Re: New base antenna install + old antenna & mount #antennas

Erik - W6EMR
 

The mag mount antenna ( 36" tall) is what I have been using for the last year or so. SWR was 1.3 across the whole band, no adjustments made.
The gain was rated at 3.0 dBd, but with 75' of lmr 400, I was probably at unity gain.
The new one is rated at 5.2 dBd and is over 7 ft. Tall.
Roof is 27' above grade.

Hi Erik,

That whip antenna (lower left)...  Interesting mount!

But the antenna's base (the black part) looks like something that's intended to mount on a car roof or such, i.e. a ground plane.  If so, the bracket probably isn't enough, and you might need something by way of counterpose wires or elements to make it resonate / radiate properly.

Old magmount antenna is Cushcraft cs-270m (no longer manufactured).
New antenna is Hustler CG-144 with MKR-2 radial kit.
Initially, swr was over 2 to 1.  I Had to remove 2-1/4" from lower section to get a 1.2 swr.
Half-wave loop on the bottom for 2 meter SSB work.
Jetstream JTB3 dual-band base station antenna FREE FREE FREE

Have taken my JTB3 out of service. Still works jus' fine. VSWR remains <2.0.
There's only one catch: I'm offering this antenna for the paltry sum of $0.00 to a new Tech-licensed member of our club. For anyone else, there will be a surcharge ;-)
The "buyer" will need to pick it up at my domicile in Citrus Heights or at a meet spot somewhere in my locale.

Just want to pay forward for all others more seasoned hams have done for me in the past.

Contact me at my email address above or at 530-401-4838.

As to everyone that reads this: be safe and be well!

DIY Antenna Tuner Video

Phil - KM6NFS
 

I came across this article about videos by ZL2CTM showing how he designed and built a simple antenna tuner.

https://hackaday.com/2021/01/15/manual-antenna-tuner-shows-how-homebrewing-is-done/
I like the build and I like how he went through the design steps and followed up with a demo using the NanoVNA.

January presentation videos up on YouTube (and a request!)

Greg D
 

Hi folks,

The presentation videos from this month's SFARC General Meeting are up on our YouTube channel.  There are three this month, with Orion's Tech-10 talk about Winter Field Day (coming in 2 weeks!), Clyde's inside-view of the new W6EK repeater system, and adding Joe's request for volunteers for the Western States Endurance Run.

A request:  For next month (February 2021), the plan is to have Clyde follow up with a bit more information, particularly on the 2 Meter repeater which is still undergoing some change.  If you have any questions about the system, please let me know and we'll try to have it addressed.

Links are as follows:

W6EK 2m AllStarLink, Echolink and Broadcastify will be down for a few days.

Joshua - KK6VHH
 

The upgrade to new Internet service in the vault has caused some connectivity issues (firewall needs to be tinkered on).
Our Clan of Ninjas are working on it and it should be back online in a few days. 

Until things are fixed, the following services will be unavailable:

W6EK 2m AllStarLink, Echolink and Broadcastify

Repeater is working for all other services. Thanks for your patience.

2021 Dayton Hamvention CANCELLED

So goes 2021

Begin forwarded message:



2021 Dayton Hamvention Cancelled


Citing "several setbacks in the recovery from the COVID-19 pandemic," the Dayton Hamvention Executive Committee has announced the cancellation of the 2021 event, scheduled for mid-May. The announcement cited the slower-than-expected rollout of the COVID vaccine as well as the even-more contagious variant that has emerged in recent weeks.

This is the second consecutive year in which the pandemic has forced cancellation of the world's largest hamfest. The committee says tickets that were deferred from last year will be deferred again, and that plans are in the works for another on-air Hamvention QSO Party on what would have been the Hamvention weekend.

     I know we are all in shock as to the news of losing A great man and friend Dave K6VHP this past week. Today I spoke with Renay Dave’s Wife and she ask me to share with you all what happened.  Dave had been doing well thanking of returning to work soon, that morning he went to have tires put there car and had returned home and was found by Renay Unresponsive at around 1 pm and had suffered a heart attack and EMS was unable to Resuscitate him. Renay is doing ok and has no needs at this time she is in close contact with Dave’s family and will reach out through me or his face book page and let us know when there may be a Memorial Service. She is monitoring his face book page and posting information there as well. 
 
 God Bless you All!!!!

Re: Nashville bombing spotlights vulnerable voice, data networks

KM6YKX - Rob Newburn
 

I like the net idea too.

I've also had success with getting on the W6EK repeater (or other repeaters) and seeing if anyone wanted to try say 80 meters in the middle of the day (or 6, 10, 17, whatever). I was very surprised to see that it often works very well, even when the fish finder looks kind of dead. Same with trying 2M FM simplex...it's good to know who can reach who with no infrastructure in case the need arises for a relay net. For a short time, some of us in the 2MC were "band hopping" in the evenings just for fun and experiment...starting on a repeater, going to 2M simplex, then 2M sideband, then HF...others tried to follow if they could or they might listen on Websdr.com. Always had the repeater to fall back on for spotting.

Anyway, good thing to practice, experiment, have some go to frequencies, get to know your equipment (manual tuner settings list for various freq., etc.) and get to know some other hams out there.

So shout out on the repeater if you want to try/experiment/make antenna changes/try different antennas to see what happens!

Thanks for keeping me up late last night!

I strongly support the idea of a regular NVIS net.  Maybe immediately after the club net each Thursday night on 75 meters.  I would be happy to help with suggestions for antennas to meet various member's real estate.

Indeed why we have radios and the vulnerability of our public telecom network.

So far as Winlink support of disaster communications (Winlink moved to AWS from its own servers a few years ago), the outage did not affect Winlink. However, that outage gave me pause to think about our own communications plans in the event of a disaster. Certainly Winlink for digital and the various digital phone circuits, good for long haul so long as the Internet is up, are particularly vulnerable. What plans have we, those who support NGOs and those gov't agencies open to using the amateur radio services, for working through telecom service degradation?

For example, late last June a wild land fire in the Susanville area took out ALL of the public telecom infrastructure serving Susanville. The local ham club had three repeaters, all digital. During blue skies they had world-wide comms. During the fire all they had was local comms between the three machines. The only way to get traffic in and out was, literally, Chevy Net. They had made no provision or connecting with any agency (e.g., ARES or CalOES CRU) for such an event.

IMHO, we would do well to develop both hardened repeater systems (or ensure existing ones are hardened) and an HF NVIS net, all in the event of. Winlink has the provision for P2P connections. We at the Red Cross CA Gold Country Region are working toward P2P NVIS for the purpose.

Just some thoughts from N6MED
