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. Greg KO6TH Erik - W6EMR via groups.io wrote:

Jetstream JTB3 dual-band base station antenna FREE FREE FREE
Jim - N6MED
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! -- Jim

Just a few photos.
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.

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. Phil KM6NFS

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: Joe K6SAT, call for WSER volunteers: https://www.youtube.com/watch?v=vX5DivLDTwQ Orion AI6US, on Winter Field Day: https://www.youtube.com/watch?v=H9WqNOeknOE Clyde AB4CC, on the W6EK Repeater System https://www.youtube.com/watch?v=HEnFpcgl1SU Enjoy!

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. -- KK6VHH - Joshua piratesinteepees.org youtube.com/piratesinteepees

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! 73, KM6YKX, Rob (I can quit this hobby anytime I want ;o)

Re: Nashville bombing spotlights vulnerable voice, data networks
Jef - N5JEF
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. - Jef N5JEF

Re: Nashville bombing spotlights vulnerable voice, data networks
Aaron K6ABJ
Thank you all for the great information on and suggestions for an Near Vertical Incident Skywave (NVIS) net! I had fun learning about NVIS, and was pleased to know my present OCF antenna although compromised for DX due to low height above ground is perfect for NVIS. I want to especially thank Jim N6MED for bringing this topic to my attention, Greg KO6TH for the link to Jim's video, and to Jim N6MED for his NVIS presentation. I will definitely be having fun on the airwaves with this information! Aaron, K6ABJ On Mon, Jan 4, 2021, at 2:59 PM, Jim - N6MED wrote:
