Re: [Elecraft] FW 3.06 - 6m missing

Mine is OK, have you checked 6m isn't also mapped out?

K3/100 #80 f/w 3.06
===
Loaded FW 3.06 yesterday. All OK except

This morning I cycled through the bands and found 6 meters missing.
I am sure that 6m is mapped in. Checked that with K3-EZ and in the
config.

What happens is this:
Cycle up through the different bands and after the 10m band comes 6m? No
band noise, not even with pre-amp on.
AND the display says 30.000.00
Touching the VFO changes the display to 29.999.99 and the band noise
comes in. So probably I'm back at 10m.

Another thing I tried was this:
Switch to config and go to the band mapping.
Cycle through the bands until you reach 6m, and yes it is mapped in.
Leave config.
Display is at 30.000.00 and K3 reacts the same as mentioned above.

Only band I have mapped out is 60m.

Am I the only one with this problem? Or maybe I've missed something.

Re: [Elecraft] totally OT, except to the extent that it's QRP: LED lamps

2009-04-04 Thread David Cutter
Perhaps the time is now right to replace domestic lighting circuits with 12V 
supply, then the cost of the fitments will come down, ie no need for 
110/240V conversion to low dc for the leds.  Safer, cheaper, more reliable, 
less raw materials.  At those power levels, you could probably keep the 
original house wiring and just fit a 12V transformer/rectifier.  Easier to 
use alternative power sources, too.

Be nice if we had your prices over here.

Subject: [Elecraft] totally OT, except to the extent that it's QRP: LED

I just replaced four gas-guzzling incandescent lamps in my dining room
 chandelier with four LED lamps that screw into the same bases. Went
 from 240 watts to 6 watts, total.

 The usual complaint about LED lamps is the cost. But prices are coming
 down fast: these were only about $4 each at Costco. Each contains 21
 white LEDs, and they basically last forever, which means I won't
 constantly be replacing lamps in this fixture.

 If the world converts to LED lighting, we won't need to build any more
 power plants, and we can all use KW amps guilt-free :)

Re: [Elecraft] K2: KPA 100 Capacitor Specification?

2009-04-04 Thread Geoffrey Mackenzie-Kennedy
John,

If the voltage rating of these relay coil bypass caps is somehow being 
exceeded in your shipboard installation causing the caps to fail, and if you 
cannot find suitable higher DC voltage rated leaded replacements, you might 
like to consider using SMD (chip) capacitors instead.

AVX include in their product line of multilayer ceramic SMD capacitors for 
low frequency use, as opposed to microwave rated devices, .01uF  100 VDC 
caps in both 0805 and 1206 sizes, and 0.015 uF caps rated at 500 and 600 VDC 
in 1206 packages.

I have no financial interest in AVX, but do use their microwave rated 
capacitors.

Geoff
GM4ESD


Don Wilhelm wrote on Friday, April 03, 2009 at 3:29 PM.

 John,

 I have never found one of those caps shorted, and I believe the DC
 rating on them is 50 volts, so they should have an adequate safety
 margin since they are used in a 12 volt DC circuit.
 I have trouble imagining a condition that would cause them to fail, but
 then I recall that your 'shipboard' operation is unusual and may
 introduce 'perils' that I cannot imagine.
 There would be no harm in replacing those capacitors with 100 volt caps
 *if* you can get them to fit physically.  You may have to solder them
 flat against the bottom of the board.  The other problem is that 100
 volt caps may be difficult to procure with 0.1 inch lead spacing and you
 may have to get creative to substitute caps with 0.2 inch lead spacing.

No err-msgs
Sub-RX in config-menu set to *yes, installed*

no receive, only noise like there is no antenna connected,
noise characteristics change with selected filter (Bandwith/shift)

Faint signals from *strong* stations.

Signals from my K2 sound ok when i transmit into a dummy load and
receive them with the K3 sub-rx.

So the sub-rx is not dead, but deaf.

The K3 has sub-rx, KXV3, equal filters ssb/cw on both rx's , *no* KAT3.

Where to begin the troubleshooting?

[Elecraft] OT: Home Energy Audit Website

2009-04-04 Thread Bill W4ZV

Wayne's comments about energy savings prompts me to share the following website 
with everyone.  This is a **very** comprehensive model developed by Lawrence 
Berkeley National Laboratory.  I recently discovered it while investigating 
potential savings to convert my present air exchange heat pump to a ground 
source heat pump.  In my case, the model very accurately (5% error) predicted 
our total annual household energy usage compared to our actual electric bill 
(13,288 kWh per year total for all energy).  The model provides estimated 
savings and ROI for improving energy usage options (one of which is switching 
to more efficient lighting as Wayne did).   In my case, out total heating and 
cooling usage was already so low (~$500 per year) that conversion from a 
reasonably efficient air source heat pump (SEER 13.0) to ground source was not 
justified on an ROI basis.

http://hes.lbl.gov/

While the heat pump conversion was not economically justifiable, I did discover 
one startling fact.  I've been in the habit of leaving the tower computer in my 
shack on continuously (without going into sleep mode).   Assuming 200 W/hr 
consumption, this amounts to 1,752 kWh per year ($185 per year at our $0.106 
per kWh rate) which is a staggering 13% of my total energy bill!  Needless to 
say I'm no longer leaving that computer on.

