N1GY- The simple Approach to Ham Radio
UPDATES From The Radio Room, Page 11

Today I built a couple of Jigs to improve the construction of the PowerPole Power distribution blocks. A cutting jig makes ensuring that all the copper clad steel rods are cut to exactly the same length. A soldering jig makes sure that all of the contacts are soldered in the correct orientation and to the correct length. I built an 8 +1 and a 6 +1 powerblock and the new jigs made the job much easier. On another note, our VE group held another VE testing session today and we now have 2 more Technician class hams in the group. The other applicant apparently just did not study. There are extenuating circumstances in that person's situation, however, so maybe when the demands of school are a bit less the results will be different.

Today I tried to buy more welding rod from my usual supplier but they no longer carry it. I checked the Internet and found a welding supplier locally who had the same material in stock. Since the 10 pound size was actually less expensive than two 3 pound boxes, I of course bought the `10 pound box. The new rods are a bit different in that they have a part number stamped into each rod at both ends. This will cost me about 4 or 5 inches of each rod, but given the excellent price of the 10 pound box, I am not worried. I am going to build a couple of new jigs so that the small piecesof the welding rod will all be exactly the same length and the Powerpole contacts will all be soldered on in the proper orientation. This will take a few days and maybe a trip to the parts store but in due time another run of PowerPole power distribution blocks will be available. The fun continues!!

I have temporarily run out of my favorite 3/32" copper clad steel welding rod, so for the moment I am unable to build any more PowerPole distribution blocks. I plan on restocking the material this coming week so the soldering guns will be heating up again around Thursday. On another note a friend dropped off a slew of antique electronic parts that , I am sure, will be of much use to those hams who like to restore "boatanchors" otherwise known as classic radios.

Things are back to the usual today. My sister flew home to Ottawa, I had a great dinner with a friend of mine and a fellow ham came over this afternoon for a check-up of his radio (working perfectly) and some headscratching over the unusual static and RFI that he was experiencing at his base station. We decided that someone near his station was using a power tool with a very RF-noisy motor and he plans to search it out as time permits. We decided that because the day before his radio was working fine and the next day it was almost unreadable due to the RFI surrounding his signal. At my house the radio worked perfectly on the same day.

There is not much to report on the Amateur Radio side of things. For the past week or so I have been hosting my sister on her pilgrimage to Florida to get away from the several feet of snow still sitting on her front lawn. She seems to be enjoying herself sitting out in the sun and going shopping with her niece. The Tech net last night was almost an hour long and the attendees fielded several questions ranging from grounding to battery backup to Baofengs and even to D-Star. One participant was looking for a source for thyristors. The participants were able to either provide answers or at least point the operator with the query in the right direction. Speaking just as an operator and not as the Technical Coordinator, I think that the Tech net fills a definite need here in the WCF section of ARRL. There are lots of brand new hams who need answers to the most basic of questions, lots of upgrading hams who have questions about their new privileges on HF and about the equipment needed, and finally, plenty of older hams who need help with new modes like software defined radios and new digital modes like FT-8 and others. Some just need help finding a source for a specific part. All are invited to join in the fun on Thursday evening at 2100 Hours Local on the NI4CE linked repeater system that covers all of the West Central Florida Section.

It is time for a report on the Sarasota Emergency Radio Club Hamfest. They put on one of the best small hamfests I have been to in years. The volunteers knew exactly where to place the vendors, the food was provided by a BBQ food truck and an Icecream truck, both of which had excellent offerings and the turnout of hams was huge. I was a vendor at this one and after what I thought was a slow start I cleared a very nice chunk of cash. If they run it again next year, I will be absolutely sure to attend.
I wish I could say similar things about my little foray into special event stations. Over two hours of calling for stations and not one completed QSO. I heard one mobile unit that was too far away to be logged and he indicated that he would call back when he got closer but he never did. Since I was already tired after the hamfest in the morning, I closed up shop after two hours and went home after adding a suitable donation to the fundraiser's coffers. Ah well, better luck next time.

