Re: [Elecraft] Sorta OT - assistive technology assistance

[Richards]

THANK YOU for the several replies to my mixer circuit question - both on 
and off the list.  Unfortunately, few actually answered the original 
question,  most often advising me to abandon the project or mix on a 
computer sound card.


First - Thanks, Steve, for your input based on personal experience.   
While I am familiar with your mixer, Tom prefers a device with stereo 
channels and outputs for both headphones and powered speakers. The model 
under consideration has only two control pots, making it easier to 
manage.   Tom truly appreciates your personal input and direct 
correspondence off list.   He puts a lot of stock in your take.


Second - Tom prefers a simple hardware solution.   Locating a manual 
control next to the rig is much easier (for him) to manage, than mixing 
with a computer sound card.   Navigating multiple operating system 
windows is a serious challenge because he cannot see the monitor or use 
a mouse.  This is not the preferred method for a contest or snagging 
rare DX before a pileup ensues.  Mixing on a computer would be very 
inconvenient;  close your eyes and try it some day!   It's easy for you 
to say ... but, not so easy for my friend to do.


Third -  We can simply purchase a commercial product  (I recommend the 
Rolls MINImix MS22s stereo mixer, with just two pots, and outputs for 
both headphones and speakers)


UNFORTUNATELY, THAT DEFEATS THE WHOLE POINT BEHIND MY QUESTION.

While I do NOT wish to look a gift horse in the chops, or appear 
ungrateful for the advice received so far;  money is not the object as I 
want to LEARN how this type of circuit works, and do a favor for a 
friend, in one stroke. Advising me to save money and just buy a 
turn-key, off-the-shelf solution hardly fits the HAM RADIO TRADITION of 
experimentation and self-determination,  and teaches me nothing about 
circuit design.   I was hoping to build something MYSELF- earning that 
heady sense of self-satisfaction that accompanies the completion of a 
successful home brew project.  Considering all the experts on this list, 
including world class board certified AES audio man Jim Brown, I figured 
a simple summing circuit would be a snap.


I close this thread with a big THANK YOU on behalf of my  ... um ... 
"client,"  whilst I repair to the proverbial drawing board to renew my 
search for a simple summing circuit.


Happy trails to all.   JR

(We return you to your regular daily programming content)     ;-)

[Elecraft] New DSP features?

[Wayne Burdick]

Hi all,

The K3/K3S and KX2/KX3 are SDRs, by definition, because they provide 
demodulation and modulation features via a DSP chip that is programmable.

Our DSP algorithms already give the user all the usual features expected of an 
all-mode transceiver, and then some:

  - DVR
  - variable passband filtering & IF shift
  - audio peaking filter (APF, for CW)
  - auto-spotting and automatic tuning (CW, PSK)
  - dual watch (KX2/KX3)
  - audio effects
  - DTMF (KX3)
  - dual-passband filtering for RTTY
  - FM subaudible tones
  - data decode/encode in various modes
  - noise reduction
  - RX and TX EQ
  - synchronous AM (K3/K3S)
  - ESSB
  - transmit noise gating
  - speech compression
  - manual notch filtering
  - autonotch

...etc.

That said, here's your chance to dream up *new* DSP features we haven't thought 
of. All suggestions will be debated by our engineering team, even those that 
appear radical or implausible at first glance. 

We'll keep this to ourselves, so don't worry about being judged for tossing out 
some wacky ideas. Let's cast a broad net.

Please send all correspondence on this topic directly to yours truly.

73,
Wayne
N6KR

Re: [Elecraft] whats a updated K3 called?

[AB4IQ]

I also added the KIO3B modification to my K3 (2197) in addition to the
synthesizer, DVR and TXCO so it operates just like my K3S's.  The only
difference is on the Keypad 6 which says DUAL PB on the K3 and APF on the
K3S that I can see.

Re: [Elecraft] KAT3A & KIO3B Upgrade for my K3

[Don Wilhelm]

There is no access to FSK-D using CAT commands other than those 
supplying ASCII strings.


FSK-D can transmit using paddle (not straight key) input, ASCII text, 
the FSK pin on the ACC connector (with a one transistor keying 
interface) or from the Terminal screen of K3 Utility.


I do not know of any software applications that support other than 
keying the FSK pin (except for K3 Utility).


If you can deal with soundcards, AFSK-A is usually a better choice for 
RTTY.  Many software applications support it.


If you want to use FSK-D, you will have to suffer with the extra cables, 
and with the advent of the KIO3B interface, it is more difficult to use 
the RTS or DTR RS-232 signals from the computer.  You might be able to 
pick those signal off the RS-232 dongle that comes with the KIO3B, and 
run it through the One Transistor keying interface to activate the ACC 
connector pin, but if you have the P3 connected with the K3S and using 
the P3YCBL, getting access to that RS-232 signal becomes more difficult. 
 A standard RS-232 "Y" cable may make it possible.

