Loaded Some Black Powder Shotgun Shells
Last weekend I primed 25 Magtech brass 12 gauge shotgun shells and on my lunch break today I finished loading them. The details:
- Magtech 2.5" all brass hull
- CCI Large Pistol Primer
- 80 grains of 2Fg Goex black powder
- 11 gauge nitro card (over powder card)
- 11 gauge fiber cushion wad
- Lubricated felt wad
- 1 1/8 oz. of mixed No.7.5 shot
- 10 gauge overshot card
- Sealed with Duco cement
Magtech hulls require the use of oversized components because the case walls are thinner than 12 gauge plastic or paper hulls.
The felt wads were punched out of 1/8" thick wool felt with a .75" punch, then soaked in a mixture of 50/50 beeswax/mutton tallow. This is to help keep powder fouling soft.
The shot is a mix of plated that I bought from Rotometals, along with some unplated shot scavenged from miscellaneous promo loads. No. 7.5 shot is primarily for clay busting but it will work on doves, as well. Otherwise I'd load No. 5s for small game hunting.
I'll let the Duco cement cure overnight before boxing them up.
These will be good for informal clay target shooting. They shoot well in my Russian-made Baikal MP-310 over/under. Cleanup in a chrome-lined smoothbore isn't bad.

New Generator and Excellent Customer Service Experience with Amazon
The week before Labor Day, my electrician finally completed installation of a generator transfer switch in my house. Afterwards, he saw the Champion generator that I'd bought on sale at Cabela's several years ago and pointed out that I needed one that outputs 240V, so that I can power both legs of my home's wiring. The Champion puts out 120V only.
<sigh>
I will be donating the Champion to a friend's Civil Air Patrol squadron, which can use it for a mobile communications center they are building.
So, last week I ordered a DuroMax XP4850EH dual fuel (gasoline/propane) generator from Amazon. A friend has this model, has used it during power failures, and recommended it. It was about $707 on Prime and came on Saturday.
For anyone in CA, it's CARB-compliant, BTW.
It arrived damaged. One corner of the box had been smashed in then taped up. Upon inspecting the generator, a sheet metal cover was dented and the frame was scuffed. Nothing major appeared to be broken, so I went ahead and installed the wheels and feet.
Yesterday I added 20 oz. of 10W30 motor oil, connected the battery, and connected a propane tank for a test run. It fired right up. At least on propane, it seems a little quieter than my old Champion, which is nice.
Afterwards, I was able to get ahold of a human at Amazon, explained the situation, and asked for a credit since it was a scratch and dent. I did not ask for a specific amount. After waiting a few minutes on hold, the CSR came back and offered me a credit of $262.55, with the option of an Amazon gift card or putting it back on VISA. Heck yeah! I told her to put it back on my VISA.
My plan is to primarily rely on propane to fuel the generator. I can keep a few propane tanks around easily. Propane has an indefinite storage life and isn't as messy as gas. It doesn't pack as many BTUs as an equivalent amount of gasoline and the generator's output is lower with it, but if I know a hurricane is coming I can also go out and fill a couple of five gallon jerrycans with gas. The longest power outage that we've had that I can recall was about two days. <knock wood>
But I have an even better story from a friend. About 5 or 6 years ago, he bought a generator from Amazon. When it arrived, it did not work. This was during the holiday shopping season. He contacted Amazon to do an exchange and they told him to just keep it, and then they sent him a replacement.
He did some googling, figured out what part he needed to fix the bad generator, and got it up and running for $12.
He wound up with two generators for the price of one + $12.

Keeping my Nissan Xterra on the Road
Last Saturday when I got up to our campsite in Tioga County my two friends who I met onsite smelled antifreeze from my 2007 Nissan Xterra after I pulled into camp. My sense of smell sucks, to put it mildly, and I didn't smell anything. We popped the hood and after the engine cooled down, checked the antifreeze level. Sure enough it was low. One of my friends had a gallon of premix so we topped it off. (Given the age of the vehicle I should have been carrying some.)
We also noticed that a hose going from air cleaner to the engine was cracked. I'm now carrying some Rescue Tape (self-fusing silicone tape) in my truck toolkit in case any other hoses crack.
The joys of owning an older vehicle. 😐
Yesterday, I brought the truck to a local mechanic who confirmed that it has a leak, so I had him replace the radiator. It must have been a very small leak since the truck didn't overheat either way on the trip (about 240 miles each way).
I've actually been thinking of getting this done to prevent the Xterra Strawberry Milkshake of Death from happening, anyway. The Xterras were designed with an automatic transmission fluid cooler integrated with the radiator. Unfortunately, sometimes there's a failure which allow cross-contamination between antifreeze and ATF fluid, causing the SMOD, which kills the transmission. It's both a clever and dumb design.
Although my truck is 13 years old it only has 110,000 miles on it, so I'd like to keep it for several more years, therefore replacing the radiator is worth it to me.

