Lee,Tony has explained the concept of split nicely. It takes a bit of practice to get used to it and it can be frustrating until you learn how the DX is moving around in his listening window so you can have a chance to be in the right spot at the right moment. The thing to remember is you may see "UP 1-3" on RTTY due to the narrow band width of a RTTY signal. On CW the split range may also be fairly small, but on SSB the typical split listening frequency is "UP 5 - 10". On some very rare DXpeditions they may go overboard and announce "UP 10 - 20". I personally don't like a wide split like that because all it does is spread QRM all over the band. If you haven't operated split before be sure to check your radio owners manual for how to do it quickly and easily. Practice on learning how to get Split activated and the second VFO on the correct frequency. Also practice setting up split for "DWN 1-3" as some DX will do this on the lower bands. You may also find the DX is listening in a frequency range that is outside the US band limits for that band. This effectively cuts out all the US stations from the pile up and significantly reduces his QRM. At other times you may hear the DX say "EU" (Europe), or "NA" (North America). or "AS" (Asia) in an attempt to limit the number of calls coming from the pile up. Wait until he calls for "NA" or drops the area designation altogether before calling him. If your radio has a second receiver or, in the case of some Icom rigs, Dual Watch, listen to the pile up a bit to get a feel for what is going on and how the exchanges are being sent. Make sure your TX frequency is in the range the DX is listening to and that your RX is on his TX frequency. When you tune, make sure you are tuning YOUR TX frequency, not the RX frequency. Finally, when you see that rare DX operating "Split" be sure you are set for split before calling else you will awaken the frequency cops who will pounce with a vengeance to remind you to TX "UP UP UP UP!" 73, Gary AL9A----- Original Message ----- From: "N2TK, Tony" <tony.kaz@verizon.net> To: "'Lee Roberts'" <ham@n0sq.us>; <rtty@contesting.com> Sent: March 26, 2013 2:53 PM Subject: Re: [RTTY] DE T2YY UP 1-3? Hi Lee, The big advantage is that the DX can run more stations in an hour of operating time than if he/she were transceive. When you have a wanted station on the air it makes it easier for the DX station to pick out a signal when they are spread out. In addition, it makes it easier for the calling stations to know when the DX has come back to someone. If you havesome loud stations calling the DX right on his/her frequency it may be verydifficult to hear when the DX came back to someone.When on CW the rates can increase when you are using QSK. You then know whenthe DX has come back to someone while you are sending your call. As an example, if someday P5 legitimately comes on the air you will mostlikely see quite a big split. I would probably take off of work just to worka P5 on CW and RTTY. Only have it on two bands on SSB. 73, N2TK, Tony -----Original Message----- From: RTTY [mailto:rtty-bounces@contesting.com] On Behalf Of Lee Roberts Sent: Tuesday, March 26, 2013 6:20 PM To: rtty@contesting.com Subject: Re: [RTTY] DE T2YY UP 1-3? Why would they do that? Is there some kind of benefit to operate split?

In other words within that range. 73 & GL, Douw W4OX -----Original Message----- From: RTTY [mailto:rtty-bounces@contesting.com] On Behalf Of Lee Roberts Sent: Tuesday, March 26, 2013 12:20 AM To: rtty@contesting.com Subject: [RTTY] DE T2YY UP 1-3?
