer might help. A green
laser will make a nice beam which you can see, not just a spot.

How you explain your activities to the cops when they pick you up is
another story...

Lyle KK7P

I'm looking forward to trying that on a crowded band. So far since
I've gotten my K3, every time I turn the rig on band conditions are
poor and the signals have been few and far between.

For those who asked, here are my RXeq settings. I'm not sure how much
use they will be to others. The settings will be dependent on band
conditions, speakers/headphones, hearing acuity and personal
preference. I expect to be tweaking these settings fairly often. 

Using a 600 Hz offset/sidetone and a 2.5 KHz bandwidth, here are my
present numbers on a noisy 40m daytime band:

50  +16
100+16
200+16
400+10
800+9
1600   +1
2400   -6
3200   -6

I did these by ear without regard to the numbers. The 3200 band
setting has no effect since the CW b/w only goes to 2.8 KHz. At least,
I can't hear any effect . I just dialed in the  minus-6 number for it
to be consistent.

I adjusted these with NR off, figuring they would allow
less-aggressive NR when I do use it.

The low bands are cranked all the way up. They don't contribute any
noise that I can hear and I want to be able to hear off-freq signals
at these low tones.

The high bands are cut just enough to remove the most irritating
portion of the noise. But again, not too much as I want to be able to
hear the off freq signals. 

Except for the 400 and 800 bands these setting can probably remain
unchanged. But these two I expect to tweak pretty often (my sidetone
is 600 Hz). I'll just tweak them on a signal for the best noise margin
as I hear it.

I wouldn't mind having more than 8 bands of eq up to 3200 Hz. Of
couse, only eight bars can fit on the display at one time. Maybe they
could scroll right and left if bands 9 through 12 were added? But
really, 8 bands works well enough.

Once the eq settings are dialed it would be nice to be able to switch
back and forth to a flat setting for a quick comparison. Pushing the
CLR button restores to flat but then you lose your settings and have
to dial them all in again. I wonder if CLR could be made to toggle
between your own settings and flat instead of wiping them out?

Re: [Elecraft] K3 RX eq for CW

2008-06-22 Thread drewko1
Yes, thanks to Steve. Fooling around with Rx eq I used his settings as
a starting point and adjusted as follows: 

I cut some of the higher bands as he did in order to reduce noise. But
not too much, in order to hear signals farther off freq I generally
use a pretty wide xfil to hear more of the adjacent signals. (There
aren't too many of them out there lately.)

I also boosted the low bands because they don't add much noise and
will make it easier to hear those who call far off-frequency on the
high side (i.e., lower tone). My sidetone is 600 Hz and I can hear
off-freq signals up to about 500 Hz lower in tone (higher on the
dial).

So RX equalization is most useful to those of us who like a wide CW
filter b/w. 

Yes, Bud, it would be very nice if the RX eq was mode specific.

The 5 khz tuning steps are awfully touchy, even at the lowest VFO rate

Thanks, Don. That is a big improvement. I did suspect that I was

Use the fine/coarse controls in conjunction with the RATE button.  Tap
the RATE button until the 100 Hz digit place blinks and that allows you
to easily tune in 50 Hz steps which is 5 kHz per revolution with a 100
count setting.  That is certainly good enough for me.

It takes a lot of manual reading along with some experimenting with the
K3 to discover all its flexibility - so for those who have not yet done
so, 'Read The Fine Manual'.  Fortunately, the default setting result in
a quite workable radio, so it is usable after only skimming the manual,

[Elecraft] K3 Suggestion - Spot/Pitch

2008-06-17 Thread drewko1
FWIW, another suggestion for the pile...

While tuning some weak CW with my new K3 it occurred to me that the
ability to vary the pitch of received signals might be userful. Under
marginal conditions this might prove handy in optimizing a weak
signal.

Of course, we have the PITCH control-- but when it is activated the
sidetone comes on and the received audio is cut off. I suggest that
the sidetone should be absent and the received audio should be heard
when PITCH is activated. Then by varying VFOB one can directly alter
the pitch of the signal(s).

Now, since VFOB has no function while SPOT is on, perhaps it could be
used to vary the sidetone pitch.

In short... PITCH would allow you to directly vary the pitch of
received signals while listening to them, while SPOT would allow you
to vary the pitch of the sidetone.