If you carefully enter the data for your household into the model above, you 
may discover some cost effective alternatives for saving energy...and money.  
It takes awhile to enter all the data accurately but I found it well worthwhile.

73,  Bill  W4ZV

[Elecraft] Inductive relay kick

2009-04-04 Thread Carl , WCØV
Don, seriously disagree about the magnitude of the kick. For years I taught a 
course on industrial installations and demo'ed the kick issue by soldering 
two bare wire to the coil of a small Potter and Brumfield ice cube 12 vdc 
relay. I would pick the biggest guy in the class to hold the wires while I 
touched them to a nine-volt transistor radio battery. And then watch as he 
would throw the relay across the room. A reverse diode would vastly reduce the 
effect.

Well, I got yelled at and was told Hey, Stupid (and stupid wasn't the word 
they used)! Put that on a storage scope to see what you're messing with. The 
scope showed a spike of 450 vdc! The diode reduced it to less than 75 vdc. 

The magnitude is due mainly to the large inductance of the coil, but until some 
measurements are taken, some caution is advised. The inductance of any coil 
inside a K2 or K3 is bound to be much smaller. But the phenomenon is the same.

The problem is still unable to load FPF or DSP firmware. MCU loads fine.
I have used two different computers in an attempt to load the firmware. On
each computer I have used the KUSB and a 9 pin straight thru serial cable.
That doesn't work.
I have reloaded the K3 utility to make sure it is the latest version and
still no luck.
In numerous e mails with Gary we thought trying a new front panel board
might work. Wrong , After installing a new front panel board same problem.
On page 63 of the owners manual if I hold in the shift / Lo knob while
turning on the power I am suppose to see EE INT. All I see is ERR EE2.

The K3 is a nice looking radio and maybe one day it will work but , Right

Re: [Elecraft] K3 external speaker

2009-04-04 Thread Phil LaMarche

I have a choice of two speakers that work very well.  I power the K3 through
a 100 watt amplifier to two book case speakers on the wall, pointed at me.
I also have he Wet Mountain radio's COMSpkr's that are under a 100.00 and
really work well and sound exceptional.

Google West Mountain radio.  I believe they are around 50 bucks.

Re: [Elecraft] K3 external speaker

2009-04-04 Thread Tom Hammond
R:

For me, the best choice was a couple Motorola UNamplified Mobile speakers
from EBay.

I managed to find a matching pair of NEW speakers for $10 + shipping.

You'll want TWO (2) speakers so you can take full advantage of the AFX
features of the K3.

My particular speakers were model HSN4018B, but I have several others
which appear to be identical save for a possibly different color, which
show model HSN4000A.

They work great and I like having the removable mounting mounting bracket
as well.

Note: You could use the AMPLIFIED Motorola mobile speakers as well (lots of
modification info for these on my web site at www.n0ss.net), but you really
don't need the 5W-15W of amplified audio unless you're in a really noisy
location.  Additionally, any time you use an amplified speaker you always
run the chance of getting RFI into the audio lines of the speaker... not a
fun problem to have to find/fix.

Re: [Elecraft] Inductive relay kick

2009-04-04 Thread Jferg977
Carl,
It appears that my K2 is the only one in the universe to have  experienced 
this problem.  We don't really know what caused the problem,  but it may have 
been due to vagrant high-voltage under the heat sync resulting  from unchecked 
ESD.  Since the two failed caps must have been the weak  links in the area, 
replacing the 50 volt type with 100 ought to improve  things.

Don, seriously  disagree about the magnitude of the kick. For years I 
taught a course on  industrial installations and demo'ed the kick issue by 
soldering two bare wire  to the coil of a small Potter and Brumfield ice cube 
12 
vdc relay. I would  pick the biggest guy in the class to hold the wires while I 
touched them to a  nine-volt transistor radio battery. And then watch as he 
would throw the relay  across the room. A reverse diode would vastly reduce the 
effect.

Well, I  got yelled at and was told Hey, Stupid (and stupid wasn't the word 
they used)!  Put that on a storage scope to see what you're messing with. The 
scope showed a  spike of 450 vdc! The diode reduced it to less than 75 vdc. 

The  magnitude is due mainly to the large inductance of the coil, but until 
some  measurements are taken, some caution is advised. The inductance of any 
coil  inside a K2 or K3 is bound to be much smaller. But the phenomenon is the  
same.

Re: [Elecraft] K3: Firmware upgrade harder than construction...Help

I assume you have no regular serial port. Have you tried the adapter with your 
K3 and a control/logging  program like HRD? Some usb to serial adapters are 
quirky.

