Re: [Elecraft] W1SERKT vs KXSER cables

[Jim Rhodes]

I couldn't tell you for sure. My cables have gotten all mixed up. Don't
know what came with which, and they all work as needed. USB, 232 whatever.

Re: [Elecraft] K3 - Persistent channel hopping on a band

[Fred Jensen]

Yes, and Yes, and when I do "M>V", look for memory channel 51, and then 
"M>V" again, it all works as advertised.  If I move to 30 meters, and 
then come back, I have to do the above 3 step sequence to get back into 
channel hopping. Manual says to cancel channel hopping by tapping RATE 
or FINE, which works.  But, if I change bands and then come back, 
channel hopping is canceled even though I didn't tap RATE or FINE.


I don't believe this is a bug.  What I was hoping for was to return to 
channel hopping whenever I go to 5 MHz with the BAND button until I 
cancel it like the manual says.  I'm finding more CW Q's lately on the 5 
MHz channels.


As I said, this is not worthy of a lot of effort, it would just be a 
nice featurette.

Re: [Elecraft] Which interface will the KPA1500 remote app use?

Yeah, I figured it out, and also figured out the NUC I got to sit at the

Now if I could keep the RF out of my RRC, I'd run more than 100W out of

Re: [Elecraft] KXUSB Signal Levels Was: Re: Connecting a KXUSB to the K2 RS232

[ANDY DURBIN]

"but with horrible negative going spikes at each return to zero"

I need to correct that.  The spikes are somewhat random.  For some 
interrogation responses the data word is completely free of negative going 
spikes.  For other responses there are multiple negative going spikes.  When 
the spikes are present they are undershoots and ringing that happens on the 
falling edge of the data.   I have not found any pattern to the occurrence and 
cannot rule out the possibility that it is a measurement artifact.Anyone 
else willing to scope the PC data output of a KAT500?

Any comment or explanation from Elecraft?

[Elecraft] K3 - Persistent channel hopping on a band

Is there a way to to make channel hopping persistent on a given band, 
like 5 MHz?  I can set it up and it works fine, even with the KPOD knob, 
but if I go to another band and then come back, the memory channels have 
reverted back to frequency.  It's no big deal ... M>V, find channel 51, 
M>V again, just wondering if I'm missing something.  The manual tells me 
how to get into channel hopping, it doesn't tell me how to keep it there

Re: [Elecraft] KPA1500 Client/Server Software

The KPA1500 Remote s/w, which should be on our website later this week, supports 
both a local operation via direct connection via USB or ethernet to the amp. 
This s/w also supports client/server operation when there is a computer running 
the K3Remote s/w at each end. (with the same user interface.)


Stay tuned! :-)

KPA1500 at a remote and while the KPA1500 setup utility gets the job done,
it's a poor user experience.

What's needed is a highly graphical client/server application similar to the
type designed by Bernd Koch, DF3CB for the Alpha 87A amplifier.  That
package has client and server components, and the GUI is a high-resolution
graphic of the amplifier complete with switches, LEDs, panel graphics, even
the logo.  Clicking on the GUI is just like finger presses on the actual
amp.  It would be great to utilize the KPA1500's Ethernet port but even
client/server connectivity via USB is fine for now -- just to get something
going other than the KPA1500 setup utility.

I'm willing to help finance the development to get something moving along
now and not some TBD date in the future.

Re: [Elecraft] Thank you to Elecraft

[Michael Blake via Elecraft]

This has been a very interesting thread for me.  I too am a very satisfied 
elecraft customer, mainly as a result of EXCELLENT service.  I have a T1, SG3, 
KX3, PX3, K3s, SP3, KPA500 and KAT500.

When the KX3 was about 10 months old I noticed that a couple of the yellow 
painted letters on the face plate were popping off.  The faceplate was quickly 
replaced. My KPA500 had a very unusual fault in that 4 of the PEM nuts in the 
bottom chassis plate were the wrong thread size.  Once diagnosed the bottom 
plate was quickly replaced I I rebuilt the amplifier.  After about 6 months I 
turned on the station and keyed a couple of “dits” on the paddle and the KPA500 
blew the tops off of both output FETS.  Elecraft quickly had a replacement 
power module on the way to me.

This week I finally figured out that a distorted SSB audio report I received 
since I built the K3s as really present only when using more than 12 watts 
output.  Whenever the KPA3A kicked in there was a noticeable distortion on my 
signal.  You guessed it, a replacement KPA3A module was in the mail and should 
arrive this Wednesday,

Their service is excellent and I am a VERY SATISFIED customer.  My wife’s 
comment, on learning that I was waiting for another replacement part, was “you 
certainly seem to have a lot of problems with that stuff”.

Go figure :)

Oh yeah, I am also a MAC lover :)

Over the years I have owned most everything and dealt with all the

[Elecraft] KXUSB Signal Levels Was: Re: Connecting a KXUSB to the K2 RS232

[ANDY DURBIN]

"can you confirm that the KXUSB uses TTL signal levels rather than standard 
RS232 levels? "

I just put a  scope on a breakout of the signals between a KXUSB and my KAT500. 
 I needed to do this for another purpose anyway.   The simple answer seems to 
be the (my) interface is neither TTL nor RS232 compliant for voltage.  The PC 
out data swings between  0 V and  5 V.  The response data from KAT500 swings 
between  0 V and 9.4 V but with horrible negative going spikes at each return 
to zero. 

Now I don't know if I should interrogate my KAT500 with RS232 or TTL.   I 
certainly can't feed the KAT500 responses to the low level inputs of an 
Arduino.  However, it would seem to be safe to use the KXUSB to interface with 
a TLL compatible device.

[Elecraft] Thank you to Elecraft

[Gary Smith]

Between my recent orders to upgrade my 
Backup K3 and my recent service (update) 
to my K3s which just returned today, I 
want to thank anyone from Elecraft who may 
read this.

My K3s was attended to quickly and 
returned in marvelous condition and thank 
you for the updates. The shipping of the 
items for the K3 was done expeditiously 
and the quality of communication was to my 
estimation, perfect.

To be exact: Every communication I have 
ever had with Elecraft be it from 
reception, orders, tech help, fairness in 
pricing to shipping has been an exemplary 
experience which dates back to my first 
contact in 2008.

I could not ask for more and I am truly 
satisfied with this experience. If 
everyone else provided this quality of 
product and support, I'd never know just 
how good it really is.

I'm just saying.

Re: [Elecraft] KXUSB Signal Levels Was: Re: Connecting a KXUSB to the K2 RS232

[Don Wilhelm]

Mark,

All I can tell you is that the KX2/KX3 and XG3 will respond to input 
levels (on the tip) from 3.3 volts up to the maximum RS-232 voltage.  
The output (ring) from the XG2 is an FET drain connected to a drain 
resistor which connects to +9 volts.  I don't know about the KX2 or KX3.

Re: [Elecraft] Connecting a KXUSB to the K2 RS232

[Don Wilhelm]

Hans,

Does the USB to RS-232 cable have an FTDI chipset?  I know that works OK 
with the K2 (at least the one used in the KUSB).  Others fail with the 
slow 4800 baud rate required by the K2.  I have had good success with my 
Edgeport serial converter as well.  A Prolific chipset adapter may or 
may not work.


You still need to build a cable having only 3 conductors to isolate the 
non RS-232 pins from the serial port, even though it may be short.  The 
AUX IO to PC cable is shown in the KIO2 and the KPA100 manual.

Re: [Elecraft] Connecting a KXUSB to the K2 RS232

[Don Wilhelm]

Hans,

Do not connect a standard serial cable or a USB to serial adapter to the 
K2 AUX IO connector - keep in mind that it is not labeled "RS-232" for a 
reason.


Yes, you can make an adapter to connect the KXUSB to the K2.  A 3.5mm 
jack and a DE9 male connector as well as 3 wires are needed.
Connect the KXUSB tip to the DE9 pin 3, the ring to pin 2 and the Sleeve 
to pin 5.



If you have the QRP K2 and want to really be 'clever', you could mount 
the jack on the rear panel of the QRP top and wire to the back side of 
the DE9 connector pins on the KIO2.  If you have the KPA100, there is no 
room on the rear panel and you will have to build the external adapter.

Re: [Elecraft] Panadapter shift when filter switched in

[Richard Ferch]

Do you have any 5-pole roofing filters? In particular, is your wide filter
a 5-pole 2.7 kHz filter or an 8-pole 2.8 kHz filter? The 5-pole filters
have an offset, which is written on the filter and which is entered into
the firmware with the CONFIG:FLx FRQ menu entry (or by using the K3
Utility). When a filter with an offset is selected, the IF changes by the
amount of the offset. For example, if you have a filter with an offset of
1.0 kHz, then when that filter is selected, the centre of the IF bandpass
is actually moved by 1 kHz relative to where it is when using a filter with
no offset. If your panadapter takes its input from the IF Out port, input
signals will move when you switch the receiver between filters whose
offsets are different from one another.

There is also a per-mode offset between SSB modes and CW, AM or FM. This is
not actually a change in IF frequency, but rather a change in the way the
radio's dial frequency is related to the receiver's bandpass. In CW, AM and
FM, the receiver's bandpass is centred on the dial frequency. In FSK D or
AFSK A, the receiver's bandpass is centred between the mark and space
tones, i.e. 85 Hz away from the dial frequency. In SSB or DATA A, the
receiver's bandpass is centred above (USB and DATA A) or below (LSB) the
dial frequency by approximately half the audio bandwidth (more accurately,
by the DSP filter Fc setting). If the panadapter uses the dial frequency to
label frequencies in the display, simply changing modes will result in a
shift in the displayed signal relative to the frequency markers.

There are a couple of other things that affect the relationship between the
IF Out signal and the frequency displayed on a panadapter. One is the
filter Shift control (or Hi-Cut and Lo-Cut controls) - when the filter Fc
is moved, so is the IF relative to the signal frequency. Another was
mentioned by Wayne in a recent post on another thread: in CW, with some
combinations of sidetone pitch (low) and DSP filter bandwidth (high), the
firmware moves the IF centre frequency to ensure that the low edge of the
audio bandpass stays away from zero. Both of these effects are usually
quite a bit smaller than the mode-to-mode or crystal filter offset
differences, but they can be seen easily enough when you zoom in the
panadapter display.

There is a radio control command specific to the K3/K3S that software and
the P3 can use in order to adjust the frequency display markings to
compensate for these offsets, but generic software like HDSDR doesn't use
that command.

Re: [Elecraft] KAT100 - Reluctant to come on, K2 often displays "not inst"

[Bill Coleman]

I pulled out the KAT100 PIC chip and re-inserted. No change. 

I can confirm that transition ARE reaching Pin 40 on the KAT100 PIC chip. I see 
roughly three bursts. Two come shortly after turn-on, the third comes a second 
later. 

I think you’d need a storage scope or logic analyzer to reverse engineer the 
AUXBUS. I don’t have that kind of equipment available.

Re: [Elecraft] KAT100 - Reluctant to come on, K2 often displays "not inst"

[Bill Coleman]

That’s not the way Elecraft recommends. The KAT100 contains an electronic 
switching mechanism. Power must be present at the KAT100 coaxial connection 
before the K2 is switched on. The KAT100 uses the 12CTRL voltage from the DB-9 
connector to turn on it’s internal supply.