[Elecraft] K3 #1029 Build

2008-06-15 Thread drewko1
The build went fine except for mounting the speaker. I think the
supplied fiber and toothed lock washers are too small in diameter for
the width of the speaker mounting slots. It's pretty difficult to keep
them from slipping through the slots, and then the screws go crooked..
I finally gave up and just used larger fiber washers.

I also updated the firmware, no problem. Used a straight serial
connection to the PC. But I'm wondering, would it be okay to plug in
the serial cable while the K3 and PC are powered up?

Here's an assembly hint... Use a magnetized screwdriver. It is much,
much more convenient! (The only screws that aren't magnetic are the
display window screws.)

I assume people don't generally check out all the modes on a

to choose a mode then jump to other bands while in the same mode.

As I mentioned in another post, you could have pretty much the same

the buttons would step through one set of freqs/filter settings; in

For example, in CW mode the frequencies/settings recalled by cycling

Re: [Elecraft] K3 Band changing...Devils Advocate...

I don't have a K3 yet but I'm happy with the Band+ and Band- buttons
on my K2. I pretty much know how many pushes I'll need to get from one
band to another, usually only one or two away. 

Anyhow, the display changes instantly with each button push before the
relays get a chance to switch, so you can quickly step through
multiple bands, watching the display without tripping the relays,
until your target band is reached. For the ten or so ham bands we have
this seems like a reasonable way of getting around. 

I don't know that I'd want ten or twelve extra buttons for this. That
just doesn't seem any more convenient to me. In fact, it is less
convenient. (But then I am a bug and straight key op so pushing a
switch many hundreds of times in sequence is not a big deal to me,
haha!) 

I never have to look at the Band+/Band- buttons; I know where they are
by touch and can just focus on the display. I see that the K3 also has
them in the same location: top left corner. That is ideal as far as
I'm concerned.

Now, getting around the non-ham bands is a different story. I'm not
too crazy about direct frequency entry. Would prefer to just spin a
knob to increment or decrement the frequency in 1-Mhz steps, maybe
five 1-MHz steps per each full turn of the knob.

I understand there is some problem with going between ham bands and
non ham frequencies. I expect this will get straightened out at some
point.

they are performing, then memorize the meaning of the buttons, and call up a
particular (and memorized) band with a single button. 

And this would be more convenient than cycling through the band select
buttons, presumably because you are forced to cycle through bands you may
not need to at this point in your operation.

Am I getting this right? I apologize for the bandwidth - I'm just trying to
get educated.

Re: [Elecraft] Elecraft K3 Wait and Wait and Wait!

2008-05-21 Thread drewko1
Hello Ed,

Yes, some people would prefer to wait till they can buy one without
waiting...

For myself, I ordered one before I'd decided whether or not to
actually buy one-- so it is really Elecraft who is waiting for me. I
think they will be sending me an email any day now asking for my
decision. I imagine they are probably getting pretty nervous about my
final intentions by now.

There is a lot of psychology in all this.

Hello Drew, AF2Z

I plunked down over $1300 for a deposit on my K3, but after waiting five
months and then calling Elecraft they told me to wait another three
months. That was a total wait of 8-months! At the five-month point I
told Elecraft to cancel the order and send my money back.
I then went out and bought an Icom 703+ and just love this little radio.
It's no K3, but for less than $700 it's worth the money.

I still plan to buy a K3, but I WILL NOT WAIT MONTHS to receive it.
Elecraft doesn't have their act together concerning the K3. This is from
an op who built a K1, K2 and a KX1. I'm VERY disappointed in Elecraft
selling the K3 before they were geared up for production.

When Elecraft has a K3 ON-THE-SHELF I might buy one.

Re: [Elecraft] K3 BETA FIRMWARE RELEASE -- MCU rev 1.94

2008-05-14 Thread drewko1
When tuning by ear using a wide bandwidth filter, I have found that it
is easier if you go from the low tone side to high instead of high to
low. I think the higher octave(s) can sometimes confuse you when you
go from high to low. 

Yes, it is pretty easy to get within 10 or 20 hz by ear. For most any
CW work I also would think you'd be ok if you could only manage to get
within 100 hz. I bet lots of people could be able to do it with some
practice.

