CQWW RTTY - K3 Experience
Locked
 
|
I worked the CQWW RTTY contest last weekend. After nearly 30
years of amateur radio operating, I have never had more than a handful of RTTY QSOs
so I struggled from the start with accepted contest procedures and also the rig
set-up necessary to maximise copy of the wanted signals and the rejection of
adjacent signals. I cracked the procedures quite quickly but the copy problems
continued for some hours until I cracked the filter set-up. Once I set the high
and low cuts to just past the mark/space tones it was so simple and I posted
260k+ points easily. I have the filter shape settings for this type of
contesting saved now. Another problem for me was the line input from my pc for
the tones was set at ‘3’, anything more and the whole thing over
modulated and caused my linear to pop, especially on 80m. Having said how flawlessly the K3 performed, it was
complemented by N1MM’s cracking software which does just about everything
for you. Whether I was running or S&P the only effort required was turning
the VFO and clicking the mouse – easy contesting! (Oh dear! Another
marketing slogan from me – sorry). I’m looking forward to seeing
how this set-up works in the SSB and cw legs over the next couple of months.

So you were one of the RTTY signals filling up the CW bands!

I had a few spare moments this weekend and took the CW-paddle for about 100 RTTY QSO's during the CQWW. Boy, that was very easy and, most of all, FUN. Only had to change my routine from 5nn a4 to 5nn 14 :-) Using the CW memories made it even more easy. I think it must have been a bit strange on the other side of the QSO seeing the long pause after the 5nn because the "1" takes a reletive long time in CW. That's also why a kept going on with the 5nn instead of 599. Anyway, flawless operation and I love the rtty dual passband. Very good filtering. 73, Arie PA3A _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

I think I noticed quite a few people doing this over the weekend due to the slow
transmission of the characters and the spacing. I did not have a problem copying them at all. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Mon Sep 29 11:12 , "Arie Kleingeld PA3A" sent: > >I had a few spare moments this weekend and took the CW-paddle for about >100 RTTY QSO's during the CQWW. > >Boy, that was very easy and, most of all, FUN.

Ran barefoot here, into a dipole at 40'. 2 stereo cables, a serial
cable (for band info) and ran in VOX mode. 420 Qs, 235,296 pts. Only my 3rd RTTY contest. I had never done it at all before getting my K3 in March.

Next time load your memory with 599 14 IM (dididahdah with no space between). The IM is for IMmediate end of transmission. Don't send 5NN since 599 is just as fast in RTTY and less confusing to RTTY ops. Using my paddle, I loaded: M1: W4ZV W4ZV IM M3: 599 05 NC IM (if I needed linked repetitions I just double-tapped M1 or M3). Using the memories, I was later told I sounded like regular RTTY (i.e. no delays due to CW sending speed since my memory exchanges were sent at full RTTY speed of ~60 WPM). I didn't see any point in repeating the call of the other station since I was always dead zero beat (thanks to CWT) and was responding to his CQ (i.e. not CQ-ing myself). I found the K3's CW TX decoder more sensitive to perfect CW timing than my poor fist, so after mangling my first QSO with the key I used the memories exclusively for my other QSOs. I tuned for a CQ, pressed M1, if answered I pressed M3, got my confirmation and went looking for another. My only slight confusion was when my call would appear in the buffer after answering a station. The first time I thought that was the station answering me but quickly realized it was left over in the display from my call (i.e. M1) since the DX often answered someone else in the pileup. This was my first experience with RTTY after 51 years on the air. I would never have bothered were it not for the K3. I now feel very comfortable using the above technique to call DX stations in a pileup, should the need ever arise (i.e. in case a new one should show up on RTTY and not CW). 73, Bill |

Yes Bill,
I used the IM during paddling and using the memories. If using the paddle, be sure to really send ..-- A bit too slow with the paddle and it sends IM. :-) The high speed of the memories: good idea! Implented for next time. 73 Arie PA3A --------------------------------------------------------- Next time load your memory with 599 14 IM (dididahdah with no space between).

I also worked the contest briefly. I wasn't contesting, but I was looking for Wyoming. I used my K3 along with the LP-PAN panadapter, and PowerSDR, LP-Bridge, MMTTY and Ham Radio Deluxe software. This let me set the RTTY DTF filter on the K3 and click on signals in the panadapter spectrum to tune them in. While MMTTY was decoding an exchange, I would be lining up the next signal as I hopped up and down the band.

Sending '5NN' is not recommended in RTTY because each RTTY character takes the same amount of time to send. Sending cut numbers in RTTY looks silly and somewhat LIDish. Moreover, sending '5NN' in RTTY takes FOUR characters because there is a letters-shift character sent between the '5' and the first 'N'. Therefore, sending the cut number '5NN' in RTTY actually takes 33% more time! However, in the specific case of using sending RTTY via the paddle with the K3, there is some savings in sending '5NN' because of the CW involved. The result on the other end still looks silly, so I don't think it is worth the time savings. And, in the K3 CW-->RTTY mode, there are huge spaces between the RTTY letters since few of us can key at 60 wpm. So, the savings from keying '5NN' are swamped out by the "Farnsworth RTTY" being generated. Of course, if you use the K3 message memory, then there is no savings at all from loading in '5NN'. 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
