I'd like to know a little more about the K144XV receive 
performance.  The Noise Figure is given as 2 dB, while the 
external XV144 has a NF typically 0.8 dB.  This seems like a 
significant difference.  The XV144 also has a high dynamic range

Re: [Elecraft] Right side runs warmer after KRX3 install

One other stupid question... In prep for FD I decided to do some TX
tests...  I found that the radio starts limiting power output and giving
HI CUR messages around 66 to 68C PA TEMP.  I recall Eric stating that
the rig would be fine to 85C.  Is this HI CUR message normal at this
range?  I'm transmitting into a 50 ohm load that is capable of 100 watts
continuous and transmitting at 100 watts.

[Elecraft] K3 Rig Keying/Rig Control with N1MM through microHAM USB CW Keyer

2009-06-19 Thread Gary, VE1RGB
Two direct requests for copies of the following procedure constitute a real
flood of interest in this topic (well, in my books anyway).  

The attached email was the result of me stupidly volunteering my K3 for FD
again this year in the same breath that I boasted about the ease with which
one could implement K3  rig control and rig keying with logging programs,
specifically N1MM.  Never having tried to implement rig keying here at my
fixed station, that was a mistake on my part. .  Looks easy, but not for me.
It took me all day with the assistance of Joe, W4TV, and Richard, VE3KI plus
a couple of local guys, to keep me focused on the important issues to come
up with the following  which, as they say, works for me.  NOTE:  Configuring
the K3 is trivial; my challenge was getting everything to talk to each
other.

I have not yet summoned the courage to close all the programs and shut down
the equipment for fear that I will never be able to recreate success.

Subject: [N1MM] K3 Rig Keying/Rig Control with N1MM and microHAM USB CW
Keyer

Joe, Richard, et al:

Let me be quick to point out that what follows may not
necessarily be either correct or optimum.  There are a couple of settings
that are candidates  for deletion from the procedure.  But I can tell you it
does work
with K3 #095 V3.11/2.15, microHAM USB CW Keyer #120 with Router 4.0.5, and
N1MM V9.3.1.

1. The K3 was connected to the laptop by an Elecraft USB-to-serial adapter
cable which, upon first use, was assigned COM Port 12.

2. Using Device Manager (Properties/Port Settings/Advanced), I manually
reassigned its default COM Port to a low number that N1MM could handle (COM
7).

3. The microHAM keyer is connected to the laptop with its supplied interface
cable from the USB port on the keyer to a vacant USB connector on the
laptop.

4. The keyer is also connected to the K3 Key In line by a cable from the
phono CW jack on the keyer.

5. The K3 is set to 38,400 Baud and the Config Menu PTT-KEY settings are
OFF-OFF.

6. microHAM USB Device Router was used to create a new virtual port. I
chose COM 4.  This step seriously confused me because the new COM Port
showed up in Device Manager, not under Ports (COM  LPT) as do virtual ports
from LP-PAN
bridge, but as a new line item called ELTIMA Virtual Serial Ports. 

7. Router Ports settings, top-to-bottom, are: none; none/DTR; none/DTR; COM
4.
I do not know why it says that COM4 is Open at 1200 8N1.

8. N1MM Configurer/Hardware is selected to COM 4/none, with the CW box
checked, and is set to DTR Always ON; RTS Always OFF.   This is the port
through which rig keying signals, initiated by the logging program, are
generated by the microHAM keyer and sent to the K3.  Also, the Winkey box is
checked.

9. N1MM Configurer/Hardware is also set to COM 7/Elecraft K3/38400 n81/
DTR-RTS OFF-OFF.  COM 7 is the rig control port.

10. N1MM Configurer Winkey Pin 5 is selected to Function PTT.  Don't ask
why.

With N1MM, I now have:

1. Keying via the paddles, speed controlled by the pot;

2. Keying via keyboard, speed controlled by the pot; 

3. Messages on the Function keys that I can change under N1MM;

4. Rig control; and

5.  Control over keying characteristics via the Router control panel.

Here's what I learned:

1. I still do not like computers nor, for that matter, rig
keying.

2. This configuration will not work if one does not first turn
on the router;

The Halifax Amateur Radio Club will be very appreciative of
the contributions of those here on the N1MM reflector who pleasantly kept
after me until, like the proverbial monkey, I managed to strike a sufficient
number of keys and make a sufficient repeated number of mouse clicks that I
eventually wrote N1MM K3 Rig Keying for Dummies.

I now have the station on battery power in case the mains fail,
and I'm working on a plan to get all the hardware, still connected and with
all software running, from here and now to Field Day, without every having
been shut down. After Field Day, I'll start examining some of the above
settings to see whether or not they are relevant, then I am disabling rig
keying and going back to contesting by hand, which is where the real fun is
for me.

Thanks a lot, guys.  Really.

Gary, VE1RGB

Re: [Elecraft] K2 Lo P

2009-06-19 Thread Jay Sissom
Thank you for your help.  I'm at work right now, but will do more
research this weekend.

My friend has had the radio for a couple of weeks and has made
contacts on the radio so it mostly seems to work, but his Lo P message
appears once in a while and I've never seen it on my K2.

I changed the CAL CUR to 3.0 amps and the Hi Current message went away
(I tested 40m and 10m).  But the Lo P message remained most of the
time.  Tonight I'll do more testing with the wattmeter and get more
information to share.

I'll change the CAL CUR to 3.5 amps do the tests you recommend and get
back to you.

 Jay,

 The real answer is it all depends.
 Since this is a very recent K2 serial number, it may be that this problem
 has been present since it was built and was the reason that the original
 builder sold it - that is an unfortunate situation, but it must be
 considered.

 First, set your CAL CUR to 3.50 amps and try again.
 LoP indicates that the K2 is not developing adequate power to enable proper
 tuning for the KAT2 (it needs 2 watts to tune).

