K3: The ARRL RTTY Round UP

k0wa@swbell.net

Ladies and Gents....

I just about cleared a thousand Qs this weekend in the RU in only 17 hours of on-the-air time.  The K3 was spectacular in performance.  The RX is magnificent and copied signals that I could not hear out of the speaker but printed on the screen.  This happened many times.  From Kansas, I did get to work some deep Europeans and even Israel called me.  I did not hear any Russian stations at all.  The DX was weak but workable.  Magnificent RX.  The TX was healthing and robust.  I was running my amp so I was only running about 60 watts or less.  The TX stayed cool and stable.

The only issue I noticed was that between Dual PB on and off...the power would drop about 200 watts.  No big deal, but interesting phenomonon.  With the Dual PB on...the power would drop...with it off...the power would return to normal.  Wayne and Eric already know about this issue.

Thanks to all who worked me.  Fun contest.

Re: K3: The ARRL RTTY Round UP

Darwin, Keith
So THAT's why there was RTTY all over the CW portion of 40 meters.  Contests - gotta love 'em LOL

Yep, contests are much more important than gentlemen's agreements and courtesy
these days. (IMHO)

Lee and All,
 
I tinkered with the contest for a couple of hours too.  I used a pretty spartan setup though--just the K3 with a couple of programmed memories--no computer.  I set the power to about 60 watts, and was knocking them off pretty well too.  I know I need to get set up a little more substantially for RTTY, but I was just playing around.  Anyway, it was a hoot, and the K3 did great.  The versatility of the K3 sure makes it a lot of fun to own.

Unfortunately, the amount of CW activity that I heard didn't come close to
filling up the amount of available space below where the RTTY folks were
operating.

In reply to this post by k0wa@swbell.net
My pair of K3's also worked well in the RTTY Roundup - 1800
qso's. There are only a couple of issues that I saw:

1. On each transition between mark/space, there is a brief
upward power excursion. One of my amplifiers has an LED
wattmeter, and one of the LED's was blinking like crazy.
Also, the screen current on that amp was varying
significantly. I've complained about this in the past.
Elecraft is supposed to be working on it.

2. When you reduce the DSP bandwidth to 300 Hz, it is not
possible for me to get the audio output exactly centered
between the RTTY modem's mark and space detector. The SHIFT
control is too coarse. One click of the SHIFT control moves
the audio either slightly left of center, or slightly right
of center. It would be nice if there were a "fine mode"
setting for the SHIFT control.

I can live with both of these issues, but fixing them would
make this rig absolutely perfect for RTTY, at least for me.

Oh, please spare us the holier than thou attitudes.  The
"gentlemen's agreements" and "bandplans" on 40 meters have
recognized RTTY use of 7030-7060 (+/- on both ends) for
contests and international QSOs for at least 30 years.

There is more than enough CW spectrum both above (as high
as 7125) and below the area used on only a few weekends
a year by RTTY contests.

K3: The ARRL RTTY Round UP

timjp
In reply to this post by w7aqk
I only have had a handful of RTTY contacts since getting my K3/10 (# 0430).  Did play in the RTTY Round Up for a few hours.  Cranked it down to 1 watt (I don't know why I keep doing that!) and worked 74 Qs and 31 Mults.  Even worked Lee in KS (who bagged over 1K Qs! ) Like Dave, I programmed two CW memories (no [external] computer) and let her rip for search and pounce.  Even worked  LU, JA, XE, P4 plus several states.  That was fun!  Antenna, by the way, was my lame 88' dipole with one leg kind of vertical and fed with 450 ohm ladder-line. 

Did notice, espcially on 40m yesterday afternoon, that there were solid RTTY sigs from 7.000 - 7.100 MHz.  Guess it's the WARC bands if you're looking for a CW ragchew.  I do hear some of the digital guys complaining about CW contests on different weekends though so I guess we get to trade a bit.

Changing SHIFT and WIDTH granularity to 10 Hz from 50 would improve CW useability as well.  

A lot of us have formed contest operating habits and tactics based on analog SHIFT and WIDTH functions. Like a combination of a small shift and (sometimes) a lesser width change to put someone up or down just a bit farther down the passband and keep the same skirt frequency on the opposite side of the passband.

