[Elecraft] K3 Beta firmware rev. 2.82

2009-02-11 Thread David Pratt
In a recent message, wayne burdick n...@elecraft.com wrote ...

K3 beta-test firmware revision 2.82 (with DSP rev 2.00) is now
available. See release notes below.

Many thanks for the latest firmware - all installed successfully and 
apparently working okay.

In a future release, would it be possible for the Power Level RF 
indicator to show the mW power when using the K3 with the XV--- 
transverters?  While accepting the limitations of the LCD display, it 
would be useful if the power meter read from 0 to 1.2mW.

Re: [Elecraft] Dynamic Mics on K3

 Giulio,

 You did not say what microphones you were trying to use, only that 
 they were 'dynamic'.  Are you attempting to use Pro-Audio 
 microphones?  If so, check out the information provided by Jim Brown 
 K9YC at http://haminterfacing.pdf/.  Do your microphones have adequate 
 output?  Do they need Phantom Power?  There can be many reasons you 
 are not having success.

 How does the audio sound from the K3 monitor.  You said you did the 
 evaluation on 144 MHz, but what mode?  If it is FM, then many have 
 reported issues with 'thin audio' on FM, and Elecraft is currently 
 working on improvement for that condition.  How does the K3 sound with 
 the microphones on SSB?


Currently I'm using a Shure SM57 dynamic mic. The others are brandless 
or unknown.
The mic doesn't need phantom power, but I agree with you that the output 
level of the microphone maybe is a little low.
The tests I run were on SSB only, no FM or AM. The sound on the K3 
monitor seems perfect (and that points the problem elsewhere, that is a 
test I didn't make until a minute ago).
After a brief test on hf (listening on a K2) the audio seems fairly 
better than on 144 MHz. I've a feeling about the XV144 It seems that 
at a certain point in the IF path the signal become reduced in 
bandwidth, maybe the filters are a little off band

Re: [Elecraft] K3 Beta firmware rev. 2.80: Improvements to AFSK-A, DATA-A, SSB, AM, FM, DVR

hi Wayne, 

wayne burdick schrieb am 10 Feb 2009 um 15:00:

 * SSB/DATA-A/AFSK-A TRANSMIT POWER LEVEL: Power output in these
 modes now more closely tracks TUNE power.  We recommend setting
 CONFIG:TXG VCE to 0.0 dB after loading this release, then adjusting only if
 necessary.
 
 * DATA MODE ALC METERING: ALC metering for DATA-A and AFSK-A
 modes has been adjusted to make the transmit audio level easier to 
 adjust.
 As before, the recommended audio level for transmission is 4 to 5 bars. 3
 bars will appear as soon the minimum required level for good S/N ratio has
 been reached.

I tested the new firmware with my K3 + Ptc-2 TRX modem built inside the 
K3 and I think you have made a good improvement with the latest firmware
2.82. 
The output measured on my LP-100 meter is in a 5% range close to the 
power setting of the K3. I had to set the LINE IN GAIN higher than before, it 
is now at 20, before it was at 12. My output settings in the TRX-PTC 
modem are set to 1000mV for PSKA and 800 mV for FSKA. TXG VCE is 
set to 0.0dB This combination gives me the recommanded 4 bars of ALC. 
Throughput is good as far I can tell - I'll have to check this in the evening 
with better conditions to the RMS oe3xec which I can connect on 80m in 
distance of 280 nautical miles. 

thank you very much, that's what I like with you and the K3. It's getting 
better every time ;-)

 To: Elecraft Reflector Elecraft@mailman.qth.net
 Message-ID: 59aa74da58ea67722f9def82c0e2a...@elecraft.com
 Content-Type: text/plain; charset=US-ASCII; format=flowed

 The K3 is a down-conversion superhet that uses high-level signal 
 injection to achieve its excellent dynamic range. Short of adding many 
 more pounds of shielding and elaborate cable dressing, there's no way 
 to completely eliminate the few spurious signals that rise above the 
 noise floor.

 These Fast-tuning birdies result from UHF harmonics of the signal 
 sources that leak back into the main mixer. In some cases they combine 
 and end up in either the I.F. or R.F./image range of the receiver. 
 Typically, they involve 9th-order or higher harmonics of the VFO. 
 That's what makes them fast: if you move the VFO 100 Hz, the pitch of 
 the birdie will shift on the order of 1 to 2 kHz.

 While it is possible to attenuate some spurious responses by moving 
 coax cables around, there is a firmware-based approach that we're 
 working on. The general idea is to shift the 1st LO and BFO a small 
 amount, simultaneously, when the VFO is tuned to specific frequencies. 
 If the shift is small relative to the communications bandwidth in use, 
 it will hardly be noticeable when the VFO is tuned over a mapped out 
 spot in the tuning range.

 I have this new firmware nearly completed, and in early tests, it 
 appears to work very well. Fast-tuning birdies that are mapped out 
 pretty much disappear as the VFO is tuned over them. The upshot is that 
 you can have your cake (outstanding dynamic range in a rig that weighs 
 less than 10 pounds) and eat it, too (no annoying birdies).

 If you'd like to try a field-test version of K3 firmware that includes 
 this new feature, please e-mail me directly.

 73,
 Wayne

[Elecraft] ElectroVoice 664 mic to K3?

2009-02-11 Thread TMorton
Hello,
I have a EV664 Dynamic Cardioid mic which I used with Orion II thru a 
W2IHY box. The 664 has a four pin XLR plug from its' base.

Question:

1. Can I use this directly into the K3? Without using the W2IHY..

2. What are the pinouts to make it work with K3 into front panel?

I installed the new beta last and tested the new output power control. I
don't see any improvement in PSK31 output power using DATA A mode. I still
get nearly twice the output power than I have dialed in by the PWR knob. In
the previous firmware, the measure output power in CW modes agreed with the
PWR knob setting, but now the power output in CW is 20-30% higher than the
setting.

I will try to redo the transmitter gain calibration to see if this helps.

[Elecraft] K2/100 problem on 80 meters

2009-02-11 Thread Pierre
From Don W3FPR

But, if you have added the KPA100UPKT, I must ask if your upgrade kit included 
a new C31 capacitor of 0.22 uF value.  Many KPA100UPKT kits did 
not include this capacitor until recently.  If this situation fits your case, 
send an email to pa...@elecraft.com asking for a new capacitor...

