On receive, I hear no signals. Antenna is connected.

 

On transmit, when I key the transmitter, the s-meter goes up two bars. When I hold the key down, I get one bar in the middle of the display. 

 

 

Thanks for any help

I agree and I haven't found a mode or condition where it doesn't work 100% as expected.

My Old K3 is in for repair and upgrade.  I'm replacing the K3io board
with the new "B" model.  Apparently from what i read i will no longer
need the line in and line out cables.  Am i reading that correctly?  It
will then use a regular USB cable from the radio as a replacement as i
understand it.  Is there a new firmware release that will address this
or is the latest that has been published going to work?  I'm wondering
what different settings will have to be changed.  I use it mainly on CW
& FT8 modes.

Re: K3 upgrade

You won't have to use the old line in and line out cables, but you can continue to do so if you wish. If you do choose to remove those two cables and use the USB audio codec in the KIO3B instead, then in your digital mode software you will have to change the sound card settings to use the K3's USB audio codec instead of whatever sound card you were using before, for both transmit and receive.

You will also want to use that same USB connection for an unrelated function, namely radio control from your software. You can do away with any serial cable, KUSB or whatever else you might have been using for radio control, and instead use the virtual serial port that is set up by the driver for the K3's new USB adapter. In the K3's CONFIG menu, change the CONFIG:RS232 setting to USB to enable the USB serial adapter. You will need to change the COM port number in your software to match whatever COM port number Windows assigns to the new port (which you can find with the help of the Windows Device Manager).

The K3S Owner's manual (page 18) contains more information on using the KIO3B's USB port.

Larry,

It depends.  I still use the line out to be send audio to the US Interface Navigator (FSK for keying RTTY).

U also use the USB for FT8.

Re: K3 upgrade

I just modified mine with the new synthesizer, KI03B, DVR, and TXCO and now looks and acts like my K3S's. Yep just use the USB for all of your digital modes. Makes thigs a lot simpler. If the factory is doing your mods it will be up to snuff and don't need to worry about that. Your settings for FT8 etc. shouldn't be too far off from what they are. I did all of mine myself and glad I did. I Use it primarily for Field Day but I wanted it to be the same as my other two K3S's.

Installing a KTCXO3-1

Mel Farrer, K6KBE
 

On getting ready to install the unit, it mentions the rectangular pad to be installed under the Xtal module.  No pictures to show that and the only thing in the package was a black thick rectangular block.  It is not what I would call a "pad".  What am I missing?  Thanks.

Can hear noise on K3, but no signals.  Antenna is connected,

When I key the transmitter, the s-meter kicks up two(2) bars and when the key is held down there is one bar in the middle of the display. Can't figure this out.

On receive, all I hear is noise, no signals. Antenna is connected. On  transmit when I key the transmitter, the s-meter goes up only two bars. If I bold the key down, I get one bar in the middle of the display. 

Any help is appreciated.

Re: Load VSWR spec for K3?

Bob McGraw - K4TAX
 

From Fred Cady's book "the K3S output will begin to cut back when SWR reaches about 2.5:1 when running 100 watts.  Higher SWRs can be tolerated at lower power."

Re: sequence of installation

Jason ONeill <gm7vsb@...>
 

Hi Todd,

 

I recently installed a whole bundle of additions at the same time, in two identical K3s, I found myself going backwards and forwards a lot with no guidance on which order to do it.

 

I’d recommend striping it down to install the KAT3A first as it’s the most mechanical of the 3 items to install. Then prior to re-assembly add the filter, then complete the mechanical rebuild leaving out the stiffener and 2nd RX until the end if you have it, then add the KXV3B.

 

  • Disassemble per KAT3A instructions
  • Add KAT3A
  • Add Filter
  • Partial assemble leaving out 2nd RX and Chassis Stiffener
  • Add KXV3B
  • Finish reassembly

 

Regards

Jason

Hi Todd,

Unless you are concerned about verifying correct function of each module individually, I’d install all three while the radio is belly up on the operating table. In any case, I can’t see any reason for a particular order of installation.

Hi Todd,

Once you have the top off, it's pretty easy to see what you have access to. Each instruction manual will tell you what if anything you have to move out of the way. I have done several installations and found them to be mostly straightforward with little guess work. Dig in and enjoy!

I don't have microkeyer...Sorry, however I have run WSJT-X and FlDigi for years with just two cheap stereo jumper cables that are sold atmany places for cheap.  Computer MIC to LIne OUT. and Headphone OUTPUT at the computer to Line IN.  The K3 is buffered and that is all you need to run any and all digital modes...Hope that info helps for now so you can run WSJT-X until you can figure out how to get the more complicated MicroKeyer working
Same basic setup here with the K3. Can't beat the simplicity and the cost of the interface - two shielded audio cables.
