[Elecraft] noise on SSB modulation

[DK5EW]

Hi all,
I use at my K3 a HEIL PRO SET ELITE "IC", I had this as I use it at my 
old ICOM IC-275H as well.
Now I recognised that I have a small noise on modulation like a fan that 
gives me some power output when I just push PTT.
OK I have in my shack 2 additional fans for cooling the PA so I switched 
them of. The noise is lower but still there.
and there are no other noise sources. So my setting for the HEIL headset 
are:
- MIC: 25
- CMR: 25
- MIC SEL: RP + HIGH BIAS
- MIC+LIN: OFF
Do you have any idea if I can change setting to cancel that noise ?
I can not believe that the microphone is that sensitive to pick up all 
little noises around.
best regards Erwin/DK5EW

It is not a fan, it is RF or other noise getting back into the mic 
circuit.  I had the same problem.  Check the two mods on the Elecraft K3 
Enhancements and Application Notes page.  Look for Older K3 Mods > 
"Front Panel Microphone" and "Improving the Immunity of the real panel 
RS232 and audio connectors" to see if they apply to your rig's serial 
number.  Do both to solve your problem.

Try reducing your compression setting.  I get a noise at 25 also.

Re: [Elecraft] K3 DVR AF Play over air...

Hi Michael,
When I got my DVR I cogitated on how it all work and wrote up an
explanation that helped me understand it. I put it in the KE7X K3 book
and also put it up on

Hope this helps.

Subject: [Elecraft] K3 DVR AF Play over air...

Can anyone tell me how you can playback the K3's DVR AF Play file over
the air?
 
Also when using AF REC and recording a short received clip of audio and
then going to play it back there is a large empty spot (after playing
it) and it  eventually plays a previous audio clip following the one
that was just recorded.  Is this the way it's supposed to work?
 
Thank you,

Re: [Elecraft] KPA500 - Z-Bracket Assembly Question

[Doug VE3VS]

Quote "Finally getting started on Serial 366.  Got to page 22 - attaching the 
Z-bracket to the heat sink.  Using the 5/16" flat head screws all of 
the screws bottom out before the bracket is tight against the heat 
sink.  Has anyone else seen this?  I did double check the screw 
length.  I don't think the bracket should be loose. "

Hmmm! Unusual. Earlier this week I finished assembling #402.  I used
hardware exactly as called for in the instructions. No problem with
assembling the Z-bracket onto the heat sink, nor with fastening the bottom
cover. I was one screw short at one point during the assembly, but simply
used one from the "extras" package to complete the work.

I have been successfully integrating the KPA500 into my station, and giving
it a good workout during the past couple of days.

[Elecraft] [K3] FYI: MCU load failure; K3 not responding error message

[Don Putnick]

I replaced the K3 USB-Serial adapter with a TrippLite  Keyspan USA19-HS 
USB-serial adapter. The MCU firmware loaded the first time. I haven't taken the 
time to troubleshoot the problem, so it would be inappropriate to speculate 
what the root cause was. YMMV.

[Elecraft] K3 Remoting

[GLEN BROWN]

Glad to hear Wayne is thinking about equipment for remote operation.
I was hoping the KX3 would serve as a remote head for the K3.  That would be
perfect for travelling, with the options of either operating QRP, or going
remote.

[Elecraft] QRP Project, Berlin

[Raymond METZGER]

Hi Nigel,

I bought my first Elecraft rig (K2/100) in 2006 from QRP Project in Germany,
since I found their ad in the German Ham magazine "Funk Amateur". This
company has a very friendly and small staff, Peter (DL2FI) and Nikolai
(DL7NIK).
I visited their booth at the Friedrichshafen Hamfest in 2008 and 2010.
During the June 2010 event, Elecraft had its own booth just beneath the one
of QRP Project and Eric presented the P3 for the first time in Europe. 
They also sell kits from other sources. As Peter told me, QRP Project is
also doing repairs and giving support, which may be interesting in terms of
shipping costs for us Europeans.
Their web site is www.qrpproject.de and speaks English and German !