Still, the auto-spot is a neat feature and i'm looking forward to

Guys,

There is another way to solve the CW spot problem.

It's called get on the air and work CW.  You will quickly develop the skill
of zero beating by ear.
You will find that most CW ops don't use any zero beating gizmo.  Much
faster and easier to do it by ear.

Another thing.  Narrow filter passbands help.  If you're trying to zero beat
a CW signal with a 2.8KHz filter, it can be an exercise in futiltiy.   And
if a human can't do it,  don't expect some computerized gizmo to do it well
either.

Practically speaking,  if you've dialed in a 200- 400Hz CW bandwidth and you
peak the signal in the passband,  your going to be at most 100Hz off.   That
is really plenty good enough for most situations.

How accurate can zero beating by ear be?   The data points I have are from
RTTY.   My display indicator reads out deviation from zero  in 5 Hz
increments.I can usually get within 10-20 Hz by ear!   I'm going to
assume the CW accuracy is similar.

Re: [Elecraft] K3 Band switch

2008-05-08 Thread drewko1
I originally suggested the [VFO dial + HOLD COARSE] combination to do
the 1 MHz stepping because I thought it might be easy to do with just
one hand. Not having a K3 in front of me yet, I don't know if that is
so. Anyhow, in general I prefer knob turning to button pushing, given
a choice (analog vs digital, so to speak...)

Ok, what success do you expect in hitting 10.101...  

Say you're on 6.035: You hold COARSE while turning the VFO; the
display changes to 7.035, then 8.035, then 9.035, then 10.035 (about
half a turn in all, at the 5 MHZ/turn rate); you then let up on the
COARSE button and tune the VFO normally to 10.101 where, having
entered the 30m band limits, your settings for this band are restored.

The Band+ and Band- are fine for ham band switching. But for general
coverage navigation a real band switch, as above, would be preferable.

Now, you have complained about having to button-push through every
intermediate band to get to a desired ham band. Could this be
alleviated somewhat using the VFO knob as a ham band only switch? Say,
by holding the FINE button you could step through the ham bands using
the VFO knob, perhaps more conveniently than PUSH PUSH PUSH..., In
other words, map the ham bands to VFO knob rotation while the FINE
button is being held.

Anyhow, these are just suggestions, not necessarily feature requests.
My only request is to get my K3 (few more weeks!)

What is really needed is one button press to get to the band you want.
Two to six button presses alone or in combo with knob twisting  simply 
isn't acceptable.  
Standing on your head while twisting a knob behind one's back isn't  either.

I miss FORTH [sigh]... 

But back to radios... I wonder if it would be useful to implement a
Very-Coarse tuning rate, say 5 MHz per full turn of the VFO knob.
That would be your band switch.

With such a rate you could quickly get to any band, ham or SWL or
whatever. However, if you should select a ham band with this coarse
tune VFO, it would automatically recall your previous settings for
that band (same as the Band buttons work)

It could be accessed by holding Coarse while turning the VFO knob.
Perhaps this could be managed with one hand?

No, I meant a tuning rate of 5 MHz per full turn of the VFO knob...
but it WOULD increment the frequency readout in 1 MHz steps, as you
suggest. 

5 MHz per one full turn would, for instance, let you go from 7.0xx MHz
to 15.1xx MHz in about one and a half turns of the VFO knob, acting
more like a band switch than a VFO. Perhaps 10 MHz per turn would be
even better. The current Coarse Tune rate (1 or 2 MHz?) is not coarse
enough to act as a band switch.

macros, specific to different software application, to make them work

I wonder if at some point, if the K3 UI should indeed become too

I like your suggestion.  After all the prime focus of the K3 design is
amateur band, CW,SSB, and digital modes. Having high performance for these
modes is its selling point.  Asking it to do everything on all frequencies
detracts from efforts to optimize its primary functions.

In almost 50 years,  I've heard maybe 1 amateur FM station operating.  
Yeah, there may be a few more but it hardly constitutes a majority mode. 
Are there really so many ham AM ops? 

Sure people are free to buy anything they want.   Their choice.  However,
what they do buy may not be optimum for their needs.