Sometime ago (around 2007), I ordered and received the KPA100UPKT upgrade kit 
for my K2/100 #5170, but never installed it. I will do it soon.
After checking the (old) package and the manual page, I see that there are new 
parts in the instruction errata which I did not receive in 2007: 5 capacitors 
and a crystal... so will ask Elecraft for them before I start that upgrade.

Thanks to all for you suggestions.

[Elecraft] K3 to THP 1.5KFx connector

2009-02-11 Thread Jim Spears
I researched the 5 pin DIN connector that is on the back of the THP 1.5KFx
amp's Yaesu interface jack and have a part number.  This will enable any K3
which has the pullup resistors for band data installed on the KIO3 through
the ALC mod or factory cut in to output band data to the amp and have it
follow band changes just like the K3 was a Yaesu transceiver.

 

The SwitchCraft part number is:  12GM5M   (presumably
series 12GM, 5 pin, male)

The Mouser part number is:502-12GM5M

 

It is important to note that this is a male connector with 5 pins
distributed around 240 degrees.  The more common 5 pin DIN connectors have
the 5 pins distributed around 180 degrees, these will NOT work.

 

Wiring is straightforward from the DB15 connector to the 5 pin DIN.  4
signals plus ground.  And ALC as a separate cable for those so inclined.

 

www.zerobeat.net/mediawiki/index.php/K3_to_Tokyo_Hy-Power_HL_1.5KFX_amplifie
r

 

shows the wiring diagram; presumably a K3 with the pullup resistors
installed internally does not need the external 5 volt source.

Re: [Elecraft] K2/100 problem on 80 meters

2009-02-11 Thread Don Wilhelm
Pierre,

Yes, there was an early version of the KPA100UPKT and only a few were 
shipped.
You may not need all the added parts - they were added because some 
KPA100 owners had added mods to correct other problems, so the parts 
were added to allow any KPA100 to be restored to the standard parts.

You will definitely need the new capacitor for C31, and you may need the 
new crystal.
R4 should be changed to 100k if it has a different value
New capacitors for C80 and C81 were included because some builders had 
changed them in an attempt to cure a low power situation on 20 and 17 
meters.
You should have new resistors to install at R19 and R20 - inductive 
resistors here were the real cause of the low power on 20 and 17 meters.
If you had never changed C71 and C72 to reduce the click on unmute 
problem that some K2 owners experienced when the KDSP2 was installed, 
those capacitors will not be needed.

Don W3FPR

[Elecraft] All new K3s include Neg. ALC and Band Data pull-ups

2009-02-11 Thread Eric Swartz - WA6HHQ, Elecraft
ALL new K3s shipping now include the negative ALC mod and the pull-up 
resistors on the band data outputs.

enable any K3 which has the pullup resistors for band data installed 
on the KIO3 through the ALC mod or factory cut in to output band data 
to the amp and have it follow band changes just like the K3 was a 
Yaesu transceiver.

Hello Giulio,

That mic will work just fine with a K3. I use an RE16, which is 
electrically quite similar. A correction to the link that Don 
gave you. It's

http://audiosystemsgroup.com/HamInterfacing.pdf

With any pro mic, you should adjust the TX equalizer to reduce 
the level of the lowest audio bands and boost the level of the 
two highest bands. The TXEQ settings in my K3 are:

  50  -16dB
 100  -16dB
 200  -10dB
 400   -3dB
 8000dB
16000dB
2400   +3dB
3200  +10dB 

To set mic gain and compression, follow the instructions in the 
K3 manual. My compression control is set to provide an indicated 
10-14dB on the compression meter on peaks. I'm a serious 
contester, and my rig consistently gets reports of excellent 
audio from other serious contesters, including some who are also 
audio engineers.

Re: [Elecraft] ElectroVoice 664 mic to K3?

I have a EV664 Dynamic Cardioid mic which I used with Orion II thru a 
W2IHY box. The 664 has a four pin XLR plug from its' base.

The EV 664 is the grandfather to the RE16 that I use, and is an excellent 
choice for ham radio. You should feed the 664 directly into the K3. Use the 
wiring in the Ham Interfacing link I just posted, and also the same TXEQ 
settings. 

With respect to wiring -- see page 47 of the tutorial, and note that pin 
numbers are shown for the Standard 3-pin XLR connector wiring used in pro 
audio. If your mic has a 4-pin XLR the wiring will be different. By the way 
-- the 4-pin XLR is NOT a Standard for audio anywhere in the world. 

You can find the mic wires by probing between the connector pins with an 
ohmmeter. The mic capsule (the two balanced wires) will measure as some low 
resistance value on the order of 50 ohms, AND you will hear a click if you 
put your ear close to the mic. 

I'm looking at the original data sheet for a 664. It has both high 
impedance and low impedance outputs. You want the LOW impedance output for 
the K3. For the connector that is built into the mic, pin 1 is shield, pin 
3 and 4 are the balanced low impedance outputs. 

The 664 has some built-in equalization that boosts the highs an bit and 
rolls off the lows a bit. For that reason, you don't need quite as much 
TXEQ as for the RE16 that I'm using. For the 664, I would use about 3dB 
less cut at 50, 100, and 200 Hz, no EQ at 400 Hz, no boost at 2.4 kHz and 
about 5 dB boost at 3.2 kHz.

Jim's settings look good for standard bandwidth SSB.  For the K3's ESSB

50-100Hz bands can be flat or even boosted slightly, depending on the

to no more than +5-6 dB, again depending on the mic's response.  Results 
will vary, but that's a good place to start with a dynamic mic.

I'm not sure if anyone has measured the K3's TX ESSB distortion products 
between 50-100 Hz (sourced through the front panel mic connector), but 
backing off on TX output power and running a slightly elevated V+ may be the 
neighborly thing to do.

[Elecraft] Mic Audio Problems with K3 and DXD

2009-02-11 Thread Donald Butler
This query goes to anyone out there who might be using a K3 with a TopTen DX 
Doubler.