Black Powder 20 Gauge Shells with Patched Round Balls
Today I loaded up 25 rounds of 20 gauge shells for potential use as short range deer hunting loads. They consist of:
- Magtech brass cases
- Federal large pistol primers
- 80 grains of Goex 2Fg black powder
- Ballistic Products nitro card
- Ballistic Products fiber cushion wad
- 2 x 0.010” patches prelubed with Wonder Lube
- .575 round ball
- Ballistic Products over shot card sealed with Duco cement

Black Powder Shotgun Go Boom!
(The picture is a frame grab from an iPhone video.)
I did a few variants:
1-1/4 oz. of #7.5 shot on top of a compressed column of sawdust (in lieu of a cushion wad)
1-1/4 oz. of #5 shot on top of sawdust.
Also, some of the same payloads on top of lubricated wool felt wads. (I have a supply of such homemade wads for use in my Euroarms Magnum Cape Gun percussion 12 bore.)
And a patched .690 round ball on top a couple lubricated felt wads. All were loaded on top of 80 grains of 3Fg.
I tested one each of the #7.5 and #5s, and 3 of the PRB loads.
From 10 yards the #7.5 penetrated one wall of an empty soup can. The #5s went through both sides. Patterning seemed OK for a cylinder bore gun.
Accuracy with the PRB would be good enough to take a deer out to 40 - 50 yards or so.
Because these shells were loaded with black powder, I ran a couple patches wet with a Ballistol/water emulsion through the bore when we finished shooting. I repeated this at home and left the bore with a good coat of Ballistol.
The empty shells got put into a soapy water bath overnight. I found that a 12 gauge tornado brush was perfect for brushing out the inside of the cases to remove residue left from the glue I used to hold the over-shot cards in place.
Tomorrow I'll punch the primers out of the spent shells and clean the primer pockets. I'll also use some acetone to remove the load info I'd written on the side of the shells with a Sharpie marker.
Shooting these BP shells was a lot of fun and the cases should be reusable more or less indefinitely.
One thing I like about the Magtech brass shells is that they use large pistol primers rather than 209 shotshell primers. I use LPPs for .38 WCF and .44 WCF, so that's one less component I need to stock. Also, in normal times, pistol primers are less expensive than 209 primers. (All bets are off in this election/pandemic/civil unrest year, however.)

NanoVNA Vector Network Analyzer
Wikipedia has a good explanation of SWR and why it's important.
I finally got around to trying it out today. I used it to take SWR measurements of the Ultimax 100 end-fed antenna that's on my roof.
On 80 meters, SWR hovered around 2.5:1.
On 40M, SWR was around 1.7 - 1.8:1.
On 20M, SWR was around 2.5:1.
And finally, on 6M, it ranged from about 1.25 to 1.28:1.
The NanoVNA was connected as the antenna presents to my LDG IT-100 tuner: antenna-feedline-passthrough panel-patch cord.
When I checked the Radiowaz 40M dipole that I strung recently, SWR was much higher on 40M. It should be better when I get it elevated more.
The NanoVNA is a very cool and potentially useful device. However, like a lot of things that rely on open source, documentation can be spotty. The unit came with some calibration info, but nothing on how to use it. Some documentation sources to check out:
- There is some documentation on nanovna.com.
- SimpleScout's Noobs Guide to Measuring SWR with the NanoVNA on AR15.com.
- W2AEW has this excellent video on how to sweep and antenna's SWR and optimize tuning.

RTL-SDR Blog Dongle v3
This is a replacement for an older SDR dongle that I've had for several years. The thing that attracted me to this one is that you can use it to monitor HF in direct sampling mode, without an upconverter. My older dongle could only do VHF and UHF.
One nice feature of this dongle is an aluminum case. These things get hot and the metal case acts as a heatsink. That said, I may fab something to increase the surface area to improve heat dissipation. (I have a mini-mill that may come in handy for this project.)
I installed the SDR# Community Package on my HP laptop running Windows 10, and started playing with it.
This screenshot shows it tuned to KYW 1060 AM, the Philadelphia AM news station. For this I connected it to an Ultimax 100 40M - 6M end fed antenna that's on my roof.
The second screenshot shows the dongle monitoring the 2M ham band, tuned to the W3OI repeater in Allentown, PA during their Monday night net. I am located outside Philadephia in SE PA, about 42 miles away from the Allentown repeater. The terrain isn't flat between here and there, plenty of rolling hills between my home at the repeater.
The antenna for this exercise was my Comet GP-3, which is attached to a five foot mast strapped to my chimney. The tip is probably around 30' to 35' up. It's been up there for about 15 years and I cannot recommend it highly enough.
Future plans for this SDR include trying DSDPlus to try decoding digital modes, and possibly connecting it to a Raspberry Pi and accessing it over my LAN.

How to Use a Digital Multimeter
RT Systems Programming Software for the Icom 7200
The popular open source program CHIRP will talk to the IC7200. However, functionality is pretty minimal with this radio. For example, it works with the rig in live mode with changes you make in the application immediately written to the radio. It also misconfigured some fields in the memories, as I discovered later.
Years ago, shortly after buying the rig, I'd purchased RT Systems' WCS-7200 programming software on CD from the New Castle, DE Ham Radio Outlet store. That CD disappeared, along with the product registration info. So, I decided to drop $25 for a new digital download of the program. (What the heck, it's good to support small businesses anyway.)
Unlike CHIRP, it runs only on Windows, but it can use the same USB A-B cable used for digital mode operations.
The WCS-7200 software is more mature and full-featured than CHIRP. For example, I entered in a bunch of frequencies into the spreadsheet-like UI, and it then allowed me to select a group of them and move them up or down for organization. It also has a Comment field, which I used to identify which frequency is for, for example "20M PSK31" or "WWV."
Unlike CHIRP, it doesn't operate in live mode, so I could tinker with memory organization, save the file locally, and then upload it to the rig.
Before closing the app I exported the memory to a .csv file in the Ham Radio folder I keep on Dropbox, opened it in Numbers on my Mac, and printed out a copy for reference.
I still like CHIRP for programming my Baofengs and it seems to work fine with my Yaesu FT-7800R, but in this case, it was worth $25 for the commercial software.
Incidentally, a good source of frequencies to input into your radio for making contacts or just monitoring is Bandplans.com. Also check out Repeaterbook.com and RadioReference.com.

Radiowavz 40M Dipole Antenna
Hams know that antennas offer better performance when erected in crappy weather, ideally a New England winter day. Not having one of those handy, hopefully a hot-as-balls SE Pennsylvania day will suffice.
It's currently supported on both end but not the middle, which as you can see, sags a bit. The end supports are 5 foot lengths of schedule 40 PVC pipe with an eye bolt on the end. Braided dacron cord is strung through each eye bolt and then secured to the end insulators of the antenna with a bowline knot. The halyards are then attached to a large plastic landscaping stake in the ground.
The feedline is a 25 foot piece of RG-8X coaxial cable running to an MFJ-4602 window pass-through panel.
After it was up and connected I texted a couple friends and we tried it on 80M phone using NVIS propagation. I was able to hear them but they could not hear me, which wasn't surprising.
I'd like to get the middle up higher so I'm going to look into a military surplus fiberglass mast. If I get the center elevated the resulting antenna will be an inverted-V, which will give me better performance.
I haven't made any QSOs on this antenna yet, but this screenshot from pskreporter.info shows the results of calling CQ with 50W on JS8.
And this one from WSPRnet.org shows the results of transmitting 50W on WSPR.

Useful Info: Making Use of the MOLLE Bandoleer
Making Use of the MOLLE Bandoleer
In the current widespread unrest, in which AntiFa is threatening to come out from the cities to the 'burbs, it behooves you to have a defensive rifle and supporting accoutrements. A bandoleer is an inexpensive means of having a grab-and-go supply of reloads at low cost. Even if you're setup with a full plate carrier, a bandoleer would be useful to go along with hand-outs, if that's something you maintain.

Powerwerx Inline DC Power Analyzer
From the Amazon description:
- Measuring capacity up to 60V and 100A.
- 12 gauge wire with Powerpole connectors.
- Bright blue backlit LCD display.
- Measures 8 electrical parameters: Amps, Volts, Watts, Amp-hours, Watt-hours, Peak Amps, Minimum Volts (Sag), Peak Watts.
- No configuration, works automatically!
Unless you dedicated battery pack with an integrated meter, this is a worthwhile addition to a portable ham radio kit.

