Does anyone have an operational 30-50 amp 12vdc power supply they would like to sell for use in a ham shack?

Re: Can I use a duplexer / triplexer in reverse with 2 rigs and 1 antenna

Paul Butzi (W7PFB)
 

I am confused.

Comet list the triplexer in the photo as having at least 40db isolation between ports.  3db is a factor of two, 10db is a factor of ten, 40db is a factor of 10,000.

So I am thinking if you run 50w into the 2m port, the most that can appear at the 1.25m port or the 70cm port would be 50w/10000 = 5mw.

If I’m wrong I sure want to know, as I have three radios hooked to exactly this triplexer all routed to a Comet CX-333.  I would prefer not to blow up a radio.

Comm Academy

Rowland
 

FYI....

Greetings!

The Leadership of the Communications Academy is reaching out to all of our loyal attendees who have made the event such a success in the Pacific Northwest over the last 22+ years, to give you an update on our plans for 2021 and beyond. 

First, thank you for your support, interest, and willingness to grow with us! Without your continued attendance, financial support, and volunteer efforts the event programs we have offered would not have been possible.

As you know, however, we had to cancel the 2020 in-person event. The Communications Academy leadership has used the challenges of 2020 to review how we can best preserve the direction and focus of our event while restricted by the pandemic. Our first task has been to review how we can provide an outstanding online presence that will engage all of you with great content and an opportunity for all of us to connect throughout the year. 

The annual event has continued to evolve by presenting keynotes and seminar tracks that engage beginners, intermediate and advanced users in technologies, served agency support, volunteer management, self-preparedness, and how volunteer and professional communications are used, adapted and improved. All of that will be true of our 2021 virtual Comm Academy. What’s more, as an online event, we will have an unprecedented ability to connect folks from anywhere in the country—or the world!

While we’re not ready to publish the agenda of presentations yet, you can still check out the new website, and if you’re on social media, follow us on TwitterInstagram, and Facebook, and invite your followers to do the same. And while you’re looking at the site—please go ahead and pre-register! We’ll save a spot for you, and keep you informed as the event takes shape.

A name change seemed to be in order reflecting our new approach with our website. The Communications Academy will now be known as The Comm Academy. We all have called it that for years, so why not make it official?

Comm Academy 2021 is currently planned for April 10th and 11th, 2021. More details will be available after January 1st, but hold the dates!

In closing, we are excited to move forward to continue the tradition of Comm Academy. Your engagement, feedback and support are welcome as we look to 2021 and beyond.

 

Sincerely,
The Comm Academy Team

Thanks,

Rowland

Re: Mike & Key Swap Meet Cancelled

Rowland
 

Tony,

Here is what was recently sent to those that have already bought booth space.  Make your own conclusion.

"As of Tuesday Nov 10th, the Mike & Key has canceled the Swap Meet for 2021. Even with the promise of vaccines, the climbing curve of new COVID cases convinced the Fairgrounds to move our deposit to 2022. It all just moved faster than we expected. Next year, we will start again, hopefully with a better prognosis. If you preregistered for this year, it will hold for 2022.

In the mean time, what do you want us to do with your check?
I can shred it or mail it back to you. Your choice.

Best wishes for the upcoming holiday season. Hope we hear from you next Fall.

cheers
Michael Dinkelman"


Thanks,

Rowland

Perfect. Thanks for verifying that I wont blow anything up on TX 😊

 

Paul – that’s exactly what I’m trying to do – share my CX 333 antenna with my TYT 220 and my 9700.

Yep, that’ll work.  I do this (admittedly with three radios) in my shack to route signals to/from the CX-333.

Hey Snovarcians,

I have a triband antenna that I'd like to share between two radios: 1) a UHF/VHF and 2) 220Mhz.  Rather than use a switch - which would only allow me to send/receive on one rig at a time. I was wondering if I could use a triplexer to direct the 220mhz to one rig (obviously the 220) and the 2m.70cm to the other rig so I can keep both rigs listening and transmit on either one. I know this will work for receive only but will I blow up a rig when the other is transmitting or will the triplexer keep the output separated? Has anyone done htis?

Would the group be interested in a short NanoVNA demo on Thursday 6pm before the Rookie Roundtable? A couple people have requested this and, with the social distancing, it will be a while before I can bring it to an in-person event...   so let's Zoom it! 

Based on responses and availability of others we'll make a decision in the next 48 hours but I'm ready to do it if you'll join. Let us know! 

I'll be focusing on using the NanoVNA as an SWR tester for antennas. The topics will include:
· Hardware overview
o Example hardware / where to get
· Set to show SWR (easy)
o Trace
o SWR
o Scale (.25 a line)
o Stimulus
· Calibrate
· Save Calibration
· Recall Calibration
· Sweep 2m and 70cm
· Zoom to 70cm
· Show two different antenna tunes
· Sweep HF ant
· Identify where HF ant is “tuned”

This web site      Link:   HAMQSL.COM      has all kinds of information and explanations for propagation.  It is the website where the icon on the top right of the main page of the QRZ web site links to.  There is a page that explains all the parameters affecting propagation.
