The Hustler 4BTV is up and running!
This past weekend the IARU world contest was in action and I planned to enter the CW category. The contest morning started just fine for me BUT in the corner of my radio room, a boxed Hustler 4BTV was calling my name. The weather outside was great, the mounting base was installed and the ground radials (all 30 of them) were also installed. As I was making CW contacts my mind at the same time was spinning. The weather here has been sunny and clear for very few days and the upcoming week looked once again rainy. The same little voice in my head was telling me " Mike a contest situation is great for testing a new antenna"
Well, a few hours into the contest I jumped off the operating chair and decided it was time to finish the 4BTV install! The little voice in my head had won out. Just the day before I had marked the antenna tubing with the rough measurements for length setup between sections. The only thing left was to put the section together and tighten things down with the provided screw clamps or as I call them hose clamps.
Copper paste |
I did purchase copper paste to use on the pipe-to-pipe connection for good connectivity and help stop corrosion. In no time the antenna was together and ready to be mounted on the ground pipe. I was delighted with how light this antenna is, making it easy to lift and install.
The initial SWR was somewhat close to what was written in the DX Engineering manual, there was just some fine-tuning that needed to be done. I wanted my configuration to be in the CW area of the bands. Thank goodness I have an antenna analyzer, this made very short work of fine-tuning the antenna. I will make another post regarding the details of the SWR and adjustments.
Once the antenna was set up SWR-wise in the area of the bands it was
Marking the antenna sections |
off to the contest again to see how it stacks up to the Endfed antenna I have been using for 2 1/2 years. Using the new antenna I started calling (CWing) "CQ CONTEST" and I was pleasantly surprised with the results. Now having said that this was the first time using the antenna so a fair comparison would be over the course of a month or so with varying propagation conditions.
More to come regarding tuning, assembly and results.

2022 Colorado 14er Event (Summits On The Air)
August 5 to 8, 2022
Friday to Monday
www.ham14er.org
Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Join in on the fun during the annual event and see how many of the mountaintop stations you can contact. Be aware that many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.
This event is normally held the first full weekend in August. Following up on the success of the 10-day W0C SOTA event in 2021, in 2022 we will add two bonus days to the Colorado 14er Event. The main two days remain Saturday and Sunday (Aug 6 & 7), while the bonus days are Friday Aug 5 and Monday Aug 8th, for those SOTA enthusiasts that need more than two days of SOTA fun!
The 14er event includes Summits On the Air (SOTA) peaks, which includes over 1800 summits! If you aren’t up to climbing a 14er, there are many other summits to choose from (with a wide range of difficulty). See the W0C SOTA web page at w0c-sota.org.
Important: The recommended 2m FM frequencies have been changed to 146.58, 146.55, and 146.49 MHz, to align with the use of the North America Adventure Frequency for SOTA (146.58). The National Simplex Calling Frequency (146.52) may be used as appropriate. See the operating frequencies page.
See the very cool Colorado 14er Event gear available at https://www.cafepress.com/mtngoatwear
Radio operators who plan to activate a summit should post their intent on the ham14er group via the ham14er groups.io website. Also, be sure to check out the event information at http://www.ham14er.org
For a complete list of suggested HF, VHF, and UHF frequencies see this web page.
And there is more!
On the same weekend, SOTA enthusiasts in Montana, Idaho, Washington, and Oregon will activate summits for the Pacific Northwest Not-Quite-Fourteener (PNW-NQF) event. Also on the same weekend, the Southern California SOTA group will hold their SOCAL SOTAFEST. So there will be plenty of SOTA stations to work that weekend.
Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.

SEPAR Mobile Cruise-In
Come show us yours...
Many Amateur Radio licensees have home stations where the hobby is practiced for fun, contacting similar stations all over the globe, but the hobby has a serious side as well. We provide emergency communications where all other systems, such as cell phones or even radio towers fail. Many of us have mobile stations (in compliance with distracted driving regulations) that permit us to operate wherever and whenever. Mobile Amateur Radio is not restricted to cars and trucks but bicycles, even pedestrians and equestrians. This type of broad-based community availability requires no commercial infrastructure, hence the slogan: “ Amateur Radio works when all else fails”. This has been shown time and again all over the world.
SEPAR would like to host a first ever event of its kind locally. We have a commitment from the Surrey Fire Service and I expect that support from our contacts at the Surrey RCMP (or Surrey Police Service) to judge the entries. Prizes will be awarded for the neatest installation and the most bands covered.
The idea for this local event originated with the Portage County Amateur Radio Service (PCARS), a Wisconsin group who have been doing the Mobile Cruise-In for twelve consecutive years. Their turnout varies with the weather, but in past years they've had 50 or more entries. In addition to the entrants and Amateur Radio spectators, we welcome members of the public to stop by and check out the goings on. They say that it's a great way to generate some exposure for Amateur Radio and our emergency programs.
We appreciate the support of the A&W restaurant at that location but, if you are not an A&W fan, there are several other refreshment options adjoining the same large parking lot.
So polish up your mobile rig, dust off your Grab ‘n Go kit and come show it off at the ‘Cruise-In’

LHS Episode #473: The Weekender XCIII
It's time once again for The Weekender. This is our departure into the world of hedonism, random topic excursions, whimsy and (hopefully) knowledge. Thanks for listening and, if you happen to get a chance, feel free to call us or e-mail and send us some feedback. Tell us how we're doing. We'd love to hear from you.

Hustler 4BTV continued.
The days finished product |
Once again we had a nice weather friendly antenna installation day on Monday. It was time to run the coax out to the vertical antenna mounting pole. I chose to run RG8X coax, the main reason for this was I had lots of it on hand. From the house to the the vertical I dug a trench about 16 inches deep and I was fortunate the ground was nice and soft and tree root free.
The RG8X coax was placed in 3/4 inch PVC electrical pipe and at each end for the PVC pipe I affixed ENT tubing. This is very hardy plastic tubing that usually is encased in concrete and used to pass electrical wires in. Now you may wonder why I did not just use ENT for the complete job? The main reason is I had PVC pipe on hand and ENT here is either sold in 10 or 30 foot rolls. If I chose 30 feet I would have a majority of it leftover and ENT is pricey as well.
I now attached the base section of the Hustler 4BTV to the ground pipe but before doing so I ordered from DX Engineering the SO-239 add on kit. This is a fantastic kit made of stainless steel and allows a PL-239 connection and it can be mounted in 3 different directions. Also for all the connections I picked up some pure copper anti seize compound. This allows great connectivity and also very good for all stainless steel connections.
As an added precaution I wrapped the screw located on the bottom of the 4BTV antenna with self amalgamating splicing tape. I also wrapped the PL-239 connection with the same tape. I find water has a way of getting in at the most inconvenient times so I like to make it very difficult for this to happen.
My next step is to install the radials and tomorrow the weather man is telling me it's a great weather day to put down some radials.

Neophyte Twins – An Update
Blog readers may recall my last two construction projects, the ‘Neophyte’ 1-tube regenerative receiver and a matching ‘Neophyte’ 1-tube crystal-controlled transmitter. The receiver turned out to be an exceptionally good performer once some slight tweaks were made to the original design published back in 1968.
