Don - The Output of DK II is connected to the K3 ACC port using a DB15-EL-K3 cable supplied by microHam with the DK II.
73 Paulkc2nyu ----------------------------------Paul, Details on how you are connecting the DKII FSK output to the K3 please. A quick perusal of the DKII information indicates to me that the FSK output is from a computer COM port - which to me indicates that it is RS-232 levels. Those RS-232 levels must be converted to TTL levels by a "one transistor keying circuit" and the output of that circuit applied to the K3 ACC connector pin 1. The fact that you have a single tone indicates to me that you do not have anything connected to the K3 ACC connector that will pull pin 1 to ground. That means that the K3 will generate the space tone, but there is nothing to tell the K3 to change the tone to a mark tone. 73, Don W3FPR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Paul,
Make a test connector from a DB15 connector - so you can manually short between pin 1 and pin 5 - do not connect the Microham supplied cable. Start the 'send' process, listen for the single tone, then short between pin 1 and pin 5 - the tone should change. If it does, than the K3 is OK, look for the problem in the Microham box or the cable. If the tone does not change with that test, contact Elecraft support. 73, Don W3FPR On 2/7/2015 10:00 PM, paul ecker via Elecraft wrote: > Don - The Output of DK II is connected to the K3 ACC port using a DB15-EL-K3 cable supplied by microHam with the DK II. > 73 Paulkc2nyu > ----------------------------------Paul, > > Details on how you are connecting the DKII FSK output to the K3 please. > > A quick perusal of the DKII information indicates to me that the FSK > output is from a computer COM port - which to me indicates that it is > RS-232 levels. > Those RS-232 levels must be converted to TTL levels by a "one transistor > keying circuit" and the output of that circuit applied to the K3 ACC > connector pin 1. > > The fact that you have a single tone indicates to me that you do not > have anything connected to the K3 ACC connector that will pull pin 1 to > ground.

Paul,
I have used the microHAM digi keyer II with the K3 and MMTTY within Logger32 and using the K3 cable BD15-EL-K3. There are detailed configuration documents on the microHAM web site for a variety of applications. You do not need any level changers. It is all done in the DK II. When I bought a new PC the on board sound was perfectly good and I removed the DK. For me AFSK works fine with just a couple of audio leads and with PTT over the RS232 interface.

You are stating that you are trying to use FSK. MMTTY requires "EXTFSK" to be added to the MMTTY folder for it to be functional for FSK. Also EXTFSK needs to be configured. A small window will appear showing the lead assignments. These must agree with the com port assignments associated with the USB Router. EXTFSK is available on the MMTTY Web Site, just scroll down the MMTTY page and you will find where to download it. The page also has an excellent explanation on how to use EXTFSK. In addition make sure you have the K3's data mode set to FSK D. Should work, works for me.

Both interfaces provide a UART interface that works like a COM Port capable of handling 45.45 baud. Please see the example configurations for MMTTY with MK II and DK II in the MK II and DK II sections at www.microHAM-USA.com/support.html. 73, ...

EXTFSK is only required if a USB-Serial interface is used which doesn't have
an adequate UART implementation to support 45 baud and the 5-bit code. The Digi International Edgeport/4 and /8 interfaces work fine without EXTFSK. The microHam interfaces also work fine without the EXTFSK module.