I've attempted to configure MMTTY to run FSK with my K3S.  Conclusion is that a 
Terminal unit will be required.  Using AFSK is easy and I don't find any 
disadvantages.   No additional hardware required.

Re: [Elecraft] ERR TXF

[Bob McGraw K4TAX]

Normal for most radios due to carrier frequency and receiver offset for CW.  
Elecraft is not the only that does it this way. 

As filters with reduced bandwidth we find that group delay increases. With this 
CW wave shapes become a difficult task.  Wider filters are much easier to 
generate good quality CW elements.

Re: [Elecraft] ERR TXF

[Don Wilhelm]

John,

No mystery - the stock K3/K3S includes the 2.7kHz filter or the 2.8kHz 
with the upgrade.  So CW transmit has to work with that filter - the DSP 
does the rest.


So if you select a CW width filter for CW transmit, you will get the ERR 
TXF message.

For goodness sakes, give up on the CONFIG menu in the radio and use the 
utility. It’s so much easier and you can see all the filters at once.

Re: [Elecraft] KAT3A & KIO3B Upgrade for my K3

[Nr4c]

None that I know of.  FSK is not normally a CAT control nor is it done with 
“handshake” signals on standard serial port. It is passed on the TX line of a 
RS-232 serial connection to a discrete pin on a radio for FSK signaling. My K3 
has such a pin on the Acc2 connector on the rear of the radio. My IC806MkIIg 
also hat an FSK pin on the 13 pin DIN connector. Other rigs are similar. 

AFSK today is not what it used to be. Manufacturers have developed better TX 
and RX filters and I don’t really think you can tell the difference.

Re: [Elecraft] ERR TXF

[Don Wilhelm]

Mark,

Use K3 Utility, it is quick and easy.  Only enable one filter for for 
transmit on each mode.  You can enable multiple filters for receive on 
each mode.


K3 Utility makes it quick and easy - just check off the applicable boxes 
and save to the K3/K3S.

Re: [Elecraft] ERR TXF

Mark,

It is easy to set up the filter enables for each mode - for both 
transmit and receive using the K3 Utility Configure Filters selection.

Save the filter configuration to the K3 and operate.
Much easier than trying to set them for each mode in the menu.

Re: [Elecraft] ERR TXF

[Victor Rosenthal 4X6GP]

This error is caused by selecting a filter other than the 2.8 or 2.7 kHz 
filter as the transmit filter. Use CONFIG:FLTX to select that filter for 
CW/DATA/SSB. (Except if you have FM (13 kHz) or AM filters (6 kHz) you 
must select those filters in the FM and AM modes).

Re: [Elecraft] KX3, QRP, /P, 80m, daylight

[Ken Roberson via Elecraft]

 

Joe,

Testing propagation on 80M in the daytime is a good project.

Often I test propagation on 630M in the daytime with a shortvertical.

A “ T “ antenna would be good for your test, if you can get enoughtop loading 
you

Would not need a base loading coil.

I ran 630M WSPR beacon last night , and was heard by manystations in EU.

Please, don’t tell me about the inefficiencies of short verticals on the low 
bands, or the propagation issues on 80m during daylight. These I understand. 
But I have a project in mind…..

My question is to ask if anyone on the list has ever tried this, and with what 
results? If any!

Thank you

Re: [Elecraft] K2 - (K2-100)

Gene,

I also thought Tom N0SS originated that mod, but I did not find it on 
his website (preserved by the Mid-Missouri Amateur Radio Club).

My computer has a  RS232 port and the female end of this cable will go

The male end shell will have to be notched since the socket at the rear 
of the K2 has a bump/tab which prevents someone from plugging in a wrong 
cable.  I am almost positive this mod was designed by N0SS but I can not 
seem to find where I saw it.

I don't think there is a lot of software that supports sending the FSK with

Funny, I just realized I was misreading “OT” as Occupational Therapy. Our son 
just finished OT grad school and is studying for the board. Of course, 
assistive tech is a big part of occupational therapy.

[Elecraft] KX3, QRP, /P, 80m, daylight

[J Chester]

I am planning to try this - the reason will become clear later. I want to use 
the KX3 in portable QRP operations on 80m, most probably during daylight hours.

Please, don’t tell me about the inefficiencies of short verticals on the low 
bands, or the propagation issues on 80m during daylight. These I understand. 
But I have a project in mind…..

My question is to ask if anyone on the list has ever tried this, and with what 
results? If any!

Thank you
