K3 - KDVR

Hi Fred. The answers to your questions are mostly "yes". Read the following from Iain in response to my query on the NCCC reflector. I'm sure Iain would answer more specifics if you need them.

Hi Barry,

Yes, I was using the KDVR3 for "voice keying" - really I only used it
for my CQ(s). N1MM doesn't explicitly support use of the KDVR3, but it
does allow you to send arbitrary commands to the K3, so I use the
commands that emulate pressing the M1-M4 buttons. I was pleasantly
surprised yesterday when I instinctively hit the Escape key to
interrupt my CQ when I thought I heard someone calling, and it
actually worked! I'm really not sure why it works - there may be some
hidden magic that sends a stop command to the K3 on hitting Escape. I
have yet to inquire about that.

Anyway, here are the messages I use for this... theoretically this
should work for SO2R, but I haven't really tested that thoroughly (I
only have one K3 at home)...

F1 CQ,{CATA1ASC K31;SWT21;}{CATA2ASC K31;SWT21;}
F2 Exch,{CATA1ASC K31;SWT31;}{CATA2ASC K31;SWT31;}
F3 Thanks!,{CATA1ASC K31;SWT35;}{CATA2ASC K31;SWT35;}
F4 {MYCALL},{CATA1ASC K31;SWT39;}{CATA2ASC K31;SWT39;}

The main benefit of this is that it avoids all of the hassles of
getting the audio routed through the computer working right and
sounding decent - instead you just plug your headset (or fav mic)
straight into the radio and go. Message recording is done with the
buttons on the radio. Listeners should be unable to distinguish
recorded vs live audio, other than by the repetition.

A possible down-side is that N1MM doesn't know when the playback of a
message ends - in fact it doesn't even know that a message is being
played. Things like repeating (or, worse, dueling) CQs could be a bit
tricky.

For something quick and easy, it works quite well...

Re: K3 - KDVR

Brett,
As I see it the advantage is that you can send messages from the keyboard
(particularly useful if you have an SO2R setup with the radios spread
apart). Furthermore, you can integrate the message sending into the normal
message sending functionality, like message repeating and hitting ESC to
stop it. I do that with my logging program, CQPWIN, and find it's more
convenient than continually using the radio buttons. I do have to have the
program calibrate the length of each message first, to be able to do the
repeating properly. It works fine.

Re: K3 - KDVR

In reply to this post by Brett Howard

For contesting, it is WAY more effective to be able to control the DVR
from N1MM than from the front panel of the K3. It's tiring and wastes a
lot of time to move your hand back and forth between the keyboard and
the rig multiple times for every contact. For example:

1. move hands to K3 to press M1 for CQ or M3 for "thanks/73"
2. move hands to keyboard to type callsign of next caller
3. move hands to K3 to press M2 for report; wait for acknowledgment and
report
4. move hands to keyboard to type report
5. repeat

Requests for repeats add additional motions.

When I bought my K3, I specifically did NOT buy the DVR because I didn't
think it could be controlled from the logger. Now that I know
differently I'm seriously considering buying one for the same reasons
described by N6ML below.

By the way, I since found out that the "RX;" command is sent to the K3
on hitting "Esc[ape]" iff the COM port configuration has "Radio PTT
via command" checked. This has the nice effect of canceling DVR
playback on hitting Escape.

It's just a matter of what you are used to, Brett. Most contesters I know like to do as much from the keyboard as possible and would rather not reach over and hit buttons on the radio.

Thanks Iain. Works like a dream when I figured out that I simply need
to cut-n-paste the {CATA1ASC K31;SWT21;}{CATA2ASC K31;SWT21;} and
similar commands from your earlier message into N1MM's config SSB
messages option for the relevant message, in place of the wav\
stuff in there by default.

I guess we can trigger messages M5-M8 as well with the appropriate
commands? I'm thinking that, for a multi-single club effort in CQ WW
SSB, we might get the two main ops to record their messages in banks
1-4 and 5-8 respectively. Mind you, it's easy to re-record any
message on the K3, much easier than messing around with WAV files on
the PC.

Anyway, I think this feature might *finally* be enough for the K3 to
displace the FT1000's from the club!

Re: K3 - KDVR

In reply to this post by Barry Pfeil

Gents:

Im trying to understand the need to even *consider* a KDVR
module.

I use N1MMLogger, and have for over 4 years now. I can
record, not only messages, but numbers and letters and
phrases into the computer (pre-air processor, using my air
mic) and off air audio, up to the limiting amount of storage
that my computer's hard drive has (zillions and zillions of
messages, hours and hours of QSO's!).