John N1JM

After 10 months I decided to upgrade my firmware from the original 2.16 
since I just got the KXV3 and KRX3...Frustration!
Have a USB 2.0 to RS232 Serial adapter and have tried it in all my USB 
plugs and in Com ports 1, 2, and 4 which are shown as choices on the K3 
Utility.The computer tells me my driver is correct, I've matched 
9600 baud with the K3 and all I ever get is a K3 not responding on Com 
Ports 1 and 2, and Another app connected to Com port 4.  I'd just 
order the CD, but that would not solve my communication from the 
computer to the K3.  What should I try next?

[Elecraft] K3 FSK mode Newbie question

2009-04-04 Thread Patrick Skerrett
Trying to build an interface for FSK mode on my K3 for use with MMTTY.

When I put the rig into data mode  then select the DATA MD button and 
spin the sub VFO, I see the option for FSK  D mode.

Great, however it also comes up as USB  and REV. For me to decode in 
this mode I have to set MMTTY to Rev mode.

I thought that FSK mode would be LSB. However, I cannot figure out how 
to change FSK  D to use LSB.

Am I just totally confused?

Thanks.

Many / most monaural external speakers have a MONAURAL plug on their cords.
DON'T plug one of these (monaural) plugs into the speaker jack.  It's

another's case.  The IC is -NOT- an easy change!  

Just remember that one audio channel is on the tip and the other is on the
ring of the plug and connect speakers in this manner using -only- a stereo
plug.  My particular trap was forgetting that using a  stereo Y merely
moved the trap six inches away from the jack. (;-)

Re: [Elecraft] K3 external speakers

There is a mod on the website to fix this problem. Check out the K3 
Enhancements and Application Notes page and look for K3 AF OutPut Mod 
Kit. A simple installation of 2 resistors.

 Subject: [Elecraft] K3 external speakers

 The following may well be obvious to most, but I know of at least three K3
 owners who've been caught by plugging mono plugs into the (stereo) speaker
 jack.

 There is a gotcha involved in the use of external speakers with the K3.
 It's addressed indirectly on page 20 of the D2 version of the manual in the
 2nd paragraph under PHONES when it reads ... if you use a stereo plug at
 the external speaker jack  but is easily glossed over by the reader.

 Many / most monaural external speakers have a MONAURAL plug on their cords.
 DON'T plug one of these (monaural) plugs into the speaker jack.  It's
 configured for stereo and the sleeve of the mono plug will short the ring
 portion of the stereo jack and thereby short one channel of audio.  I ...
 along with several others ... have experienced a failure of the audio
 amplifier IC on the front panel board due to one channel being shorted by
 the sleeve of a monaural plug.  It seems to take many hours of operation
 under this condition to cause the IC to fail ... over a year in mine and
 another's case.  The IC is -NOT- an easy change!  

 Just remember that one audio channel is on the tip and the other is on the
 ring of the plug and connect speakers in this manner using -only- a stereo
 plug.  My particular trap was forgetting that using a  stereo Y merely
 moved the trap six inches away from the jack. (;-)

 As others have pointed out, speakers from the two-radio field are good
 choices, and the CB isle at truck stops usually sell nice speakers.  Mine
 are Barjan 320-701's.  Radio Scrap 21-549B's are OK, too.

Re: [Elecraft] K3 external speaker

2009-04-04 Thread Joe Subich, W4TV


The N0SS suggested unamplified Motorola speakers are very good if 
you can find them at a reasonable price.  If you can't ... or 
don't want to go fleamarket shopping there are two other options 
I've found to be very reasonable ... 

Best Buy (www.bestbuy.com) has a pair of 3-way Indoor/Outdoor 
speakers (3 1/2 bookshelf speakers) - Insignia SP3Way - for 
about $30 a pair.  I believe they are WA6HHQ's choice ... 

Best Buy and Radio Shack both carry the Sony 5 1/4 two-way 
bookshelf speakers - Model SSB-1000 - for around $50.00. 
I picked up the Sony pair on sale at the local Radio shack 
for around $25 about a year ago.  

Both the Insignia and Sony are unamplified so there is no issue 
with RFI and no need for external power supplies.  They also 
provide a nice uncolored frequency response compared to most 
of the small communications speakers.

Re: [Elecraft] K3 external speakers

2009-04-04 Thread Ken Kopp
The AF Output mod had been made to (at least) two of  the 
K3's that suffered the audio output IC failure, mine included.

Perhaps the mod only helps and that's why the problem took 
months to come to failure.  My board is slightly scorched, and 
the IC burned up on another board.

The audio IC is robust, so I'm told, but can only stand so much 
for so long.  BTW, headphone audio still works after the output 
IC's failure.

Perhaps I'm not too smart, in that I had / have two speakers, so 
I chose two speakers from the menu. (;-).  Duh!

[Elecraft] k3 external speaker mono v stereo plug

2009-04-04 Thread Doug Turnbull
Ken, 
 Thank you for your warning but I am now wondering if it applies to
later SN K3s.   Mine is number 2574 and sure enough I have been using a
mono-plug but in the Config Menu under SPKRS 1 has been selected.   The
manual indicates a preference for stereo plugs but clearly states, If you
only have a mono plug, set CONFIG:SPKRS to 1 to disable right-channel
audio.   A comment from Elecrafter might be in order to fully clear this
matter up.   In the meantime my external speaker is out until a stereo plug
is wired.   Thank you for the warning.

