Zo, klaar met de les… de derde sessie alweer van de CWops Intermediate CW Academy Class. Was leuk. We hebben ook nu weer veel gepraat over de lesstof. Gelukkig is er alle tijd om onduidelijkheden of de uitdagingen te bespreken.
Daarna begonnen we 4-letterwoorden naar elkaar te seinen zoals de laatste keer. Dit ging al een stuk beter en sneller dan de vorige keer. Na 4 rondes 4-letterwoorden begon advisor Bruce K9OZ een zin van 3 woorden te seinen, wie het kon nemen moest zijn roepnaam seinen en daarna de zin herhalen. Gevolgd door een zin van 4 woorden en een zin van 5 woorden. Ik kon alle drie de zinnen nemen, dus dat ging best goed. Bruce is erg blij met ons. We gaan snel……. sneller dan hij gewend is bij een klas.
Het begint echt wel zwaarder te worden nu. De snelheid gaat omhoog (13 woorden per minuut) en dat is best lastig als je even niet fit bent of moe. Ook zaten er dit keer veel langere woorden in de Short Story als Neighbours, Neighborhood, because etc…. en de QTH bij het oefen QSO: “Aguascalientes”… dat maakt het Head Copy (ICR) lastig. ICR staat voor Instant Character Recognition, het in je hoofd vormen van letters en cijfers en uiteindelijk ook de woorden. Hoe langer en ingewikkelder de woorden, hoe lastiger het wordt. En alle teksten zijn in het Engels, dus een dubbele uitdaging. Van sommige Engelse woorden in de teksten heb ik nog nooit gehoord haha…. Uiteraard komt het allemaal wel. Specifiek voor de ICR gebruiken we de website LCWO.net (Learn CW Online).
Ook gebruiken we tijdens de lesstof Morse Runner en RufzXP. Beide programma’s heb ik op de Windows laptop geïnstalleerd omdat beide niet op de iMac draaien. ook niet onder Wine op mijn iMac versie. Wel bestaat er een appje voor de iMac en dat is QRQ, als DOS kloon van de oudere DOS versie van RufzXP. En dat werkt prima al zitten er wel erg lange callsigns in die het wat lastiger maken. Ook zit er een highscore lijst in met grafiek.
Morse Runner simuleert een echte contest. Inclusief ‘soort van’ menselijk gedrag. Je kunt allerlei storende factoren instellen en toevoegen. Dit staat voor nu nog allemaal uit. Met RufzXP kun je de snelheid van callsigns nemen trainen. Het begint snel en zakt in snelheid wanneer je een foute call ingeeft. De snelheid gaat weer omhoog wanneer je de call goed hebt.
Het blijft een uitdaging. Vanaf nu gaat langzaam de snelheid omhoog naar 15 woorden per minuut (karaktersnelheid nog steeds 25 woorden per minuut).
Over the last couple of weeks, I've started participating in a little round table on 80m at 5 AM. Yikes. These group of guys are outstanding CW operators and all working on honing in on their high speed, or QRQ, operating. The average speed is in the 40-50 wpm range depending on who is there and conditions, though pretty much everyone is running (well) over 100w so conditions don't usually have much impact! I'll admit, the last few years of inactivity mixed with the intermittent keyboard-sent contests, my sending has suffered immensely. Yes, I can probably manage quick fills in a contest at 35wpm but even though I'm close to copying ragchew QSOs at 40wpm, I can't send over an extended period more than 30wpm without errors. It is a humbling and frustrating experience to be among such great ops and still feel like a complete LID! They are all very accommodating though and willing to withstand the poor fist while I improve, which is honorable.
