One of the things I wish I had

was the skill to homebrew stuff. And by stuff I mean circuits, receivers, transmitters, accessories and the like. Oh, I can build kits all right - although as I age, my eyes aren't quite what they used to be, and SMD components can send shivers up and down my spine when they are microscopic. I can look at a schematic and make repairs. Heck, I did that for 22 years for a living. But to look at a schematic, and take a bunch of components and build a working whatever? I'm out of my league.

I look at the creations of Dave AA7EE or Bob W3BBO and I just wistfully whistle to myself. To have the prowess and ability to build a receiver or transmitter from scratch, have it work AND look beautiful too? God didn't gift me with that kind of talent.Β  And that's OK, I guess. I just muddle around with the few things I can make, which are usually non-electrical and always would look nicer if someone else had built them.Β Β 

Which brings me to last night. I needed a solution for my American Morse DCP paddles. I took them with me to FOBB, but stopped using them part ways into the event. I was hand holding them, and my big meaty paws were causing problems. I have the tension and contact spacing set so that this thing feels pretty much like a touch paddle. The problem is that it's so small that when I would hold it in one hand and key with the other, the holding hand would mess things up by accidentally creating extraneous dits and dahs.

I want to use them for the Skeeter Hunt, but realized that I need some kind of base. That would allow me to handle it better. But what could I use? I went down to the shack and started hunting around. I didn't have any wood or metal blocks laying around that would be useful, but then my eyes landed upon and old Velamints tin that had been sitting on the shelf for years. A possibility?

I took a punch and made a tiny hole in the lid. Then I went into my parts drawers looking for a screw and nut skinny enough to go through the hole in the paddle, but long enough to reach into the case. After rummaging around for a while, i found what I needed.

I'll go to a sporting goods store on Saturday and will purchase some of those small and round split bead sinkers that are used for fishing. I'll pour a few packets into the tin and will put some tape around the edges to make sure it never accidentally opens, "spilling the beans" as it were. That should make the base heavy enough for table top use without making it too heavy.

Just like my drive on mast holder, it's no work of art, and it's no ingenious design, but it works and I guess that's all I can ask for.Β 

And perhaps I won't even get the chance to use the paddles this Sunday, anyhow. I may just be operating the Skeeter Hunt from the shack, if at all. 91% chance of thunderstorms on Sunday afternoon. Yuck!

The other place I haven't been having any luck is listening for N5J - the Jarvis Island DXpedition. When I get home, they seem to be concentrating on 15 and 17 Meters. Not only can I not hear them, I can't hear the pileup, either!

Weekend mish-mash

This weekend saw a mix of various Amateur Radio activities. Getting on HF was not predominant, although I did get on Sunday morning for a bit and worked a few POTA activations. Brave souls, those activators, because all weekend long, the Space Weather Live app was VERY active. It seemed like every time I turned around I was getting a notification of a new solar flare or a "minor" radio blackout. On Facebook, more than one activator commented about the crummy band conditions and the noticeably fewer stations that they were able to log.

Saturday morning saw our monthly VE Session. We had two candidates, one of whom upgraded to Amateur Extra. Our other candidate got his Technician class license and missed becoming a General by only three wrong answers. He got 12 wrong and you're allowed up to 9. So close! The bright side is that he saw the exam, he has an idea now of what's on it and he should have a good idea where he's comfortable with his knowledge and where he needs to study more. I predict he'll be a General class Ham within a month or two.

On Sunday morning, I made the additional "modification" to my drive on mast holder. The lid hinges that I ordered through Amazon were delivered on Thursday. They did the trick to a "T" - or maybe I should say to an "L". HI!





The hinges lock in and brace the two boards at a 90 degree angle, just as I need them to. In fact, this configuration is so stable that in a pinch, any heavy weight will suffice, such as a heavy rock, or a cinder block, or a sand bag or something like thatΒ  It's an ideal drive on mast holder, and while a vehicle is certainly preferred, it's not absolutely necessary. Conceivably, with a heavy enough weight, I could use this in the field on Field Day would no longer have to mess with the PVC holder that uses the tent pegs and CamJams. That would be a time saver! The only prerequisite is that I'd have to find a location flat enough to place this on so that it's not leaning in any one direction too much.