Now, concerning prices, you must take into account that sales from a German
sellers are necessarily subject to the German VAT (I don't remember the
current rate), but you should save some shipping costs.
In France and probably in UK too, small shipments going through the Post
(USPS in the US and your local Post in UK) are not subject to VAT, in which
case, it's better to buy directly from Elecraft than from Germany.. 
Last, but not least, the current GBP/EUR rate has also to be looked at,
specifically within these strange period.

73,
Raymond METZGER, F4FNT

Re: [Elecraft] noise on SSB modulation

[David Gilbert]

If you are using any kind of rig control with your computer (and 
therefore have a shield connection between the K3 and the computer, such 
as via an RS-232 cable), make sure the chassis of your K3 is securely 
bonded to the chassis of the computer with a very short length of large 
gauge wire or section of shielded braid.  I had to go down to less than 
a foot of RG-8 shielded braid to eliminate all hum on my signal.

[Elecraft] Keying KPA500 with K2

[Len Chesler]

I have a QRP K2 that I would like to keep at that power level.  I also have a 
KPA500 that I use with my K3.  I would, however, like to use the KPA500 with 
the K2 w.ithout having to upgrade the K2 to 100W.  Is this something that 
anyone has experimented with?  Tnx. Len

Re: [Elecraft] Keying KPA500 with K2

[Phil & Debbie Salas]

The KPA500 will give you 12-13dB gain.  So your 15-watt K2 will give youi 
200-300 watts out of the KPA500.  I use my KPA500 at 190-200 watts output on 30 
meters when I need a little extra "oomph".  I drive it with about 10 watts with 
my K3.

Re: [Elecraft] noise on SSB modulation

[DK5EW]

Hi all,
I did manage it now by reducing mic and comp so its fine now.
All settings was to much with 25 - now it is 10/15 with the HEIL.
Thanks for fast answer - a good reflector !
I like it !;-)

Re: [Elecraft] noise on SSB modulation

[Martin]

This occurs when CMP and MIC settings are very high, while TX Gate is
set too low.

Maybe an increase in TX Gate level and reducing MIC and/or CMP will cure
the other problem with the transverter.

Re: [Elecraft] KPA500 - Z-Bracket Assembly Question

[Robert Dorchuck]

The holes in the heat sink were definitely not deep enough.  Gary at 
Elecraft Support told me to use the 3/16" flat head screws to attach 
the bracket.  I then used the 5/16 screws for the top cover where the 
length did not matter.  The only other problem was the transfomer 
mounting bolt - it was not threaded all the way.  I was lucky and 
found a bolt at Ace Hardware .  The amp is now assembled and works 
like a champ.

73,  Bob  W6VY

---
Hmmm! Unusual. Earlier this week I finished assembling #402.  I used
hardware exactly as called for in the instructions. No problem with
assembling the Z-bracket onto the heat sink, nor with fastening the 
bottom
cover. I was one screw short at one point during the assembly, but 
simply
used one from the "extras" package to complete the work.

I have been successfully integrating the KPA500 into my station, and 
giving
it a good workout during the past couple of days.

I've tried three different jumpers [the one that came with the P3, and 
two others I'm very sure are good], with no change.  Most of the time, 
the P3 works just great.  I'm pretty certain the case screws/2-D 
thingy's are grounded, I took the pieces off and they all show 
continuity and no paint.

Before cluttering up the list anymore, I'll try to figure out the P3 
Utility and see if I can get a screen capture.  It may take a bit of 
time since this anomaly occurs only infrequently.

[Elecraft] Voltages for Q5 and U8?

[K7MH]

I am troubleshooting a K1 that has no output.
The guide says to check Q5 and U8 voltages but I do not find them listed
anywhere.
The DC voltages table lists U8 pin numbers but no voltages. I see nothing
for Q5.
If anyone knows what they are or where they are listed I would appreciate a
reply.
The receiver works ok and all the voltage and resistance measurements listed
in the
assembly part of the manual and those of U9 Q8 and Q7 are all good.

Re: [Elecraft] Voltages for Q5 and U8?

