K3 PSK-D Split Operation
Locked
 
|
When in Data Mode PSK-D (31 bps) I get SPL N/A when trying to operate split.
Both VFO's were on the same frequency but could not get VFO B to go up. What do I need to do to go into split operation in this mode? Today VK0TH was operating on 28,121 MHz and listening 400 Hz up. I just could not get into split mode. 73, Bud W3LL [hidden email] ______________________________________________________________ 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 |

Hi Bud,
I suspect that VFO-B is in a different mode. (You can view VFO-B information mode by pressing BSET). To quickly solve this problem I just pressed the A-B (#3) button twice. The first push sends transfers VFO-A frequency to VFO-B and the second push transfers other information such as mode and maybe filter width. (See manual page 15). 73, Mike K2MK

Bud,
Most PSK31 waterfall software allows you to set the transmit frequency different from the receive frequency on the waterfall display. Yes, the K3 does not allow split in Data A submode - use your software application. 73, Don W3FPR On 1/5/2012 6:28 PM, Bud Governale, W3LL wrote: > When in Data Mode PSK-D (31 bps) I get SPL N/A when trying to operate split. > Both VFO's were on the same frequency but could not get VFO B to go up. > > What do I need to do to go into split operation in this mode? > > Today VK0TH was operating on 28,121 MHz and listening 400 Hz up. > I just could not get into split mode. > > 73, > > Bud W3LL > [hidden email] > > ______________________________________________________________ > 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 > 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 only way to split on PSK-31 is to use XIT. Just go up the necessary amount and transmit.
Works fine. 73 Bill, K4CIA ______________________________________________________________ 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 |

*Bill,
By all means educate me please. Why would split be used on a narrow bandwidth signal such as PSK31? Would you not be just consuming twice the amount of bandwidth as needed? I have casually operated PSK31 and I have not seen the band so crowded that operating split would be needed.

Split operation is dictated by the desires of the DX station. If he is quite rare, as in the case of VK0TH on Macquarie, he cannot hear the multitude of stations calling simplex and those calling simplex cannot hear his reply. So split is necessary to complete the contact. Exactly like cw, ssb or rtty.
My observations on this subject are based on using the native PSK capability in the K3, and not from some other software package. Split operation may be available from them as Don suggested.

Hi Gary,
Splits a bit of a misnomer when it comes to PSK or RTTY on HF bands while technically it's split operation in practice you won't need to change the Rigs frequency (normally). I use Ham Radio Deluxe and it is the same with a lot of the other programs. The rigs frequency remains the same and the audio tones are altered according to where in the 3khz band window you appear. It's very useful if your working DX because it allows the DX station to "choose" the best station to respond to. You can weed out those stations you already have or don't want to work and select the better signals or those not as obscured by others that might transmit over the top. Normally it's not an issue and split isn't technically necessary but when you have a thousand angry JA's all screaming for your attention its mandatory. Now if i could do the same with CW and SSB I might have some hope of retaining some sanity in the coming months. Hope to see your callsign in my log shortly. Trevor - VK0TH Macquarie Island |

And BTW, although the DX that Bud was asking about was listening up only 400 hz, the guys in the Solomon Is and the guy on Trinidade/Martim Vaz were listening up 2 - 5 khz. The simplest way to get the K3 to do that split is by using USB instead of Data mode.

The original question was about PSK D but the answers didn't address
that question. Assuming that Bud was really wanting to use PSK D with text decode on the K3 and direct CW to DATA then the K3 does indeed indicate SPL N/A. In that case XIT does offer a method by which to go split. If instead he was wishing to use a PC based PSK terminal then the correct mode would be DATA A. This does in fact allow split as does AFSK A and FSK D. This is all easily checked by switching DATA MD settings on the K3. If Bud has chosen PSK D in error wishing to use a PC based PSK terminal then the simple answer is to select data mode DATA A. This also has the advantage of flattening the EQ settings unlike USB which can have a very tailored EQ set-up to suit a voice/mic combo. When in PSK D mode, audio is still passed to the PC and signals are visible on the waterfall, this could possibly lead to confusion.

Quite often, when working DX, a simplex pileup can cause problems. Stations calling the DX can cover up reception of the DX station. The DX station works someone, but that someone can't hear because of all the other stations calling. This is true in CW and Phone, but is especially true in FSK and PSK modes, where only the strongest signals are decoded. By going to split, the DX stations keeps his frequency clear, so that all stations can hear him respond. This greatly speeds up the pileup, as those doing excessive calling won't interfere with a response from the DX. While such pileups aren't common in PSK, they are pretty common on FSK RTTY.