The Logger software can parse the letters and numbers. It
sends, not only pre-canned signal reports, but dynamic
callsigns and serial numbers live. If I choose to, I dont
even have to talk at all in a SSB contest (ever work Jamie,
NS3T? You worked a DVK!).

Not only this, but with the "Enter Sends Message" feature of
Logger, I input the callsign and hit the enter key, and the
software sequences the correct function key for the QSO step
automatically. It even logs the Q when done and sends QRZ
for the next one.

In multioperator situations, I can have all the operators
using the station record the messages and when they take
their shift, they press CTRL-O, put in their callsigns, and
the software will load the Logger's DVK with their own
personal voice message files automatically.

Although I use a MicroKeyer 2, K3 makes interfacing to the
computer as simple as plugging in the soundcard line out
into line in on the back of the radio and plugging the
soundcard in (not really needed, but useful if I set Logger
to record each QSO) into the line out of the K3. So, worst
case, you need a USB to serial adaptor for CAT and two 1/8
inch stereo cables for audio I/O.

If I ever want to go portable or operate at another station
with my K3, I take my MicorKeyer 2 and the K3 interface
cable with me. Then, one single USB cable is all that is
needed to interface the computer to the MicroKeyer 2 for
full DVK, CAT and all other feature functionality in SSB,
CW, RTTY and PSK, along with any other soundcard based mode
I desire to use (The MicroKeyer 2 has its own built in sound
card).

By the way, N1MM Logger is Freeware.

I own lots of options for my K3, but KDVR is not one of
them. Is there any compelling reason to even *own* this
accessory, other than having a computer-less environment
which, in today's contesting environment, is not going to be
very competitive (unless your QTH is P5, Mt. Athos or
something exotic)?

Re: K3 - KDVR

I've done all that as well (or at least most of it), but it takes a
moderate amount of time for me to check and edit the recorded audio
files to make sure they sound as close to my normally transmitted voice
as possible (same volume, etc). I've heard some truly horrible examples
during contests where the voice file and the real-time voice sounded so
different that you'd swear it was a different person. I even had one
contact with a station where the recorded voice was from a man and the
operator was a YL! Any confusion that sort of thing causes just slows
the QSO rate.

I don't own a KDVR (yet), but one of its potential advantages would seem
to be the ability to quickly set up voice memories for a new contest
that sounded exactly like your normal mic voice without any additional
editing.

Re: K3 - KDVR

As an example of use of the K3 DVR, in March I was operating ARRL Phone
froom P49Y. When operating split on 40m you have to change your listening
frequency every so often. Although I generally use prerecorded messages for
CQs, in that case it was easy to just record a new message in M1 on the K3
announcing the updated listening frequency, then send it from the keyboard.
Having the K3 DVR was very useful in that context. Also, if you are ever
having computer audio issues, perhaps due to rf pickup, sending the messages
directly from the radio does bypass all those problems. So I think it's a
good fall-back option.

Re: K3 - KDVR

In reply to this post by Barry Pfeil

Well, as a Fall back redundancy option, granted, its a
consideration.

However, it is no problem to record on the fly using N1MM
when you either run the mic line through the sound card (as
I used to do) or split from a mixer (as I do now with a
cheap Behringer EuroRack mixing board). You just hit TEST
on the K3, hit CTRL-Shift-F1 on the computer and record the
new frequency into your message. For example, "W4LT
listening this frequency and 7.090". to check it, just hit
F1 and it will play back. Re-enable TX by hitting TEST
again. This way you actually hear it through the radio
monitor.

Regarding the levels and editing, none is needed. The level
should not be any different than the level you are
transmitting with, because, well, youre transmitting through
the soundcard as well as recording! Editing is simple, you
dont like what it sounds like, re-record it by hitting
CTRL-Shift-F1 till you are happy with the result.

Computer audio RF issues should have reared their ugly heads
when you were doing setup before the contest, not during
one. The beauty of K3 is that you really dont need an
interface at all... The transformers are built in. With K3
and MicroKeyer, you double buffer the i/o lines with
transformers on both sides... I have NEVER experienced RF
issues with either MK or MK2 (I own one of both), in fact,
using a admittedly "dirty" OCF dipole, the MK's actually
REMOVED the little bit of RF I was getting into the audio
with my old Kenwood TS850 and that antenna.

Frankly, computers do break, but so do radios. The only way
to have full redundancy is to bring at least two of each
part... That gets expensive.

So how much are those five nines worth to you?

In reply to this post by Lu Romero - W4LT

That's simply not true. There are all sorts of settings that can make
audio sound differently going through the sound card one way versus
another. I check my on-the-air signals and they are typically different
without some adjusting. Other contesters do the same editing that I do
to get their recordings to sound the same as their mic voice. Ask
around ... you'll see. I suspect you've never checked your transmitted
signal with a different receiver to make sure. I do.

