K3SYN ?

wb9jph@...
 

Not sure if I want to upgrade my K3 with the K3SYN or sell it and move to the K3S.


I am a casual operator - PSK, RTTY, CW and SSB.


If I upgrade to the K3SYN are there any other mods that should be done?


Will a casual operator notice the gains from the K3S vs upgrading the K3?


Thanks for your input.

Re: [Elecraft_K3] Just Received K3S.

 

Or you can have the amp eavesdrop on the transmitted RS232 data, which is still sent to the RJ45 jack even if you have the computer connected to the KIO3B's USB port.

Bill,

If you order the antenna tuner at the same time as the K3(S), you will not receive the KANT3, and have to install the KAT3 when you build the kit.  The installation is very simple, just involves installing the ANT 2 connector and using the KAT3 board when you build the kit.

Obviously, if you buy the Ant tuner later, you have to take apart part of the K3 to install it; that is when you would need the assembly manual.

If you purchase the 100W amp with the kit, you install the shield when building the radio kit; this saves a bunch of time later.

With the sub receiver, if you are going to use the BNC connector, you install that when building the kit; additionally you will mount the DSP board in the front panel before mounting it to the chassis.  This is all spelled out in the radio assembly manual.  Again, if you purchase the sub receive later, there is a lot more work involved to mount the DSP board!!!

Re: Just Received K3S.

Rick Tavan
 

Does your amp accept 4-line "BCD" band data or does it insist on using a serial data stream? I've always used the band data from the K3 ACC socket, cascading true-15 pin Y-connectors as necessary to provide various signals to different devices. Works fine and doesn't depend on serial data stream timing.

If the amp insists on RS232 for band data, does it listen only (like a SteppIR controller) or does it insist on "talking" on the RS232 line? If it's listen-only, then you can cascade a 9-pin Y-connector.

If the amp insists on a bi-directional RS232 link, consider the various products that simulate multiple serial ports on a single computer input. I haven't used them and am just vaguely aware that they exist, but that might be a place to look if no other alternatives work.

Thanks Joe, found the peak hold.  Still on my P3 the blue modulation line is a slow arc but unless you are looking at the really low audio tones, -500 Hz, which are about -12 dB, the rest of the audio spectrum is -20 dB on my BC stations?  Still confused...  I took a picture and put it in my call sign photo.

Can't Get K3 to transmit DM780 PSK-31

Everett N4CY
 

Guys,

I was able to get the K3 to stop keying up, but I think I have a sound card issue, which I don’t know how to fix. I only have two selections when I am in the DM780 program options, sound card screen. The two options are, Digital Audio (S/PDIF) (High Definition Audio Device) and Speakers (High Definition Audio Device). I see nothing that says “USB Audio CODCD for output.

I am using Windows 7

K3 Won't Transmit with DM780 and Signal Link

Everett N4CY
 

Guys,

I need some help,  I can’t get my K3 to transmit using a Signal Link USB and HRD, with DM780. I am able to receive fine PSK-31 with out any problem. The TX ”LED” lights up when I send a CQ, but no power out. In reading on the Signal Link web site, it says that if the CAT control is keying the K3, then it is looking for the front panel microphone and not the line in jack. I did disconnect the PTT cable from the Signal Link to the rig and it still is keying the rig, so it does look like that may be the problem. So how do I disable the CAT key up mode?


What I described above may not be the problem, but for whatever reason I cannot get the  K3 to transmit in digital. Any guidance will be greatly appreciated.

Re: [Elecraft_K3] Just Received K3S.

I think you may find that the RS232 OUTPUT is active when on USB so the data going TO the USB port MAY still be going out the RS232 Tx data pin as well.  But the ACC connector is definitely active and band data is available on it regardless of USB or RS232 selection.

I will say one big disappointment is that it seems you can't have both the USB and RS232 ports active for CAT data. This was actually something I was really excited aboutl, because I could connect my computer via the USB port and use the RS232 port to send band data to my amp. I would love to be proved wrong on this count? 


Not sure if it is possible to re mediate this via firmware or if it is a hardware constraint. 


I'll try and set up virtual com ports to see if I can work around this

OK, as stated, I ran the peak hold which actually the average with a
setting of 20.
Peak Hold and Average are completely different settings. If you are
setting average to 20, you are not using peak hold.

You have to perform the test to see it your self.
I have run peak-hold while watching several of the local AM stations.
The "hold" line reliably settles to -6dB relative to carrier within
one or two dB over several minutes of time while a 20 period average
is often -15 or -20 dB compared to carrier.

Mine arrived five minutes ago.  Haven't even opened the box yet.  After taking it out of the UPS guy's hands, I had to wash mine and damp wipe the box. I think UPS uses their trucks to haul coal after dark.

Re: [Elecraft_K3] K3/P3 video display on AM vs SSB

But the difference is the display is the question. WHY?
Are you using the peak hold mode for voice modulation as Al ask
and I told you how to enable? There is a significant difference
between a static display of 1 KHz modulation and the dynamic
display of voice modulation. When you enable averaging, the
sideband level will appear lower based on the length of each
dynamic element as a percentage to the total averaging time.

*USE PEAK HOLD* and see if the peaks in the sidebands aren't
close to -6dB compared to the carrier.

Which is, of course, illegal as soon as he modulates the transmitter.
A 100% modulated 1 KW AM signal is 4KW PEP ... the legal limit (in the
US) for AM is now 375 W carrier => 1500 W PEP just like every other
mode.


With the Peak averaging set to max, the side band AM signals were
> 20-25 dB down from the carrier.


You are not measuring peak audio components - you are measuring the
average audio level. Instead of average, select MENU:PEAK to turn
on "spectrum peak hold" and set averaging to the minimum.

OK, Alan, Thanks for the input.

Here goes. I am monitoring a friend near by, 15 miles. I took care
to have him set up the 100 W SSB station and his 1KW AM station like
this.

In CW mode, send a 100 W measured carrier. I recorded the level on
the P3. Then had him transmit normal voice levels and the peak SSB
audio components reached the same level as the CW signal on the P3.

Then I had him set up his RCA AM transmitter to monitored 1 KW
carrier on the bird. I recorded the level on the P3, ~1-2 dB of 10
dB more than the CW signal. Same antenna on both.

I had him transmit a 1 KHz tone 100 % modulated and yes, the 1 KHz
was 6 db below the carrier at 1 KW on the P3.

Now I had him talk to the 100% modulation point on the AM
transmitter.

With the Peak averaging set to max, the side band AM signals were
20-25 dB down from the carrier.

If the premise is that a 100% modulated AM signal has 50% of the
power in the sidebands and 25% on each side, that is 500 watts total
audio and 250 watts on each side. So the level should be only 6 dB
down from the carrier.

The only difference is the complex audio components vs the signal
tone. So why is the SSB signal peaking at the 100 watt level and the
AM signal 10 to 15 dB lower?

Comments appreciated....

Which is, of course, illegal as soon as he modulates the transmitter.
A 100% modulated 1 KW AM signal is 4KW PEP ... the legal limit (in the
US) for AM is now 375 W carrier => 1500 W PEP just like every other
mode.

You are not measuring peak audio components - you are measuring the
average audio level. Instead of average, select MENU:PEAK to turn
on "spectrum peak hold" and set averaging to the minimum.
