Hello,

The next Club community volunteer event is less than two months away - MS Walk in Folsom - April 26!

This event lasts less than three hours. Net Control is at historic downtown Folsom, with three radio stations at rest stops on the route. An HT with a good antenna is sufficient to communicate with Net Control. This is a great opportunity for new hams to test their radio skills with their HTs.

Our job will be to relay communications between event control and the field stations, as well as any incidents from the field to event control.

Please let me know if you are interested in joining us for the event. I will provide instructions on signing up.

Re: Coronavirus info

Statistically, this means:

Flu mortality rate went from .01 to .02% death rate and Conavirus mortality is 2.3%.

From what I have been reading, the risk of exposure to the conavirus is greatly increased due to the excessively long time that a carrier can expose others prior to exibiting symtoms.

I like my chances of living after catching the flu much better! 🤪

Glad i moved my investments out of the market last Friday! This is getting ugly!

Before you go getting all paranoid on this information, consider that according to the CDC: Flu deaths up in the new year: CDC Flu deaths are up more than 65% so far in 2020, with the Centers for Disease Control and Prevention reporting that 4,800 people had died and 87,000 people had been hospitalized.

Edited

The Perserverance DX Group is operating from South Orkney Islands until March 6th. Lot's of people calling them right now as they are number 15 on the list of most wanted DX. The attached propagation wheel shows the best times (outside circle in UTC) and bands (vertical pie slice in the middle of the circle). You can see by this that your best chance from our QTH in Auburn starts about 2300 UTC (20m) and goes to 0200 UTC.

Although, 15m looks good from 1600 UTC until 0100 UTC. So, you might want to try that band as well.

The DXpedition website link follows:
https://sorkney.com/

You can plot your own propagation wheels at: https://www.voacap.com/hf/

Note: I've found that looking up your (and the DX station's) grid square using QRZ "details" tab, and placing this info in the appropriate boxes, gives the most accurate response from the application.

Cal OES News [2020-02-27] Grass Roots Radio Solves Rural NorCal Community’s Disaster Communication Quandary

Cal OES this morning published a brief article and link to a 3-minute YouTue video on the value of GMRS radio for emergency communications and awareness.

Grass Roots Radio Solves Rural NorCal Community’s Disaster Communication Quandary

Residents living in one rural Northern California community were tired of feeling helpless during recent wildfires and public safety power shutoffs. They didn’t have the ability to communicate with friends or loved ones because cell service, land lines and interest were all down. So, they took it upon themselves to solve the problem, at least for their own community. They gathered their neighbors, communications experts and first responders and came up with a plan. Their solution was GMRS: General Mobile Radio Service.

Thank you to the Grey Fox in Oroville for allowing us to use your facility for the interviews with Lois and Marisa.

As it has started around here, read this and make your plans:

The Centers for Disease Control and Prevention always recommends everyone should always take simple daily precautions to help prevent the spread of respiratory illnesses. - Avoid close contact with people who are sick. - Avoid touching your eyes, nose and mouth. - Wash hands often with soap and water for at least 20 seconds.

February Presentations up on YouTube

Hi folks,

Just a quick note to let you know that the presentation videos from our
February general meeting are up on the club's YouTube channel.

As a reminder, Orion AI6JB gave us a review of the club's Winter Field
Day event.
https://www.youtube.com/watch?v=7fPZWUZuLbs

Also, Bob K6UDA gave us a peek at the Yaesu Fusion Digital Voice test
that we are running on the club's 70cm repeater.

This was a fun, casual contest for me!! ... Everyone on the band was looking for a US station. I worked Search & Pounce for most of the 5 hours I was on, then called CQ the last 2 hours, after I had pretty much worked everyone calling CQ and picked up a bunch more. Lots of interesting contacts this year, and one "all time new one" for me, Guernsey, and island in the English Channel, between England and France. Lots of big DX stations with BIG antenna farms too. So, you don't have to have a big station for this contest, just good ears to sort out the pileups.

Some notable contacts you don't typically hear unless there is a contest were: Croatia, Madeira Island, Cayman Island, Curacao, Ireland, Netherlands, Portugal, Bosnia, Bulgaria, French Guiana, Guam, Latvia, Lithuania, Martinique, Montserrat, Poland, Scotland, St. Kitts & Nevis, and many, many more EU.

I ran 200w to an end-fed long wire from a remote in Richmond, VA to rack up:

183 Contacts
53 Countries on 6 continents
40,404 points (but whose counting?)

So, you can join in the fun on March 6th for the SSB version and have some fun trying to understand all those interesting accents. Well, that's the beauty of CW ... no accents!

Hi folks,

Putting out a bit of an APB... A couple of years ago I was talking to
someone at our club picnic in Applegate about DMR and what magic they
could do with their DMR handheld. I forget who that was. Anybody
remember (and be willing to admit it)?

Thanks,

Re: 1:1 Choke Location on Beam Installation

Brian Gohl - AI6US
 

Thank you for your replies. Great information and references.

Wow!!! The K9YC link has an incredible trove of information. I think that I will be referencing that site often! Thanks Dennis!

Thank you Jef for the feedline length explanation. The hexbeam is 6m-20m, but in testing the 6m band, it is very inefficient and will likely not be used much. Your examples certainly confirms the concerns regarding the interactions of a radiating jumper on other frequencies. I will be using a 2 foot LMR-400 jumper to place the isolation choke weight near the bottom of the hexbeam center post, use a 3 foot LMR-240 UF coax jumper for the rotor loop then a barrel to transition to the LMR400 run to the shack.

Thanks again!

Re: 1:1 Choke Location on Beam Installation

Jef - N5JEF
 

Brian -

The choke really should be at the antenna feed point. It is intended to present a relatively high impedance at that point, and minimize common mode radiation from the feedline. 

What's your highest band on that beam?

As you know, a quarter wave transmission line transforms an open circuit to a short, and vice versa. 

So, at 10 meters your 6 feet of coax (remember also consider the velocity factor) will be roughly a quarter wave and your choke will have roughly the opposite of its intended effect. At 20 meters, roughly 1/8 wave, so the transformation, as seen at the feed point, will be somewhere in between, and certainly not the high impedance as designed. 

That said, ham radio xperience tells us that antenna theory is all magic anyway, and you'll still make contacts proving it works great. 

So FWIW, have fun.

Subject: [from W6EK Groups.io] 1:1 Choke Location on Beam Installation
 
Prepping to permanently install the hexbeam at my home QTH this weekend and researching the install location of the 1:1 line isolator choke.

I understand that it is recommended to install the choke at the antenna feedpoint, but I am looking for guidance on instead placing the choke inline at an alternative location below the flexible coax rotor loop. Are the any issues to consider if  installing the inline choke at the top of the tower then running a flexible coax approximately 6 feet up to the hexbeam feedpoint? Working 6m - 20m bands on the hexbeam, would the jumper length between the choke and hexbeam feedpoint have any influence? Would a 6' vs a 6" jumper have any effect on interaction (common mode???) if a VHF/UHF antenna were to be co-located on the tower?

Mounting the hexbeam's 1:1 balun choke in this location will reduce the number of connectors on the tower to transition from the flexible rotor loop coax to the stiffer LMR400. The choke would be able to dual purpose as the coax transition barrel.

Thanks for any advice!