Maybe it would be useful to be able to transmit-lock one of the

Another idea: provide an audible enunciator whenever A/B is pressed.
For example: a single beep for A and a double beep for B (or
alternatively, a high tone beep for A and a low tone for B). This tone
enunciator would tell you instantly which vfo you have selected and
would quickly become ingrained in your operating habits. (Better yet::
di-dah for A and dah-di-di-dit for B would be way cool! Perhaps
there are other rig functions that could benefit from Morse code
enunciators?)

As for Split, I wouldn't mind having a periodic audio warning to
remind me that it is on; perhaps some low-profile chime every
x-seconds with user-selectable volume, tone and beep rate. (But then
again, I am a cw op so not worried about it getting out over the

[Elecraft] K3 VFO slave mode suggestion

2008-03-01 Thread drewko1
Sorry if I missed this in the K3 manual

I have sometimes thought it would be useful to slave the B VFO  to the
A VFO. For example, changing VFO A would also change B an equal
amount; but changing B would have no effect on A. 

I think it would be handy to operate split this way on the K3, with
its two VFO knobs, during contests and such. I guess that is what RIT
and XIT are for but they have always seemed a bit clumsy to me on the
K2 (don't have a K3 yet).

Anyhow, if this doesn't exist on the K3 I'd like to suggest it.

one sideband through the 6 khz filter. I wonder if the performance

the wide filter. Oh, well, still have a couple of months to decide...

Another approach for an RF ground is to use your connection to the ground

it is frequency-sensitive: it requires readjustment for every band. And,
because the circuit involves a capacitor in series with the coil, it is not
a d-c ground if that's what you are looking for. But it can produce a good

An automatic ground tuner might be nice-- a GTU, i guess you would

Re: [Elecraft] Wrong Filter Question - 8 pole vs. 5 Pole Filters

2008-02-04 Thread drewko1
I'm guessing that I wouldn't be able to tell the difference, like
monster cable for the stereo. Will there ever be an instance when I
will say, Boy, if only i had an 8 pole filter; I might have snagged
that rare DX station! I doubt it.

Actually, if it had been a choice between 8 and 5 in a 500 Hz filter,
I might have chosen the 8. But I don't want a 400 Hz filter however
many poles it has; I want 500 Hz. This has to do with the fact that in
a hypershphere of very high dimensionality nearly all of the volume
lies very close to the surface. Just kidding. The filter graphs mean
next to nothing to me.

I guess when it comes time to sell the rig the 8-pole guys will have
an advantage over us filter ignoramuses and cheapskates. Anyhow, the
price difference between the is now $40 for me according to the order
summary.

Re: [Elecraft] Is the K3 for non-contesters?

2008-02-02 Thread drewko1
Steve,

I will be using the K3 for pretty much only CW and SWL. Perhaps a
little PSK. 

I like some small CW contests, but am not a contester by any means. 

I'll be sticking with the 10 watt version; my K2 has shown that that
is sufficient power for me. Will also only have a very basic filter
set. 

I did order the ATU; the K2 spoiled me with that. My antennas are
endfed wire and attic dipoles.

Too much rig for my limited needs? Maybe, but I'm pretty sure I'll get
my money's worth in enjoyment.

The rig's extensive menus, its Cadillac-like fit and finish, and firmware

I operate lots of CW with a small fleet of two K2s and a KX1 that are all 
excellent performers.  Occasional SSB and PSK QSOs are also very enjoyable.

I'm just curious about whether the K3's capabilities and performance are as 
appealing to others like me (non-contesters) as they obviously are to 
contesters.  I'm a great fan of CW and have been trying hard to get my code 
speed up to a consistent 20-25wpm for a long time.

One solution is to wire in a speaker/headphone toggle switch when you

That will eliminate wear on the jack. (It's also lot more convenient

The defective contact lies at the rear pins of the jack, which you can
easily parallel with one pole of the switch. But you will also want to
switch the ground (i.e., sleeve) terminal of the jack with the other
pole, opposite  throw (a DPDT switch). If you don't switch the
ground/sleeve line the headphones will end up being in parallel with
the speaker when it is selected. 

The ground/sleeve terminal lies on the board side of the jack so you
will have to remove the jack to get to it; might as well replace it
with a good jack.  

Of course, you could leave the defective jack in place, cut the ground
circuit trace and solder tack the switch across it. But that's no
easier than just replacing the jack with a good one, and no messing
with the traces.

Referring to my notes, the switch I used was p/n: 8011 from
Web-tronics. It is a DPDT (on-x-on) miniature size. Fits neatly in the
transverter hole beneath the speaker jack.

it is anyway: 

How about a keyer memory which would work with a straight key. It

transmitter with this recorded fist. Is this something that would be

The advantage is that straight key  bug operators could program CQ

But apart from the durability issue, the headphone/speaker switch is

Doesn't the K3 have a 1/4 jack (vs 1/8)? That alone will make it a

[Elecraft] K3 Filter advice...

2007-12-26 Thread drewko1
I'm wondering what minimum complement of filters would work for me in
a K3. I am only interested in general coverage reception of SWBC
stations, plus operating CW. I am a little unlclear about what filter
would be required for AM (reception only), with the KBPF3 option.

For CW I generally prefer a wide filter (my K2 is set at 2.0 kHz most
of the time). I suppose I would want a narrower filter as well but
can't decide whether 500/400 or 250/200. 

Does a 2.1 kHz + 200 Hz filter pair seem like a useful combo for CW?

Finally, I don't have a clue what noticeable difference there would be
between a 200/5-pole and a 250/8-pole. If the difference is really
subtle or limited to very occasional use I suppose I'd go for the
cheaper one.

We know that low pitches are better for the brain to separate two 
different pitches (a signal in QRM), and we also know that very high 
speed CW operators like a higher pitch because it is easier to discern 
the code elements.  If you belong to either group, your choice is 
obvious, but I believe for most, the compromise using the Elecraft

I was thinking of doing a bunch of filter alignments at sidetone
pitches 50 Hz apart, just to tabulate the filter settings. If you

you want to change sidetone pitch.  It's only 4 three-digit DAC

between rigs. I know it varies between bands. I can play with the K2 RIT
value and get at least +/- 50 Hz or more of variation from my 400 Hz
preference. Last night I readjusted the KAF2 pots and got the response more
centered around 400 Hz. It had been centered a little lower.

Last night I was working a CW station on 30 meters just in my noise level.
Usually I have to listen a little lower in pitch, but this time it helped to
listen a little higher. The band conditions seem to dictate the best pitch.

That said, I wonder how to best choose a pitch. I've thought of increasing
the pitch up to 420 or even 450 Hz. But I won't be able to return to 400 Hz
without running CAL FIL again, not a fast process. I definitely don't want
to go above 500 Hz. The 600 Hz default is very fatiguing to me and actually
piercing.

Again I know this is a personal thing. It really would be neat if the K2
firmware could be modified to accommodate several banks of filter settings
for different needs, such as CW pitches.

 I like very low pitch (240-270 Hz) for extremely weak signals in white

On a wide quiet band, I will even go to 500 Hz pitch with a very wide
bandwidth to catch callers up to 500 Hz off-frequency (BTW Japanese
stations are much worse than EU for calling off-frequency).


Wow! I find this amazing. I have just never used a pitch that low. I
will have to try it I guess. Seems like I am way higher than normal at
800 Hz. I like a wide filter most of the time also: 2 KHz  1 KHz most
of the time, seldom dropping to 0.5 or 0.2.

Is a low pitch better for weak signals? I guess I never knew that.

This is the way our BSP (biological signal processor) handles it.

Yes, this is very good advice.

Ok, that makes sense. 

Now what about weak signals in noise (no QRM): any idea which pitch is
better there? 

And I wonder about keying speed (element length): a shorter element
must carry better at a higher pitch I would think.

Of course, it doesn't matter much if your own ears have a problem with
the theoretical best pitch, i suppose.

Re: [Elecraft] K2 headphone jack

While some say the jack fails due to downward pressure and others say it 
fails due to repetitn, lately some think that the switch in the jack is 
damaged by excessive heat during soldering, so I tried to solder it as 
quickly as I could this last time, and also I installed a fixed-level 
audio out board for digital modes, so that I wasn't tempted to plug in 
the headphone jack when I didn't really need to.


There is a contact that slides across the three rear pins of the jack.
If soldering is the problem, it is those three pins to watch out for.
This contact is definitely the weak point of the switch.

See my earlier post to this forum (Lost speaker audio in K2)
regarding installation of a headphone/speaker switch; then you can
leave the headphones plugged in all the time and just use the switch.
In any case, the switch is a lot more convenient. (Seems like I was
forever hitting the NB button when trying to get the plug out...)

If you want to add a switch the time to do it is while replacing the
jack becuase you have to bend one of the jack pins out of the way
before installing it.

Here are comments I sent to someone who asked me about it:

 The switch I used was p/n: 8011 from Web-tronics. It is a DPDT
 (on-x-on) miniature size. I bought it along with their budget
 soldering station-- a nice unit.

 http://www.web-tronics.com/index.html

 I'm sure you can find similiar switches at Mouser:

 The mini-size switch mounts securely with the supplied hardware in the
 rig's Transverter hole, below the speaker jack. I figured that if I
 ever get a transverter I'll worry about moving it then. If you're
 going to drill your own hole for the switch you might consider getting
 a sub-mini switch. As it is, mine doesn't interfere with my K2 options
 (antenna tuner  noise blanker).

 One pole of the switch is wired to the ground pin (center, forward) of
 the jack (bent flat, as mentioned), and to its mating pad on the
 circuit trace.

 The other pole (and opposite throw) is wired across two of the three
 rear pins on the jack body-- I can't remember which two at the moment.
 Actually, it is not wired directly to the pins but tack soldered to
 their circuit pads.

 I used a round 4-cond cable, routed as mentioned. But you might want
 to try flat ribbon cable instead. Maybe that will be able to sqeeze
 past the board to the rear compartment; you better check first to make
 sure there is enough clearance.

 Now, I think all of that is correct, but If any questions, please ask.


As for which of the three rear jack pins are wired to one of the
switch poles (mentioned above): With the jack flat on the table, hole
facing you, pins pointing up, it's the rear-right pair of pins.

Re: [Elecraft] Lost speaker audio in K2

2007-09-15 Thread drewko1
My headphone jack failed in short order. I am constantly jumping back
and forth between headphones  speaker, so the mini-jacks don't stand
a chance with me for very long.

When I got a new jack from Elecraft I decided to add a
headphone/speaker switch to the back panel; now I leave the headphones
plugged in all the time and use the switch to go back and forth. This
is a wonderful mod. It fixed the one truly annoying feature of the K2
(to me, at least).

When I replaced the jack I bent the center front (ground) conductor
flat; one pair of switch contacts are soldered to this contact and the
now vacant PCB trace beneath it (with a sliver of fishpaper between
switch and board for insulation); the other pair to the back contacts
of the jack... well, you can figure it out from the circuit.  I routed
the 4-conductor cable along the front of the control board, toward the
on/off switch; there is a space there where the round cable can get
past the board.

Anyhow, it is so conveniet to be able to switch the audio from
headphone to speaker as often as I want, without having to fiddle with
the tiny ill-fitting plug, and always wondering when the jack is going
to die again.

Next project: fixed level audio output for recording my QSOs.

I just lost the speaker audio in my K2/100, but still have audio through the

Looking at the schematics, it looks like the headphone jack could be faulty.
The speaker audio runs through the headphone jack and bypasses the speaker
when a headphone is plugged in. It looks like the headphone isn't returning
the audio back to the speaker line when the headphone plug is removed.
 
Has anyone else encountered this problem?

Re: [Elecraft] K2 speaker jack question

2007-06-02 Thread drewko1
I think I'm going to install a speaker/headphone switch on the back
panel so I can just leave the headphones plugged in all the time. Then
switch headphones  speaker as needed. 

Apart from the mini-plug being relatively fragile, it's also annoying
to plug  unplug. It doesn't go very easily and I often hit the menu
button while trying to work it. I have to say, it's the only really
annoying feature I've found on the K2.

Re: [Elecraft] K2 Improvement Ideas

2007-05-08 Thread drewko1
I had been thinking about having a filter parameter memory card, where
you could store the bandwidth/bfo figures from a number of different
alignments and instantly recall and load them. Say you had five banks,
you could have four bandwidths at each of five different
sidetone/offsets. But I don't know enough about this to know why even
this limited option (let alone continuously tracking filters) wouldn't
be practical.

On a occasions, especially when the filter is set narrow and the signal is

particular sidetone frequency.   Being able to change the CW sidetone can
again un-mask the signal.