 Then set the K2 ATU menu to CALP and see if it will do a TUNE into a dummy
 load - first try at 5 watts power requested, then 10 watts and finally at
 maximum requested power.  Does the HI-CUR message appear at all those power
 levels?  Or only at maximum power?
 Next, try each band separately (doing the tests as above).  Does the HI-CUR
 message appear on every band? or only some bands?

 After those tests, set the ATU menu to AUTO and do a TUNE into the dummy
 load.  You should hear some relays click and after the tuner has set its L
 and C values to match the 50 ohm load, it should exit from TUNE.

 If all that does not produce satisfactory results, there is something wrong
 with the K2.  To troubleshoot it, the first step is to remove the KAT2 and
 operate the base K2 directly into a 50 ohm non-inductive dummy load.  If it
 does not produce good power output without HI Cur messages, then there is a
 problem with the base K2 - likely in the Low Pass Filters or with the T4
 output transformer.  We can help further if we have more specific
 information - what bands fail? what bands work? How much power is really
 produced?

 Don W3FPR

 Hello, I'm helping a friend who purchased a used K2.  The K2 is a

 When tuning with the antenna tuner into a dummy load, sometimes The

 that the radio would draw that much current when tuning into a dummy

 Any info on this would be appreciated.  I'm finishing up the DSP, 160m

Re: [Elecraft] K3 Rig Keying/Rig Control through microHAM USB CW Ke...

2009-06-19 Thread K4IA
Two keys here (pad pun?)

1.  A  USBSerial Cable talks to the K3 and N1MM.  When you first plug one 
in,  the software may assign the K3 a port number higher than 8.  N1MM won't 
 recognize it.  You must re-assign an unused port number to the USB that is 
 8 or less and then use that port number in the N1MM Config Ports menu.  To 
 re-assign a port number look under Control PanelSystemDevice  
ManagerPorts and look for an entry like Prolific USB-Serial Bridge  (Com14).  
Right 
clickPropertiesPort Settings and choose a lower  port number.

Alternatively, with the MicroHam router program, you can  create a port to 
use.  Select Virtual Port in the blue bar of the MH router  screen and then 
Create.  It must unused (check in the Windows Device  Manager to see the 
ports already taken) and be lower than 8.  It will  appear in Control 
PanelSystemDevice ManagerPorts as an Eltima  Virtual Serial Port.  Since the 
port 
is created by the MH program, you  should start MH before you start N1MM.

2.  Keying is done through a  second Eltima Virtual Serial Port you create 
using the MH software.  In the  N1MM ConfigurePorts menu, you select that 
port, radio none, check the CW box  (because this is the port that will 
control CW) and hit the set button.  On  the screen that appears check the box 
WinKey   

When you are  done, N1MM is using two ports - one for rig control and one 
for  keying.

This advice applies to DxLab and I am sure other logging/keying  programs 
as well.  I have found computer keying the K3 through the MH  devices to be 
very reliable and accurate.

Re: [Elecraft] Looking for a good battery/charging system for K1

2009-06-19 Thread Michael Babineau
John :

Here is a few battery suggestions for your portable K1 station.

If you want 5W you will need a 12V+ pack. If you are willing to settle  
for about 3w out the K1 will hum along
nicely at 9 to 10V. It is quite a miserly rig so you can easily manage  
a day outing with battery capacity
in the range of 2 to 3 Ah.

I use a couple of different packs depending on the circumstances.

My suggestions :

1) a small sealed lead acid (aka GEL-Cell) battery in the range of 2  
to 3 Ah
- Walmart also sells a good little charger for SLAs for about $25
   called the EverStart Battery Companion (1.5Amp trickle charger).
   It is actually a 3-stage smart charger perfect for SLAs that are =  
2Ah.

2) 9v (actually closer to about 10.5V when fully charged) R/C NiMH  
battery packs
The Radio Control  packs you should be able to get at Radio Shack  
along with the proper charger.
Radio Shack usually sells a combo pack with a charger (part 23-432)  
for about $20.
These packs are  in the 1500 to 1700 mAh range.
If you go this route I suggest you buy a 2nd pack so you have a  
backup. Another good idea is
to cut the leads on the pack and solder appropriately rated pico-fuses  
on both leads (these
look like resistors) then put heat-shrink tubing over them and tape  
the leads against the body
of the pack with electrical tape (the pic-fuses are a bit fragile so  
you don't want break them).
(Hint, these packs also fit inside a FT-817 and make a good cheap  
internal battery for that rig.)

3) Go with rechargeable AA cells. You can buy 8 and 10 cell holders  
depending on what voltage you
want (note that NiMHs are nominally about 1.2V when fully charged).  
You can find lots of these at  WalMart, Radio
Shack etc, along with 4 cell quick chargers. I would go with a  
reputable name (ie Duracell etc) rather than the
no-name ones and try to buy cells that  are in the 2000 mAh range.
Note that the K1 will tolerate up to about 15V in so you can use a 10  
cell holder if you are using NiMH
rechargables. In practice I have found that a 10 cell holder with  
NiMHs will give 13+ V when fully charged which
is perfect.


For safety reasons, (both yours and the rig) I strongly recommend that  
you fuse whatever battery solution
you decide on and don't forget that you need to be careful with NiMH  
packs as these batteries
can generate a very very high current for a short period of time if  
shorted out. Needless to say this
can result in burns or even an explosion.

Best of luck

Michael VE3WMB / VA2NB

P.S. Another related idea. I standardized my QRP power connections on  
a 2 pin Molex connector (polarized).
Most of my battery packs have a short pigtail with the female version  
of this Molex and I have a slightly longer
length of wire that is fused and has the male Molex on one end and the  
appropriate coaxial power connector that fits into the K1.
This allows me some flexibility in how I power my K1. For instance I  
have a cigarette lighter plug that has the
female Molex so I can use this adaptor to plug my K1 into the  
cigarette lighter jack in my car if I want to operate
  from the car.  For some of my otherQRP rigs like the ATS3 that have  
a different power connector I just made up a fused power cord
that has the male Molex on it so I can use any of the battery options  
that I already have for the K1.
I found that this modular approach works very well.