My station has been performing very well through all of this though which is a great feeling. There has been little RFI to speak of and I've become used to relatively comfortable operations. (save the computer taking a dump on me but that's not related to ham radio) With that said, I am always looking for ways to improve the station (plus it gives me something to strive for, which is always good in life). Based on recommendation from a friend, I figured I'd try to get an antenna resonant on 60m. I used to work on 60m a bit from Iowa but it's been years since I have had any interest or reason to check it out. With its "unusual" propagation characteristics, it might be a nice change of pace from the other "low" band operations I'm used to. The Gap Titan is not resonant anywhere near 5.3 MHz so I was left with figuring out something on the inverted L for now. The inverted L is cut for 80m and does a pretty good job there but to get from 3.5MHz to 5.3MHz I'd need to add some capacitance to make the antenna look shorter. Luckily I picked up a homebrew tuner some years back at a hamfest so I had a couple of open air tuning capacitors at my disposal to do the job. I rigged up some hokey wiring and hooked it up and was able to tune a nice null a few places along the coil with the capacitor in series. It was interesting to see how I could pick different spots of resonance and get different network Q, showing a variety of usable bandwidths. I decided to pick a lower Q option so I could get the whole 60m band, and back at the operating position, the SWR stays below 1.5:1 across the whole band. Now I can operate 160, 80, and 60 meters on that antenna without much trouble. Just a few jumpers to move around. I would love to make it remote switching but that's a job for another day.
Next little project was to do some work on the Gap. My and I had a little spat regarding the beauty of my antennas (you can guess which side she comes down on) and I made a private promise to help the situation a bit. The Gap has a wire loop on the bottom part that serves as a counterpoise for 40m as well as part of the 10m element and it happens that the mast I chose for installing it was a hair too short - ok it's about a foot too short if we're being honest - to put the loop above head level. This means when walking around the pool deck, one has to duck to not hit the loop; a scenario that is less than ideal for obvious reasons. As it turns out, the shape of the loop isn't really important for operation on 40m, and at least one other ham has modified his antenna to allow for a more conventional radial in place of the loop due to similar constraints. So to help pad the concerns of the XYL, I set out to do just that. I removed the spreaders and ran a counterpoise along the top of the fence in the NE direction and pruned for a good match on 40m. Luckily I was able to find one not unlike the original match without affecting the matches on the other bands! So now I have a loop-less Gap Titan, and time will tell if it will cause any degradation in performance on 40 (or other bands).
Remember the part about the QRQ CW net in the mornings? Well that high speed, QSK operation has made it really obvious the most critical limitation of the TS-590: Relay based T/R switching. You may recall I noted this way back when I did the side by side comparison between these radios and nothing has changed in that regard. I still think the TS-590S and SG are some of the best deals in radio, especially considering the 2nd hand market for the 590S is down BELOW $700!!! It makes the value proposition against the K3 very difficult. However... if silent and smooth QSK is your goal, there is simply no match for an Elecraft radio (well maybe Ten Tec but lets not go there mkay?).... I think you can see where this is going! Upon introduction of my W6LVP receive antenna loop, the TS-590 now has TWO relays clacking away and at 50 WPM it can be quite a racket. I did make a considerable improvement in this by covering both relays with blue-tack putty (the stuff you use to hold up posters from the office supplies), but both are still quite noticeable even when wearing headphones. Those of you who know me well know I'm a real stickler for noisy stuff like this so it's just hard for me to ignore. Which has brought me to the conclusion that I have to start my journey back to the Elecraft lineup, and perhaps my timing could not be better. It just so happens that my friend N5EIL is in the process of upgrading his remote station and reducing the stack of radios he has at home and among them is a K3/10 with the sub-receiver installed. Neil made me an offer I simply cannot refuse and will let me "hold on" to the K3 for him on the pretense that I buy the 100w PA. Some time down the road we'll decide if I want to buy the whole radio from him or if he'll buy the PA from me. The only drawback is if I decide to let him have it back, I'll be stuck with my only radio being my FT-817, and I think we all know that's a non-starter! So the reality is, I'm going to end up buying the radio from him soon enough and I'll be back in the family! Someone get the Kool-Aid mix!
I'll keep you all updated as things progress but that's all for now!
