SDC CW keying problem

[Juraj Neupauer]

HI all. I have 3 components connected to RigSync in SDC 17.1515:  

Elecraft K3 connected to real Com port 

EEsdr2 /colibri, used as panadapter/ connected as TCI client 

and N1MM connected  to Rig Emulator via COM connector. 

Everything is perfectly synchronized in all directions. Problem is the CW keying from N1MM: PTT command passes through to K3, but CW keying does not. Connections are OK,  settings DTR/RTS are correctly set everywhere. It is possible to key K3 by setting DTR line to High in Com Settings of K3 connection. 

Can anybody explain or help? Thanks in advance, Juro OM2XA

Juro, RIG Sync does not transmit DTR/RTS signals. To do this, you need to use COM-Spider. 

Two pairs of virtual COM ports are used: COM10-COM11 and COM12-COM13.

Dear Yuri, both synchronization and keying work as desired  with the setup you described. It also made clear to me what and how it is possible to do with SDC. Thanks a lot!  Juro OM2XA

Hello Yuri and Juro 

I thought this thread would be the most appropriate for the question I have. 

I have a setup very similar to Juro's and I made it all work thanks to details provided in this thread - thank you

- Elecraft K3s

- Colibri-DDC connected on the RX in/ RX out loop of K3 (not if).   

- EESDR3 1.0.6 beta which manages Colibri-DDC and will act as a pan adapter 

- SDC 17.2208x64 as CW skimmer with ComSpider, RigSync and SKM server working as previously described  

Everything works well together,  K3s and Colibri track each other.   I can control both radios with E-coder2 for fine tunning etc etc

One problem though is whenever I TX on K3s,  SDC Skimmer does not stop decoding.    When I TX on K3s,  SDC skimmer decodes my own call and populates entire band with my all call. 

The ask:    Can SDC inhibit SDC skimmer while K3 is keyed?    The keying is done via Comport.     

I also have SunSDR2DX and whenever I key the radio SDC skimmer will stop decoding but obviously this is completely different solution since all of it is done via TCI alone

N.B.  I have already unchecked "TX mode" option in RigSync but it does not make any difference when it comes to SDC Skimmer

Hi, Nick

I'm not sure if Colibri will stop issuing the IQ stream if it receives the "TX" command.

Therefore, the easiest way to solve this problem is to blacklist your call sign.

For example:
