In lieu of a Truly Accurate impedance bridge, this sounds like a job for the old MFJ whatever-the-number analyzer. I just finished reading a long-winded paper that asserted that metal oxide had less
Very interesting responses, thanks. DigiKey stocks some Stackpole RNC and "RNCS", which Stackpole claims are "Ideal replacement for costly Tantalum Nitride resistors" . I wasn't able to quickly find
It's not the solder itself that makes the mess. I use solder that apparently has a lot of rosin flux and it leaves a mess on the board. I know there's flux strippers available, but haven't yet tried
I second the Novus suggestion. I use it on my acrylic/plexi windscreens and face shields all the time. If you have scratches that you can feel with your fingernail, start with all visible scratches a
The "25% rule" has worked in the past. Some comments, tho: . It would be interesting to know what the community thinks is a good set of operating conditions for an AL-80A on AM. Considering the AL-80
Assuming the item is otherwise clean: One relatively low-risk method is to line a glass dish with aluminum foil, then soak the item in a heated (boiling or close) preparation of 1/4 cup ordinary baki
Then that begs the question - Marketing claims aside, what would be an appropriate max output power to run with a SB1000/AL80 ? It's a timely question for me, at least. I have a nice SB1000 that's be
I was thinking 100 watts carrier/400 watts PEP AM, actually. That would allow me to use the Flex 5000A at roughly the same output level as my old Johnson Viking Valiant. I'm not a "10 minute club" me
Heh... Well, I was considering operation at 100 watts carrier, 400 watts modulated. I doubt my tubes, PS and other tender components would tolerate 1500 watts carrier and 6KW PEP long enough for the
From my Henry 3KA manual: "The 3KA is a 3000 watt PEP input (2000 watt nominal output) linear amplifier ..." On the other hand - I wouldn't think a direct comparison to a SB-220 (even with a Dahl tra
Not to start any trouble here, but what about the newer software-compensated meters/directional couplers sold in the ham market? A quote from a well-known model's marketing material: "Power accuracy
My 3KA runs around 4050V unkeyed @ 247VAC line voltage. (line voltage is high and stiff here) And it does have the choke as well. I could look up the bleeder resistors if anyone is interested in the
Here's a question from another angle: Say I use two 8877's instead of one (with proper cooling and whatever else is required) and run 1500W PEP output SSB, would the two tube version run more hours t
And I'd like to hear more about expectations of what a single GS-35B will do under in-spec operating conditions. Bill's numbers are in-spec at the edge of the published limits. My question has to do
Thanks to those that replied with the "Prometheus". Whatever the reason, it hadn't grabbed my attention until now. I'll do a little investigation, but at first glance I didn't see any review referenc
Apologies for hijacking the thread, but speaking of the Alpha 77 bias, is there a preferred method for defeating the "active" part? I remember seeing somewhere that some revs had a pot for adjusting
That's about what I get from mine. Which reminds me - I haven't had power on it for a couple of years. I wonder if anything will go 'bang' when I turn it on... 73, Jim, N7CXI ________________________
Assuming one doesn't insist on using the Millen connectors, what's a good alternative? Someone mentioned RG-214 a few pages back but having been there, done that and arced most of the common connecto
Good point. Since we're on the topic, I've seen references to Fair-Rite #31 toriod cores in various places, but haven't been able to find any in their catalog. Do they actually exist in the wild? Bea
Aha! I hadn't thought to check the "cable core" dimensions for one that looks like a toroid. That was the missing piece. They don't specifically have toroids in #31, but they have cable cores with th