I agree that finer steps to SHIFT would be nice, but until then,  
wouldn't it be possible to center the audio using RIT?

Re: K3: The ARRL RTTY Round UP

In reply to this post by Guy, K2AV
"Roger that" regarding shift and width granularity!

I had great success (for me) in RU using my 200 Hz 5 pole filter with the DSP width set at 200 Hz and moving the filter offset frequency (FLx FRQ) about 30 Hz from normal to center up the passband while looking at band noise with MMTTY. I used 1275 Hz Mark frequency. DSP LO was 1.3 KHz and HI was 1.5 KHz. Moving the filter offset allowed both mark and space signals to come through at similar amplitudes. If the DSP resolution below a few hundred Hz would switch to 10 Hz resolution, it would be a real help and should probably alleviate jockeying the filter offset. In my case sensitivity might improve a bit, too since my mark frequency was 25 Hz outside of the stated DSP passband! With 10 Hz resolution,  the DSP could be set something like 1260 through 1460 Hz. (or whatever produces the best looking response in the desired audio passband) without tweeking FLx FRQ.  At any rate, even with 50 Hz granularity this setup allowed me substantially better copy of weak TTY signals in a crowded band than did the DUAL PB in the more conventional manner (while using MMTTY). The radio performed flawlessly for me in my first RTTY Roundup (Single Op, Low power, 530 Q's, 56 Sec,  35 countries, all S&P). The radio was run in the FSK D mode with data decoding always running.

Incidentally, my fancy new LCD computer monitor uses a capacitance touch power switch which would frequently turn off the monitor when I was transmitting on certain bands (40 or 20). But I never lost a Q because of this because I could always copy the RTTY on my K3 decoder display and would occasionally grab the paddles to send if the stations call had not yet been entered in the logging program (N1MM). It always took a few seconds for the monitor to reinitialize once I was able to turn it back on though it seemed much longer than that in the contest. My next ham radio task may be modifying this monitor.

wattmeter, and one of the LED's was blinking like crazy.
Also, the screen current on that amp was varying
significantly. I've complained about this in the past.
Elecraft is supposed to be working on it.

2. When you reduce the DSP bandwidth to 300 Hz, it is not
possible for me to get the audio output exactly centered
between the RTTY modem's mark and space detector. The SHIFT
control is too coarse. One click of the SHIFT control moves
the audio either slightly left of center, or slightly right
of center. It would be nice if there were a "fine mode"
setting for the SHIFT control.

I can live with both of these issues, but fixing them would
make this rig absolutely perfect for RTTY, at least for me.

Ladies and Gents....

I just about cleared a thousand Qs this weekend in the RU in
only 17 hours of on-the-air time. The K3 was spectacular in
performance. The RX is magnificent and copied signals that I
could not hear out of the speaker but printed on the screen.
This happened many times. From Kansas, I did get to work
some deep Europeans and even Israel called me. I did not
hear any Russian stations at all. The DX was weak but
workable. Magnificent RX. The TX was healthing and robust. I
was running my amp so I was only running about 60 watts or
less. The TX stayed cool and stable.

The only issue I noticed was that between Dual PB on and
off...the power would drop about 200 watts. No big deal, but
interesting phenomonon. With the Dual PB on...the power
would drop...with it off...the power would return to normal.
Wayne and Eric already know about this issue.

Thanks to all who worked me. Fun contest.

So far as the audio passband one hears, the RIT is no different than the
main tuning knob.  If one is mainly hearing 2150 to 2450 with a 300 hz
filter, and you are trying to receive 2125 and 2295 changing the RIT to get
those tones will still put the 2100 on the filter skirts.  Only the shift
will move the heard audio passband down to center around the standard tones.

On a run frequency, one usually locks the TX frequency, and adjusts
shift/width of passband for the "regular" listening width and centering,
saving RIT for listening only for temporary excursions to someone who calls
really high or low.  Contest programs can reset RIT when a QSO is logged.
They will not change shift. RIT is expected to be temporary per QSO. Shift
is considered a manual adjustment that the program leaves alone.

73, Guy.