[Elecraft] [KX1, LDG Z11] Builders For Hire

2009-04-04 Thread Daniel Paul Perez
I was considering building or hiring someone to build a KX-1 30/80.

To help me with making that decision I thought I’d revisit a 4 or 5 year 
old tuner kit I had on the shelf to help sort it out.  I have a 
progressive physical disability that has now brought me to the point 
where it is hard to solder components.  I have, in kit form, a partially 
built LDG Z-11 Automatic Antenna Tuner. It’s two boards, 100 components, 
400 solder joints.  I’ve inserted 60-70 components, wound toroids, 
transformer and soldered about 10-15 capacitors with Kester 2% silver 
solder.  Essentially, I've put it together but can't solder it.

I’ve tried emailing three or four people on the Elecraft “Builders for 
Hire” page but have received emails bounced back as they’re obsolete.  I 
also called the owner of LDG who could/would not offer any assistance 
but suggested the Elecraft reflector.

Is there an Elecraft builder on this listserv who’d be interested in 
finishing out this kit with me?

Best,

Dan, AD1P

Re: [Elecraft] K3 Assembly

2009-04-04 Thread Rick Tavan N6XI
Yeah, band buttons would be nice if the panel were larger. But there is a
good work-around that doesn't require a computer. If you're new here, you
may have missed it. Just use quick-recall memories 0-9. This results in two
taps instead of one (MV, n) but it sets you up with all variables the way
you want them.

I use this mnemonic: Memory 0=160, 1=10, 2=20, 3=30, 4=40, 5=15, 6=60, 7=17,
8=80, 9=12. (That last one isn't really mnemonic.) Some folks go in
frequency sequence. Take the time to set up exactly what you want in both
VFOs on each band. I put my favorite CW freq in VFO A, my favorite SSB freq
in VFO B and set up AGC and DSP parameters just the way I (usually) like
them. It's a breeze once you get it set up.

Doug, others ...

If you -do- have a situation where the audio IC is looking
into a shorted load and still working ... remember, mine
and another ran for months before the audio IC failed.

With your radio turned on, remove the top cover and look 
inside at the extreme left top corner of the board closest 
to the shield.  Note if there is discoloration of the edge of 
the board above the large IC and / or stick your finger in 
and touch the IC.  Sniff the area for the tell-tale smell of
hot glass epoxy circuit board.  If it is like mine you'll test 
your reaction time, as the IC will most likely be far too hot 
to touch.

Jim,

It is better to use the approximate ship date posted on the Elecraft 
website listing of K3 Mods and Enhancements.
There can be a serial number differences between the factory ship K3s 
and the kit versions  - the factory built K3 are at the factory longer 
after the serial number has been assigned, so the ship date is a better 
reference.

OTOH, it is a simple matter to remove the top cover and look at the board.

 I was considering building or hiring someone to build a KX-1 30/80.
 
 To help me with making that decision I thought I’d revisit a 4 or 5 year 
 old tuner kit I had on the shelf to help sort it out. I have a 
 progressive physical disability that has now brought me to the point 
 where it is hard to solder components. I have, in kit form, a partially 
 built LDG Z-11 Automatic Antenna Tuner. It’s two boards, 100 components, 
 400 solder joints. I’ve inserted 60-70 components, wound toroids, 
 transformer and soldered about 10-15 capacitors with Kester 2% silver 
 solder. Essentially, I've put it together but can't solder it.
 
 I’ve tried emailing three or four people on the Elecraft “Builders for 
 Hire” page but have received emails bounced back as they’re obsolete. I 
 also called the owner of LDG who could/would not offer any assistance 
 but suggested the Elecraft reflector.
 
 Is there an Elecraft builder on this listserv who’d be interested in 
 finishing out this kit with me?
 
 Best,
 
 Dan, AD1P

[Elecraft] [k3] Tone/Low Bat indication?

2009-04-04 Thread S Sacco
I was working a station on 40M CW (qsk) this afternoon, and suddenly - and
only for a moment, my K3 got stuck and put a high pitched tone into the
speaker, while at the same time, indication Low Bat (perhaps Low
Batt?).  It then returned to normal operation.

I've experienced this getting stuck thing a few times, but never looked at
the display while it was happening.

I'm running 3.04 right now.

Has anyone seen this behavior?  If so, is there a way to address it?

Thank you  73,

 Yeah, band buttons would be nice if the panel were larger. 
 But there is a good work-around that doesn't require a 
 computer. If you're new here, you may have missed it. Just 
 use quick-recall memories 0-9. This results in two taps 
 instead of one (MV, n) but it sets you up with all 
 variables the way you want them.

All that's necessary is to set MEM 0-9 to Band Sel in 
the configuration menu.  After that, M-V followed by 1 
through 0 will recall the last used frequency/mode on each 
band 160 - 6 (1 = 1.8, 2 = 3.5, 3 = 7, 4 = 10, 5 = 14, 
6 = 18.1, 7 = 21, 8 = 24.9, 9 = 28 and 0 - 50 MHz).

