VP Says – December 2025

Comments Off on VP Says – December 2025

Hello Ventura County Hams, I can’t believe it’s December and another year of fun radio activities is coming to an end. “Where did the time go?” I say to myself every year at this time. The club had a great 2025: lots of fantastic weekends at our portable operation sessions, entertaining speakers at our monthly meetings, Field Day was a blast as always, and we welcomed many new hams to our ranks through our VE testing sessions. From my perspective, this has been an incredibly fruitful year for our club! As Dave AI6VX mentioned in his Pres Says message, the club needs members to step up and help out next year. We are still looking for a club President, Vice President, and Secretary. I wish I could commit to a full year of service to the club in one of these positions, but I will continue to help out when… Continue reading →

Welcome to December! Today is December 5th.  Thanksgiving was just last week, and next week Friday December 12th is our Club’s Decemberfest celebration.  The weekend after that is the last weekend before Christmas, and 1 week later is Jan 1st, 2026 !  Crazy how time flies, but this is how it goes for me every year.  Does time go too fast for you too?  I’ve read that our brains mark the passage of time based on new things we do or encounter.  Change nothing and do the same thing over and over again, and time will whiz on by.  Change things up, do new stuff, experience new things – when you look back, it will feel like time didn’t go by so fast.  Based on my current perception of time, I need to change things up. Something new I am building is the same portable vertical antenna that Ben K6QV… Continue reading →

The HP 6209B Power Supply

Comments Off on The HP 6209B Power Supply

By Clement Alberts KM6OKZ I recently wrote a little article about my adventures with the Tek 577 curve tracer that Robert Shank KM6RSS was kind enough to sell me.  Recall for a moment that the 577 was designed to be used with semiconductor devices.  In my case, I wanted to look at the four 7838 pentode power output tubes on the Fisher 400 stereo amplifier my father gave me back in 1968 (that being an entire project in itself).  The 577 is capable of supplying control sufficient grid and plate voltages to power the 7868-vacuum tube.   It cannot however supply a separate voltage to power either the screen grid or the filaments.  The filaments were simply powered by DC supply.  The screen grid required my obtaining a HP 6515A power supply. This adjustable little joker can output almost 2KV.   The screen grid only required 350V.  The only thing I didn’t… Continue reading →

Pres Says – November 2025

Comments Off on Pres Says – November 2025

Welcome to November! Hopefully by now everyone has changed their clocks back 1 hour.  I sure enjoyed the extra hour of sleep Sunday.  Weather is trending cooler, thankfully.  The heat wave we had last week was amazing.  It was 80 degrees outside at my house at 11pm!  Ham radio wise, we had a few contests last month – CA QSO Party early in October and CQ World Wide SSB late in the month.  I hope everyone got a chance to participate in at least one of them, if not both.  You’ve heard me say it before, it’s a great way for folks with ‘mic fright’ to make contact with folks without needing to think of what to say.  The exchange is short, formal, and you don’t even need to worry about uploading your logs if you don’t want to.  You also don’t need to call out CQ – just cruise… Continue reading →

Pres Says Oct 2025

Comments Off on Pres Says Oct 2025

Making Things Last We bought our refrigerator around 28 years ago, a no frills, top freezer, mechanical thermostat Admiral.  A simple fridge, with no ice maker or water dispenser, it did its job well, day after day without complaint.  Spacious inside, no matter how much we stuffed it, it was rare that the door wouldn’t close. We liked our fridge.  But in the past few years some issues were showing up – it seemed to run a lot, ice would build up on the ceiling in the fridge and then melt and drip on items, and the freezer temperature control was stuck.  Fixing it would require accessing the evaporator section, and that was a big job.  Was it time to replace it?  Thanks to the internet, I’ve known for many years that modern/new refrigerators do not last very long.  5-10 years is about all they’re good for if you’re lucky. … Continue reading →

Comments Off on VP Says – Sept 2025

Hello Ventura County Hams, I really don’t want to risk angering the propagation gods, but… are HF conditions starting toslowly get better? This weekend the MUF over North America was above 30 MHz for asubstantial amount of time, and I actually made a handful of CW contacts on 10m! It really feltlike foreign territory after so many months of not venturing up that high. My signal was gettinginto Europe on 20m multiple times during the day and night, and 15m seemed strong too. I’mkeeping my fingers and toes crossed that this is a sustained trend and not a one-off. This month’s club presentation is by Cory Gibson, W3JL, on near vertical incidence skywave(NVIS) propagation. NVIS is important for short-distance HF communications, which is vital forARES/ACS operations during potential emergencies. Which reminds me: there is a new SantaBarbara Section net on 80m every Tuesday night at 20:00 local time (3.987 MHz… Continue reading →

Is it hot enough for you?  I’m ready for cooler temps, but based on the forecast, the first week of September is going to be warm. The current weather at my QTH can always be found here:  http://www.wunderground.com/personal-weather-station/dashboard?ID=KCAVENTU59 Situated in E. Ventura, my weather is more like Camarillo vs the coast of Ventura. My weather station has been pushing data to Weather Underground for many years now.  For as mild as our weather is, it still does surprising things now and again.  Check out this temperature plot from last week.  Temps peaked at 97 degrees, then the winds picked up and temps fell 20 degrees in 1 hour!  Crazy! Last week I took a trip with Margaret up to Seattle to visit family.  We spent a week there, staying in a nice hotel downtown that was within walking distance to many sights.  “Dave, did you bring a radio?”  Glad you… Continue reading →

Scientific American reports that radio will soon be used to transmit music to the home

Comments Off on Scientific American reports that radio will soon be used to transmit music to the home

On October 1, 1920, Scientific American magazine reports that the rapidly developing medium of radio would soon be used to broadcast music. A revolution in the role of music in everyday life was about to be born. “It has been well known for some years that by placing a form of telephone transmitter in a concert hall or at any point where music is being played the sound may be carried over telephone wires to an ordinary telephone receiver at a distant point,” began the bulletin in the October 1, 1920 issue of the popular science monthly, “but it is only recently that a method of transmitting music by radio has been found possible.” In an 1888 novel called Looking Backward: 2000-1887, author Edward Bellamy imagined a scene in which a time-traveler from 1887 reacts to a technological advance from the early 21st century that he describes as “an arrangement… Continue reading →

Comments Off on VP Says – August 2025

Hello Ventura County Hams, I was not expecting to be writing another Vice President’s message, but here I am back again!First, I want to thank Robert KM6RSS for doing an amazing job as VP this year. I can’t think ofanother member with as much passion for, and dedication to, the club as Robert. He hasgraciously volunteered to take over the immensely important job of Secretary, a responsibilityhe is eminently qualified for. Thanks Robert! So far, this summer has been a little bit of a bust on HF. Increased solar radiation causes the F2Layer to expand upward and become less dense, making it less effective at reflecting oursignals. Adding to that, more D Layer absorption during the day attenuates signals, making thesummer feel like a real bummer. However, we are still near the peak of the solar cycle, so let’sall hope for a resurgence in our DX as we move towards… Continue reading →