Contesters and Band Conjestion

The reality of worldwide frequency allocations is that on some
bands, contesters MUST violate bandplans to work stations outside
their own country. On 40M, for example, JA stations have a rather
limited bandwidth to operate RTTY and it's pretty low on the band.
On 80M, RTTY cannot operate above 3600 kHz due to a rather dumb
error made by a low level FCC clerk who rewrote the ham Rules
several years ago. One of our club members, operating from Aruba
(in the Caribbean) made 409 contacts on 80M, 809 on 40M, 1,127 on
20M, and 869 on 15M. This is in 24 hours of a 30 hour contest
period. That means there were at least that many active stations
that had to cram into the spectrum that the FCC gives us. There
are similar conflicts with SSB operation worldwide, especially on
40M. Our club alone had 77 members on the air in the contest.

There are MANY times when I can tune across 80M during hours of
darkness and hear NO signals at all. There are MANY times I can
tune across 40M and hear fewer than a dozen CW signals and half
that many PSK signals. On a non-contest weekend, perhaps twice
that number. Assuming two people per QSO, that means casual QSOs
are sharing a band with a FAR larger number of contesters. In
other words, casual operators are simply a few percent of the
total number of hams using the band. Heck -- a good contester can
easily run 50 QSOs per hour using a few hundred Hz bandwidth (if
he's got a K3) and the top contesters run at twice that rate.

The good contesters I know all listen before transmitting, and ask
if the frequency is busy if they hear nothing. But band conditions
change, sometimes rather quickly. A station can be running on a
frequency for an hour, and conditions change so that you and he
are now hearing each other. No one is being discourteous, it's
just band conditions. Last week during Stew Perry, I'd been
running a frequency for a half hour, and was making Qs as far as
the east coast (I'm near SF). A W2 shows up, doesn't hear me (he
probably had a big noise level, or maybe was on a Beverage pointed
to EU), so no matter how many times I told him QRL, he ignored me.
Discourteous? Probably just his local noise.

Note also that contests never use the WARC bands. 30M is a great
band for CW ragchewing, and I've never heard it crowded (except
when a couple of really rare DXpeditions are there at the same
time)!

Unfortunately, you are correct. Thankfully there are still some CW only segments to keep all the SSB contest stations at least a little way away.

We CW "casual QSO" people do have trouble with RTTY people all over the
place.  Many times 30 meters no good for short path QSO's.  We need to put
pressure on FCC or whoever to allow CW on at leat a couple of the 60 meter
"channels" setup for SSB only.  Would be easy about 200 Hz lower than
"supressed carrier" frequency and still be in the alloted "channel", and for
the most part, not QRM SSB on same channel.

But then, too many "commissioners" and lower level people are NOT ENGINEERS!
This would allow "casual CW" QSO's on a band that propagation would probably
be possible for short path stuff when 30 meters is "tanked" for that.

Thanks to the reduction of 80 from 3500-3600 instead of 3500-3700 the RTTY
guys are in a quandry, NTS die hards in a quandry and CW people in a
quandry!  The "other" bands were more sensibly reduced....why didn't they
follow the same pattern for 80 meters and the NTS+CW+NTS guys would still be
where they were before basically!

80 meters has been terrible since the "change".  For everyone except the
"voice" guys who seldom use the 3.6-3.7 segment!

I use the 200 hz filter on RTTY all the time including
the ARRL RTTY Round UP.
I set up my 200 hz filter as a 300 hz filter in the
config menu.
I used DATA A and 1500 hz with the PWR setting
cut back to about 40 watts which gave me about
80 watts on the meter but it seemed to work well
for me until the power issue is fixed.
I used MIXW and set up F12 to
<ALIGN:1505>
<CATCMD:k31;fw0030;k30;>
<SPZOOM:4>
Then I set up F8 to
<CLEARTXWINDOW><CLEARRXWINDOW><CLEARQSO>
<CATCMD:k31;fw4000;k30;>
<SPZOOM:2>
and F4 to
SAVEQSO><CLEARTXWINDOW>
<CATCMD:k31;fw4000;k30;>
<SPZOOM:2>
I have the 6 khz filter and could click on any
signal in the wide spectrum than hit F12 and
work them. The program even marks the
stations I have already worked in RED on
the water fall.
I set up F1 to call and f2 to exchange.
I am not much of a contester and only put
in a few hours for a total of 58 contacts but
the people I worked did not know that.If
I had put in more time I know I could have done
much better.
73 and hope this works well for other people.