After discovering ... after-the-fact ... the cause of my self-inflicted

[Elecraft] K3 Assembly

Seriously, it's hard to keep up with the rate that Wayne adds new features to 
the radio. I've had a K3 since Jan 2008 and a quick look back at the 
advancement of the firmware is amazing.   

It's not a radio that you learn once, but on the plus side it's all documented.

make your own decisions on that.  See Quick Memories in the manual,

[Elecraft] Elecraft SSB Net Announcement

2009-04-04 Thread Phil and Christina
Hi gang,

The weekly Elecraft SSB net will meet tomorrow (Sunday, 4/5/09) at 1800Z.
We will start at 14.316 MHz, and QSY if needed.  The net control is in
western Oregon, but we will need a good east coast or midwest station to
relay a few west coast signals that may be too close to net control.  See
you there.

[Elecraft] K1 problem

2009-04-04 Thread Michael - VE3MKX
Hi All..   Well  Here is the K1 story

I was going threw the RF section taking  voltage measurements (page 5 of 
trouble shooting) trying to figure out why the rig was deaf.  While doing so, 
silly me, I would say other words but  I hit the nut/bolt assembly left of 
TR-3 on the bottom of the main board with the RF probe.  Then ZAP !! Now the 
rig is dead, it will not on.

Not being a technician... Any thoughts on where to start tying to trouble shoot 
this new mess / problem that I just created? ;)

Any help would be appreciated !

Re: [Elecraft] K1 problem

2009-04-04 Thread Don Wilhelm
Mike,

You probably shorted the diode in the RF Probe first, and that in turn 
grounded the collector of Q6, and that in turn would have placed a 
stress on the 12 volt input.

Did you have a fuse in your power cord?  That would be the first thing 
to check.  Do you have 12 volts or more from the power supply?  If so, 
is there voltage at the coaxial power plug? Then how about at the 
cathode of D16?

If you have voltage (12 to 14 volts) at the places above, turn on the 
power switch and check for 12 volts at both ends of  R5 (no need to have 
the band board installed for that check).  How about at the collector 
(tab) of Q6?

If you have 12 volts at all those places, check the output pin of U5 for 
the presence of 8 volts.  If so, check for 6 volts at the output pin of U6.

If all those are present, turn the K1 off, install the band board, turn 
it on and you should have a display of some sort.

Let us know what happens.

Don W3FPR

[Elecraft] Fw: Inductive relay kick

2009-04-04 Thread Carl , WCØV

- Original Message - 
From: Carl, WCØV wc0...@embarqmail.com
To: k...@att.net
Sent: Saturday, April 04, 2009 8:50 PM
Subject: Re: [Elecraft] Inductive relay kick


 Good point. The diode will conduct the back EMF minus internal voltage 
 when the supply voltage to the coil is removed. You do need a diode with a 
 high enough PIV rating. But even Radio Shack has silicon diodes with 1000 
 PIV rating, 2 amps forward current rating at five for a dollar.

 We make electric actuators where I work, motors with internal rollerscrews 
 and often they get equipped with electric safety brakes (apply when power 
 is removed, release when power is applied). We normally supply 1N4007 
 (1000 PIV rated forward bias) diodes with brake equipped motors.

 50% of those you ask would do that. The other 50% would use a very fast 
 switching diode as you suggest. Both work just fine since the only job is 
 to conduct the EMF coming out of the coil when the actuating voltage is 
 removed. BUT you do need a diode with a high enough PIV rating. Some of 
 our bigger unsuppressed motor brake coils can spit out over 600 vdc when 
 the supply is removed.

 And yes some of our customers hook up the diode or the brake supply 
 backwards and blow the diode (if they don't blow the supply first). 
 Protection is gone, and the back EMF from the relay coil is free to blast 
 wherever it wants to go.

 I am sure the Elecraft relays are way below that. My point to Don was that 
 simply doubling the voltage rating of the coil to get the back EMF is way 
 off. A scope will tell the real tale.

 BTW I got yelled at by a medical tech who pointed out that the pain 
 (real - I tried the relay wire experiment myself) is the voltage going 
 right across your heart. To some, 450 vdc may be a very bad day.

 Hi Carl,

   What am I missing here?   Using a regular silicon diode that 
 has a fast switching time, or even better a Schottky diode wouldn't they 
 clamp at the forward bias of the junction .7 volts of less.   If not how 
 long could you expect the diode to survive that abuse of 75v across the 
 forward biased junction.  If the diode then failed open you would never 
 know your protection was gone.

[Elecraft] K3 Band button suggestion

2009-04-04 Thread Steve Ellington
Since we can't have band stacking and memories are too much trouble, how 
about designating one seldom used button of our choice to be the band 
stacking button. Example: We scroll to 40 meters with the usual band button 
then once we are on 40m, we can use that designated button to scroll through 
pre-programmed locations across the band such as CW, SSB, Digital etc. 3 
spots would be plenty. To me, this seems like a good compromise. In my case, 
I would chose to designate the SUB button since I don't have the sub 
receiver or maybe the RATE button since I seldom need it. Anything would be 
better than using those memories!