 

I recently got my new K3, and now have it and an FT1000MP connected to a DXD in 
a SO2R setup, using prefabricated cables purchased from TopTen, and a Heil 
Proset plus headset.  All is well with the MP, which has worked fine with the 
DXD for several months.  On the K3, ptt, key and earphones all work fine, but 
I'm having trouble with a  strange rumbly, gravelly hash and feedback on 
transmit with the mic  (also in test mode).   The mic works fine when connected 
directly to the K3.  It also works fine to the MP through the DX Doubler, but 
when I connect the mic to the DXD and then to the K3 via the cable I get hash 
and a rumbling windy sounding feedback, even with the monitor off.  There is no 
hum on keydown when I do not speak.   It's also clean when I whistle into the 
mic, but when I speak I get the hash and rumbling.  I've confirmed its presence 
with on air testing.  I've tried front and back mic connections on the K3. and 
both high and low mic gain settings on the menu. Bias is off.  I've also tried 
adjusting TX EQ on the config menu.  Again, it's perfect when connected 
directly to the radio, but bad when cabled through the DXD.   I get identical 
hash on the K3 whether I'm connected to Radio 1 or Radio 2 connectors on the 
DXD . and the MP works fine on both.

 

It would seem that the problem must be in the cable connecting DXD to K3, but 
the cable seems to check out OK.  It has good continuity on all pins and all 
are isolated from one another except the common shield which is as it should 
be.  I did note that the mic ground lead is not a shield, but just another wire 
inside the main cable?  I added a shielded mic line with isolated shield to 
rule that out as a problem resulting in no change.

 

Has anyone else experienced similar problems?   If so, any suggestions?

 

Thanks

 

Don, N5LZ

[Elecraft] KAT3 auto select by high SWR?

2009-02-11 Thread Gary Smith
I've been wondering if there is a setting I might have missed which 
tells the KAT3 to seek a better SWR as I change bands or go to 
different areas of a given band.

I always have to  tap the ATU-Tune button to have it adjust for a 
given location I am on, is there any setting I've missed to have the 
ATU automatically do this without my having to tell it to do so? 

Thanks,

Gary

I agree with Paul that for ESSB, less equalization is appropriate. I would, 
however, still apply steep low cut at 50 Hz and 100 Hz to any pro mic, 
simply because there's no useful speech content in those bands, but most 
mics will produce popping and other breathe noise in that spectrum, and 
most shacks will have a lot of acoustic noise in that spectrum. 

All single-D mics (virtually all popular handheld vocal mics) suffer from 
proximity effect, so some low cut is also needed for the 200 Hz octave band 
with these mics. 

As to high frequency EQ -- this EQ compensates for the rolloff produced by 
the TX filter and the RX filter, so if you're transmitting through a wide 
filter, I would not use that EQ. 

That said, I consider ESSB to be quite wasteful of the limited spectrum 
available to hams. It's fine to use it when there's little activity on the 
bands, but those who are selfish enough to use it on a crowded band make me 
want to build and fire up an arc transmitter.

Re: [Elecraft] K3 to THP 1.5KFx connector

2009-02-11 Thread Phil Debbie Salas
The Yaesu band data connector on the back of the 1.5KFx is really a 6-pin 
DIN connector.  They only use 5 of the pins (the center pin is not connected 
to anything).  So you can use the expensive 5-pin 240-degree DIN, or you can 
use the cheap 6-pin DIN (Mouser part number 71-0276 @ 66-cents).

[Elecraft] K3 configuration finalization plus diversity receive antenna question

2009-02-11 Thread James Sarte
Dear group,

 

I'm just about ready to place my order for a K3 (hopefully by tomorrow.yay!)

 

After some good discussions with list members, I think I've finally narrowed
down my option choices:

 

*   K3/100 kit
*   KAT3 ATU
*   KBPF3 gen. cov. Module (1 unit, will be placed on SUB receiver)
*   KDVR3 Dig. Voice recorder
*   500Hz 5 pole (2 units, one on each receiver)
*   6KHz filter (1 unit, will be placed on main RF board for ESSB
experimentation)
*   13KHz FM filter (2 units, one on each receiver)
*   40Hz filter matching for 2.7 and 500Hz filters
*   KRX3 sub receiver
*   KTCXO3-1 1ppm oscillator
*   KXV3 xverter interface
*   MH2 hand mic

 

I'm mostly an SSB guy, but do play around with PSK31 and RTTY.  I also like
to listen to shortwave broadcast stations.  The sub receiver will get the
gen coverage module plus a 13, 2.7, and 500 filter.  The 2.7 and 500 will be
matched for diversity receive.  The FM filter on the RF board will be used
for 10m repeaters, while the FM filter on the sub will be used for broadcast
reception.

 

I don't know if anyone here has heard of the AOR LA-390 active loop RX
antenna, but I'm thinking this might work well for my diversity experiments.
I'm space limited, and this thing can be kept on my window ledge.

 

http://universal-radio.com/catalog/sw_ant/2320.html

 

I plan on using a Buddipole for my TX antenna connected to input 1 on the
KAT3.  The AOR loop antenna will be connected to the AUX RF BNC input.  The
loop antenna will also be used for SWL'ing.  I'm assuming that the gen
coverage module will function with the sub receiver using the AUX RF BNC
input?

 

Does this sound like a well rounded package for my needs?

James KC2UEE

[Elecraft] K3 Sub and Main Synchronization

2009-02-11 Thread Tom, N5GE
Today when I turned on my K3 #806 I noticed that when the sub and main
vfos were both on the same frequency they sub and main receivers were
not quite on the same frequency.  I would guess by the wavering that
they are probably 2 to 5 hz off per second.  The wavering is heard in
the band noise on 6m.

Is there an adjustment I can make to get them dead on.  It's not the
first time I've noticed this.

[Elecraft] Modulation on XV144 was: Dynamic mics on a K3

2009-02-11 Thread Giulio Pico - IW3HVB
After a few good suggestions by Don, Jim and Fern I run a few more 
tests, coming at the conclusion that the problem was not the MIC, or its 
interfacing with the K3 or the radio itself.
The audio on HF bands is simply perfect, with or without compression 
(and comp acts exactly as it should).
But the problem on 144 MHz is still there, so the problem must be on the 
XV144. The Power supply is the same for both the radio and the xverter, 
tried switching and stabilized with no differences.
I've no idea where to look..  Changing the drive power (I'm using 
the KXV3 module) does'nt produce any difference as well.
Any clues?

Have you checked the 3rd decimal digit (Hz) by switching in FINE? I once had
this and noticed that this digit which isn't normally displayed was
different for MAIN and SUB

Re: [Elecraft] Calibration of KXV3 module

2009-02-11 Thread James Sarte
Hi Stephen,

 

Yes, I'm familiar with 50 ohm BNC network terminators.  This will work
without issue and get me properly calibrated?  Otherwise, I can always get
an SO239 to BNC adapter and run a cable into my 300w 50 ohm dummy load.

James,

It will only (possibly) be 50 ohms at the frequency for which the stubby
antenna is designed, which will almost certainly not be the frequency coming
out of the XVTR jack, so it won't work.  I expect a 47 ohm resistor would be
close enough, but ideal for this purpose would be a 50 ohm BNC termination
that used to be used in pc networking if you are familiar with that.
Otherwise a coax cable (via adaptors if necessary) from a good dummy load to
the transverter terminal would be fine.

Hope that helps

[Elecraft] WTB: 6KHz AM Filter

2009-02-11 Thread James Sarte
Dear group,

 

Hopefully a wanted-to-buy ad is permitted on the reflector, but I'm
wondering if someone has a 6 KHz AM filter they're willing to sell?
Elecraft is back-ordered until 20 March, and I would like to assemble my kit
all at one time.  I will be placing the AM filter on the main RF board, and
will have a sub receiver on top of it. I'd hate to disassemble the sub
receiver just to install a filter on the main board at a later date.

Re: [Elecraft] Modulation on XV144 was: Dynamic mics on a K3

2009-02-11 Thread Don Wilhelm
Giulio,

Unless the XV144 is operating in a non-linear region, it should not 
distort the SSB signal.  Should be easy enough to check the linearity if 
you have a good power meter for 144 MHz.  Go to CW and drive the 
transverter with 1/10 the normal power - it should have 1/10 the normal 
output - now increase the drive to 1/5 of normal and check again - 
continue until you have covered the entire power output range in 
increments.  If the transverter output does not track the input level, 
check the XV144 PA bias adjustment.

You might want to connect the KXV3 IF output to an indoor 10 meter 
antenna and listen to the 28 MHz output on another receiver with a short 
antenna (adjust to give an S-9 signal into that receiver).  That will 
tell you if the 28 MHz KXV3 output is clean.

73,
Don W3FPR

Giulio Pico - IW3HVB wrote:
 After a few good suggestions by Don, Jim and Fern I run a few more 
 tests, coming at the conclusion that the problem was not the MIC, or its 
 interfacing with the K3 or the radio itself.
 The audio on HF bands is simply perfect, with or without compression 
 (and comp acts exactly as it should).
 But the problem on 144 MHz is still there, so the problem must be on the 
 XV144. The Power supply is the same for both the radio and the xverter, 
 tried switching and stabilized with no differences.
 I've no idea where to look..  Changing the drive power (I'm using 
 the KXV3 module) does'nt produce any difference as well.
 Any clues?

Re: [Elecraft] Calibration of KXV3 module

2009-02-11 Thread Eric Swartz - WA6HHQ, Elecraft
This will not work. The HT antenna is almost guaranteed -not- to be 50 ohms, 
especially at the nominal 28 MHz output of the xv port. 

The only place this antenna will be even close to resonance is at its operating 
fequency (I'm assumung 144 or 432 MHz). And HT antennas are notoiously variable 
in their actual impedance, since it usually depends on the interaction with you 
body when you hold the HT.

You need a 50 ohm resistive termination.

Re: [Elecraft] 12v acc out

That means voltage is available at the 12V ACC socket when the K3 is 
'switched on' - no relationship with transmit.

That labeling is consistent with what has been used for years on audio 
equipment - the non-switched receptacles are always on, and the switched 
receptacles are powered only when the device is powered.  No K3 speak 
at all.

I tried to redo some calibration of the quiescent current and the

Now the only thing to solve is about the PTT, and we are ready to give

For those wanting TTL outputs on the I/O board, you may now replace your old

Excellent reasons to post an *answer* ON the reflector. 

1) Without going into people's motives, from time to time someone will make
a mistake answering a question for another. They'll make a wrong assumption
or simply be incorrect in their understanding. When that answer is posted
publicly, others will read and correct it and *everyone* benefits. 

2) Some claim off-line posts reduces the number of messages, but my
experience suggests that just the opposite is true. For every question
asked, there are several wondering the same thing. One answer on the
reflector answers them all and often even brings up other questions. And
that's what it's all about.

Eric does not tolerate flames or even consistently impolite behavior,
making this forum is a safe place for newbies and experts alike to talk in

I will disagree with Jim on one point. I've followed this reflector since
2000. From time to time we've had someone spend time here who is very hard

and Don W3FPR. (My apologies to many others whose calls/names don't come to
mind immediately who also take their time to provide meaningful and useful

Re: [Elecraft] Calibration of KXV3 module

2009-02-11 Thread Bruce McLaughlin
If you use a dummy load, you may wish to be certain it's okay for VHF.  Some
dummy loads which are primarily designed for HF frequencies become rather
reactive on VHF.  I think the length of the internal leads in the device had
some inductance and/or capacitance to the mix and, therefore, below
presented to the radio is no longer a pure resistance.

It will only (possibly) be 50 ohms at the frequency for which the stubby
antenna is designed, which will almost certainly not be the frequency coming
out of the XVTR jack, so it won't work.  I expect a 47 ohm resistor would be
close enough, but ideal for this purpose would be a 50 ohm BNC termination
that used to be used in pc networking if you are familiar with that.
Otherwise a coax cable (via adaptors if necessary) from a good dummy load to
the transverter terminal would be fine.

Hope that helps

[Elecraft] K2-XV222 RFI Susceptibility Problems - a solution found

2009-02-11 Thread Steve Kavanagh
A couple of weeks ago I posted here regarding a problem whereby transmitting on 
my 6m rig cause my XV222 (connected to K2/K60XV) to key up.

It appears that if any moderate amount of stray RF ends up on the tranmit IF 
line (probably due to imperfect shielding of the transverter rear panel jacks), 
this power is then detected by the power detector diode on the K60XV board, 
which then apparently triggers the K2 to switch the state of the 8R line.  This 
then keys the transverter.

No word yet from those in the know as to whether this firmware behaviour in the 
K2 is to be expected or not.  Id be interested in hearing the results if anyone 
else wants to try injecting up to 1 mW of RF (HF or VHF...it shouldn't matter 
much) into the K2/K60XV XVTR OUT jack (while receiving) and checking to see 
what happens.

I have found a solution which works at my home station.  That is to put a 
filter in the transmit IF line which passes 28 MHz but does not pass 50 MHz.  
At present I have it mounted in an external box with a short coax cable to the 
XVTR OUT jack on the K2.  I think it still needs a little tweaking to give a 
good match so that the K60XV will give full output in transmit, but the odd 
effects when I transmit on 6m have completely disappeared.

I may still work on improving the XV222 shielding in case the problem is worse 
in my rover setup.

Steve VE3SMA

Re: [Elecraft] K3 configuration finalization plus diversity receive antenna question

2009-02-11 Thread James Sarte
Hi Bruce,

 

No, the 13KHz filter will be used for AM SW/MW/LW reception, not FM on the
sub.  The other FM filter on the main will only be used for 10m FM TX/RX.

 

Here's an excerpt from a conversation I had with another fellow regarding
the use of FM filters for AM broadcast reception:

 

 Just to make sure I understand you, the AM filter is only required if 

 one desires to transmit in AM or use ESSB.

 Otherwise, AM reception like SW can still be piped through the 13KHz 

 FM filter?

 

Correct, I use the FM filter for listening to AM broadcast or SWL on a
fairly regular basis. 

 

 How does the audio of AM SW sound going through the FM filter?  

 Bandwidth is obviously wider, so I'm assuming higher fidelity?

 

Somewhat higher fidelity.  The K3's DSP has a fairly sharp cutoff at 4200 Hz
so you will never get more than that but the FM filter allows the full 4.5
KHz where the AM filter starts to roll off at 3 KHz but still has some audio
response down the filter skirts.  I hope that someday Elecraft will open
up the audio in AM so we can hear 5.5 or 6 KHz which as good as it gets
these days. 

 

Hope that helps to clarify.  

 

73,

James KC2UEE

Subject: RE: [Elecraft] K3 configuration finalization plus diversity receive

That sounds like a well-rounded package, although, I'm a bit confused by
your plan to use the FM filter on the sub receiver for broadcast reception.
The K-3 will not go to the FM broadcast band and I don't think you can get
there using a transverter either.  Also, the 13 kHz roofing filter, and the
DSP are not really wide enough for broadcast FM.  The 15 kHz deviation is
such that I think you will have considerable distortion on a system designed
for a maximum of 5 kHz deviation if it is recognizable at all.  I could be
mistaken about that, but you may want to check with others.  I also wonder
if you could save a bit of money by having only one 13 kHz filter installed
on the main receiver.  Assuming it will work for FM broadcast reception,
unless you plan to listen to FM broadcasts for long periods of time, I would
think using the main receiver for that purpose would probably be sufficient.
It also could be used for FM transmission on the ham bands.  As I am sure
you know, you cannot transmit using the sub receiver.  I have 2 K3s.  The
older unit has an FM filter installed in the main receiver.  The newest unit
has no FM receiver filter since my use of FM is likely to be very limited
and certainly not at all until 10 meters begins to work again.  But your
plans may be different and you may have different needs.

 The K3 is a down-conversion superhet that uses high-level signal 
 injection to achieve its excellent dynamic range. Short of adding many 
 more pounds of shielding and elaborate cable dressing, there's no way 
 to completely eliminate the few spurious signals that rise above the 
 noise floor.

 These Fast-tuning birdies result from UHF harmonics of the
signal 
 sources that leak back into the main mixer. In some cases they combine 
 and end up in either the I.F. or R.F./image range of the receiver. 
 Typically, they involve 9th-order or higher harmonics of the VFO. 
 That's what makes them fast: if you move the VFO 100 Hz,
the pitch of 
 the birdie will shift on the order of 1 to 2 kHz.

 While it is possible to attenuate some spurious responses by moving 
 coax cables around, there is a firmware-based approach that we're 
 working on. The general idea is to shift the 1st LO and BFO a small 
 amount, simultaneously, when the VFO is tuned to specific frequencies. 
 If the shift is small relative to the communications bandwidth in use, 
 it will hardly be noticeable when the VFO is tuned over a mapped
out 
 spot in the tuning range.

 I have this new firmware nearly completed, and in early tests, it 
 appears to work very well. Fast-tuning birdies that are mapped out 
 pretty much disappear as the VFO is tuned over them. The upshot is that 
 you can have your cake (outstanding dynamic range in a rig that weighs 
 less than 10 pounds) and eat it, too (no annoying birdies).

 If you'd like to try a field-test version of K3 firmware that includes

 this new feature, please e-mail me directly.

actively respond both with solid answers, and with solutions in the

This communication is the primary reason why the K3 runs rings

If you really need a terminal emulator and can't whip one up quickly,  
you can try the one that is built into AVR Tools:

http://homepage.mac.com/chen/w7ay/AVR%20Tools/index.html

Use the download tab at the top of the page.

Once launched, just select New Session from the file menu, then tab  
over to the Terminal tab and you should see the interface shown at the  
bottom of the above page.  Click on Open Connection and you will get  
an emulator window.

The serial port settings are saved to the session file (in the File

Your problem is easy to fix.  I also use a Shure SM 57 on my K3.

It is a professional microphone, and is Low Impedance.

You need to use an in-line impedance matching transformer.

I use a Shure A95UF with an adaptor cable I made myself.  They are  
inexpensive and work very well.

Companies like Shure, Audio Technica, Radio Shack, Sescom, and many

Ok I read the manual and I have been unable to program the m1-m4 keys or the
0-9 keys.  I can program a normal memory just fine.  

Is there a menu setting that I am missing or did I have to do something in
the K3 utility program to get this to work?

 Subject: [Elecraft] Terminal for Mac users


 As a long suffering Macintosh user I was pleasantly surprised when I
 discovered that Elecraft actually makes a version of the K3 utility
 available for us Mac users. However my original euphoria was tempered
 a bit when I discovered our version was missing the very useful
 Terminal program. I'd like to encourage Elecraft to add that
 capability to the Mac software. After all, we are K3ers too and would
 appreciate having the same advantages given to our Microsoft brothers.

Re: [Elecraft] Dynamic Mics on K3

2009-02-11 Thread Kenneth Lopez

Giulio,

I had a brain fade

I just realized, I only use the Shure A95 transformer when driving  
the High Impedance input of my Collins.  But that is something to  
keep in mind.


The K3 input should accept the SM57 directly with the proper cable  
wiring.


You are correct:  your problem is not the microphone.

By the way, I get very good audio reports with mine.

Jim K9YC's suggestion to roll off the low end at 50Hz and 100Hz is a  
good one.


The SM57 has quite a bit of proximity effect and you should keep your  
distance to at least 3 or more.


I use a fairly large windscreen on mine as well.

Enjoy!

Cheers,

Ken N6TZV

After a few good suggestions by Don, Jim and Fern I run a few more
tests, coming at the conclusion that the problem was not the MIC,  
or its

interfacing with the K3 or the radio itself.
The audio on HF bands is simply perfect, with or without compression
(and comp acts exactly as it should).
But the problem on 144 MHz is still there, so the problem must be  
on the
XV144. The Power supply is the same for both the radio and the  
xverter,

tried switching and stabilized with no differences.
I've no idea where to look..  Changing the drive power (I'm using
the KXV3 module) does'nt produce any difference as well.
Any clues?

Re: [Elecraft] Dead K2 After nearby power surge

2009-02-11 Thread Don Wilhelm
Fred,

In cases like yours, first step is to connect a dummy load to the K2 
just in case it is trying to transmit - it is not good to enter transmit 
state without a load on the PA transistors.  If it is a K2/100, remove 
the KPA100 and connect the dummy load to the BNC antenna jack on the 
lower rear panel.

First thing is to check the state of the 8T and 8R voltage rails. Those 
are easily checked at the anodes of D6 and D7.  If D7 anode has 8 volts 
on it while D6 anode has zero volts, then the K2 is in a transmit 
state.  If both D7 and D6 anodes have 8 volts present, power it only 
briefly while making further checks lest some components overheat.

If both 8T and 8R are present, you need to check the state of the RX 
signal at the gate of control board Q4 as well as the TX signal at the 
gate of CB Q3 - one should be on (about 5 volts) while the other should 
be off (near zero volts).  If both of these are on, the microprocessor 
was zapped with the power surge, but if only one is on, the problem is a 
shorted Q3 or Q4 on the control board.

I also pulled the control board and re-powered the unit with the control

the control board and re-powered the unit.  The display came on for just a
few seconds with the Elecraft name and then went blank probably after the
12V pulled down.

I am not quite sure where to look to further isolate the issue.  I know the
unit was on the 40 M band when the problem occurred.

Re: [Elecraft] terminal window in k3 utility

2009-02-11 Thread Don Wilhelm
Gary,

Yes, I believe you can do that.  Set the K3 for PSK D data mode and tune 
the K3 (with a narrow filter) until you hear the PSK 'warble'.  You can 
send using either the paddles or the text input area of the K3 Utility's 
Terminal tab.  The decoded receive text will be displayed in the larger 
screen area.  Be certain to select PSK 31 in the terminal window.

If you succeed with PSK, you can also operate RTTY in a similar way - 
select RTTY in the terminal window and set the K3 for FSK D.

Remember that sending IM (as one character) is the immediate stop TX 
indicator - otherwise there is a delay after you stop sending to go from 
transmit to receive.

Re: [Elecraft] (no subject)

2009-02-11 Thread Don Wilhelm
Mike,

The 0 - 9 buttons are 'quick memories' and are the same as normal 
memories 0 thru 9.
If you have data stored in the normal memories 0-9, then tapping MV 
followed by a tap of the appropriate button should retrieve the memory 
contents.

If you want the 0-9 buttons to act like 'band select' buttons, then set 
the CONFIG: MEM 0-9 menu to BAND SEL and once settings are stored for 
any frequency in a band, those memories will return to the last used 
frequency, mode, antenna selection, filter selection on that band.

You can also use the 0-9 buttons to store those memories.  Set up VFO A 
and VFO B each with their modes and other settings.  Then tap VM 
followed by a tap to one of the 0-9 buttons.  To retrieve, tap MV 
folowed by a tap to one of the keypad 0-9 buttons.


The M1-M4 buttons are similar, but are PER BAND.  That means you must 
select the band first.  Then you may store or retrieve the memory 
contents for each of the 4 buttons.  Tap VM, then tap the M1-M4 button 
to store.  Tap MV followed by one of the M1-M4 button to retrieve.

Re: [Elecraft] terminal window in k3 utility

2009-02-11 Thread Dick Dievendorff
The K3's Utility's Terminal page program uses the K3's internal decoder and
shows the output on a PC screen.  Although you might send with paddles, you
may also use the PC keyboard.  There are also a few memory buttons to
store things you might say often, like your call, QTH, etc.

There are other full feature terminal programs like MMTTY and DigiPan that
use the computer's sound card for decoding.  The K3 Utility's terminal
program was intended for casual kick the tires sort of use and to show off
the K3's ability to decode CW in the radio.

Supported modes are CW, RTTY and PSK 31.

 Elecraft was again shown and the frequency of 7100 was briefly displayed. 
 When then display went out I measured the anodes and cathodes of both d6
 and d7 and measured nearly zero volts on both. 
 

I tested the voltages on D6 and D7 anodes again when I powered up.  I had to
power up twice, but each showed around 7 volts before they fell to near
zero.  I have found that I can let the unit sit for a few minutes before I
re-power and I don't have to pull the control board to reset the relays. 
This only gives me about 2 seconds to make the measurement.
The voltage on the gate of Q4 is 5 volts.  The voltage on the Gate of Q3 is
close to zero for the brief period I have to make the measurement.  After a
few moments the gate of Q4 drops to zero.

 How do I tell which is shorted?  I made the following measurements to
resistance measurements referenced to ground.

Q3
  S  - 0.4 M
  G  - 5.4 M
  D  - 8.1 M

Q4
  S  -  0.3 ohms 
  G  -  3.9 K ohms
  D  -  8.1 K ohms

I am assuming the culprit is Q4.  Am I correct?  Is it possible the
something else is fried that may take out Q4 if I install a replacement?  I
still have 4 boards that I have not built (SSB, DSP2, AT and NB).   I
believe at least one of these has a 2N7000 I can rob for a temporary
replacement.  I just don't want to install it until I am sure another
failure somewhere else upstream won't cause it to fail.  Are there any other
items I should check before I replace the failed transistor?  