BTW, before you ask, the 4 holes in the horizontal board are there to give the protruding U-Bolt threads and the nuts the space they need so that when collapsed, this contraption can lay totally flat and not wedged.

Other than that, the weekend was occupied with the normal weekend chores and duties. Hope you had a good weekend and I'm looking forward to the Skeeter Hunt next Sunday!Β 

Tonight we have a CERT training session with the NorthStar helicopter. NorthStar is the helicopter owned and utilized by the NJ State Police for the northern half of New Jersey. (SouthStar covers the southern half of the state). It is used primarily for transporting medivac patients to wherever they need to go depending on the circumstances and extent of their injuries. The session tonight will certify that we've been properly trained on procedures and safety requirements, so that we can approach the helicopter and assist with loading and unloading victims should it ever become =necessary.

Some refinements needed

Regarding the new mast holder.




Since the Jackite mast is kind of free floating within the PVC, this version is not quite as stable as the older one, but it is more convenient to use. It folds flatter and I need not mess with wingnuts anymore. With the old version, the Jackite was secured directly to the vertical board and acted as its own stabilizer.Β  The problem is that I keep this in the trunk and on the old version, the wingnuts would vibrate loose over time and get lost - probably went to the same place that socks missing from the clothes dryer end up.Β  I had to replace them several times and that was a pain in the keister.

With this version,Β  I'm not satisfied that the mast leans in towards the vehicle. So I ordered two lid hinges from Amazon. That will allow me to unfold and lock the vertical board at a proper 90 degree angle, while still allowing me to re-fold it back flat again.. Convenience always comes with a cost, I guess. Other than that, it termed out pretty well, and I'm satisfied with it ......or rather I will be satisfied with it once I attach the hinges.

Regarding the oldie but goodie.

I'm going to fabricate another drive on mast holder like I had before. This time, I'm going to make it slightly smaller so that it eats up less space in the trunk. I'm also going to make a change. Instead of holding the Jackite by the U-bolts, I will use them to hold a section of PVC. This way I don't have to continuously tighten and loosen wing nuts. I will be able to just slip the Jackite into the PVC.Β  It will function exactly the same way, with a few cosmetic changes. I never had a problem with the old one not working properly. It was just a bit too big.


I went to Home Depot last night and got the materials that I needed. I ended up spending $22. The hardest part was finding two of the same sized u-brackets. They're in open bins and people must take them out to look at and then don't return them to their proper place. It was a jumble! It may not be elegant, but it's sure a lot cheaper than the commercial solutions out there.Β  (My boss at Sinar Bron, Ulrich Krahenbuhl, was an engineer. He always loved "elegant" solutions.)

I was going to try Craig WB3GCK's version, but the only lengths of galvanized pipe that they sell are 10 feet long. I only need a three foot section and not only do I not have a good enough pipe cutter, but I would also have no use for the remaining 7 feet. Seems like a waste to just throw it away. In any case, I should have plenty of time to build it this weekend, as scattered thunderstorms are predicted for both Saturday and Sunday - throughout the day and evenings - the culmination of yet another hellacious heatwave!

The other thing I need to do is to unpack and check out a purchase that was delivered the other day.


And I'll have to drop off the big (dead) battery at the metals recycling place in town. This battery has the BMS system incorporated into it. After communicating back and forth with the seller, he confirmed I can use the ACME battery charger that I presently use. He informed me I need to be watchful that once I get an indication of full charge (LED changing from red to green on my charger) that I unhook it and not let it go into a trickle charge state for a prolonged period of time. I never leave charging batteries unattended in our house, anyway. I'm too paranoid about something blowing up or catching fire to do that.