[Elecraft] OT: inductive kick stuff

2009-04-04 Thread Rick Shindley
I hope the following will help the people that aren't into electronics all
that much.
 
An inductor (relay coil, solenoid, choke, etc.) stores energy in its
magnetic field.  When the source of current is removed, the magnetic field
will collapse back into the core at fast as it can, limited only by current
flow, if any. Until current flows the voltage can reach many hundreds of
times the actual supply voltage but the polarity is opposite that which
created the field since the magnetic field is no longer expanding outward
but collapsing inward. This is called the flyback effect and it is used to
great advantage when you need 6V, 12V, or 200V from a 1.5V penlight battery.

 
With a diode connected backwards in parallel with the coil, the diode will
become forward biased when the inductor's field collapses. The energy in the
collapsing field is dissipated as heat in the diode and coil winding
resistance.  If the diode is a silicon diode, then the (negative) voltage of
the collapsing field will be limited to the normal forward diode drop (0.7V,
for silicon diodes) .  There is no need for a high PIV diode since the diode
is reversed biased when the relay is energized and that voltage is typically
low, say 12V.  A 50 PIV diode would work fine.  The only real criteria for
the diode are that it be able to handle the current from the collapsing
field.  That's why you don't see signal diodes serving that function.
 
And you don't need a fast diode, either.  The clunky power diode will be
fine.  It has a lot of junction capacitance, which makes it slow, but the
capacitance is in parallel with the (theoretical) diode and NOTHING will
allow the forward voltage to exceed the diode drop (0.7V, for example).  The
added junction capacitance only helps eat the collapsing field energy as
it charges the capacitance until the diode clamps on in forward bias.
 
So, what happens with a diode-protected relay is that the diode will conduct
momentarily when the drive to the coil goes away. A small negative voltage
(diode forward drop) will appear briefly until the stored energy is
dissipated. The drive circuit sees nothing more than a small negative
voltage during that time and thus the circuit is protected.

Re: [Elecraft] Fw: Inductive relay kick

2009-04-04 Thread Don Wilhelm
Carl,

If you look at the datasheet for the relay driver used in the KPA100, 
you will find that it does indeed have integral clamping diodes.
Based on that fact, the inductive kick in the KPA100 should be almost 
zero, but in reality, there will still be a residual hit.  I believe 
that saying it should never be greater than twice the relay coil voltage 
is quite a conservative one - we were discussing the KPA100 application 
in particular, not back EMF in the  general.sense.

You are quite correct - without clamping, and relay coils with 
relatively low resistance, the back EMF can grow very large.  The energy 
in an inductor (the relay coil is an inductor) is proportional to the 
inductance times the square of the current, and if the relay coil 
resistance is low, the square of the ON current through it can be very 
large.

Re: [Elecraft] [k3] Tone/Low Bat indication?

2009-04-04 Thread S Sacco
Hi Dave -

OK, sorry for the misunderstanding; I thought you were talking about the
K3's internal battery.

Now that we have that out of the way:

1) BAT MIN is set to 11.0 v

2) When I measured the voltage using the K3's internal metering:
a) It was 13.6 v at receive
b) It was 10.8 v while transmitting 95 watts output   Clearly, 10.8
 BAT MIN 

3) I measured disconnected and reconnected the Anderson Power Pole connector
at the back of the K3, and the voltage increased to 10.9.

4) I have the power from the power supply (an Alinco DM-330MV) running to a
set of fuses before continuing on to the K3.   It's one of those gold-plated
dressy looking deals that car audio folks use to bling-out their
installation (I got them cheap at Skycraft Surplus here in Orlando about 10
years ago).
   a) I removed both fuses (one for +, one for - ) and treated both the fuse
and the holder with DeoxIT.
   b) At the same time, I treated the PowerPole with DeoxIT.
   c) I also noted the the - lug on the back of the Alinco was slightly
loose, so I tightened it.
   d) My apologies for not doing one thing at a time, and then measuring the
result; that would have been the proper procedure.
   e) Upon the above treatment and actions:
i) The voltage rose to 13.7 v at receive
ii) The voltage rose to 11.4 v while transmitting 95 watts
iii) To add another datapoint, I reduced the power to 45 watts
(typical power when driving my amp) and the voltage was 12.0 v.

Conclusion: Voltage drop due to I squared R losses.

I didn't measure the voltage on both side of the fuses before the DeoxIT
treatment, which was another mistake in my diagnostic approach.  I did so
after the treatment, and noted a voltage drop of only .1 volt (from 12.9 to
12.8) across the fuses while under load.

Thanks for the tip Dave; it was much appreciated!

I've Cced the reflector, and hope this serves as a good example for everyone
to mind their connections.