HP Laptop for Emcomm, First Impressions
My specific interest is in digital mode communications, which requires either a mobile device or a computer to connect to the radio and run various applications. For field ops in the past I've used an iPad and an MSI Wind netbook. I traded in the iPad a year or two ago and the netbook is ancient at this point (plus has a small 10" screen) so I wanted something better.
My normal computer is an Apple MacBook Pro. However, I am not enthused about bringing a $3,000 laptop into the field, plus it seems like a lot of ham apps are better supported on Windows or Linux.
So, Friday after work I went down to Microcenter and picked up an HP 15-ef1072nr 15.6" laptop running Windows 10 Home for $400. The specs are decent for the price, IMO:
- Dual-core AMD Ryzen 2.6 GHz CPU
- 8 GB RAM
- 256 GB SSD
- AMD Radeon 3 graphics
As expected, the hardware feels a lot cheaper than my MacBook Pro. The Mac's case is machined from billets of aluminum. The HP's case is plastic. The keyboard is mushy but usable. The screen is nowhere near that of the MacBook Pro. Overall, the HP is much lighter than the MBP, which is nice.
Battery life seems good. It was partially charged when I brought it home. I plugged it in while setting everything up but then rant it down to around 10% over the course of several hours with web browsing, YouTube, and email. I repeated that on Saturday and probably got a good 7 hours before it went into battery saver mode.
The huge trackpad on the current MacBook Pros really spoils you and it is missed on the HP.
The HP's space bar is annoying. Pressing it towards the right end doesn't do anything. I tend to press the space bar with my right hand so this is a PITA and hinders typing.
Of course, one of the things I had to do was get Windows updated. Compared with Apple's macOS updates, Windows Updates remains a major PITA with multiple reboots required. Overall, it takes a lot more time.
It has been quite awhile since I used a Windows PC for desktop computing although I ocassionally have to login to a Windows server at work so the UI isn't totally unfamiliar.
Anyway, after cleaning up some of the factory-installed bloatware I loaded a number of utilites to make life easier:
- Notepad++ (In which I wrote most of this. On Mac, I use BBEdit.)
- Piriform CCleaner
- Piriform Speccy
- Replaced the pre-loaded Office 365 with Office 2019 Pro Plus
- Visio 2019
- Google Chrome
- iCloud for Windows so I can sync bookmarks with my Mac and iPhone
- nmap
- Wireshark
- Windows Subsystem for Linux with Kali Linux installed
- Signal
- ZOC terminal
And these ham radio apps:
- Fldigi
- JS8Call
- WSJT-X
- Chirp (For programming my Icom 7200, Yaesu FT-817ND, and Baofeng HTs)
The two Apple applications I'll miss most when using the HP are Messages and Facetime, neither of which are supported on Windows.
Incidentally, Microcenter limited the number of people in the store at a time, you had to wear a mask, and before going inside you had your hands sprayed with sanitized by an employee. Also, they are not taking cash, only credit or debit cards.
Testing a New Laptop for Ham Radio and WSPR
Anyway, today I was configuring the HP to work with my Icom 7200 using Fldigi, JS8Call, and WSJT-X, and tried out transmitting using the latter in WSPR mode. The antenna was my Hawaii EARCH 40-6M end-fed, strung approximately horizontally out to my back fence. This is far from optimal.
I transmitted on WSPR at 50W a few times and checked propagation using WSPR Watch on my iPhone. Not bad.
Along with a couple friends I'm heaing up to Tioga Country next weekend. We're all hams and off-grid operations are on the list of activities. One thing I want to try is a random-length loop antenna using welding wire, connected to my antenna tuner using an LDG 4:1 balun. My friend did this a couple years ago and it worked great, allowing him to check in on a north PA/south NY 160M net.

NOCO Jump Pack
My daughter was at the neighbor's playing outside with their daughter. She called and asked if I knew how to jump start a car, because her friend's older brother's car wouldn't start. It's been a long time since I've had to jump a car, but heck, I'm Gen-X and we know these things.
I went down the block to meet them. His car was an older Toyota RAV4 and when asked, he didn't know how old the battery was. It had died without the lights or accessories being left on, so I told him it's time for a new battery but we would try to start it.
Back in 2018 I bought a NOCO Boost Plus GB40 1000 Amp jump starter pack on sale from Amazon. Since then I have kept it in the back of my truck, taking it inside a few times a year to top off the charge. This was the first time I've had to use it.
I connected up the unit and let it charge the dead battery for about 30 seconds then had him start the car. It fired right up, whereupon I disconnected the jump pack and told him to keep the car running for about 20 minutes.
The jump pack worked like a champ and I'm glad to have it. The only thing I didn't care for is that it doesn't come with a decent storage case, so I bought one of these separately.
As far as I'm concerned everyone should keep a jump pack in their vehicle. They are a lot more convenient than jumper cables, not to mention you don't need another vehicle. The lithium battery powered units don't take up much space and retain their charge for months.
This is where I get to make fun of Millenials: The guy who's car I jumped is obviously one, in his 20s, and asked me how long his battery would be good for after I charged it. He didn't know that as long as the engine is running there's a part called an "alternator" that charges the battery.
I'll give the kid a break, because he was wearing a volunteer firefight shirt, which means he's no wimp.
However, with a lot of kids growing up in fatherless households not learning how to work on cars, coupled with the complexity of modern cars that discourages a self-repair work, a lot of Millenials and Zoomers never learn how cars function. To them, it's just an appliance.
Driver's education courses really should include a basic education on how cars work and emergency procedures like how to jump start one and change a tire.
