  1. Hi Bob. Welcome to one of the hardest simple problems to fix! The dimmer is picking up the signal, period. Some will tell you it's because the dimmer is actually a PWM and that you're changing the duty cycle of the AC waveform. Others will tell you that the dimmer is simply acting as an antenna. Regardless, the problem is fixing the flicker and that's difficult to do. Many have tried toroids near the dimmer but that means, if it's a wall dimmer, digging into the wall! Not ideal, right? If the dimmers are external, then you might have a chance with, as you suggest, some good ferrites. Another solution is to use a smart bulb with dimmers built in. They are usually immune but I don't know how many bulbs we're talking about. If you're dealing with 25 bulbs, that's going to cost you; if it's three bulbs in the living room it's a worthwhile option. Quick questions: Problem on all HF bands? Same (or similar) flicker frequency on all bands? To fully debug, and to confirm or rebuke my assertive "it's the dimmer" statement, do you have any tungsten filament bulbs lying around (obviously with the same size socket). Try those just to put your mind to rest that it is indeed the dimmer. Add anything else you may not have thought of. Jim
  2. Hey Bob, that's fantastic! I agree, FD is a great time to meet or regroup with fellow operators. Ours was nice too!! Which club were you with?
  3. Two questions for you. How will the time affect the log? Also, how was the dog 😉 Let you work?
  4. Welcome Michelle, glad to have you on-board!
  5. Ouch. I can't imagine working a key without that firmness or springiness. What I don't understand, is how the key comes back to center rest...
  6. I’m sure it’s no consolation, but I was fortunate enough to connect with several VE3s this weekend. I actually almost got a VE8, but ultimately I couldn’t pull him in. Hopefully you can participate next year!
  7. @KB3VBL, welcome aboard!!
  8. Had a good time? Bands were good? How was the food? The weather? Everyone went home safe and without too many cuts and bruises? As important, lots of QSOs? I'll start by saying that ours was very good. All went well. I think everyone had a great time, the weather I must say was awesome for us; it was a little less hot than we feared and the rain came, literally, ten minutes before we had finished tearing down, so just in time to cool us off. All were safe, except for one tiny nose cut on, of all people, our safety officer (oops). And yes, as visible in the photo, we concluded the day with our traditional ice cream outing. How about you?

    The ARRL Sections of Virginia and Maryland DC, and Ham Community, are pleased to invite you to our First Annual Amateur Radio Cross-Potomac Summer BBQ. This is our chance to mingle with fellow amateur radio operators, both from clubs right next door and from the other side of the Potomac. This is not an operating event or a hamfest, it’s what it says, a good old BBQ, with some music, a couple of fun ice-breaker games, the usual tasty BBQ nourishment, very few and very short speeches, maybe some QSL card swaps, and that’s it. And it’s in the fresh air, so no major worries about covid, though we do encourage those that are at risk to observe recommended precautions. Name tags and club swag encouraged! LOCATION: Seneca Creek State Park, 11950 Clopper Road, Gaithersburg, MD 20878 SUBLOCATION: Nuthatch Pavilion DATE: Sunday 21 August 2022 (rain or shine, but remember, the pavilion is covered!) TIME: From Noon to 1700L FEE: We ask $20 per person to cover all fees, food, refreshments, etc. – Children under 18: FREE. Note that admission to the Park is payable at the gate – let's support our State parks! MD resident: $3, Out-of-state: $5; Veterans: free. We are limited to 200 people so book as soon as possible. You cannot pay at the location - tickets must be pre-purchased online. If you can't attend, we're not complicated... a full refund will be issued as long as you cancel up to the night before 1159L. FUN ACTIVITIES: THE HAM HISTORY CHALLENGE: Let’s see how well we all know our amazing journey? Can you identify a KWM-1 by just looking at one of its knobs? Do you know when Field Day was first held? Do you know who sent a signal between two kites in Virginia in the 1800s? THE TABLE KNOCK CW CONTEST: It’s one thing to read a beautifully clean signal sent from that superb bug or paddle key, it’s another to read a table knock. Let’s have some fun ‘knocking out’ some Morse. POTA: More info to come, but we are in a park, after all. ORGANIZING COMMITTEE: You are being jointly invited by ARRL VA | ARRL MDC | HAM COMMUNITY Jack Smith KE4LWT - ARRL VA Section Manager Marty Pittinger KB3MXM - ARRL MDC Section Manager MDC Mike Aimone WA8AHZ - ARRL VA Section ACC Chris Van Winkle AB3AWG - ARRL MDC Section ACC Jim Alyanak K3MRI - Ham Community Jonathan Vomacka W2JVO - Ham Community Ilhan & Maria Alyanak - Ham Community DRIVING DIRECTIONS: From Washington, D.C, Virginia and points south: Take I-270 north towards Frederick, Maryland.

    FD RAR 2022

    HC’s K3MRI spent Field Day 2022 with the now 51-year together team from RAR - Randallstown Amateur Radio club. The weather was perfect, including that nice rain shower that literally hit us ten minutes before we completed the tear down.

  17. For years I’ve tried to define Field Day, not in an absolute, definitive or comprehensive way but rather, in a personal one. What does it mean to me? I have narrowed it down to two key added values, again, for me. First of all it is the camaraderie. I spend Field Day in a group setting. I do not operate alone. Secondly, more than the ‘contest’ aspect, even though it is technically not considered one, I find that Field Day is an exercise in ‘aggregation.’ Individuals, with different radios, different feedlines, antennas and power supplies, show up on the Friday or Saturday and are expected to magically make it all work together. Except for the most avid contesting clubs, there is little to no real preparation. Sure, so and so will bring the CW station, and so and so will bring the SSB station, but is there really any real pre-matching? Not really, and yet, it works. I’m sitting here at this year’s Field Day, with a group that has been together for 51 years, and yet, it’s as disparate as I describe above. Multiples of each needed item show up, and maybe because they’ve done it for years, everything somehow connects and they get on the air. If you think about it, this aggregation characteristic provides a foundation for many aspects of amateur radio. Of course, emergency responses are made possible by this quasi-instantaneous aggregation. So too do the more mundane public service interventions. Every year I participate in the Marine Corps Marathon. Over the past few years I’ve been attached to Net Control. Here again, ‘stuff’ shows up, and like magic, we have a net control station able to transmit to and coordinate with over one hundred portable and mobile operators. That’s it for now, I guess I should get ready for my own Field Day. And yes, I better remember what I ‘brought’ so that I take home what’s mine and not what’s everyone else’s.
  18. What an absolutely fascinating and informative interview. Enjoyed every minute. Did I miss in what year this was filmed?