[Don Wilhelm]

Mike,

I do not know where those DC voltages are listed.  For as long as the K1 
has been out, I don't understand why that omission had not been spotted 
long ago.

However, back to your problem - the quickest path to resolution is to go 
first to page 5 of the manual troubleshooting appendix and build an RF 
Probe (if you have a 'scope with a 10X probe, it can be used instead).  
The RF Probe does not have to be pretty, or shielded or anything like 
that.  If necessary, punch the leads of the components through a piece 
of cardboard to provide support, just connect the leads as indicated.

OK, RF Probe in hand, or 'scope (if using a 'scope, the Expected 
voltages will be shown in peak to peak which are 2.8 times the RMS 
voltages listed), go to the Transmit Signal Tracing section.  What you 
are looking for is the first stage where the RF voltages are 
significantly *lower* than the expected value.  If the voltages are 
higher, that is OK, and is normal for a K1 that is not developing any RF 
output.

Once you have identified the failing stage (the one where the output is 
lower than expected, stop and let us know - we can help with detailed 
analysis of that stage.

[Elecraft] Windows 7 Update, FTDI KUSB and Fluke

[Paul Kirley]

Windows 7 Update advises me that an optional update is available for
"Fluke - Other hardware - USB Serial Converter 706 KB"
Windows says that this update was published "Yesterday", i.e., 9/22/11.

The only USB Serial Converter that I have is the FTDI KUSB purchased 
from Elecraft on last January 26.

Back in April, I got similar updates from Windows, but those updates
included "FTDI" in their descriptions.  As far as I know, my KUSB
worked
fine both before and after those April updates.

I am aware that there have been problems with non-FTDI KUSB cables, and
I would like to avoid those problems.  

Does anyone know if Fluke has taken over FTDI, or is this an update 
that should not be elected?

Thanks and 73,
Paul W8TM

Re: [Elecraft] Windows 7 Update, FTDI KUSB and Fluke

[Grant Youngman]

FTDI is chipset used by a variety of vendors.  KeySpan, Fluke, and others sell 
Rs232 adapters  based on the chipset.  So perhaps your adapter IDs itself as a 
Fluke (brand) adapter.

The Fluke adapter uses the same VID (vendor ID: 0403=FTDI) and PID
(product ID: FT232 USB UART) as the generic FTDI USB serial converter.
In my case the USB port in the SDR-IQ also uses the FTDI default
VID/PID and the "new" Fluke driver (FTDI 2.8.14) was installed for
it.

I suspect the FTDI version of KUSB also uses the default VID/PID

[Elecraft] cw weight reduces as speed increases

[Dale Boresz]

I good friend has kindly lent me his K3. I have noticed that the cw 
weight changes inversely proportional to the speed setting -- just as it 
does on my old K2. The timing sounds decent below about 35 wpm, but once 
the speed gets to around 40 wpm, the weight becomes very light, and the 
keying sounds like it's being generated by a poorly adjusted bug.

I connected up an oscilloscope to monitor the keying envelope while 
sending a string of dits, and it's easily seen that at slower speeds the 
dit length is greater than the space between dits. At around 35 wpm, 
this reverses and the dit length becomes progressively shorter than the 
space between dits.

I would expect that regardless of speed, the dit length should equal the 
length of time between dits. Or, at least the ratio should remain 
constant, and a function of the weight setting.

I also tried to key the radio using an external Logikey K-3 keyer which 
*does* maintain a constant and equal dit-to-space ratio throughout its 
range, but the K3 still shortens the dits as speed is increased.

Is there any way to fix this?

Re: [Elecraft] cw weight reduces as speed increases

[Wayne Burdick]

Dale,

Keying weight would, in an ideal world, not change with speed. But the  
reality is that the low-noise synthesizers in both the K2 and K3 take  
some time to switch between transmit and receive. We take this into  
account, but that can only be done up to a point because of various  
timing relationships in hardware and firmware.

Please try "QRQ" mode, in which the synthesizer doesn't move. This  
allows for far more accurate timing at all speeds.