[Elecraft] RE SDR - May break in the future (was K3 vs. 7600)

2009-06-19 Thread Darwin, Keith
 

-Original Message-
From: Steve, NN4X

That is something which I keep very much in mind with radios like the
Flex, and the idea of PC-dominated radios in general - really, you're
always potentially one Windows update away from breaking the rig.  If
the company goes out of business, or does not feel like supporting an
X-year old, non-current version of their product, you are done.  Over
and out.

--

I'd not thought about that but I think Steve is right on.  A hardware or
self contained rig will continue to work even if the company goes out of
business or the rest of the world around the rig changes.  Once it
works, it always works.  If the company goes away, the rig still works.
The true SW radios (Flex, others?) depend on having the right version of
Windows.  When Windows changes and the flex SW doesn't work, your radio
doesn't work.  So to keep your old Flex running, you have to keep your
old PC running as well.  No upgrades.  And good luck if your 8 or 10 yr
old PC needs to have a part replaced.  Now, think about the value of a
20 year old Flex radio.  Compare that to the value of a 20 Yr old Drake
or Heathkit rig.  One is a rig you can put on the air, the other is
probably a doorstop.

 to 3 Ah
 - Walmart also sells a good little charger for SLAs for about $25
   called the EverStart Battery Companion (1.5Amp trickle charger).
   It is actually a 3-stage smart charger perfect for SLAs that are =
 2Ah.

 2) 9v (actually closer to about 10.5V when fully charged) R/C NiMH
 battery packs
 The Radio Control  packs you should be able to get at Radio Shack
 along with the proper charger.
 Radio Shack usually sells a combo pack with a charger (part 23-432)
 for about $20.
 These packs are  in the 1500 to 1700 mAh range.
 If you go this route I suggest you buy a 2nd pack so you have a
 backup. Another good idea is
 to cut the leads on the pack and solder appropriately rated pico-fuses
 on both leads (these
 look like resistors) then put heat-shrink tubing over them and tape
 the leads against the body
 of the pack with electrical tape (the pic-fuses are a bit fragile so
 you don't want break them).
 (Hint, these packs also fit inside a FT-817 and make a good cheap
 internal battery for that rig.)

 3) Go with rechargeable AA cells. You can buy 8 and 10 cell holders
 depending on what voltage you
 want (note that NiMHs are nominally about 1.2V when fully charged).
 You can find lots of these at  WalMart, Radio
 Shack etc, along with 4 cell quick chargers. I would go with a
 reputable name (ie Duracell etc) rather than the
 no-name ones and try to buy cells that  are in the 2000 mAh range.
 Note that the K1 will tolerate up to about 15V in so you can use a 10
 cell holder if you are using NiMH
 rechargables. In practice I have found that a 10 cell holder with
 NiMHs will give 13+ V when fully charged which
 is perfect.


 For safety reasons, (both yours and the rig) I strongly recommend that
 you fuse whatever battery solution
 you decide on and don't forget that you need to be careful with NiMH
 packs as these batteries
 can generate a very very high current for a short period of time if
 shorted out. Needless to say this
 can result in burns or even an explosion.

 Best of luck

 Michael VE3WMB / VA2NB

 P.S. Another related idea. I standardized my QRP power connections on
 a 2 pin Molex connector (polarized).
 Most of my battery packs have a short pigtail with the female version
 of this Molex and I have a slightly longer
 length of wire that is fused and has the male Molex on one end and the
 appropriate coaxial power connector that fits into the K1.
 This allows me some flexibility in how I power my K1. For instance I
 have a cigarette lighter plug that has the
 female Molex so I can use this adaptor to plug my K1 into the
 cigarette lighter jack in my car if I want to operate
  from the car.  For some of my otherQRP rigs like the ATS3 that have
 a different power connector I just made up a fused power cord
 that has the male Molex on it so I can use any of the battery options
 that I already have for the K1.
 I found that this modular approach works very well.

Re: [Elecraft] Looking for a good battery/charging system for K1

2009-06-19 Thread Paul Christensen
 Here is a few battery suggestions for your portable K1 station.

For several years, I've used various 12VDC gel cells with reasonably good 
success.  To better deal with the voltage drop issue over the course of long 
weekend operations, I've switched to a +14.4VDC portable battery pack from 
Bescor.

http://www.bescor.com/Export8.htm

My K1 and other QRP rigs perform better over the long-term with the slightly 
elevated voltage.  Another option is to use a 12VDC gel cell with a DC-DC 
switching converter as a battery booster to keep battery voltage at or above 
12V as the battery terminal voltage falls below 12V.  I've not been too 
impressed with the RFI immunity from DC-DC converters, so that was not a 
viable option for me.  I'm sure there are some boosters that can be 
purchased with good RFI abatement but for me, that takes too much time in 
testing and evaluating.

Paul, W9AC

[Elecraft] Looking for a good battery/charging system for K1

2009-06-19 Thread Paul Kirley
Before you reach a decision on battery packs, be sure to read Wayne's Tech Note 
at
http://www.elecraft.com/TechNotes/k1_battery_op.htm

Basically, the principle of impedance matching applies to both input and output 
of a rig.  A DC input mismatch results in waste heat, which is usually not a 
problem unless the DC is in limited supply, e.g., from a battery.

My particular K1 tends to drift a bit more when its regulators have to 
dissipate extra DC input voltage as heat.  The second regulators in the K1 put 
out about 6.3V, so an input of 14.3V results in twice as much wasted voltage in 
the regulators as an input of 10.3V, i.e., four times as much wasted heat to 
cause more drift.

For battery supplies, I prefer packs of 8 AA NiMH cells.  Alternatively, I use 
a variable AC supply which I set to 10V (plus an extra 0.3V that doesn't make 
it to the K1's voltmeter).  Either of these supplies matches my preferred 4W 
output setting fairly well, according to Wayne's note.

I retried and did not get past the FPF load. Should I contact K3 support?

73,

 What files are in your firmware folder that contains MCU revision 3.19?  
 
 It should have hfpf0101.hex as well as hmcu0319.hex, hdsp0217.hex,
 haux0217.hex, dtbl0009.hex and tboot7.hex.  The fact that your error message
 says it's trying to load hfpf0100 (.hex) suggests that you've got
 hmcu0319.hex and hfpf0100.hex but not hfpf0101.hex in the firmware folder
 you're loading from.  You need the most recent hfpf0101.hex in the same
 firmware folder that you are loading MCU version 3.19 from.
 
 This is what I mean by mixing.  The beta firmware zip firmware file
 contains a complete set of firmware files. All those files need to be in the
 firmware folder you're loading from.

What about bringing along a couple of diodes to use externally to drop the 
excess voltage until your supply batteries have depleated a bit.  Eliminate 
them one at a time as the voltage drops.  Same result of having the 
longevity of the higher voltage supply and no additional strain on the K1.

Re: [Elecraft] Looking for a good battery/charging system for K1

 Before you reach a decision on battery packs, be sure to read Wayne's Tech 
 Note at
 http://www.elecraft.com/TechNotes/k1_battery_op.htm

That's a good summary of power supply optimization for the K1.  According to 
Wayne's Note, the most efficient use of battery voltage becomes a function 
of one's output power target value - ranging from near 14VDC for full-rated 
K1 output to a bit less than 10VDC for about 3 watts.

Depending on the discharge characteristics of the battery, I imagine most K1 
users would be quite happy starting at a commonly available 12V and allowing 
it to drop down to about 9VDC at the end of portable operations or before 
connecting a spare battery to continue.

[Elecraft] KRX3 ANT input flexibility

2009-06-19 Thread Ken Kopp
I purchased the KRX3 to monitor 6M while the radio is in use
on other bands  I connect a 6M omni antenna to the KRX3
and use the KAT3's #2 antenna to feed a 6M array when
the K3 is switched to 6M.  The resulting diversity receive
-is- impressive!

The as-designed choices to select what antenna is routed 
to the KRX3 is limited (IMHO) and here's my method of 
achieving more flexibility in using the KRX3:

The BNC(F) to TMP(M) cable is installed in the normal manner
and is routed to the area atop the rear of the KRX3.  The cable
from the KAT3 tuner is also routed to the same area.  

I've made a short TMP(M) to TMP(F) extension cable to run 
from the KRX3's TMP(F) input connector to the same area atop 
the KRX3.  This allows me maximum flexibility in what source 
is fed to the KRX3's antenna input by just removing the K3's 
top cover and swapping connections to suit my need.

The board-mounted TMP(F) jacks are somewhat fragile and if 
one attempts to sneak the extension cable into the KRX3's 
jack from above and the shell will likely be expanded, resulting 
in a loose fit.  To keep stress on the jack to a minimum, I secure 
the extension cable to the knurled nut on the top of the KRX3.

It's -much- easier to make the connection to the KRX3 input
jack if the KIO3 panel is removed to allow easy access to the
rear of the KRX3.

Re: [Elecraft] KRX3 ANT input flexibility

2009-06-19 Thread Greg - AB7R
Hi Ken!

How about this option.  TMP cable from KRX3 to a BNC on the back of the radio 
(Use the 
hole for the external ref).  Connect this to the common position of an external 
two-
position switch.  Then run a TMP cable from the KAT3 where the subRX connects 
to the 
BNC for the AUX RF. Connect this to one of the two positions on the switch.  
Now 
connect your 6M Omni receive antenna to the second input.  

Now you can switch between the unused KAT3 input and the Omni antenna you would 
nomally keep connected to the AUX RF input without having to remove the cover.

Better yet...you can get an automatic switch and use one of the DIGOUT lines to 
do the 
switching when 6M is selected.

I will probably do something similar.  I also use an array solutions sixpack 
switch.  
ANT1 feeds one side and ANT2 feeds the other.  This way I can select any of my 
antennas for either antenna input.  I keep the Main antenna set to auto switch 
with 
the KRC2 and the ANT2 position I manually switch to I can try different 
combinations.

Re: [Elecraft] Hi Current K2

2009-06-19 Thread Don Wilhelm
First question is - why are you using 4.045 MHz - that is outside the 
ham band.  Use 3.750 MHz instead.  Similarly, 10.00 MHz should be in the 
range of 10.100 to 10.150 MHz.  Also 25.012 is not a good frequency 
either, use 24.90  That is not likely to change your results with the 
HI-Cur display, but just a comment.

Your receive current draw is about normal - no problem there.

Set CAL CUR to 3.50 amps and try again with the power set to 5 watts.
If the power goes up to a high value (much above 5 watts), there is a 
problem with the power control circuits.

The lack of decent power output on 17 meters and up may be an entirely 
different problem.  Normally Hi-Cur combined with low power output 
indicates a problem in the Low Pass Filter or T4.

Please measure the voltage at the base of Q7 and Q8 during a TUNE.  It 
should be 0.6 to 0.63 volts.

 Let me be quick to point out that what follows may not 
 necessarily be either correct or optimum.  There are a couple 
 of settings that are candidates  for deletion from the 
 procedure.  But I can tell you it does work with K3 #095 
 V3.11/2.15, microHAM USB CW Keyer #120 with Router 4.0.5, and 
 N1MM V9.3.1.
 
 1. The K3 was connected to the laptop by an Elecraft 
 USB-to-serial adapter cable which, upon first use, was 
 assigned COM Port 12.
 
 2. Using Device Manager (Properties/Port Settings/Advanced), 
 I manually reassigned its default COM Port to a low number 
 that N1MM could handle (COM 7).
 