Thanks,

Fred

Re: [Elecraft] Dead K2 After nearby power surge

2009-02-11 Thread Don Wilhelm
Fred,

Zero volts on both is way better than 8 volts on both - at least the K2 
is not trying to transmit.

Check the gates of Q3 and Q4 on the control board.  The gate of Q4 
should be at 5 volts and the gate of Q3 should be near zero.  If that is 
true (and only if that is true), short the drain of Q4 to its source and 
see if the 8R voltage rail comes to life - 8 volts at the anode of D6.
If so, replace Q4.  If still no 8 volts on 8R, then something is wrong 
with Q2 (likely open).
OTOH, if the gates of both Q3 and Q4 are near zero volts, you have a bad 
microprocessor output.

 I pulled the control board again to reset the relays and then reinstalled it
 to make the measurements on D6 and D7.  When I powered the unit, Elecraft
 was again shown and the frequency of 7100 was briefly displayed.  When then
 display went out I measured the anodes and cathodes of both d6 and d7 and
 measured nearly zero volts on both.

[Elecraft] K3: A nice black cover to hide the front panel MIC socket

2009-02-11 Thread KM5Q
I got tired of reaching around the mic plug on the front panel, so I  
made an adapter to plug mic and PTT into the rear. Then I got tired of  
seeing the empty mic socket. I found a perfect way to hide it, and  
seal if from intrusion. It looks real fine!

I used one of these black vinyl cover caps made for SO-239 connectors:
http://www.dxengineering.com/Parts.asp?ID=1159PLID=16SecID=127DeptID=36PartNo=DXE%2DVC%2D0612

You need to cut a cap shorter. Slip it over a wooden rod. Using a  
sharp blade, cut around the cap to make it half the original depth.  
Now fold it part-way back to stretch it, and it will snap tightly over  
the mic socket.

You CW-only guys should really like this.

Re: [Elecraft] Thank you Elecraft reflector group!!!

You're kidding right? I'm pretty new to the ham world and have only observed 
that most on this list are true elmers and gentleman (and ladies).

I feel bad if you've had a bad experience here,but I would think that there was 
a gross misunderstanding or misinterpretation under way here. Don't forget that 
these guys put their advise out there out of the goodness of their heart and do 
not receive compensation for their time.

Maybe you just got advise from someone in a hurry or somewhat distracted so it 
seemed curt but it was well intended.

Chill out - this is a great group of people. I'm sure it is just a non-face to

Like I said, I'm pretty new but if I can help you (or anyone) I will.

Take care  73,

Re: [Elecraft] Dead K2 After nearby power surge

2009-02-11 Thread Don Wilhelm
Fred,

We are 'doubling' with overlapping posts here along with fast paced 
responses.

 From that brief measurement, I think Q3 is the problem - I base that on 
the fact that you measure 8 volts on both D6 and D7.  Just remove Q3 to 
check that theory.  The K2 will receive without Q3 installed, but will 
get mixed up if you try to transmit.
If you get receive and a display with Q3 removed, then a new 2N7000 
should fix it.

BTW, you cannot check a transistor or FET for short/open by making 
resistance measurements - it is just not reliable nor predictable.

Don W3FPR

 Fred,

 In cases like yours, first step is to connect a dummy load to the K2 
 just in case it is trying to transmit - it is not good to enter transmit 
 state without a load on the PA transistors.  If it is a K2/100, remove 
 the KPA100 and connect the dummy load to the BNC antenna jack on the 
 lower rear panel.

 First thing is to check the state of the 8T and 8R voltage rails. Those 
 are easily checked at the anodes of D6 and D7.  If D7 anode has 8 volts 
 on it while D6 anode has zero volts, then the K2 is in a transmit 
 state.  If both D7 and D6 anodes have 8 volts present, power it only 
 briefly while making further checks lest some components overheat.

 If both 8T and 8R are present, you need to check the state of the RX 
 signal at the gate of control board Q4 as well as the TX signal at the 
 gate of CB Q3 - one should be on (about 5 volts) while the other should 
 be off (near zero volts).  If both of these are on, the microprocessor 
 was zapped with the power surge, but if only one is on, the problem is a 
 shorted Q3 or Q4 on the control board.

 73,
 Don W3FPR




   
 Don,

 I pulled the control board again to reset the relays and then reinstalled
 it to make the measurements on D6 and D7.  When I powered the unit,
 Elecraft was again shown and the frequency of 7100 was briefly displayed. 
 When then display went out I measured the anodes and cathodes of both d6
 and d7 and measured nearly zero volts on both. 

 

 I tested the voltages on D6 and D7 anodes again when I powered up.  I had to
 power up twice, but each showed around 7 volts before they fell to near
 zero.  I have found that I can let the unit sit for a few minutes before I
 re-power and I don't have to pull the control board to reset the relays. 
 This only gives me about 2 seconds to make the measurement.
 The voltage on the gate of Q4 is 5 volts.  The voltage on the Gate of Q3 is
 close to zero for the brief period I have to make the measurement.  After a
 few moments the gate of Q4 drops to zero.

  How do I tell which is shorted?  I made the following measurements to
 resistance measurements referenced to ground.

 Q3
   S  - 0.4 M
   G  - 5.4 M
   D  - 8.1 M

 Q4
   S  -  0.3 ohms 
   G  -  3.9 K ohms
   D  -  8.1 K ohms

 I am assuming the culprit is Q4.  Am I correct?  Is it possible the
 something else is fried that may take out Q4 if I install a replacement?  I
 still have 4 boards that I have not built (SSB, DSP2, AT and NB).   I
 believe at least one of these has a 2N7000 I can rob for a temporary
 replacement.  I just don't want to install it until I am sure another
 failure somewhere else upstream won't cause it to fail.  Are there any other
 items I should check before I replace the failed transistor?  

 Thanks,

 Fred

I guess I'll get busy and finish coding the terminal page. :)

Other than a conversation I had with Greg, I don't recall any other Mac users

that no one will use. Now that I know it's wanted, I'll get it done.