[Elecraft] FSK Issue

2009-04-04 Thread Dave Reed
I seem to have this recurring problem with FSK on my K3.  Up until now, the
problem was intermittent, often solved by rebooting my computer and/or
reloading MMTTY.  Well, without changing anything, the problem has now
become consistent, persistent and predictable:

 

At 0 - 22W on 80m, or any power level on 6m - 40m, MMTTY (using my
interface) will key the K3 and send normal RTTY tones using the FSK-D data
mode.

 

At 23W and above, on 80m, MMTTY will key the K3, but I only get the high
tone.

 

Of course, if I put the radio into test mode, I get normal RTTY tones.

 

Am I overlooking something obvious?  Going crazy?  SWR presented to the K3
is 1:1 (SteppIR BigIR vertical).

 

AFSK works fine using the AFSK-A data mode, but I don't want to use AFSK.
:-)

[Elecraft] Elecraft CW Net Announcement

2009-04-04 Thread Kevin Rock
Good Evening,
   Today was very sunny and warm (50 degrees).  The first hummingbird of the 
season visited the windows to inform me it was time to set up the feeder for 
him.  He buzzed the windows three times just to make sure he got my attention.  
Just moments ago I was phoned by the Nielson Ratings folks.  They always get a 
kick out of finding someone with no television.  This is the fifth time they 
have surveyed me in the last eight years.  The first flowers to bloom this year 
were not the snow drops but rather some jonquils.  For the last few years they 
have gotten zapped by frost so it was nice to see them get a chance to bloom 
undisturbed.  The forecast is for a week of pleasant sunshine and warm 
temperatures.  It will get to 70 degrees on Monday so I will be rather hot in 
here.  But then we go back to Oregon normal for the rest of the week.
   Conditions on twenty meters were on and off but I was able to make 
consistent, if weak, contacts every day of the week.  Since I was busy with a 
class for the ARES folks I did not have time during the evenings to check.  My 
antenna/propagation class part one went very well.  I started them off with a 
taste of Maxwell's equations in vector form.  I wanted to make sure they were 
alert and awake ;)  From the response I received I could have added more 
calculus during the rest of the lecture.  So, next time I offer this class, I 
will give them some differential equations too.  Calculus allowed me to show 
them things more simply than words would ever allow.  Now I need to finish part 
two of the class which is on more practical aspects of antennas and 
propagation.   

Please join us tomorrow evening.

so choose.

Yes, it does take a  2 button tap to retrieve the contents of any of the 
M1-M4 memories, but if band-sacking memories can only retrieve the 
topmost memory with any one tap, the average number of button taps 
required to retrieve the desired memory with a stack depth of 3 is also 
two taps.

So please tell me that band-stacking is something different than a

Glad that helped,  Steve.

You might want to continue your troubleshooting, though.  I use exactly 
the same Alinco DM-330MV power supply with the same stock Power Pole 
connectors that came with the K3, and while I have considered shortening 
the power cable that Elecraft provides I have not yet done so.  I 
normally have my DM-330MV set for 14.5 volts per the earlier discussions 
here on the reflector about SSB linearity, but I temporarily adjusted 
the voltage back down to 13.6 volts in receive to match your 
conditions.  With the K3 set to 95 watts, I show 13.0 volts in 
transmit.  At 45 watts, I'm holding 13.3 volts.

I'm not sure what the difference might be, but we're getting 
significantly different results from the same power supply.  For what it 
might be worth, I carefully soldered the connections between the cable 
and the Power Pole connectors when I assembled it.

Re: [Elecraft] K3 Band button suggestion

2009-04-04 Thread Steve Ellington
Don:
Most rigs nowadays have band stacking registers. The band selection keypad 
has a button for each band. Each button is capable of remembering at least 3 
frequencies per band. Programming these buttons is automatic.
When we switch between bands, the rig remembers the last frequency we used. 
Let's assume I was on 40 meters at 7250 khz yesterday but today I switched 
to 20 meters. When I push the 40m button, I'll land on 7250 Khz again. Later 
I tune down to the cw band, 7016 Khz, listen a while then jump back to 20M. 
Now we have 2 frequencies stored for 40 meters, one for phone and the other 
for cw. If I push the 40m button again, I'll land on 7015, push it a second 
time and I land on 7250. Eventually all bands that I used will have 3 of my 
favorite frequencies stored simply just by me operating and making no 
particular effort to program the buttons.
TenTec, Kenwood, ICOM, virtually all rigs work this way.
I've tried programming the M1, M2 etc. buttons but sooner or later I hit the 
wrong button and the whole things is screwed up. It's just not intuitive as 
having registers. Since the K3 doesn't have individual band buttons, there's 
not much you can do about it. That's why I suggested that a separate button 
be designated as the band stacking register button for whatever band you 
happen to be using. Simply push that button 3 times and you get 3 different 
frequencies that you have used in the past. How, you ask, did we program 
these frequenciesWell every time you change bands, the last frequency 
used is stored in that particular registry. When you go back to that band, 
that frequency will pop up first but the last 2 frequencies will be 
available by a push of the button.
Hope this makes sense! I'm sure Elecraft is tired of hearing about this but 
lack of this feature is a very common complaint on an otherwise perfect rig. 
Maybe the new panadpter will have these buttons!

