GM Peter: Yes I've been doing that for over a year now with my K3. Rather
than use the internal decoder, I feed the Main audio from the DX station (VFO A) to one instance of MMTTY and feed the subRx audio (VFO B) to a 2nd instance of MMTTY and use two computer screens. This is particularly effective when also using the P3 to help spot where the last station worked was calling. 73, Doug VE3MV ----- Original Message ----- From: "VANO Peter" <[hidden email]> To: <[hidden email]> Sent: Wednesday, August 15, 2012 12:12 PM Subject: [Elecraft] Fwd: RTTY split operation > > > >> >> RTTY split operation >> >> >> >>> Hi all, >>> Is there a simple way how to monitor two channels in RTTY mode, like in >>> CW mode, to see the rare station working split and simultaneously find >>> in pileup the answering station?

Another way with one TNC or instance of MMTTY. Set L-MIX-R to Ab Ab.
That way you get both channels out on one audio channel. In practice that works just fine for a couple reasons. The DX isn't transmitting (though lids are) when tuning. It's pretty hard to decode but the strongest pileup signals anyhow. More reliable way of finding who is being worked is being able to decode 599 in your head. It is far more reliable than hoping for any program to decode a pileup. Works for me. 73 de Brian/K3KO On 8/15/2012 16:12, VANO Peter wrote: > > > >> >> RTTY split operation >> >> >> >>> Hi all, >>> Is there a simple way how to monitor two channels in RTTY mode, like in CW mode, to see the rare station working split and simultaneously find in pileup the answering station?

I usually use two instances of MMTTY, one with the left channel connected to
the main receiver in the K3 and the other connected to the right channel for the subreceiver. More specifically, the first instance is run in DXLab Suite's WinWarbler. By keeping the two audio streams separate you achieve the benefit of split frequency pile-up operation. The DX station is in its own decoding window, and the callers are in the other one. These days many stations continue to call even if the DX station has come back to one station and even while the DX station is still transmitting. The P3 is a big help, but stations who call continuously make it tough. It's also a problem, of course, if the callers are in your skip zone so you can hear them or see them on the P3. I think the K3's decoder is a neat feature, and I know many have used it successfully. In my opinion, it's not something I'd want to use in everyday operation. The same is true with sending RTTY with a CW paddle. For lots of help getting started with RTTY, http://aa5au.com/rtty.html is a standard reference. The RTTY reflector is also very helpful: http://lists.contesting.com/mailman/listinfo/rtty . I agree with Brian than recognizing 599 by ear is handy as is being able to tune a RTTY signal by ear. 73, Jim N7US -----Original Message----- Another way with one TNC or instance of MMTTY.

A panadapter is a helpful tool, but when you read comments to the effect that it makes DXing "like shooting fish in a barrel," you know the poster has not tried any real pileups. A panadapter doesn't tell you much when there are dozens of stations calling incessantly, both while the DX is listening and while he's transmitting. For RTTY, you can try two decoding windows as Jim recommends, or you can try to identify the station being worked by listening as others have mentioned. For CW, the panadapter may give you a clue where he is, but you can know for sure by listening. I have set up my split macro to provide a wide bandwidth on the sub-receiver, which can be quite helpful in pegging the DX's listening frequency. Skimmer is a good tool too, but for whatever reason I have never warmed up to it and I prefer the panadapter plus my right ear. Figure out where he's listening and how he's tuning, and you'll nail him with a lot less frustration and aggravation. 73, Tony KT0NY -- http://www.isb.edu/faculty/facultydir.aspx?ddlFaculty=352 ______________________________________________________________ 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 |