In the meantime, for those wanting to work digital modes on the Mac, I HIGHLY

[Elecraft] K3/100 Assembly - KSYN3 Installation

2009-02-11 Thread Walter V. Gilles
Greetings,
 
Ref: K3 Kit Assembly Manual, Rev. F, October 28, 2008.
 
I was just about to install the KSYN3 (ref manual, page 50) when I noticed that 
one pin on P73 on the KSYN3 board is missing.  Looking at the figure on page 
50, it is the third pin from the right, top row. The pin comes off the PCB, 
bends and enters the plastic, but it is missing on the other side (pins that 
insert into J73), close to the plastic portion of the plug.  Just a tiny bit of 
the pin shows, not enough to insert into J73 at all.
 
The manual does not have an OBTW regarding this, nor could I find any 
reference here on this missing pin, and the pictures in the manual, including 
the parts list photo do not reveal a missing pin.  S..can anybody 
please provide the missing clue so I can proceed with confidence or

[Elecraft] K3 and PSK31

OK, Stupid question, I can't believe I can't get this running.

PSK31 operation PC to K3, Digipan (then HRD/DM780 when I get it figured out, 
one thing at a time).

Windows XP pro, Digipan, both signals checked on the comm 1 port for transmit, 
NO Rigblaster, serial cable direct to 1.7 gig PC, sound card on the mother 
board, K3/100 (plus options).

What mode am I supposed to have the K3 in?

1. Data, Data A, vox or not = won't go into transmit.

2. USB mode, goes into transmit and transmits data as expected except that the 
frequency is 600 Hz above the VFO setting and does not follow the waterfall 
frequency.

Works fine on 746 through original Rigblaster, I didn't think it was supposed 
to be needed on the K3.

Re: [Elecraft] K3/100 Assembly - KSYN3 Installation

2009-02-11 Thread Matt Zilmer
Hi Walter, 

Don't know OBTW but on some male connectors unused pins are cut to use
as keys.  I don't recall this being one of them, however.  There is no
easy way to plug the KSYN3 in backwards but it's possible the key is
added to keep the connector from being misaligned   If there is a
keyplug inserted into the matching female pin hole, then this is
certainly a key pin.  

Elecraft doesn't screw up things like this.  Pins 3 and 6 are n/c, so
it's likely your cut pin is pin 3, and it's being used as a key. Check
your schematics to be sure that it's pin 3, then move on.

Oh yes.  Welcome to K3-ness.  You'll feel better shortly.

There are 2 'modes' - the first is DATA mode set by the MODE switch, and 
the second is the type of data mode set by the DATA MD button.

The K3 must be in DATA mode, and to use the paddles for transmit, the 
DATA mode must be set for PSK D (psk31) or FSK D (rtty).

I am not certain how hams like you and Gary would know the correct 
setting for the mode and DATA MD unless you first have a sighted helper

If you're using Data A, make sure the CONFIG:PTT-KEY setting is
correct to actuate TX.  For example DTR-OFF lets the DTR signal key
the TX.  Digipan can accommodate this too.

Data A is a good choice for this.  The K3 is an excellent data radio
and this mode supports PSK31 quite well.

Jim,

Use DATA MD = DATA A.

If you have the K3 set for VOX operation, that should be all that is 
required.
If you choose to use PTT, set the K3 for PTT and select either RTS or 
DTR in the CONFIG: PTT-KEY menu *and* select the same signal for PTT in 
the Digipan application.

I don't normally use Digipan, but I just tried it and it worked FB for me.

know the actual transmit frequency that would have to be calculated by 
the Digipan application rather than the K3 display.

 that the frequency is 600 Hz above the VFO setting and does not follow 
 the waterfall frequency.

Re: [Elecraft] m1-m4 memory buttons

2009-02-11 Thread W0MU Mike Fatchett
To all who responded thanks!

I was missing the M to V step.  For some reason I thought you just hit the
M1 or M2 key and it would pull the memory.  

I have not tried it since all the replies but I am sure that will fix it.

Thanks again.

Mike,

The 0 - 9 buttons are 'quick memories' and are the same as normal memories 0
thru 9.
If you have data stored in the normal memories 0-9, then tapping MV
followed by a tap of the appropriate button should retrieve the memory
contents.

If you want the 0-9 buttons to act like 'band select' buttons, then set the
CONFIG: MEM 0-9 menu to BAND SEL and once settings are stored for any
frequency in a band, those memories will return to the last used frequency,
mode, antenna selection, filter selection on that band.

You can also use the 0-9 buttons to store those memories.  Set up VFO A and
VFO B each with their modes and other settings.  Then tap VM followed by a
tap to one of the 0-9 buttons.  To retrieve, tap MV folowed by a tap to one
of the keypad 0-9 buttons.


The M1-M4 buttons are similar, but are PER BAND.  That means you must select
the band first.  Then you may store or retrieve the memory contents for each
of the 4 buttons.  Tap VM, then tap the M1-M4 button to store.  Tap MV
followed by one of the M1-M4 button to retrieve.

 Ok I read the manual and I have been unable to program the m1-m4 keys 
 or the
 0-9 keys.  I can program a normal memory just fine.  

 Is there a menu setting that I am missing or did I have to do 
 something in the K3 utility program to get this to work?

Re: [Elecraft] Terminal for Mac users

2009-02-11 Thread David Ferrington, M0XDF
I hadn't realised the Mac version didn't have it and it explains a few  
questions in my mind when people said here they had done something, I  
misunderstood what was being done, since I didn't realised the Mac was  
missing functionality.

So David, yes please, do implement the same functionality to the  
highest degree possible in all 3 architectures.

Having this facility for all 3 is quite a big cornerstone in the  
Elecraft arsenal and another reason why the K3 is SO GREAT.

And although not a big user of cocoaModem, I'll second that sentiment,  
Chen puts a lot into his software. And being an ex-Apple engineer, you  
can bet it's 100% cocoa and done 'the right way'. You should look at  
some of the other software there too, all good stuff.

 Other than a conversation I had with Greg, I don't recall any other  
 Mac users mentioning the Terminal. I find it difficult to put much  
 effort into something that no one will use. Now that I know it's  
 wanted, I'll get it done.

 In the meantime, for those wanting to work digital modes on the Mac,  
 I HIGHLY recommend you take a look at Kok Chen's cocoaModem. It is,  
 IMO, the finest digital mode application out there - on any platform.