Maybe your recordings always sound the same as your mic voice, but there
is nothing that says that will be the case in general.

Re: K3 - KDVR

I tried
{CATA1ASC K31;SWT21;}--CATA2ASC K31;SWT21;}
and it did not work. It worked when I removed "--" and accidental spaces around SWT21.

Half of the command
{CATA1ASC K31;SWT21;}
plays just as well. What is the meaning of the second half?

Don't know where the '-' came from - it should be a '{'.

It was an attempt at an SO2R configuration, which I never really fully
tested. "CATA1ASC" means "send this to radio 1, iff it is currently
active". There is no "send this to the currently active radio" symbol,
so I had to send to both, but only if they're active, which seemed to
achieve the desired effect.

I will probably use the KDVR3 with N1MM for Sweepstakes this year, as
I'll be a guest operator at another station (with real antennas), and
will be taking my own laptop. The built-in audio on the laptop is
garbage (when the gain is cranked up high enough for a Heil HC4 as
input, it has all sorts of nasty noises in it), and none of the USB
audio devices that I have seem to do duplex audio in the way I need
for N1MM software voice keying....

I do use N1MM software voice keying for other contests, including SO2R
SSB. It works well most of the time, with a decent sound card. For a
simple single-operator contester who just wants to have a convenient
recorded CQ and maybe exchange, the KDVR3 method can be easier than
messing around with Windows audio, and there's less to go wrong...

Re: K3 - KDVR

Ian:

I dont think you are understanding what I am saying...

You DO NOT use "Windows Audio" OR the laptop's soundcard at all. The
"Soundcard" is built in to the MicroKeyer 2. It is specially designed for
this application, with low noise and high dynamic range plus a standard
codec driver. So you just connect the rig to the MicroKeyer 2 and the MK2
to the laptop using USB and everything works, even my HC4 Boomset through
the MK's External Mic in.

And there is no need for special CAT commands in the macros or the use of
PTT by radio command that can get messy since Logger just sends the CAT
command like a UDP packet.

But, to each their own, if it works for you, I'm glad.

I look forward to working you on SS. I will be using my K3 driven with my
MK2 from home.

In reply to this post by Barry Pfeil

Dave:

If you are messing with Windows Audio, through a computer's "general use"
sound card, I can agree with you. Windows often changes settings as you
open and close multiple programs.

However, since I plug the mic into the MicroKeyer directly and its internal
sound card is passing both my live audio and my recorded audio, that is
recorded through that same sound card with the identical settings, PRE AIR
PROCESSING, there is absolutely no difference as long as my voice stays
fresh (which it doesn't, but that's a wetware issue, not a hardware or
software issue).

Granted, you do have to do a bit of "setup" before hand to make sure the
levels are correct (what you call "different without adjusting". I
adjust!). I do this ahead of time and lock the settings. And once I do
this, I don't mess with them again. I am then guaranteed the same
consistent levels upon subsequent recordings "on the fly" through Logger's
facilities.

I do trim my recordings for canned messages at times as well, especially
numbers and letters, using NCH WavePad. However, I record the raw mic
signal through the MK2 into the computer and NEVER apply any processing at
all at this point. The rig's processor and EQ will then handle both my live
audio and my canned audio with the same processing, making them as near
identical as the sampling rate will allow (I am a "audio dweeb". I hear the
quantizing, but I can rationalize the bit rate!) This even worked with my
original MK, using a Delta 44 sound card in the computer (NOT the crappy one
on the motherboard or a $19 Geeks.com special).

I most certainly do listen to on air signals with my secondary TS-570
transceiver during setup over RF, although now, with the K3 rather than my
previous TS-850, the local monitor with TX off is pretty darn accurate, in
my humble opinion.

I made my living for over 30 years making sure quality sound and picture was
transmitted over RF and I always made my MCR operators and production audio
ops mix to the off air signal after processing for best accuracy. So I
understand the issues.

My recordings sound really really close to my live voice (at the start of
the test when its fresh, not after 46 hours of saying "Five Nine Zero Five"
a thousand times, though!) because I put the work in ahead of time to make
sure that they do and leave the settings alone. Other ops mileage,
especially the incessant tweakers, may vary.

That's simply not true. There are all sorts of settings that can make
audio sound differently going through the sound card one way versus
another. I check my on-the-air signals and they are typically different
without some adjusting. Other contesters do the same editing that I do
to get their recordings to sound the same as their mic voice. Ask
around ... you'll see. I suspect you've never checked your transmitted
signal with a different receiver to make sure. I do.

Maybe your recordings always sound the same as your mic voice, but there
is nothing that says that will be the case in general.