 3. The microHAM keyer is connected to the laptop with its 
 supplied interface cable from the USB port on the keyer to a 
 vacant USB connector on the laptop.
 
 4. The keyer is also connected to the K3 Key In line by a 
 cable from the phono CW jack on the keyer.
 
 5. The K3 is set to 38,400 Baud and the Config Menu PTT-KEY 
 settings are OFF-OFF.
 
 6. microHAM USB Device Router was used to create a new 
 virtual port. I chose COM 4.  This step seriously confused me 
 because the new COM Port showed up in Device Manager, not 
 under Ports (COM  LPT) as do virtual ports from LP-PAN 
 bridge, but as a new line item called ELTIMA Virtual Serial Ports. 
 
 7. Router Ports settings, top-to-bottom, are: none; none/DTR; 
 none/DTR; COM 4. I do not know why it says that COM4 is Open 
 at 1200 8N1.
 
 8. N1MM Configurer/Hardware is selected to COM 4/none, with the CW box
 checked, and is set to DTR Always ON; RTS Always OFF.   This 
 is the port
 through which rig keying signals, initiated by the logging 
 program, are generated by the microHAM keyer and sent to the 
 K3.  Also, the Winkey box is checked.
 
 9. N1MM Configurer/Hardware is also set to COM 7/Elecraft 
 K3/38400 n81/ DTR-RTS OFF-OFF.  COM 7 is the rig control port.
 
 10. N1MM Configurer Winkey Pin 5 is selected to Function PTT. 
  Don't ask why.
 
 With N1MM, I now have:
 
 1. Keying via the paddles, speed controlled by the pot;
 
 2. Keying via keyboard, speed controlled by the pot; 
 
 3. Messages on the Function keys that I can change under N1MM;
 
 4. Rig control; and
 
 5.  Control over keying characteristics via the Router control panel.
 
 Here's what I learned:
 
 1. I still do not like computers nor, for that matter, rig keying.
 
 2. This configuration will not work if one does not first 
 turn on the router;
 
 The Halifax Amateur Radio Club will be very appreciative of
 the contributions of those here on the N1MM reflector who 
 pleasantly kept after me until, like the proverbial monkey, I 
 managed to strike a sufficient number of keys and make a 
 sufficient repeated number of mouse clicks that I eventually 
 wrote N1MM K3 Rig Keying for Dummies.
 
 I now have the station on battery power in case the mains 
 

[Elecraft] K3 -- DVR question

2009-06-19 Thread Joel R. Hallas
I recently added a digital voice module to my K3. It does everything it is
advertised to do, and does it very well. 

One question occurs to me. The off the air recording feature is a real plus
and will be handy. Is there any way to extract a useful digital copy of the
recorded audio in a way that would be downloadable to the connected PC and
then stored in an easily recoverable way? 

I know the audio could be resampled and stored using a sound card and PC
software, but that would add another A/D conversion. It would be nice to be
able to send someone the original data as a PC file of the way they sound,
rather than sending it over the air.

[Elecraft] K3 Rig Keying, etc - A Caution

2009-06-19 Thread Gary, VE1RGB
Now that he has seen what I have done, Joe W4TV tells me that this is an
incorrect configuration because it completely bypasses the things you get
from MH Keyer, like CAT and PTT.  Of course he is right.  What I have not
made clear to everyone is that my solution is specific to our Halifax
Amateur Radio Club Field Day 2009 CW tent.  It's a repeat of the
configuration we had used, very successfully, with my K3 and Writelog the
year before.  Only this year, same K3 #95 but new contesting software being
used by skilled N1MM/CW ops.  We don't need anything out of MH Keyer or the
system other than its stable rig keying capability and feedback on band
changes from the radio.  So, my solution is specific to that situation, no
more/no less and, as I have pointed out elsewhere, a one-off favour to the
Halifax Amateur Radio Club assembled from what I had available to me.  Since
nothing has gone up in smoke, I'm kinda' proud of it:)

Plse all be QRV for VE1FQ.  This is our new AR station and there
will two firsts this year: first time HARC has ever used its new station in
a contesting environment.  This will be a deliberate exercise in due
diligence by proving out the station because of its strategic value to the
community.  It will also be the first time we will have had, because our new
facilities have allowed for the antenna, the use of top band in a FD.  FD is
a deadly serious business here.  We will be in the F class because our
station has been designated by our local EM Organization that we were to act
as their official back-up communications site while theirs is down for
renovation.  This has been blessed by ARRL.  

Summary:  Remember VE1FQ; and, caveat emptor.

73,
Gary, VE1RGB

Re: [Elecraft] K3 Load fails

2009-06-19 Thread Paul Ferguson
Dick,

Thanks. You were correct about the problem. I have a short (3 ft) extender 
cable connected to the KUSB cable. The junction between the two was slightly 
loose. I tightened it and loaded OK.

I suspected the K3 because the MCU load always worked. It must be that the FPF 
load exercised the data lines differently enough to show up the problem.  

Thanks to you and others for the help.

K5ESW

 It sounds like you can eventually load, although there is evidence of
 substantial communications corruption.  
 
 What sort of cable do you use between the PC and the K3?  USB?  Hubs
 involved? Is it screwed down at the K3 end?  If you have alternate cables
 available, could you try one of those?  If you have several USB ports on
 your computer, could you try a different one?

[Elecraft] OT - CQ Magazine article

2009-06-19 Thread Ken Kopp
The July issue of CQ has an article on page 61 entitled 
The Joy of Kit Building.  I had hoped to see another
article about building an Elecraft kit like they recently
ran, but other than the K1EL kit used as an example in 
the article, nothing that applies to Elecraft kit building.

What -is- shocking is the Weller gun depicted in the
photos and the lack of caution about proper care of IC's
during the process.

I doubt if there are any (?) Elecraft kit builders that would
use the practices suggested in the article, but 

The article shouldn't have made it past the editor's desk.

Glad to hear that things are going well now.

Sometimes these things are data dependent and timing can play a role  
as well.

It is counterintuitive, but success with one type of transfer does not  
always imply success in all types. Data transfer testing can be very  
diffficult. We have some algorithmic plans that may improve this over  
time, but if the data is getting scrambled we're doing well to just  
reliably detect it!

Re: [Elecraft] K3 Rig Keying/Rig Control with N1MM through microHAM USBCW Keyer

2009-06-19 Thread Gary, VE1RGB
Joe:

I may have done you an un-intended disservice.

Just so there is no confusion, this anecdote is supposed to be
somewhat self-deprecating (or did people really think I was going to keep
power on the station until FD?).  None of my problems are to be construed so
as to reflect badly on any of the tools I used in that exercise.  Rather, it
was own lack of even the most basic understanding of what I was doing or
lack of understanding of the language in that environment that lead me to go
around in circles.  Also, if you are playing with a system dependent upon
virtual ports, you have to learn to open the program that creates them
first.  That sort of just basic stuff.  I don't like computers.  It's a
complex tool. It was my first time. Lots of excuses.  Easy, now that I
understand how it works.

With the benefit of hind-sight, perhaps I shouldn't have put
materiel into the public realm without further clarification, since I wasn't
using MH Keyer to its full advantage or traditional role.  But it does work
great the way it's being used.

This may not be what you want Matt, but for small portable radios I use 
a two-pack of heavy-duty 6V lantern batteries wired in series.  These 
are usually right around 5 bux at WallyWorld and last for quite a 
while...several extended outings.

I don't remove the plastic wrap holding the two batteries 
together...just melt the wrap around the spring terminals with the 
soldering iron(so it doesn't split).   Then I cut the springs down to a 
couple of turns and solder the wires/jumper on using my fav connector. 
For the finale...wrap the whole works up in a layer or two of...you know 
it...duct tape...to protect the exposed terminals and make a very solid 
package.  You probably shouldn't try going thru airport security with 
this if you don't have a little extra time...  When the batteries drop 
below usefulness I simply remove the tape/wiring harness and start over 
again.

Re: [Elecraft] K3 -- DVR question

2009-06-19 Thread Lyle Johnson
Hello Joel!

 I recently added a digital voice module to my K3. It does everything it is
 advertised to do, and does it very well. 
 
 One question occurs to me. The off the air recording feature is a real plus
 and will be handy. Is there any way to extract a useful digital copy of the
 recorded audio in a way that would be downloadable to the connected PC and
 then stored in an easily recoverable way? 

I am not hopeful this can be done on a practical basis. The logic would 
be pretty convoluted.  We'd have to snatch a small sample from the DVR 
Flash, then buffer it in the DSP, then push it out the serial port to a 
PC, which would need an application written to slurp up the RS232 data. 
  After many iterations we could get the data across.  The PC would then 
need a program to convert the data into some sort of recognizable, raw 
samples.  I suspect a .WAV file is the most likely wrapper that could 
then be put around it.

Thus, it requires MCU code for the K3, plus DSP code, plus a PC program.

 I know the audio could be resampled and stored using a sound card and PC
 software, but that would add another A/D conversion. It would be nice to be
 able to send someone the original data as a PC file of the way they sound,
 rather than sending it over the air. 

I suspect resampling would add very little noise compared to the radio 
link.  I suspect this is the best bet, again on a practical basis.

Sorry I can't be more positive :-(

[Elecraft] elecraft kat1

2009-06-19 Thread E Neubauer

Hello: I have noticed that my k1 (with the kat1) seems to have difficulty 
obtaining a low SWR with most of my antenna efforts.  Most of the time, it 
stays at 4:1 or higher.  I have been successful at obtaining 1:1, but it is 
kind of hit-or-miss and only works for one band.   I live in a townhouse, so 
options aren't great, but I've mostly tried long wires and loops in the attic 
and yard.  Still, I thought obtaining a decent match wouldn't be so hard, 
especially on 40 meters.  I should note that I have the 2-band filter board for 
40  80 meters.
Also, I am new to ham radio, so I am not sure whether it is safe to operate the 
rig when the SWR is that high.  Comments or suggestions appreciated.

Re: [Elecraft] elecraft kat1

2009-06-19 Thread Don Wilhelm
Ed,

The KAT1 (and most other similar tuners) do have a difficult time 
matching to a high impedance.  So if you stay away from end fed antennas 
that are a multiple of a half wavelength long, the KAT1 should be able 
to match it.  Similarly, extremely low impedances may be difficult to match.

You might try adding or subtracting some length to your feedline.  I 
would suggest starting with a 1/8 wavelength at the frequency that is 
giving difficulty.

Try to get the SWR down to 2:1 or less.  While the K1 probably will not 
be damaged, the power output will go down dramatically with a larger 
mismatch.

Ed,

One other thing - if your match varies from time to time, look for bad 
connections in your antenna system.  An intermittent connection can 
allow good tuning one time and poor results at another time.

Re: [Elecraft] K2 Lo P

2009-06-19 Thread Jay Sissom
Don ( list),

I started doing some testing tonight and have narrowed it down.

I took out the antenna tuner and tested each band at the 2W setting,
5W  10W setting on the power knob.  I have an external watt meter and
dummy load attached.  The power didn't match exactly on all the bands
but it was fairly close (between 1.9W - 3.5W on 2W setting, 4.9 - 7W
on 5W setting and 9W - 10W on the 10W setting).  My Oak Hill WM2
meter only goes up to 10W.

Then I re-installed the antenna tuner and started the test again.  I
connected to Ant 1 and had the ANT setting set to CALS.  On 28060 the
2W setting measured 2W on the meter but gave an SWR of 1.4.  At 5W it
was SWR 1.5 and at 10W it was SWR 3.  The other bands were similar.
When I got to 21060 at 10W, the display said Hi Cur then showed an SWR
of 3.  At 10106 with 10W, it also said Hi Cur then the radio shut down
and wouldn't come back on.  I don't smell smoke or anything so I'm
assuming the fuse reset and I'll need to wait for it to cool down.

So it is definitely a problem with the antenna tuner.  I think this
has already identified a problem and I shouldn't keep going with this
test.  I'll take the antenna tuner out of the lid and look at it in
more detail.  But of course, any other ideas would be appreciated.

Thanks  73

 Jay,

 The real answer is it all depends.
 Since this is a very recent K2 serial number, it may be that this problem
 has been present since it was built and was the reason that the original
 builder sold it - that is an unfortunate situation, but it must be
 considered.

 First, set your CAL CUR to 3.50 amps and try again.
 LoP indicates that the K2 is not developing adequate power to enable proper
 tuning for the KAT2 (it needs 2 watts to tune).

 Then set the K2 ATU menu to CALP and see if it will do a TUNE into a dummy
 load - first try at 5 watts power requested, then 10 watts and finally at
 maximum requested power.  Does the HI-CUR message appear at all those power
 levels?  Or only at maximum power?
 Next, try each band separately (doing the tests as above).  Does the HI-CUR
 message appear on every band? or only some bands?

 After those tests, set the ATU menu to AUTO and do a TUNE into the dummy
 load.  You should hear some relays click and after the tuner has set its L
 and C values to match the 50 ohm load, it should exit from TUNE.

 If all that does not produce satisfactory results, there is something wrong
 with the K2.  To troubleshoot it, the first step is to remove the KAT2 and
 operate the base K2 directly into a 50 ohm non-inductive dummy load.  If it
 does not produce good power output without HI Cur messages, then there is a
 problem with the base K2 - likely in the Low Pass Filters or with the T4
 output transformer.  We can help further if we have more specific
 information - what bands fail? what bands work? How much power is really
 produced?

Here's an update.  When the radio wouldn't come on after typing the
email, I was worried.  I found out my cigar adapter plug from Radio
Shack has a 2A fuse in it and it was blown.  So that would explain why
the radio wouldn't come back on!  With my other power wire, I should
be back in business.

Hi gang,

The weekly Elecraft SSB net will meet Sunday, 6/21/09 at 1800Z. The net will
start at 14.316 MHz, and QSY if needed.  I will not be able to be there, but
Mark, K4SO, in Virginia will be doing the net control duties.  Let's hope
conditions are better than last week.  Have a good one.

[Elecraft] DSP and IF Filters

2009-06-19 Thread Ron Edmon
I have been going through the manual on the K3 trying different combination
of DSP and IF as well as NR filters trying to reduce atmospheric noise.  I
find the noise level to high pitched which fatigues me after an hour or so
of listening.  I've listened to the Hear It external DSP filter employed
on a friends ten-tec rig and the reduction of atmospheric noise is
significant (1 S unit or better).  Shouldn't the K3 DSP filter be capable
of reducing the atmospheric noise to acceptable levels?

Re: [Elecraft] elecraft kat1

2009-06-19 Thread Ron D'Eau Claire
Hi Ed:

I don't have a K1, but I agree with everything Don said. 

Your situation sounds a bit strange though, because I know a number of
people who have K1's who typically have not problem loading all sorts of odd
end fed wires.

You are right to get rid of the coax in almost any situation like that. Coax
has huge losses at high SWRs. The ATU only ensures a match between the
antenna where it connects to the rig and the finals in your K1. It does
*nothing* to reduce the SWR on the feed line between the rig and antenna. 

A counterpoise is used to produce a low impedance at the rig. It's usually
1/4 wavelength long. A 1/4 wave long conductor with the far end insulated
will show a low impedance at rig end. It can replace an extensive RF
grounding system, although a simple one-wire counterpoise is seldom as
effective. However, it's world's better than no counterpoise or ground at
all. Having a counterpoise or RF ground does two things: 1) It keeps
troublesome RF voltages off of the case of your K1, the key, etc. 2) It
greatly increases the efficiency of the radiator (antenna) when the antenna
is an odd multiple of 1/4 wave long or less than 1/4 wave long.

You'll want two counterpoise wires for your setup: one 66 feet long (1/4
wavelength on 80) and one 33 feet long (1/4 wave on 40). You can connect
both in parallel to the case or ground lug on your K1 and leave them
attached at all times. They won't interfere with each other. Indeed, you can
run the two wires alongside each other but separate them the last several
feet and be sure the ends are insulated from each other and from other
objects.

Re: [Elecraft] elecraft kat1

2009-06-19 Thread E Neubauer

Ron:
Thanks for the information about the counterpoise and feedline.  Would using 
300 ohm twinlead work better than coax for a kooky attic dipole I constructed? 
With RG-6 coax and no ground, it seems to work fairly well on 40 meters.
I have a couple of other antenna questions:
Grounding:  I am currently using the third prong of my electrical socket for 
that.  It is connected to the house plumbing in the basement.  Is this 
acceptable?  Should I use this for dipoles and loops, as well as long wires?
Reception:  I have made a couple of contacts in VA and IN with folks who give 
me an RST of 599.  In both cases, their signal was fair  - around 478 at best, 
but drifting.  I was wondering why there is such a difference. Isn't 
propagation usually a two-way street?
Thanks.

[Elecraft] [K3] K3 Utility and Safari 4.0.1

2009-06-19 Thread W7TEA

When I attempted to download the latest beta using Safari on OS 10.5.7
the process stuck after loading 2 of 3 items.  Switching to Firefox was
successful.  This happened some time back and I couldn't find the response.

Re: [Elecraft] elecraft kat1

2009-06-19 Thread Don Wilhelm
Ed,

Actually counterpoise is a misnomer.  When implemented, it is a part 
of the antenna system.  Yes, a 1/4 wave 'counterpoise' will produce a 
low impedance at the shack end, and will tend to keep RF-in-the-shack 
problems to a minimum.

