Clint Bradford, K6LCS, will be presenting his 84th “How to Work the FM Amateur Satellites With Your HT” session at the Downey (CA) Amateur Radio Club on Thursday, September 1, 2016 at 7:30 PM. All are welcome to attend.
“DARC has been a long-time supporter of the ARRL, quite active in their region for more than 50 years, and I am honored that they are asking me to speak,” Clint writes.
Save the Date….
Come on out and join the fun on October 8th operating the Downey Amateur Radio Club’s 65th Anniversary Special event station. Hours of operation will be from 0800 to 1600 PDT. The location has not been finalized; however, it will be in Downey. More details will be published here and in the October issue of the Q5.
June 24th, 25th & 26th
Setup will begin at 1100 hours on the 24th
Tomorrow Saturday the 21 is our next scheduled Thunt. Be at the top of the Kirkorian parking structure at 9am. (corner of new and 2nd) where we will find the general direction the signal is coming from, then take off in our cars to chase down to the hidden transmitter.
All it takes is an HT and directional antenna like the measuring tape yagis we built to hunt it down.
You are welcome to come by and watch or go along with someone else if you want to see that THunting / Foxhunting is all about.
See you there.
Mobile Contesting from HF to Microwaves.
Our Club President Dave, N6TEB will be our speaker this month. Dave has spoken at several SoCal Radio clubs over the past several years on Roving in VHF contests. In his updated presentation Dave will cover the challenges of operating mobile from HF to 24 GHZ. Special emphasis will be focused on what it takes to get on the upper bands where there is no commercially available gear available.
First licensed in 1970 then relicensed in 1982 Dave holds an Extra Class Amateur Radio license and a General Radio Telephone Commercial Radio License (formally called First Class Commercial). In his early days he worked at several Los Angeles Radio Stations and Hollywood Recording studios before migrating over to the Software industry. A life member of the ARRL he has been active in mobile contesting since the mid 1990’s taking the top spot or at least showing up in the top 10 for several years. Almost all his installations featured no holes drilled in the body of the vehicle. So come on out this Thursday May 5th and see if you can get some ideas for your own mobile station.
If we build it, they will come.
Contacts of course. This month’s meeting will feature our J Antenna building project. This is the first time we have tried such an ambitious project at a club meeting so please come prepared to build a copper J pole antenna. The cost is $15 and we have had several sign ups already.
I will bring enough extra ½ cooper pipe for 3 or 4 extra antennas. You will have the option of building a dual band VHF UHF version or a mono band version. The difference being a mono band vhf or uhf will typically have a better match as the dual band will be a compromise for reasonable match across both bands.
This project will require map gas torch soldering of copper pipe, if you have never done this or just plain don’t want to play with fire one of us will help you.
The trickiest part is the feed point. We will use a hose clamp to hold the coax or connector in place as we move it up and down for the best match. Once found it is up to you if you just want to solder some coax directly to the pipe or install a coax connector. Each method has its own challenges. Soldering coax means you will need to wrap the connection points with weather proof table and installing a connector requires some way of attaching the connector flange to the pipe. We will have both short pieces of coax and SO239 (UHF) female connectors commonly referred to as a “Hillary” available for your choice.
We will be doing this project out back of the building where we meet, in the parking lot so as not to drip molten solder on the carpet.
Someone bring a fire extinguisher and a bucket of water.
Arnie Shatz, N6HC, will be our guest speaker for this month.
What is it like to plan a three week DXpedition to an uninhabited piece of real estate in the middle of the Coral Sea with no Radio Shack to bail you out if you need some coax or a barrel connector? What does it sound like at the DX end of a pile-up? Why do 12 sane men even want to take on this type of adventure?
Answers to these questions, and more, will be explained by Arnie – N6HC, who was one of the participants of the TX3X DXpedition to Chesterfield Island in October, 2015. So bring your flip-flops and sun block to the February 4th club meeting and be prepared to be entertained at the island beach party!
