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

Re: K3 operating tip: RTTY operation without a computer

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???

Re: K3 operating tip: RTTY operation without a computer

Alan Bloom
In reply to this post by Van W1WCG
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.)

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