A coax feedline for multi-band operation is not the best - use coax only 
for resonant antennas and use parallel conductor feedline for 
non-resonant antennas.  In the case of an attic antenna, the use of 
'counterpoises' may be necessary because the antenna energy can be 
present in the shack due to the close coupling.

Good luck on your camping adventures with the K1.  An 88 (to 135) foot 
radiator center fed with 300 or 450 ohm parallel line will serve you 
well on both 80 and 40 meters.  Hang it as a dipole or as an inverted 
Vee.  Use a 44 ft to 66 ft length for 40 meters only.

Don W3FPR

 Thanks for the advice.  I will definitely try those things, especially for my 
 attic system.  Just a few moments ago, I got rid of my coax feedline 
 altogether and plugged my antenna wire (long wire to the backyard) directly 
 into the K1, via a paperclip.  Wow, that made a big difference - got down to 
 about 1.5:1 on both 80m and 40m.
 By the way, I have read things about using a _counterpoise_.  Is this a sort 
 of substitute for a ground connection?  I am interested, because we are going 
 to do some camping over the next couple of weeks and I am taking the K1 along 
 for (hopefully) some outdoor work.

Re: [Elecraft] K2 Lo P

2009-06-19 Thread Don Wilhelm
Jay,

It really sounds as though you have a problem with the wattmeter in the 
KAT2.
Try balancing and calibrating the wattmeter again.  If you cannot 
achieve a good null with a good 50 ohm non-reactive dummy load, check T1 
and its associated components (T1 for well tinned and soldered leads and 
C34, R3, R4, D1 and D2 for god soldering and proper orientation).

If you cannot achieve a good null when balancing the wattmeter, stop and 
ask for specific help.  The null is a pre-requisite to proper calibration.

 Don ( list),

 I started doing some testing tonight and have narrowed it down.

 I took out the antenna tuner and tested each band at the 2W setting,
 5W  10W setting on the power knob.  I have an external watt meter and
 dummy load attached.  The power didn't match exactly on all the bands
 but it was fairly close (between 1.9W - 3.5W on 2W setting, 4.9 - 7W
 on 5W setting and 9W - 10W on the 10W setting).  My Oak Hill WM2
 meter only goes up to 10W.

 Then I re-installed the antenna tuner and started the test again.  I
 connected to Ant 1 and had the ANT setting set to CALS.  On 28060 the
 2W setting measured 2W on the meter but gave an SWR of 1.4.  At 5W it
 was SWR 1.5 and at 10W it was SWR 3.  The other bands were similar.
 When I got to 21060 at 10W, the display said Hi Cur then showed an SWR
 of 3.  At 10106 with 10W, it also said Hi Cur then the radio shut down
 and wouldn't come back on.  I don't smell smoke or anything so I'm
 assuming the fuse reset and I'll need to wait for it to cool down.

 So it is definitely a problem with the antenna tuner.  I think this
 has already identified a problem and I shouldn't keep going with this
 test.  I'll take the antenna tuner out of the lid and look at it in
 more detail.  But of course, any other ideas would be appreciated.

 Thanks  73

 Jay,

 The real answer is it all depends.
 Since this is a very recent K2 serial number, it may be that this problem
 has been present since it was built and was the reason that the original
 builder sold it - that is an unfortunate situation, but it must be
 considered.

 First, set your CAL CUR to 3.50 amps and try again.
 LoP indicates that the K2 is not developing adequate power to enable proper
 tuning for the KAT2 (it needs 2 watts to tune).

 Then set the K2 ATU menu to CALP and see if it will do a TUNE into a dummy
 load - first try at 5 watts power requested, then 10 watts and finally at
 maximum requested power.  Does the HI-CUR message appear at all those power
 levels?  Or only at maximum power?
 Next, try each band separately (doing the tests as above).  Does the HI-CUR
 message appear on every band? or only some bands?

 After those tests, set the ATU menu to AUTO and do a TUNE into the dummy
 load.  You should hear some relays click and after the tuner has set its L
 and C values to match the 50 ohm load, it should exit from TUNE.

 If all that does not produce satisfactory results, there is something wrong
 with the K2.  To troubleshoot it, the first step is to remove the KAT2 and
 operate the base K2 directly into a 50 ohm non-inductive dummy load.  If it
 does not produce good power output without HI Cur messages, then there is a
 problem with the base K2 - likely in the Low Pass Filters or with the T4
 output transformer.  We can help further if we have more specific
 information - what bands fail? what bands work? How much power is really
 produced?

 Hello, I'm helping a friend who purchased a used K2.  The K2 is a
 serial number 6xxx with a KAT2, KSB2 and KBT2.

 When tuning with the antenna tuner into a dummy load, sometimes The
 message Lo P appears on the display.  It would also give the Hi
 Curr message with the current limit set to 2.5A.  Does it seem right
 that the radio would draw that much current when tuning into a dummy
 load?

 Any info on this would be appreciated.  I'm finishing up the DSP, 160m
 and KNB2 options for the radio but would like to get this fixed before
 making changes.

[Elecraft] SPL N/A with everybody on CW?

2009-06-19 Thread Brett Howard
Right now I've got VFO A on 14.030.00 and VFO B on 7.027.00 and I'd like
to transmit on the VFO B freq.  Or I'm trying to setup N1MM so that when
I click on the VFO B log section that it switches on split so that I can
TX in the right band.  But I keep getting SPL N/A.  I even then tapped
A-B twice and then went back to those frequencies and still got SPL
N/A.  Seems like I'm unable to use the split and TX on VFO B if I'm on
independant bands?  And yes both are set to CW.

Any ideas what I'm doing wrong?

I should also state that I swear this was just working a minute ago and
now I seem to always get SUB N/A unless both VFO's are on the same band.

I didn't have any trouble on 4.0.1.  But I don't download the files  
directly with Safari.   If you add a / to the end of the URL, the  
Beta directory links as a read-only drive.  It's then a simple matter  
to copy out the files.
