I like to DX, but with my current setup, I'm somewhat limited (still at 187 in 8 year however) I probably have the most fun operating in contests, but tend to prefer the smaller ones, where I'm not t
Well, today was the day, John W2GD and Bill W2RQ, along with Pete, W2IRT came and installed my rooftop Glen Martin and 2 antennas, a C3SS to cover 10, 15 and 20 (and yes, it DOES tune 17m with a tune
...snip... ...snip... OK, so far I'm VERY VERY happy with what I've just installed, and I'm hearing things I've never heard - the question is, what's next I just installed about the largest tribander
I've bought a stack of ball bearing balls over the years, and not once did I have to spec alloy and hardness. You buy "Ball Bearing Balls". Let's face it, our rotors are not high speed, high precisio
I started an off list discussion with Peter about this. I did almost exactly what he proposed only 6-8 weeks ago, except I used a C3SS and the total stack height is lower. In my case, I looked at add

Hi Gang, Back in late May/Early June, John (w2GD) installed a nice rooftop antenna system for me (love it). Now I had done a search of the rules myself prior to having the system installed, plus talk
Hi Gang, I hope this is considered "On topic" as it's antenna system related Back in May, when I put in my new antennas, I put in an Ameritron RCS-4 antenna switch, and I still think it's the right s
Yep, probably how I would have done it too It is - I'm a professional coder, and PICS are not hard, BTDT, got the paycheck - I was thinking arduino more for "it's easy for the readers to learn to rep
OK - that's exactly what I was talking about building when I said a decoder chip - Perfect - add in my 3 (or 4) relays, and I'm done, no need for me to re-invent the wheel Thanks guys - saves me a BU
...snip... The 4th relay would NOT be switching any of the remote relays, believe it or not - it has ONE use - to light the LED on the front panel - Yes, I can use the NC side of the three in series
Like I said, that's why I was thinking using DP relays, the second pole for the LEDs - and use 4, one for each LED, and it makes the using wired or gates simple Think - "How do I explain how to do th
Exactly what I was planning, and plan doing the with the UnitedMicro board - at $18, it's hard to justify making my own - Yes, I can do it a little cheaper, but not on a PWB _________________________
Hey Gang, Reading the Nth thread on lubing thrust bearings, and just had a thought - would it be a good idea to design a thrust bearing that works based upon an 'ultra high molecularly weight filled
The reason I brought up rulon/vespel bearings is because you DON'T have to climb the tower to lube them, no zerk fittings because they don't NEED lube, and trust me, they are "real bearings" - as in
BTW - you realize that that bearing is NOT a thrust bearing, and is NOT really rated for axial loads - BEST case (using a grub screw type on an unhardend shaft), that bearing is rated for 20% of it's
A place I worked did a LOT of toroidal core winding. One of the ways of keeping the wire neat was they had a spring loaded clamp, that was lined with what was basically a rough, deep synthetic velvet