There is not much going on in the workshop this week. I am preparing for a visit from some of my family and for a new hamfest this weekend. The Sarasota Emergency Radio Club is holding a first tailgate and swap meet for the area and I will be there to support it and also to sell a few things that have made it out of the workshop lately. On the same day, Saturday the 23rd, I will, at least for a while, be doing a special event station at a fundraiser for St Judes Children's Research Hospital that will take place on Egret Lane in Bradenton, FL.

The new Battery Project is done. The 12 AH 12 VDC SLA battery fits perfectly between the side walls of the container. THe battery and the charger unit are held in place using double sided tape of a type used by trophy and award shops. The tape holds very well, although I would not reccomend holding the case upside down. At first I was going to separate the charging and load circuits with a DPDT switch but in the end I simply connected everything on one circuit. The one big change was to place the charger inside the case with the battery. The AC power cord for the charger has been run through the lid using different colored Powerpoles (green and black). The external cord can be stored inside the case so there is nothing else to carry about other than the radio that is to be powered by the battery. A new Page has been added to the web site to explain the new battery package as well as show an older unit of somewhat higher capacity

I am in the middle of a new little project, mainly because the two main ingredients will not get here until the 13th. This is really a simple thing to build, a battery box with a built in charger. Pictures will follow along with some text. It can be used as a primary power source for a radio like the FT-817ND or a hand held unit like an FT-60. The battery is a 12 AH 12 VDC unit and the built in charger is specifically designed for SLA batteries. Everything is ready for the battery and charger to get here. Even the brackets to secure the battery into the box are done. More later.

I have sold the 25 watt dual band radio featured elsewhere on this site. As I am trying to gradually withdraw myself from the demands of ARES deployment, I find myself with equipment that is no longer suitable for my current situation. I am also gradually sorting the chaf from the wheat in my workshop, a process which is fairly well along.

An update is in order about the scooter radio installation. After a discussion with the people at Batteries Plus I discovered that a small well behind and under the back of the seat was just the right size for a single 7 AH SLA battery. A metal strap covered in heat shrink secures the battery in place and a spliced in Anderson Power Pole port allows for recharging the battery without having to remove it from the scooter. Another extension cord looks to be in the offing. On another note, I took the antenna I built for use on a sailboat to the weekly "Burger Day" at a local restaurant. The individual for whom it was intended was blown away and now definitley intends to use it on his sailing excursion. Pictures of both projects will follow in due time.

A couple of new projects have been initiated at N1GY. The first is a dual band vertical dipole that was intended for a fellow ham's sailing experience. I would not call it an adventure, he is only sailing locally and only for a few days. I spent about $70.00 on the project but now it appears that he may use something else instead. I will show my design to him on Monday and see what his thoughts are then. The other project was a total redesign of the scooter radio set-up. I had a couple of minor collisions at Orlando Hamcation between the radio battery box and the various non-ADA compliant doors at the Central Florida Fairgrounds. The upshot was that the mounting bolts for the battery box got bent and left the box hanging even further off to my right. I decided, once I had the unit disassembled to separate the radio from the battery box, build a new battery box and mount it somewhere within the space occupied by the scooter rather than off to one sidex. That part of the project is still in the design stage, I will have more on the whole thing when I get that finished.

I have just returned from the opening day of Orlando Hamcation 2019. This major hamfest grows bigger every year. It has become almost as big as The National Hamvention in Xenia Ohio (used to be called Dayton).I have even heard that some vendors would rather come to Orlando in February than "Dayton/Xenia" in May. Time will tell who gets the top spot. In any case I did not have to buy much this year, just a few antenna mounts and some dual band whips for a soon to start project. I spent most of the day at the ARRL booth where myself and others answered questions, gave away new ARRL Calendars and pointed people in the right direction depending on what they were looking for. Lunch was nice if a bit pricy but then everything is getting more expensive all the time. The turnout of hams was outstanding for a Friday and I expect that Saturday will be even busier.

Once again it has become necessary to add another page for Updates from the Radio Room since the previous page has filled up to the bottom of the navigation panel on the left side of the page. Anything longer than that and it becomes unwieldy for the reader. I added the last entry to Page 10 today and then observed that Page 10 had hit the self imposed limit. Thus Page 11 was created. I decided to go ahead and do it now rather than wait for the next update.
