K3 operating tip: RTTY operation without a computer

If you're a CW operator but would like to dabble a bit in RTTY
(especially easy during a contest), you're in luck: You can use the K3's internal keyer to directly transmit RTTY. You can also copy RTTY on the K3's text display, making it a self-contained RTTY station -- no need to set up computer cables or software. Just follow the procedure below (all parameters are saved, so you'll only need to do the setup one time). 1. Tap either end of MODE to get to DATA, then hold DATA MD and select FSK D. 2. Hold PITCH and select a mark tone; I use 915 Hz. NOTE: No matter what pitch you select for FSK D mode, the K3's VFO will always show you your mark frequency. Thus there's no need to do any math to convert from an SSB suppressed-carrier frequency to the actual data carrier frequency. This makes RTTY operation very similar to CW: just tune in a signal and call them using the keyer paddle. 3. Hold TEXT DEC and turn the text decoder. You'll start seeing random noise characters on the VFO B display. 4. Tap CWT; the upper half of the S-meter will become an RTTY tuning aid. When tuning in signals, try to get the mark and space tones balanced in their number of bars on either side of the CWT pointer. 5. Set power to the desired level. The K3 can transmit at full power in RTTY mode. 6. Plug in a keyer paddle. Adjust the sidetone volume in CW mode (if necessary), then switch back to DATA mode. 7. Send a few characters with the paddle. If you don't hear the FSK signal, adjust the MONitor level (hold the CMP/PWR knob in to select MON level adjust). Note that you can adjust the levels in TX TEST mode, too, without putting out any power. This is a good way to practice with CW-to-RTTY. 8. If you pause, the K3 will remain in a data idle state for about 4 seconds before automatically returning to receive mode. To cut the 4 second timeout to about 1 second, you can send "..--" (IM prosign, for "IMmediately exit"). For further details, see the Owner's Manual, page 32 (revision C). Have fun! 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi Wayne,
Everything works great -- but how do I reverse mark and space tones? REV does not do this. I listened to a few test signals on 20m and then noticed that while sending in TEST TX mode, my mark and space are reversed from the prevailing on-the-air sense, with the mark being the high tone instead of the low tone. The LSB indicator is on while setting the data mode to FSK D, but it goes away after the menu is dismissed. But I can't seem to exchange or reverse the tones. Have I missed something??? 73, Van W1WCg K3 #42 ----- Original Message ----- From: "wayne burdick" <[hidden email]> To: "Elecraft Reflector" <[hidden email]> Sent: Friday, December 28, 2007 1:24 PM Subject: [Elecraft] K3 operating tip: RTTY operation without a computer > If you're a CW operator but would like to dabble a bit in RTTY (especially > easy during a contest), you're in luck: You can use the K3's internal > keyer to directly transmit RTTY.

For FSK There's a CONFIG menu item, FSK POL. 0 for inverted and 1 for
normal. 73 Greg AB7R -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Van W1WCG Sent: Friday, December 28, 2007 1:20 PM To: [hidden email] Subject: Re: [Elecraft] K3 operating tip: RTTY operation without a computer Hi Wayne, Everything works great -- but how do I reverse mark and space tones?

No I think it's working correctly. For standard RTTY, mark should be
high and space low. (If you're of a certain age, remember the mnemonic LSMFT - Low Space Makes Fine Teletype.)

And I thought that it meant "Lord Save Me From Truman" but that was a long
time ago.

You are dating yourself John! Unfortunately, that's the way I remember it
too! It also meant "loose suspenders mean falling trousers"!
