CW skimmer setup question
Locked
 
|
Just downloaded CW skimmer and am using it with the LP Pan, E MU 0202 and of coarse the K3. I am in the process of setting things up and has some questions. As well just wanted to share the setup options I chose just to make sure they are ok.
Under the settings tab....and then to the radio tab 1. I have set hardware to softRock-IF (as per LP Pan site) is this correct? 2. Sampling rate I am going to use is 96 and I did set the same on the E MU 0202 3. Pitch is set to 600 as is the K3 4. The Audio IF I am not sure what to set that too as I am not running any SDR software. The only answer I could find for the setting of the was to set the Audio IF at -6000 and take away the global offset from your SDR software. I am not using SDR software so is it left at -6000? The Audio tab is set as follows......... 1. Sound-card driver is set to MME 2. Signal and Audio devices are set to my E MU 0202 cards 3. Channels was left at Left/Right= I/Q 4. Shift Right channel data was left at 0 samples The Rig tab is set as follows.......... 1. Rig K3 2. Com port to be set when I use VSP manager to set up a virtual port pair. 3. Baud 38400 4. Data 8 bits 5. Parity none 6. Stop 2 7. RTS set to High....not sure about this? 8. DTR set to high as well and not sure about this? 9. Poll set to default 500 10. Time out set to default 4000. Not to concerned about other tabs at this moment in time. Just wanted to see if I am on the right track with those who have this program up and running with their K3 Thanks for your time Mike VE3WDM ______________________________________________________________ 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 |

The best place to get answers is the LP-PAN website. It has very complete instructions for both hardware and software.
http://www.telepostinc.com/LP-PAN.html For example, here's the page for the E-Mu 0202: http://www.telepostinc.com/emu0202.html If you still have questions after reading the website, the LP-PAN list is also available: http://groups.yahoo.com/neo/groups/LP-PAN/conversations/messages Search the archives before asking questions. If all else fails, Larry N8LP is very responsive if you email him directly: n8lp at telepostinc.com IMHO Larry's products and support are on a par with Elecraft's and I have no connection with him other than being a very satisfied customer for several of his products. 73, Bill W4ZV (LP-PAN #008) |

OK > The Audio tab is set as follows......... > 1. Sound-card driver is set to MME OK > 2. Signal and Audio devices are set to my E MU 0202 cards OK > 3. Channels was left at Left/Right= I/Q Depends on cabling and band . On 6m, I/Q must be swapped. Run a different copy for 6m with I/Q swapped. I set up my cables to match the cabling of PowerSDR. PowerSDR compensates the SWAP of IF frequency above 30Mhz automatically. So, for shortwave: SoftRock-IF, Audio IF= -6000, I/Q Left/Right Tune in a constant signal on your K3 . With the the above settings, the signal ( a continous dash on the screen) should be very close to the little green arrow. If it is a bit off, correct AUDIO IF up or down in small steps. If it is far off, you probably have the cables interchanged. Finally, if you tune your K3 e.g. lower in frequency, the dash on the screen should move up (= stay on its frequency) while the green arrow should move down (= indicate the new lower K3 frequency) and vice versa. If not, flip cables. Allow a moment for the screen to update. With this cabling, PowerSDR should run 'out of the box'. For 6m, use the same cabling/settings. Just flip I and Q or run a differnt copy with I/Q flipped. > 4. Shift Right channel data was left at 0 samples Probably OK -- Ohne CW ist es nur CB.. 73, Martin DM4iM ______________________________________________________________ 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 |

Mike,
Please see my embedded responses below: Just downloaded CW skimmer and am using it with the LP Pan, E MU 0202 and of coarse the K3. I am in the process of setting things up and has some questions. As well just wanted to share the setup options I chose just to make sure they are ok. Under the settings tab....and then to the radio tab 1. I have set hardware to softRock-IF (as per LP Pan site) is this correct? YES 2. Sampling rate I am going to use is 96 and I did set the same on the E MU 0202 OK 3. Pitch is set to 600 as is the K3 OK 4. The Audio IF I am not sure what to set that too as I am not running any SDR software. The only answer I could find for the setting of the was to set the Audio IF at -6000 and take away the global offset from your SDR software. I am not using SDR software so is it left at -6000? YOU WILL NEED TO ADJUST THE AUDIO IF SO THAT THE CW SIGNAL LINES UP WITH THE SKIMMER FREQUENCY INDICATOR, I.E. THE GREEN POINTER. MINE IS -5140. The Audio tab is set as follows......... 1. Sound-card driver is set to MME OK 2. Signal and Audio devices are set to my E MU 0202 cards OK 3. Channels was left at Left/Right= I/Q I HAD TO CHANGE TO Q/I. 4. Shift Right channel data was left at 0 samples OK The Rig tab is set as follows.......... I HAVE NOT USED VSP MANAGER...RATHER LP-BRIDGE, BUT SEE BELOW FOR MY SETTINGS IN THE SKIMMER CAT OMNI-RIG PANEL 1. Rig K3 2. Com port to be set when I use VSP manager to set up a virtual port pair. 3. Baud 38400 OK 4. Data 8 bits OK 5. Parity none OK 6. Stop 2 THE K3 USES 1 STOP BIT 7. RTS set to High....not sure about this? LOW 8. DTR set to high as well and not sure about this? LOW 9. Poll set to default 500 100 10. Time out set to default 4000. 100 Not to concerned about other tabs at this moment in time. Just wanted to see if I am on the right track with those who have this program up and running with their K3 Thanks for your time Mike VE3WDM

Two observations...
Poling rate of 100 is fine for LP-Bridge, since the traffic is intercepted and responded to from memory. With a standard bridging program, all those requests are passed on to the rig. In the case of the K3, eventually the data rate will exceed the allowable amount and cause issues. Timeout of 100 seems way too low. The program has to be able to try at least several times to respond to a request, especially since a standard bridging program allows packet collisions, and if there is just one compromised packet sent that the rig doesn't understand, there is not enough time for the next good one to get to the rig. 73, Larry N8LP On 9/2/2013 10:03 PM, [hidden email] wrote: > Date: Mon, 2 Sep 2013 18:11:20 -0700 (PDT) > From: Chuck - AE4CW<[hidden email]> > To:[hidden email] > Subject: Re: [Elecraft] CW skimmer setup question > Message-ID:<[hidden email]> > Content-Type: text/plain; charset=us-ascii > > Mike, > > Please see my embedded responses below: > > Just downloaded CW skimmer and am using it with the LP Pan, E MU 0202 and of > coarse the K3.