My old and greatly inferior 756Pro had band stacking registers, and that 
feature essentially lets you cycle through the last three (in the case 
of the 756Pro) frequencies/mode with just repeated presses of the same 
band-select button.  For example, I could set the rig to 14010 CW with a 
narrow bandwidth, press the 20m band-select button and set that position 
to 14070 USB-D with a wide bandwdith, press the 20m band-select button 
again and set that position to 14195 USB with a medium bandwidth, and 
from that point on repeated presses of the 20m band-select button would 
cycle through all three setups.  On the 756Pro, the stacking registers 
were unique for each band.  It was a nice feature.

 buttons, and you say you want only 3, so you may use only M1-M3 if you 
 so choose.

 Yes, it does take a  2 button tap to retrieve the contents of any of the 
 M1-M4 memories, but if band-sacking memories can only retrieve the 
 topmost memory with any one tap, the average number of button taps 
 required to retrieve the desired memory with a stack depth of 3 is also 
 two taps.

 So please tell me that band-stacking is something different than a 
 stack as used in programming, and I will give up my argument and go 
 off on another tangent about the ills of mis-named functions on a radio.

Re: [Elecraft] FSK Issue

2009-04-04 Thread Joe Subich, W4TV

These symptoms are classic common mode RFI issues.  Typically 
due to unbalanced RF on the shield of the coax coming back 
from the antenna.  SWR has nothing at all to do with common 
mode - swr is measured in differential mode on the inside of 
the transmission line.   

See K9YC's information on common mode RFI at: 
  http://www.audiosystemsgroup.com/RFI-Ham.pdf 

The first thing to do is properly ground the shied of the 
coax (and the shield of the control cable) of the SteppIR 
vertical where they enter your shack and then install 
common mode chokes between the ground window and the 
rest of the station.  After that, install a choke of 6 to 
8 turns on a #31 mix toroid in the FSK line between your 
computer interface and the Aux/Acc input of the K3. 

In all probability the shield of the your coax is acting like 
another radial on 80 meters.  I'd almost bet is it very close 
to an odd multiple of 65 feet (as the coax runs) from the 
antenna to the rig.

 Subject: [Elecraft] FSK Issue
 
 
 I seem to have this recurring problem with FSK on my K3.  Up
 until now, the problem was intermittent, often solved by 
 rebooting my computer and/or reloading MMTTY.  Well, without 
 changing anything, the problem has now become consistent, 
 persistent and predictable:
 
  
 
 At 0 - 22W on 80m, or any power level on 6m - 40m, MMTTY (using my
 interface) will key the K3 and send normal RTTY tones using
 the FSK-D data mode.
 
  
 
 At 23W and above, on 80m, MMTTY will key the K3, but I only
 get the high tone.
 
  
 
 Of course, if I put the radio into test mode, I get normal RTTY tones.
 
  
 
 Am I overlooking something obvious?  Going crazy?  SWR
 presented to the K3 is 1:1 (SteppIR BigIR vertical).
 
  
 
 AFSK works fine using the AFSK-A data mode, but I don't want
 to use AFSK.
 :-)

Re: [Elecraft] K3 Band button suggestion

2009-04-04 Thread Erik N Basilier
Don, I used to have band stacking on my old Yaesu, and now on the K3 I have 
programmed the M buttons to select 3 frequencies in each band. You are 
correct w.r.t. the number of button presses: The K3 always needs two, while 
band stacking requires anything from one to three (if limited to a stack 
depth of 3), which makes two on the average. On the other hand, if one has 
only one favorite frequency in a band, band stacking requires only one key 
press to go there. The term stacking might be justified by observing that 
the last stored frequency within the band is the first on top of the 
stack, but on the other hand, when one accesses successive levels on the 
stack nothing pops off, but the stack contents just rotate.

The advantage of band stacking IMHO is that you only need to use eye-hand 
coordination to reach one button, and you are guaranteed to end up on the 
desired band regardless of intentional or non-intentional programming. I 
have yet to reach the touch typing proficiency stage w.r.t. the K3 
buttons, and have often re-programmed a memory button when my intention was 
to recall a band. At least once I have lost my M button programming when I 
upgraded firmware. That said, I think the BAND and MODE controls are quite 
convenient, and I use them as often as I use the M buttons.

73,
Erik K7TV

[Elecraft] [K2] Aligning CW SSB filters...Crystal heaters running perfect

2009-04-04 Thread Mike-WE0H
OK I found Spectrogram 5.0 runs perfect in Wine within Linux. I aligned 
my CW filters per the N0SS document. All went real easy.

Question though, how to align the SSB filters? What should the filter 
shapes look like? Is there an online document showing me what I should 
be tuning them for? I kind of guessed and tuned so the left skirt just 
went down to the low freq side of the display. I would prefer to see 
what they should look like when tuned properly...hi hi...

BTW, I have three crystal heaters heating the PLL  both BFO crystals to 
40C. So far so good, the radio is dead nuts stable now.

Many thanks,
Mike
