Re: Need Antenna help to prep for JOTA

David McGuire
 

Thank you Harold for the comments.  I found a couple of 9:1 baluns with one being good for QRP and other other being for 100w.  Both were sold out.  I wrote to the maker to ask if he had a timeframe for new units.

Re: Need Antenna help to prep for JOTA

A couple of thoughts.

Re R7: SARC has set up an R7 at Field Day on a mast with three ropes as guides staked out on the ground. As to whether your R7 works, an antenna analyzer or vector network analyzer could be used once you have it set up.

Re 15’ antenna. The wire part appears to be pretty standard so it will probably handle 100w. The feed cable looks light, but data exists for most cable if you look up the markings on it. The specified 9:1 Balun should have a power rating if it is commercial. If home brew, the designer should have disclosed the target power rating.

I have a buddipole. The antenna is rated by the manufacturer as 200w. I am using coax rated for over 200w. My limitation is the balun rated for 100w. I don’t have an amplifier so my buddipole variants are good to go with my 100w radios.

Best wishes.

BLUF: anyone available to teach me how to repair/build portable antenna?

I have not used my Cushcraft R7 in over 10 years.  Does it still work?  No idea.  My current apartment will not permit use of an antenna.  I'm thinking of taking my equipment to Canyon Lake for a weekend of ops. 

I found a nice YouTube video that gives a description of a QRP Field Day antenna, but want to know if this design can be modified for 100w use.  If this design (see attachment) can be modified for 100w use it would be much easier to use for portable ops.

The YouTube video is https://www.youtube.com/watch?v=yH0zKNNGa0s.  Thanks to Kevin KB9RLW!

HAM EXPO 2021

Bill Craft
 

 
Let 90+ Experts Help You Reinvigorate Your Hamshack!

Dear Bill

​The next QSO Today Virtual Ham Expo is scheduled Live from August 14-15, 2021 and then on-demand for 30 days.  With over 90 speakers, networking, and exhibitors, you’ll have a great learning experience and get deep exposure to new ideas, equipment, and practical techniques.   No need to travel - participate from your home or office!  Get info and your ticket at https://www.qsotodayhamexpo.com.  Here’s why you must attend:

So, so many different topics - everybody will find something of high value.  There’s content for everyone whether you’re a newly licensed ham looking for next steps to using that license or a 30+ year experienced ham looking for new projects.  Topics include (sample list):  Emergency Services; Antennas; HF Operation; Contesting; DXpeditions; Ham Radio on a Budget; Satellite Communication; VHF and Above; Digital Modes; QRP; Homebrewing; Field, Mobile; Software Defined Radio; Test Equipment and Repair; and more! See a complete speaker list at https://www.qsotodayhamexpo.com/spkrlist.html.

Watch as many presentations as you want!  A big limitation of in-person events is that you can’t watch many of the presentations (you can only be in one room at a time).  At the Expo, return anytime within 30 days to listen to any Live speakers you missed as well as explore exhibitor offerings.  At our last Expo, our 7,500 attendees downloaded 100,000 presentations.

Take advantage of our calendar technology to efficiently organize your time.  You’ll be able to download speaker times in your local time zone directly to your Google or Outlook calendar.  You’ll then have a complete schedule of sessions to join to maximize your time during the Live period with speakers that are the most important.

Check out our live round table video for attendees to interact with each other and exhibitors.  Already integrated into the Expo platform is proven technology for you to participate in live video lounges to interact with exhibitors and fellow operators.  You’ll find this is a great way to meet up with friends, talk to vendors, and network on specific subject areas.

 

ARRL, the national association for Amateur Radio®, is a QSO Today Virtual Ham Expo Partner.  FlexRadio is the Expo’s Platinum Sponsor.  Gold sponsors are Elecraft and RFinder.

National Weather Service Hurricane Training Online UPDATE

John Ralston K0RVB
 

Good morning everyone. 

We have a confirmed date and time of August 10 at 7Pm WITH the link for this training:

https://attendee.gotowebinar.com/register/4484585089295180813

ONLY go to this link on August 10, 7pm.

What better training than hurricane training from our own NWS forecast office, specifically tailored for Bexar County and South Texas.

JC is in the loop and might also be forwarding info to the club. If you have any questions, please feel free to email me at k0rvb@...


Re: Hurricane Training - FREE

John Ralston K0RVB
 

Bill... It's giving training on how to prepare for hurricane conditions, what to do if we're affected by the hurricane conditions, what are the serious aspects of hurricanes, why this year our hurricane forecast is higher than years before, basically all things dealing with hurricanes and how we can be ready for them if they come to our Texas coast like Harvey did.

Does that answer your question?
Thanks Bill.

Good morning everyone.
I'm still in the process of working with our NWS forecast office to put together a hurricane training session as they did for us a couple years ago. This would be online of course and cover a multitude of subjects dealing with hurricanes especially in light of the National Hurricane Center's forecast for above average named storms and hurricanes this year and since we've had an earlier than average start to the season, not only in the Atlantic but the Pacific, Gulf of Mexico and disturbances coming of the coast of Africa.
 
Our NWS office can only put together this FREE presentation if we have enough participants to make it worth their while.
 
I have a list of you who have responded to the earlier email I sent out and thank you very much. However, if we don't get more participation, we can't expect our NWS forecast office, to take out all the time needed to make a special training session for only 12 people.
If you would be interested, please send me a personal email, to k0rvb@...
If you have already sent me an earlier email, it's not necessary to send again or reply to this one also.
 
Our NWS office needs a head count of possible attendees. There is no date set yet, as we are trying to get an idea of how many people will attend.
Thank you in advance.

Re: Hurricane Training - FREE

J C Smith
 

My understanding is the class will be an overview produced by the NWS Hurricane center in Miami, FL.  I'm guessing it will be general information and how radio operators can assist them.  They have several active hams on their staff.  I haven't met or had the chance to hear the current Director speak but when Bill Reed was director he was a supporter of ham radio involvement.

The San Antonio/Austin NWS office has quarterly webinars with information on local weather and the 3 month outlook.  Always very informative.
