Kevin K9NSE, Great job! A true labor of love and respect for the hobby. Your arms must still be aching after all that rock steady "Armstronging" of your phone/ camera Kevin. Hope to make OzarCon

All, I want to say I had a great time at OzarkCon!  Everyone I talked to was very friendly and interesting. I hope you all enjoyed the presentation on KiCad. There is a lot to learn and I really

Hi Bob, Antennas are the magic part of ham radio. Your 4sqrp tuner is a great one, basically designed for use with a "random length wire" antenna and a counterpoise wire. For portable use, the antenna

I've found the same thing, Curt. Using ExpressPCB to make SMT toner transfer designs, the footprints that are standard are no-doubt fine for machine assembly or paste & heat, but if you are using a

The Sparkfun libraries are a good resource for getting started. I use Eagle extensively, and generally Mouser has libraries available for most parts they stock. I usually order most of my components

Well, as it happens, just now found the SparkFun libraries https://www.sparkfun.com/EAGLE , which look promising. Not sure how missed these. I am going to wander through those parts to see what the

Bob, ESD mats are for benchtop usage. The same applies to the Craft E Mat or the Kasis S-140 previously mentioned before. Large ESD floor mats or even ESD floor paint exist, but they are mostly

Is the idea to use this on a bench as a work surface or on the floor under your feet? Bob KG5GTE > I had problems following the links. I went to Amazon and searched > for Bertech Rubber ESD and

Hi Curt, Like you, I prefer to have enough copper on the board to be able to work with it easily. For something like a DIP package, the lead spacing is 0.100" The drilled holes are about 0.040"

At age 71, decided to attempt learning how to design a PCB for fabrication by the numerous available shops. Selected Eagle, using the free version at least for starting, managed to draw a schematic

Hi there, My apologies for responding to this posting after having responded to a much later one before. I did investigate the Kaisi S-140 mat offered by Amazon. Not only it is neat, it is also

Hi all, Thanks for the replies. Frank, you mentioned a 4:1 balun. If I am connecting the 2-wire feedline directly to the tuner binding posts, how do I make / find a "bal-bal"? Or, are you

There were 12 entries this month, including several new participants, a fine showing.  Maybe everybody is still pumped up over Ozarkcon.  A big welcome to Steve (WB5CTS) and George (K3EMS). If my

I had problems following the links. I went to Amazon and searched for Bertech Rubber ESD and there you go........ all kinds of choices. Thanks Bill for that info, used these years ago but here in

Hi there, I sensed that there was a bit of confusion regarding ESD mats and I would like to clarify a few things, if I may. BTW, I work at an electronics equipment factory and I wear an ESD wrist

Sounds like a Norcal Doublet.... https://www.n5dux.com/ham/files/pdf/NorCal%20-%20Doublet%20Antenna.pdf 4S tuner is designed to work best with random wire antennas. But I'd try it anyway. -- 73 de

I guess I need to reiterate that everyone participating in the SSS should think about those with Bayou Jumpers (and other rock-bound rigs) and scan around 7122 (+/- 1 kHz or so) and other 4SQRP
