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!

The instructions from GAP suggested to use a pipe with PVC pipe over it.  PVC does not bond to concrete so the idea is that you could pull the antenna out of the concrete for maintenance.  I did not try to do this at the last house since I didn't spend enough time thinking about how that worked.  I could not find any PVC at the normal stores that would fit over any mast material but the instructions did suggest cutting the pipe lengthwise to expand it over the mast.  This go around I decided to give it a shot.  Using a standard wood handsaw, I cut the slot down the side of the pipe and hammered it onto my mast (sorry no pictures).  I then wrapped the PVC in shipping plastic - you know the stretchy stuff they wrap furniture in - and got it situated in the hole.  5 bags of quick set concrete mix and she was set.  Then came the time to attempt to pull the mast out... It moved about 2 inches then there was no more movement.  I tried everything to get it to pull out of the concrete but it was not going to happen.  Its no loss, I just had to mount the antenna the same way I did at the last house: put the bracket near the ground, tilt the base into it and then slide it up the mast to the top.  Really not all that difficult having done it several times before.  Someday I'll figure out a way to get some more upward force on the mast to free it from the concrete but not this time.

I completed the installation by installing the 40/10m "radial" loop and spreader arms.  My measurements and planning almost worked the way I wanted.  I was far enough from the fence that the hoop didn't hit anything but my mast was just too short to get the hoop above the fence, and more importantly, above head level.  I can probably find a way to lash up another mast to get the additional elevation I'm after but this will do for now.

Looks a little wonky... guys were too tight!

The last step was to install an 8' ground rod bonded to the pool equipment ground (which in turn is bonded to the panel):


Is it the most elegant solution? No. But it should provide the protection I need.  My only hope is that it passes inspection!

Be looking for operating reports soon!  I'm on the air!

This wire was attached to the bottom of the 20m element on the antenna, dangling between the spreaders for the 40m radial loop.  Apparently this little bitty stuff (and its insulation) can't handle a few hundred watts while touching other metal parts!  The insulation had burned off and caused the 20m element to short out to the 40m element.  I'm lucky I didn't burn anything else up!  I replaced the wire with some much, much heavier stuff with nice thick insulation and rotated the loop a bit so it fell evenly between 2 spreaders, maximizing the space between them.  It shouldn't happen again but I'm going to look into a more sturdy solution that doesn't rely on a flexible wire.

With that all fixed up, the amp was showing me 400w out on 20 and 40, just in time for the 0300z CW Ops mini CWT.  I ran most of the time and walked away with 52 contacts, mostly on 40.  I've been really happy with this antenna on 40m.

I still have those 527b tubes I got at Hamcom last year I'd like to throw in and test so I may do a little post on that tonight or tomorrow if I remember.

So I guess the station is primed and ready for the big contest this weekend.  I hope to hear you all on the air!

I left you last time with my entry box installed and the mast for the Gap was installed.  All that was done the week before Field Day and I wasn't too eager to try putting the antenna up myself so I let things sit for a bit until I got back.  (more on FD in another post?)

So the Tuesday after I got back from Field Day, I went out and looked at the mast and the antenna for a bit trying to devise how I'd get the antenna up myself.  My proposed help was still on the way back from FD and wouldn't be back in the area until Thursday and gosh darn, I just can't wait that long!

I was trying to think of a way to lever it up but that wouldn't work, then I got a ladder out and I thought I'd be able to set it in the mount from the ladder but that much leverage at that height was way too disconcerting so I put that idea to bed.  Finally I thought of the best way to do it: lower the bracket to the ground, mount the antenna to the bracket, then slide the whole thing up to the top.  This worked just fine!

Nevertheless, the antenna is resonant on all bands pretty well now.  The SWR curve on 17 looks really weird so I wonder if there's a loose connection or something but I'm not too worried about it as most of my operation will probably be 20m and lower during the solar minimum.

I let WSPR run on 5w for a day on 20mr and I can't say I'm upset with the results:


Hope to hear you all on the air soon!
