Easy to hang dipoles!
KD3Y posted a topic in Ham topics in general,
I could only get my 40 meter dipole up 26 feet in the pine tree because thats as far as I could sling the string with the fishing weight on it. Took me about 15 tries and I almost put my eye out. Got tangled up twice, broke the string trying to get it loose, and the weights are still up there hanging in the tree. But them limbs up there 60 or 70 feet up sure are appealing. I just didn't have a way to get my rope that high. I bet my dipole would perform a lot better at 70 feet than 26.
SO... I got my drone license so all I have to do is tie a string to the hook on the belly, and fly it over the branch I want the dipole leg to secure to then land the drone. Once the smaller string is over the limb I can tie the larger rope on the end of the dipole leg to it and pull it over the limb. Why is it that everyone in the club all of a sudden has a dipole they need hung???????

POTA on Vancouver Island
WA3LTJ posted a topic in POTA,
The weather was just warm enough to operate outdoors. I used a 20 m dipole at 25 ft and a Yaesu FT-891. The power was a 20 Ah LiFePO4 battery. 71 QSOs in 2 hours. QSOs included MT, UT, WY, SD, CO, OR, OH, ID, AK, MN, NV, KS, CA, AZ, MI, KY, TN, PA, WV Saskatchewan, Alberta, B.C. Background noise was very low, so I was operating at the limit of the internal S/N of the radio. The staff at the gate to the park were very friendly and a little familiar with ham radio.

When it all goes down
KE8HNK posted a blog entry in KE8HNK's Blog,
"All second shift standby for an emergency announcement"
A few seconds go by and another announcement's made.
"due to civil disrest we are asking all second shift employees to stand by with third shift until further notice at which time we will provide further information"
Now you know that there had been some peaceful vigils and protests going on in the downtown area, but nothing to crazy, however once you flip on the news channel you find out that a few bad eggs decide to start a riot to the south of downtown. So you call your family and tell them to lock the doors and stay in the house. You know your wife or Fiancé's kids are at a restaurant nearby and you call her and say " Babe get a hold to the kids and tell them to get out of the area".
She responds why? As she has been asleep and didn't know what is going on.
You respond they are rioting to the south and I know- CLICK all of a sudden your phone shuts off.
You desperately try to call her back but you get the message " All circuit's are busy try your call again later"
A few minutes later during a press conference you find out that the city had shut down cell phone service for 8 miles around downtown to help quell the riot's. You and your family live within the 8 mile range. You worry that your message didn't get through and you fear the worst as you watch the live news reports from your desk computer.
What do you do next?

Homogeneity
K3MRI posted a topic in Ham topics in general,
Is it just me or are we reinforcing the message that to be an amateur radio operator you have to look like 'me'. I look like I fit in that picture; I just wish I did not look like 95.65% of those in the image. I would hope that in years to come, the diversity and youth bugs bite us, because if they don't...

Ropes and Accessories
Katerina01 posted a blog entry in Knowledge,
The difference stands in parameters. Ropes from the Classic product line are the basic ropes optimized for a good price to performance ratio, whereas type M has approximately doubled strength and simultaneously half the stretch compared to type Classic. They are also lighter because the rope core is made from high-strength Dyneema® fibers.
When is it better to use Premium rope (M) instead of Classic?
When one needs the lowest weight and wind resistance (long ropes holding wire antennas, or supporting large beam elements, or expeditions where low weight is crucial). Also when the anchor points on the ground need to be placed close to the tower (less than 50% of the anchor height – depending on the type of tower – the higher stress needs to be calculated individually) and finally, for any big towers with big antennas.
When I am looking at Dyneema ropes for maritime use, the strength eg. with 10 mm Dyneema is well over 10.000 kg, but your Mastrant M rope with a similar diameter has "only" 3850 kg strength, even the core material is the same. Can you explain why?
There may be several reasons for this difference. The first is that in Mastrant-M ropes, HMPE fibers form only the core. The braid (and any intermediate braid) is made of Polyester fibers, which have lower strength (but other necessary properties for which they are used). The reason may also be the methodology of measuring strength. Our declared breaking strength of ropes is strength really measured – each production series. It must be always 3% or higher than in our specification. There on the market is also another approach – the theoretical BS calculated based on the specification of Dyneema fiber and number of fibers (diameter). This theoretical strength is always much higher.

Shulman Auction
K3MRI posted a link in Classifieds, auctioneers,
In 2013, after a successful live gallery auction featuring only ham radio equipment, David decided to test the waters in the online world with ham radio gear and antique radios. From that point on, and 8 years later, Schulman Auction has grown into one of the only online auctioneers specializing in only this type of equipment along with vintage audio.
Growing up, David had a fascination with vacuum tube-based electronics and thanks to his mentor during those early years, he received his amateur radio license at the age of 14. David is still actively licensed as an Extra class operator today.
David’s expertise in the auction business for the past 19 years, combined with that of 40 plus years in amateur radio, has set the stage for what Schulman Auction has now become. By utilizing an online auction platform, and tried and true auction marketing techniques, Schulman Auction will market your items or collections to a targeted worldwide audience. All of this in a timely and cost-effective manner.

CTR2-Mini
KU7Q posted a topic in Self-promotion,
I redesigned CTR2-Mini to be much simpler, easier to build, and a lot cheaper.
Here's a few photos of the unit. The first shows the right-hand version. I can supply a left handed enclosure if that works better for you. The second photo is the small Radio I/O interface that connects the Mini to your radio. For size reference those are 1/8" phone jacks and a CAT5 connector on the board. The third photo shows two Minis in a dual enclosure with their Radio I/O units. The last photo shows two Minis operating an FTdx101 in Dual VFO control mode. The Mini on the left is controlling the Main VFO and the one on the right is controlling the the Sub VFO. Only one CAT connection to the radio is required. The Minis can be located anywhere in your shack (I like them just in back of my keyboard) so I can easily change radio settings. The Mini works with many other radios including FlexRadios where you can have one Mini controlling each slice in the radio. Of course the Mini includes a contest keyer too.
You can read more about the Mini in my blog, https://ctr2.lynovation.com I also have a YouTube channel, https://youtube.com/lynovation where I demonstrate the various features of the system.
I can supply PCBs with the SMT components pre-installed for all the boards in this project. I can also supply assembled acrylic stands as shown in the photos. I have project lists on Mouser that allow you order all the through-hole parts and the Wio Terminal to build the project with just a couple of clicks. I can also supply custom built, complete, tested, ready to use systems if you don't want to build your own.
In addition to the Mini I'm working on a companion antenna switch controller that can control single and dual port antenna switches and an SO2R controller that shares mics, headphones, paddles, function buttons, and a remote PTT switch between two Minis and their radios. The information on those options is also on my blog.
Let me know if you have any questions,
73, Lynn, KU7Q
